Abstract

<P>PROBLEM TO BE SOLVED: To enable a player to intervene in which one of several kinds of specified game states control is to be executed to by selecting a display result to be derived at a variable display device by his/her own operation. <P>SOLUTION: In a normal game state or RT1, control is executed to RT2 to be continued over 100 games with the extremely high winning probability of replay A when replay B is won by the display result of the variable display device, and the control is executed to RT3 to be continued over 150 games though the replay winning probability is not as high as that in the RT2 when replay C is won. In the RT1 controlled only in 15 games after the end of a big bonus, the replay B + the replay C are won by the relative high probability of 1/8. While the replay B + the replay C are won, the replay B is won when a player operates stop buttons in a prescribed operation procedure, and the replay C is won when the player operates the stop buttons in an operation procedure other than the prescribed operation procedure. <P>COPYRIGHT: (C)2009,JPO&amp;INPIT

Description

  The present invention relates to a slot machine, and more particularly to a slot machine that controls a gaming state to a specific gaming state different from a normal gaming state based on derivation of a specific display result to a variable display device.

  A slot machine generally includes a variable display device having a plurality of (usually three) reels having a plurality of types of symbols as identification information drawn on the outer periphery, and each reel has a start lever by a player. Rotation is started by operating, and when the player operates a stop button provided corresponding to each reel, the rotation is stopped within a range of a predetermined maximum delay time from the operation timing. . Then, a prize is generated according to the display mode derived when the rotation of all the reels is stopped.

  The types of winning combinations include small roles, bonuses, and replays. Here, in the winning of a small role, the player can obtain a profit that a predetermined number of medals (or game balls) are paid out for each type of small role. In the bonus winning, the player can obtain a profit that the next game is shifted to a gaming state advantageous to the player, such as a regular bonus or a big bonus. In the replay winning, it is possible to obtain a profit that the next game can be performed without consuming a new medal (or game ball) for setting the bet number.

  In order for a winning combination including a bonus combination to occur, generally, a winning flag must be set by winning an internal lottery performed in advance (usually when a start lever is operated). Here, using the fact that a player can obtain the benefit of not having to spend medals (or game balls) for setting the number of bets by winning a replay, the normal game state is determined by a predetermined number of games. There was a slot machine that controls the gaming state in RT (Replay Time) which increases the winning probability of replay without changing the winning probability of a role other than replay. Here, as an opportunity to shift to RT, there is one in which a predetermined display result is derived to the variable display device as in the trigger to shift to bonus (for example, see Patent Documents 1 and 2).

JP-A-6-335560 (paragraph 0106) JP-A-2005-131323 (paragraphs 0034, 0035, 0040, 0041, etc.)

  However, the slot machine of Patent Document 1 simply shifts to one type of RT triggered by the derivation of the RT symbol, and the control to the RT is monotonous. On the other hand, in the slot machine of Patent Document 2, the gaming state is controlled to RT when triggered by the derivation of the RT symbol in the normal gaming state, but a plurality of types of RTs having different advantages are triggered by the derivation of the RT symbol. It was possible to control either. However, which type of RT is assigned is determined by lottery, and there is only one type of RT symbol that allows the RT to control the gaming state. In other words, even if the player can intervene to control the gaming state to RT, the player cannot intervene until which type of RT is controlled, and the control to RT is monotonous. It was.

  The present invention makes it possible to intervene in which type of specific gaming state of a plurality of types of specific gaming states is selected by selecting a display result to be derived by the player to the variable display device by his / her own operation. An object of the present invention is to provide a slot machine that can improve the fun of games.

To achieve the above object, a slot machine according to the present invention includes:
A variable display device that allows a game to be started by setting a predetermined number of bets for one game using a gaming value (medal), and displays a plurality of types of identification information that can be distinguished from each other in a variable manner. In the slot machine (slot machine 1) in which one game is completed by the display result being derived to the (variable display device 2) and a winning can be generated according to the display result derived to the variable display device.
Whether to allow derivation of a plurality of types of winning display results including the first and second types of specific display results (replay B, replay C) before the display results of the variable display device are derived for each game. Pre-decision means (step S103) for determining
Stop operation means (stop buttons 12L, 12C, 12R) operated by the player to stop the variation display of the identification information, respectively;
Derivation control means (step S104) for causing the variable display device to derive a display result according to a determination result of the prior determination means and an operation procedure of the stop operation means,
The predetermining means permits the derivation of the first type of specific display result (Replay B) and the second type of specific display result (RT1) when the predetermined condition is satisfied. Including simultaneous determination means (FIG. 17 (b): replay B + replay C) for simultaneously determining in one game that the derivation of replay C) is permitted,
The derivation control unit is configured to determine whether the simultaneous determination unit simultaneously determines that the derivation of the first type of specific display result and the derivation of the second type of specific display result are permitted. 1 wherein when the stop operation manual stage is operated in step by deriving the specific display results of the first type, the first type of the specific display results when the stop operation means is operated by procedures other than said first procedure Other than the first procedure, the second type specific display result is derived when the stop operation means is operated in a second procedure different from the first procedure. Specific display result deriving means for deriving a display result other than the second type of specific display result when the stop operation means is operated (when the replay B winning flag and the replay C winning flag are set) For example, when the left stop button 12L is operated first, if the 12th to 19th symbols are positioned at the lower stage, the player will win the replay B and the symbols other than the 12th to 19th symbols If the timing is located in the lower stage, win a replay C),
The slot machine is
When the first type of specific display result is derived, the gaming state is controlled to the first type of specific gaming state (RT2) out of the specific gaming state different from the normal gaming state (normal gaming state, RT1). A first specific gaming state control means (step S609);
When the second type of specific display result is derived, the game state is controlled to a second type of specific game state (RT3) different from the first type of specific game state of the specific game state. 2 specific gaming state control means (step S611) ,
The pre-determining means includes a special display result with a transition to a special game state (regular bonus, big bonus) advantageous to a player different from the normal game state and the specific game state as the plurality of types of winning display results ( It is determined whether or not the derivation of the regular bonus, the big bonus (1), and the big bonus (2)) is permitted, and in the non-established state (normal game state, RT2, RT3) where the predetermined condition is not satisfied When it is determined that the derivation of the first type of specific display result and / or the second type of specific display result is permitted, it is also determined at the same time that the derivation of the special display result is permitted (FIG. 17B). : Normal game state, the number of judgment values of replay B + replay C in RT2, RT3 is 0)
It is characterized by that.

  In the above slot machine, in a game in which a predetermined condition is established, the fact that the derivation of the first type of specific display result is permitted and the derivation of the second type of specific display result is permitted in one game. Determined at the same time. In this case, if the player operates the stop operation means in the first procedure, the first type of specific display result can be derived, and if the stop operation means is operated in a second procedure different from the first procedure. The second type of specific display result can be derived. Then, depending on whether the first type specific display result is derived or the second type specific display result is derived, the game state is controlled to the first type specific game state and the second type specific game state, respectively. Can be.

Thus, in the established state, the player selects the first or second type of specific display result by selecting the operation procedure of the stop operation means, thereby selecting the first or second type. Since the player can intervene by his / her own operation to control the game state to an arbitrary state among the specific game states, the interest of the game can be improved. Also, depending on which of the first and second types of specific display results is derived as the display result of the variable display device, it is determined which of the first and second types of specific gaming state is controlled, so how It becomes easy for the player to determine whether the game state is to be controlled.
In addition, when the predetermined condition is not satisfied, one of the first and second types of specific display results is derived, and when the first and second types of specific game state are respectively controlled, Since the player can also expect that the derivation is permitted, the interest of the game can be further improved. Further, in a state where the predetermined condition is not satisfied, if it is not determined that the special display result is allowed to be derived, it is determined that the first and second types of specific display results are allowed to be derived. Therefore, even if it is not determined that the derivation of the special display result is permitted, the predetermined condition that the derivation of the first and second types of specific display results can be determined is satisfied. A feeling of scarcity can be given.

  In the established state, the probability that the simultaneous determination means simultaneously determines that the derivation of the first type of specific display result and the derivation of the second type of specific display result are allowed is the probability that It can be determined according to how the opportunity for a predetermined condition to be established is obtained. For example, when the predetermined condition is established only for the predetermined number of games after the end of the special gaming state advantageous to the player, the probability can be set higher than the reciprocal of the predetermined number of games.

  Moreover, the display mode of the first and second types of specific display results need not be one each. For example, when the display result A or the display result B is derived with the display result A and the display result B as the first type specific display result and the display result C as the second type specific display result, the first type specific game It is also possible to control the gaming state to the state, and to control the gaming state to the second type of specific gaming state when the display result C is derived.

  Further, in the case where the pre-determining means also determines whether or not to allow the derivation of the replay display result accompanied by the replay as the plurality of types of winning display results, the specific game state is, for example, The pre-determining means can be set to a re-game high probability state in which the probability of determining that the re-game display result is allowed to be derived is higher than the normal game state.

In the above slot machine,
In the first type of specific gaming state, at least the number of continuing games until the end may be different from that of the second type of specific gaming state (the number of continuing games for RT2 is 100 games and the number of continuing games for RT3) 150 games).

  In this case, whether the first type of specific display result is derived by operating the stop operation means in the first procedure, or whether the second type of specific display result is derived by operating the stop operation means in the second procedure Accordingly, the number of continued games in a specific gaming state to be controlled thereafter varies, and this is effective, for example, when the player wants to end the specific gaming state early in a time zone just before the closing of the gaming store. In particular, when the replay high probability state is applied as the specific game state, even if it is determined that the derivation of the special display result with the transition to the special game state advantageous to the player is permitted, the regame display If priority is given to the derivation of the result, it is difficult to derive the special display result, and this effect is produced.

  Further, the first type of specific gaming state is advantageous for the player (for example, when a high probability state of replaying is applied as the specific gaming state, the derivation of the regame display result is permitted by the predetermining means. The probability that the effect is determined) may be different from that of the second type of specific gaming state. The first and second types of specific gaming states may be different from each other in both the number of continuing games until the end and the advantage for the player.

  Here, when the number of continuing games until the end of the first and second types of specific gaming state and the advantage for the player are different, either one of the first or second type of specific gaming state is determined by the player. The specific gaming state with a high advantage for the player but with a small number of continuing games can be set as the specific gaming state with a low advantage for the player but with a large number of continuous games. In this case, the player can select whether to play a game in a specific game state with a high advantage even in a short period, or to play a game in a specific game state over a long period even if the advantage is slightly low, Gameability will be improved.

  In the above slot machine,
  The variable display device can display the identification information in a variable manner by rotating a reel on which a plurality of types of identification information that can be identified are arranged. In this case,
  The slot machine is
  A stepping motor that rotates the reel by exciting in a predetermined order with respect to a plurality of excitation phases arranged so as to surround a rotor incorporating a permanent magnet;
  Drive control means for performing drive control to excite the excitation phase of the stepping motor in the predetermined order;
  Data for performing operation by the microcomputer constituting the game control means including data necessary for specifying the stop phase, which is an excitation phase excited by the stepping motor when the reel is stopped, can be read and written. Data storage means having a storage area for storing, and capable of holding data stored in the storage area even when power supply to the slot machine is stopped;
  Deriving the winning display result including a ratio determined to permit the derivation of the first type of specific display result and / or the second type of specific display result based on an operation of a predetermined setting operation means. An allowable stage setting means for selecting and setting one of the allowable stages from a plurality of types of allowable stages having different ratios determined to be acceptable;
  Stored data determination means for determining whether or not the data stored in the data storage means is normal;
  Disabling means for disabling the progress of the game when the stored data determination means determines that the data stored in the data storage means is not normal;
  In a state where the progress of the game is disabled by the disabling means, the progress of the game is performed on the condition that the allowable stage is newly set by the allowable stage setting means based on the operation of the setting operation means. The disabling means for canceling the disabled state and allowing the game to proceed,
  A setting time initialization unit that initializes data stored in the data storage unit in association with a new allowable stage being set based on an operation of the predetermined setting operation unit;
  The derivation control means causes the drive control means to perform different drive control when the stop operation means is operated in the first procedure and when the stop operation means is operated in the second procedure. , Deriving the first type of specific display result or the second type of specific display result,
  The setting initialization means initializes at least data excluding data necessary for specifying the stop phase of the stepping motor among data stored in the data storage means,
  The drive control means includes data necessary for specifying the stop phase of the stepping motor stored in the data storage means when the data storage means is initialized by the setting time initialization means. Based on the above, it is possible to perform drive control of the stepping motor.

In the above slot machine,
The pre-determining means derives a specific end display result (single combination (modified)) in which the predetermined condition is not satisfied by being derived as a display result of the variable display device in the established state. ) Further including a specific end determination means for determining that the derivation of RT1 is permitted (RT1 ends with a winning of a single piece (modification)),
The derivation control means, when it is determined that the derivation of the specific end display result is permitted by the specific end determination means, the stop operation means in a specific end procedure at least partially overlapping with the first procedure. The specific end display result may be derived when the button is operated (when, for example, the left stop button 12L is operated first when the winning combination is one, the number 11 is displayed. If it is the timing when the symbol No. 20 is positioned in the lower row, a winning combination is won). In this case,
The first type of specific gaming state (RT2) may have a larger expected value for the number of acquired game values than the second type of specific gaming state (RT3) (FIG. 17B). ): RT2 has a higher probability of winning Replay A, and the medal payout rate is higher than RT3).

  In this case, the player operates the stop operation means in the first procedure so as to derive the first type special display result accompanied with the transition to the first type specific gaming state where the expected value of the number of acquired game values is large. Since the first procedure at least partially overlaps with the specific end procedure, it is determined that the derivation of the first and second types of specific display results is permitted. On the other hand, if it is determined that the derivation of the specific end display result is permitted, the state is not established. When the state is not established, the simultaneous determination means does not determine that the derivation of the first and second types of specific display results is permitted, and there is a chance that the first and second types of specific gaming states can control the gaming state. It will be lost.

  Thus, even if the risk of losing the chance of controlling the gaming state to the first and second specific gaming states is lost, the expected value of the number of game value acquisitions is high by operating the stop operation means in the first procedure. Challenge the control to the first type of specific gaming state, or avoid operating the stop operation means in the first procedure, and change to the second type of specific gaming state where the expected value of the number of game value acquisition is low The player will be given the option of taking safety measures to control. Thereby, gameability can be improved further.

  It is preferable that the specific end procedure completely includes the first procedure, and procedures other than the specific end procedure are completely included in the second procedure. In this case, there is no chance that the first type of specific display result can be derived while avoiding the derivation of the specific end display result, and the second type of specification can be avoided as long as the derivation of the specific display result is avoided. Since the display result can be derived, regardless of the skill of the player, the player is given the option of taking a risk measure or taking a safe measure.

In the above slot machine,
The pre-determining means is the first type of identification end result that is derived as a display result of the variable display device in the established state, and the predetermined condition is not established. A first specific end determination means (one combination A (modified example)) for determining that the derivation of the end display result is allowed, and a second type of specific display result different from the first type of specific end display result ( A second specific end determination means for determining that the derivation of the one-piece combination B (modified example) is permitted;
The derivation control means, when it is determined that the derivation of the first type of specific end display result is permitted, the stop operation means in a first specific end procedure at least partially overlapping with the first procedure. Is operated, the first type specific end display result is derived (for example, when the left stop button 12L is operated for the first time in the case where the single combination A is won, 11 The second procedure is performed when it is determined that the second type of specific end display result is allowed to be derived) if the symbols No. 20 to No. 20 are positioned at the lower stage, and a single winning combination is won. The second type of specific end display result can be derived when the stop operation means is operated in a second specific end procedure that overlaps at least partly. In this case,
The first type of specific gaming state (RT2) may have a larger expected value for the number of game value acquisitions than the second type of specific gaming state (RT3) (FIG. 17B). ): RT2 has a higher probability of winning Replay A, and the medal payout rate is higher than RT3)
The probability that the first specific end determination result is allowed to be derived by the first specific end determination means allows the second specific end determination result to be derived by the second specific end determination result. It can be higher than the probability that the effect is determined.

  In this case, when the stop operation means is operated in the first procedure, there is a high risk of losing the chance of controlling the gaming state to the first and second types of specific gaming state. High returns can be obtained if controlled to the state. On the other hand, when the stop operation means is operated in the second procedure, there is a low risk of losing the chance to control the gaming state to the first and second types of specific gaming state, but this controls to the second type of specific gaming state. You can get only a low return. In this way, the player is given the option of taking a high risk / high return measure or taking a low risk / low return measure. Thereby, gameability can be improved further.

The slot machine is
First electronic components (one-sheet BET switch 45, MAXBET switch 46, insertion medal sensor 44, start switch 41, stop switches 42L, 42C, 42R, reel sensors 3SL, 3SC, 3SR, A game electronic component including at least one of a payout sensor 81) and a second electronic component (reel motor 3ML, 3MC, 3MR, hopper motor 82) to which a signal related to the progress of the game is input;
The game electronic component is electrically connected, and a signal is input from the first electronic component and / or a signal is output to the second electronic component, thereby controlling at least the above-described game. A game control board (game control board 101) equipped with game control means (game control unit 110) including pre-determining means, the derivation control means and the specific game state control means;
The gaming electronic component and the game control board are detachable by connection between connectors (board side connector 620a and cable side connector 610a / board side connector 621a and cable side connector 611a / board side connector 622g and cable side connector 612g) And at least one wiring (cables 601a, 601g) for electrically connecting the gaming electronic component and the gaming control board;
A relay board (operation part relay board 107) connected at least between the wiring and the connector, and relaying signal input / output between the gaming electronic component and the game control board;
A connection release restriction state in which the connection between the connectors on the wiring between the gaming electronic component and the game control board is unreleasable unless the release restriction member related to the connection between the connectors is destroyed. Connection release restricting means (connector restricting members 500, 650) to be formed,
The disconnection restricting means includes
The connection of the wiring (cable 601a) between the game control board and the relay board (board side connector 620a and cable side connector 610a / board side connector 621a and cable side connector 611a) cannot be released. First disconnection restricting means (connector restricting member 500);
Second connection release restricting means (connector) that disables the connection between the connectors (board side connector 622g and cable side connector 612g) of the wiring (cable 601g) between the relay board and the gaming electronic component Restricting member 650).

  In this case, not only the wiring connector between the game control board and the relay board but also the release of the connection between the wiring connectors between the relay board and the game electronic component is regulated, The release of the connection between all the connectors of the wiring provided between the electronic component for use and the game control board is regulated. As a result, it is difficult to perform any illegal act such as illegally inputting a signal related to the progress of the game to the game control board by replacing any connector with a connector such as an unauthorized driving tool, etc. Implementation etc. can be effectively prevented.

  In addition, since the connection release restriction state is formed by the connection release restriction means, in order to release the connection between the connectors, the release restriction member must be destroyed, thereby releasing the connection again after releasing the connection. Since it becomes extremely difficult to form a restricted state and takes time and effort, it is possible to more effectively suppress the cheating. Further, since the connection release restricting means includes the second connection release restricting means that makes it impossible to release the connection between the connectors of the wiring between the relay board and the game electronic component, illegal connection to the game electronic component is prevented. Signal input / output can also be prevented.

  Note that one or more relay boards may be connected between one game electronic component and the game control board. When a plurality of relay boards are connected, the connection release restricting means includes: It is preferable to include a third release restricting means for disabling the connection between the connectors of the wiring between one relay board and another relay board, and in this way, the electronic component for gaming And the release of connection between all connectors of the wiring provided between the game control board and the game control board are restricted.

  The stop buttons 12L, 12C, and 12R are buttons that the player operates to stop the rotation of the reels 3L, 3C, and 3R at a desired timing, respectively, and the operations are stop switches 42L, 42C, and 42R (see FIG. 3). Is detected, the rotation of the reels 3L, 3C, 3R is stopped. The maximum stop delay time from the operation of the stop buttons 12L, 12C, 12R to the stop of rotation of the corresponding reels 3L, 3C, 3R is 190 milliseconds.

  The reels 3L, 3C and 3R rotate 80 times per minute and change the design of 80 x 21 (number of symbols per reel) = 1680 frames, so a maximum of 4 symbols in 190 milliseconds Can be pulled in. That is, the stop symbols selected by the stop control table described later are the symbols displayed when the stop buttons 12L, 12C, and 12R are operated, and the symbols that are four frames ahead of them, for a total of five frames. It is a design.

  Further, a panel that covers the stop buttons 12L, 12C, and 12R is applied as the bonus notification section 36. The bonus notification unit 36 notifies the player that the bonus notification lamp 66 (see FIG. 3) is turned on, so that a regular bonus winning and a big bonus winning described later can be made. Further, on the right side of the stop button 12R, there is provided a medal clogging elimination button 18 that mechanically vibrates the slot machine 1 when a medal is jammed.

  On the lower front side of the slot machine 1, a medal payout port 71 and a medal storage tray 72 are provided. The medal payout port 71 discharges medals paid out by the hopper 80 (see FIG. 3) to the outside. The medal storage tray 72 is for storing paid-out medals. The front panel on the medal storage tray 72 is irradiated with light emitted from the fluorescent lamp 6 (see FIG. 3) installed therein.

  Speakers 7U, 7L, and 7R are provided as rendering means on the lower front side of the slot machine 1 and on the left and right sides of the upper front side, respectively. The speakers 7U, 7L, and 7R continuously output unique sound effects (music) in a gaming state advantageous to the player such as a big bonus and a regular bonus described later. In addition, a predetermined sound effect is output when the start lever 11 and the stop buttons 12L, 12C, and 12R are operated or when winning a prize. Furthermore, an alarm sound is output when an error occurs, when the front door is released, when a set value is changed, and when the number of bets and credits is settled, and various effect sounds according to the gaming state are output.

  Further, on the front side of the slot machine 1, an effect by light is performed by light emission of game effect lamps 75 </ b> A to 75 </ b> M (see FIG. 3) as effect means so as to surround the variable display device 2 and the liquid crystal display 4. Game effect display sections 5A to 5M are provided. The game effect display units 5A to 5M perform effects by light in various patterns according to the progress of the game. Note that the light emission colors of the game effect display units 5A to 5M may be either single colors or multiple colors.

  FIG. 3 is a diagram showing the configuration of the control circuit of the slot machine 1. As shown in the figure, the control circuit of the slot machine 1 includes a power supply board 100, a game control board 101, an effect control board 102, a reel relay board 103, a reel lamp relay board 104, an external output board 105, and an effect relay board 106. It is divided roughly.

  The power supply board 100 transforms an external power supply voltage of AC 100V and supplies operating power to the game control board 101 and other parts of the slot machine 1. In FIG. 3, it is shown that only the game control board 101, the hopper 80, and each of the switches 91 to 94 are connected, but the power supply board 100 also supplies power to other parts. The power supply board 100 is provided in the slot machine 1 and is connected to a hopper 80 that includes a hopper motor 82 that performs a medal payout operation and a payout sensor 81 that detects a medal payout operation.

  The power supply board 100 sets a winning probability for an internal lottery to be described later, and a setting switch 91 for changing a setting value (setting 1 to setting 6) of a virtual medal payout rate calculated based on the probability. The switch 91 is also connected to a setting key switch 92 for enabling the operation, a second reset switch 93 for resetting the internal state (RAM 112), and a main switch 94 for switching the power ON / OFF. A detection signal is sent to the game control board 101. These switches 91 to 94 are provided inside the slot machine 1.

  The game control board 101 is a control board on the main side that controls the overall flow of the game in the slot machine 1, and includes a control unit 110 including a CPU 111, a RAM 112, a ROM 113, and an I / O port 114. It is installed. Further, a random number generation circuit 115, a sampling circuit 116, a power supply monitoring circuit 117, a reset circuit 118, and other circuits are mounted.

  The CPU 111 has an interrupt function (including an interrupt prohibition function) such as a timekeeping function and a timer interrupt, and executes a program (described later) stored in the ROM 113 to perform processing related to the progress of the game, and in the slot machine 1 Control each part of the control circuit directly or indirectly. The processing word of the CPU 111 is 1 byte, and the addresses of the RAM 112 and the ROM 113 are assigned in units of 1 byte.

  The RAM 112 is used as a work area when the CPU 111 executes a program. The RAM 112 is backed up by a battery and retains stored contents even when the slot machine 1 is turned off. The RAM 112 is provided with an area for a counter that counts the number of steps of the stepping motors that respectively constitute the reel motors 3ML, 3MC, and 3MR. Data relating to the number of credits is stored in the RAM 112. The ROM 113 stores programs executed by the CPU 111 and fixed data. The I / O port 114 inputs and outputs control signals to and from each circuit connected to the game control board 101.

  The random number generation circuit 115 is configured by a counter that counts up and updates a value every time a pulse is generated, and the sampling circuit 116 acquires a numerical value counted by the random number generation circuit 115. The random number generation circuit 115 is provided for each type of random number used for the progress of the game, and a range of numerical values to be counted for each type of random number is determined. The CPU 111 sends an instruction to the sampling circuit 116 according to the processing to acquire the numerical value indicated by the random number generation circuit 115 as a random number (hereinafter, this function is referred to as a hardware random number function).

  The power monitoring circuit 117 monitors the power supply voltage supplied from the power supply substrate 100, and outputs a voltage drop signal to the control unit 110 when detecting a voltage drop. Although not particularly shown, the control unit 110 includes an interrupt input terminal connected to the power supply monitoring circuit 117, and an external interrupt is generated in the CPU 111 when a voltage drop signal is input to the interrupt input terminal. The CPU 111 executes a power interruption interrupt process.

  The reset circuit 118 outputs a reset signal when the voltage rises to a level at which the control unit 110 can be activated when the power is turned on to start the control unit 110, and generates a signal periodically output from the control unit 110. When the count is incremented without being cleared based on the reset counter, that is, when the control unit 110 does not operate for a certain time, a reset signal is output to the control unit 110 and the control unit 110 is restarted. .

  The CPU 111 also has a function of updating the numerical value of the specific address in the RAM 112 by timer interrupt processing and acquiring the updated numerical value as a random number (hereinafter, this function is referred to as a software random number function). The CPU 111 transmits various commands to the effect control board 102 via the I / O port 114. Note that information (commands) is sent from the game control board 101 to the effect control board 102 only in one direction, and no information (commands) is sent from the effect control board 102 to the game control board 101.

  The command transmitted from the game control board 101 to the effect control board 102 is composed of 2 bytes, the upper 1 byte is control information indicating the type of command, and the lower 1 byte is information indicating the contents of the control state. When transmitting a command from the game control board 101 to the effect control board 102, the CPU 111 sets a command to be transmitted in a command transmission buffer provided in the RAM 112 in the order of upper byte and lower byte.

  Since the CPU 111 needs to transmit a plurality of commands to the effect control board 102 at the same time in some cases, the command transmission buffer of the RAM 112 has a capacity sufficient to set a predetermined number of commands. For example, when two commands are transmitted at the same time, the upper byte and lower byte of the first command, the upper byte and lower byte of the second command, etc. are set in the command transmission buffer of the RAM 112. The upper byte and lower byte of each command set in the command transmission buffer are sent from the I / O port 114 to the effect control board 102 in byte units.

  Connected to the game control board 101 are a single BET switch 45, a MAXBET switch 46, a start switch 41, stop switches 42L, 42C, 42R, a settlement switch 47, a first reset switch 48, and a throw-in medal sensor 44. Detection signals from the switches / sensors are input. In addition, detection signals of the reel sensors 3SL, 3SC, and 3SR are input via the reel relay substrate 103. In accordance with the detection signals of these switches / sensors input via the I / O port 114 or the detection signals of various switches input via the power supply board 100 as described above, the CPU 111 on the game control board 101 Processing is in progress.

  The game control board 101 also includes a flow path switching solenoid 49, a game number display 51, a credit display 52, a payout display 53, a loading instruction lamp 59, a single betting lamp 54, two betting lamps 55, 56, Three betting lamps 57 and 58, a game over lamp 63, a start lamp 60, a replay lamp 62, BET button lamps 70a and 70b, and operation valid lamps 63L, 63C, and 63R are connected, and the CPU 111 follows the progress of the game. These operations are controlled.

  The game control board 101 is connected to reel motors 3ML, 3MC, and 3MR via a reel relay board 103. The CPU 111 refers to a stop control table selected according to a winning flag set in the RAM 112 by internal lottery, which will be described later, and controls the reel motors 3ML, 3MC, 3MR via the reel relay board 103 to thereby control the reels 3L, 3C. 3R is stopped. An effect control board 102 is further connected to the game control board 101 via an effect relay board 106.

  The effect relay board 106 is a board provided to ensure one-way information transmitted from the game control board 101 to the effect control board 102. The effect relay board 106 does not check the game control board 101 and the effect control board 102 by checking this state, and an illegal signal (especially an external input to the effect control board 102 is input to the control unit 110 of the game control board 101). It is possible to check whether or not a modification has been made such that a signal is input).

  The effect control board 102 is a sub-side control board that controls the execution of effects in the slot machine 1, and is equipped with a control unit 120 including a one-chip microcomputer including a CPU 121, a RAM 122, a ROM 123, and an I / O port 124. Yes. Further, the random number generation circuit 125, the sampling circuit 126, and the sound processing unit (SDP) 127 are mounted, and the CPU 121 acquires the value counted by the random number generation circuit 125 by the sampling circuit 126, thereby controlling the game. A hardware random number function similar to that of the substrate 101 is formed. It also has a software random number function by interrupt processing.

  The CPU 121 executes a program (described later) stored in the ROM 123 to perform processing related to the execution of the effect, and controls each circuit in the effect control board 102 and each circuit connected thereto. The RAM 122 is used as a work area when the CPU 121 executes a program. The RAM 122 is also battery-backed up, and retains the stored contents even when the slot machine 1 is turned off. The ROM 123 stores programs executed by the CPU 121 and fixed data. The I / O port 124 inputs and outputs control signals to and from each circuit connected to the effect control board 102.

  The execution of the effect by the CPU 121 is performed based on a command received from the game control board 101 via the I / O port 124. When a command transmitted from the game control board 101 arrives at the I / O port 124, a command reception interrupt is generated for the CPU 121, and the received command is sequentially placed in the command reception buffer of the RAM 122 by this command reception interrupt processing. To go. The CPU 121 retrieves the command stored in the command reception buffer in units of 2 bytes, and performs processing by determining the command type in the upper byte and the content indicated by the command in the lower byte.

  When a plurality of commands are transmitted from the game control board 101 at the same time, the CPU 121 cannot naturally process the plurality of commands at the same time. For this reason, the command reception buffer of the RAM 122 has a capacity enough to store a plurality of commands, and the CPU 121 has received another command when processing based on one command extracted from the command reception buffer is completed. If it is in the buffer, the processing based on the next command is performed. Note that the capacity of the command reception buffer in the RAM 122 is larger than the capacity of the command transmission buffer in the RAM 112.

  The effect control board 102 is connected with game effect lamps 75A to 75M, a liquid crystal display 4, speakers 7L, 7R, and 7U, a fluorescent lamp 6, a weight lamp 61, and a bonus notification lamp 66. A reel lamp 3LP is connected via a reel lamp relay substrate 104. The control unit 120 of the effect control board 102 performs these effects by controlling these parts.

  The reel relay board 103 relays between the game control board 101, the external output board 105 and the reel unit 3. The reel lamp relay board 104 relays between the effect control board 102 and the reel unit 3. The reel relay substrate 103 is also connected with a full sensor 90, and its detection signal is input. The full tank sensor 90 is provided inside the slot machine 1 and detects that the medals in the overflow tank storing the medals overflowed from the hopper 80 are full.

  When a full tank is detected by the full tank sensor 90, a full tank error occurs. Note that whether or not a full tank is detected by the full sensor 90 can be checked once per game, for example, at a timing when the number of bets is fixed. However, when the player has won Replay A, Replay B or Replay C in the previous game, it is not checked whether the full tank sensor 90 has detected a full tank.

  The external output board 105 is connected to an external device such as a hall management computer and receives a big bonus medium signal, regular bonus medium signal, reel control signal, stop signal input from the game control board 101 via the reel relay board 103. The switch signal, medal IN signal, medal OUT signal, winning status signal, and security signal are output to the external device. The big bonus medium signal, regular bonus medium signal, reel control signal, stop switch signal, medal IN signal, medal OUT signal, winning status signal, and security signal are output from individual output terminals. Of course, the security signal includes a door opening signal, a set value change signal, a closing error signal, a payout error signal, another error signal, and a settlement in progress signal as described later. Output from the output terminal.

  The external output board 105 is equipped with a door opening sensor 95 that detects that the front door is in an open state, and a door opening signal of the security signal is output based on a detection signal of the door opening sensor 95. . The external output board 105 stores electricity when power is supplied to the slot machine 1 (that is, when the slot machine 1 is ON) and also when power supply is interrupted (that is, the slot machine 1). A backup power source constituted by a storage battery that supplies the stored electric power to the external output board 105 when 1 is OFF) is mounted.

  When the power of the slot machine 1 is ON, the external output board 105 detects that the front door is open by the door open sensor 95 by supplying power from the power supply board 101, and the front door is opened. A security signal including a door opening signal indicating the presence is output to the external device. On the other hand, when the power of the slot machine 1 is turned off, the external output board 105 is supplied with power from this backup power supply, detects that the front door is open by the door open sensor 95, and the front door is open. A security signal including a door opening signal indicating that the device is in the state is output to the external device. Details of the medal IN signal and medal OUT signal output from the external output board 105 and the security signal will be described later.

  Next, stepping motors constituting the reel motors 3ML, 3MC, 3MR will be described. The stepping motor that constitutes each of the reel motors 3ML, 3MC, and 3MR is, for example, a hybrid type stepping motor, and includes a stator and a rotor facing the stator. The rotor has a large number of gear-like projections, and permanent magnets magnetized in the same direction as the rotation shaft are incorporated therein.

  The stepping motor receives a pulse signal (excitation pulse) from the CPU 111 of the game control board 101, an excitation current sequentially flows through each of the excitation phases φ1 to φ4 of the stator, and these excitation phases φ1 to φ4 are excited in a predetermined order. Thus, the rotor is rotationally driven, and the reels 3L, 3C, and 3R are rotated by the rotation of the rotation shaft. As a control method for rotationally driving the stepping motor, for example, a 1-2 phase excitation method is applied. In the 1-2 phase excitation method, the excitation phases for inputting a pulse signal among the excitation phases φ1 to φ4 are (φ1, φ2), (φ1), (φ4, φ1), (φ4), (φ3, φ4), (Φ3), (φ2, φ3), (φ2), (φ1, φ2)... Are sequentially switched, and the excitation phase for inputting the pulse signal is alternately switched to one phase or two phases. Yes.

  Thus, each time a pulse signal for applying an excitation current to the excitation phases φ1 to φ4 is input, the rotation shaft of the stepping motor rotates one step at a time. The rotation step of the stepping motor is counted by a counter provided in the RAM 112 for each of the reel motors 3ML, 3MC, and 3MR. Then, it is understood how to switch the excitation phase of the pulse signal input according to the counted stepping motor rotation step.

  Further, when the reference position is detected by the reel sensors 3SL, 3SC, 3SR as the reels 3L, 3C, 3R rotate, the counter value is cleared. Therefore, the rotation angles of the reel motors 3ML, 3MC, and 3MR, that is, the symbol positions of the reels 3L, 3C, and 3R can be understood by referring to the counter value (number of steps) counted by the rotation step.

  When stopping the rotation of the stepping motor, the rotor is suddenly braked by two-phase excitation control, which will be described in detail later, in accordance with the target stop position, and then the rotor is stopped by three-phase excitation control, which will be described later. This stops the rotation of the reels 3L, 3C, and 3R that are integrally coupled to the rotors of the reel motors 3ML, 3MC, and 3MR.

  FIG. 4 is a schematic diagram showing a wiring connection state between the game control board 101 and the game electronic components connected to the game control board 101. FIG. 4 shows a single BET switch 45, a MAXBET switch 46, which is operated when setting a bet number among various electronic components such as various switches and sensors connected to the game control board 101, and when starting a game. A start switch 41 that is operated, stop switches 42L, 42C, and 42R that are operated when the rotation of the reels 3L, 3C, and 3R is stopped, a inserted medal sensor 44 that detects a medal inserted to set the bet number, Reel motors 3ML, 3MC, 3MR for rotating the reels 3L, 3C, 3R, reel sensors 3SL, 3SC, 3SR for detecting the rotation of the reels 3L, 3C, 3R, and detection of medals to be paid out when a winning occurs The payout sensor 81 and the effect control board 102 are shown, and other switches, sensors, etc. are not shown. .

  The game electronic components 45, 46, 41, 42L, 42C, 42R, 44, 3SL, 3SC, 3SR, 3ML, 3MC, 3MR, 82, 81 except for the effect control board 102 are used for playing signals related to the progress of the game. It is an electronic component that inputs and outputs to the control board 101. The signal related to the progress of the game is, for example, an operation for setting the number of bets to make the game startable, an operation for starting the game, or an operation for deriving the display results of the reels 3L, 3C, 3R. Such as signals output to the game control board 101 in accordance with the progress operation of the game, detection of inserted medals, detection of the reference position of the reels, detection of the payout medals, etc., output from the game electronic components according to the progress of the game In order to drive the signal input to the game control board 101, the drive signal for driving the reels 3L, 3C, 3R in response to the detection of the start operation, and the hopper 80 for paying out medals when a winning is generated. And a signal output from the game control board 101 in accordance with the progress of the game and input to the game electronic component.

  These gaming electronic components 45, 46, 41, 42L, 42C, 42R, 44, 3SL, 3SC, 3SR, 3ML, 3MC, 3MR, 82, 81 are sent to the game control board 101 as the game progresses. And a second electronic component to which a signal from the game control board 101 is input as the game progresses.

  Specifically, the single bet switch 45, the MAXBET switch 46, which are operated when setting the bet number, and the inserted medal sensor 44 which detects a medal inserted to set the bet number, It is a first electronic component that outputs a BET signal to the game control board 101 based on the detection. Since the game control unit 110 performs a bet number setting process based on reception of the BET signal, the bet number cannot be set without these electronic components. That is, since the game cannot be started unless the bet number is set, the one-sheet BET switch 45, the MAXBET switch 46, and the inserted medal sensor 44 are game electronic components necessary for the progress of the game.

  A start switch 41 that detects an operation for starting a game is a first electronic component that outputs a start signal to the game control board 101 based on the detection of the operation. The game control unit 110 performs a process of starting a game (reel rotation process or the like) based on the reception of the start signal. Therefore, the game cannot be started without this electronic component. That is, the start switch 41 is a game electronic component necessary for the progress of the game.

  Stop switches 42L, 42C, and 42R that detect operations for deriving the display results of the reels 3L, 3C, and 3R are first electronic components that output a stop signal to the game control board 101 based on the detection of the operations. is there. Since the game control unit 110 performs a process of deriving a display result by stopping the rotation of the corresponding reels 3L, 3C, and 3R based on the reception of the stop signal, the reels 3L, 3C, and 3R do not have this electronic component. The display result of cannot be derived. That is, the stop switches 42L, 42C, and 42R are game electronic components necessary for the progress of the game.

  The reel sensors 3SL, 3SC, and 3SR that detect the rotation of the reels 3L, 3C, and 3R are first electronic components that output a detection signal for the reference position of the reel to the game control board 101. The game control unit 110 does not have this electronic component because it performs processing to stop the rotation by grasping the positions of the symbols of the corresponding reels 3L, 3C, and 3R based on reception of the detection signal of the reference position of the reels. In addition, derivation of display results of each reel 3L, 3C, 3R, determination of winning, etc. cannot be performed. That is, the reel sensors 3SL, 3SC, 3SR are game electronic components necessary for the progress of the game.

  A payout sensor 81 that detects medals to be paid out when a winning is generated is a first electronic component that outputs a medal payout signal to the game control board 101 based on the detection of the medals. The game control unit 110 performs payout processing for paying out the number of medals corresponding to the generated winning based on the reception of the payout medal detection signal, and therefore, the number of medals corresponding to the generated winning without this electronic component. Cannot be paid out. That is, the payout sensor 81 is a game electronic component necessary for the progress of the game.

  The reel motors 3ML, 3MC, and 3MR that rotate the reels 3L, 3C, and 3R are second electronic components to which a drive signal output from the game control board 101 is input. The reel motors 3ML, 3MC, and 3MR rotate the reels 3L, 3C, and 3R based on the input of the drive signal output from the game control board 101, and start the symbol variation display. Even if the reels 3L, 3C, and 3R are not actually rotated based on the above, the game control unit 110 receives the signals from the reel sensors 3SL, 3SC, and 3SR after outputting the reel drive signal. The game can be controlled to proceed as the reel rotates. However, the timing at which signals are input to the game control board 101 from the reel sensors 3SL, 3SC, and 3SR is an error unless the reel drive signal is output. In order to measure the output timing of a signal based on the detection of rotation, a reel drive signal is required. That is, the reel motors 3ML, 3MC, and 3MR are game electronic components necessary for the progress of the game.

  The hopper motor 82 that drives the hopper tank that pays out medals is a second electronic component that receives a drive signal output from the game control board 101 in response to the occurrence of a prize. The hopper motor 82 drives the hopper 80 based on the input of the drive signal output from the game control board 101 to pay out medals, but does not actually drive the hopper 80 based on the signal input. Even if the game control unit 110 outputs the drive signal of the hopper 80, the game control unit 110 can control to advance the game as a medal is paid out by inputting the signal from the payout sensor 81. it can. However, since the timing at which a signal is input from the payout sensor 81 to the game control board 101 is an error unless the drive signal of the hopper 80 is output, the payout medal is detected when the game is advanced by a driving tool. In order to measure the output timing of the signal based on this, a driving signal for the hopper tank is required. That is, the hopper motor 82 is a game electronic component necessary for the progress of the game.

  Also, these gaming electronic components 45, 46, 41, 42L, 42C, 42R, 44, 3SL, 3SC, 3SR, 3ML, 3MC, 3MR, 82, 81 are basically common to multiple models. Since it is an electronic component to be used and there is little opportunity to remove and replace it from the main body unless a failure or the like occurs, it is fixed at a predetermined position of the main body of the slot machine. On the other hand, the game control board 101, the effect control board 102, and the like need to be replaced when changing the model, and are removed from the main body at that time.

  That is, when removing the game control board 101, the connection with the game electronic components 45, 46, 41, 42L, 42C, 42R, 44, 3SL, 3SC, 3SR, 3ML, 3MC, 3MR, 82, 81 is released. Because it is necessary, gaming electronic components 45, 46, 41, 42L, 42C, 42R, 44, 3SL, 3SC, 3SR, 3ML, 3MC, 3MR, 82, 81 and game control board 101 are relay boards 100, 103 , 106, 107, and the boards and the board and the game electronic component are connected via a cable. The cable and the board are electrically connected by connecting a cable side connector provided at an end of the cable and a board side connector electrically connected to the wiring pattern of the board.

  First, the first electronic component will be described in detail. One of the BET switch 45, the MAXBET switch 46 or the inserted medal sensor 44 and the cable control board 101 provided with the game control board 101 is driven into any connector. If the BET signal is illegally output from the driving tool to the game control board 101, the bet number may be set even though the bet number setting operation is not performed. When a connector of a driving tool is connected to one of the connectors of a cable provided between the start switch 41 and the game control board 101, and a start signal is illegally output from the driving tool to the game control board 101 There is a possibility that the game is started without performing the game start operation. The connector of the driving tool is connected to one of the connectors of the cable provided between the stop switches 42L, 42C, 42R and the game control board 101, and the stop signal is illegally transmitted from the driving tool to the game control board 101. If output, the rotation of the reel may be stopped without performing a stop operation.

  The connector of the driving tool is connected to one of the connectors of the cable provided between the reel sensors 3SL, 3SC, 3SR and the game control board 101, and the reel rotation signal is illegal from the driving tool to the game control board 101. Is output, the display results of the reels 3L, 3C, and 3R may be derived and winning decisions may be performed without rotating the reels. The connector of the driving tool is connected to one of the connectors of the cable provided between the payout sensor 81 and the game control board 101, and a medal payout signal is illegally output from the driving tool to the game control board 101. There is a possibility that the medals are counted without paying out medals.

  The second electronic component will be described in detail. The game control board 101 is released by disconnecting any one of the cable connectors provided between the reel motors 3ML, 3MC, and 3MR and the game control board 101. When the driving signal output from the game control board 101 can be acquired by the driving tool, the timing at which the driving signal of the reel is output from the game control board 101 can be specified on the driving tool side, so that the game control is originally performed from the reel sensors 3SL, 3SC, 3SR. There is a possibility that the reel rotation detection signal input to the substrate 101 may be output from the driving tool at an appropriate timing after the reel rotation.

  In addition, the drive signal output from the game control board 101 can be acquired by a driving tool or the like after the connection at any of the connectors of the cable provided between the hopper motor 82 and the game control board 101 is released. Then, since the timing at which the driving signal of the hopper tank is output from the game control board 101 can be specified on the driving instrument side, the payout medal detection signal originally input from the payout sensor 81 to the game control board 101 is sent from the driving instrument to the hopper tank. May be output at an appropriate timing after driving.

  As described above, the first electronic components 45, 46, 41, 42L, 42C, 42R, 44, 3SL, 3SC, 3SR, 81 are output according to the progress of the game. When a signal to be played is output from the driving tool, the game control unit 110 can perform control to advance the game based on reception of the signal. On the other hand, when a signal that is output from the game control board 101 according to the progress of the game and is originally input to the second electronic components 3ML, 3MC, 3MR, 82 is input to the driving tool, When the game control unit 110 can specify the output timing of a signal output after driving the reel motors 3ML, 3MC, 3ML and the hopper motor 82, a new signal is input to the main control board 101 based on this. Since the game control unit 110 can perform control to advance the game based on the reception of the signal, there is a risk that an illegal act such as automatically progressing the game may be performed. In the slot machine 1 according to this embodiment, various measures are taken to prevent frauds due to the connection of a driving tool, as will be described later.

  Next, a configuration around the power source to the game control unit 110 in the game control board 101 will be described. FIG. 5 is a circuit diagram showing a backup power supply line for the game control unit 110.

The game control board 101 is supplied with a + 5V DC voltage generated by the voltage generation circuit of the power supply board 100. The + 5V DC voltage supplied from the power supply board 100 is supplied to the V _DD input terminal as a driving power supply for the game control unit 110, and also branches on the game control board 101 as shown in FIG. _BB ) DC voltage supply line is formed. The +5 V (V _BB ) DC voltage supply line is connected to the memory backup power input terminal V _BB of the game control unit 110 via the backflow prevention diode 312 and is connected to the ground on the power supply board 100 side. A capacitor (not shown) having a large capacity is provided between them. As a result, a DC voltage of +5 V (V _BB ) can be stored in the capacitor, and when the power supply to the slot machine 1 is interrupted, the voltage stored in the capacitor is stored in the RAM 112 in the game control unit 110. It can be supplied as a backup power source.

Further, the + 5V (V _BB ) DC voltage supply line is not directly connected to the memory backup power input terminal V _BB of the game control unit 110 on the game control board 101, but as shown in FIG. Via the cable 600a for wiring connection between the game control board 101 and the operation part relay board 107, the operation part relay board 107, the cable 601g for wiring connection between the operation part relay board 107 and the insertion medal sensor 44, and the insertion medal sensor 44 folded back, cable 601g, the operation unit relay board 107 is connected to the game control board 101 again via the cable 600a, and is connected to a memory backup power input terminal _{V BB} gaming controller 110. That is, when the power supply to the slot machine 1 is cut off, the voltage accumulated in the capacitor is changed from the game control board 101 to the cable 600a-operation part relay board 107-cable 601g-inserted medal sensor 44-cable 601g-operation part. After passing through the relay board 107-cable 600a, it is supplied to the game control unit 110, and the storage state of the RAM 112 in the game control unit 110 is maintained.

  Therefore, in a state where the power supply to the slot machine 1 is cut off, the connection between the board-side connector 620a of the game control board 101 and the cable-side connector 610a of the cable 600a, the cable-side connector 611a of the cable 600a and the operation unit relay board The connection line of the backup power supply is disconnected by releasing any of the connection between the board side connector 621a of the board 107 and the board side connector 622g of the operation unit relay board 107 and the cable side connector 612g of the cable 601g. As a result, the data in the RAM 112 of the game control unit 110 cannot be held and will be lost. That is, when even one connection between the game control board 101 and the inserted medal sensor 44 is released, the backup data held in the RAM 112 of the game control unit 110 is lost.

  In the slot machine 1 according to this embodiment, it is difficult to connect the driving tool by restricting the release of the connector connection between the game control board 101 and the game electronic component. Specifically, the connector connection between the game control board 101 and the inserted medal sensor 44, that is, the connection between the board side connector 620a of the game control board 101 and the cable side connector 610a of the cable 600a, the cable side connector 611a of the cable 600a. And the connection between the board-side connector 621a of the operation unit relay board 107 and the connection between the board-side connector 622g of the operation part relay board 107 and the cable-side connector 612g of the cable 601g are restricted from being released from each other. The connection between the board side connector 620a and the cable side connector 610a is restricted by the connector restricting member 500, the connection between the cable side connector 611a and the board side connector 621a, and the connection between the board side connector 622g and the cable side connector 612g. The release of the connection is regulated by the connector regulating member 650.

  Next, the configuration of the external output board 105, the medal IN signal and the medal OUT signal output from the external output board 105, and the security signal will be described in detail. The external output board 105 does not output a medal IN signal every time a medal is inserted from the medal insertion slot 13 or each time the single BET button 14 or the MAXBET button 15 is operated, but when the start lever 11 is operated. The medal IN signal is output collectively. On the other hand, the medal OUT signal is output every time one medal is paid out from the hopper 80.

  FIG. 6 is a diagram showing an output format of a security signal output from the external output board 105. As described above, the security signal is for outputting a plurality of types of signals from the same external output terminal. As shown in the figure, the security signal is time-divided every Xms (where X is an arbitrary number), and one frame period. Is output as 14Xms.

  The first Xms period in one frame period is a period for outputting a start bit, the last 6 Xms period is a blank period, and the Xms period immediately before the blank period is a period for outputting a stop bit. In the period of 6Xms, time-division is performed every Xms period, and 6 types of signals are output: door open signal, set value change signal, closing error signal, payout error signal, other error signal, and adjusting signal. It has become a thing.

  The door open signal is a signal indicating that the front door is open when it is in the ON state, and the setting key switch 92, the setting switch 91, or the various boards 101 to 106 and the cable connecting the boards are slot machines. Since it is installed inside the front door of 1 open, it is output because there is a possibility of fraud when the front door is open. The set value change signal is a signal indicating that the set value has been changed in the ON state, and the change of the set value is fraudulent because it directly affects the payout rate of medals. It is output because there is a possibility of being.

  The insertion error signal is a signal that indicates that an error has occurred in the insertion of a medal when it is in the ON state and has not yet been restored. Is output because there is a possibility that a credit is filled using an unauthorized device without inserting medals). The payout error signal is a signal indicating that an error has occurred in paying out medals when it is in the ON state and has not yet returned. When a payout error occurs, an illegal act such as removing a medal from the hopper 80 is performed. It is output because there is a possibility that it has been done.

  The other error signal is a signal indicating that an error other than the input error and the payout error has occurred in the ON state and has not yet been recovered. Errors other than throw-in errors and payout errors do not occur in an attempt to increase medals directly, but some sort of fraud may occur at the time of error occurrence. Another error signal is output. The payment in progress signal is a signal indicating that the medal is being settled when it is in the ON state, and although the medals are not necessarily fraudulent, it is an action that is normally performed, but it is illegal if this is done frequently. It is output because there is a possibility that various actions are being performed.

  The start bit is always in the ON state, and the stop bit and the blank period are always in the OFF state. There are six types of signals indicating the actual contents as security signals: door open signal, set value change signal, input error signal, payout error signal, other error signal, and adjustment signal. In this case, since the period in which the security signal is OFF continues only for 6Xms, it can be determined that the period of Xms in which the security signal is in the ON state after being in the OFF state for 7Xms or more is the start bit period. it can.

  The security signal output from the external output board 105 is a serial output of a door opening signal, a set value change signal, a closing error signal, a payout error signal, another error signal, and a settlement signal. A predetermined output terminal board is provided between the external output board 105 and an external device such as a hall management computer, a serial door opening signal, a set value change signal, a closing error signal, a payout error signal, other error signals, In addition, the adjustment signal may be converted into parallel and output to an external device.

The locking grooves 514 and 514 formed in the 513a are provided at positions that engage with the shallow groove portions 514a and 514a.

  Next, the state of attachment of the connector restricting member 500 to the board case 200 and the state of attachment of the board case 200 to the housing will be described.

  First, the game control board 101 is accommodated in the lower case 201 and the upper case 203 constituting the board case 200, and the board case 200 is sealed. In order to seal the lower case 201 and the upper case 203, the engaging portions 230 of the corresponding upper case 203 are engaged with the two pairs of locking portions 210 of the lower case 201, respectively, One of the sealing pieces 211 of the case 201 and the corresponding sealing piece 231 of the upper case 203 are fixed with a one-way screw.

  As is well known, a one-way screw can be screwed by rotation in one direction, but cannot be rotated even if it is rotated in the other direction, that is, the screw cannot be loosened. It is a screw. For this reason, when one sealing piece 211 of the lower case 201 and the corresponding sealing piece 231 of the upper case 203 are fixed with a one-way screw, either the sealing piece 211 or the sealing piece 231 is broken. Without this, these sticking cannot be released.

  Then, by fixing the sealing piece 211 and the sealing piece 231, the longitudinal movement of the upper case 203 with respect to the lower case 201 is restricted, and as a result, the upper case 203 is engaged with the locking portion 210 of the lower case 201. The release of the engagement of the joint portion 230 is also restricted, and the upper case 201 and the lower case 203 are integrated with the game control board 101 accommodated therein, and the sealing piece 211 and the sealing piece 231 are broken. Otherwise, it will not be possible to open.

  Next, the attachment side member 510 is attached to the substrate case 200 in which the game control board 101 is sealed. The attachment-side member 510 is elastically deformed on both side pieces 510 d and 510 d outward and attached to the stepped portion 203 b of the upper case 203. Then, by releasing the elastic deformation, the engaging pieces 511 and 511 are attached by engaging with the engaging grooves 212 and 212 on the back surface of the lower case 201. At this time, the base piece 510a and the upper pieces 510c and 510c of the attachment-side member 510 are in contact with the top surface of the step 203b and the bottom surface of the recess 203f of the upper case 203, respectively, and the notch 512 provided in the base piece 510a The board-side connector 620a of the game control board 101 housed in the board case 200 is connected to the inside of the board case 200 through the notch 512 and the insertion hole 234 so as to coincide with the insertion hole 234 provided in the recess 203f of the upper case 203. To be exposed to the outside.

  Next, the mounting screw 259 is screwed into the housing side wall through the screw hole 252 of the mounting base 250 to fix the mounting base 250 to the housing, and the locking portions 257 and 257 of the fixing member 255 are fixed. The fixing member 255 is attached to the mounting base 250 by fitting into the engaging grooves 254a and 254a of the mounting base 250, respectively.

  Next, the board case 200 to which the attachment side member 510 is attached is assembled to the attachment base 250. Specifically, after inserting the locking pieces 235 and 235 protruding to one end side of the substrate case 200 into the locking holes 251a and 251a of the locking holes 251 and 251 of the mounting base 250, respectively, as shown in FIG. The substrate case 200 is accommodated between the side walls 250b and 250c of the mounting base 250, and the upper surface of the other end side step portion 203a of the substrate case 200 is locked by the locking claw 253a of the locking column 253, thereby fixing the substrate case 200. Temporarily fix to the mounting base 250. In this state, the four sealing pieces 232 provided at one end of the upper case 203 and the fixing holes 256 of the fixing member 255 attached to the mounting base 250 are in corresponding positions, and in this state, any of the sealing pieces The sealing piece 232 and the fixing member 255 are fixed by screwing the aforementioned one-way screw into the corresponding fixing hole 256 from above the H.232.

  Then, by fixing the sealing piece 232 and the sealing piece fixing member 255, the movement of the substrate case 200 in the removal direction from the mounting base 250 at the end of the substrate case 200 on the sealing piece 232 side is restricted and the locking is performed. Since the horizontal movement of the substrate case 200 toward the sealing piece 232 side is also restricted by the pillar 253, the locking pieces 235 and 235 protruding to one end side of the substrate case 200 are removed from the locking holes 251 a and 251 a of the mounting base 250. It becomes impossible. Further, in this state, the screw holes 252 of the bottom plate 250a of the mounting base 250 are all covered with the substrate case 200, and access to the mounting screws 259 is impossible, and the mounting base 250 cannot be removed from the housing. Become. In this way, the substrate case 200 to which the attachment-side member 510 is attached is fixed to the housing via the attachment base 250, and the substrate case 200 is attached to the housing unless the sealing piece 232 or the fixing member 255 is broken. It will be in the state which cannot be removed from.

  When the board case 200 to which the attachment side member 510 is attached is fixed to the attachment base 250 (housing) so as not to be detached, as shown in FIG. 13A, the side piece 510d of the attachment side member 510 is provided. 510d abuts against the inner surfaces of the side walls 250b, 250c of the mounting base 250 and is held between them so that deformation of the both side pieces 510d, 510d of the mounting side member 510 outward is restricted. It becomes impossible to remove from 200.

  Next, as shown in FIG. 9, the cable 600a is connected to the board-side connector 620a of the game control board 101 exposed through the insertion hole 234 of the board case 200 and the notch 512 of the base piece 510a in the attachment-side member 510. After connecting the cable-side connector 610a, with the board-side connector 620a and the cable-side connector 610a connected, as shown in FIG. 12, the covering portion 521 of the connector cover 520 covers the upper side of the cable-side connector 610a. Then, the locking cylinder 522 of the connector cover 520 is fitted into the locking hole 513 a of the locking hole 513 in the attachment side member 510. As a result, the engaging portions 523 and 523 of the locking cylinder 522 abut against the inner periphery of the locking hole 513a and elastically deform inward. At this time, when the engaging portions 523 and 523 are positioned to cover the cable-side connector 610a with the covering portion 521, the shallow groove portions 514a and 514a among the engaging grooves 514 and 514 formed on the inner surface of the locking hole 513a. The locking cylinder 522 is further fitted, and the locking claws 523a and 523a at the tips of the engaging portions 523 and 523 reach the shallow groove portions 514a and 514a of the engaging grooves 514 and 514, As shown in FIG. 11A, the inward elastic deformation of the engaging portions 523 and 523 is released, and the locking claws 523a and 523a engage with the shallow groove portions 514a and 514a, respectively. The upward movement is restricted, and the side surface 521a of the covering portion 521 is brought into contact with the side surfaces of the board-side connector 620a and the cable-side connector 610a, so that the locking cylinder 522 is locked. By rotating against the part 513 is restricted, and ligated with the mounting member 510 and the connector cover 520, a state of integrated connector regulating member 500 is formed. In this state, since the engaging portions 523 and 523 are covered with the locking hole portion 513, it is impossible to elastically deform the engaging portions 523 and 523 inward from the outside, and the connector cover 520 or the attachment side member Unless 510 is broken, the connector cover 520 cannot be removed from the attachment side member 510.

  When the connector cover 520 is detachably attached to the attachment side member 510, a part of the upper surface of the cable side connector 610a is covered with the covering portion 521 as shown in FIGS. The movement of 610a in the pulling direction from the board side connector 620a is restricted, and the removal of the cable side connector 610a from the board side connector 620a is restricted.

  As described above, with the mounting side member 510 attached to the board case 200, the board case 200 is fixed to the housing, and then the cable side connector 610a is connected to the board side connector 620a. By attaching a part of 620a to the attachment side member 510 so as to cover from above, the cable side connector 610a cannot be removed from the board side connector 620a.

  Next, a situation when the connection between the cable side connector 610a and the board side connector 620a is released will be described.

  In order to release the connection between the cable side connector 610a and the board side connector 620a, the attachment side member 510 or the cable cover 520 is broken and the connector cover 520 is removed from the attachment side member 510, or the sealing piece 232 of the board case 200 is removed. Alternatively, it is necessary to break the fixing member 255, remove the board case 200 from the mounting base 250, and remove the mounting side member 510 with the connector cover 520 attached thereto from the board case 200.

  For example, when it is necessary to remove the cable-side connector 610a from the board-side connector 620a due to a failure of the cable 600a or the like, the latter method is used when the board case 200 is to be removed and replaced by the former method. Just remove it.

  First, when replacing the cable 600a, when it is necessary to remove the cable-side connector 610a from the board-side connector 620a, a method for removing the connector cover 520 from the attachment-side member 510 will be described. First, a connector such as a nipper is used. The connecting piece 522a that connects the covering portion 521 of the cover 520 and the locking cylinder 522 is broken. As a result, the covering portion 521 is separated and the locking cylinder 522 can be rotated with respect to the locking hole portion 513. In this state, by rotating the locking cylinder 522 counterclockwise as viewed from above, the engaging portions 523 and 523 move from the shallow groove portions 514a and 514a of the engaging grooves 514 and 514 to the positions of the deep groove portions 514b and 514b. Then, as shown in FIG. 11A, from the state where the locking claws 523a and 523a are engaged with the shallow groove portions 514a and 514a, as shown in FIG. 11B, the locking claws 523a and 523a The shallow groove portions 514a and 514a are disengaged. As a result, the locking cylinder 522 can be moved upward. As shown in FIG. 11C, when the locking cylinder 522 is pulled upward, the locking claws 523a and 523a are engaged with the deep grooves 514b and 514b. However, in this state, since the engaging portions 523 and 523 are exposed, the engaging portions 523 and 523 can be elastically deformed inward, and the engaging claws 523a can be elastically deformed inwardly. 523a and the deep groove portions 514b and 514b are disengaged, and the locking cylinder 522 can be detached from the attachment side member 510, whereby the connector cover 520 is completely separated from the attachment side member 510, and the connector cover 520 Since the restriction of the movement in the pulling direction of the cable side connector 610a due to is also released, the connection between the cable side connector 610a and the board side connector 620a is released. Door will be able to.

  When the connector cover 520 is removed from the attachment-side member 510, the covering portion 521 and the locking cylinder 522 are broken, and once broken, the original state is not restored. Therefore, the connection between the cable-side connector 610a and the board-side connector 620a There will be traces of unlocking.

  Next, when it is necessary to remove the cable side connector 610a from the board side connector 620a when replacing the whole board case 200, a method of removing the attachment side member 510 from the board case 200 together with the connector cover 520 will be described. The sealing piece 232 of the substrate case 200 fixed to the fixing member 255 is broken with a tool such as a nipper. As a result, the end of the substrate case 200 on the side of the sealing piece 232 can be moved away from the mounting base 250, so that the locking claw 253 a of the locking column 253 and the stepped portion 203 e of the substrate case 200 Release the engagement. Accordingly, the horizontal movement toward the sealing piece 232 is also possible, so that the locking pieces 235 and 235 of the board case 200 are removed from the locking holes 251a and 251a of the mounting base 250. Thereby, the board case 200 is detached from the attachment base 250, and the side pieces 510d and 510d of the attachment side member 510 can be deformed outwardly, without removing the connector cover 520 from the attachment side member 510. The attachment-side member 510 can be removed from the board case 200. With this, the attachment-side member 510 is removed from the board case 200 in a state of being integrated with the connector cover 520, whereby the cable-side connector 610a is removed by the connector cover 520. Since the restriction on the movement in the direction is also released, the connection between the cable side connector 610a and the board side connector 620a can be released.

  In order to remove the attachment side member 510 from the substrate case 200 also by this method, the sealing piece 232 of the substrate case 200 fixed to the fixing member 255 needs to be broken. Therefore, a trace of releasing the connection between the cable side connector 610a and the board side connector 620a remains.

  Further, according to this method, the sealing piece 232 of the board case 200 is broken and remains on the fixing member 255, but the attachment side member 510 can be removed from the board case 200 without removing the connector cover 520 from the attachment side member 510. Therefore, by attaching the attachment side member 510 in a state where the connector cover 520 is assembled to the new board case 200 in which the game control board 101 is accommodated for replacement, the cable side connector 610a and the board side in the new board case 200 are attached. The connection with the connector 620a is disabled, the new fixing member 255 is mounted on the mounting base 250, and the new board case 200 with the mounting side member 510 with the connector cover 520 assembled is mounted on the mounting base. 250 and the fixing member 255 and the sealing piece 232 are fixed to each other. Doing, becomes again impossible removably mounting member 510, when releasing the connection between the cable-side connector 610a and the substrate-side connector 620a is in a state leave its mark. That is, in such a case, the attachment side member 510 and the connector cover 520 can be reused.

  Next, the detailed structure of the connector restricting member 650 will be described.

Has been. In particular, the notch 682c for releasing the cable 612g connected to the board-side connector 622g is formed to be narrower than the length of the long side of the cable 601g, and both ends of the notch 682c are covered from the cover portion 689. Pieces 683 and 683 are respectively provided.

  Further, on both side surfaces on the long side and one side surface on the short side of the cover member 680, the locking holes are projected so as to protrude outward at positions corresponding to the locking holes 661 of the mounting table 660. A locking cylinder 684 having substantially the same diameter as the inner peripheral surface of 661b is provided via a connection piece 684a. Lock holes 684 are formed on the outer peripheral surface of the lock cylinder 684 at locations corresponding to the pair of lock claws 661c provided on the inner periphery of the lock hole 661b. Can be combined.

  Next, the mounting state of the mounting table 660 and the cover member 680 will be described. First, as shown in FIG. 14, the operation unit relay board 107 is mounted on the mounting table 660, and the board-side connectors 621a, 622a, 622b, 622c. , 622d to 622f and 622g are connected to cable side connectors 611a, 612a, 612b, 612c, 612d to 612f and 612g, respectively. After connecting these cable side connectors to the board side connector, the cover member 680 is attached to the mounting table 660.

  Specifically, the locking cylinder 634 of the cover member 680 is fitted into the locking hole 661 b of the corresponding locking hole 661 of the mounting table 660. Then, by pushing the locking cylinder 634 into the locking hole 661b, the locking claw 661c in the locking hole 661b is engaged with the locking hole 684 of the locking cylinder 684. As a result, it becomes impossible to release the engagement between the locking claw 661c and the locking hole 684 from the outside, and as shown in FIG. 15, the mounting table 660 and the cover member 680 are connected to the locking hole. If the part 661 or the locking cylinder 634 is not broken, it is in a state where it is assembled so that it cannot be removed.

  When the mounting table 660 and the cover member 680 are assembled, as shown in FIG. 16A, the upper surfaces of both ends of the cable side connector 611a connected to the board side connector 621a of the operation unit relay board 107 are cover members.

  When the mounting table 660 and the cover member 680 are assembled, as shown in FIG. 16B, the upper surfaces of both ends of the cable side connector 612g connected to the board side connector 622g of the operation unit relay board 107 are covered with the cover member. 680 is covered with the covering pieces 683 and 683 so that the movement of the cable-side connector 621g from the board-side connector 622g is restricted, and the removal of the cable-side connector 621g from the board-side connector 622g is restricted. ing.

  Next, the situation when the connection between the cable side connector 611a and the board side connector 621a and the connection between the cable side connector 621g and the board side connector 622g are released will be described.

  To release the connection between the cable-side connector 611a and the board-side connector 621a and the connection between the cable-side connector 621g and the board-side connector 622g, a connection piece 684a that connects the locking cylinder 684 of the cover member 680 with a tool such as a nipper is provided. Break. As a result, the main body of the cover member 680 and the locking cylinder 684 are separated, and the cover member 680 can be removed from the mounting table 660. By removing the cover member 680 from the mounting table 660, the covering portions 681c and 681c. The restriction on the movement of the cable-side connector 611a in the removal direction is released, and the restriction on the movement of the cable-side connector 621g in the removal direction by the covering pieces 683 and 683 is also released, so the cable-side connector 611a and the board-side connector 621a are released. And the connection between the cable-side connector 621g and the board-side connector 622g can be released.

  When the cover member 680 is removed from the mounting table 660, the main body of the cover member 680 and the locking cylinder 684 are broken. Once the cover member 680 is broken, the original state is not obtained and the separated locking cylinder 684 is removed from the mounting table 660. Therefore, there remains a trace that the connection between the cable-side connector 611a and the board-side connector 621a and the connection between the cable-side connector 621g and the board-side connector 622g are released. It will be.

  In the slot machine 1, a winning is awarded when the winning symbols are arranged on any winning line of the variable display device 2. The type of winning combination is determined according to the gaming state. In addition to the normal gaming state, the gaming state includes a regular bonus and a big bonus as a special gaming state, and RT in which the winning probability of replay is higher than that in the normal gaming state. There are three types of RTs: RT1, RT2, and RT3, of which RT2 and RT3 are specific gaming states that are advantageous to the player, and RT1 is aimed at RT2 or RT3 after the end of the big bonus. It is a gaming state provided so as to be easy, and is included in the normal gaming state in a broad sense.

  In addition, the types of winning combinations are roughly divided into special roles with transition to a special gaming state (regular bonus, big bonus), small roles with belly medals (bell, cherry), and number of bets. There is a re-playing combination (replay A, replay B, replay C) that allows the next game to be started without the need for setting. FIG. 17A is a view for explaining the combination of the types of winning combinations in the slot machine 1 and the symbols in the variable display device 2.

  The regular bonus is awarded when the combination of “BAR-BAR-BAR” is aligned on any winning line in the normal gaming state, RT1, RT2 or RT3. When the regular bonus is won, the gaming state shifts from the normal gaming state, RT1, RT2 or RT3 to the regular bonus. The regular bonus ends when 12 games are consumed or when 8 games are won (any kind of combination is possible), whichever comes first. While the game state is in the regular bonus, the regular bonus medium flag is set in the RAM 112 (including the case where it is provided during the big bonus described below).

  The big bonus (1) is won when a combination of “red 7-red 7-red 7” is aligned on any winning line in the normal gaming state, RT1, RT2 or RT3. The big bonus (2) is won when a combination of “white 7-white 7-white 7” is arranged in any winning line in the normal gaming state, RT1, RT2 or RT3. When the big bonus (1) or the big bonus (2) is won, the gaming state shifts to the big bonus.

  In the big bonus, the regular bonus described above is repeatedly provided until the end. While the gaming state is the big bonus, the big bonus medium flag is set in the RAM 112. The big bonus ends when the number of medals paid out to the player exceeds 465. Here, since the maximum payout number per game is 10, the upper limit of the payout medal number in the big bonus is 475. After the big bonus is over, the gaming state is controlled to RT1 for the subsequent 15 games (however, regular bonus, big bonus (1) or big bonus (2), or replay B or replay C won) Until you do).

  Even if the regular bonus, the big bonus (1) or the big bonus (2) is won in the internal lottery to be described later, “red 7”, “white 7”, and “BAR” are 5 for all of the reels 3L, 3C, 3R. Since they are not arranged at intervals within a frame, depending on the operation procedure of the stop buttons 12L, 12C, and 12R, there are cases where these winning combinations are not won.

  The bell is awarded when a combination of “bell-bell-bell” is arranged on any winning line in any gaming state, and ten medals are paid out. Since all the reels 3L, 3C, and 3R have “bells” arranged at intervals of 5 frames or less, they also win regular bonus, big bonus (1) or big bonus (2). Except when priority is given to the derivation of, if the player wins the bell, the player wins the bell regardless of the operation procedure of the stop buttons 12L, 12C, 12R.

  Cherry is awarded when the symbol “Cherry” is derived on any winning line for the left reel 3L in any gaming state, and two medals are paid out per winning line. When “cherry” is stopped at the upper or lower stage of the left reel 3L, the derivation is made on two pay lines, so that a total of four medals are paid out.

  Replay A is awarded when the combination of “JAC-JAC-JAC” is aligned on any winning line in the normal gaming state, RT1, RT2 or RT3. Replay B is awarded when a combination of “watermelon-JAC-JAC” is aligned on any winning line in the normal gaming state, RT1, RT2 or RT3. Replay C is awarded when the combination of “JAC-JAC-Bell” is aligned on any winning line in the normal gaming state, RT1, RT2 or RT3.

  When one of Replay A to Replay C wins, no medals are paid out, but the next game can be started without setting the number of bets again. This is essentially the same as paying out three medals. In addition, when the replay B is won in the normal gaming state or RT1, the gaming state is controlled to RT2 only during the subsequent 100 games, and when the replay C is won, the gaming state is maintained only during the subsequent 150 games. It is controlled by RT3 (however, until a regular bonus, a big bonus (1) or a big bonus (2) is won). Even if the player wins Replay B or Replay C at RT2 or RT3, the gaming state does not change.

  As will be described later, a small bonus (bell, cherry) or replay A may be won in a state where the regular bonus, big bonus (1) or big bonus (2) is being carried over. The replay B and the replay C may be won simultaneously with the regular bonus, the big bonus (1) or the big bonus (2). Replay A to Replay C are derived in preference to the regular bonus, big bonus (1) or big bonus (2), and the regular bonus, big bonus (1) or big bonus (2) takes precedence over the small role. Will be derived.

  Hereinafter, the internal lottery will be described. The internal lottery is to determine whether or not the winning of each of the above combinations is permitted before the display result of the variable display device 2 is derived and displayed (actually, when the start lever 11 is operated). . In the internal lottery, a random number for internal lottery (an integer from 0 to 65535) is acquired from the random number generation circuit 115. Then, for each combination determined according to the gaming state, the acquired random number for internal lottery, the number of bets set by the player, and each combination determined according to the set value set by the setting switch 91 This is performed according to the number of judgment values. Winning in the internal lottery is exclusive.

  In the internal lottery, the number of judgment values registered for each game state and set value for each combination is sequentially added to the random number for internal lottery. It is judged that it was won. If the winning combination is determined, the winning flag of the combination is set in the RAM 112. The number of determination values is registered in the ROM 113 in the winning combination table by gaming state.

  FIG. 17B is a diagram showing a winning combination table by gaming state. The winning combination table by game state is stored in advance in the ROM 113, and is a table in which the number of determination values for each lottery target for each gaming state in the internal lottery is registered. Here, only a predetermined set value is shown, but a slightly different value is registered according to a difference in the set value. In the internal lottery, a plurality of combinations may be subject to lottery at the same time. In accordance with this winning state-specific winning table, in the internal lottery, regular bonus, regular bonus + replay B + replay C, big bonus (1), big bonus (1) + replay B + replay C, big bonus (2), big bonus ( 2) + Replay B + Replay C, Bell, Cherry, Replay A, Replay B + Replay C The number of determination values is acquired in order according to the gaming state.

  However, for regular bonuses (including those offered during the big bonus), the regular bonus, regular bonus + replay B + replay C, big bonus (1), big bonus (1) + replay B + replay Since 0 is registered as the number of determination values of C, big bonus (2), big bonus (2) + replay B + replay C, replay A, replay B + replay C, these roles are not won.

  In addition, for the normal gaming state and the gaming state of RT2 or RT3, 0 is registered as the judgment value number of replay B + replay C, but regular bonus + replay B + replay C, big bonus (1) + replay As the number of determination values of B + replay C, big bonus (2) + replay B + replay C, 90 is registered respectively. In other words, when replay B + replay C is won in a gaming state other than RT1, a regular bonus, a big bonus (1), or a big bonus (2) will be won at the same time.

  In the normal gaming state, RT1, RT2 or RT3, when the regular bonus, big bonus (1) or big bonus (2) winning flag has not been carried over from the previous game, regular bonus + replay as a draw target If it is determined that B + replay C, big bonus (1) + replay B + replay C, big bonus (2) + replay B + replay C are read, replay B and replay C, regular Bonus, big bonus (1) or big bonus (2) will be won simultaneously. In other words, in a game won by Replay B and Replay C, there is a possibility of winning a regular bonus, a big bonus (1), or a big bonus (2).

  Also, even in the normal gaming state, RT1, RT2 or RT3, when a regular bonus, a big bonus (1) or a big bonus (2) is won in the previous game, and the winning flag is carried over, There will be no regular bonus, big bonus (1) or big bonus (2). In such a case, if the regular bonus + replay B + replay C, big bonus (1) + replay B + replay C, big bonus (2) + replay B + replay C are read as the lottery target roles, If it is determined, only Replay B and Replay C are won.

  In addition, in the normal gaming state, the number of judgment values of Replay A in RT1, RT2, RT3, the number of judgment values of Replay B + Replay C (regular bonus, big bonus (1) or big bonus (2) in the case of simultaneous winning (Including the number of judgment values) is the same for each set value. However, the total number of replay determination values is 8992 in the normal gaming state, 17184 in RT1, 50604 in RT2, and 37658 in RT3.

  By setting the total winning probability of replay in this way, in the normal gaming state, the medal payout rate is considerably smaller than 1 (that is, internal to the number of medals inserted for setting the bet number). The smaller the number of medals that will be paid out for the small role won in the lottery). Even at RT1, the total winning probability of replay is higher than in the normal gaming state, but the medal payout rate is still smaller than 1. However, in RT1, since Replay B + Replay C with the transition to RT2 or RT3 is won with a probability of 1/8, it is more likely to replay than to play 15 games in RT1 and return to the normal gaming state. In many cases, B or Replay C is won to be controlled by RT2 or RT3.

  In RT2 and RT3, the total winning probability of replay is further increased, so that the medal payout rate is greater than 1. Particularly in RT2, the replay A is won with a very high probability of approximately 1 / 1.4. Therefore, the medal payout rate is considerably larger than 1. However, the medal payout rate in RT2 is also smaller than the medal payout rate in the regular bonus provided by the big bonus (1) or the big bonus (2). The relationship of the medal payout rates according to the gaming state described here is the same when the set value is any of 1-6.

  Next, stop control of the reels 3L, 3C, 3R will be described. The reels 3L, 3C, and 3R constituting the variable display device 2 rotate on condition that the start lever 11 is operated and a predetermined time has passed since the start of rotation of the reels 3L, 3C, and 3R in the previous game. Be started. When the stop buttons 12L, 12C, and 12R are operated by the player, the corresponding reels 3L, 3C, and 3R are within the maximum stop delay time range of 190 milliseconds (4 frames pull-in range). In)).

  The reels 3L, 3C and 3R stop rotating so that the winning symbol set in the winning line is aligned on the winning line within the range of the maximum stop delay time of 190 milliseconds, and the maximum stop of 190 milliseconds It is controlled so that the symbol of the combination for which the winning flag is not set within the delay time is not aligned on the winning line.

  Here, when the replay B winning flag and the replay C winning flag are set in duplicate due to simultaneous winning, the replay B symbols can be aligned on the winning line by operating the stop buttons 12L, 12C, 12R. When the replay B is won and the symbols of the replay B cannot be aligned on the winning line, the replay C is won.

  More specifically, when the left stop button 12L is operated first, the operation timing is the timing at which the “watermelon” of No. 19 can be stopped at any of the upper, middle and lower stages, that is, No. 12 to If it is the timing when the 19th symbol is located in the lower stage, the “watermelon” is stopped at any of the upper, middle and lower stages. For the second and third stops and the right reels 3C and 3R, “JAC” is arranged within 5 frames, so the left reel 3L is on the winning line where “JAC” is stopped. “JAC” is stopped and Replay B is awarded.

  On the other hand, if the left stop button 12L is operated for the first time and the operation timing is the timing when the symbols other than 12th to 19th are located in the lower stage, it is placed in any of the upper, middle and lower stages. Stop “JAC”. For the second and third reels 3C and 3R stopped, “JAC” was stopped for the inner reel 3C, “Bell” was stopped for the right reel 3R, and “Watermelon” was stopped for the left reel 3L. Stop on the winning line and win Replay C.

  When the left stop button 12L is operated third, “JAC” is stopped in the middle of the middle reel 3C, “bell” is stopped in the lower part of the right reel 3R, and “JAC” is stopped in the upper part. It is in a tempered state that doubles into C (since these can be stopped at any position). If the timing at which the left stop button 12L is operated is the timing at which the symbols 14th to 19th are located in the upper stage, the 19th “watermelon” is stopped in the upper stage and awarded to the replay B. If it is the timing, “JAC” is stopped at the lower stage and the replay C is won.

  When the left stop button 12L is operated for the second time, if the reel 3C is stopped before the reel 3L, the operation timing of the left stop button 12L is 12th to 19th. If it is the timing that is positioned in the lower stage, it wins Replay B, and if it is any other timing, it wins Replay C. If it is the right reel 3R that stops before the reel 3L, the operation timing of the left stop button 12L is the timing when the symbols 14th to 19th are positioned in the upper stage, and the replay B If it is a timing other than that, it will win Replay C.

  When the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag and replay A winning flag, replay B winning flag or replay C winning flag are set redundantly, replay A, replay B Alternatively, control is performed so that the symbols of Replay C are preferentially arranged on the winning line. Regardless of the operation procedure of the stop buttons 12L, 12C, 12R, the player will win Replay A, Replay B or Replay C. In this case, winning the regular bonus, big bonus (1) or big bonus (2) Absent. The replay B winning flag and the replay C winning flag are set so as not to overlap with the regular bonus winning flag, the big bonus (1) winning flag or the big bonus (2) winning flag. Is the same as

  When the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag and bell winning flag are set in duplicate, the regular bonus, big bonus (1) or big bonus (2) It is controlled so that the symbols are prioritized and aligned on the winning line. If the symbols of regular bonus, big bonus (1) or big bonus (2) cannot be aligned on any winning line due to the operating procedure of the stop buttons 12L, 12C, 12R, “Bell” is the winning line. If they are aligned on the top, the “bells” can be aligned on the winning line and the bells can be awarded.

  If the regular bonus winning flag, big bonus (1) winning flag or big bonus (2) winning flag and cherry winning flag are set in duplicate, the regular bonus, big bonus (1) winning flag or big bonus ( 2) Control is performed so that the winning flag pattern is preferentially aligned on the winning line. When the symbols of the regular bonus, big bonus (1) winning flag or big bonus (2) winning flag cannot be aligned on any winning line according to the operating procedure of the stop buttons 12L, 12C, 12R, If the “cherry” can be derived to the upper or lower stage of the reel 3L, the “cherry” is derived to the upper or lower stage to win the cherry.

  Note that the stop control of the reels 3L, 3C, and 3R described above is based on the stop operation position of the reels that have not yet stopped according to the gaming state and the setting state of the winning flag (and the symbols derived for the reels that have already stopped). A stop control table that defines the relationship between the stop position and the stop position is created in advance for unreacted reels, and when the stop buttons 12L, 12C, and 12R are operated, the stop control table created in advance is referred to and The rotation of the reel to be stopped is to be stopped. In the stop control table, the stop position is uniquely determined with respect to the stop operation position.

  On the game control board 101 side, the internal lottery is performed as described above, and the rotation of the reels 3L, 3C, 3R is stopped according to the result and the operation timing of the stop buttons 12L, 12C, 12R, and a prize is generated. It will be a thing. As a result of winning a prize, a medal is paid out or a game state is transferred as a payout. In this way, depending on the progress of the game on the game control board 101 side, an original effect is performed on the effect control board 102 side. Is called. In order to perform such an effect, the CPU 121 of the effect control board 102 must be able to recognize the progress of the game on the game control board 101 side. Is transmitted from the game control board 101 to the effect control board 102.

  The CPU 121 of the effect control board 102 sequentially takes out the commands received from the game control board 101 one by one, and based on the commands, the reel lamp 3LP, the liquid crystal display 4, the speakers 7L, 7R, 7U, and the game effect lamps 75A to 75M. It is assumed that the production process is controlled by controlling the production means. The command transmitted from the game control board 101 to the effect control board 102 includes a winning status notification command indicating the setting status of the winning flag in the RAM 112, a gaming status command indicating the gaming status applied in the next game, and the like. be able to.

  Hereinafter, a gaming operation in the slot machine 1 according to this embodiment will be described. Here, first, a special process executed when the slot machine 1 is activated will be described, and then a process when each game is repeatedly performed in the slot machine 1 will be described. In the following description, the term “game” means, in a narrow sense, from the operation of the start lever 11 until the reels 3L, 3C, 3R are stopped. However, when a game is played, the number of bets before the operation of the start lever 11 is set, and medals are paid out and the game state is shifted after the reels 3L, 3C, 3R are stopped. Is also included in the “game” in a broad sense. In the following description, descriptions of processes not related to the present invention may be omitted.

  When the slot machine 1 is started with the setting key switch 92 turned ON, the mode shifts to the setting change mode. Here, the stepping motor steps constituting the reel motors 3ML, 3MC, and 3MR in the storage area of the RAM 112, respectively. Initialize all storage areas except the counter that counts and the stack area in use. In the setting change mode, when a new setting value is set by the setting switch 91 and the setting key switch 92 is turned off after the new setting value is confirmed by the operation of the start lever 11, the game control process described below is performed. It will be a transition.

  On the other hand, when the slot machine 1 is activated with the setting key switch 92 in the OFF state, it is diagnosed whether the data in the RAM 112 is corrupted. If the data in the RAM 112 is corrupted, a RAM abnormality error occurs. Shift to RAM error processing. The RAM abnormality error processing cannot be canceled by operating the first reset switch 48 or the second reset switch 93. As described above, the setting key switch 92 is turned on to start the slot machine 1 again and set the setting value again. It cannot be canceled without resetting.

  On the other hand, when an error related to rotation of the reels 3L, 3C, 3R, an error related to winning determination, an error related to payout such as a hopper error, etc. occurs, the first reset switch 48 or the second reset switch It is possible to recover from these errors by the operation 93.

  When the data in the RAM 112 is not broken, that is, when the data when the power of the previous slot machine 1 is turned off remains normal, the data stored in the RAM 112 is left as it is and will be described next. The game control process is shifted to. In other words, when the slot machine 1 is activated with the setting key switch 92 turned off, if the data in the RAM 112 is not corrupted, the game is resumed from the previous state when the slot machine 1 was disconnected.

  FIG. 18 is a flowchart showing a game control process performed by the CPU 111 of the game control board 101 for each game. This process is also executed after the power is turned on and a predetermined boot process is performed, or immediately after the setting is changed by operating the setting switch 91. When the process of one game is started, first, an initial process including a process of clearing a predetermined area of the RAM 112 is performed (step S101).

  Next, the number of bets is set by operating one BET button 14 or MAXBET button 15 or by inserting medals from the medal insertion slot 13, and operating the start lever 11 to substantially change the game. BET processing for instructing start is performed. (Step S102). In the BET process, not only the bet number is set, but also by operating the settlement button 16, the already set bet number and credits can be settled and the corresponding number of medals can be paid out. When the bet number has already been set and credits remain, the bet number is settled by the first operation of the settlement button 16 and the credit is settled by the second operation.

  Further, in the slot machine 1 according to this embodiment, the number of bets for starting the game is limited to 3, and the start lever 11 does not become effective until 3 is set as the number of bets. If the player has won a replay in the previous game, the same number of bets as the previous game is automatically set by the flag during the replay game (the flag during the replay game is erased at this stage).

  When the bet number is set by the BET process and the start lever 11 is operated, a random number for internal lottery is extracted, and based on the extracted random number value, each combination determined according to the gaming state and the bet number A lottery process for determining whether or not winning is permitted is performed (step S103). In the lottery process, the number of determination values of the lottery target registered in the winning combination table according to gaming state in FIG. 17B is sequentially read according to the gaming state, and sequentially added to the extracted random number. And it determines with having won the lottery object combination when the result of addition overflows.

  However, if the winning flag of Big Bonus (1), Big Bonus (2) or Regular Bonus has been carried over from the previous game, the lottery target will be Big Bonus (1), Big Bonus (2) or Regular Bonus Even if it overflows at some point, it won't win again. When the lottery target is Big Bonus (1) + Replay B + Replay C, Big Bonus (2) + Replay B + Replay C, Regular Bonus + Replay B + Replay C, and only the Replay B and Replay C wins Determined.

  When it is determined that the player has won the bell, cherry, or replay A with the big bonus (1), big bonus (2), or regular bonus winning flag carried over from the previous game, the bell, cherry, or replay A The winning flag is set to overlap. If there is a lottery target combination determined to have been won in the lottery process, the winning flag is set in the RAM 112. Here, for example, when the big bonus (1) + replay B + replay C is won, the big bonus (1) winning flag, the replay B winning flag, and the replay C winning flag are set in an overlapping manner.

  Also, when the RT1, RT2 or RT3 gaming state, that is, when the value of the RT1 counter, RT2 counter, or RT3 counter is not 0, a regular bonus, a big bonus (1) or a big bonus (2) may be won. As a result, the values of the RT1, RT2 and RT3 counters are not initialized to zero. That is, simply winning the regular bonus, the big bonus (1), or the big bonus (2) does not end the gaming state of RT1, RT2, RT3.

  When the lottery process is completed, a reel rotation process is performed (step S104). In the reel rotation process, the reel motor is operated on the condition that a predetermined time (for example, 4.1 seconds) has elapsed from the start of rotation of the reels 3L, 3C, and 3R in the previous game. 3ML, 3MC, and 3MR are driven to start rotation of all the left, middle, and right reels 3L, 3C, and 3R. When predetermined conditions (detection of the reference position by the reel sensors 3SL, 3SC, 3SR after the rotation speed reaches a certain speed) from the start of rotation of the reels 3L, 3C, 3R are satisfied, the stop buttons 12L, 12C, 12R Is enabled. After that, when the stop buttons 12L, 12C, and 12R are operated by the player, the reel motors 3ML, 3MC, and 3MR are stopped according to the stop control table selected according to the setting state of the winning flag, and the reels 3L, 3C, and Stop the rotation of 3R.

  When the driving of each of the reels 3L, 3C, and 3R is stopped, a winning determination process is performed to determine whether any of the above-mentioned role symbols is derived and displayed on any winning line in the display mode at the time of stopping. (Step S105). If it is determined in this winning determination process that a winning combination has been won, a process corresponding to the winning combination is performed. Details of the winning determination process will be described later.

  When the winning determination process ends, a payout process is performed (step S106). In the payout process, when the winning flag for the small combination is set in the winning determination process, the credit is increased by the number corresponding to the small combination. However, when the number of credits accumulated as data reaches 50, the hopper motor 82 is driven to pay out an excess number of medals from the medal payout slot 71.

  Also, in the payout process, the number of digest games and winning games in the regular bonus, the total number of payout medals in the big bonus, the number of RT1, RT2, and RT3 digest games are counted. A process of terminating the regular bonus, the big bonus, or the gaming state of RT1, RT2, RT3 is also performed. When the big bonus is ended, 15 is set as the initial value of the RT1 counter (the value of the RT1 counter is not subtracted in the game, and one game is ended).

  In the payout process, the RT1 counter, RT2 counter (initial value 101 is set when replay B winning is determined), RT3 counter (initial value 151 is set when replay C winning is determined). When the value of is not 0, a process of subtracting 1 from the values of these counters is performed. As a result of the subtraction, when the values of the RT1 counter, the RT2 counter, and the RT3 counter become 0, RT1, RT2, and RT3 are ended, respectively, and the normal gaming state is controlled.

  The values of the RT1 counter, the RT2 counter, and the RT3 counter are 0 when a regular bonus, a big bonus (1), or a big bonus (2) is won, as will be described in detail in the winning determination process described later. The RT1 counter, RT2 counter, and RT3 counter values are not initialized to 0 simply by winning the big bonus (1) or the big bonus (2), and the gaming states of RT1, RT2, and RT3 do not end.

  Further, in the payout process, the process of deleting the winning flags of various small roles and Replay A to Replay C is also performed. However, the winning flags of Big Bonus (1), Big Bonus (2), and Regular Bonus are If they do not win a role, they are carried over to the next game without being erased. When a winning combination is determined in the winning determination process and a winning flag is set, the winning flag is also deleted here. Then, the process for one game ends, and the process for the next one game starts.

  Next, the winning determination process in step S105 will be described in detail. FIG. 19 is a flowchart showing in detail the winning determination process executed by the CPU 111 in step S105. In the winning determination process, the winning combination corresponding to the gaming state is read in order from the beginning (step S201). Next, it is determined whether or not the symbol combination of the read combination is aligned with any of the five winning lines of the variable display device 2 (step S202).

  If the combination of symbols for the combination is complete, a winning flag for the combination is set in the RAM 112 (step S203), and the process proceeds to step S204. If the symbol combination of the combination is not complete, the process proceeds to step S204 as it is. In step S204, it is determined whether there is a combination that has not yet been determined as a winning determination among the combinations corresponding to the gaming state. If there is a winning combination that has not yet been determined for winning, the process returns to step S201, and the next winning combination corresponding to the gaming state is read out.

  If all of the winning combinations corresponding to the gaming state are targeted for winning determination, then it is determined whether or not any of Replay A to Replay C has been won depending on whether or not the replay winning flag is set in the RAM 112. (Step S205). If any of Replay A to Replay C has been won, a replay game in-progress flag is set in the RAM 112 (step S206). The replay game in-progress flag is deleted when the bet number is automatically set in the next game.

  Next, referring to the values of the RT2 counter and the RT3 counter, it is determined whether or not the current gaming state is RT2 or RT3 (step S207). If either of the RT2 counter and the RT3 counter is not 0 and the current gaming state is RT2 or RT3, the winning determination process is terminated as it is, and the process returns to the flowchart of FIG.

  If the current gaming state is neither RT2 nor RT3, it is determined whether or not the replay B has been won (step S208). If the player has won the replay B, the initial value of the RT2 counter is set to 101 and the value of the RT1 counter is initialized to 0. The reason why 101 instead of 100 is set as the initial value is that the RT2 counter value is decremented by 1 in the current game in the payout process in step S106 (step S209). Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  If the replay B has not been won, it is determined whether or not the replay C has been won (step S210). If the player has won the Replay C, 151 is set as the initial value of the RT3 counter and the value of the RT1 counter is initialized to 0. Here, 151 is set as the initial value instead of 150 because the value of the RT3 counter is decremented by 1 in the current game in the payout process in step S106 (step S211). Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  If none of Replay A to Replay C has been won, it is determined whether or not the big bonus (1) has been won depending on whether or not the big bonus (1) winning flag has been set in the RAM 112 (step S212). If the big bonus (1) has been won, the big bonus medium flag is set in the RAM 112 and the big bonus (1) winning flag set in the RAM 112 is erased. Further, the values of the RT1 counter, RT2 counter, and RT3 counter are all initialized to 0 (step S213). Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  If the big bonus (1) has not been won, it is determined whether or not the big bonus (2) has been won according to whether or not the big bonus (2) winning flag is set in the RAM 112 (step S214). If the big bonus (2) is won, the big bonus medium flag is set in the RAM 112 and the big bonus (2) winning flag set in the RAM 112 is deleted. Also, the values of the RT1 counter, RT2 counter, and RT3 counter are all initialized to 0 (step S215). Then, the winning determination process is terminated, and the process returns to the flowchart of FIG.

  If the big bonus (2) has not been won, whether or not the regular bonus has been won is determined based on whether or not the regular bonus winning flag is set in the RAM 112 (step S216). If the regular bonus is won, the regular bonus medium flag is set in the RAM 112 and the regular bonus winning flag set in the RAM 112 is erased. Also, the values of the RT1 counter, RT2 counter, and RT3 counter are all initialized to 0 (step S217). Then, the winning determination process is terminated, and the process returns to the flowchart of FIG. If the regular bonus has not been won, the winning determination process is terminated as it is, and the process returns to the flowchart of FIG.

  In the repetition of the game as described above, the CPU 111 of the game control board 101 shifts the game state between the normal game state, RT1, RT2, RT3, regular bonus, and big bonus, and the progress of the game In response, a command is transmitted to the effect control board 102. On the other hand, the CPU 121 of the effect control board 102 independently performs various effects processing based on the command received from the game control board 101. Since the effect processing executed by the CPU 121 of the effect control board 102 is not directly related to the present invention, detailed description thereof is omitted.

  As described above, in the slot machine 1 according to this embodiment, the gaming state is controlled to RT1 for 15 games after the end of the big bonus, but at RT1 with a relatively high probability of 1/8. , Replay B + Replay C will be won. When Replay B + Replay C is won, if the player operates the stop button 12L, 12C, 12R in the specific procedure described above, the player will win Replay B, and the stop button 12L in a procedure different from this specific procedure. , 12C, 12R will be awarded to Replay C. When the replay B is won, the game state is controlled by RT2, and when the replay C is won, the game state is controlled by RT3.

  As described above, when the replay B + replay C, which is established with a relatively high probability in RT1, is won, the player selects the operation procedure of the stop buttons 12L, 12C, and 12R, thereby allowing the player to select either RT2 or RT3. Intervene to control the state. Since the player can intervene in the kind of RT controlled in this way by his / her own operation, the interest of the game is improved.

  Even if the player intervenes in the selection of the RT type controlled by his / her own operation, the opportunity to control the gaming state at RT2 is the Replay B prize, and the opportunity to control the gaming state at RT3 is the replay. This is a C prize. Thus, since the display result of the variable display device 2 and the type of RT to be controlled are linked, it is determined from the display result derived to the variable display device 2 which of RT2 and RT3 is to be controlled. It will be easy to understand.

  Also, RT2 controlled by winning Replay B and RT3 controlled by winning Replay C are different in the number of continuous games from 100 games and 150 games, respectively. On the other hand, RT2 has a higher replay total win probability than RT3 and has a higher medal payout rate. For this reason, when replay B + replay C is won, by selecting the type of replay to win according to the operating procedure of the stop buttons 12L, 12C, 12R, is the game played at RT2, which has a high advantage even for a short period thereafter? Even if the advantage is somewhat low, the player can select whether to play the game at RT3 over a long period of time, and the game performance is further improved.

  Replay B + Replay C can only be won when the gaming state is controlled to RT1, but if it is a winning combination with regular bonus, big bonus (1) or big bonus (2). , A game state other than RT1, that is, a normal game state, RT2 and RT3 can be won (even RT1 can be won simultaneously). For this reason, when a player wins Replay B or Replay C, the player can expect to win the regular bonus, the big bonus (1), or the big bonus (2), so that the interest of the game can be further improved. .

  In particular, in the normal gaming state, RT2 or RT3, winning in Replay B or Replay C means that the regular bonus, big bonus (1) or big bonus (2) is always won at the same time. For this reason, the rare feeling of Replay B and Replay C other than RT1 will increase. Furthermore, since winning the replay B or the replay C without winning the regular bonus, the big bonus (1) or the big bonus (2) can only be in the gaming state of RT1, after the end of this big bonus Rareness can be given to the gaming state of RT1 controlled for only 15 games.

  In addition, the number of continuing games of RT1, RT2, and RT3 is determined to be 15 games, 100 games, and 150 games, respectively, but the regular bonus unless the regular bonus, big bonus (1), or big bonus (2) is won. RT1, RT2 and RT3 are not ended only by winning the internal bonus for the big bonus (1) or the big bonus (2). For this reason, the profits of RT1, RT2, and RT3 of 15 games, 100 games, and 150 games, respectively, will not be lost without the player's involvement.

  Further, the RAM 112 of the game control board 101 is initialized by changing the set value, but the value of the counter for counting the number of steps of the stepping motors that respectively constitute the reel motors 3ML, 3MC, and 3MR is not initialized. . For this reason, even after the set value is changed, the number of steps of the stepping motor (the number of steps counted by the counter of the RAM 112) constituting each of the reel motors 3ML, 3MC, and 3MR grasped by the CPU 111 is different from the actual number of steps. It is possible to prevent the player from perceiving that the set values have been changed because the excitation phases of the pulse signals are different and the reels 3L, 3C, 3R cannot start to rotate smoothly. .

  In addition, the full tank sensor 90 checks whether or not the overflow tank is full once per game. If full tank is detected, the full tank error is controlled. However, this check is not performed when the replay A, the replay B or the replay C is won in the previous game (that is, when the replay game flag is set in the RAM 112). If the player has won a replay in the previous game, the number of bets is set without the player inserting a medal, so the control unit 110 of the game control board 101 can be omitted by omitting a check for a full tank error that is unlikely to occur. The load applied to can be reduced.

  In addition, the external output board 105 receives a big bonus medium signal, a regular bonus medium signal, a reel control signal, a stop switch signal, a medal IN signal, a medal OUT signal, a winning status signal, and a security signal, such as a hall management computer. Output to the device. Here, the security signal includes a door open signal, a set value change signal, a closing error signal, a payout error signal, other error signals, and a settlement in-progress signal, but these are serially transmitted from the same output terminal in time division. Is output. Since the security signal is output in a time-division manner as described above, for example, a semiconductor chip mounted on the external output substrate 105 for outputting various signals can be reduced in size.

  In addition, since the security signal includes a signal during settlement, by monitoring this with an external device, it is possible to grasp that the settlement of medals according to the number of credits or bets is being performed. The store clerk of the amusement store can easily detect that such illegal acts are being performed. Furthermore, since the security signal includes an input error signal and a payout error signal, even if the store clerk of the game store is unaware of the error signal, by monitoring these with an external device, the game is not performed. An amusement shop clerk can easily detect that an act of illegally obtaining a medal (an illegal medal insertion action from the medal insertion slot 13 or an action of removing a medal from the hopper 80) is being performed. become able to.

  In addition, since the security signal includes a setting value change signal, it is possible to grasp that the setting value has been changed by monitoring this with an external device. The store clerk at the amusement store can detect that the cheating is being carried out. Furthermore, since the security signal includes a door opening signal, an act of illegally operating the setting switch 91 that can be operated by opening the front door is also performed by the amusement store. The store clerk can easily detect it.

  Further, a backup power source is mounted on the external output board 105, and even when the power of the slot machine 1 is turned off, the front door is opened by the door opening sensor 95 by power supply from the backup power source. It can detect that it is in a state and can output a security signal including a door opening signal to an external device. Even when the power of the slot machine 1 is turned off and no game is played, the semiconductor chips constituting the control unit 110 of the game control board 101 and the control unit 120 of the effect control board 102 are replaced with non-genuine products. Or the store clerk of the amusement store can easily detect that fraudulent acts such as attaching devices for taking out internal signals that are not output to the outside to these semiconductor chips are being carried out. Become.

  Further, the security signal includes another error signal indicating that an error other than the insertion error and the payout error has occurred. Errors other than insertion errors and payout errors do not occur in an attempt to increase medals directly, but there is a possibility that some kind of fraud has been performed when an error occurs. Further, if the notification is made with an error still occurring, the player cannot play the game. The store clerk of the game store can easily detect an illegal act and restart the game early by monitoring other error signals included in the security signal with an external device.

  Further, the external output board 105 outputs a medal IN signal collectively when the start lever 11 is operated. When the medal IN signal is output every time a medal set as the bet number is inserted, if the bet number already set is canceled by operating the settlement button 16, the output medal IN signal needs to be canceled. End up. The medal IN signal is output when the bet number is set from the credit by operating the single BET button 14 or the MAX BET button 15 and when the actual bet is set from the medal slot 13 To do this, a separate program is required. By outputting the medal IN signal collectively when the start lever 11 is operated as in the slot machine 1 according to this embodiment, such inconvenience can be prevented.

  On the other hand, the external output board 105 outputs a medal OUT signal every time one medal is paid out from the hopper 80. If the medals OUT signal is output as many as the number of medals to be paid out when the medals are paid out based on the small role winning, the hopper 80 may actually receive an out of medal error. An error occurs between the paid-out medals. In addition, if the medal OUT signals are output in batches for the number of medals paid out at the end of the medal payout, the medal OUT signal output may be continued after the next game is started. Sex occurs. By outputting a medal OUT signal every time one medal is paid out from the hopper 80 as in the slot machine 1 according to this embodiment, such inconvenience can be prevented.

  In addition, various commands are transmitted from the game control board 101 to the effect control board 102 according to the progress of the game, but more than the command transmission buffer provided in the RAM 112 of the game control board 101. The command reception buffer provided in the RAM 122 of the effect control board 102 has a larger capacity. For this reason, even if a large number of commands are sent from the game control board 101 at a time, it is possible to store enough unprocessed commands on the side of the effect control board 102, so that the CPU 121 of the effect control board 102 performs processing. It is possible to prevent a command that cannot be generated from occurring and hinder the execution of the performance.

  Further, in the slot machine 1 according to this embodiment, by attaching the connector restricting member 500 including the attachment side member 510 and the connector cover 520 to the board case 200, the game control board accommodated in the board case 200 is stored. The board-side connector 620a and the cable-side connector 610a are restricted from being removed, and in this state, the board case 200 is attached to the mounting base 250, and the fixing member 255 and the sealing piece 232 are fixed to each other. If the removal of the connector restricting member 500 is restricted and the sealing piece 232 of the board case 200 is broken to release the fixation between the board case 200 and the housing (mounting base 250), the board side connector The cable-side connector 610a cannot be removed from the 620a. In other words, the cable-side connector 610a cannot be removed without leaving a trace that the sealing piece 232 is broken, and a fraudulent instrument such as a driving instrument cannot be connected without leaving a trace. You will be able to discover that there is a possibility that

  Further, when the game control board 101 is replaced together with the board case 200 containing the game control board 101 due to a failure or the like, the sealing piece 232 is broken to fix the board case 200 and the housing (mounting base 250). If released, the connector restricting member 500 can be detached from the board case 200 and the cable side connector 610a can be removed from the board side connector 620a. Therefore, the connector restricting member 500 can be destroyed or the board case 200 can be destroyed. The cable-side connector 610a can be separated from the board-side connector 620a without opening.

  Further, the connector restricting member 500 is composed of an attachment side member 510 and a connector cover 520. After the attachment side member 510 is attached to the board case 200, the cable side connector 610a is connected to the board side connector 620a, and the board is in that state. The cable-side connector 610a cannot be removed from the board-side connector 620a by being attached to the attachment-side member 510 so as to cover a part of the cable-side connector 620a from above. Is connected to the board-side connector 620a, and then the locking cylinder 522 of the connector cover 520 is fitted into the locking hole 513a of the locking hole 513 of the attachment-side member 510 located around the board-side connector 620a. The connector cover 520 is simply attached to the attachment side member 510. Since part of the cable-side connector 610a is covered and the movement of the cable-side connector 610a in the unplugging direction is restricted, the assembly work is reduced when the removal of the cable-side connector 610a from the board-side connector 620a is restricted. it can.

  Further, even when the game control board 101 is housed in the board case 200, it is only necessary to connect the cable side connector 610a to the board side connector 620a as it is and then attach the connector cover 520. In this case, the assembly work can be more effectively reduced when the removal of the cable-side connector 610a from the board-side connector 620a is restricted.

  In addition, the connector cover 510 does not cover the entire connection portion between the cable-side connector 610a and the board-side connector 620a, but covers only a part of the cable-side connector 610a in the pulling direction side. Not only can the connector 610a be securely removed from the board-side connector 620a, but also the material required for manufacturing the connector cover 510 can be reduced.

  In addition, the connector cover 520 is attached to the attachment side member 510 with only one locking cylinder 522, but a rib that contacts the surface of the base piece 510a of the attachment side member 510 is provided on one side wall of the connector cover 520. Since 521b and 521b are formed and the movement of the connector cover 520 is restricted, the removal of the cable side connector 610a from the board side connector 620a can be reliably restricted.

  In addition, inwardly engaging portions 511 and 511 are formed at both ends extending from the base piece 510a of the attachment side member 510, and the engaging portions 511 and 511 are elastically deformed outward. In this state, the mounting member 510 is attached to the board case 200 by being assembled to the board case 200 and engaged with the locking grooves 514 and 514 formed on the back surface of the board case 200. Since the member 500 can be attached to the board case 200 without using other members such as screws and pins, the number of components can be reduced.

  Further, when the attachment side member 510 constituting the connector restricting member 500 is attached to the board case 200, the opposing surfaces of the attachment side member 510 to the base case 510 a and the upper pieces 510 c, 510 c with respect to the board case 200 are the steps in the upper case 203. The upper surface of the portion 203b and the bottom surface of the concave portion 203f are in contact with each other, and it is possible to effectively prevent attachment of unauthorized parts or the like between the connector restricting member 500 and the surface of the board case 200.

  Further, since the attachment side member 510 and the connector cover 520 constituting the connector restricting member 500 are both made of a transparent synthetic resin material, the visibility in the board case 200 may be impaired by the connector restricting member 500. Therefore, there is no problem in monitoring the game control board 101. Further, even when an unauthorized part is attached to the gap between the connector restricting member 500 and the board case 200, it can be easily found.

  Further, the connector connection between the game control board 101 and the inserted medal sensor 44, that is, the connection between the board side connector 620a of the game control board 101 and the cable side connector 610a of the cable 600a, the cable side connector 611a of the cable 600a and the operation unit. Regarding the connection between the board-side connector 621a of the relay board 107 and the connection between the board-side connector 622g of the operation part relay board 107 and the cable-side connector 612g of the cable 601g, the connection between these connectors is released. It is restricted by the member 650. As a result, any connector between the game control board 101 and the inserted medal sensor 44 is replaced with a connector such as an unauthorized driving tool and connected to the game control unit 110 of the game control board 101 and a signal related to the progress of the game. It is difficult to carry out fraudulent activities such as illegally inputting / outputting information, so that illegal sales can be effectively prevented.

  Further, in order to release the connector connection between the game control board 101 and the inserted medal sensor 44, the sealing piece 232 of the board case 200, the connection piece 522a of the connector cover 520, and the connection piece 684a of the cover member 680 are broken. As a result, when even one connector connection between the game control board 101 and the inserted medal sensor 44 is released, the trace remains and it is extremely difficult to erase the trace. , The above fraud can be more effectively suppressed.

  In addition, there is only one relay board between the game control board 101 and the inserted medal sensor 44, but in the case of passing through a plurality of relay boards, the removal of all connector connections existing between them is restricted. It is preferable to replace one of the connectors between the game control board 101 and the inserted medal sensor 44 with a connector such as an illegal driving tool and connect to the game control unit 110 of the game control board 101. Since it becomes difficult to perform an illegal act such as illegally inputting / outputting a signal related to the progress of the game, it is possible to effectively prevent the implementation of illegal business.

  Also, the first electronic components 45, 46, 41, 42L, 42C, 42R, 44, 3SL, 3SC, 3SR, 81 that input signals to the game control board 101 according to the progress of the game and the progress of the game Of the second electronic components 3ML, 3MC, 3MR, 82 for which signals are output from the game control board 101 in response, a connector restricting member is provided only for the connector connection between the inserted medal sensor 44 and the game control board 101. The release of the connection between each other is regulated. In other words, if there is no signal, the inserted medal sensor 44 cannot advance the game (if the signal from the inserted medal sensor 44 is not input, the number of bets cannot be set and the game cannot be started) and the game control. The connector restricting member is provided only for the connector connection with the board 101 to restrict the release of the connection between the connectors, and the connection between the other electronic components and the game control board 101 is released to drive the instrument. Even if it is replaced with a connector, it will be impossible to automatically advance the game automatically, so that it is possible to prevent fraud with the minimum restrictions, and to disconnect these connectors The number of parts can be reduced.

  In addition, a plurality of signal lines connecting the game control unit 110 and a plurality of electronic components that perform input / output of signals necessary for the progress of the game are provided between the game control board 101 and the operation unit relay board 107. By connecting the cable 600a to the board connector 610a of the game control board 101 and the cable connector 620a, that is, by restricting the release of only one connector connection, a plurality of signal lines are connected to each other. It is possible to restrict the release of the connection, and it is not necessary to prepare a plurality of parts for restricting the release of the connector connection, and the number of these parts can be reduced.

  Even when a plurality of signal lines connecting the game control unit 110 and a plurality of electronic components that perform input / output of signals necessary for the progress of the game are connected via a plurality of cables, the board side connectors are brought close to each other. It is necessary to prepare a plurality of parts for restricting the release of the connector connection by restricting the release of the connection between the plurality of board side connectors and the plurality of cable side connectors with one part. The number of these parts can be reduced.

  Also, the connection between the cable side connector 611a of the cable 600a connecting the game control board 101 and the operation part relay board 107 and the board side connector 621a of the operation part relay board 107 is released, and the operation part relay board 107 and the insertion medal sensor 44. Since the release of the connection between the cable-side connector 612g of the cable 601g and the board-side connector 622g of the operation unit relay board 107 is simultaneously restricted by one connector restricting member 650, the connection of the plurality of connectors is released. It is not necessary to prepare a plurality of parts for regulating the number of parts, and the number of these parts can be reduced.

  Further, after the backup power source of the game control unit 110 passes from the game control board 101 via the cable 600a-operation unit relay board 107-cable 601g-inserted medal sensor 44-cable 601g-operation unit relay board 107-cable 600a, Connection to the board side connector 620a of the game control board 101 and the cable side connector 610a of the cable 600a in the state where the power supply to the slot machine 1 is cut off and the cable 600a. The connection between the cable side connector 611a of the operation unit relay board 107 and the board side connector 621a of the operation unit relay board 107 and the connection of the board side connector 622g of the operation unit relay board 107 and the cable side connector 612g of the cable 601g is released. Backup power supply Supply line is disconnected, it can not hold data RAM112 the game control unit 110, so that the lost. That is, when even one connection between the game control board 101 and the inserted medal sensor 44 is released, the backup data held in the RAM 112 of the game control unit 110 is lost.

  On the other hand, in order to connect an unauthorized device such as a driving device, it is necessary to insert / remove the connector. However, even if a special device is selected or a gaming state is illegally used, it is replaced with a regular connector. Therefore, since the data in the RAM 112 is initialized by releasing the connection of the connector, the slot machine 1 set in a state in which the special role is won using the driving tool or in a game state advantageous to the player is used as a game. Unauthorized sales such as providing to a player at the start of business of a store can be prevented.

  The present invention is not limited to the above-described embodiment, and various modifications and applications are possible. Hereinafter, modifications of the above-described embodiment applicable to the present invention will be described.

  In the above embodiment, the engaging portions 511 and 511 of the attachment side member 510 are elastically deformed outward and engaged with the engaging grooves 514 and 514 formed on the back surface of the substrate case 200. When the attachment member 510 is attached to the substrate case 200 and the substrate case 200 to which the attachment side member 510 is attached is fixed to the attachment base 250 (housing) so as not to be detached, the side piece of the attachment side member 510 510d and 510d are in contact with the inner surfaces of the side walls 250b and 250c of the mounting base 250, and are held between them so that the deformation of the both side pieces 510d and 510d of the mounting side member 510 to the outside is restricted. The configuration is such that it cannot be removed from the case 200.

  On the other hand, for example, when a part of the attachment side member is fixed on the back surface of the substrate case 200 with a screw or a detachable locking pin, and the substrate case 200 is detachably attached to the housing (attachment base). In addition, the screws and the locking pins may be concealed, and the board case 200 may be attached to the housing so that the attachment side member is prevented from being removed from the board case 200. In addition to this, any structure can be used as long as the attachment-side member cannot be detached from the substrate case 200 after the attachment-side member is attached to the substrate case 200 and the substrate case 200 is fixed to the housing. A simple configuration may be adopted.

  In the above embodiment, the connector cover 520 is attached to the attachment side member 510 with only one locking cylinder 522. This configuration is preferable in that the structure of the connector cover 520 and the attachment side member 510 can be simplified. On the other hand, the connector cover 520 is provided with a plurality of locking cylinders 522, and the attachment side member 510 is provided with a locking hole 513a at each corresponding position, so that the connector cover 520 is attached to the attachment side member 510 at a plurality of locations. You may make it attach. By doing in this way, the removal | extraction with respect to the board | substrate side connector 620a of the cable side connector 610a can be controlled more firmly. Furthermore, in this case, it is preferable to attach the connector cover 520 to the attachment side member 510 at a plurality of locations across the connection portion between the cable side connector 610a and the board side connector 620a. The removal of the cable-side connector 610a from the board-side connector 620a can be more firmly regulated.

  In the above embodiment, only the connector connection between the inserted medal sensor 44 and the game control board 101 is provided with the connector restricting member to restrict the release of the connection between the connectors. On the other hand, only the connector connection between the start switch 41 and the game control board 101 may be provided with a connector restricting member to restrict the release of the connection between the connectors. In addition, if the reel is not configured to stop until the reel stop operation is performed after the reel starts rotating, only connector connection between the stop switch 42L, 42C, 42R and the game control board 101 is restricted. A member may be provided to restrict the release of the connection between the connectors. In these cases, the same effect as the above-described embodiment can be obtained.

  In the above embodiment, the backup power is returned from the game control board 101 to the game control board 101 via the inserted medal sensor 44 and supplied to the game control unit 110, so that the connector connection between them is established. When released, the data in the RAM 112 was lost. On the other hand, an electronic component that always inputs and outputs signals necessary for the progress of the game (for example, the start switch 41 or a configuration that does not stop the reel until the reel is stopped after the reel starts rotating. The same effects as those of the above-described embodiment can be obtained even through the stop switches 42L, 42C, 42R, etc.

  Capacitors and batteries that store backup power are mounted on electronic component mounting boards and relay boards (operation unit relay board 107, etc.) for these electronic components, which are required to input and output signals necessary for the progress of the game. A backup power supply line from a capacitor or a battery mounted on the mounting board or the relay board is connected to the game control board via a cable together with a signal line of the electronic component, and is supplied to the game control unit 110. You may make it do. Even in this case, when the connector connection between the mounting board or the relay board and the game control board 101 is released, the data in the RAM 112 will be lost. Since the control board 101 is supplied with backup power via a cable from a capacitor or battery mounted on the mounting board or relay board, the backup power is supplied to the game control unit 110 when the cable is disconnected. In order to continue supply, it is necessary to short-circuit the backup power supply line across the boards, and it is very difficult to release the connector connection while continuing to supply backup power. Connection can be effectively prevented.

  In addition, for example, it is equipped with a signal output circuit that always outputs a specific signal even in the event of a power failure, and always detects a specific signal even in the event of a power failure, and if the detection of a specific signal is interrupted, that fact Is mounted on the game control board 101, and the output path of this specific signal is controlled from the game control board 101 via electronic components that are required to input and output signals necessary for the progress of the game. Returning to the board 101, it is configured to be input to the signal monitoring circuit, and when the game control unit 110 is activated, it is confirmed whether or not the fact that the detection of the specific signal is interrupted is stored in the signal monitoring circuit, and the specific signal The data stored in the RAM 112 may be cleared when it is stored that the detection is interrupted. Even in such a case, it is possible to prevent illegal sales such as providing the game machine with the slot machine 1 set in a state where the special role is won using the driving tool at the start of the business of the game shop.

  In the above embodiment, when the slot machine 1 is started without turning on the setting key switch 92, the data is restored to the state before the power interruption using the data unless the data in the RAM 112 is destroyed. I was trying. Here, when the game control unit 110 is activated to return to the state before the power interruption, the CPU 111 transmits a power-on command indicating the winning status of the special role and the game state, and the CPU 121 of the effect control unit 120 When the insertion command is received, the winning situation and the gaming state of the special role may be notified on the liquid crystal display 4, the game number display 51, the credit display 52, and the payout display 53.

  To connect unauthorized devices such as driving tools, it is necessary to turn off the power once (disconnecting the connector without turning off the power will cause a failure). In this case, forcibly disconnect the connector. Even if you use a driving tool to illegally win a special role or set a game state that is advantageous to the player, when the game control unit 110 is restarted, the special role is won or an advantageous game Since it can be easily determined from the outside that it is controlled by the state, the slot machine 1 which is set to a state in which a special role is won using a driving tool or a game state advantageous to the player is operated by a game store. Unauthorized sales such as providing to a player at the start can be effectively suppressed.

  In the above embodiment, when the replay B + replay C is won in RT1, the game state is controlled by RT2 if the replay B is won, and RT3 if the replay C is won. On the other hand, in RT1, more types of replays (for example, three types of replay B, replay C, and replay D) are simultaneously won, and depending on the operation procedure of the stop buttons 12L, 12C, and 12R. You may be allowed to win. In this case, different RTs may be controlled for each type of Replay B, Replay C, and Replay D. However, RT2 is controlled when Replay B and Replay D are won, and RT3 is controlled when Replay C is won. It is also possible to control to RT2 when winning a replay B and controlling to RT3 when winning a replay C and replay D.

  In the above embodiment, in RT1, Replay B + Replay C is won with a probability of 1/8, but Replay A is also won with the same probability of about 1 / 7.3 as in the normal gaming state. It was a thing. In other words, the total winning probability of replay in RT1 is nearly twice as high as the total winning probability of replay in the normal gaming state, but a small value (replay B + replay) as the number of replay A judgment values in RT1. By registering the sum of the number of judgment values of C as 8992, or a value slightly larger (for example, 1), the total winning probability of replay in the normal gaming state and RT1 is ( Can be almost the same)

  In the above embodiment, the number of continuous games of RT2 is 100 games, the number of continuous games of RT3 is 150 games, and RT2 with a higher probability of winning Replay A has fewer continuous games than RT3. . However, how to determine the number of continuing games for RT2 and RT3 is not limited to this, and the number of continuing games for RT2 and RT3 may be the same. Alternatively, RT2 having a higher winning probability of Replay A may have a larger number of continuous games than RT3.

  If RT2 has a higher replay win probability and the number of continuous games than RT3, it seems that there is no point in letting RT3 control the gaming state, but how much RT2 is in the normal gaming state, Although the medal payout rate is higher than RT1 and RT3, the medal payout rate is lower than the regular bonus and the big bonus. In RT2, the regular bonus, the big bonus (1), or the big bonus (2) are selected with a very high probability to win the replay A derived in preference to the regular bonus, the big bonus (1), and the big bonus (2). ) Will be difficult to win.

  If you want to get a chance to be controlled by regular bonuses and big bonuses again before the store closes at the time just before the closing of the amusement store, it is more advantageous to select RT3 than RT2, so win replay than RT2. RT3 with a low probability and the number of continuous games is meaningful. Even if the RT2 and RT3 replay winning probabilities are the same, it is possible to easily return to the normal gaming state and win the regular bonus, the big bonus (1) or the big bonus (2). Can be obtained.

  In the above embodiment, the number of continued games in RT1 is 15 games, and the winning probability of Replay B + Replay C in RT1 is 1/8. However, the present invention is not limited to this. For example, if the winning probability of Replay B + Replay C in RT1 is lowered to about 1/50, conversely, the number of continued games in RT1 may be increased to 100 games. However, it is preferable to set the number of continuous games of RT1 and the winning probability of Replay B + Replay C so that, on average, the opportunity to win Replay B + Replay C at least once is obtained from the start to the end of RT1. .

  In the above embodiment, in RT1, which is controlled only for 15 games after the end of the big bonus, Replay B + Replay C is won with a relatively high probability, and the player's stop button 12L, 12C, 12R at this time In accordance with the operation procedure, either Replay B or Replay C is awarded, and a desired RT of RT2 and RT3 is controlled in gaming state. Of course, the opportunity to win a replay B + replay C with a relatively high probability that allows a desired RT of RT2 and RT3 to be controlled in this way is not limited to this. .

  For example, it may be given in a single bonus game state controlled by winning a single bonus combination in a normal game state. In this case, on average, there will be an opportunity to win Replay B + Replay C one or more times from the end of the big bonus or regular bonus until the next regular bonus, big bonus (1) or big bonus (2) is won. In addition, it is preferable to set the winning probability of the single bonus in the normal gaming state and the winning probability of Replay B + Replay C in the single bonus.

  In the above embodiment, when winning a replay B and a replay C based on the display result of the variable display device 2 in the normal gaming state or RT1, the gaming state is controlled to the specific gaming state RT2 and RT3, respectively. . Replay B + Replay C, which can be controlled to RT2 or RT3, will be won with a very low probability at the same time as regular bonus, big bonus (1) or big bonus (2) in the normal gaming state However, in RT1, which is controlled during 15 games after the end of the big bonus, Replay B + Replay C is won with a very high probability of 1/8.

  By the way, unless RT1 wins the regular bonus, the big bonus (1) or the big bonus (2), the RT1 does not end only by winning these roles, and RT2 or RT3 based on the winning of the replay B or the replay C. Until it is controlled or 15 games are consumed. On the other hand, RT1 is a specific type of small role or replay (specify) in addition to when a regular bonus, big bonus (1) or big bonus (2) is won, or when replay B or replay C is won. It can also be ended when winning a role.

  For example, in addition to each combination shown as a winning combination in the above embodiment, a single combination which is composed of a symbol combination of “BAR-JAC-JAC” and is a small combination in which one medal is paid out by winning. To do. For example, when the winning flag for one winning combination is set according to the result of the internal lottery, when the left stop button 12L is operated first, the symbols of No. 11 to No. 20 are in the lower row. At the timing of positioning, “BAR” is stopped at any of the upper, middle, and lower stages of the left reel 3L, and a winning combination is made (for the middle and right reels 3C and 3R, the stop button "JAC" can be stopped at any position regardless of the operation timing of 12C and 12R).

  Further, when the left stop button 12L is operated third, as in the case where the replay B winning flag and the replay C winning flag are set, “JAC” “Bell” is stopped at the lower stage of the reel 3R and “JAC” is stopped at the upper stage of the reel 3R. Then, if the timing at which the left stop button 12L is operated is the timing at which the symbols No. 14 to No. 20 are located in the upper stage, the “BAR” of No. 18 or No. 20 is stopped in the upper stage and a single winning combination is won. .

  When the left stop button 12L is operated second, if the reel 3C is stopped before the reel 3L, the operation timing of the left stop button 12L is 11th to 20th. If it is the timing that is positioned in the lower tier, a winning combination is won. If the right reel 3R is stopped before the reel 3L, the operation timing of the left stop button 12L is one when the symbols 14th to 20th are positioned at the upper stage. Win a role.

  The operation procedure of the stop buttons 12L, 12C, and 12R for winning a single winning combination that ends RT1 in this way is a transition to RT2 with a high replay winning probability when replay B + replay C is won. The operation procedure for making the replay B accompanied with a prize is included. In other words, if the stop buttons 12L, 12C, and 12R are operated so as not to win a single winning combination, only the replay C accompanied by the transition to RT3 having a low replay winning probability can be won. No game state can be transferred to RT2 with a high replay winning probability.

  In this case, the stop button 12L, 12C, 12R is a procedure in which the player can win the replay B in order to win the replay B, which has a higher replay win probability than the RT3 and has a higher medal payout rate. This procedure is included in the procedure for winning a single winning combination. Therefore, if a single winning combination is won instead of Replay B + Replay C, the winning combination is RT1. Will end. Once RT1 is over, Replay B + Replay C will not be won by this alone, except in very rare cases where a regular bonus, big bonus (1) or big bonus (2) will be won simultaneously. Both the RT2 and RT3 have almost no chance of controlling the gaming state.

  In this way, even if the risk of losing the chance of controlling the gaming state by RT2 and RT3 is lost, the payout rate of medals can be increased by operating the stop buttons 12L, 12C, and 12R in the procedure that enables winning to Replay B. Control RT2 with a medal payout rate lower than RT3 by avoiding operating stop buttons 12L, 12C, and 12R in a procedure that may challenge higher RT3 control or win a single winning combination Players will be given the option of taking safety measures. Thereby, gameability can be improved further.

  In addition, the operation procedure of the stop buttons 12L, 12C, and 12R for winning the replay B accompanied by the transition to RT2 is the operation of the stop buttons 12L, 12C, and 12R that wins a single combination that ends RT1. The procedure for operating the stop buttons 12L, 12C, and 12R that are completely included in the procedure and that does not win a single winning combination is the same as the procedure for operating the stop buttons 12L, 12C, and 12R for causing the replay C to win. It is completely included.

  That is, there is no operation procedure for the stop buttons 12L, 12C, and 12R that can be awarded to the replay B while avoiding the winning of the single winning combination that ends RT1, and in order to avoid the winning of the single winning combination. As long as the stop buttons 12L, 12C, and 12R are operated in the above procedure, the player will always win the replay C. For this reason, regardless of the skill of the player, the player is given the option of taking a risk measure or taking a safe measure, and the same game can be applied to both a high-skilled player and a low-skilled player. Sex will be provided.

  Furthermore, in addition to the above-described single-sheet combination (here, single-sheet combination A), a single-sheet combination B that ends RT1 is defined. When the symbol arrangement of FIG. 2 is adopted, “Cherry-JAC-JAC” (one-piece role B1), “Red 7-JAC-JAC” (one-piece role B2), “White 7-JAC” -JAC "(one-piece combination B3) is prepared, and one-piece combination B1, one-piece combination B2, and one-piece combination B3 are simultaneously elected at RT1. However, the probability of winning a one-piece combination B (simultaneously winning one-piece combination B1 to B3; hereinafter the same) is sufficiently lower than the winning probability of a single-piece combination A.

  Here, if the left stop button 12L is operated first when the single combination B is won, the operation timing is the timing at which symbols other than 15th to 17th are positioned in the lower stage. And a single winning combination B (one of the single winning combinations B1 to B3). Since the operation timing of the stop button 12L for winning the replay C is the timing when the symbols other than the 12th to 19th symbols are positioned in the lower stage, the timing for winning the single player B is close to this. ing.

  In this case, even if the stop buttons 12L, 12C, and 12R are operated in a procedure that allows winning to the replay B to be shifted to RT2, the stop buttons 12L, 12C, and 12R are pressed in accordance with the procedure that can be awarded to the replay C to be shifted to RT3. Even if it is operated, there is a risk that a single winning combination A or a single winning combination B will be won and RT1 will end. However, although the return obtained by winning the replay B and shifting to RT2 is large, the winning probability of the single player A is relatively high, so the risk that the RT1 will be terminated by winning the single player A is high. On the other hand, although the return obtained by winning the replay C and moving to RT3 is small, the winning probability of the single player B is relatively low, so the risk that the RT1 is terminated by the winning of the single player B is small.

  In this way, in the example of applying one type A and one type B that end RT1, the option to take a high risk / high return measure or a low risk / low return measure Will be given to the player. Thereby, gameability can be improved further.

  By the way, since the single winning combination (single winning combination A, B) that ends the gaming state of RT1 is missed by the operating procedure of the stop buttons 12L, 12C, 12R, If the player can dare to miss it, the game state of RT1 can be continued until 15 games are consumed. Therefore, when the game state is controlled by RT1, information that can specify that when one winning combination is won (if two types of one winning combination A and B are applied, the type can also be specified) The information is displayed on the liquid crystal display 4, and voices output from the speakers 7L, 7R, and 7U are notified to the player.

  The right (navigation right) to be notified of information that can be specified that this single winning combination has been won may be granted when the player clears a predetermined mission in the big bonus immediately before being controlled by RT1. it can. There may be a plurality of types of missions imposed on the player during the big bonus, and the player may be able to select a mission imposed by his / her own operation at the start of the big bonus.

  Thus, when the navigation right is granted in RT1, the player operates the stop buttons 12L, 12C, and 12R so as not to win a single combination according to the information notified when the single combination is won. Thus, RT1 can be prevented from being terminated. In this way, the player has more chances to control RT2 and RT3, which is advantageous to the player. The player intervenes in the game by his / her own operation regarding the continuation of RT1 (although RT1 itself is more advantageous to the player than the normal gaming state) Can improve the interest of the game. Furthermore, by allowing the player to select the type of mission imposed, the player's sense of intervention in the game can be further enhanced, thereby improving the interest of the game.

  A navigation right is granted every time a mission is cleared. For example, when a navigation right for five games is granted by completing one mission, the player clears one mission. If you win 5 games after the end of the big bonus, or if you complete 3 missions, then you will end up playing 15 games after the end of the big bonus. Can be notified. Or, if one navigation right is granted in one mission, if the player clears three missions, one role will be played until a specific role is won five times in RT1. It is possible to notify information capable of specifying that the player has been won.

  In addition to the advantageous RT (RT having the same replay winning probability as the RT in the above embodiment) such as RT2 and RT3 according to the above embodiment, the medal payout rate exceeds 1, Disadvantaged RT with a payout rate that is not significantly different from the normal gaming state (for example, an RT in which the number of judgment values of replay changes only 1 from the normal gaming state) is provided, which is advantageous depending on the winning state in the normal gaming state or RT2 It may be controlled to either RT (RT2 or RT3) or disadvantageous RT. The number of disadvantaged RT continuing games can also be set to a predetermined number.

  As a role for controlling the gaming state in such a disadvantageous RT, there is a missed role according to the operation procedure of the stop buttons 12L, 12C, 12R, and a role different from the role shown in FIG. Can do. The one-piece combination described above may be applied. Replay D (for example, “JAC-JAC-BAR”), which is a replaying player different from any of Replay A, Replay B, and Replay C, can also be applied.

  In this case, Replay B + Replay C for controlling RT2 or RT3, which is an advantageous RT, is won not only in RT1, but also in the normal gaming state (although the winning is not the case) Probability can be lower than RT1 in the normal gaming state), and while being controlled to the gaming state of RT1 for 15 games from the end of the big bonus, you can win the disadvantaged in the internal lottery It can not be.

  Further, even when a disadvantage is won when the player is controlled in the normal gaming state, information that can specify that fact can be notified to the player. With regard to the right to notify information that can identify what has been won for the disadvantage, if the gaming state immediately before being controlled to the normal gaming state is a big bonus, the player will have a predetermined bonus in the big bonus. It can be granted when the mission is cleared. The navigation right in this case, and the mission to grant it, may be the same as the navigation right to notify the winning of the specific role that ends the above advantageous RT and the mission to grant it. it can.

  In this way, when the navigation right is granted in the normal gaming state, the player operates the stop buttons 12L, 12C, 12R so as not to win the disadvantaged player according to the information notified when the disadvantaged player is won. By doing so, it is possible to prevent the disadvantageous RT from being controlled. As described above, the player can intervene in the game by his / her own operation even for the control to the disadvantaged RT, and the interest of the game can be improved.

  In the above embodiment, the difference between the number of continued games and the replay winning probability between RT2 which is a specific game state controlled by winning a replay B and RT3 which is a specific game state controlled by winning a replay C Were to be distinguished by. On the other hand, the specific gaming state controlled by the Replay B winning and the specific gaming state controlled by the Replay C winning may be distinguished from each other depending on the presence / absence of the small role winning. The specific game state controlled by the Replay B winning and the specific game state controlled by the Replay C winning may be distinguished from each other simply by the type of effect to be executed.

  In the above-described embodiment, the gaming state advantageous to the player is controlled by winning of Replay B and Replay C, in addition to RT1 controlled after the end of the big bonus, regular bonus, or big bonus. RT3 only. On the other hand, when the big bonus (1) or the big bonus (2) (or regular bonus) is won, the gaming state is changed to AT (Assist Time) until the prescribed number of games (for example, 30 games) is consumed. It is good also as what controls. During this time, control may be performed in conjunction with RT (which may be RT that has a large difference in replay winning probability compared to normal gaming state) in which the replay winning probability is higher than that in the normal gaming state.

  The winning combination for which the winning is notified by the AT controlled after the bonus winning may be composed of a plurality of types in which the operating procedures of the stop buttons 12L, 12C, 12R for winning are exclusive ( For example, “red 7”, “white 7” and “BAR” are arranged one by one at intervals of 7 frames for the middle and right reels 3C and 3R, and “bell-red 7-red 7” is assigned to the subject role A, "Bell-Red 7-White 7" is the subject role B, "Bell-Red 7-BAR" is the subject role C, "Bell-White 7-Red 7" is the subject role D, "Bell-White 7-White 7" Is the target role E, “Bell-White 7-BAR” is the target role F, “Bell-BAR-Red 7” is the target role G, “Bell-BAR-White 7” is the target role H, “Bell-BAR-BAR”. ”As a target role I).

  Here, when one of the types of target roles is won, the medal payout rate exceeds 1 if it is calculated that the winning items are always won. However, the proportion according to the type of the target role ( For example, if there are the above-mentioned target combinations A to I and the winning probabilities are the same, calculating that the winning combination can be won only in 1/9), the payout rate of medals is less than 1. Winning probability can be set.

  The game until winning the big bonus (1) or big bonus (2) (or regular bonus) and the prescribed game after winning the big bonus (1) or big bonus (2) (or regular bonus) The difference in the advantage for the player from the game until the number is exhausted is more than the difference in the winning probability of each combination in each game state, so that the game can be sharpened. Become. Moreover, since the AT after winning the big bonus (1) or big bonus (2) (or regular bonus) is a gaming state that is truly advantageous to the player on the premise of the technical intervention of the player, The fun of gaming can be further improved.

  In the above embodiment, the door opening sensor 95 detects that the front door is in an open state, and a door opening signal of the security signal is output from the external output board 105 based on the detection signal. It was a thing. However, the door opening sensor 95 may detect that the key for opening the front door is released. In this case, even if the front door is not actually opened, If the key is released, that is, if the door opening sensor 95 detects that the front door is openable, the door opening signal of the security signal is output from the external output board 105. Can do.

  Further, the detection signal of the door opening sensor 95 is input to the game control board 101, and when the door opening sensor 95 detects that the front door is in the open state, the CPU 111 of the game control board 101 A predetermined command indicating that may be transmitted to the effect control board 102. The CPU 121 of the presentation control board 102 that has received the predetermined command indicates that the front door is in an open state, for example, displays a predetermined message on the liquid crystal display 4 or reproduces a door opening sound to reproduce the speaker 7L, It is good also as what is output from 7R and 7U. The volume level for outputting the door opening sound is preferably the maximum level.

  Inside the slot machine 1, there are disposed boards equipped with control circuits for performing various controls, a setting switch 91 for changing set values, and the like. Must be opened. However, these operations are operations that a player cannot originally perform, and the fact that the front door of the slot machine 1 is opened by a person who is not a store clerk of the game store means that the player has been cheating. It is very likely that By notifying the opening of the front door by displaying a message on the liquid crystal display 4 or by outputting a door opening sound, the store clerk of the amusement store can easily detect that an illegal act is being performed. Become.

  In the above embodiment, the security signal among the signals output from the external output board 105 includes a door opening signal, a setting value change signal, a closing error signal, a payout error signal, another error signal, and a checkout signal. It was a serial signal output from the same output terminal in time division. However, it is not necessary for all these signals to be output in serial form from the same output terminal in a time division manner, and any two or more of these signals are output from the same output terminal in a time division manner. Can be. Further, such a plurality of types of signals may not be output in a serial format. In other words, when the front door is opened by the door opening sensor 95, the set value is changed, various errors including insertion errors and payout errors, or medal settlement occurs, the event is distinguished. It may be a signal that is turned on without being performed.

  In the above embodiment, the RAM 112 of the game control board 101 is initialized by changing the set value. However, the counter for counting the number of steps of the stepping motors constituting the reel motors 3ML, 3MC, and 3MR, respectively. Only the value was not initialized. This prevents the player from perceiving that the setting values are changed because the reels 3L, 3C, and 3R cannot start rotating smoothly after the setting values are changed.

  In contrast, when the slot machine 1 is activated regardless of whether or not the setting value has been changed, that is, whether or not the slot machine 1 has been activated with the setting key switch 92 turned ON, the stepping motor step is performed. The counter value for counting the numbers may be initialized so that each excitation phase of the stepping motor is always excited in the initial pattern. In this case, the reels 3L, 3C, and 3R behave the same immediately after activation regardless of whether or not the setting value is changed, so that the player is informed that the setting value has been changed. Can be prevented.

  In the above embodiment, the CPU 121 of the effect control board 102 performs the effect process in accordance with the command sent from the game control board 101. Of course, the commands sent from the game control board 101 are placed in a first-in first-out command reception buffer, and it is assumed that no processing is lost in the commands sequentially placed in the command reception buffer. In addition, a signal corresponding to the player's operation was not directly output to the CPU 121 of the effect control board 102.

  On the other hand, a touch panel capable of detecting the position touched by the player is provided as an effect operating means on the front surface of the liquid crystal display 4 controlled by the CPU 121 of the effect control board 102, and touched on this touch panel. A signal corresponding to the selected position may be output to the CPU 121 of the effect control board 102. And CPU121 shall perform an effect process according to the signal corresponding to the touch position detected by the touch panel in addition to the command received from the game control board 101. FIG.

  In addition, a command simulator (test game control board) can be connected to the effect control board 102 in place of the normal game control board 102 before shipment from the factory, and input from the command simulator. Based on various inspection commands, it is possible to inspect each effect means connected to the effect control board 102 and effect operation means such as a touch panel.

  Here, when receiving an inspection command for inspecting the operation of the touch panel, the CPU 121 displays, for example, a message “Please touch” on the liquid crystal display 4 on the rear surface while validating the entire surface of the touch panel. Whether or not a touch operation is detected can be checked. In this case, until a touch operation on the touch panel is detected, the CPU 121 can prohibit command reception interrupt processing and prohibit reception of new commands.

  In this way, when the inspection command for inspecting the operation of the touch panel is received and the operation of the touch panel is performed accordingly, the command reception interrupt process is prohibited until the touch operation is detected, and the reception of a new command is prohibited. Therefore, even if a new command is received between the reception of the inspection command and the detection of the touch operation, the processing based on the new command is not performed. For this reason, even when an inspection command is erroneously transmitted without waiting for completion of the operation check of the touch panel, the operation check of the touch panel can be normally performed. Note that the same operation can be performed when an effect operation means other than the touch panel, for example, a button or a dial is applied as the effect operation means.

  In the above embodiment, in any gaming state, the game can be started only by setting 3 as the bet number. However, the number of bets that can be set to start the game can be any number in the range of 1 to 3. The number of bets that can be set for each gaming state may be different. Here, when 1 or 2 was set as the bet number in the normal gaming state, the winning probability of the small role in the internal lottery was lowered and the prize was awarded to the small role than when 3 was set as the bet number. The number of payout medals can be increased.

  In the above embodiment, the stop control table is selected in advance based on the setting status of the winning flag, the stop position of the symbol is determined with reference to the stop control table when the reels 3L, 3C, 3R are stopped, and the stop The slot machine that stops the rotation of the reels 3L, 3C, and 3R by the table system that stops the reel at the position has been described as an example. In contrast, based on the current symbol position when the stop condition is satisfied and the setting status of the winning flag, pull-in control is performed so that the symbol of the winning symbol is aligned, or the symbol of the symbol that is not winning The present invention can also be applied to a slot machine that stops the rotation of the reels 3L, 3C, and 3R by a control method in which the removal control is performed so as not to be aligned.

  In the control method, when the operation of the stop buttons 12L, 12C, 12R is detected, the corresponding reels 3L, 3C, 3R are within the range of the maximum stop delay time of 190 milliseconds from the symbol displayed at that time ( It is determined whether or not there is a winning symbol having a winning flag set in a range of a total of five frames including the displayed symbol and the amount drawn.

  If there is a symbol with a winning flag set (determined from the symbol of the role that is given priority for derivation in duplicate wins), select the symbol for winning the winning combination and select the winning line (already stopped) When there is a reel, the winning display mode can be derived along with the symbols on the stopped reel. Otherwise, a symbol for not winning any combination is selected and derived. That is, even when the stop of the reels 3L, 3C, 3R is controlled by this control method, it can be derived by stopping the symbols within the range of the maximum stop delay time after the operation of the stop buttons 12L, 12C, 12R is detected. The display mode corresponding to the setting status of the winning flag is derived as the display result of the variable display device 2.

  In the above embodiment, the variable display device 2 includes the three reels 3L, 3C, and 3R in which a plurality of symbols are arranged in a predetermined order on the outer peripheral portion, and the symbols are driven by rotational driving of these reels 3L, 3C, and 3R. Was variably displayed. However, a device that virtually displays a symbol on a display device such as a liquid crystal display device may be used instead of the variable display device 2 described above.

  In the above-described embodiment, the slot machine to which medals are applied as a game medium used for setting the number of bets and giving game value associated with winning is described. However, the slot machine embodying the present invention may be a slot machine (so-called parrot) to which a game ball used in a pachinko gaming machine is applied as a game medium. When a game ball is used as a game medium, for example, one medal can correspond to five game balls.

  In a so-called parrot, game balls used as game media are stored in a storage tray in the same physical form, and when the player operates the BET button, the game balls stored in the storage tray (upper plate) are stored. The number of game balls corresponding to the BET operation is taken into the parrot via a predetermined take-in route. The number of bets for playing one game is set by the game balls taken inside.

  In addition, when the player operates the checkout button in the parrot, if the bet number has already been set (except when the bet number is automatically set after the replay win), it depends on the set bet number. A number of game balls are discharged to the lower pan provided at the bottom of the slot machine. If the bet number is not set (including the case where the bet number is settled first), the game balls stored in the storage tray are discharged to the lower tray through a predetermined route. The lower plate is provided with a hole through which a game ball stored by a player operating a predetermined lever is passed through the lower plate, and the game ball box (so-called dollar box) is placed under the lower plate. If operated, the game ball owned by the player can be easily transferred to the game ball box.
