Description

  The present invention relates to a gaming machine and a signal delay device that start rotation of a rotating cylinder by operating a rotation of a rotating cylinder, and in particular, a random number is generated based on the operation timing of the rotating rotation start of the internal lottery. The present invention relates to a gaming machine and a signal delay device.

The rotation of the rotating cylinder starts when the rotating cylinder rotation start means (for example, a start lever) is operated, and when the stopping means (for example, a stop button) is pressed, the rotation of the rotating cylinder stops and stops. There is known a gaming machine that determines a prize based on the arrangement of symbols drawn on the spinning cylinder.
This type of gaming machine includes, for example, a slot machine. The slot machine displays a plurality of symbols (hereinafter collectively referred to as “symbols”) such as predetermined pictures, characters, numbers, etc., when a player inserts a game medal as a game medium and presses a start lever ( (Usually 3) rotating cylinders start to rotate, and the rotating cylinder stops by pressing multiple (usually 3) stop buttons corresponding to each rotating cylinder at any timing. This is a gaming machine in which a predetermined number of medals are paid out according to the arrangement of the symbols of the trunk.

In general, in a slot machine, in order to increase the fun of the game, etc., a plurality of cylinders are automatically controlled with a certain probability, and the symbols attached to each cirrus are stopped so as to have a predetermined arrangement. The winning control called “inner hit” is performed.
In this internal winning control, when the game is started by pressing the start lever, the internal winning lottery (internal lottery) is automatically performed inside the slot machine for each game, and the winning contents (various wins and loses) And the stop position of the spinning cylinder is controlled according to the contents of the winning a prize. When a predetermined winning content is won, each time within a certain range regardless of the timing when the player presses the stop button. Stopping control is performed so that the symbols attached to the trunk are arranged in accordance with the contents of the winning prize, whereby a predetermined amount of medals is paid out.

  Specifically, when a predetermined winning content is won as a result of the internal lottery, a plurality of rotating cylinders are within a certain range (for example, within a range of 4 symbols from the position of the corresponding symbol), and the player Regardless of the timing at which each stop button is pressed, the symbols on the winning line are “7, 7, 7”, “BAR, BAR, BAR”, “Watermelon, Watermelon, Watermelon”, “Bell, Bell, Bell”, etc. Stop control (winning control) is performed so as to obtain a predetermined arrangement according to the winning content.

By executing the stop control of the spinning cylinder, the pressing timing of the stop button corresponding to each spinning cylinder deviates from the timing of stopping the symbols ("7" and "BAR") constituting the arrangement of a winning content on the arrangement. Even if the deviation is within a certain range (within 4 frames from the symbol, etc.), the symbol is stopped by mechanical control so that the symbol is positioned on a predetermined winning line, and the winning arrangement is configured. Is done.
As a result of this stop control, regardless of the skill of the game, if the player presses the stop button within a certain range, the spinning cylinder stops so that the symbol becomes a predetermined winning arrangement, so the player In this case, a predetermined amount of medals corresponding to the stopped winning arrangement is paid out.

Here, for the stop control of the spinning cylinder, there are “retraction control” for stopping the spinning cylinder so that a predetermined symbol arrangement is aligned, and “winning prevention control for stopping control so that a certain symbol arrangement is not aligned. There is. In the winning prevention control, for example, when a certain winning content is won, during the game, the spinning cylinder is stopped and controlled so that the symbol arrangement of the other winning content is not aligned.
In general, several kinds of winning contents are set as the winning contents for which such stop control of the spinning cylinder is performed, and any winning contents are determined for each game by internal lottery. .
The contents of the award are, for example, bonus games such as “Regular Bonus (RB)” and “Big Bonus (BB)” that allow a large amount of medals to be paid out, “Small” with a small amount of medals, and medal insertion There are several types, such as “replay” that can be played without a game, and “losing” that does not give out medals, and a predetermined number of winning medals are paid out according to the contents of each winning decision. In order to prevent this, the rotating drum is controlled to stop.

For example, in the case of a “small role”, the spinning cylinder is arranged so that several symbols (for example, 1 to 15) medals are paid out in one game unit (for example, an array in which “bell” symbols are aligned in a horizontal row). Is controlled to stop (pull-in control), and the rotating cylinder is controlled to stop so that other winning symbols (for example, “7, 7, 7” indicating “big hit”) are not aligned (winning prevention control). .
In the case of “RB”, after winning the lottery, a bonus game is started (winning) when a predetermined winning pattern (for example, “BAR, BAR, BAR”) is prepared, and a bonus game in which several games are set as one set thereafter. During the bonus game, the spinning cylinder is continuously controlled so that it becomes a “big hit” symbol arrangement with a “small role” and a large amount of payout, and more than 100 medals Will be paid out.

Similarly, in the case of “BB”, after winning the lottery, the big bonus game is started (winning) when a predetermined winning symbol (for example, “7.7.7”) is prepared, and the bonus game as described above. The spinning cylinder is controlled so that (RB) continues for several sets (usually three sets), and the game is set and controlled so that hundreds of medals are paid out.
When the result of the lottery is “losing”, each of the drums is stopped and controlled so that the symbols are arranged in an arrangement in which no medals are paid out (an arrangement in which none of the winning symbols are arranged) (winning prevention control).

  In a slot machine in which the spinning cylinder is controlled to stop in this way, if a specific winning content such as BB or RB is won as a result of the internal lottery, a certain amount of games will be made on condition that the game will be won in subsequent games. The media is surely paid out, making it very attractive to players. In other words, for a slot machine player, winning a specific winning content such as BB, RB, etc. by internal lottery is of greatest interest.

Here, in the internal lottery, the probability of winning content is controlled to a predetermined size. That is, the internal lottery in the slot machine is generally performed using a random number generator and a lottery table, and the random number generator repeatedly counts numbers within a predetermined range in order. The contents of the prize are assigned to the area.
Then, it is determined whether or not the winning content is won by determining whether or not the number counted at the timing when the player presses the start lever is the number assigned to the winning content by using the lottery table. (For example, refer to Patent Document 1).

For example, in a certain slot machine, one cycle for generating a random number is about 2.7 milliseconds, during which about 16,000 numbers are counted. Some of them use a lottery table in which various winning contents are associated with numbers from 0 to 5,000. In a slot machine using such a lottery table, it is possible to win some prizes with a probability of about one third, but since one cycle is a very small value of about 2.7 milliseconds, It is impossible for a human sense to press the start lever aiming at a timing at which a one-third prize winning content can be hit.
Therefore, the random number generated by the random number generator is truly random, and the winning probability of the internal lottery in the slot machine is normally obtained as set in the lottery table.
JP 2003-135664 A (2nd page)

However, in such a slot machine, the winning content is fixed at a specific position in the above counting cycle, so if the start lever is pressed at the same timing in the same cycle, the theoretically the same random number Will occur. This means that it is possible to always win the same winning content by once winning the winning content and pressing the start lever at a certain timing.
In addition, fraudulent acts with weak points in such an internal lottery of slot machines have occurred and become a problem.

  In other words, by depressing the start lever using a special device, an act of randomly drawing the winning contents in the count cycle as described above and assigning the winning contents illegally (hereinafter referred to as such illegal actions). The person who performs is referred to as a fraudster). Such illegal acts (so-called “goto”) include what are called solenoid goto, sensory device goto, and harness goto.

Specifically, for example, the solenoid got allows the start lever to be pressed at regular intervals using a solenoid. Then, by adjusting the timing of depressing the start lever, adjustment is made until winning is obtained, and once winning is achieved, the winning is almost automatically performed thereafter. Further, by repeating the adjustment, it is possible to aim for a winning combination such as RB or BB.
If such a fraudulent act is performed, the game hall would be returned to the player more than necessary. And if fraudulent acts occur frequently, it has caused a great deal of business damage and has become a problem.

  The present invention has been considered in view of the above circumstances, and a gaming machine capable of defending against an illegal act of unjustly acquiring a winning ball by pressing a start lever at regular intervals in accordance with a timing of winning a winning content. It is another object of the present invention to provide a signal delay device.

  In order to achieve this object, the gaming machine of the present invention generates a random number based on a rotation rotation start means for starting rotation of the rotation cylinder and a rotation rotation start signal from the rotation rotation start means. A gaming machine having a random number generating means, and having a signal delay means for delaying the time for the rotation start signal to reach the random number generating means and making the delay time indefinite.

  When the gaming machine has such a configuration, it is possible to delay the rotation rotation start signal sent from the rotation rotation start means and reach the random number generation means. For this reason, even if the fraudster operates the rotating rotation starting means in accordance with the period of winning in the internal lottery, the rotating rotation start signal reaches the random number generating means with a delay from the timing of this operation. As a result, the timing of arrival of the spinning cylinder rotation start signal deviates from the winning timing, so that the winning contents cannot be allocated. As a result, the act of illegally trying to obtain the prize ball unfairly can be made unsuccessful, and thus it is possible to defend against the act of illegally winning the internal lottery.

Moreover, according to the gaming machine of the present invention, it is possible to delay indefinitely the time for the spinning cylinder rotation start signal to reach the random number generation means. For this reason, even if the fraudulent person operates the rotating rotation starting means in consideration of the delay time, it can be avoided that the winning contents are continuously won.
For example, it is assumed that a fraudulent person obtains the timing for winning the winning content by operating the rotating rotation starting means in consideration of the delay time. Then, it is assumed that the spinning cylinder rotation start means is operated based on the timing in the next game. However, the delay time of the rotation rotation start signal differs between the previous time and this time, and therefore the winning timing also differs between the previous time and this time. As a result, the fraudster cannot win the winning content even if he / she operates the rotating rotation starting means based on the winning timing of the previous winning content. Therefore, it is possible to protect against an illegal act of unjustly acquiring a prize ball by operating the rotating rotation starting means at regular intervals in accordance with the timing of winning the winning contents.

Further, in the gaming machine of the present invention, the delay time of the spinning cylinder rotation start signal is indefinite. That is, the delay time of the rotation rotation start signal can be varied every time. For this reason, the delay time cannot be predicted.
This also makes it more difficult for fraudsters to win prizes.

The technique described in Patent Document 1 delays the timing at which the CPU acquires a random number from the latch means, and the timing at which the latch means acquires a random number from the counter circuit (one random number from a number of count values). It wasn't something that delayed the timing). In other words, in the technique described in Patent Document 1, the delayed start signal is sent to the CPU to control this CPU, and is sent to the random number generating means and the latch means to send these random number generating means. It did not control the latch means.
In addition, the technique described in Patent Document 1 is intended to ensure that the random numbers are different each time by delaying the timing at which the CPU obtains the random numbers from the latch means. It was not for defense purposes.
For this reason, even if it implements the technique of patent document 1, the objective of this invention cannot be achieved.

  In addition, the gaming machine of the present invention inputs a clock signal output circuit that outputs a clock signal at indefinite time intervals and a rotation rotation start signal, and also receives a clock signal from the clock signal output circuit. And a delay circuit that outputs a rotation rotation start signal based on the input timing.

If the gaming machine has such a configuration, a clock signal is output from the clock signal output circuit at an indefinite time interval, so that the delay circuit delays the rotation rotation start signal by an indefinite time by this clock signal. Can be output.
As a result, even if the fraudulent person operates the turning rotation start means at a fixed period so that the winning contents are won, the turning rotation start signal arrives at the random number generation means outside the winning timing, so that The winning details cannot be allocated. Therefore, it is possible to defend and defend against an act of illegally acquiring a prize ball by an unauthorized person.

  In the gaming machine of the present invention, the clock signal output circuit generates a plurality of signal generation circuit units that generate oscillation signals having different waveforms, and generates and outputs a clock signal having an indefinite period using the plurality of oscillation signals. The configuration includes a periodic clock generation circuit unit.

When the gaming machine has such a configuration, since the waveforms of the plurality of oscillation signals are different from each other, a clock signal generated based on these oscillation signals can be output at an indefinite period.
For example, if the waveform shape, period, frequency, and the like of each oscillation signal are different, the value indicated by each oscillation signal at a certain time and the action of each oscillation signal on other electronic elements are different. For this reason, the periodicity of the clock signal can be eliminated by combining a plurality of these different values and actions. As a result, the indefinite period clock generation circuit unit can output a clock signal in an indefinite period, and the delay circuit can randomly delay the rotation rotation start signal by the indefinite period clock signal.

In the gaming machine of the present invention, the plurality of signal generation circuit units include a triangular wave oscillation circuit unit that generates a triangular wave and a square wave generation circuit unit that generates a square wave.
If the gaming machine has such a configuration, since the shape of the signal output from each generation circuit unit is different, the indefinite period clock generation circuit unit can output the clock signal in an indefinite period.

In the gaming machine of the present invention, the triangular wave oscillation circuit unit generates a triangular wave having a period different from the period of the square wave generated by the square wave generation circuit unit.
When the gaming machine has such a configuration, the period of the triangular wave output from the triangular wave oscillation circuit unit and the square wave output from the square wave generation circuit unit can be made different, so that the indefinite period clock generation circuit unit Can output a clock signal at an indefinite period.

In the gaming machine of the present invention, the clock signal output circuit is configured by an analog circuit that oscillates using the amplification function of the electronic element.
When the gaming machine has such a structure, the electronic circuit has an amplification function, and thus the analog circuit can oscillate a predetermined clock signal using the amplification function.

Examples of the electronic element having an amplification function include an operational amplifier and a transistor. As an oscillation circuit using the amplification function of an electronic element, there are, for example, an LC oscillation circuit using an operational amplifier, a CR oscillation circuit, and Colpitts, Hartley, a CR phase oscillation circuit, etc. depending on the way of division.
The frequency stability of the clock signal oscillated from the clock signal output circuit composed of these analog circuits is lower than that of the signal oscillated from, for example, a crystal oscillator or a laser oscillator. This is because the characteristics of electronic elements (such as resistors and capacitors) used in the clock signal output circuit are affected by changes in temperature and the like.

In the present invention, the delay time of the start signal is not constant but indefinite. If this is made constant, the fraudulent person will perceive the delay time, and the timing of operation of the rotation rotation starting means that coincides with the winning timing of the winning contents will be detected, and it will not be possible to prevent it. Because.
Therefore, in the present invention, the delay time of the start signal is made indefinite using an analog circuit with low frequency stability. In other words, a crystal oscillator that oscillates a clock signal with high frequency stability is not used. As a result, even if the fraudster operates the rotating rotation start means so as to win the winning contents, the rotating rotation start signal arrives at the random number generating means with a delay from the winning timing. Can be avoided.

  In the gaming machine of the present invention, the delay circuit includes a flip-flop. The flip-flop has an input terminal for inputting a rotation rotation start signal, a clock terminal for inputting a clock signal, and an input timing of the clock signal. Basically, it has a configuration including an output terminal for delaying and outputting the rotation rotation start signal.

  When the gaming machine has such a configuration, the rotation rotation start signal can be output at the input timing of the clock signal. Therefore, when the rotation rotation start signal is input to the delay circuit, the clock signal is input and gradually output. As a result, the timing at which the spinning cylinder rotation start means is operated does not coincide with the timing at which the random number generation means acquires the random number. Therefore, it is possible to delay the time for the rotation rotation start signal to reach the random number generation means, and to prevent fraud.

In the gaming machine of the present invention, the signal delay means has a plurality of clock signal output circuits and / or delay circuits.
If the gaming machine has such a configuration, the periodicity of the delay time of the rotation rotation start signal can be further eliminated. Thereby, it is possible to make it more difficult to predict the delay time by the fraudster.

  The signal delay device of the present invention is a signal delay device for delaying a rotation rotation start signal transmitted from the rotation rotation start means to the random number generation means, and outputs a clock signal at indefinite time intervals. A configuration having an output circuit and a delay circuit that inputs a rotation rotation start signal, inputs a clock signal from the clock signal output circuit, and outputs a rotation rotation start signal based on the input timing of the clock signal is there.

  When the signal delay device has such a configuration, it is possible to delay the time for the rotation rotation start signal to reach the random number generation means. As a result, even if the fraudulent person operates the rotating rotation starting means at a certain period in order to win the winning content, the timing of the operation and the timing of the winning can be shifted. Therefore, it becomes possible to defend and defend against the fraudulent act that unfairly obtains the prize ball by the fraudulent person.

According to the present invention, it is possible to delay the time required for the rotation rotation start signal output from the rotation rotation start means to reach the random number generation means. For this reason, even if the fraudster operates the rotating rotation starting means in accordance with the winning timing of the winning content, the rotating rotation start signal arrives after the winning timing, so that the winning content is not won. Can be.
Therefore, it is possible to defend and defend against an illegal act of unjustly acquiring a prize ball by pressing the start lever at regular intervals in accordance with the timing at which the fraudster assigns the winning content.

Furthermore, since the delay time of the rotation rotation start signal is indefinite, it is difficult to predict the delay time, and therefore, illegal winning of the winning contents by the fraudulent person can be prevented.
In addition, by providing a plurality of clock signal output circuits and delay circuits, the periodicity of the rotation rotation start signal can be further eliminated.

Hereinafter, preferred embodiments of a gaming machine and a signal delay device according to the present invention will be described with reference to the drawings.
Note that the gaming machine of the present invention shown in the following embodiments is operated by a computer controlled by a program. The program sends a command to each component of the computer, and predetermined processing necessary for the operation of the gaming machine, for example, rotation and stop control processing of the spinning cylinder, lottery processing per inside, medal payout processing, and spinning rotation Start signal delay processing and the like are performed. Thus, each process and operation in the gaming machine of the present invention can be realized by specific means in which the program and the computer cooperate.

The program is stored in advance in a recording medium such as a ROM and a RAM, and is executed by causing the computer to read the program from a recording medium mounted on the computer. For example, the program may be read by the computer via a communication line.
Further, the recording medium for storing the program can be constituted by, for example, a semiconductor memory, a magnetic disk, an optical disk, or any other recording means readable by any computer.

Rotating the rotating drum (left) 21a, rotating drum (middle) 21b, rotating drum (right) 21c (see FIG. 2)), the symbols (characters, numbers, pictures, etc.) attached to the rotating drums 21a to 21c are predetermined. This is a swivel-type gaming machine that can win a winning medal by stopping the arrangement.

Specifically, the slot machine 1 is configured in a casing shape that houses necessary configurations and devices therein, and the front side is covered with a front door 10 so as to be freely opened and closed.
As shown in FIGS. 1 and 2, the front door 10 is a door body that is attached to the slot machine 1 so as to be openable and closable, and constitutes a front portion of the slot machine 1.

A display window 11 is provided at a substantially central portion of the front door 10.
The display window 11 is a window portion for visually recognizing the plurality of rotary cylinders 21a to 21c disposed inside the slot machine 1, and is usually made of a colorless, transparent or colored transparent resin panel or the like, and each of the rotary cylinders 21a to 21c. Among a plurality of symbols drawn around the symbol, a plurality of (usually three) symbols that are adjacent in the vertical direction can be visually recognized and identified.
A winning line 12 is drawn on the display window 11 (usually 5 lines), and the winning of the game is determined by a combination of symbols of the respective cylinders 21a to 21c stopped and arranged along the winning line 12. It has become so.

As shown in FIG. 1, a start lever 13 and a stop button 14 are provided below the display window 11 of the front door 10.
The start lever (rotating cylinder rotation starting means) 13 is a game starting means for starting the rotation of each of the rotating cylinders 21a to 21c. When the start lever 13 is pressed by a player's operation, the control means 30 described later is operated. A start signal (rotating cylinder rotation start signal) is output (see FIG. 3), and the rotating cylinders 21a to 21c inside the main body rotate all at once (or sequentially).
When a start signal is input by depressing the start lever 13, a random number is generated in a random number generation unit 33 of the control unit 30 described later (see FIG. 4), and the lottery of the control unit 30 is performed using the random number. In the means 34 (see FIG. 4), a lottery per inside is performed.

The stop button 14 is a stopping means for stopping the rotating cylinders 21a to 21c, and includes a plurality of stop buttons 14 (three rotating cylinders (for example, rotating cylinder (left ) 21a, rotator (middle) 21b, and rotator (right) 21c) are provided with three stop buttons (stop button (left) 14a, stop button (middle) 14b, stop button (right) 14c)). It has been.
When these stop buttons 14a, 14b, and 14c are pressed at an arbitrary timing of the player, a stop signal is output to the control means 30 (see FIG. 3), and the rotation of the corresponding cylinders 21a, 21b, and 21c is stopped. It has come to be.
Therefore, the player operates the start lever 13 and the stop button 14 to rotate and stop the plurality of spinning cylinders 21a to 21c, and the symbols attached to the spinning cylinders 21a to 21c are arranged in a predetermined winning arrangement. You can play slot machine games that align.

As in the case of a general slot machine, the rotating drum 21 is composed of a cylindrical member having a plurality of (usually 21) patterns and characters and the like drawn on the outer periphery, and is rotated in the vertical direction (vertical direction in the drawing). Two spinning cylinders (left) 21a, spinning cylinder (middle) 21b, and spinning cylinder (right) 21c are arranged in a line in the horizontal direction (left-right direction in the drawing) as shown in FIG.
The symbols provided in each of the spinning cylinders 21a to 21c are arranged at equal intervals for each of the spinning cylinders. For example, characters such as “7” and “BAR”, and a pattern or the like indicating a character or fruit of a slot machine are predetermined. They are displayed in order, and usually 21 symbols are displayed on each cylinder.
Then, when the corresponding stop buttons 14a to 14c are pressed down on the symbols of the spinning cylinders 21a to 21c, along the winning line 12 of the display window 11 described above, for example, "7-7.7" or " Winning is determined by stopping at a predetermined combination such as “BAR / BAR / BAR”.

The three drums 21 a to 21 c are controlled to be driven and stopped by a control unit 30 and a drum unit 20 provided in the slot machine 1. The drum unit 20 holds the three cylinders 21a to 21c in a freely rotatable manner, and the start lever 13 and the stop buttons 14a to 14c are pressed to operate, so that a pulse (drive) is generated from the control unit 31 of the control unit 30 described later. A signal is input (see FIG. 3), and control of start, constant speed rotation, and stop of the rotation of the corresponding rotating cylinders 21a to 21c is performed.
The drum unit 20 controls the stop position of the drum 21 in accordance with the result of the internal lottery performed by the control means 30, regardless of the timing at which the player presses the stop button 14, that is, the stop buttons 14 a to 14 c. Even if the pressing timing is deviated, the rotating cylinder 21 is controlled to stop so that the symbols of the corresponding rotating cylinders 21a to 21c are in a specific arrangement within a certain range (usually within the range of 4 symbols). Yes.

As shown in FIG. 1, a medal slot 15, a medal BET switch 16, and a MAXBET switch 17 are provided in the vicinity of the top of the start lever 13 and the stop button 14 of the front door 10.
The medal slot 15 is a slot for receiving medals as a game medium used in the game.
Here, a medal detection unit (see FIG. 3) is provided on the inside of the main body of the medal insertion slot 15, and the number of inserted medals is counted, and a medal signal indicating the number of medals is a control inside the main body. The information is output to the means 30.
Further, the number of medals inserted from the medal slot 15 is stored in the storage unit 32 in the control means 30 described later as the number of stored medals (see FIG. 3), and prior to the start of the game. A plurality of medals can be inserted in advance and stored and stored as stored medals.

The medal BET switch 16 is a medal insertion switch for inserting a medal to be used (multiplied) in the game from among the stored medals when the medal inserted from the medal insertion slot 15 has a stored medal.
When the medal BET switch 16 is pressed, a medal insertion signal is output to the control means 30 (see FIG. 3), and the same number of medals are inserted into the game from the stored medals in the storage unit 32. become.
The MAXBET switch 17 inserts the maximum number of medals (usually three medals) that can be inserted into one game from a stored medal by one press.

A medal payout port 18 is provided below the slot machine 1.
The medal payout opening 18 is configured such that when the symbols of the respective drums 21 stopped by pressing the stop button 14 are in a predetermined winning arrangement, a number of winning medals corresponding to the arrangement are paid out. .

[Control means]
Next, the control means 30 for controlling the slot machine according to the present embodiment configured as described above will be described with reference to FIGS.
3 is a block diagram showing an outline of the control means of the slot machine according to the present embodiment shown in FIG. 1, and FIG. 4 is a block diagram showing the configuration of the control unit 31.
As shown in FIG. 3, the control means 30 of the present embodiment is realized, for example, by executing a program by a microcomputer including a CPU, a RAM, a ROM, etc., and the processing of each part of the slot machine 1 as described above , Control the operation.
Specifically, the control means 30 of the present embodiment includes a control unit 31 and a storage unit 32 as shown in FIG.

  The control unit 31 inputs respective medal insertion signals from the medal insertion slot (medal detection unit) 15, the medal BET switch 16, and the MAXBET switch 17, the number of medals inserted from the medal insertion slot 15, The number of medals placed using the MAXBET switch 17 is confirmed, and the number of stored medals stored in the storage unit 32 is decreased based on the medal signals from the medal BET switch 16 and the MAXBET switch 17. As a result, the number of medals used (multiplied) for each game is determined.

  Further, the control unit 31 inputs a start signal from the start lever 13 and a stop signal from the stop buttons 14a to 14c, thereby outputting a pulse (drive) signal serving as a control signal for the drum 21 to the drum unit 20, The rotating drums 21a to 21c are rotated and stopped. As a result, in the drum unit 20, the rotating drums 21a to 21c are rotated by the start signal, and the corresponding rotating drums 21a to 21c are stopped by the stop signal input by the pressing operation of the stop buttons 14a to 14c.

  Further, the control unit 31 recognizes the stop symbol of each of the cylinders 21a to 21c from the marker signal input from the drum unit 20, and determines whether or not the stop symbol is a predetermined winning arrangement. As a result, when it is a predetermined winning arrangement, the number of medals is paid out according to the type of winning.

The storage unit 32 is a storage unit that stores and accumulates programs and various data (for example, the number of collected balls, the number of prize balls, the number of stored medals, etc.) necessary for controlling each part of the slot machine and the game control in the control unit 30.
For example, the storage unit 32 stores a lottery table (FIG. 5) used for internal lottery in the lottery means 34.

Meanwhile, as shown in FIG. 4, the control unit 31 includes a random number generation unit 33, a lottery unit 34, and a start signal delay unit 35.
The random number generation means 33 generates a random number for use in internal lottery. This random number generation means 33 has an IC counter generally called a random number generation device, and when the slot machine 1 is turned on, the number within a predetermined range is sequentially counted repeatedly. When the random number generation means 33 receives a start signal (start signal sent delayed from the timing when the start lever 13 is pressed) from the start signal delay means 35, the random number generation means 33 counts the number counted at the received timing. Output as a random number.

The lottery means 34 performs an internal lottery using the random number generated by the random number generating means 33. The lottery means 34 can be constituted by a CPU that performs a lottery process.
As in the case of the conventional slot machine, the lottery means 34 uses the lottery table preset and stored in the storage unit 32 to obtain lottery result information indicating the winning content corresponding to the random number. Is done.
As described above, the winning contents in each game are determined based on the result of the internal lottery, and the stop position of the rotary drum 21 is controlled in accordance with the winning contents. Regardless of the timing at which the button 14 is pressed, the stop control is performed so that the symbols attached to each cylinder 21 within a certain range are arranged according to the winning contents. That is, the control unit 31 outputs to the drum unit 20 a pulse (drive) signal for stopping and controlling the rotating drum 21 in a predetermined winning arrangement according to the lottery result of the lottery means 34, and the drum unit 20 rotates based on this signal. The stop position of the cylinder 21 is controlled. As a result, each of the drums 21a to 21c stops within a certain range so that the symbols are in a predetermined winning arrangement corresponding to the winning contents, regardless of the timing at which the stop buttons 14a to 14c are pressed.

  In addition, the contents of the prizes drawn and determined by the lottery means 34 are generally divided into several types such as “losing”, “replay”, “small role”, “regular bonus”, “big bonus”, etc. Also in this embodiment, the same winning contents are determined by lottery. However, the types and specific contents of the winnings are set according to the type and type of the slot machine, and there is no particular limitation for implementing the slot machine according to the present embodiment. .

  FIG. 5 is a diagram showing an example of the relationship between random numbers and winning contents for explaining generation of random numbers and internal lottery. The pie chart shown in the figure shows one cycle of the number counted by the random number generation means 33. The number counting by the random number generation means 33 can be repeated, for example, by incrementing the number by 1 and counting up to 16000 in about 2.7 milliseconds.

As shown in the figure, the contents of winning by internal lottery are set in advance in a predetermined area in one cycle of the counted number. In the example of FIG. 5, replay is indicated by 0 to 2200, other various small roles are assigned by 2201 to 4900, and RB and BB are assigned by 4901 to 5000.
The lottery means 34 performs the lottery according to which range of values the random number generated by the random number generating means 33 indicates. The correspondence between the range of the random number value and the lottery result information indicating the contents of the prize is stored in advance in the lottery table in the storage unit 32.

Here, the fraudster pays attention to the fact that the range of the random number value corresponding to the winning is fixed to a specific area in the period of the number counted as described above, and combines the phase with that period. By depressing the start lever 13, it is possible to aim for a specific winning content.
In the following, a more detailed description will be given using an example of fraudulent acts by solenoid goto.
The fraudster attaches the fraudulent device related to the solenoid got to the start lever 13 of the slot machine 1 and uses this device to start the start lever 13 at the same cycle as the count cycle of the IC counter in the random number generating means 33. Press. That is, by using an unauthorized device, it is possible to press the start lever 13 in synchronization with the same phase in the count cycle every time. In addition, by enabling fine adjustment to slightly delay or advance the timing, it is possible to gradually approach a specific winning content.

  Therefore, by using this fraudulent device, for example, when the start lever 13 is pressed and the result of the internal lottery is “losing”, the random number is a value between 5001 and 16000 in the example of FIG. Therefore, by gradually shifting the timing of depressing the start lever 13, it is possible to approach the area direction of replay or BB. Once the phase can be adjusted to the winning area, the same winning contents can be repeatedly applied by maintaining the phase thereafter.

As shown in FIG. 6, the start signal delay means (signal delay means) 35 is a clock signal output circuit 35-1 for outputting an indefinite period clock signal, and a delay for outputting the input start signal at the input timing of the clock signal. Circuit 35-2.
The clock signal output circuit 35-1 includes a first oscillation circuit 35-11, a second oscillation circuit 35-12, a third oscillation circuit 35-13, a fourth oscillation circuit 35-14, and a first indefinite period clock. It has a generation circuit unit 35-15 and a second indefinite period clock generation circuit unit 35-16.

The first to fourth oscillation circuit units 35-11 to 35-14 oscillate (generate) a waveform signal (oscillation signal) having a periodicity such as a triangular wave, a square wave, a sine wave, or a sawtooth wave, for example. ·Output. Note that the oscillation signal may have no periodicity.
The first to fourth oscillation circuit units 35-11 to 35-14 can be configured to oscillate signals having similar waveforms, or can be configured to oscillate signals having different waveforms. .

However, in order to make the clock signals output from the first and second indefinite period clock generation circuit units 35-15 and 35-16 have an indefinite period, the first oscillation circuit unit 35-11 and the second oscillation circuit unit 35- 12. It is desirable that the third oscillation circuit unit 35-13 and the fourth oscillation circuit unit 35-14 output signals having different waveforms.
In the present embodiment, the frequency of the signal oscillated from all or part of the first to fourth oscillation circuit units 35-11 to 35-14 can be set to 2 [Hz].
In the present embodiment, the first to fourth oscillation circuit units 35-11 to 35-14 are collectively referred to as “signal generation circuit unit A”.

The first and second indefinite period clock generation circuit units 35-15 and 35-16 generate clock signals using the oscillation signals sent from the first to fourth oscillation circuit units 35-11 to 35-14. To the delay circuit 35-2.
The first indefinite cycle clock generation circuit unit 35-15 and the second indefinite cycle clock generation circuit unit 35-16 can be configured to generate and output clock signals having similar waveforms, or different waveforms. The clock signal can be generated and output.

However, it is desirable that the first indefinite cycle clock generation circuit unit 35-15 and the second indefinite cycle clock generation circuit unit 35-16 generate and output clock signals in different bands, respectively.
For example, the first indefinite cycle clock generation circuit unit 35-15 generates and outputs a low frequency clock signal, while the second indefinite cycle clock generation circuit unit 35-16 generates and outputs a high frequency clock signal. be able to.

As described above, the two indefinite-period clock generation circuit units 35-15 and 35-16 output clock signals of different bands, so that the delay circuit 35-2 (the first and second delay circuit units 35-21 and 35-21). 35-22 (described later), the start signal can be delayed and output twice at different timings, so that the periodicity of the start signal can be further eliminated.
In the present embodiment, “high frequency” and “low frequency” simply indicate whether the frequency (or period) of the two clock signals is “higher” or “lower” than the other. Only. In other words, the two clock signals have different frequencies (or periods). For this reason, the meaning and application differ from “high frequency” and “low frequency” used in the information communication field, the power field, and the like.
Further, a clock signal of 100 [Hz] to 1 [kHz] is supplied to the low frequency indefinite period clock generation circuit unit 35-15, and 1 [kHz] is input to the indefinite period clock generation circuit unit 35-16 for high frequency. ] [10 kHz] clock signals can be generated and output, respectively.

  These first and second indefinite period clock generation circuit units 35-15 and 35-16 can output a pulse wave as a clock signal, but do not use a crystal oscillator whose oscillation period is very stable, instead. In addition, it is possible to use an electronic component (electronic element) such as a resistor whose temperature characteristics are not good, or to supply a power source (for example, a household power source) with low voltage value stability. Thereby, the generation period of the pulse wave can be further indefinite.

In addition, the fraudster duplicates (copies) the board on which the first to fourth oscillation circuit units 35-11 to 35-14 and the first and second indefinite period clock generation circuit units 35-15 and 35-16 are mounted. Even if it is used for fraudulent acts, it cannot be synchronized with the period of the pulse wave oscillated from the substrate provided in the slot machine 1.
This is because the cause of the indefinite period of generation of the pulse wave is not due to artificial or mechanical control or operation, but depends on natural phenomena or unstable physical characteristics. This is because it is very difficult to create a state and it is impossible to predict changes.

The delay circuit 35-2 includes a first delay circuit unit 35-21 and a second delay circuit unit 35-22.
When the first and second delay circuit units 35-21 and 35-22 receive the start signal, the first and second delay circuit units 35-21 and 35-22 receive the clock signals transmitted from the first or second indefinite period clock generation circuit units 35-15 and 35-16. The start signal is output according to the input timing.
In other words, in the first and second delay circuit sections 35-21 and 35-22, when a start signal is input, the start signal is not passed as it is, but after waiting for the timing at which the clock signal is input. It is designed to output. For this reason, the first and second delay circuit sections 35-21 and 35-22 can delay the time when the start signal reaches the random number generation means 33.

As a result, even if the fraudster tries to synchronize the timing of pressing the start lever 13 with the timing of winning the winning prize in the internal lottery, the start signal is generated after the start lever 13 is pressed. Since it reaches 33, the winning contents cannot be won.
In addition, since the generation period of the clock signal is indefinite, the delay times of the start signal before the previous time, this time, and the next time are different. For this reason, even if the fraudulent person adjusts the timing of pressing the start lever 13 in consideration of the delay time of the start signal and wins the winning contents, the next time at the same timing (same cycle) Even if the start lever 13 is pressed, it cannot be synchronized with the winning timing.

  In FIG. 6, four oscillation circuit sections and two indefinite period clock generation circuit sections and delay circuit sections are provided (first to fourth oscillation circuit sections 35-11 to 35-14). , First and second indefinite cycle clock generation circuit units 35-15, 35-16, first and second delay circuit units 35-21, 35-22), their oscillation circuit units, indefinite cycle clock generation circuit units, delay The number of circuit portions is not limited to four or two. As shown in FIG. 7, one or two circuit portions (first oscillation circuit portion 35-1A1, second oscillation circuit portion 35) are provided. -1A2), each of the indefinite period clock generation circuit unit and the delay circuit unit (indefinite period clock generation circuit unit 35-10, delay circuit unit 35-20) can be provided. Three or more oscillation circuit units, indefinite period clock generation circuit units, and delay circuit units may be provided.

However, as shown in FIG. 6, if a plurality of oscillation circuit units, indefinite period clock generation circuit units, and delay circuit units are provided, the start signal has a higher periodicity than when one is provided. It can be eliminated further. For this reason, it is possible for the fraudster to make it more difficult to predict the delay time of the start signal.
In FIG. 7, when only one oscillation circuit unit is provided (only the first oscillation circuit unit 35-1A1), an oscillation signal oscillated by the first oscillation circuit unit 35-1A1 or indefinite One or both of the clock signals output from the periodic clock generation circuit unit 35-10 need to have an indefinite period.

[Start signal delay circuit (signal delay device)]
Next, a specific circuit configuration of the start signal delay circuit (signal delay device) in the gaming machine (slot machine) of the present embodiment will be described with reference to FIG.
FIG. 2 is an electronic circuit diagram showing a circuit configuration of the start signal delay circuit.
As shown in the figure, the start signal delay circuit 35 includes first to fourth oscillation circuit units 35-11 to 35-14 and first and second indefinite period clocks corresponding to the components shown in FIG. It has generation circuit sections 35-15 and 35-16, and first and second delay circuit sections (IC10 and IC20) 35-21 and 35-22.

The first oscillation circuit unit 35-11 includes operational amplifiers AP11 and AP12, resistors R11 to R16, and capacitors C11 to C13.
The operational amplifier AP11 forms a square wave oscillation circuit together with the resistor R13 and the like, and oscillates a square wave. The frequency of the square wave output from the operational amplifier AP11 is determined by the resistors R13, R14, R15, and the capacitor C13.
The resistors R11 and R12 divide a voltage (for example, + 5V). This divided voltage is applied to the negative terminal side of the operational amplifier AP11.
The capacitor C11 stabilizes the voltage divided by the resistors R11 and R12.
The resistor R13 is a resistor for positive feedback of the operational amplifier AP11.

The operational amplifier AP12 constitutes an integration circuit together with the capacitor C13 and the like, and receives a square wave from the operational amplifier AP11 on the negative terminal side and outputs a triangular wave. The output triangular wave is sent to the first indefinite period clock generation circuit unit 35-15 through the resistor R16.
The capacitor C13 determines the period of the triangular wave output from the operational amplifier AP12.

The second oscillation circuit unit 35-12 includes an operational amplifier AP21, resistors R21 to R24, a capacitor C21, and a diode D21.
The operational amplifier AP21 forms a square wave oscillation circuit together with the resistor R21 and the like, and oscillates a square wave. The frequency of the square wave output from the operational amplifier AP21 is determined by the resistors R21, R22, R23 and the capacitor C22.
A voltage divided by the resistors R11 and R12 is applied to the negative terminal side of the operational amplifier AP21.
Capacitor C21 stabilizes the voltage divided by resistors R11 and R12.
The resistor R21 is a resistor for positive feedback of the operational amplifier AP21.

The first indefinite period clock generation circuit unit 35-15 includes an operational amplifier AP22, resistors R23 and R24, a capacitor C22, and a diode D21.
The operational amplifier AP22 constitutes an integration circuit together with the capacitor C22 and the like, and inputs a signal indicating the sum of the square wave from the operational amplifier AP21 and the triangular wave from the operational amplifier AP12 on the negative terminal side and outputs the triangular wave.
Capacitor C22 determines the period of the triangular wave output from operational amplifier AP22.

The capacitor C22, the resistors R23 and R24, and the diode D21 are involved in forming the waveform of the clock signal output from the first indefinite period clock generation circuit unit 35-15.
The capacitor C22 is charged / discharged by the output from the operational amplifier AP21 or the output from the operational amplifier AP12.
When the capacitor C22 is charged by the output from the operational amplifier AP21, the output passes through the resistor R23. On the other hand, when the capacitor C22 is discharged by the output from the operational amplifier AP21, it passes through the resistor R23, the resistor R24, and the diode D21. Thus, since the current at the time of discharging is larger than the current at the time of charging the capacitor C22, the discharging time is shorter than the charging time. For this reason, also in the waveform of the clock signal generated by the charging and discharging, the time for outputting the high level is longer than the time for outputting the low level.

  The resistors R23 and R24 and the diode D21 are involved in both the formation of the square wave in the operational amplifier AP21 and the formation of the clock signal output from the first indefinite period clock generation circuit unit 35-15. It belongs to both the oscillation circuit unit 35-12 and the first indefinite period clock generation circuit unit 35-15.

IC1 is connected to the output path of the first indefinite period clock generation circuit unit 35-15.
IC1 is an inverter for adjusting the logic of the circuit (inverted by NOT). Specifically, the clock signal sent from the first indefinite period clock generation circuit unit 35-15 is inverted.

The IC 10 (first delay circuit unit 35-21) can use a D-flip-flop, and constitutes the first delay circuit unit 35-21.
The IC 10 inputs a start signal at a D terminal (input terminal) and a clock signal at a CK terminal (clock terminal). The IC 10 outputs a start signal from the Q terminal (output terminal) in synchronization with the input timing of the clock signal.
The IC 10 is provided with a Q-bar terminal that inverts and outputs the logical value of the start signal, but is not used in this embodiment.

The third oscillation circuit unit 35-13 has the same configuration as the first oscillation circuit unit 35-11.
The fourth oscillation circuit unit 35-14 has the same configuration as the second oscillation circuit unit 35-12.

The second indefinite cycle clock generation circuit unit 35-16 has substantially the same configuration as the first indefinite cycle clock generation circuit unit 35-15.
However, the first indefinite cycle clock generation circuit unit 35-15 and the second indefinite cycle clock generation circuit unit 35-16 have different capacities of the capacitor C22 and the capacitor C42, respectively.
By making the capacitances of the capacitors C22 and C42 different, the output timing of the clock signal output from the first indefinite cycle clock generation circuit unit 35-15 or the second indefinite cycle clock generation circuit unit 35-16 is different. Can be made. For this reason, the time which delays a start signal by the 1st delay circuit part 35-21 and the 2nd delay circuit part 35-22 can each differ. Thereby, the delay time of the start signal can be made more indefinite.

The IC 20 (second delay circuit unit 35-22) can use a D-flip flop.
The IC 20 inputs the start signal output from the Q terminal of the IC 10 at the D terminal (input terminal) and the clock signal at the CK terminal (clock terminal). The IC 20 outputs a start signal from the Q terminal (output terminal) in synchronization with the input timing of the clock signal.
The IC 20 is provided with a Q bar terminal that inverts and outputs the logical value of the start signal, but is not used in this embodiment.

Next, the waveforms of signals at various points in the start signal delay circuit will be described with reference to FIGS.
In the figure, points A to D correspond to points A to D in the start signal delay circuit 35 shown in FIG. That is, the point A is the output of the operational amplifier AP12, the point B is the output of the operational amplifier AP22, the point C is the output of the first indefinite period clock generation circuit unit 35-15, and the point D is the output of the IC1. Indicates a point.
Moreover, FIG. 9A and FIG. 9B show the difference in waveform due to the difference in timing of taking the waveform while keeping the same time axis. FIG. 4C shows waveforms when the time axis is set longer than those in FIG. 4A and FIG.

First, looking at the waveform at point B in FIG. 5A, this waveform is an output from the operational amplifier AP22 and is a triangular wave (sawtooth wave). This is because a signal (waveform at point C) formed by charging / discharging of the capacitor C22 is input to the negative terminal side of the operational amplifier AP22 constituting the integrating circuit.
The capacitor C22 constituting the integration circuit is charged and discharged by the output from the operational amplifier AP21. The rising portion of the triangular wave, which is the waveform at point B (the output from the operational amplifier AP22), the discharge of the capacitor C22, and the triangular wave And the charging of the capacitor C22 correspond to each other.

Next, looking at the waveform at point C in FIG. 5A, this waveform is an output of the first indefinite period clock generation circuit unit 35-15, and is a square wave and a clock signal.
The waveform at this point C is formed in accordance with charging / discharging of the capacitor C22. That is, when charging is performed with the output from the operational amplifier AP21, the waveform at the point C is at a high level, while when discharging with the output from the operational amplifier AP21, the waveform at the point C is at a low level. At this time, the current for charging the capacitor C22 passes through the resistor R23, while the current discharged from the capacitor C22 passes through the resistors R23 and R24. For this reason, the discharge time is shorter than the charge time.

Further, looking at the waveform at point D in FIG. 5A, the waveform is inverted as compared with the waveform at point C. This is because IC1 is a NOT circuit.
The waveform at this point D becomes a clock signal, that is, a pulse wave, and is input to the CK terminal of the IC 10 (first delay circuit unit 35-21).

Note that the waveform at point A in FIG. 5A is an output from the operational amplifier AP12, and thus is a triangular wave originally, but since the time axis is shortened, it appears only in a straight line. On the other hand, the waveform at point A in FIG. 4C appears as a triangular wave because the time axis is lengthened.
The waveform at point A (the output of the operational amplifier AP12 (triangular wave)) is added to the output (square wave) from the operational amplifier AP21, and is charged and discharged by the capacitor C22. Further, since the waveform at the point A is a triangular wave, the value gradually changes. As a result, the time during which the capacitor C22 discharges gradually changes. For this reason, the rising or falling intervals indicated by the waveforms at points C and D in FIGS. 7A and 7B are not constant. For this reason, as shown in (a) and (b) of the figure, the rising or falling intervals of the waveforms at the point C and the point D are different at the timing of taking the waveform.
In the present embodiment, the delay time of the start signal is made indefinite by using the fact that the rising or falling intervals of the waveforms at the points C and D are gradually converted, thereby making it possible to protect against illegal acts.
It should be noted that the waveforms at point C and point D in FIG. 5C cannot be measured because the time axis is long.

The start signal delay means described in the present embodiment is provided in the control means in FIG. 4, but the start signal delay means is not limited to being provided in the control means. As another example, the control unit may be provided separately.
In this case, the signal delay device is configured to input the start signal and output the start signal at the timing when the clock signal is input.

However, the gaming machine and the signal delay device according to the present invention are not limited to the above-described embodiments, and various modifications can be made within the scope of the present invention. Needless to say, it is possible to implement this change.
For example, in the above-described embodiment, the start signal is delayed by the flip-flop. However, the start signal is not limited to the flip-flop. For example, the start signal can be delayed by using a household power supply whose voltage value is not stable.
