A random number circuit 42 for generating a signal, a pulse oscillator 43 for supplying a clock signal of a constant frequency to the random number circuit 42, and a detection signal input from a switch connected directly to the game control board 40 or via the power supply board 101. Switch detection circuit 44, motor drive circuit 45 that controls the drive of the reel motors 32L, 32C, and 32R, solenoid drive circuit 46 that controls the drive of the flow path switching solenoid 30, various displays and LEDs connected to the game control board 40 LED drive circuit 47 for controlling the driving of the power supply power supplied to the slot machine 1 When a voltage drop is detected, a power interruption detection circuit 48 that outputs a voltage drop signal indicating that to the main control unit 41, when the power is turned on or when an initialization command is not input from the main CPU 41a In addition, a reset circuit 49 for supplying a reset signal to the main CPU 41a and other electronic components such as various devices and circuits are mounted.

  The main CPU 41a has an interrupt function (including an interrupt prohibition function) such as a timekeeping function and a timer interrupt, executes a program (described later) stored in the ROM 41b, and performs processing related to the progress of the game. Each part of the control circuit mounted on the game control board 40 is controlled directly or indirectly. The ROM 41b stores fixed data such as programs executed by the main CPU 41a and various tables. The RAM 41c is used as a work area when the main CPU 41a executes a program. The I / O port 41d inputs / outputs a control signal to / from each circuit connected via a signal input / output terminal included in the main control unit 41.

  Further, the main control unit 41 is supplied with backup power even during a power failure, and the data stored in the RAM 41c is held while the backup power is being supplied.

  The main CPU 41a repeatedly loops the process according to the control state until the detection state of the various switches connected to the game control board 40 is changed as a basic process, and step by step according to the change of the detection state of the various switches. Execute the process to move to. Further, the main CPU 41a has an interrupt function as described above, and can interrupt the basic process by the occurrence of the interrupt and execute the interrupt process. The voltage output from the power interruption detection circuit 48 The power interruption interrupt process (main) is executed in response to the input of the decrease signal, and the timer interrupt process (main) is executed at regular time intervals (about 0.56 ms in this embodiment). In addition, the execution interval of the timer interrupt process (main) is set to a time longer than the sum of the time required to complete the repeated process according to the control state in the basic process and the execution time of the timer interrupt process (main) Therefore, the process that is repeated according to the control state between the current and next timer interrupt processes (main) is completed at least once.

  The main CPU 41a transmits various commands to the effect control board 90 via the I / O port 41d. A command transmitted from the game control board 40 to the effect control board 90 is sent in only one direction, and no command is sent from the effect control board 90 to the game control board 40. The transmission line of the command transmitted from the game control board 40 to the effect control board 90 is composed of a strobe (INT) signal line, a data transmission line, and a ground line, and is connected via the effect relay board 80. The game control board 40 and the effect control board 90 are not directly connected.

  The effect control board 90 is connected to effect devices such as a liquid crystal display 51 (see FIG. 1), an effect LED 52, speakers 53 and 54, and the reel LED 55 described above, which are arranged on the front door 1b of the slot machine 1. These effect devices are driven based on control by a later-described sub-control unit 91 mounted on the effect control board 90.

  In this embodiment, the sub-control unit 91 mounted on the effect control board 90 controls the output of the effect devices such as the liquid crystal display 51, effect effect LED 52, speakers 53 and 54, and reel LED 55. However, in addition to the sub-control unit 91, an output control unit that directly controls the output of the effect device is mounted on the effect control board 90 or another board, and the sub-control unit 91 is based on a command from the main control unit 41. The output control unit may determine the output pattern of the effect device, and the output control unit may control the output of the effect device based on the output pattern determined by the sub control unit 91. In such a configuration, the sub control unit 91 and the output control may be performed. The output control of the rendering device is performed by both of the units.

  Further, in the present embodiment, the liquid crystal display 51, the effect effect LED 52, the speakers 53 and 54, and the reel LED 55 are exemplified as the effect device, but the effect device is not limited to these, for example, a mechanically driven display. A device or a mechanically driven item may be applied as the effect device.

  Similar to the main control unit 41, the effect control board 90 includes a sub CPU 91a, ROM 91b, RAM 91c, and a microcomputer provided with an I / O port 91d. The sub control unit 91 controls the effect, and the effect control board 90. A display control circuit 92 that performs display control of the liquid crystal display 51 connected to the LED, an LED driving circuit 93 that performs drive control of the effect LED 52 and the reel LED 55, an audio output circuit 94 that controls audio output from the speakers 53 and 54, Supplied to a reset circuit 95 that gives a reset signal to the sub CPU 91a when the power is turned on or when an initialization command from the sub CPU 91a is not inputted for a certain period of time, a clock device 97 that outputs time information including date information and time information, and a slot machine 1 The power supply voltage is monitored, and when a voltage drop is detected, this is indicated The power interruption detection circuit 98 that outputs a pressure drop signal to the sub CPU 91a, other circuits, and the like are mounted. The sub CPU 91a receives a command transmitted from the game control board 40 and performs an effect. While performing various controls, each part of the control circuit mounted on the effect control board 90 is controlled directly or indirectly.

  Similar to the main CPU 41a, the sub CPU 91a has an interrupt function (including an interrupt prohibition function). One of the interrupt terminals of the sub control unit 91 is connected to a strobe (INT) signal line that is output when the main control unit 41 transmits a command, among the command transmission lines, and the sub CPU 91a receives the strobe signal. An interrupt is generated based on the input to acquire a command from the main control unit 41 and execute a command reception interrupt process to be stored in the buffer. Further, the sub CPU 91a executes an interrupt process (sub) to be described later by generating an interrupt every time the number of clock inputs reaches a certain number, that is, every certain interval. One of the interrupt terminals of the sub-control unit 91 is connected to the power interruption detection circuit 98, and the sub CPU 91a responds to the input of the voltage drop signal output from the power interruption detection circuit 98. Execute processing (sub). Further, when an unused interrupt occurs in the sub CPU 91a, an unused interrupt process for immediately returning to the original process is executed.

  The sub-control unit 91 is also supplied with backup power at the time of a power failure, and the data stored in the RAM 91c is held while the backup power is supplied.

  In the slot machine 1 of the present embodiment, various boards such as the game control board 40 provided with the main control unit 41 for controlling the game are mounted as described above, and these boards are shown in FIG. As described above, electrical components such as switches that can be operated by a player are connected via a cable.

  As described above, on the game control board 40, the single BET switch 5, the MAXBET switch 6, the start switch 7, the stop switches 8L, 8C, 8R, the insertion medal sensor 31, the reel motors 32L, 32C, 32R, and the reel sensor 33L. 33C, 33R, a hopper motor 34b, a payout sensor 34c, and an effect control board 90 are connected.

  Specifically, as shown in FIG. 4, the start switch 7 is connected to the game control board 40 by wiring, and the one-sheet BET switch 5, the MAXBET switch 6, the stop switches 8L, 8C, 8R, the insertion medal sensor 31, and the door open. The detection switch 25 is connected to the game control board 40 via the operation unit relay board 110, and the reel motors 32L, 32C, 32R and the reel sensors 33L, 33C, 33R are used for game control via the reel relay board 120. The hopper motor 34b and the payout sensor 34c are connected to the game control board 40 via the power supply board 101, and the effect control board 90 is connected to the game control board 40 via the effect relay board 80. And wired connection.

  The operation unit relay board 110, the reel relay board 120, the power supply board 101, and the effect control board 90 are provided with wiring patterns (not shown) for connecting the game control board 40 and each electrical component. The detection signal output from the component to the game control board 40 or the power or signal supplied (input) from the game control board 40 can be relayed.

  In this way, various electrical components except the start switch 7 and the game control board 40 are routed through the relay boards 110, 120, and 80 attached to predetermined positions of the main body of the slot machine 1 (the casing 1a in this embodiment). Thus, the wiring connection between the game control board 40 and a plurality of electrical components individually arranged at predetermined locations of the main body of the slot machine 1 is facilitated, and the connector connection portion is always connected to the relay board or the game. Since it is provided on the control board 40, and the connector connection portion of each electrical component is thereby fixed, it is possible to prevent the connector connection portion from being searched for during the wire connection work or the wrong type of wiring to be connected. The

  Single BET switch 5, MAXBET switch 6, start switch 7, stop switches 8L, 8C, 8R, insertion medal sensor 31, reel motors 32L, 32C, 32R, reel sensors 33L, 33C, 33R, hopper motor 34b, payout sensor 34c Is an electrical component that inputs and outputs signals relating to the progress of the game to and from the game control board 40. 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 2L, 2C, and 2R. Such as signals output to the game control board 40 in accordance with the progress of the game, detection of inserted medals, detection of the reference position of the reels, detection of the payout medals, etc., output from the electrical components for gaming according to the progress of the game And a signal input to the game control board 40, a drive signal for driving the reels 2L, 2C, 2R according to the detection of the start operation, and a hopper for paying out medals when a winning occurs. A signal that is output from the game control board 40 in accordance with the progress of the game and that is input to the game electrical component, such as a drive signal.

  These gaming electrical components are a first electrical component that outputs a signal to the game control board 40 as the game progresses, and a second that receives a signal from the game control board 40 as the game progresses. And electric parts.

  The gaming electrical component and the board are connected via a cable, and the cable connecting the gaming electrical component and the board is designed to facilitate assembly work and wiring work during manufacturing of the slot machine. Separation is possible by releasing the connection. In addition, these electrical parts for gaming are basically electrical parts that continue to be used in common for multiple models, and there are few opportunities to remove them from the main body and replace them unless a failure occurs. It is fixed in place. On the other hand, the game control board 40, the effect control board 90, and the like need to be replaced when changing the model, and are removed from the main body at that time. In other words, when removing the game control board 40, it is necessary to release the connection between the game electrical parts and the effect control board 90, so the cables and boards that connect these boards and the board and the game electrical parts are The cable side connector provided at the end of the cable is electrically connected to the board side connector electrically connected to the wiring pattern of the board, and the cable side connector is removed from the board side connector. By releasing the connection, the game control board 40 can be easily removed from the main body and replaced.

  However, when the slot machine is shipped from the manufacturer to the game store in such a state that the wiring connection between the game control board 40 and the electrical component for gaming can be easily released by removing the connector, for example, in the game store, the board side connector In this case, the cable-side connector can be easily removed from the board-side connector, and the cable-side connector connected to an unauthorized tool such as a so-called driving tool can be easily connected to the board-side connector.

  The driving instrument is, for example, a switch that is provided in the slot machine by causing the game control board 40 to input / output a signal that simulates a signal input / output to / from the game control board 40 from an electrical component for gaming. The game can be automatically advanced without operation. Therefore, for example, in a game store or the like, the regular connector connected to the board-side connector provided on the game control board 40 is removed, and an unauthorized connector connected to the driving tool is connected instead. By inputting / outputting signals to / from the game control board 40 at an appropriate timing to automatically advance the game, for example, it is possible to easily set a state where a special role is won. Therefore, the slot machine set in such a state that the special role is won using such an illegal driving tool, and further, the RB having a higher advantage among the RB and BB is set to be highly likely to be won. In the case where illegal sales such as providing a slot machine to a player at the start of business at a game store or the like is carried out, there is a risk that the fairness of the game will be impaired.

  For this reason, in this embodiment, as described above, only the start switch 7 of the electrical components for gaming is directly connected to the game control board 40, and the connector connection between the game control board 40 and the start switch 7, that is, Regarding the connection between the board-side connector 620b of the game control board 40 and the cable-side connector 610b of the cable 600b and the connection between the component-side connector 640b of the start switch 7 and the cable-side connector 630b, the connection between the connectors is released. Can be regulated by.

  Here, the connector restricting member 650 for restricting the release of the connection between the board-side connector 620b and the cable-side connector 610b of the cable 600b is, for example, as shown in FIG. 5, a main body 650a formed in a box shape whose one surface is open. And a cylindrical attachment portion 650b provided integrally with the side portion of the main body portion 650a and having an engagement hole 650c formed on the outer periphery of the lower end, and connected to the board-side connector 620b. The elastic claw 237a provided in the engagement cylinder 237 is engaged by fitting the attachment section 650b into an engagement cylinder 237 of the upper case 202 described later in a state covered with the main body 650a from above 610b. The upper case 202 is attached to the mating hole 650c.

  By fitting the mounting portion 650b of the connector restricting member 650 into the engagement cylinder 237 in this way, the elastic claw 237a is engaged with the engagement hole 650c in the inside thereof, so that the engagement portion is engaged unless it is destroyed. Since the state cannot be released from the outside, in order to release the connector connection between the game control board 40 and the start switch 7, the release restricting portion must be destroyed, thereby the game control board. When the connector connection between the start switch 7 and the start switch 7 is released, the trace remains and it is extremely difficult to erase the trace. Therefore, the illegal business can be more effectively suppressed.

  The connector restricting member 650 for restricting the release of the connection between the component side connector 640b and the cable side connector 630b of the start switch 7 is not particularly shown, but is removed unless a predetermined release restricting part related to the release of the connection is destroyed. Anything that can't be done.

  In this embodiment, the game control board 40 and the start switch 7 are connected without going through the relay board, and the connector connection only needs to be made on the game control board 40 and the electrical component (start switch 7) side. Wiring connections are simplified, but when connecting via one or more relay boards, it is preferable to regulate the removal of all connector connections that exist between them. Since it becomes difficult to release the connection of any of the connectors between the game control board 40 and the start switch 7, the illegal business can be prevented more effectively.

  In the present embodiment, the first electric components 5, 6, 7, 8, 31, 33L, 33C, 33R, and 35 that input signals to the game control board 40 in accordance with the progress of the game and the progress of the game. Of the second electrical components 32L, 32C, 32R, 34 for which a signal is output from the game control board 40 in response to this, a connector restricting member 650 is provided only for connector connection between the start switch 7 and the game control board 40. The release of connection between connectors is regulated. In other words, the connector connection between the start switch 7 (the game cannot be started unless the signal from the start switch 7 is input) and the game control board 40 cannot advance the game without the signal. Even when the connector restricting member 650 is provided to restrict the release of the connection between the connectors, even when the connection between the other electrical components and the game control board 40 is released and replaced with the connector of the driving tool. Since the game cannot be substantially automatically advanced, it is possible to prevent an illegal act with a minimum restriction, and to reduce the number of parts for releasing the connection between these connectors.

  In this embodiment, only the connector connection between the start switch 7 and the game control board 40 is provided with the connector restriction member 650 to restrict the release of the connection between the connectors, but the inserted medal sensor 31 and the game control board The same effect can be obtained by providing a connector restricting member only for connector connection between the connectors 40 and restricting the release of the connection between the connectors. Further, if the reel is not configured to stop until the reel stop operation is performed after the start of the reel rotation as in the present embodiment, between the stop switch 8L, 8C, 8R and the game control board 40. The same effect can be obtained even if the connector restricting member is provided only for the connector connection to restrict the release of the connection between the connectors.

  In this embodiment, the door opening detection switch 25 is connected to the game control board 40 via a cable. However, any of the connectors of the cable provided between the door opening detection switch 25 and the game control board 40 may be used. When the connection at that connector is released, when the front door 1b is opened, the main control unit 41 mounted on the game control board cannot detect that fact, and the door opening notification or door opening is detected. Since the output of the signal is not performed, the discovery may be delayed even if the front door 1b is opened and an illegal act is performed. Therefore, the connector connection between the game control board 40 and the door opening detection switch 25 is not possible. A connector restricting member may be provided to restrict the release of the connection between the connectors. By doing so, the game control board 40 and the door opening detection switch 25 may be restricted. It becomes difficult to release the one of connector connection between, with no been informed to the effect that the opening of the front door 1b, can be effectively prevented front door 1b from being opened.

  Further, in this embodiment, a plurality of signal lines connecting the main control unit 41 and a plurality of electrical components other than the start switch 7 for inputting and outputting signals necessary for the progress of the game and the door opening detection switch 25 are provided. Since the game control board 40 and the operation unit relay board 110 are connected by a single cable 600a, the connector connection between the board-side connector 620a and the cable-side connector 610a of the game control board 40, that is, one connector By restricting the release of only the connection, it becomes possible to restrict the release of the connection between the signal lines, and it is not necessary to prepare multiple parts for restricting the release of these connector connections. The score can be reduced.

  When a plurality of signal lines connecting the main control unit 41 and a plurality of electrical components for inputting / outputting signals necessary for the progress of the game and the door opening detection switch 25 are connected via a plurality of cables. However, in order to regulate the release of these connector connections by arranging the board side connectors close to each other and restricting the release of the connection between the plurality of board side connectors and the plurality of cable side connectors with one component. It is not necessary to prepare a plurality of parts, and the number of these parts can be reduced.

  The slot machine 1 of this embodiment outputs an external output signal indicating a gaming state, an error occurrence state, and the like. These external output signals are output from the game control board 40 under the control of the main CPU 41a, and the hall computer is provided via the external output board 1000 and the information providing terminal board (not shown) of the game store (hall) where the slot machine 1 is installed. It is output to hall equipment such as (not shown).

  From the game control board 40 to the external output board 1000, a medal IN signal indicating the number of medals used for setting the number of bets, a medal OUT signal indicating the number of medals given to the player due to the occurrence of a winning, a gaming state RB signal indicating that RB is described later, a BB signal indicating that the gaming state is BB described later, a door opening signal indicating that the front door 1b is open, and a setting change mode described later. A setting change signal indicating that the medals are in error, an insertion error signal indicating an abnormality in the medal selector, and a payout error signal indicating an abnormality in the hopper unit 34 are output.

  In the slot machine 1 of the present embodiment, the medal payout rate changes according to the set value. Specifically, the medal payout rate is changed by using a winning probability corresponding to a set value in an internal lottery described later. The set value is composed of 6 levels of 1 to 6, with 6 being the highest payout rate and the payout rate being lower as the value is decreased in the order of 5, 4, 3, 2, 1. That is, when 6 is set as the set value, the advantage is highest for the player, and as the value decreases in order of 5, 4, 3, 2, 1, the advantage decreases stepwise.

  In order to change the setting value, it is necessary to turn on the power of the slot machine 1 after the setting key switch 37 is turned on. When the setting key switch 37 is turned on and the power is turned on, the setting value read from the RAM 41c is displayed on the setting value display 24 as a display value, and the setting value can be changed by operating the reset / setting switch 38. Transition to the setting change state. When the reset / setting switch 38 is operated in the setting change state, the display value displayed on the setting value display 24 is updated one by one (when further operation is performed from the setting 6, the display returns to the setting 1). . When the start switch 7 is operated, the display value is determined as the set value. Then, when the setting key switch 37 is turned OFF, the determined display value (setting value) is stored in the RAM 41c of the main control unit 41, and the state shifts to a state in which the game can proceed.

  In order to confirm the set value, after the game is over, the setting key switch 37 may be turned on with no bet amount set. When the setting key switch 37 is turned on in such a situation, the setting value read out from the RAM 41c is displayed on the setting value display 24, thereby shifting to a setting confirmation state in which the setting value can be confirmed. In the setting confirmation state, the game cannot be progressed, and by turning the setting key switch 37 to the OFF state, the setting confirmation state is ended and the state in which the game can proceed is returned.

  In the slot machine 1 of the present embodiment, when the main CPU 41a detects a voltage drop signal from the power interruption detection circuit 48, a power interruption interrupt process (main) is executed. In the power interruption interrupt processing (main), the register is saved in a stack of a RAM 41c, which will be described later, and data for destructive diagnosis (in this embodiment, 5AH) in which any bit becomes 1, that is, a specific value other than 0 In addition to storing data, the RAM parity adjustment data is calculated so that the RAM parity based on the data stored in all areas of the RAM 41c is 0, and the RAM 41c is stored. The RAM parity is a value calculated as an exclusive OR of values stored in each bit of the corresponding area (all areas in this embodiment) of the RAM 41c. Therefore, if the RAM parity based on the data stored in all areas of the RAM 41c is 0, the RAM parity adjustment data is 0, and the RAM parity based on the data stored in all areas of the RAM 41c is 1. In this case, the RAM parity adjustment data is 1.

  The main CPU 41a calculates the RAM parity based on the data stored in all areas of the RAM 41c at the time of activation, confirms the value of the destructive diagnosis data, the RAM parity is 0, and the destructive diagnosis The processing state of the main CPU 41a is restored to the state before the power interruption based on the data stored in the RAM 41c on the condition that the value of the data for use is correct, but the RAM parity is not 0 (in the case of 1) or is destroyed. If the value of the diagnostic data is not correct, it is determined that the RAM is abnormal, and the RAM abnormal error code is set in the register to control the RAM abnormal error state so that the progress of the game is disabled. Unlike the other error states, the RAM abnormal error state is not canceled even if the reset switch 23 or the reset / setting switch 38 is operated, and a new set value is set in the setting change state described above. It will not be released until

  In this embodiment, all the data stored in the RAM 41c is held by the backup power source even in the event of a power failure, and when the main CPU 41a determines that the data in the RAM 41c is normal when the power is turned on. Although the configuration is such that the control state before power interruption is restored based on the data stored in the RAM 41c, only the data necessary for the restoration of the control state in the event of a power failure is backed up among the data stored in the RAM 41c. It may be configured to return to the control state before power interruption based on the backed up data.

  In addition, when returning to the control state before the power interruption when the power is turned on, it is not necessary to return all the control states to the control state before the power interruption, and the minimum control state that does not disadvantage the player For example, it is not necessary to restore the state of all input ports to the state before power interruption.

  In addition, when the sub CPU 91a detects the voltage drop signal from the power interruption detection circuit 98, the sub CPU 91a also executes a power interruption interrupt process (sub). In the power interruption interrupt processing (sub), the register is saved in a stack of a RAM 91c described later, and destructive diagnosis data in which any bit is 1 is stored in the RAM 91c, and data stored in all areas of the RAM 91c. The RAM parity adjustment data is calculated so that the RAM parity based on 0 becomes 0 and stored in the RAM 91c.

  Then, the sub CPU 91a calculates the RAM parity based on the data stored in all areas of the RAM 91c at the time of activation, and based on the data stored in the RAM 91c on the condition that the RAM parity is 0. The processing state of the sub CPU 91a is restored to the state before the power interruption. If the RAM parity is not 0 (1), it is determined that the RAM is abnormal and the RAM 91c is initialized. In this case, unlike the main CPU 41a, the performance is not disabled only by initializing the RAM 91c.

  In this embodiment, all data stored in the RAM 91c is held by the backup power source even during a power failure, and the sub CPU 91a determines that the data in the RAM 91c is normal when the power is turned on. Although the configuration is such that the control state before power interruption is restored based on the data stored in the RAM 91c, only the data necessary for restoration of the control state is backed up in the event of a power failure out of the data stored in the RAM 91c. It may be configured to return to the control state before power interruption based on the backed up data.

  In addition, when returning to the control state before the power interruption when the power is turned on, it is not necessary to return all the control states to the control state before the power interruption, and the minimum control state that does not disadvantage the player It is not necessary to restore the state of the input port or the progress in the middle of the production when it is interrupted. For example, only the data indicating the gaming state such as during the big bonus or the normal gaming state is backed up, and the effect corresponding to the gaming state (the big bonus during the big bonus, the normal during the normal gaming state) If a power interruption occurs during the execution of a specific production (such as a small role announcement) other than the production), when the power is turned on instead of resuming the specific production that was being performed at the next power-on An effect corresponding to the gaming state being backed up may be executed from the beginning.

  Next, initialization of the RAM 41c of the main control unit 41 will be described. The storage area of the RAM 41c of the main control unit 41 is divided into an important work, a general work, a special work, a set value work, a non-saved work, an unused area, and a stack area.

  The important work is a work that stores data that is inconvenient to be initialized at the end of the big bonus, such as various display devices and LED display data, input / output data of the I / O port 41d, and a game time counter. The general work is a work in which data that can be initialized at the end of the big bonus, such as a stop control table, a stop symbol, the number of medals paid out, and the total number of medals paid out in the big bonus, are stored. The special work stores data that is not initialized even before the setting is changed, such as data for transmitting a command to the effect control board 90 and various software random numbers (a random number for determination value addition described later, a random number for changing an initial value). Work. The set value work is a work that stores a set value used when a lottery is performed in the internal lottery process. The unsaved work is a work that holds the state of various switches, and a value is always set regardless of whether or not the data in the RAM 41c is destroyed at the time of activation. The unused area is an unused area in the storage area of the RAM 41c, and is initialized if any one of a plurality of initialization conditions described later is satisfied. The stack area is an area in which data saved from the register of the main CPU 41a is stored, and the unused stack area is established by any one of a plurality of initialization conditions to be described later, like the unused area. In this case, the used stack area is not initialized because the program continues.

  In this embodiment, the main CPU 41a destroys data in the RAM 41c when a RAM abnormality error occurs, when the setting key switch 37 is activated with the setting key switch 37 turned on, when the big bonus is completed, and when the setting key switch 37 is activated with the setting key switch 37 turned off. If not, when five initialization conditions at the end of one game are satisfied, five types of initialization that are initialized in different areas are performed according to each initialization condition.

  Initialization 0 is initialization that is performed when a RAM abnormality error occurs. In initialization 0, all the areas (including the unused area and the unused stack area) of the storage area of the RAM 41c except the used stack area are stored. It is initialized. Initialization 1 is an initialization that is performed before the setting key switch 37 is turned on at the time of startup and shifts to the setting change state. In the initialization 1, a special area in the storage area of the RAM 41c is selected. Areas other than the work, the unsaved work, and the used stack area (including the unused area and the unused stack area) are initialized. Initialization 2 is initialization performed at the end of the big bonus. In initialization 2, the general work, the unused area, and the unused stack area are initialized in the storage area of the RAM 41c. Initialization 3 is initialization that is performed when the setting key switch 37 is in an OFF state at the time of startup and the data in the RAM 41c is not destroyed. The used stack area is initialized. Initialization 4 is initialization performed at the end of one game. In initialization 4, an unused area and an unused stack area in the storage area of the RAM 41c are initialized.

  In this embodiment, initialization 1 is performed before the change of the setting change state. However, the initialization 1 is performed at the end of the setting change state, or both before the change of the setting change state and at the end of the setting change state. Also good. In this case, if the set value work is initialized, the determined set value is lost. Therefore, the initialization of the set value work is not performed in the initialization at the end of the setting change state.

  In the slot machine 1 according to the present embodiment, the prescribed number of bets that can be set according to the gaming state is determined as described above, and the prescribed number of bets that are determined according to the gaming state is set. It becomes possible to start the game on the condition. In the present embodiment, as will be described later, there are regular bonuses (hereinafter referred to as RB) (big bonus (hereinafter referred to as BB)), RT (0) to (6), and among these, RB ( In BB), 1 is defined as the specified number of bets, and in RT (0) to (6), 3 is defined as the specified number of bets. Therefore, if the gaming state is RB (BB), it is possible to start the game when 1 is set as the bet number, and 3 is set as the bet number if RT (0) to (6). Then, the game can be started. In this embodiment, the winning line L is activated when a specified number of bets corresponding to the gaming state is set, and 1 is set as the bet number in RB (BB). All winning lines L1 to L5 are activated at the time when the winning numbers are reached, and all winning lines L1 to L5 are activated when 3 is set as the betting number in RT (0) to (4). It becomes.

  The slot machine 1 according to the present embodiment plays a role on an activated pay line (hereinafter, the activated pay line is simply referred to as a pay line) when all the reels 2L, 2C, 2R are stopped. A winning combination will be awarded when all the combinations of symbols are called. The combination may be a combination of the same symbols or a combination including different symbols. The type of winning combination is determined according to the game state, but it can be roughly divided into a small role with payout of medals and a replay that can start the next game without the need to set the number of bets. There are a game combination and a special combination with a transition of the game state. Below, a small role and a re-playing role are collectively called a general role. In order for winning of each combination determined according to the gaming state to occur, it is necessary to win an internal lottery to be described later and set a winning flag of the combination in the RAM 41c.

  Of these winning flags, the winning flags for the small role and the replaying role are valid only in the game in which the flag is set, and are invalid in the next game. It is valid until a combination of combinations permitted by the flag is completed, and is invalid in a game having a combination of combinations permitted. In other words, once the special combination winning flag is won, even if the combination of the combinations permitted by the flag cannot be made, the winning flag is not invalidated and is carried over to the next game. It becomes.

  In the internal lottery, it is determined whether or not the above winning combination is permitted before the display results of all reels 2L, 2C, and 2R are derived and displayed (actually, when the start switch 7 is detected). To do. In the internal lottery, first, a random number for internal lottery (an integer from 0 to 65535) is acquired. Then, for each combination determined according to the gaming state and whether or not the special combination is carried over, the acquired random number for internal lottery and the number of judgment values for each combination determined according to the gaming state, the number of bets and the set value Is done according to.

  In this embodiment, whether the gaming state is RT (0) (1) (not carrying a special role) or RT (2) (4) (5) (not carrying a special role) Depending on whether it is RT (3) (not carrying over a special combination), RT (6) (while carrying a special combination) or RB (BB), the combination that is subject to internal lottery differs.

  In the internal lottery, the number of determination values determined corresponding to the role to be subject to the internal lottery, the current gaming state and the set value are sequentially added to the random number for the internal lottery, and when the result of addition overflows, It is determined that the winning combination has been won. For this reason, a winning combination will be won with a probability (number of determination values / 65536) according to the number of determination values.

  If a winning combination of any combination is determined, a winning flag corresponding to the combination determined to be winning is set in the internal winning flag storing work assigned to the RAM 41c. The internal winning flag storage work consists of a 2-byte storage area, of which the upper byte is assigned as the special role storing work in which the winning flag for the special role is set, and the lower byte is the winning of the general role It is assigned as a general role storage work for which a flag is set. Specifically, when a special combination is won, a special combination winning flag indicating that the special combination is won is set in the special combination storing work, and the winning flag set in the general combination storing work is cleared. When a general combination is won, a winning flag for the general combination indicating that the general combination is won is set in the general combination storing work. If no winning combination is selected, only the general winning combination work is cleared.

  Next, stop control of the reels 2L, 2C, 2R will be described.

  The main CPU 41a refers to the table index and table creation data stored in the ROM 41b when the reel starts rotating and when the reel stops and the reel that is still rotating still remains. Create a stop control table for each reel. When any of the stop switches 8L, 8C, and 8R corresponding to the rotating reel is effectively detected, the stop control table of the corresponding reel is referred to and the slip of the referred stop control table is referred to. Based on the number of frames, control is performed to stop the rotation of the reels 2L, 2C, 2R corresponding to the operated stop switches 8L, 8C, 8R.

  In the table index, an index that indicates the start address of the area in which the data for table creation is stored, from the reference address when referring to the table index, according to the setting state of the winning flag by internal lottery (hereinafter referred to as the internal winning state) Differences up to the address where the data is stored are registered. As a result, a difference corresponding to the internal winning state is acquired, and the corresponding index data can be acquired by adding the difference to the reference address. Even when the winning combinations are different, when the same control is applied, the same address is stored as the index data. In such a case, the same table creation data is referred to. Thus, a stop control table is created.

  The table creation data includes a stop control table indicating the number of sliding frames according to the stop operation position, and an address of the stop control table to be referred to according to the reel stop status.

  The stop control table referred to according to the reel stop status is whether all reels are rotating, only the left reel is stopped, only the middle reel is stopped, only the right reel is stopped, It may vary depending on whether the middle reel is stopped, the left and right reels are stopped, the middle and right reels are stopped, and if any reel is stopped, stop Since there may be differences depending on the stop position of the reels already completed, the address of the stop control table to be referenced for each situation is registered for each rotating reel, and based on the top address of the table creation data, It is possible to specify the address of the stop control table that should be referred to according to the status of the system. And to be able to identify the stop control table. Even when the reel stop status and the stopped position of the stopped reel are different, when the same stop control table is applied, the same address may be registered as the address of the stop control table. In such a case, the same stop control table is referred to.

  The stop control table is data that can specify the number of sliding frames for each timing when the stop operation is performed. In this embodiment, stepping motors that make one turn at a cycle of 168 steps (0 to 167) are used for the reel motors 32L, 32C, and 32R. That is, when the reel motors 32L, 32C, and 32R are driven for 168 steps, the reels 2L, 2C, and 2R make one round. 21 areas (frames) divided every 8 steps (the number of steps in which one symbol moves) per reel are defined, and these areas are areas 0 to 20 from the reel reference position. A number is assigned. On the other hand, the number of symbols arranged on one reel is 21, and symbol numbers 0 to 20 from the reel reference position are assigned to symbols on each reel, so symbols 0 to 20 are assigned to each reel. , Area numbers 0 to 20 are assigned in order. In the stop control table, the number of sliding symbols for each area number is compressed and stored according to a predetermined rule, and the number of sliding symbols for each area number can be acquired by expanding the stop control table. Yes.

  As described above, the stop control table created by referring to the table index and the table creation data corresponds to the area number, and the area corresponding to each area number is the stop reference position (in this embodiment, the perspective window 3). Sliding frame when an operation of the stop switches 8L, 8C, 8R is detected at a timing (a timing in which the number of steps from the reel reference position is included in the range of the number of steps of each region number). It is a table with each number set.

  Next, the procedure for creating the stop control table will be described. First, at the start of reel rotation, the top address of the table creation data corresponding to the internal winning state of the game is acquired. Specifically, the table index is first referred to, index data corresponding to the internal winning state is obtained, table creation data is identified based on the obtained index data, and all reels are identified from the identified table creation data. The address of the stop control table for each reel corresponding to the state of rotation is acquired, and the stop control table for each reel stored at the acquired address is expanded to generate a stop control table for all reels.

  Further, when any one reel stops or any two reels stop, the index data acquired at the start of reel rotation, that is, the top address of the table creation data corresponding to the internal winning state of the game The table creation data is identified based on the table creation data, and the stop control table address of the unreacted reel corresponding to the stopped reel and the area number of the stop position of the reel is obtained from the identified table creation data. The stop control table for each stored reel is expanded to create a stop control table for the unstopped reels.

  Next, when the main CPU 41a effectively detects any one of the stop switches 8L, 8C, and 8R corresponding to the rotating reel, the control when the display result is derived to the corresponding reel will be described. When one of the stop switches 8L, 8C, and 8R corresponding to the rotating reel is effectively detected, the stop operation position area is determined based on the number of steps from the reel reference position when the stop operation is detected. The number is specified, the stop control table of the reel where the stop operation is detected is referred, and the number of sliding symbols corresponding to the area number of the specified stop operation position is acquired. Then, control is performed to rotate and stop the reel by the number of acquired sliding frames. Specifically, from the number of steps from the reel reference position at the time when the stop operation is detected, the number of steps from the acquired number of sliding frames to the stop is calculated, and the reel is rotated and stopped by the calculated number of steps. Take control. As a result, the area corresponding to the area number that is the stop position ahead of the number of sliding frames from the area corresponding to the area number of the stop operation position where the stop operation is detected is the stop reference position (in this embodiment, the perspective window 3 It will stop in the lower symbol area).

  In the table index of this embodiment, only one address is stored as index data corresponding to one internal winning state in one gaming state, and further, one table creation data includes one reel. Only one address is stored as the address of the storage area of the stop control table corresponding to the stop status (and the stop position of the stopped reel). In other words, table creation data corresponding to one internal winning state in one gaming state and stop control tables corresponding to reel stop states (and stopped positions of stopped reels) are uniquely determined. The stop control table created with reference to is unique for one internal winning state in one gaming state and the reel stop status (and the stop position of the stopped reel). Therefore, when all of the gaming state, the internal winning state, and the reel stop status (and the stop position of the stopped reel) are the same, the reel is based on the same stop control table, that is, the same control pattern. The stop control is performed.

  Further, in this embodiment, a value of 0 to 4 is determined as the number of sliding frames, and the reel can be stopped by drawing a maximum of 4 symbols after detecting the stop operation. In other words, the stop position of the symbol can be designated from a range of a maximum of 5 frames including the stop operation position where the stop operation is detected. In addition, since it is necessary to move one frame to move the reel for one symbol, it is possible to stop the reel by pulling in a maximum of four symbols after detecting the stop operation. The symbol stop position can be designated from a range of up to five symbols including the operation position.

  In this embodiment, when any of the winning combinations is won, the winning combination is drawn on the winning line to the maximum in the range of 4 frames, and the winning combination is aligned on any winning line. Create a stop control table that defines the number of sliding frames to be pulled in to prevent reels from being stopped, and if none of the winning combinations are selected, slipping that does not match any winning combination on the winning line A stop control table with a defined number of frames is created and reel stop control is performed. As a result, when a stop operation is performed, if a winning combination can be stopped on any winning line in a drawing range of a maximum of 4 frames, control is performed to align and stop them. In this case, the winning combination is controlled so that the winning combination is stopped within a drawing range of a maximum of 4 frames.

  If the special role is elected while the special role has been carried over from before the previous game, or if the special role and the small role are elected at the same time when the special role is not carried over, the special role and the small role are won simultaneously. The number of sliding symbols is set so that the winning small role is drawn to the winning line within the range of 4 frames, and the winning small role is drawn to the winning line within the range of up to 4 frames. For stop operation positions that cannot be inserted, a stop control table in which the number of sliding symbols is determined so as to draw the selected special combination to the winning line in the range of 4 frames to the maximum is created, and reel stop control is performed. As a result, when a stop operation is performed, if it is possible to stop all the small roles that have been selected in the drawing range of up to 4 frames on the winning line and stop them, control is performed so that the winning combination is stopped. If you can't draw a small role that has been won in the drawing range of up to 4 frames on the line, if you can stop with a special role that has been won in the drawing range of up to 4 frames on the winning line, A control is performed to stop them in a uniform manner, and a winning combination that has not been won will be controlled to be stopped within a 4-frame pull-in range. That is, in such a case, priority is given to the control for aligning the small combination on the winning line over the special combination, and the special combination can be won only when the small combination cannot be drawn.

  In this embodiment, when a special role and a small role are simultaneously elected, the control for aligning the small role on the winning line is prioritized over the special role, and the special role is given only when the small role cannot be drawn. However, priority is given to the control of aligning the special role on the winning line over the small role, and it is possible to win the small role only when the special role cannot be drawn. It is good also as a structure.

  The special role and re-playing role are selected when the re-playing role is elected while the special role has been carried over from before the previous game, or when the special role and re-playing role are won at the same time without the special role being carried over. In the case of winning at the same time, when a stop operation is performed, control is performed so that the symbols of the re-gamer are aligned and stopped on the winning line within a drawing range of a maximum of 4 frames. In this case, the symbols constituting the re-playing combination are arranged within 5 symbols for each of the reels 2L, 2C, and 2R, that is, with an interval of 4 frames or less. Therefore, if a special combination and a replaying player are elected at the same time, the replaying game will always be awarded regardless of the operation timing of the stop switches 8L, 8C and 8R by the player. Will be. That is, in such a case, the control for aligning the re-games on the winning line has priority over the special game, and the re-games will always win.

  In this embodiment, after the rotation of the reels 2L, 2C, and 2R is started, the main CPU 41a continues to rotate the reels for which the stop operation has not been detected until the operation of the stop switches 8L, 8C, and 8R is detected. On the condition that the operation of the stop switches 8L, 8C, 8R is detected, control is performed to stop the display result on the corresponding reel. Even if the reel rotation temporarily stops due to the occurrence of a reel rotation error, the stop operation is still detected until the operation of the stop switches 8L, 8C, and 8R is detected after the reel rotation is restarted. Control is performed to stop the display result of the corresponding reels on the condition that the rotation of the reels that have not been continued is continued and the operation of the stop switches 8L, 8C, and 8R is detected.

  In this embodiment, control is performed to stop the display result on the corresponding reel on condition that the operation of the stop switches 8L, 8C, and 8R is detected. However, the rotation of the reel is started. When a predetermined automatic stop time has elapsed, even if the reel stop operation is not performed, it is assumed that the stop operation has been performed, and automatic stop control is performed to automatically stop each reel. May be. In this case, since the reels are stopped without the player's operation, it is preferable to derive a display result that does not constitute any combination even if any combination is won.

  In the present embodiment, the main CPU 41a sends a BET command, a credit command, an internal winning command, a reel rotation start command, a reel stop command, a winning determination command, a payout start command, a payout end command, a game state command to the effect control board 90. A plurality of types of commands including a standby command, an abort command, an error command, a return command, a setting start command, a confirmation start command, a confirmation end command, and an operation detection command.

  These commands are composed of 1-byte type data indicating the type of command and 1-byte extension data indicating the content of the command, and the sub CPU 91a can determine the type of command from the type data.

For example, the cap and the sealing pieces 230 to 232 can be mounted. May be closed with an adhesive, or the upper surface openings of the sealing pieces 230 to 232 may be closed with caps.

  Further, as shown in FIG. 6, the game control board 40 is attached to the back side of the upper case 202 by fastening four corners with four attachment screws 238. The game control board 40 is attached to the back surface side of the upper case 202 with the mounting surface 40a (mounting surface) on which electronic components or the like are mounted (mounted) facing the back surface of the upper case 202, and is attached. In FIG. 2, the back surface 40b of the mounting surface 40a is accommodated so as to be positioned above the lower ends of the side walls 202b to 202d.

(Sealing the substrate case)
Next, a sealing state between the lower case 201 and the upper case 202 will be described.

  First, as shown in FIG. 6, the game control board 40 is attached to the back side of the upper case 202 via the attachment screw 238. At this time, with the mounting surface 40 a of the game control board 40 facing the back surface of the upper case 202, the game control board 40 is fitted and positioned in the upper case 202, and mounting screws 238 are placed at the four corners of the game control board 40. Is attached to a screw hole (not shown) of the upper case 202.

  Thus, even if the upper case 202 is illegally opened, the upper case 202 is illegally opened by housing the game control board 40 so that the mounting surface 40a is covered on the back side of the upper case 202. Unless the game control board 40 is removed from 202, it becomes impossible to perform illegal acts on the electronic components such as the main CPU 41a and the ROM 41b mounted on the mounting surface 40a.

  Next, the back surface 40b of the game control board 40 attached to the back surface side of the upper case 202 is opposed to the upper surface of the bottom plate 201a of the lower case 201, and the upper case so that the side wall 202c of the upper case 202 protrudes from the short side 201c of the lower case 201. 202 is brought close to the lower case 201, and each engagement piece 220 of the upper case 202 is inserted from the open end of each engagement groove 250 of the lower case 201. At this time, the outer surface of the side wall 201b of the lower case 201 is covered by the side wall 202c of the upper case 202. In this state, the upper case 202 is slid in the longitudinal direction (toward the right side in FIG. 6) toward the right side.

  When each engagement piece 220 comes into contact with the end portion of each engagement groove 250 and the right end portion of the upper fixing piece 223 comes into contact with the restriction piece 208 and the sliding movement is restricted, on the short side on the left side, The locking pieces 203, 203 of the lower case 201 are inserted into the upper case insertion holes 222, 222. Thus, each engagement piece 220 is engaged with each engagement groove 250, the right end portion of the upper fixing piece 223 is locked to the restriction piece 208, and the locking pieces 203, 203 are the upper case insertion holes 222, 222. By being inserted into the inside, the position of the upper case 202 with respect to the lower case 201 is determined, and the lower case 201 and the upper case 202 are in a closed state (locked state) and can be sealed as described later. It will be in a state (refer to Drawing 9 and Drawing 10).

  As described above, in the substrate case 200 of this embodiment, when the upper case 202 is not slid along the bottom plate 201a of the lower case 201, the upper case 202 is locked or released from the locked state with respect to the lower case 201. In other words, the engagement of the upper case 202 from the lower case 201, that is, the lifting, is effectively restricted by the locking action.

  Further, in the aligned state, the mounting hole 234 of the preliminary sealing piece 232 is disposed at a position facing the screw hole 210, and the mounting hole 227 is disposed at a position facing the screw hole 209. The piece 223 is disposed at a position facing the lower fixing portion 207 (see FIG. 10A).

  Here, for example, when the game control board 40 is stored in the board case 200 and shipped to a game store or the like by a manufacturer or the like, the upper fixing piece 223 and the lower fixing part 207 which are special fixing parts are fixed ( And the sealing screw 226 attached to the attachment hole 227 is screwed into the screw hole 209, and then the sealing seal 225 is attached from the upper surface of the sealing plate 224 to the lower surface of the lower case 201, and the attached sealing seal 225 is attached. A U-shaped seal protective cover 228 made of a synthetic resin material is mounted so as to sandwich the upper case 202 and the lower case 201 so as to cover the surface, and is shipped after being in a special sealed state.

  Specifically, the upper fixing piece 223 and the lower fixing portion 207 are ultrasonically welded using a welding device (not shown). As shown in FIG. 10A, in a state where the lower fixing portion 207 is disposed on the lower surface side of the upper fixing piece 223, the flat lower surface of the upper fixing piece 223, and the flat lower surface of the lower fixing portion 207 Are in contact with each other. In this state, with the lower fixing portion 207 placed on the base of a welding apparatus (not shown), the upper fixing piece 223 is pressed from the upper surface by a tool such as a horn (not shown) to be ultrasonically vibrated. Accordingly, the flat lower surface of the upper fixing piece 223 and the flat lower surface of the lower fixing portion 207 which are in contact with each other are cured after being melted and deformed, so that the opposing surfaces are welded and integrated with each other. In addition, after welding, an instrument such as a horn of a welding apparatus for fixing the upper fixing piece 223 and the lower fixing portion 207 does not remain in the special fixing portion.

  Note that bubbles generated between the lower surface of the upper fixing piece 223 and the upper surface of the lower fixing portion 207 at the time of ultrasonic welding are accommodated in a concave groove formed on the upper surface of the lower fixing piece 213, thereby Even if the above pressure is not applied, the adhesion around the annular groove is effectively increased. Accordingly, the upper fixing piece 223 and the lower fixing portion 207 are difficult to peel off, and a tool or the like is provided between the lower surface of the upper fixing piece 223 and the upper surface of the lower fixing portion 207 from the side surfaces of the upper fixing piece 223 and the lower fixing portion 207. It becomes difficult to be inserted.

  As described above, the lower surface of the upper fixing piece 223 and the upper surface of the lower fixing portion 207 are melt-deformed and fixed (welded) to be integrated with each other. Since the lower surface of the upper fixing piece 223 and the upper surface of the lower fixing portion 207 are fixed in this manner, the sliding movement of the upper case 202 with respect to the lower case 201 is restricted. The stop state cannot be released. That is, a special sealing state is formed in which the upper case 202 cannot be opened unless the fixed state between the lower surface of the upper fixing piece 223 and the upper surface of the lower fixing portion 207 is released.

  Here, for example, when the upper fixing piece 223 and the lower fixing portion 207 are peeled off by forcibly sliding the upper case 202 in the unlocking direction with respect to the lower case 201, the opposing surfaces melt. Therefore, the upper case 202 is opened (opened) because scratches and deformation marks remain on both the upper fixing piece 223 and the lower fixing portion 207, that is, both the lower case 201 and the upper case 202. It can be surely discovered that there is a possibility.

  Further, as shown in FIG. 10A, the side portion between the opposing surfaces of the upper fixing piece 223 and the lower fixing portion 207 is covered with the wall portion and the regulating piece 208, so that the upper fixing piece 223 and the lower fixing portion 207 are covered with each other. Since it becomes difficult to insert a cutter or the like from the side between the opposing surfaces of the fixing portion 207, it is difficult to peel off.

  Further, after the closure screw 226 attached to the attachment hole 227 is screwed into the screw hole 209, the seal screw 226 and the recess 227a are attached by sticking the seal seal 225 so as to straddle the lower case 201 from the upper surface of the seal plate 224. The top opening is concealed by a seal seal 225. The seal seal 225 is specially printed, and is a high-adhesive special seal that is broken when peeled once it is attached to the surface to be attached or a part of the adhesive part remains on the surface to be attached. Yes. That is, not only is it difficult to specify the position of the upper surface opening of the closing screw 226 and the recess 227a, but it becomes impossible to approach the closing screw 226, so that the sealing seal 225 must be peeled or broken to remove the closing screw 226. This ensures that traces remain.

  Further, as shown in FIG. 6, the seal seal 225 is provided with an IC tag 225a in which seal identification information (seal ID) that can identify each seal seal is recorded. Since the seal identification information and the board identification information (board ID) that can identify each game control board 40 can be managed in association with each other, the seal seal 225 is peeled off and an illegal seal sticker is attached. However, by reading the seal identification information recorded on the IC tag with the reading device and collating it with the seal identification information registered in the database or the like, it is possible to identify the possibility of fraudulent acts. It has become.

  Further, the IC tag 225a is provided at a position straddling the separation portion between the lower case 201 and the upper case 202 when the sealing seal 225 is stuck, thereby illegally opening the upper case 202 with respect to the lower case 201. Since the IC tag 225a is sometimes easily broken, it is prevented that the IC tag 225a is taken out from the seal sticker 225 and attached to an illegally produced seal sticker.

  In addition, as shown in FIG. 6, it is difficult to touch the seal seal 225 by attaching the seal protection cover 228 to the outer surface of the seal seal 225 adhered in this way to cover the entire surface. The seal protective cover 228 has an engagement recess 228a that can be engaged with a plurality of engagement portions (not shown) formed in the upper case 202 and the lower case 201 on the inner surface. It cannot be removed easily. In this way, it takes time to open the upper case 202 illegally, thereby making it extremely difficult to perform an illegal act.

  Further, the upper case 202 has a structure that cannot be detached from the lower case 201 unless the upper case 202 is slid in the unlocking direction with respect to the lower case 201 from the aligned state. That is, a slide movement guide means is provided that slides and guides in a direction substantially perpendicular to the direction in which the upper case 202 is detached from the lower case 201, and is locked in a state in which the slide movement guide means guides the slide movement. Since the upper fixing piece 223 and the lower fixing portion 207 cannot be separated so as to be separated toward each other in the locked state, the upper fixing piece 223 and the lower fixing portion 207 can be separated from each other. It is extremely difficult to peel off.

  Further, even when two substrate cases of the same type as the substrate case 200 are obtained as in the prior art, both of the lower case 201 and the upper case 202 remain scratched when the upper case 202 is opened. Since the case 201 and the upper case 202 cannot be obtained, it is extremely difficult to illegally configure the new substrate case 200.

  As described above, the upper fixing piece 223 and the lower fixing portion 207 are welded (fixed) to each other, so that the sliding movement of the upper case 202 with respect to the lower case 201 is restricted. That is, in the state where the locking pieces 203, 203 formed on one short side of the lower case 201 are locked to the insertion holes 222, 222 of the upper case 202, the upper fixing piece 223 and the lower fixing side of the other short side are fixed. By adhering to the portion 207, a special sealing state in which the upper surface of the lower case 201 is closed by the upper case 202 is configured. This special sealing state cannot be released unless both the upper fixed piece 223 of the upper case 202 and the fixed portion of the lower fixed portion 207 of the lower case 201 are cut (broken), so the upper case 202 is opened. In such a case, the trace, that is, the trace that a part of the board case 200 is destroyed remains without fail, and this may cause some illegal acts on the game control board 40 housed in the board case 200. It becomes possible to discover that there is.

  In this embodiment, when the lower case 201 and the upper case 202 are aligned at the closed position, the upper surface of the upper fixing piece 223 and the lower surface of the lower fixing portion 207 are in contact with each other. The upper surface of the upper fixing piece 223 and the lower surface of the lower fixing portion 207 may be spaced apart from each other as long as they can be welded to each other. In this case, for example, spot welding or the like in which a boss (not shown) formed at the tip of the horn is pushed down to the upper upper fixing piece 223 while the lower lower fixing portion 207 is dissolved can be applied.

  Next, the configuration of the case support device 300 will be described with reference to FIGS. 6 and 11 to 16.

(Case support device)
As shown in FIG. 6, the case support device 300 is attached to the upper portion of the inner surface of the back plate 1 c of the housing 1 a, the locking member 303 attached to the right side of the fixed base 301, and the fixed base 301. The movable base 302 is movably supported. The movable base 302 has a substrate case 200 attached to the front side, and is supported so as to be rotatable around a rotation axis that faces the fixed base 301 in the vertical direction.

  Then, by attaching the substrate case 200 to the front side of the movable base 302, the substrate case 200 is arranged in the first rotation restricting position A (the rear surface 40b side of the game control substrate 40 is opposed to the back plate 1c and cannot be visually recognized. The inner surface of the back plate 1c so as to be rotatable between the first position) and the second rotation restricting position B (second position) at which the back surface 40b side of the game control board 40 is visible. Since it is supported at the top (see FIG. 20A), the mounting surface 40a and the back surface 40b of the game control board 40 accommodated in the board case 200 are transparent even when the board case 200 is attached to the back plate 1c. It can be visually recognized through the flexible substrate case 200 and the movable base 302.

  As shown in FIG. 11, the movable base 302 is made of a transparent thermoplastic synthetic resin, and has a substantially rectangular bottom plate 310a, and a pair of side walls erected forward on the upper and lower long sides of the bottom plate 310a. 310b and 310b extend in the longitudinal direction, short side walls 310c and 310c are provided from both ends of the left short side in the longitudinal direction from the ends of the side walls 310b and 310b, and the right short side has a short side. The side wall 310d is extended in the longitudinal direction.

  An elastic locking claw 311 capable of locking a predetermined portion of the upper case 202 in the substrate case 200 attached to the front side of the bottom plate 310a is formed inward at the right end of the upper side wall 310b. 200 can be locked.

  A board-side connector 620c (see FIG. 9) of the game control board 40, a cable-side connector 610c connected to the board-side connector 620c, and a protective member 660 for protecting the cable 600c are attached to the left end of the lower side wall 310b. A mounting slit 312 is formed. The attachment slit 312 is formed by bulging a part of the side wall 310b, and can be inserted through the attachment piece 660a of the protection member 660. Further, a locking hole 312a is formed on the outer surface of the mounting slit 312 so that the outward elastic locking claw 660b formed in the mounting piece 660a is locked. It can be regulated.

  In this way, the attachment piece 660a is inserted into the attachment slit 312 and the elastic engagement claw 660b is engaged with the engagement hole 312a, so that the guard piece 660c and the guard side piece formed to be bent with respect to the attachment piece 660a. The periphery of the board-side connector 620c, the cable-side connector 610c connected to the board-side connector 620c, and the cable 600c is covered and protected by 660d.

  Attachment in which attachment holes 316a and 316b to which the one-way screws 240a and 240b inserted into the attachment sealing piece 230 and the preliminary attachment sealing piece 231 of the substrate case 200 are attached are formed in the vicinity of the right short side portion of the bottom plate 310a. A pedestal mounting hole 317 for mounting the pedestal 315 is formed. The mounting base 315 is mounted by fitting into the base mounting hole 317 from the back side of the bottom plate 310a. At the time of mounting, as shown in FIG. 19 (a), the mounting holes 316a and 316b protrude forward from the front surface of the bottom plate 310a, and the mounting holes 235 and 235 of the mounting sealing piece 230 and the preliminary mounting sealing piece 231 are provided. 235 is arranged to face the 235.

  As described above, the mounting base 315 is detachably mounted on the movable base 302, so that, for example, the mounting sealing piece 230 and the preliminary mounting sealing piece 231 are cut from the substrate case 200 and movable as described later. When left on the base 302 side or the like, only the mounting base 315 can be replaced with a new one.

  An insertion hole through which the locking pins 303a and 303a of the locking member 303 for locking the free end of the movable base 302 to the front side of the back plate 1c can be inserted in the short side portion on the right side of the movable base 302. 318 and 318 are formed, and in the vicinity of the insertion holes 318 and 318, locking hooks 319 and 319 that can be locked to the tips of the locking pins 303 a and 303 a are rotated around an axis that faces in the front-rear direction. It is mounted movably.

  From both sides in the longitudinal direction of the short side on the left side of the movable base 302, a plate-like shape in which a shaft support groove 320 having a substantially U shape for receiving a rotation shaft 333 formed on the fixed base 301 described later is formed. The shaft support plates 321 and 321 are projected outward in a direction orthogonal to the short side portion. The shaft support groove 320 extends rearward from the front end sides of the shaft support plates 321 and 321, and the rotation shaft 333 can be attached to and removed from the opening portion on the front side.

  A covering portion 322 that covers a base mounting screw 335 for mounting a fixed base 301 (to be described later) to the back plate 1c is formed at the central position in the longitudinal direction of the short side portion on the left side of the movable base 302. The covering portion 322 is parallel to the vertical piece 322b erected vertically from the short side of the bottom plate 310a toward the front, and the bottom plate 310a bent outward from the tip of the vertical piece 322b. A bent piece 322a, side pieces 322c and 322c that cover the sides of the bent piece 322a and the vertical piece 322b, and an outer piece 322d that inclines outward from the tip of the bent piece 322a (FIG. 16). (See (b)). Further, as shown in FIG. 16B, the bent piece 322a has such a length that it can cover the upper portion of the base mounting screw 335 in a state where the pivot groove 320 is pivotally supported on the rotation shaft 333 of the fixed base 301. Have.

  The upper and lower side pieces 322c and the shaft support plate 321 are arranged with a predetermined distance therebetween, and an insertion portion through which the plate-like piece 221 of the upper case 202 can be inserted between the side pieces 322c and the shaft support plate 321. 324 and 324 are formed. Since the insertion portions 324 and 324 are formed to have a vertical width slightly longer than the vertical width of the plate-like pieces 221, 221, the substrate case 200 is attached to the front side of the movable base 302 as will be described later. In this state, the upper and lower side portions of the plate-like pieces 221 and 221 inserted through the insertion portions 324 and 324 are guided by the side piece 322c and the shaft support plate 321. Further, the vertical piece 322b contacts the side wall 202c of the upper case 202 and determines the position of the substrate case 200 in the left-right direction with respect to the movable base 302.

  At the distal end portions of the insertion portions 324 and 324, band plate-like locking plates 323 and 323 that lock the front side of the distal end portions of the plate-like pieces 221 and 221 inserted through the insertion portions 324 and 324 are pivotally supported. It is constructed between the plate 321 and the side piece 322c. That is, the upper and lower shaft support plates 321 and the side pieces 322c are connected by the locking plates 323 and 323, respectively. Further, since the locking plates 323 and 323 are disposed outside the shaft support grooves 320 and 320, they do not interfere when the rotating shafts 333 and 333 are attached to and detached from the shaft support grooves 320 and 320.

  Next, as shown in FIGS. 12 and 13, the fixed base 301 has a strip-shaped attachment piece 330 a that is attached to the inner surface of the back plate 1 c and that faces in the vertical direction, and an upper and lower end portion of the attachment piece 330 a. A main body portion made of a plate-shaped metal material composed of a pair of upper and lower shaft pieces 330b, 330b bent toward the front, and a protective piece 330c bent forward from the left side of the mounting piece 330a; From the opposing surfaces of the pieces 330b and 330b, cylindrical rotation shafts 333 and 333 are provided that protrude inward so that their respective axes are located on the same line, and that are in the vertical direction. Yes.

  The pair of upper and lower rotating shafts 333 and 333 are arranged in parallel to the mounting piece 330a at a position in front of the mounting piece 330a so that the tip portions thereof are separated from each other by a predetermined distance. In addition, mounting holes 331 and 331 for base mounting screws 335 and 335 for mounting the fixed base 301 to the back plate 1c are formed between the tips of the rotating shafts 333 and 333 in the mounting piece 330a. In addition, positioning holes 332 and 332 are formed between the mounting holes 331 and 331 so that positioning protrusions 336e formed on the back surface of a cover member 336, which will be described later, are fitted.

  The base mounting screw 335 is formed with a screw portion 335a having a male screw portion formed on the outer periphery, and an operation groove 335c (operation portion) that can be operated by a driver on the surface of the screw portion 335a. And a so-called general screw that can be attached and detached by rotating the forward and reverse directions by fitting the tip of the driver into the operation groove 335c.

  The cover member 336 includes a bottomed cylindrical accommodating portion 336a, 336a that can accommodate the head portion 335b of the base mounting screw 335, and a connecting portion 336c that couples the pair of accommodating portions 336a, 336a. . A mounting hole 336b to which a base mounting screw 335 is attached is formed on the bottom surface of each housing portion 336a, and a cover cap 337 capable of closing the opening of the housing portion 336a is formed on the peripheral surface of each housing portion 336a. Locking portions 336d and 336d to which the formed elastic locking claws 337a and 337a are locked are formed.

  As shown in FIG. 12, the fixed base 301 configured as described above has two base mounting screws 335 and 335 inserted into the mounting holes 336 b and 336 b of the cover member 336, respectively, and mounting holes 331 and 331 of the fixed base 301. As shown in FIG. 13, by screwing into a screw hole 338a of a nut 338 embedded in the back plate 1c, it can be attached and fixed to the inner surface of the back plate 1c.

  As shown in FIGS. 13A and 13B, the base mounting screws 335 and 335 attached to the fixed base 301 are orthogonal to the axis P1 at which their axes P2 and P2 connect the rotation axes 333 and 333, respectively. And is disposed between the tip ends of the rotating shafts 333 and 333 provided in a pair of upper and lower sides. Further, the longitudinal width dimension L2 of the cover member 336 is smaller (L1> L2) than the separation width L1 of the distal end portions of the rotating shafts 333 and 333, so that when the fixed base 301 is attached to the back plate 1c, The base mounting screw 335 and the cover member 336 do not interfere with the rotation shafts 333 and 333.

  That is, the base mounting screws 335 and 335 are arranged along the axis P1 of the pair of upper and lower rotating shafts 333 and 333, so that the fixed base 301 is attached to the back plate 1c at a position closer to the rotating shafts 333 and 333. Since it is attached, the support strength of the rotating shafts 333 and 333 can be increased. On the other hand, the base mounting screw 335 and the cover member 336 are disposed between the pair of upper and lower rotating shafts 333 and 333, thereby rotating the rotating shaft 333. , 333 can be easily attached and detached without interference.

  Further, the head 335b of the base mounting screw 335 that is exposed to the outside when the fixed base 301 is attached to the back plate 1c is accommodated in the accommodating portion 336a of the cover member 336, and further, the accommodating portion 336a is accommodated by the cover cap 337. As shown in FIG. 13B, the base mounting screw 335 is completely covered around the head 335b exposed to the outside in a state of being attached to the back plate 1c. It becomes difficult to insert the driver between the operation groove 335c or the head 335b and the back plate 1c. The cover member 336 is attached to the base mounting screw 335 and cannot be removed unless the base mounting screw 335 is removed. Therefore, the cover member 336 need not be separately attached with a mounting screw, and the covering state can be easily released. Absent. Further, since the protective piece 330c has a longer front-rear width than the cover member 336, the outer side of the cover member 336 is reliably covered.

(Mounting the movable base to the fixed base)
Next, a method for attaching the movable base 302 to the fixed base 301 will be described with reference to FIGS.

  First, as shown in FIG. 14, the fixed base 301 is attached to the upper left side of the inner surface of the back plate 1 c with the base mounting screws 335 and 335 as described above, and the locking member 303 is placed on the right side of the fixed base 301. Install. In a state where the fixed base 301 is attached, the axis P1 of the rotation shafts 333 and 333 is directed in the vertical direction.

  The locking member 303 is not specifically shown in detail, but a strip-shaped attachment piece 303b whose both ends are attached to the back plate 1c by attachment screws 339 and 339 of the same type as the base attachment screw 335, and an attachment piece 303b. The locking pins 303a and 303a are erected from the upper and lower positions toward the front. And it attaches to the backplate 1c so that locking pin 303a, 303a may be arrange | positioned corresponding to the insertion hole 318,318 of the movable base 302 pivotally supported by the fixed base 301 so that it may mention later.

  When the movable base 302 is attached to the fixed base 301, first, as shown in FIG. 14, the left and right end portions of the movable base 302 are oriented in the longitudinal direction so as to be orthogonal to the back plate 1c with the front-rear direction. As a result, since the open portions of the shaft support grooves 320 and 320 face the rotation shafts 333 and 333, the movable base 302 is brought close to the fixed base 301 in this posture, and the shaft support grooves 320 and 320 are moved to the rotation shaft 333. After being inserted into 333, the front side of the movable base 302 is pushed toward the back plate 1 c around the rotation shafts 333 and 333.

  When the movable base 302 is disposed in the lateral orientation in which the rear surface faces the inner surface of the back plate 1c, that is, in the first rotation restricting position A, the locking pins 303a and 303a of the locking member 303 are moved to the movable base 302. The locking hooks 319 and 319 are rotated to the tips of the locking pins 303a and 303a that are inserted through the insertion holes 318 and 318, and the tips of the locking pins 303a and 303a protrude forward from the insertion holes 318 and 318, respectively. Lock. Accordingly, the left end portion of the movable base 302 is pivotally supported by the rotation shafts 333 and 333, and the right end portion is locked by the locking pins 303a and 303a, whereby the movable base 302 is detached from the back plate 1c. And the rotation around the rotation shafts 333 and 333 is restricted, and temporarily fixed at the first rotation restriction position A substantially parallel to the back plate 1c.

  15 and 16 show details of a shaft support portion that rotatably supports the movable base 302 with respect to the fixed base 301. FIG. As described above, when the pivot shafts 333 and 333 of the fixed base 301 are pivotally supported by the pivot support grooves 320 and 320 of the movable base 302 and the movable base 302 is disposed at the first rotation restriction position A, the pivot support groove 320 is provided. , 320 open frontward in the front-rear direction, but the back plate 1c is close to the rear surface of the movable base 302, so that the rearward movement of the shaft support grooves 320, 320 relative to the rotating shafts 333, 333 is restricted. Therefore, the shaft support grooves 320 and 320 are not detached from the rotation shafts 333 and 333.

  In other words, if the movable base 302 is only pivotally supported with respect to the fixed base 301, the movable base 302 is placed in the attachment / detachment position C (about 63 from the first rotation restriction position A) in the vertical orientation. 20 (a)), the movement of the movable base 302 with respect to the fixed base 301 is not restricted so that it can be attached to and detached from the fixed base 301. It becomes. As shown in FIG. 16A, the rotation shaft 333 and the locking plate 323 are arranged apart from each other in the front-rear direction, and there is a gap through which the plate-like piece 221 of the upper case 202 can be inserted. It is formed.

  Further, the front surface side of the base mounting screw 335 for attaching the fixed base 301 to the back plate 1c is covered with the covering portion 322 of the movable base 302, and the left outer side is covered with the protective piece 330c, particularly in FIG. As shown, only a slight gap is formed between the protective piece 330c and the tip of the outer piece 322d. Therefore, not only is it difficult to contact the driver or finger with the base mounting screw 335, but also the driver cannot be placed on the extension line of the axis P2 of the base mounting screw 335.

(Attaching the substrate case to the movable base)
Next, a method for attaching the substrate case 200 to the movable base 302 rotatably supported by the fixed base 301 will be described with reference to FIGS.

  As shown in FIG. 17, in order to attach the substrate case 200 in the sealed state as described above to the movable base 302 temporarily fixed at the first rotation restricting position A, the back side of the lower case 201 is attached. A pair of plate-like pieces 221 and 221 provided on the left short side of the upper case 202 by being slid to the left in a state of being arranged so as to face the front surface of the movable base 302 are indicated by arrows in the upper diagram of FIG. As shown by the thick arrows in the lower diagram of FIG. 17, after being inserted into the gap formed between the rotating shafts 333 and 333 and the locking plates 323 and 323 (see FIG. 16A). Then, the right short side of the substrate case 200 is pushed toward the movable base 302.

  At this time, the tips of the plate-like pieces 221 and 221 are locked to the locking plates 323 and 323 (see FIG. 19B), and the upper side of the upper case 202 is elastically locked to the movable base 302. Locked to the claw 311. The substrate case 200 is covered with the side walls 310b, 310c, and 310d of the movable base 302, so that the sliding movement of the movable base 302 on the bottom plate 310a is restricted, so that the separation from the movable base 302 is restricted. .

  However, in this temporarily fixed state, the substrate case 200 can be easily removed from the movable base 302 by releasing the locked state of the upper case 202 by the elastic locking claw 311.

  Further, in the temporarily fixed state, the mounting sealing piece 230 and the preliminary mounting sealing piece 231 in the upper case 202 are arranged to face the mounting base 315, and the mounting holes of the mounting sealing piece 230 and the preliminary mounting sealing piece 231 are provided. 235 and 235 match the mounting holes 316 a and 316 b of the mounting base 315. Here, as shown in FIG. 19A, when the one-way screw 240a housed in the mounting sealing piece 230 is screwed into the mounting hole 316a by a screwdriver, the board case 200 cannot be detached from the movable base 302. Attached to.

  That is, once the one-way screw 240a is attached to the attachment hole 316a, the one-way screw 240a cannot be rotated reversely even if a tool such as a screwdriver is inserted into the operation groove, that is, cannot be removed from the attachment hole 316a again. Therefore, the substrate case 200 is attached so that it cannot be removed from the movable base 302 unless a predetermined portion (for example, the cut piece 233 of the attachment sealing piece 230) of the substrate case 200 or the movable base 302 is cut (destroyed). Installed in a state.

  Further, when removing the board case 200 from the movable base 302 for inspection of the game control board 40, it is necessary not only to cut the cutting piece 233 of the mounting sealing piece 230 but also a one-way screw screwed into the mounting hole 316a. 240a and the mounting sealing piece 230 cut from the substrate case 200 cannot be removed from the mounting base 315 and remain held by the movable base 302. Therefore, the one-way screw 240a is attached to the mounting sealing piece 230, and the same Thus, it cannot be attached to the movable base 302. That is, once the mounting state of the substrate case 200 with respect to the movable base 302 is released, the spare one-way screw 240b is attached to the spare mounting sealing piece 231 different from the mounting sealing piece 230 used for the mounting once. It attaches to the attachment hole 316b.

  In this attached state, as shown in FIG. 19B, the plate-like pieces 221 and 221 are inserted into gaps formed between the rotating shafts 333 and 333 and the locking plates 323 and 323. Thus, the detachment of the rotation shafts 333 and 333 from the shaft support grooves 320 and 320 is restricted by the plate-like pieces 221 and 221 of the substrate case 200 attached to the movable base 302. As a result, even if the movable base 302 is rotated and disposed at the above-described attachment / detachment position C, the pivotal support state of the movable base 302 with respect to the fixed base 301 cannot be released.

  Unless the substrate case 200 is removed from the movable base 302, the plate-like pieces 221 and 221 inserted into the gap formed between the rotating shafts 333 and 333 and the locking plates 323 and 323 are taken out from the gap. In other words, since it is not possible to release the restriction of detachment of the shaft support grooves 320, 320 from the rotating shafts 333, 333, not only the substrate case 200 is removed from the movable base 302 but also the movable base 302 with respect to the fixed base 301 The movable base 302 cannot be detached from the fixed base 301 no matter what rotational position it is placed.

  Further, the rotation shafts 333 and 333 are covered with plate-like pieces 221 and 221 inserted into gaps formed between the rotation shafts 333 and 333 and the locking plates 323 and 323. Specifically, the locking plates 323 and 323 have a slightly smaller width than the separation width between the shaft support plate 321 and the side piece 322c, so that the rotation shafts 333 and 333 and the locking plate 323 are arranged. , 323, the movable base 302 is separated from the fixed base 301 by cutting the rotary shafts 333 and 333 in order to cover the longitudinal directions of the rotary shafts 333 and 333. Unauthorized actions such as removal are prevented.

  Further, in this mounted state, as shown in FIGS. 20 and 21, no matter what rotational position the movable base 302 is placed with respect to the fixed base 301, a base mounting screw 335 for mounting the fixed base 301 to the back plate 1c. Is covered with the covering portion 322 of the movable base 302, that is, the covering portion 322 is disposed opposite to the front surface side of the base mounting screw 335, and the left outer side is covered with the protective piece 330 c. Even if a driver or a finger is brought into contact with 335, not only is the contact difficult, but the driver cannot be placed on an extension line of the axis P2 of the base mounting screw 335.

  More specifically, as shown in FIG. 20 (a), the movable base 302 is disposed with respect to the fixed base 301, and the first rotation restricting position A (first position) where the movable base 302 is disposed along the back plate 1c. 1 position), and a rotation restriction position B (second position) where rotation is restricted when the right side of the movable base 302 is rotated about 83 degrees around the rotation shaft 333. Even if it is arranged at an arbitrary position within the rotatable range (θ≈0 to 83 degrees), a slight gap is formed between the protective piece 330c and the tip of the outer piece 322d (see FIG. 21). ).

  However, as shown in FIGS. 21A to 21C, a covering portion 322 is always disposed on the axis P <b> 2 of the base mounting screw 335, and the head 335 b of the base mounting screw 335 to the covering portion 322. Is about 3 cm at the maximum, so that the driver's tip can be inserted through the gap between the protective piece 330c and the tip of the outer piece 322d, but the driver's tip is inserted into the operation groove 335c, and the driver Even if the driver is arranged in a vertical posture along the axis P2, the driver interferes with the covering portion 322, that is, the removal operation is prevented, which is extremely difficult.

  In particular, the base mounting screw 335 is disposed immediately below the axis P1 of the rotating shaft 333, and the covering portion 322 is disposed on the axis P2 of the base mounting screw 335, so that the base mounting screw 335 is movable around the rotating shaft 333. Even when the base 302 is rotated, the covering portion 322 always rotates around the axis passing through the axis P2 of the base mounting screw 335, so that the positional relationship between the covering portion 322 and the base mounting screw 335 (separation distance). ) Does not change greatly, so that a driver or the like is disposed between the head 335b of the base mounting screw 335 and the covering portion 322 when the movable base 302 is disposed at any position within the rotatable range. It is difficult to do.

  Therefore, in the mounted state, the base mounting screw 335 cannot be removed from the back plate 1c unless the substrate case 200 is removed from the movable base 302. Therefore, the substrate case 200 can be detached from the movable base 302 or moved from the fixed base 301. Not only can the base 302 be removed, but also the fixed base 301 cannot be removed from the back plate 1c, so that it is possible to prevent the substrate case 200 from being removed from the back plate 1c together with the case support device 300.

  As shown in FIGS. 20 and 22, the board case 200 attached to the case support device 300 attached to the back plate 1c in this way has the electronic component mounting surface 40a of the game control board 40 facing the front side. A first rotation restricting position A (first position) where the back surface 40b faces the inner surface of the back plate 1c and cannot be seen from the front side of the housing 1a, and the mounting surface 40a is the left side plate of the housing 1a. A rotatable range (about 83) between the second rotation restriction position B (second position) where the back surface 40b side of the game control board 40 is opposed to the inner surface and is visible from the front surface side of the housing 1a. It is supported so as to be able to rotate within degrees.

  Therefore, when the board case 200 is positioned at the first rotation restricting position A, the mounting surface 40a of the game control board 40 faces the front side, so that the board case 200 does not have to be removed from the movable base 302. The mounting surface 40a can be viewed through the transparent upper case 202 from the front side of the housing 1a.

  Further, when the substrate case 200 is positioned in the vicinity of the second rotation restricting position B, the back surface 40b of the game control substrate 40 is separated from the back plate 1c and faces the right side. Even if it is not removed from 302, it is possible to visually recognize the back surface 40b from the front side of the housing 1a through the transparent lower case 201 and the transparent movable base 302. Therefore, even when the board case 200 is attached to the housing 1a, there is a trace that the mounting surface 40a and the back surface 40b of the game control board 40 accommodated therein are tampered with by simply rotating the board case 200. It can be easily confirmed visually whether or not there is.

  As shown in the upper diagram of FIG. 22, the substrate case 200 is normally disposed at the first rotation restricting position A. In this state, cable-side connectors of various cables are connected to the board-side connectors arranged to face the connector openings 236a to 236g formed in the upper case 202.

  Out of the connector openings 236a to 236g formed in the upper case 202, the connector openings 236a to 236c that the board side connectors 620a to 620c face are as shown in FIG. Is also provided on the left region, that is, on the side where the rotation shafts 333 and 333 are disposed. Of the board-side connectors 620a to 620c facing the connector openings 236a to 236c, the connection part between the cable-side connector 610c and the board-side connector 620c, one end of which is connected to the power supply board 101, is covered by the protective member 660 described above. In addition, the connection portion between the cable-side connector 610b and the board-side connector 620b, one end of which is connected to the start switch 7, is covered by the connector restricting member 650 described above, and in particular, the cable-side connector 610b covered by the connector restricting member 650. Is restricted from being removed from the board-side connector 620b.

  As described above, the cables 600a to 600c connected to the board-side connectors 620a to 620c provided in the region on the left side of the central position in the left-right direction of the upper case 202 are wired together on the inner surface of the left plate. The cable side connectors 610a to 610c provided on the cables 600a to 600c can rotate the board case 200 to the second rotation restricting position B without being removed from the board side connectors 620a to 620c. It has become. In addition, if the cable-side connector connected to the board-side connector provided in the region on the right side of the center position in the left-right direction of the upper case 202 is not removed from the board-side connector, the board case 200 is rotated in the second direction. It can be rotated to the restriction position B.

  In other words, the board-side connectors 620a to 620c arranged in the left region near the rotation shaft 333 have a movement distance when the substrate case 200 is rotated around the rotation shaft 333 so that the movement distance is far from the rotation shaft 333. Therefore, the surplus length of the connected cables 600a to 600c is shorter than that of the cable connected to the board-side connector arranged in the right region far from the rotation shaft 333. I'll do it.

  Therefore, if the board-side connectors 620a to 620c and the like that are covered by the protective member 660 and the connector restricting member 650 and are troublesome to remove are arranged in the left region near the rotation shaft 333, the board case 200 is rotated. Since it is not necessary to sequentially remove the cable-side connectors 610a to 610c from the board-side connectors 620a to 620c each time it is moved, the check operation of the game control board 40 is not complicated and the cables are connected to the board-side connectors 620a to 620a. When the substrate case 200 can be rotated without being removed from the 620c, the cables 600a to 600c can be shortened as much as possible.

  In this embodiment, the board-side connectors other than the board-side connectors 620a to 620c and the connector openings 236a to 236g corresponding to these board-side connectors are also arranged in the right region far from the rotation shaft 333 on the mounting surface 40a. However, for example, as shown in FIG. 25, it is preferable to provide all the board-side connectors provided on the mounting surface 40a and connector openings 236a to 236g corresponding to the respective board-side connectors in the left region of the mounting surface 40a. .

  Further, in this embodiment, all the board-side connectors including the board-side connectors 620a to 620c and the connector openings 236a to 236g corresponding to the board-side connectors are arranged along the long side of the mounting surface 40a. For example, as shown in FIG. 25, at least a part of all board-side connectors and connector openings 236a to 236g corresponding to each board-side connector (here, board-side connectors and connector openings other than board-side connectors 620a to 620c) 236d to 236g) are preferably disposed along the left short side close to the rotation shaft 333. That is, if the board side connectors and the connector openings 236d to 236g are arranged along the rotation shaft 333, the movement distances of the board side connectors are all the same, so that these cables can be shortened as much as possible.

  Although not particularly illustrated, the board-side connectors 620a to 620c that are covered by at least the protective member 660 and the connector restricting member 650 and are troublesome to remove are disposed along the left short side near the rotation shaft 333. Is preferred. That is, if the board side connectors 620a to 620c are arranged along the rotation shaft 333, the movement distances of the board side connectors 620a to 620c are all the same, so that the cables 600a to 600c can be shortened as much as possible.

  As described above, in the slot machine 1 according to the first embodiment of the present invention, the substrate case 200 is moved from the first rotation restricting position A to the second position even when the substrate case 200 is attached to the back plate 1c. Since the back surface 40b side of the game control board 40 can be visually recognized by rotating to the rotation restriction position B, it is possible to easily check whether or not the game control board 40 has been tampered with. it can. Further, when the movable base 302 is detached from the fixed base 301 or the substrate case 200 is detached from the movable base 302 in the assembled state in which the substrate case 200 is attached to the movable base 302, a cut piece 233 or a plate-like shape is obtained. Not only the traces are left by cutting the piece 221 and the like, but also when the base mounting screw 335 is removed and the fixed base 301 is removed from the back plate 1c, that is, the board case 200 is cut to be removed from the movable base 302. Since the trace remains even when the piece 233 is cut or the covering portion 322 or the cover member 336 of the movable base 302 is destroyed, the board case 200 is removed from the back plate 1c, and the board containing the illegal game control board 40 Found that there was a possibility of fraudulent actions such as turning back to Case 200 Rukoto can.

  In other words, the attachment of the substrate case 200 to the movable base 302, the attachment of the fixed base 301 to the movable base 302, and the attachment of the fixed base 301 to the back plate 1c destroy the attachment-related parts related to those attachments (cutting or If it is performed by the attachment means that cannot release each attachment state unless it includes (such as peeling), the trace remains reliably when each attachment state is released, and this causes illegal acts. It can be surely discovered that there was a possibility.

  In particular, in this embodiment, the front door 1b is pivotally supported on the left side of the housing 1a so that the substrate case 200 is also the same as the front door 1b when the front door 1b is opened. Since it rotates about the left side, when the back surface 40b of the substrate case 200 is visually recognized, the back surface 40b opens to the right without the front door 1b, and therefore the front door 1b becomes an obstacle when checking. There is no.

  Further, in a state where the substrate case 200 is located within the rotatable range between the first rotation restricting position A and the second rotation restricting position B, the covering portion 322 as the operation blocking portion is always provided. Since the operation groove 335c is disposed so as not to be operated, the fixing base 301 can not be removed from the back plate 1c without using a special mounting member such as a one-way screw, and the covering portion 322 can be removed. Is provided on the movable base 302 that is integrally assembled with the fixed base 301, so that it is not easily removed in the assembled state. In the present embodiment, the covering portion 322 as the operation blocking portion is provided on the movable base 302, but may be provided on the substrate case 200. Further, since the base mounting screw 335 is mounted in a state covered with the cover member 366, a tool such as a driver cannot be easily accessed.

  Further, since the movable base 302 is configured to be attached to and detached from the fixed base 301 from the attachment / detachment position C, the fixed base 301 can be easily attached and detached with the base attachment screw 335, and a one-way screw. By attaching the substrate case 200 to the movable base 302 by 240 a, the plate-like piece 221 provided in the attached substrate case 200 restricts the detachment of the rotation shaft 333 from the shaft support groove 320, and the fixed base 301. Since the cover 322 provided on the movable base 302 that can no longer be removed from the base can not always release the mounting state with the base mounting screw 335 within the rotatable range, the fixed base 301 and the like are destroyed. Even when replacement is necessary, the housing 1a It is not necessary to or removed from the back plate 1c of the fixed base 301 to destroy, it is possible to reuse a housing 1a.

  In addition, since the movable base 302 can be attached to and detached from the fixed base 301 unless the substrate case 200 is attached, a predetermined part is damaged or destroyed due to, for example, a turning operation or an illegal act. When the shaft support groove 320 is worn due to friction with the rotation shaft 333 or the like, it is possible to easily remove it from the fixed base 301.

  Further, since the detachment of the movable base 302 from the fixed base 301 can be regulated by using the attachment of the substrate case 200 to the movable base 302 by the one-way screw 240a, the movable base 302 can be simply removed from the movable base 302. In addition to the one-way screw 240a for attaching the substrate case 200 to the movable base 302, a means for regulating the separation of the rotating shaft 333 from the shaft support groove 320 can be removed. Therefore, not only can the structure of the case support device 300 be simplified, but also the work load can be reduced.

  In addition, since the substrate case 200 is attached to the movable base 302 with the one-way screw 240a that cannot be removed once attached to the attachment base 315, the cutting piece 233 is cut to attach the attachment sealing piece 230 to the substrate case 200. The substrate case 200 cannot be removed from the movable base 302 unless it is separated from the main body or the mounting base 315 or the like that is a part of the movable base 302 is destroyed. When the substrate case 200 is detached from the movable base 302 by separating the stop piece 230 from the main body of the substrate case 200, the attachment sealing piece 230 separated from the substrate case 200 is attached to the attachment base 315 together with the one-way screw 240a. The mounting sealing piece 230 is not a single member, but a movable base. Since remaining mounting base 315 of 302, it can be discarded along with the mounting base 315.

  In this embodiment, the mounting base 315 having mounting holes 316a and 316b as mounting portions of the movable base 302 to which the mounting sealing piece 230 as the mounted portion of the substrate case 200 and the preliminary mounting sealing piece 231 are mounted is provided. Since it is provided so that it can be attached to and detached from the movable base 302, even when the substrate case 200 is removed twice, if the mounting base 315 is replaced, the movable base 302 can be used without replacement. Although possible, the mounting holes 316 a and 316 b may be formed directly in the movable base 302.

  Further, the movable base 302 can be easily rotated from the fixed base 301 by performing the same operation as rotating the substrate case 200 without rotating it to the attaching / detaching position C (third position), that is, performing a special removing operation. In addition, the plate-shaped piece 221 serving as the shaft restricting portion directly contacts the rotating shaft 333 at least in the attachment / detachment position, thereby restricting the separation from the shaft support groove 320. Since it is not necessary to provide an attaching / detaching position outside the movable range, the rotatable range of the substrate case 200 can be made as small as possible.

  In addition, since the plate-like piece 221 that covers the rotation shaft 333 can be used as a detachment restricting portion, not only can the structure of the substrate case 200 be simplified, but the plate-like piece 221 can be used as the substrate case 200. Is attached to the movable base 302 by the one-way screw 240a, the left side of the substrate case 200 is locked by the locking plate 323 as a locking portion, so that the one-way screw 240a is not provided on both the left side and the right side. The left and right short sides of the substrate case 200 can be attached to the movable base 302.

  Further, by using the attachment of the substrate case 200 to the movable base 302 by the one-way screw 240a, the rotation shaft 333 can be covered with the plate-like piece 221 as the shaft covering portion, so that the shaft covering portion is previously formed on the fixed base 301 or the like. Therefore, the movable base 302 can be easily assembled to the fixed base 301 at the time of manufacture, and it is not necessary to provide a means for attaching the shaft covering portion separately from the one-way screw 240a. Not only can it be simplified, but the workload can be reduced.

(Modification)
23 and 24 show a substrate case 2000 as a modification of the first embodiment. In the first embodiment, the substrate case 200 is attached to the movable base 302 so that the attachment / detachment position C located within the rotatable range between the first rotation restricting position A and the second rotation restricting position B is provided.
