Description

  The present invention relates to a slot machine capable of generating a predetermined winning according to a display result of a variable display device capable of variably displaying a plurality of types of symbols each identifiable.

  A slot machine generally includes a variable display device having a plurality of reels having a plurality of types of identification information drawn on the outer periphery, and each reel starts to rotate by operating a start lever. Further, when the player operates a stop button provided corresponding to each reel, the rotation is stopped within a predetermined maximum delay time from the operation timing. A winning is generated according to the display result derived when the rotation of all reels is stopped.

  The types of winning combinations include small roles that accompany game value such as medals, re-playing roles that allow the next game to be started without setting the number of bets (replay), regular bonuses and big bonus games. There is a special role (bonus) with a game state advantageous to the player.

  This type of slot machine performs an internal lottery that determines whether or not to allow a prize to be generated almost simultaneously with the start of the game, and the winning of the winning prize is allowed on condition that the internal lottery is won. Things are common. In addition, in a game shop that installs and operates this type of slot machine, it is necessary to change the stage of the winning probability of the installed slot machine in order to adjust sales, so in such a slot machine, A setting value that is a value indicating the stage of the winning probability applied as the lottery probability of the above-described internal lottery can be selected and set from a plurality of values having different probabilities by the operation of an amusement store employee or the like. It has become.

  The slot machine is equipped with a control unit composed of a microcomputer or the like for controlling the game, and the internal lottery is also performed by this control unit. In addition, the control unit is provided with a memory (RAM) that can rewrite data for controlling the game, and the setting value selected and set by the operation of the game shop employee or the like is also stored in this memory. For example, if the memory data is not backed up when the power is turned on, if the memory data is corrupted, or if a reset occurs due to a malfunction of the microcomputer (CPU runaway, etc.) In such a case, it is impossible to return to the original state, so that the storage state of the memory is initialized. Of course, since the setting value is also stored in the memory, it is impossible to restore the setting value that was originally set.

  For this reason, in the conventional slot machine, when an abnormality occurs in the memory data, the memory data is initialized, and the set value includes a predetermined set value (for example, a winning probability with a payout rate close to 100%). And a setting value that determines the winning probability that the payout rate is the lowest) are automatically set to return to a state in which the game can proceed (see, for example, Patent Document 1). In addition, after a preset set value is automatically set, the game can be progressed by a reset operation (mainly an operation for releasing an error or releasing a stop state) by a game shop employee or the like (For example, refer to Patent Document 2).

JP-A-6-114140 JP 2000-296200 A

  However, in the slot machines as described in Patent Documents 1 and 2, if an abnormality occurs in the data in the memory, the set value is selected and set by an operation of an amusement shop employee or the like as described above. Instead of the set value, a preset set value is automatically set to return to a state in which the game can proceed, so the setting that was originally selected and set by the game store operation If an internal lottery should be allowed by applying the winning probability based on the value and the occurrence of a prize should be allowed, but an abnormality occurs in the data in the memory, the employee of the amusement shop will be the same as when an error occurred normally The game is restored to a state in which the game can proceed by performing a reset operation, etc., and an internal lottery is performed by applying a winning probability based on a predetermined set value automatically set by the control of the slot machine This To become. In other words, the game should be played based on the setting value automatically set by the slot machine due to a malfunction of the slot machine, where the game should be played based on the setting value selected by the game shop side. There was a problem that the fairness of the game was lost. It has also been desired to prevent fraudulent acts on data stored in a rewritable memory for controlling the game.

  The present invention has been made paying attention to such problems, and provides a slot machine capable of achieving fairness of a game and preventing illegal acts on data for controlling a game. For the purpose.

In the slot machine (1) in which one game is completed by displaying and displaying the display result of the variable display device (reels 2L, 2C, 2R), and a winning can be generated according to the display result of the variable display device. There,
The main control means (main control unit 41) for controlling the game is provided,
The main control means includes
Data storage means (RAM 41c) having a storage area for storing data for controlling the game in a readable and writable manner;
Plural types of permissible stages having different ratios (winning probabilities) for determining whether or not the derivation of the winning display result corresponding to the winning is permitted based on the operation of the predetermined setting operation means (reset / setting switch 36) An allowable stage selection means (setting change process by the CPU 41a) for selecting any of the allowable stages,
The permissible step setting means (CPU 41a in the setting change process) sets the data indicating the permissible step selected by the permissible step selection means in the permissible step storage area (set value work) assigned to the storage area of the data storage means. Store the confirmed set value in the set value work)
Before the display result of the variable display device is derived, the data indicating the allowable stage stored in the allowable stage storage area (the set value stored in the set value work) is read, and the read data indicates Predetermining means (CPU 41a is set in the internal lottery) for determining whether or not to allow the derivation of the winning display result including the special winning accompanied by the transition to the special gaming state advantageous to the player at a ratio according to the allowable stage. Read out the value, and determine whether or not the winning combination including a plurality of types of special roles is won according to the winning probability of the read setting value),
Stored data determination means (determination of RAM parity and determination of destruction diagnosis data by the CPU 41a) for determining whether or not the data stored in the data storage means is normal when the main control means is activated;
Disabling means for disabling the progress of the game when the stored data determining means determines that the data stored in the data storing means is not normal (when the CPU 41a determines that the RAM data is abnormal) RAM error error state)
In a state where the progress of the game is disabled by the disabling means, the progress of the game is performed on the condition that the allowable stage is newly set by the allowable stage setting means based on the operation of the setting operation means. The disabling canceling means for canceling the disabled state and allowing the game to proceed (when the CPU 41a shifts to the RAM abnormal error state, the setting value is newly selected and set by the setting changing process, so that the game Return to processing)

It is characterized by that.
According to this feature, when an abnormality occurs in the data stored in the data storage means, the progress of the game is disabled, and an allowable stage (set value) is newly set based on the operation of the setting operation means. If the game is not selected or set, the state where the progress of the game is disabled is not released. That is, even if an abnormality occurs in the data stored in the data storage means, it is not an allowable stage automatically set by the slot machine, but an allowable stage selected and set based on the operation of the setting operation means (general In addition, since the operation of the setting operation means is operated by an amusement shop employee, it is ensured that the game is played based on the permissible stage selected by the amusement shop side), so that the fairness of the game is achieved. In addition to being able to do so, it is possible for a game store employee to reliably recognize that an abnormality has occurred in the data stored in the data storage means. Further, since it is necessary to open the second frame in order to perform some fraud on the data stored in the data storage means, an open signal is output based on detection of the opening of the second frame. In other words, it is possible to detect that there is a possibility that an illegal act as described above has been performed, and further, it is possible to detect the opening of the second frame even when the power supply to the slot machine is stopped. Even when the power of the slot machine is turned off, for example, outside of business hours, it is possible to discover that there is a possibility that fraud has been performed by detecting the opening of the second frame.
Note that the predetermined number of bets is at least one bet number, and a game can be started by setting a bet number of two or more or setting a maximum bet number. good. Further, the game may be started by setting a bet amount determined according to a plurality of game states.
Further, the disabling canceling unit is configured to execute the progress of the game on the condition that after the progress of the game is disabled by the disabling unit, the allowable stage is newly set by the allowable stage setting unit. It was supposed to cancel the disabling and allow the game to progress,
The disabling cancellation means is provided on the condition that after the progress of the game is disabled by the disabling means, the control state of the slot machine is controlled to the initial setting state by the initial setting state control means. The progress of the game may be disabled and the game may be allowed to proceed.
In this case, even if the allowable level is not newly set by the allowable level setting means, the disabling of the progress of the game is canceled on the assumption that the allowable level can be set by a predetermined allowable level setting operation. Therefore, it can be ensured that the game is played based on the newly set allowable stage.
Further, the disabling cancellation means is provided on the condition that the game state initialization processing is performed by the gaming state initialization processing means after the progress of the game is disabled by the disabling means. It is also possible to cancel the disabling of the progress of the game and allow the game to proceed.
In this case, since the data stored in the storage area is surely initialized before the disabling of the progress of the game is released, the game is not played with the data in an abnormal state.
Further, the disablement canceling means is configured such that after the progress of the game is disabled by the disablement means, the control state of the slot machine is controlled to the initial setting state by the initial setting state control means, and On the condition that the gaming state initialization processing is performed by the gaming state initialization processing means, the disabling of the progress of the game may be canceled to allow the progress of the game.
In this case, even if the allowable level is not newly set by the allowable level setting means, the disabling of the progress of the game is canceled on the assumption that the allowable level can be set by a predetermined allowable level setting operation. Therefore, it is possible not only to ensure that the game is played based on the newly set allowable stage, but also to ensure that the data stored in the storage area is released before the progress of the game is disabled. Therefore, the game is not played with the data in an abnormal state.

  Similar to the CPU 41a of the main control unit 41, the CPU 91a of the sub control unit 91 has an interrupt function (including an interrupt prohibition function) such as a timer interrupt. An interrupt terminal (not shown) 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 command transmission lines. 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. The CPU 91a executes a timer 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. Also, when an unused interrupt occurs in the CPU 91a, an unused interrupt process for immediately returning to the original process is executed.

  Further, unlike the CPU 41a, the CPU 91a of the sub-control unit 91, when an interrupt is generated based on the input of the strobe signal (INT), is executing an interrupt process based on another interrupt. Then, the command reception interrupt process is executed by interrupting the process, and the command reception interrupt process is executed with the highest priority even if other interrupts occur simultaneously.

  The sub-control unit 91 is also supplied with backup power at the time of a power failure, and while the backup power is supplied, the CPU 91a performs a refresh operation so that the data stored in the RAM 91c is retained. It has become.

  Further, backup power is supplied to the clock device 97 in the event of a power failure, and the date / time information is not reset unless the power failure state continues for 2 to 3 days, for example. The CPU 91a of the sub control unit 91 can perform a predetermined date setting operation when the date and time information is not set by the clock device 97 when the sub control unit 91 is activated, that is, when the date and time information is reset. The date and time setting operation screen (not shown) is controlled to be displayed on the display screen of the liquid crystal display 51 as a display means.

  The setting of the date and time (date, time) of the clock device 97 mounted on the effect control board 90 is, for example, an effect control board 90 into which a connector of a wiring extending from the game control board 40 (effect relay board 80) is inserted. An external clock device (not shown) is connected to the upper connector, and the sub-control unit 91 monitors the acquisition of a date / time setting command indicating the date / time information output from the external clock device. The date and time setting of the timepiece device 97 mounted on the effect control board 90 may be performed based on the acquisition of the date and time setting command output from. In this way, for example, an operation switch for adjusting the date and time is provided on the production control board 90, and the date and time can be easily set even if the operator does not set the date and time by operating the operation switch while looking at the external clock. Can be done.

  The door opening detection circuit 98 includes a door opening detection IC 98a that can monitor the detection status of the door switch 28 independently of the sub-control unit 91. When the door opening detection IC 98a receives a door opening signal from the door switch 28, that is, when the front door 1a is opened, the door opening detection IC 98a acquires the date and time information (date and time) at that time from the clock device 97, The stored date and time information is stored as door opening history information in a storage unit such as a RAM (not shown) provided in the door opening detection IC 98a. The door opening history information (date / time information) stores only a predetermined number of information (for example, 10), and when a predetermined number of information is already stored. In the stored history information, the oldest history information is erased and the latest history information is stored.

  When the CPU 91 a requests acquisition of door opening history information when the sub control unit 91 is activated, all the door opening history information stored in the RAM at that time is output to the sub control unit 91. As a result, all door opening history information is stored in the door opening history area in the RAM 91c of the sub-control unit 91, and the history information is updated.

  When the CPU 91a requests acquisition of door opening history information, the door opening history information stored in the door opening history area in the RAM 91c and the door opening history information stored in the door opening detection IC 98a are identical. It may be determined whether or not the door opening history information is matched, and the door opening history information may be acquired only when it is determined that they do not match, that is, when the door opening history information is updated.

  The door opening detection IC 98a is also supplied with backup power in the event of a power failure, as will be described later, so that even if the opening of the front door 1a is detected in the event of a power failure, the door opening history information Since (date information) is stored in a RAM (not shown) inside the door opening detection IC 98a, the door opening history information stored at the time of a power failure is stored in the RAM 91c when the sub control unit 91 is activated. , Is supposed to be updated.

  In addition, the CPU 91a of the sub-control unit 91 is a predetermined menu screen (not shown) that allows browsing of the date and time setting operation screen, door opening history information, setting change history information, and the like when the sub-control unit 91 is activated. Is displayed on the display screen of the liquid crystal display 51, and when any one of the various menu items displayed on the menu screen is selected, processing corresponding to the selected item is performed. To do.

  In other words, when a date / time setting item is selected from the various menu items displayed on the menu screen, a date / time setting operation screen is displayed, which enables setting of date / time information, and when a door opening history item is selected. The door opening history information browsing screen is displayed, it is possible to browse the door opening history information, and when the setting change history item is selected, the setting change history information browsing screen is displayed, and the setting change history information can be viewed. Become.

  Furthermore, when the selection switch 56 or the decision switch 57 is detected in a period other than during the game (the period from the start of the game to the end of the game), a predetermined menu screen (not shown) is displayed on the liquid crystal display. When one of the various menu items displayed on the menu screen is selected, processing corresponding to the selected item is performed.

  In this embodiment, when the date and time information of the clock device 97 is not set when the sub-control unit 91 is activated, that is, when the date and time information is reset, the date and time setting item is selected on the menu screen. The menu screen cannot be cleared until the date / time information setting operation is performed. Accordingly, since it is possible to avoid storing door opening history information or the like in a state where the date and time information of the clock device 97 is not set, history management can be thoroughly performed.

  Moreover, the opening of the front door 1a can be detected by the door switch 28 in any state where power is supplied to the slot machine 1 (when power is supplied) and power supply is stopped (when power is lost). It is like that. When the opening of the front door 1a is detected, the date and time information when the opening is detected as described above is stored in the RAM (storage unit) in the door opening detection circuit IC98a as the door opening history information, and the front door. Since the door opening signal indicating that 1a has been opened is output to an external device (for example, a hall computer installed in the amusement store) via the external output board 110, it is installed in the amusement store. In addition, the open state of the front door 1a at the time of energization and power failure of each of the plurality of slot machines 1, that is, the open state of the front door 1a at the time of business operation and closing of the store is collectively managed in an external device installed outside the slot machine 1. Can be done.

A cable-side connector 610f is provided at one end of the cable 600d. The cable-side connector 610f is a connector that can be connected to a board-side connector 620f fixed to the external output board 110.

  As described above, each board and each cable includes a pair of connectors (male connector and female connector) including board side connectors 620a to 620f provided on the board side and cable side connectors 610a to 610f provided on the cable side. The wiring connection can be released by removing the cable side connector from the board side connector. In particular, the power supply board 100 and the effect control board 90 are attached to predetermined locations on the housing 1b or the front door 1a of the slot machine 1, so that the cable side connector can be easily removed from the board side connector. 40 and the production control board 90 can be easily replaced.

  In this embodiment, the connector connection between the power supply board 100 and the door switch 28, the power supply board 100 and the effect control board 90, the power supply board 100 and the external output board 110, and the external output board 110 and an external device (not shown) is released. By restricting with a connector restricting member (not shown), it is difficult to release the connection with all the connectors related to detection of opening of the front door 1a.

  Specifically, this connector restricting member is used for connector connection between the power supply board 100 and the door switch 28, that is, for connection between the board side connector 620a of the power supply board 100 and the cable side connector 610a of the cable 600a. Restricts disconnection. Further, the connector connection between the power supply board 100 and the effect control board 90, that is, the connection between the cable side connector 610b of the cable 600b and the board side connector 620b of the power supply board 100, the cable side connector 610c of the cable 600b and the effect control board 90. For the connection with the board-side connector 620c, the release of the connection between these connectors is regulated. Further, the connector connection between the power supply board 100 and the external output board 110, that is, the connection between the cable side connector 610d of the cable 600c and the board side connector 620d of the power supply board 100, the cable side connector 610e of the cable 600c and the external output board 110. In connection with the board-side connector 620e, the release of the connection between these connectors is regulated. Further, the connector connection between the external output board 110 and an external device (not shown), that is, the connection between the board side connector 620f of the external output board 110 and the cable side connector 610f of the cable 600d, is restricted from being released from the connection between these connectors. ing.

  Although such a connector restricting member is not particularly shown in detail, the connector restricting member is configured to be able to restrict the removal of the cable-side connector from the board-side connectors connected to each other, and does not destroy the release restricting portion related to the connection with the connector. As long as it forms a connection release restriction state that makes it impossible to release, that is, if it is configured to leave a trace when the connection release restriction state is released, its form is arbitrary and can be changed variously is there.

  Specifically, for example, it may be a cover body that is formed separately from the board-side connector and the cable-side connector and that can be attached and removed in a connected state to restrict the connector from being removed. Alternatively, it may be a locking portion that is provided on at least one of the board-side connector and the cable-side connector and that cannot be detached from each other when the connectors are connected to each other, or the board-side connector is mounted. In a restricting portion or the like that is provided in a substrate storage case or the like that can store a substrate to be connected, and that forms a connection release restriction state that restricts connector removal when the substrate is stored in the substrate storage case and sealed. It may also be an adhesive or the like that bonds the connectors connected to each other.

  By doing so, the door opening signal cable, that is, any of the cables 600a to 600d is disconnected to prevent the door opening signal from being output to an external device such as a hall computer. In addition, in the unlikely event that the connector connection is released, the trace remains, so that it is possible to surely find that there is a possibility that fraud has been performed.

  Further, for example, when the wiring connection between the power supply board 100 and the effect control board 90, the wiring connection between the power supply board 100 and the external output board 110, and the wiring connection between the external output board 110 and the external device pass through a plurality of relay boards. It is preferable to restrict the removal of all connector connections existing in the meantime. By doing in this way, it is possible to make it difficult to release the connection at all the connectors involved in detecting the opening of the front door 1a.

  Next, the power supply board 100 in FIG. 3 is shown to be connected only to the game control board 40, the external output board 110, the hopper tank, and the switches 28, 29, and 34 to 39, but to other parts. The company also supplies power. The power supply board 100 is connected to a hopper tank that is provided inside the slot machine 1 and includes a hopper motor 34 that performs a medal payout operation and a payout sensor 35 that detects a medal payout. The hopper tank has a function of discharging the medals stored in the hopper tank for storing medals to the outside from the medal payout opening 71 by rotating the hopper motor 34 and detecting the discharged medals by the payout sensor 35. Although the case where the hopper motor 34 in the present embodiment is a DC (Direct Current) motor will be described, the present invention is not limited to this, and any motor may be used as long as it is a DC motor driven by a DC voltage. The hopper tank stores medals inserted by employees of the amusement store and medals inserted from the medal slot 13.

  The power supply board 100 transforms an AC 100V external power supply voltage and supplies operating power to the game control board 40 and other parts of the slot machine 1. The power supply board 100 includes a rectifier circuit that converts an AC voltage of AC 100V supplied from the outside into a DC voltage, a transformer that transmits the DC voltage converted by the rectifier circuit to an internal circuit, and a DC voltage that is transmitted via the transformer. Voltage generation circuit that generates and outputs a plurality of types of DC voltages (24V, 12V, 5V, etc.) having different voltage magnitudes, and hopper control for controlling the hopper tank based on the ON / OFF state of the hopper control signal The circuit 100a is mounted. The hopper tank is connected to a hopper control circuit 100a mounted on the power supply substrate 100 by a connector.

  Of the DC voltage supplied from the power supply substrate 100, a DC voltage of 24V is used as a driving power source for driving the hopper motor 34. The DC voltage of 12V is used as a conduction power source for controlling ON / OFF of a switch element that short-circuits the hopper motor 34. The hopper control circuit 100a performs drive control to rotate the hopper motor 34 by supplying a DC voltage of 24V based on the change of the hopper control signal to the ON state. Further, the hopper control circuit 100a applies a brake to stop the rotation of the hopper motor 34 by connecting the one input terminal and the other input terminal of the hopper motor 34 based on the change of the hopper control signal to the OFF state. Perform brake control. A specific circuit configuration for performing such drive control and brake control will be described with reference to FIG. In addition, the DC voltage generated in the power supply board 100 is supplied to the game control board 40, the effect control board 90, and the like, and is used as a drive power source for various connected electrical components.

  Here, the hopper control circuit 100a will be described with reference to FIG. FIG. 5 is a diagram for explaining a specific circuit configuration of the hopper control circuit 100a. The hopper control circuit 100a serves as a line L1 as an input / output unit for transmitting / receiving a predetermined signal and the like to / from the game control board 40 via the power supply board 100 and a power supply part to which the power generated by the power supply board 100 is supplied. To L8.

  The line L1 is a line for transmitting a payout detection signal from the payout sensor 35 of the hopper tank to the game control board 40 via the power supply board 100. The line L2 is a line formed so that a connection determination current used for determining whether or not the hopper control circuit 100a and the hopper tank are normally connected by the connector flows. The line L3 is a line to which driving power (+ 24V) generated in the power supply substrate 100 is supplied. The line L5 is a line to which the hopper control signal output state specifying power (+ 12V) generated in the power supply substrate 100 is supplied. The line L6 is a line that is electrically connected to the game control board 40 and is used by the game control board 40 to control the ON / OFF state of the hopper control signal. The line L7 is a line for transmitting a state specifying signal for specifying the ON / OFF state of the hopper control signal to the game control board 40. The line L8 is a line for transmitting a supply specifying signal for specifying whether power is supplied to the hopper motor 34 to the game control board 40.

  The connectors for connecting the hopper control circuit 100a and the hopper tank are provided with lines L9 to L12 as a power supply unit to which power is supplied and an input / output unit for transmitting and receiving predetermined signals and the like. It has been. In a state where the hopper control circuit 100a and the hopper tank are normally connected, the lines L9 to L12 provided in the connector on the hopper control circuit 100a side correspond to the corresponding lines provided in the connector on the hopper tank side. And electrically connected.

  The line L9 is a line to which a payout detection signal from the payout sensor 35 of the hopper tank is input. The line L10 is a line formed so that a connection determination current flows when the hopper control circuit 100a and the hopper tank are normally connected by the connector. The line L11 is a line for supplying driving power (+ 24V). The line L12 is a line for connecting to the ground (GND) of the hopper control circuit 100a.

  The payout detection signal from the payout sensor 35 is transmitted to the game control board 40 via the lines L8 and L9 in a state where the hopper control circuit 100a and the hopper tank are normally connected. The connection determination current is formed to flow through the line L2, the resistor R9, the line L10, and the line L12 in a normally connected state.

  The hopper control circuit 100a includes a transistor TR1 that supplies driving power supplied from the line L3 to the one input terminal of the hopper motor 34 by a switching operation, a photocoupler PC1 that controls ON / OFF of the transistor TR1 by a switching operation, A transistor TR2 that controls electrical connection between a line L11 connected to one input terminal of the hopper motor 34 and a line L12 connected to the other input terminal by a switching operation, and a series connection between the node N1 and the ground. The resistor R6 and the resistor R7 provided in the photocoupler, the photocoupler PC2 for controlling the electrical connection between the node N1 and the ground without switching through the resistor R6 and the resistor R7 by the switching operation, and the above-described state specifying signal is output. Comparator CP1 for A hopper control circuit when an abnormal voltage is generated between the comparator CP2 for outputting the supply specifying signal and the line L11 connected to one input terminal of the hopper motor 34 and the line L12 connected to the other input terminal. VRD1 for protecting 100a, a capacitor C1 for charging electric charges by a power source branched from a driving power source supplied from a line L3 via a transistor TR1, and a node N2 and ground by a switching operation via a resistor R7 And a transistor TR3 for performing electrical connection control.

  The transistor TR1 is a P-channel MOS transistor. The source side of the transistor TR1 is connected to the line L3 via the diode D2. The gate of the transistor TR1 is electrically connected to a node between the diode D2 and the source side of the transistor TR1 through the resistor R4. The drain side of the transistor TR1 is connected to a line L11 connected to one input terminal of the hopper motor 34.

  The anode side of the photocoupler PC1 is connected to the line L5 via the resistor R1. The hopper control signal in the present embodiment refers to a voltage applied by supplying a hopper control signal output state specifying power source to the anode side of the photocoupler PC1. When the hopper control signal is in the ON state, the hopper control signal output state specifying power source (+ 12V) is at the voltage level reduced by the resistor R1 on the anode side of the photocoupler PC1, and the photocoupler PC1 is turned on. A state in which a voltage at a voltage level is applied. On the other hand, when the hopper control signal is in the OFF state, the voltage level voltage that turns off the photocoupler PC1 is applied to the anode side of the photocoupler PC1, or the voltage is not applied. . The collector side of the photocoupler PC1 is connected to the gate of the transistor TR1 through the resistor R3. The emitter side of the photocoupler PC1 is connected to the ground.

  The node N1 is connected to the line L4 through the resistor R5. The transistor TR2 is an N-channel MOS transistor. The gate of the transistor TR2 is connected to the node N2 between the resistors R6 and R7 via the node N3. The drain side of the transistor TR2 is connected to a line L11 connected to one input terminal of the hopper motor 34 via a resistor R8. The source side of the transistor TR2 is connected to the ground.

  The cathode side of the VRD 1 is connected to a line L 11 connected to one input terminal of the hopper motor 34. The anode side of VRD1 is connected to the ground. As described above, the VRD 1 protects the hopper control circuit 100a when an abnormal voltage is generated between the line L11 connected to one input terminal of the hopper motor 34 and the line L12 connected to the other input terminal. belongs to. If an abnormal voltage occurs, VRD1 is short-circuited with line L11 and line L12 connected. For this reason, after the abnormal voltage is generated, the same effect as that in a state in which brake control described later is performed is obtained.

  The reference voltage side of the comparator CP1 is connected to the ground, and the input voltage side is connected to the cathode side of the photocoupler PC1. The reference voltage side of the comparator CP2 is connected to the ground, and the input voltage side is connected to a line L11 connected to one input terminal of the hopper motor 34.

  Capacitor C1 has one input terminal connected to the drain side of transistor TR1 via node N1, resistor R5, and diodes D3 and D4, and the other input terminal connected to the ground.

  The transistor TR3 is an NPN bipolar transistor. The base of the transistor TR3 is connected so that a voltage branched from the driving power supply and divided by the resistors R11 and R12 is applied. The collector side of the transistor TR3 is connected to the node N2. The emitter side of the transistor TR3 is connected to the ground.

  Next, the operation of the hopper control circuit 100a will be described. When the power of the slot machine 1 is turned on, the driving power is supplied to the line L3 and the hopper control signal output state specifying power is supplied to the line L5.

  First, the operation for paying out medals will be described. When paying out medals, the game control board 40 is controlled so that the line L6 is in a closed state (a state in which current flows), and the hopper control signal is controlled to be in an ON state. When the hopper control signal is controlled to be in the ON state, the hopper control signal output state specifying power supplied to the line L5 is applied to the photocoupler PC1, so that the photocoupler PC1 is in the ON state.

  When the photocoupler PC1 is in the ON state, a voltage is applied to the gate of the transistor TR1, so that the transistor TR1 is controlled to be in the ON state. As a result, the driving power is supplied to the line L11 connected to the one input terminal of the hopper motor 34, so that the drive control of the hopper motor 34 is performed.

  When the transistor TR1 is controlled to be in the ON state and the driving power is supplied to the line L11, the voltage divided by the resistor R11 and the resistor R12 among the power branched from the driving power is applied to the gate of the transistor TR3. Applied and controlled to ON state. When the transistor TR3 is controlled to be in the ON state, the node N2 is connected to the ground via the transistor TR3. Therefore, the transistor TR2 is controlled to be in the OFF state, and the line L11 connected to one input terminal of the hopper motor 34 On the other hand, the line L12 connected to the input terminal is disconnected, and the brake control is not performed. When the transistor TR1 is controlled to be in the ON state and the driving power is supplied to the line L11, the power branched from the driving power is supplied to one input terminal of the capacitor C1 via the diode D4, the resistor R5, and the node N1. Since it is supplied, the capacitor C1 is charged.

  When the state of the hopper control signal is switched from the ON state to the OFF state, that is, when the medal payout is finished, the line L6 is in an open state (a state in which no current flows), and the hopper control signal supplied to the line L5 Since the power for specifying the output state is not applied to the photocoupler PC1, the photocoupler PC1 is turned off.

  Further, when the photocoupler PC1 is in the OFF state, no voltage is applied to the gate of the transistor TR1, so that the transistor TR1 is controlled to be in the OFF state. As a result, drive power is not supplied to the line L11 connected to the one input terminal of the hopper motor 34, and thus the drive control of the hopper motor 34 is completed.

  Further, when the transistor TR1 is controlled to be in the OFF state and switched to a state in which the driving power is not supplied to the line L11, no voltage is applied to the gate of the transistor TR3, so that the transistor TR1 is controlled to be in the OFF state. When the transistor TR3 is controlled to be in the OFF state, the node N2 is disconnected from the ground through the transistor TR3. Further, when the transistor TR1 is controlled to be in the OFF state and switched to a state in which the driving power supply is not supplied to the line L11, the charge charged in the capacitor C1 is discharged and applied to the resistor R6 and the resistor R7. A voltage is applied to the node N2. For this reason, since a voltage is applied to the gate of the transistor TR2, the transistor TR2 is controlled to be in an ON state. As a result, a short state can be established in which the line L11 connected to one input terminal of the hopper motor 34 and the line L12 connected to the other input terminal are connected, and brake control is performed.

  Since the transistor TR2 is in the ON state when the brake control is performed, the line L11 connected to one input terminal of the hopper motor 34 is connected to the ground via the resistor R8 and the transistor TR2. . For this reason, even when a fraudulent act such as inserting a wire or the like into the slot machine and forcibly rotating the payout portion for paying out medals when brake control is being performed, the hopper motor 34 is operated. Since the rotation load is increased by the self-generated electric power, it is possible to make it difficult to rotate the hopper motor 34 illegally, and it is possible to make the illegal act difficult to perform.

  In addition, even when an illegal act of supplying power to the line L11 and driving the hopper motor 34 is performed when the brake control is being performed, an overcurrent is generated and supplied by the illegal act. The fuse of the supplied power source device (power supply board 100, external power source, etc.) is blown, the energization is cut off by the regulator IC, or the power source device is broken. For this reason, it is possible to prevent an unauthorized act of supplying power to the line L11 to drive the hopper motor 34.

  When VRD1 is short-circuited due to the occurrence of an abnormal voltage or the like, the line L11 connected to one input terminal of the hopper motor 34 is connected to the ground via the shorted VRD1 as in the case where the brake control is performed. Connected to. For this reason, even when the VRD 1 described above is short-circuited due to the occurrence of an abnormal voltage or the like, the same effect as described in the case where the brake control is performed is obtained.

  As described above, when the hopper control signal is switched from the ON state to the OFF state, the drive control of the hopper motor 34 is terminated and the brake control is performed, so that the hopper motor 34 is prevented from rotating due to inertia. Thus, the rotation of the hopper motor 34 can be stopped.

  In addition, while the hopper control signal is set to the ON state, the charge charged in the capacitor C1 is discharged as the power supply for conduction, thereby changing the voltage level of the node N3 to a voltage level for controlling the transistor TR2 to be ON. Therefore, it is not necessary to provide a dedicated power supply line for supplying power for conduction, and space saving of the hopper control circuit 100a can be achieved.

  In addition, when a capacitor having a large capacitance is used as the above-described capacitor, the capacitor is charged even when power is not supplied to the gaming machine, such as when driving power is not supplied. In the case where the charge is discharged, by discharging the electric charge, the voltage level of the node N3 can be maintained at a voltage level that controls the transistor TR2 to be ON, and the hopper motor 34 can be made difficult to rotate. Thereby, even when power is not supplied to the slot machine, it is possible to prevent an illegal act of physically rotating the hopper motor 34 to pay out medals.

  In this embodiment, the capacitor C1 is charged when the medal is paid out. However, for example, when a dedicated charging circuit is configured and the medal is not paid out, the capacitor C1 is charged. Alternatively, the capacitor C1 may be charged.

  In the slot machine 1 of this embodiment, the medal payout rate changes according to the set value, and the winning probability of the internal lottery described later is determined according to the set value. Hereinafter, the setting value changing operation will be described.

  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 power is turned on with the setting key switch 37 in the ON state, 1 is displayed as the initial value of the setting value on the setting value display 24, and the setting change mode in which the setting value can be changed by operating the reset / setting switch 38 is set. Transition. When the reset / setting switch 38 is operated in the setting change mode, the setting value displayed on the setting value display 24 is updated one by one (when the operation is further performed from the setting 6, the setting value is returned to the setting 1). . When the start switch 7 is operated, the set value is confirmed, and the confirmed set value is stored in the RAM 41c of the main control unit 41. Then, when the setting key switch 37 is turned off, the state shifts to a state in which the game can proceed.

  In the slot machine 1 of the present embodiment, when the CPU 41a of the main control unit 41 detects a voltage drop signal, a power interruption interrupt process is executed. In the power interruption interrupt processing, the register is saved in a stack of a RAM 41c, which will be described later, and data for destructive diagnosis (5AH in this embodiment) in which any bit is 1 in the RAM 41c of the main control unit 41, that is, other than 0 In addition to storing specific 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 becomes 0, and stored in the RAM 41c. 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 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 On the condition that the data value is also correct, the processing state of the CPU 41a is restored to the state before the power interruption based on the data stored in the RAM 41c, but when the RAM parity is not 0 (in the case of 1) or for destructive diagnosis If the data value is not correct, it is determined that the RAM is abnormal, and a RAM abnormal error code is set in the register to control the RAM abnormal error, thereby disabling the progress of the game. 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 mode described above. It will not be released until

  In the present embodiment, as described above, when the connection between the game control board 40 and the inserted medal sensor 31 is released even at one place, the backup data held in the RAM 41c of the main control unit 41 is stored. Since the destructive diagnosis data is also cleared to 00H, the CPU 41a determines that there is a RAM abnormality error and disables the progress of the game. Also in this case, the RAM abnormality error state is not canceled until a new set value is set in the setting change mode described above.

  Further, the CPU 41a determines whether or not the bet number set in the game in the internal lottery process described later is a bet number corresponding to the gaming state. And even when the set bet number is not the bet number according to the gaming state, it is determined that the RAM is abnormal, and the RAM abnormal error code is set and controlled to the RAM abnormal error state, so that the progress of the game is disabled. It is like that. As described above, 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 setting is made in the setting change mode described above. It will not be released until a value is set.

  Further, the CPU 41a determines whether or not the bet number set in the internal lottery process described later is a bet number corresponding to the gaming state, and whether or not the set value used for the internal lottery is an appropriate value. judge.

  Even when the set bet number is not the bet number according to the gaming state, or when the set value used for the internal lottery is not an appropriate value, it is determined that the RAM is abnormal and the RAM abnormal error code is set and the RAM is set. The game is controlled to an abnormal error state and the progress of the game is disabled. As described above, 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 setting is made in the setting change mode described above. It will not be released until a value is set.

  Further, when the CPU 41a returns the processing state to the state before the power interruption based on the data stored in the RAM 41c at the time of activation, whether or not the winning flag of any special role is set, that is, the power interruption It is determined whether or not any special role has been won before, and if the winning flag for any special role is set, a power-on command is sent to indicate the special role and the sub-control is sent. Instruct the part 91 that the special role is won. On the other hand, if the winning flag for any special combination is not set, a power-on command indicating that the special combination is not won is transmitted. When the sub-control unit 91 receives a power-on command from the main control unit 41 at the time of startup, the sub-control unit 91 performs a notification effect indicating that the special role is won by the liquid crystal display 51 etc. Then, it continues until the special combination wins, but if it is a power-on command indicating that the special combination is not won, it will return to the backed-up performance state.

  Further, the sub-control unit 91 produces the effect even if the backup is normal until it receives a power-on command or an initialization command indicating that the control state of the main control unit 41 has been initialized as will be described later. Without returning to the state, even if another command is received, the production is not controlled accordingly. For this reason, even if the command transmission lines of the main control unit 41 and the sub control unit 91 are disconnected at the time of startup and the main control unit 41 and the sub control unit 91 are connected thereafter, the sub control unit 91 can Since the initialization command is not received, the production control is not performed, and even if the command transmission line of the main control unit 41 and the sub control unit 91 is disconnected at the time of activation, the power-on command is issued on the sub control unit 91 side. It is impossible to avoid the reception of the special announcement and the announcement effect indicating that the special role is won.

  That is, when the main control unit 41 is activated, it returns to the state before the power interruption, and when the special role is elected before the power interruption, a power-on command indicating that the special role is elected is transmitted. When the sub-control unit 91 receives the power-on command indicating the winning, the sub-control unit 91 executes a notification effect indicating the winning of the special role, and avoids receiving the power-on command on the side of the sub-control unit 91 to notify the winning of the special role. Since it is impossible to avoid the execution of the production, when the main control unit 41 is restored to the state before the power interruption and the special role is elected before the power interruption as described above, The winning of special role will be notified.

  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 this embodiment, as will be described later, there are a regular bonus, a normal gaming state, and an RT (replay time) as a gaming state. Among these, 1 is defined as the prescribed number of bets corresponding to the regular bonus. 3 is defined as the prescribed number of bets corresponding to the gaming state and RT. For this reason, when the gaming state is a regular bonus, the game can be started when the betting number is set to 1, and when the gaming state is the normal gaming state or RT, the betting number is set to 3. And the game can be started. In this embodiment, when a specified number of bets corresponding to the gaming state is set, all winning lines L1 to L5 are activated, and the specified number corresponding to the gaming state is If it is 1, all winning lines L1 to L5 are activated when 1 is set as the bet number, and if the specified number is 3 according to the gaming state, 3 is set as the bet number. All winning lines L1 to L5 are activated.

  In the slot machine 1 of this embodiment, when all the reels 2L, 2C, 2R are stopped, the activated pay line (in the present embodiment, all the pay lines are always enabled. The activated winning line is simply referred to as a winning line), and a winning combination is obtained when a combination of symbols called “comb” is arranged. 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 the combination of combinations permitted by the flag is complete, and is invalid in a game having the combination of combinations permitted. In other words, once the special combination winning flag is won, even if the combination of the combination permitted by the flag cannot be made, the winning flag is not invalidated and is carried over to the next game. It becomes.

  FIG. 6 is a diagram showing a winning combination table. The winning combination table is stored in advance in the ROM 41b of the main control unit 41, and the combination numbers (1 to 14) assigned in the order in which the lottery is performed corresponding to combinations of combinations and combinations to be selected in the internal drawing. ) Is registered.

  In the slot machine 1, as a special role, a big bonus (1), a big bonus (2), a regular bonus, a cherry, 1 (1), 1 (2), and a bell as a small role are replayed. Replay is defined as a role. In addition, combinations of combinations in the slot machine 1 include big bonus (1) + cherry, big bonus (2) + cherry, big bonus (1) +1 (1), big bonus (2) +1 (1), Big bonus (1) +1 (2) and big bonus (2) +1 (2) are defined. That is, the total number of combinations of combinations and combinations is 14.

  In the slot machine 1 of the present embodiment, as shown in FIG. 6, the combination and combination of combinations that are the objects of the lottery differ depending on whether the gaming state is the normal gaming state, RT, or regular bonus. Furthermore, when the gaming state is the normal gaming state or RT, whether or not any special role is being carried over (whether or not it is already set in the winning flag of the special role that any special role has been won) ) Also depends on the combination and combination of combinations that are subject to lottery. In this embodiment, a state number corresponding to the gaming state is assigned, and when performing an internal lottery, a state number corresponding to the current gaming state is set, and a role to be a lottery object is determined according to this state number. It becomes possible to specify. Specifically, when no special combination is carried over in the normal gaming state, “0” is set as the state number, and when no special combination is carried over at RT, the state number is set. When “1” is set and any special combination is carried over in the normal gaming state, “2” is set as the state number, and when any special combination is carried over at RT “3” is set as the state number, and “4” is set as the state number in the case of a regular bonus.

  As shown in FIG. 6, when the gaming state is the normal gaming state or RT and no special role is carried over, that is, when the state number is set to “0” or “1”, the big Bonus (1), Big Bonus (2), Regular Bonus, Big Bonus (1) + Cherry, Big Bonus (2) + Cherry, Big Bonus (1) + 1 (1), Big Bonus (2) + 1 (1 ), Big Bonus (1) + 1 (2), Big Bonus (2) + 1 (2), Replay, Cherry, 1 (1), 1 (2), Bell, ie all combinations and combinations of roles Is subject to internal lottery. When the game state is the normal game state or RT and any special role is carried over, that is, when “2” or “3” is set as the state number, replay, cherry, 1 Sheet (1), sheet (2), bell, that is, the combination of the combination and combination after the combination number 10 is the target of the internal lottery. When the game state is a regular bonus, that is, “4” is set as the state number, cherry, one (1), one (2), bell, that is, the combination of the combination and combination after combination number 11 The combination is subject to internal lottery.

  Cherry is awarded when the “Cherry” symbol is derived on any of the winning lines for the left reel in any gaming state, and two medals are paid out in the normal gaming state and RT, and the regular bonus Will pay out 15 medals. If the “Cherry” symbol stops at the upper or lower level of the left reel, the combination of cherries will be aligned on the two winning lines L2 and L4 or the winning lines L3 and L5. Since you won the cherry on the winning line, 4 medals will be paid out in the normal gaming state and RT, but in the regular bonus, even if you win the cherry on the 2 winning lines, Since the upper limit of the number of medals to be paid out in one game is set to 15, only 15 medals are paid out. One (1) is awarded when a combination of “blue 7-red 7-watermelon” is aligned on any of the winning lines in any gaming state, and one medal is awarded in the normal gaming state and RT. In the regular bonus, 15 medals are paid out. One (2) is awarded when the combination of “Red 7-Blue 7-Watermelon” is aligned on any of the winning lines in any gaming state, and one medal is awarded in the normal gaming state and RT. In the regular bonus, 15 medals are paid out. A bell is awarded when a combination of “Bell-Bell-Bell” is placed on any of the winning lines in any gaming state, and in the normal gaming state and RT, eight medals are paid out, and a regular bonus. Will pay out 15 medals.

  Replay is awarded when a combination of “replay-replay-replay” is arranged in any of the winning lines in the normal gaming state and RT. When a replay is won, the medals will not be paid out, but the next game can be started without setting the number of bets again, so the number of bets no longer required to be set in the next game (the regular bonus will not be replayed and will always be 3) This is substantially the same as when three corresponding medals are paid out.

  The regular bonus is awarded when a combination of “red 7-red 7-BAR” is aligned on any of the winning lines in the normal gaming state and RT. When the regular bonus is won, the gaming state shifts from the normal gaming state or RT to the regular bonus. The regular bonus ends when 12 games are consumed, or when 8 games are won (any kind of combination is possible), whichever comes first. While the game state is in the regular bonus, the regular bonus medium flag is set in the RAM 41c.

  The big bonus is awarded when a combination of “red 7-red 7-red 7” or a combination of “blue 7-blue 7-blue 7” is arranged on any of the winning lines in the normal gaming state and RT. . When the big bonus is won, the gaming state shifts to the big bonus. When transitioning to the big bonus, the transition to the regular bonus is performed at the same time as the transition to the big bonus. Controlled by regular bonus. That is, during the big bonus, the regular bonus is always controlled. The big bonus ends when the total number of medals paid out to the player in the big bonus exceeds 465. At this time, the regular bonus is ended regardless of whether the regular bonus end condition is satisfied. While the game state is the big bonus, the big bonus medium flag is set in the RAM 41c.

  When it is necessary to distinguish between the big bonus by “red 7-red 7-red 7” and the big bonus by “blue 7-blue 7-blue 7”, the big bonus (1) and the big bonus (2 ). Further, the regular bonus, the big bonus (1), and the big bonus (2) described above may be collectively referred to simply as “bonus”.

  Further, in this embodiment, in the normal gaming state, when the combination of the display results of the left reel, the middle reel, and the right reel becomes a combination that constitutes a chance chance described later, and at the time of winning a cherry, Only when the special combination is not carried over) and the lottery probability of the small role is the same as in the normal gaming state, but shifts to the replay time (RT) where the winning probability of replay is high. While the gaming state is at RT, the RT flag is set in the RAM 41c. Then, the RT is terminated by reaching the prescribed game number (two games in the present embodiment) without winning any bonus or by winning any bonus before reaching the prescribed game number.

  Hereinafter, the internal lottery of the present embodiment will be described. In the internal lottery, it is determined whether or not the above winning combination is permitted before the display results of all the 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 16383) is acquired as described later. And, for each combination of combinations and combinations determined according to the gaming state, according to the obtained random number for internal lottery and the number of judgment values of each combination of combinations and combinations determined according to the gaming state and setting value Done. In this embodiment, based on the number of judgment values for each combination and combination of combinations, a range of determination values for each of the general combination and special combination, and a range of determination values for the combination of general combination and special combination is won. And the winning in the internal lottery is not exclusive, and a general combination and a special combination may be won simultaneously in one game. However, for special roles of different types, the range of determination values to be won in duplicate is not specified, and special types of different types are drawn exclusively.

  Each combination and combination of combinations determined according to the game state is referred to in the order of combination numbers registered in the winning combination table shown in FIG.

  When the gaming state is the normal gaming state or RT and no special role is carried over, that is, when “0” or “1” is set as the state number, the winning combination table is referred to, Numbers 1 to 14 and combinations of roles, that is, big bonus (1) [number 1], big bonus (2) [number 2], regular bonus [number 3], big bonus (1) + cherry [ Role number 4], Big bonus (2) + Cherry [Role number 5], Big bonus (1) +1 (1) [Role 6], Big bonus (2) +1 (1) [Role 7], Big Bonus (1) +1 (2) [Role 8], Big Bonus (2) +1 (2) [Role 9], Replay [Role 10], Cherry [Role 11], 1 (1 ) [Position number 12], 1 sheet 2) [winning numbers 13, Bell [winning number 14 are sequentially read as a target combination of the internal lottery.

  When the game state is the normal game state or RT and any special combination is carried over, that is, when the state number is set to “2” or “3”, the winning combination table is referred to. Then, the combination of the combination of combination number 10-14, that is, replay [port number 10], cherry [port number 11], 1 sheet (1) [port number 12], 1 sheet (2) [port number 13] , [Bell number 14] are sequentially read out as a target combination for internal lottery.

  Further, when the game state is a regular bonus, that is, “4” is set as the state number, the winning combination table is referred to and combinations of the combinations of the combination numbers 11 to 14, that is, cherry [portion number 11] 1 sheet (1) [port number 12], 1 sheet (2) [port number 13], and bell [port number 14] are sequentially read out as the object lots for internal lottery.

  In the internal lottery, when the number of judgment values determined for the combination or combination of roles and the state number indicating the current gaming state are added to the random number for internal lottery, and the result of the addition overflows In addition, it is determined that the combination or combination of combinations is won.

  Then, when winning of any combination or combination of combinations is determined, the winning flag corresponding to the combination of combination or combination determined to be selected is stored in the internal winning flag storage work (iwin_fIag) assigned to the RAM 41c. Set. The internal winning flag storage work (iwin_fIag) consists of a 2-byte storage area, of which the upper byte is assigned as the special role storing work in which the special role winning flag is set, and the lower byte is general. It is assigned as a general role storage work in which the winning flag of the role is set. Specifically, when any of the roles (special roles) of the role numbers 1 to 3 is won, a special role winning flag indicating that the special role is won is set in the special role storing work, and the general role is stored. Clear the winning flag set for the workpiece. In addition, when any of the role numbers 4 to 9 (special role + general role) is won, a special role winning flag indicating that the special role is won is set in the special role storing work, A winning combination flag indicating that the general combination is won is set in the general combination storing work. If any of the combination numbers 10 to 14 (general combination) is won, a general combination winning flag 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 CPU 41a refers to the table index and table creation data stored in the ROM 41b when the reel starts to rotate 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.

  For the table index, the start address of the area where the data for table creation is stored from the reference address (table_index) 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) The difference up to the address where the index data indicating is stored is 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 (table_index).

  Specifically, Loss, Cherry, 1 (1), 1 (2), Bell, Replay, Big Bonus (1) (+ Loss), Big Bonus (1) + Cherry, Big Bonus (1) + 1 (1), Big Bonus (1) + 1 (2), Big Bonus (1) + Bell, Big Bonus (1) + Replay, Big Bonus (2) (+ Loss), Big Bonus (2) + Cherry, Big Bonus (2) + 1 (1), Big Bonus (2) + 1 (2), Big Bonus (2) + Bell, Big Bonus (2) + Replay, Regular Bonus (+ Loss), Regular Bonus + Cherry, Regular Bonus + 1 (1), Regular Bonus + 1 (2), Regular Bonus + Bell, Regular Bonus + Replay Index data indicating the leading address of the formation data is stored area is stored. Even if the winning status of the combination is different, if the same control is applied (for example, big bonus (1) + replay winning, big bonus (2) + replay winning, regular bonus + replay winning In the case of applying the same control, etc., the same address is stored as index data. In such a case, the stop control table is created by referring to the same table creation data. Will be.

  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 each, and it is necessary according to each status from this specified address. 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) are defined for one reel. These areas are areas 1 to 21 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 1 to 21 from the reel reference position are assigned to symbols on each reel, so symbols 1 to 21 are assigned to each reel. , Area numbers 1 to 21 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 obtained table creation data, and the address of the stop control table for the unreacted reel corresponding to the stop reel and the area number of the stop position of the reel is obtained from the identified table creation data. The stored stop control table for each reel is expanded to create a stop control table for the unstopped reels.

  Next, when the CPU 41a effectively detects any one of the stop switches 8L, 8C, 8R corresponding to the rotating reel, the control for deriving the display result to the corresponding reel will be described. If any of the stop switches 8L, 8C, and 8R corresponding to the rotating reel is detected effectively, the area number of the stop operation position is based on the number of steps from the reel reference position when the stop operation is detected. And the number of sliding symbols corresponding to the area number of the specified stop operation position is obtained by referring to the stop control table of the reel where the stop operation is detected. 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, an area (stop point in the figure) corresponding to the area number that is the stop position ahead of the number of sliding frames from the area (stop operation point in the figure) corresponding to the area number of the stop operation position in which the stop operation is detected. It stops at the stop reference position (in the present embodiment, the lower symbol area of the see-through window 3).

  The table index of this embodiment stores only one address as index data corresponding to one internal winning state in one gaming state. Furthermore, one table creation data includes one table data. Only one address is stored as the storage area address of the stop control table corresponding to the reel 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 a 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. That is, the symbol stop position can be designated from a range of up to five frames including the stop operation position at which the stop operation is detected. In addition, since one frame is required 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 the table index, the number of sliding frames that draws the winning combination as much as possible within the range of 4 frames to the address corresponding to the case where one of the roles is won, and draws the winning combination so that there are no winning combinations. The index data that identifies the data for creating the table for which is defined is stored, and for the table creation in which the number of sliding frames to be drawn so that none of the roles are aligned is stored in the address corresponding to the case where the loss is won Stores index data for specifying data. For this reason, if any winning combination is won, there will be a stop control table in which the winning combination is drawn in the range of 4 frames to the maximum, and the number of sliding symbols to be drawn so that the winning combinations are not aligned is determined. The reel stop control is performed, and if no winning combination is selected, a stop control table in which the number of sliding frames that do not have any winning combination is defined is created, and the reel stopping control is performed. Done. As a result, when the stop operation is performed, if the symbols of the winning combination can be stopped on the winning line in the drawing range of up to 4 frames, the control is performed to align them and stop. The symbol of the winning combination will be controlled to be stopped in a drawing range of a maximum of 4 frames.

  Also, in the table index, the address corresponding to the case where a small role is elected with a special role carried over from before the previous game (Big Bonus (1) + Cherry, Big Bonus (1) + Bell, etc.) The number of sliding frames is determined so that the selected special role can be drawn to the maximum within the range of 4 frames, and the stop operation position where the selected special role cannot be drawn within the range of the maximum 4 frames is selected. The index data for specifying the data for creating the table in which the number of sliding frames is determined so that the maximum number of frames is drawn in the range of 4 frames is stored, and the reel stop control is performed. As a result, when the stop operation is performed, if the symbols of the special roles that have been elected in the drawing range of up to 4 frames can be stopped on the winning line, the control is performed to stop them together. If you can't draw a special role that you have won in the drawing range of up to 4 frames on the winning line, you can align the symbols of the small role that has been won in the drawing range of up to 4 frames on the winning line. If they can be stopped, control is performed to stop them together, and the symbol of the winning combination is controlled to be stopped in the drawing range of 4 frames. That is, in such a case, priority is given to the control for aligning the special combination on the winning line over the small combination, and the small combination can be won only when the special combination cannot be drawn. When a special combination and a small combination can be drawn at the same time, only the special combination is drawn, and the small combination is not arranged on the winning line at the same time as the special combination.

  Also, in the table index, when a re-playing role is won in a state where the special role has been carried over from before the previous game (Big Bonus (1) + Replay etc.), the re-playing role has 4 frames. Index data for specifying data for creating a table in which the number of sliding frames is determined so as to be pulled in as much as possible within the range is stored, and reel stop control is performed. As a result, 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 up to four frames. As will be described later, “replay” which is a symbol constituting the re-gamer is arranged within 5 symbols, that is, within an interval of 4 frames for each of the reels 2L, 2C, 2R. Can be stopped at any position within the pull-in range, so if the special player is carried over from before the previous game, the stop switch 8L, 8C, 8R by the player Regardless of the operation timing, the re-game players will always win together. 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 the case where the special combination and the re-playing combination can be withdrawn at the same time, only the re-playing combination is drawn in, and the special combination is not arranged on the winning line at the same time as the re-playing combination.

  Here, as shown in FIG. 2, the “bell” and “replay” are arranged within 5 symbols, that is, within an interval of 4 frames, for all of the reels 2L, 2C, and 2R. It can be stopped at any position within the range. That is, when the winning flag for the bell and the replay is set, the winning combination can always be won regardless of the operation timing of the stop switches 8L, 8C, and 8R by the player.

  In addition, when the winning flag for replay is set, if the left reel is still rotating, the “Replay” symbol will be used as the stop control table for the middle reel and the right reel. A stop control table for drawing on L2 or L5 is created, and when the “replay” symbol is stopped on at least one winning line L2 or L5 for the middle reel or the right reel, the stop control table for the left reel is 5 The “replay” symbol of the number, that is, when the symbol is stopped on the winning line L2 or L5, the “replay” symbol excluding the “replay” symbol that also stops the “cherry” on the winning line L1. A stop control table is created to draw on the winning line L2 or L5, and the middle reel and right reel are moved from the left reel. When stopped first, the “replay” symbol is drawn on the winning line L2 or L5, and when the left reel is stopped thereafter, the “replay” symbol other than No. 5 is always placed on the winning line L2 or L5. Therefore, for example, when the “replay” symbol No. 5 stops on the winning line L2 or L5 of the middle reel and the right reel, the replay and the cherry are not won simultaneously. In the left reel, the 2nd “Replay” design and the 7th “Replay” design are arranged within 4 frames, so even if control is performed to avoid the 5th “Replay” design, Regardless of the operation timing of the stop switches 8L, 8C, and 8R by the player, the replay can always be won. If the left reel is stopped while all the reels are still rotating when the replay winning flag is set, except for the case where the replay and cherry win at the same time, A stop control table for drawing the “replay” symbol into any of the pay lines L1 to L5 within the drawing range of 4 frames is created. That is, when the left reel is stopped first, control is performed so that the combination of “replay” can be arranged in any of the winning lines L1 to L5.

  In addition, when the winning flag for the bell is set, if the left reel is still rotating, the “bell” symbol is always used as the stop control table for the middle reel and the right reel. A stop control table is drawn in on L1, and when the “bell” symbol is stopped on at least one winning line L1 of the middle reel or the right reel, the “bell” symbol is used as the stop control table for the left reel. A stop control table for drawing on the winning line L1 in the drawing range of 4 frames is created, and when the middle reel or the right reel is stopped before the left reel, the “bell” symbol is drawn on the winning line L1, Thereafter, when the left reel is stopped, the “bell” symbol is always drawn on the winning line L1. In the left reel, the “bell” symbol and the “cherry” symbol are not arranged continuously. For this reason, the bell can always be won regardless of the operation timing of the stop switches 8L, 8C, and 8R by the player, and the bell and the cherry are not simultaneously won. If the left reel is stopped while all the reels are still rotating when the bell winning flag is set, except for the case where the bell and cherry win at the same time, A stop control table for drawing the “bell” symbol into any of the pay lines L1 to L5 within the drawing range of 4 frames is created. That is, when the left reel is stopped for the first time, control is performed so that the combination of “bells” can be arranged in any of the winning lines L1 to L5.

  Next, chance eyes and reach eyes will be described. The chance in the present embodiment is a display mode that can be derived when any bonus is won in the normal gaming state, or when one (1) or one (2) is won. In this embodiment, the display result of the left reel is “replay watermelon bell” of symbols 2-4 or “bell / red 7 bell” of symbols 8-10, “replay” of symbols 15-17. "Blue 7 Watermelon" is stopped, and all the roles are not aligned on the winning line. As a result of displaying the middle reel, "Cherry Replay Cherry" of No. 11-13, 21, 1, 2, The “Cherry Bell Cherry” of the number symbol is stopped, and the display mode in which none of the roles are aligned on the winning line, and the display result of the right reel is “Replay Cherry Blue 7” of the number 10 to 12 symbol. Stop and any Have applied the display mode also not aligned on a winning line as a chance eyes.

  The reach eye is a display mode that can be derived only when any bonus (big bonus (1), big bonus (2), regular bonus) is won in the normal gaming state. As a result of the display on the left reel, the display mode in which “blue 7 / watermelon / blue 7” of symbols 16-18 is stopped is the reach of all bonuses, and symbols 20, 20, 1, 1 or 12-14 The display mode in which the symbol “Replay Watermelon Bell” has stopped and none of the roles are on the winning line is applied as the reach of the big bonus (1) or regular bonus.

  Further, in this embodiment, the CPU 41a regards that the stop operation has been performed even if the reel stop operation is not performed when a predetermined automatic stop time has elapsed since the start of the reel rotation. To automatically stop each reel.

  When the CPU 41a performs the automatic stop control, the CPU 41a performs control to stop with priority in the order of the right reel, the middle reel, and the left reel. That is, when all the reels are rotating, control is performed to stop in the order of right, middle, and left, and when any reel has already stopped, the reels that are still rotating are set to the right, middle, Control to stop in priority order in the left order. In particular, in the present embodiment, a winning combination that is achieved only by stopping “cherry” on the winning line of the left reel, that is, a winning combination that is achieved only by any one reel is determined. Except when the reel in which the winning combination is established alone is already stopped before performing, the control for stopping the reel at the end is performed.

  In addition, in the automatic stop control, except for the reel that stops at the end, refer to the stop control table of the corresponding reel as in the case of the stop operation, and respond based on the number of sliding frames in the referred stop control table. Control is performed to stop the rotation of the reels 2L, 2C, and 2R. In addition, for the reel that stops last, when the stop position corresponding to each area number is immediately stopped for every area number (the number of steps belonging to each area number is stopped with a number of steps less than one symbol. A non-winning position table indicating whether or not any of the winning positions are not aligned on the winning line, and refers to the non-winning position table at regular intervals (about 2 ms). The process of repeatedly determining whether or not the area number to which the number of steps from the reference position belongs is a non-winning position is the earliest when it is determined that the area number to which the current step number belongs is a non-winning position. Control is performed to stop the reel at a stop position that can be stopped at a stage (a range of less than one frame), that is, at a position where the symbol corresponding to the area number stops at the lower stage. For this reason, the last stop reel is stopped immediately without slipping more than one frame when the rotating reel reaches the non-winning position.

  The non-winning position table is set to stop the stopped reels when the two reels except the last reel are stopped after the shift to automatic stop control or when the two reels stop and shift to the automatic stop control. It is created based on the position. Specifically, whether or not any combination stops on the winning line when the symbols of the corresponding region numbers are stopped in the lower row in order from the region numbers 1 to 21 based on the stop positions of the stopped reels. When the symbol of the area number is stopped at the lower stage, if it is determined that none of the winning combinations stop on the winning line, “1” indicating the non-winning position is set as the non-winning position flag. Then, when it is determined that any combination is stopped on the winning line when the symbol of the area number is stopped at the lower stage, a process of setting “0” indicating that it is not a non-winning position is performed. It is created by that. If the cherry is already stopped on the left reel, it is determined whether or not a combination other than the cherry stops on the winning line when the symbol of the area number is stopped at the lower stage. When it is determined that the role other than cherry does not stop on the winning line when the symbol is stopped at the lower stage, “1” indicating the non-winning position is set as the non-winning position flag, When it is determined that the combination other than the cherry is stopped on the winning line when the symbol is stopped at the lower stage, “0” indicating that it is not the non-winning position is set.

  Further, once the automatic stop control is started, the CPU 41a invalidates detection of the operation of the stop switches 8L, 8C, and 8R, and does not enable it until all the reels are stopped thereafter.

  As described above, when the reels are stopped by the automatic stop control, the winning combination is controlled so that the winning combination is not aligned on any winning line regardless of whether or not any winning combination is won in the internal lottery. The Rukoto. In addition, for the reel that stops last, stop control of the reel is not performed based on the stop control based on the stop control table, but based on the smallest number of sliding symbols that do not have any combination on the winning line. Therefore, the reach eyes or chance eyes may stop, but in this case, the stopped reach eyes or chance eyes become invalid. That is, even if the reach is stopped, if it is based on automatic stop control, it does not indicate that any special role is elected, and even if the chance is stopped, it is based on automatic stop control. If so, it does not indicate that there is a high possibility that any special role will be elected.

  The CPU 41a according to the present embodiment performs an abnormal winning determination that determines whether or not a combination that is not permitted in the game is aligned on the winning line when all the reels are stopped. In the abnormal winning judgment, if the roles are arranged in spite of the automatic stop (excluding cherries stopped before shifting to the automatic stop control), if the winning combination is found in the internal lottery, the special role and the general role It is determined that there is an abnormal prize when the two are arranged at the same time. If it is determined that the prize is abnormal, it is controlled to an abnormal prize error state to disable the progress of the game. The abnormal winning error state is not canceled even if the reset switch 23 or the reset / setting switch 38 is operated, as in the case of the RAM abnormal error described above, and a new set value is set in the setting change mode described above. It will not be released until it is set.

  The abnormal winning determination will be described. First, as described above, the CPU 41a sets the winning flag indicating the winning combination in the game in the internal winning flag storing work (iwin_fIag) assigned to the RAM 41c, and all reels. A winning symbol flag is set to indicate the winning combination on the winning line at the time of stopping. Then, an abnormal winning determination flag is created from the winning flag, and it is determined whether or not there is an abnormal winning based on the generated abnormal winning determination flag and the winning symbol flag.

  The winning flag is a 16-bit (2 byte) binary value indicating the winning combination in the game, and when the value of the bit individually determined for each winning combination is 1, Indicates that the winning combination has been won, and when it is 0, the combination has not been won.

  As shown in FIG. 7, the 0th bit corresponds to the big bonus (1), the 1st bit corresponds to the big bonus (2), the 2nd bit corresponds to the regular bonus, the 11th bit is replay, and the 12th bit is 1 Sheet (1), 13th bit corresponds to 1 (2), 14th bit corresponds to Bell, and 15th bit corresponds to Cherry. The third to tenth bits do not correspond to any combination.

  In this embodiment, there are cases where a plurality of winning combinations are won in one game. In this case, the value of each bit corresponding to the winning combination is set to 1 in the winning flag. Yes.

  The abnormal winning determination flag is a 16-bit (2 byte) binary value indicating the winning combination in the game, but the bit value individually determined for each combination is 0. Indicates that the winning combination is won, and when it is 1, it indicates that the winning combination is not won. That is, the abnormal winning determination flag is a value obtained by inverting 0 and 1 of the winning flag.

  The winning symbol flag is a 16-bit (2 byte) binary value indicating the winning combination on the winning line, and when the value of the bit individually determined for each winning is 1, Indicates that a prize has been won, and if it is 0, it indicates that the role has not won. The winning symbol flag is the same as the internal winning flag. As shown in FIG. 7, the 0th bit corresponds to the big bonus (1), the 1st bit corresponds to the big bonus (2), and the 3rd bit corresponds to the regular bonus. The eleventh bit corresponds to replay, the twelfth bit corresponds to one (1), the thirteenth bit corresponds to one (2), the fourteenth bit corresponds to bell, and the fifteenth bit corresponds to cherry. The third to tenth bits do not correspond to any combination.

  In the abnormal winning determination, the CPU 41a first determines whether or not it is automatic stop, and if it is automatic stop, it determines whether or not the value of the winning symbol flag is 0000H. If it is determined in this determination that the value of the winning symbol flag is not 0000H, whether the value of the 15th bit corresponding to cherry in the winning symbol flag is 1 and the values of the other bits are 0, That is, it is determined whether or not the value of the winning symbol flag is 8000H. If the value of the winning symbol flag is 8000H, it is determined whether or not the cherry has stopped before shifting to automatic stop. If the cherry has not stopped before shifting to automatic stop, judge. That is, when the cherry stops on the winning line after shifting to automatic stop, it means that a winning has occurred despite the automatic stop, and therefore, it is determined that there is an abnormal winning. On the other hand, when the value of the winning symbol flag is neither 0000H nor 8000H, it is determined that the prize is abnormal. At the time of automatic stop, none of the roles are aligned on the winning line except for the cherry stopped before the automatic stop transition, the value of the winning symbol flag should be 0000H or 8000H, and the value of the winning symbol flag is 0000H However, if it is not 8000H, any combination other than cherry will be on the winning line, and it will be determined as an abnormal winning.

  Next, if it is not an automatic stop, or if it is not an abnormal winning at the time of automatic stop, a value obtained by performing an OR operation on each bit of the higher byte of the winning symbol and a value obtained by performing an OR operation on each bit of the lower byte , And determine whether the special combination and the general combination are won at the same time. As shown in FIG. 7, since the lower byte of the winning symbol flag is only the bit corresponding to the special role, and the upper byte is only the bit corresponding to the general role, the value obtained by ORing the lower byte is If at least one special role has been won, it will be “1”. If none has been won, it will be “0”. On the other hand, the value obtained by ORing the upper bytes will be won even by one general character. “1” if it has been won, and “0” if it has not been won. Therefore, the result of logical product of the value obtained by logical OR operation of the lower byte and the value obtained by logical OR operation of the upper byte is always “0” except when the special role and the general role are won simultaneously, If this result is “1”, it means that the special combination and the general combination are won at the same time. In this case, it is determined that the prize is abnormal.

  Next, if it is determined that the special combination and the general combination are not won at the same time, it is determined whether or not the combination that is not won is obtained by performing an AND operation on the abnormal winning determination flag and the winning symbol flag. To do. In the abnormal winning determination flag, the value of the bit corresponding to the winning combination in the game is 0, and when this winning combination is won, that is, the value of the corresponding bit of the winning symbol flag is 1. However, even if no winning is made, that is, when the value of the corresponding bit of the winning design flag is 0, the result of the logical product operation is always 0. On the other hand, the value of the bit corresponding to the winning combination that is not won in the game in the abnormal winning determination flag is 1, and when this winning combination is not won, that is, the value of the corresponding bit of the winning symbol flag is 0. In this case, the result of the logical product operation is 0, but when the winning is made, that is, when the value of the corresponding bit of the winning symbol flag is 1, the result of the logical product operation is 1. For this reason, when even one winning combination is won, the result of the logical product operation of the abnormal winning determination flag and the winning symbol flag becomes a value other than 0. In this case, the abnormal winning is determined. To do.

  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 that stores 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 during the big bonus. The special work is a work that stores data to be initialized only before the start of setting, such as data for transmitting a command to the effect control board 90 and various software random numbers. The set value work is a work in which a set value used when performing a lottery in the internal lottery process is stored. After initializing 0 before setting is started (before shifting to the setting change mode), 1 is stored. The set value that is corrected and newly set at the end of the setting (when the setting change mode is ended) is stored. 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 CPU 41a is stored, and the unused stack area is satisfied by any one of a plurality of initialization conditions to be described later, like the unused area. However, the used stack area is not initialized because the program continues.

  In this embodiment, the CPU 41a of the main control unit 41 starts from the four at the end of one game when the data in the RAM 41c is not destroyed before the start of setting (before the transition to the setting change mode), at the end of the big bonus, and at the start. When the initialization condition is satisfied, four types of initializations with different areas initialized according to each initialization condition are performed.

  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 mode. Initialization 1 uses the storage area of the RAM 41c. All areas except the middle 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, a general work, an unused area, and an unused stack area are initialized in the storage area of the RAM 41c. Initialization 3 is an initialization 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. In the initialization 3, the unsaved work, the unused area, and the 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.

  Next, commands that the CPU 41a of the main control unit 41 transmits to the effect control board 90 will be described.

  In the present embodiment, the CPU 41a of the main control unit 41 makes a BET 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 gaming state to the effect control board 90. A plurality of types of commands including a command, a standby command, an abort command, an error command, a setting start command, an initialization command, and a power-on command are transmitted.

  The BET command is a command that can specify the number of medals inserted, that is, the number of medals used to set the bet number. When a medal is inserted, the one-BET switch 5 or the MAX BET switch 6 is operated to set the bet number. Sent when

  The internal winning command is a command that can specify the winning status of the internal winning flag and the type of the internal winning flag that has been established, and is transmitted when the start switch 7 is operated to start the game.

  The reel rotation start command is a command for notifying the start of reel rotation, and is transmitted when rotation of the reels 2L, 2C, and 2R is started.

  The reel stop command indicates whether the reel to be stopped is any of the left reel, middle reel, and right reel, whether it is due to automatic stop, the area number of the stop operation position of the corresponding reel, and the stop position of the corresponding reel. This is a command that can specify the area number, and is transmitted each time stop control of each reel is performed.

  The winning determination command is a command that can specify the presence / absence of winning, the type of winning, and the number of medals to be paid out at the time of winning, and is transmitted after all the reels are stopped and the winning determination is performed.

  The payout start command is a command for notifying the start of payout of medals, and is transmitted when the payout of medals is started by paying out a prize or credit (including medals used for setting the number of bets). The payout end command is a command for notifying the end of payout of medals, and is transmitted when the payout of medals by winning and winning a credit is completed.

  The gaming state command is a command that can specify the gaming state of the next game (whether it is a normal gaming state, a big bonus, a regular bonus, etc.), and is transmitted at the end of the game.

  The standby command is a command indicating a transition to the standby state, and is transmitted when the transition to the standby state is made after a certain time has elapsed without setting the bet amount after the end of one game.

  The stop command is a command indicating the occurrence or release of the stop state, and after the end of the BB, the stop command indicating the occurrence of the stop state is transmitted when the ending effect waiting time has elapsed, and the reset operation is performed. When the stop state is released, a stop command indicating the release of the stop state is transmitted.

  An error command is a command that indicates the occurrence or release of an error state. When an error is determined and controlled to the error state, an error command that indicates the occurrence of the error state is sent, and a reset operation is performed to release the error state. At that time, an error command indicating the cancellation of the error state is transmitted.

  The setting start command is a command indicating the start of the setting change mode, and is transmitted when setting is started, that is, when the mode is changed to the setting change mode.

  The initialization command is a command indicating that the gaming state has been initialized, and is transmitted when the setting ends, that is, when the setting change mode ends.

  The power-on command is a command that indicates whether or not one of the special roles has been won at power-on, and if it can be restored to the state before the power interruption at startup, it returns to the state before the power interruption. Sent at a time before

  Each of these commands is generated in an activation process and a game process described later, temporarily stored in a command queue provided in a special work in the RAM 41c, and transmitted in the timer interrupt process (main) described above.

  Next, the control of the effect performed by the sub control unit 91 based on a command transmitted from the CPU 41a of the main control unit 41 to the effect control board 90 will be described.

  When the CPU 91a of the sub control unit 91 receives a command transmitted by the CPU 41a of the main control unit 41, the CPU 91a refers to the control pattern table stored in the ROM 91b, and displays the liquid crystal display based on the control content registered in the control pattern table. The various effect devices such as the device 51, the effect LED 52, the speakers 53 and 54, and the reel LED 55 are controlled.

  In the control pattern table, the display pattern of the liquid crystal display 51 corresponding to the type of command, the lighting mode of the lighting effect LED 52, the output mode of the speakers 53 and 54, the lighting mode of the reel LED, etc. The control patterns of these effect devices are registered, and when the CPU 91a receives a command, the CPU 91a receives among the control patterns registered corresponding to the effect patterns set in the RAM 91c in the game of the control pattern table. The control device corresponding to the type of the command is referred to, and the rendering device is controlled based on the control pattern. Thereby, the production according to the production pattern and the progress of the game is executed.

  If the CPU 91a receives a new command during the execution of an effect triggered by the reception of a certain command, the CPU 91a stops the effect based on the control pattern being executed, and performs control corresponding to the newly received command. An effect based on the pattern is executed. In other words, even when the effect has not been completed to the end, when a new command is received, the effect that has been executed is canceled and the effect based on the new command is executed.

  When the internal winning command is received, the effect pattern is selected at a selection rate corresponding to the result of the internal lottery indicated by the internal winning command, and is set in the RAM 91c. The selection rate of the effect pattern is registered in the effect table stored in the ROM 91b. When the CPU 91a receives the internal winning command, the CPU 91a is registered in the effect table according to the result of the internal lottery indicated by the internal winning command. The selected selection pattern is selected from a plurality of types of production patterns according to the selection rate, and the selected production pattern is set in the RAM 91c as the production pattern of the game.

  The control pattern table also includes specific commands (reel stop command indicating automatic stop, winning determination command indicating occurrence of winning, payout start command, payout end, gaming state command indicating end of big bonus, standby command, stop Command, error command, setting start command, initialization command, power-on command indicating the winning of special role, etc.) are stored, and the CPU 91a stores these specific commands. When received, regardless of the effect pattern set in the game, the effect device is controlled based on the control pattern with reference to a specific control pattern corresponding to the command.

  When a reel stop command for the last reel to stop is received among the reel stop commands indicating automatic stop, the reel is stopped by automatic stop control. An automatic stop notification pattern for notifying that the reach is invalid and that a small role notification effect described later is invalid is referred to as a control pattern.

  When a winning determination command indicating the occurrence of a winning is received, a winning effect pattern for executing a winning effect according to the type of winning is referred to as a control pattern. In particular, when a winning determination command indicating the occurrence of a big bonus winning is received, a BB winning pattern for executing a BB winning effect peculiar to the big bonus winning is referred to as a control pattern.

  When a payout start command is received, a payout pattern for outputting payout sound effects is referred to as a control pattern. Further, when a payout end command is received during the output of the payout sound effect, the output of the payout sound effect is stopped. When a payout start command is received, unlike the other commands, the effect that is being executed is not executed and the effect corresponding to the received command is not executed. Sound effects are output. That is, other effects and effects accompanying payout are executed in parallel.

  When a gaming state command indicating the end of the big bonus is received, an ending pattern for executing an ending effect indicating the end of the big bonus is referred to as a control pattern.

  When a standby command is received, a standby pattern for executing a standby effect as a demonstration effect is referred to as a control pattern. In addition, when a continuous effect or an additional effect, which will be described later, is being executed, if an effect accompanying a big bonus or a regular bonus is being executed, the execution of the standby effect is prohibited. Even if the standby command is received in such a state, the standby pattern is not referred to as the control pattern, and the standby effect is not executed.

  When a stop command indicating the occurrence of a stop state is received, a stop notification pattern for notifying that the stop state is in effect is referred to as a control pattern. When a stop command indicating release of the stop state is received, the above-described standby pattern is referred to as a control pattern. That is, when the stop state is released, the standby effect is executed.

  When an error command indicating the occurrence of an error state is received, an error notification pattern for notifying the fact of the error state and its type is referred to as a control pattern. When an error command indicating the cancellation of the error state is received, the control pattern that was being executed when the error occurred is referred to. That is, the production at the time of error occurrence is executed from the beginning.

  When the setting start command is received, a setting notification pattern for notifying that the setting is being changed is referred to. When the initialization command is received, the standby pattern described above is referred to as the control pattern. That is, when the initialization command is received, the standby effect is executed.

  When a power-on command indicating that a special role is won is received, a special role notification pattern for notifying that the special role has been won is referred to. That is, when a power-on command indicating that the special role is won is received, a notification effect for notifying that the special role is won is executed. Note that the notification effect for notifying the winning of the special combination is once executed until it receives a winning determination command indicating that the special combination has won.

  The CPU 91a of the sub-control unit 91 performs RAM parity adjustment so that the RAM parity based on the data stored in all areas of the RAM 91c becomes 0 each time the timer interrupt process (sub) that is periodically executed is executed. Data is calculated and stored in the RAM 91c.

  Then, the CPU 91a calculates the RAM parity based on the data stored in all the areas of the RAM 91c at the time of activation, and is based on the data stored in the RAM 91c on the condition that the RAM parity is 0. It is designed to return to the production state before the interruption. Specifically, the control pattern executed last is referred to and control based on the control pattern is executed. As a result, an effect based on the control pattern executed before power interruption is executed from the beginning. Further, when the RAM parity calculated based on the data stored in all areas of the RAM 91c at the time of startup is not 0 (in the case of 1), it is determined that the RAM is abnormal, and all areas of the RAM 91c are initialized. It has become.

  In addition, the CPU 91a receives an initialization command or a power-on command before actually starting the production regardless of whether or not the production state before power interruption can be restored based on the data stored in the RAM 91c at the time of activation. Wait until either is received. If the initialization command is received in this state, the standby effect is executed after clearing the data in the RAM 91c. In addition, when a power-on command indicating that the special role is elected is received in this state, a notice effect indicating that the special role is elected is executed, and when a power-on command indicating that the special role is not elected is received, If it is possible to return to the effect state before the power interruption, it returns, and if it cannot be recovered, the standby effect is executed. Also, in the state of waiting for receiving the initialization command or the power-on command, the execution of the timer interrupt process that executes the presentation based on the reception of the command is not permitted, and even when other commands are received, An effect based on the command is not performed, and no effect is performed until the initialization command or the power-on command is received after the startup and the execution of the timer interrupt process is permitted.

  Next, various control contents executed by the CPU 41a of the main control unit 41 in the present embodiment will be described below with reference to FIGS.

  When the reset signal is input from the reset circuit 49, the CPU 41a performs a startup process shown in the flowchart of FIG. Since the reset signal is a signal output when the power is turned on and when the operation of the main control unit 41 is stagnant, the activation process is performed when the CPU 41a is activated when the power is turned on and when the CPU 41a is activated due to a malfunction. This is a process to be performed.

  In the start-up process, first, the built-in device, peripheral IC, interrupt mode, stack pointer, etc. are initialized (Sa1), then the voltage drop signal detection data is acquired from the input port, and whether or not the voltage drop signal is input. That is, it is determined whether or not the voltage is stable (Sa2), and if the voltage drop signal is input, any processing is performed except for determining whether or not the voltage drop signal is input. There is no loop processing.

  If it is determined in step Sa2 that the voltage drop signal is not input, the values of the I register and IY register are initialized (Sa3), and the states of the stop switch 36 and the automatic settlement switch 29 are acquired. Validity / invalidity of the stop function and automatic settlement function is set in a specific register of the CPU 41a (Sa4). By the initialization of the I register and the IY register, the address of the interrupt table to be referred to when an interrupt occurs is set in the I register, and the reference address for referring to the storage area of the RAM 41c is set in the IY register. . These values are fixed values and are always initialized at startup.

  Next, access to the RAM 41c is permitted (Sa5), and it is determined whether or not the setting key switch 37 is in an ON state (Sa6). If the setting key switch 37 is not in the ON state in step Sa6, the RAM parity of all storage areas (including the unused area and the unused stack area) of the RAM 41c is calculated (Sa7). Is determined (Sa8). If the power interruption interrupt processing (main) is normally performed, the RAM parity should be 0. If the RAM parity is not 0 in the step of Sa8, the data stored in the RAM 41c is not normal. Therefore, an error code indicating a RAM abnormality is set in the register (Sa10), and the process proceeds to the error process shown in FIG.

  If the RAM parity is 0 in step Sa8, it is further determined whether or not the destructive diagnosis data is normal (Sa9). If power interruption interrupt processing (main) is performed normally, the data for destruction diagnosis should have been set. If the data for destruction diagnosis is not normal in step Sa9 (data for destruction diagnosis is power interruption) Since the data in the RAM 41c is not normal also in the case other than 5A (H) stored sometimes, the error code indicating the RAM abnormality is set in the register (Sa10), and the process proceeds to the error processing shown in FIG.

  In the error processing, as shown in FIG. 9, the current display state of the game auxiliary display 12 is saved in the stack (Sb1), and the error code stored in the register is displayed on the game auxiliary display 12 (Sb2). .

  Next, the error code stored in the register is checked, and it is determined whether or not the error code is an error code indicating a RAM abnormal error or an abnormal winning error (Sb3), indicating a RAM abnormal error or an abnormal winning error. In the case of an error code, after initialization 1 is performed to initialize all the storage areas in the storage area of the RAM 41c except the used stack area (Sb4), the process proceeds to a loop process in which no process is performed. To do.

  If it is determined in step Sb3 that the error code is not an error other than a RAM error or an abnormal winning error, it is determined whether an operation of the reset / setting switch 38 is detected (Sb5). If the operation of the reset / setting switch 38 is not detected, it is further determined whether or not the operation of the reset switch 23 is detected (Sb6). If the operation of the reset switch 23 is not detected, the process proceeds to step Sb5. Return. That is, the game waits in a state where the progress of the game is impossible until the operation of the reset / setting switch 38 or the reset switch 23 is detected.

  When the operation of the reset / setting switch 38 is detected in the step Sb5 or when the operation of the reset switch 23 is detected in the step Sb6, the error code stored in the register is cleared (Sb7 ), The display state of the game auxiliary display 12 is returned to the display state saved in the stack in the step Sb1 (Sb8), and the process returns to the original process.

  As described above, in the error processing, if the error processing is other than the RAM abnormal error and the abnormal winning error, the reset / setting switch 38 or the reset switch 23 is operated, so that the error processing is canceled. The error state is not canceled even if the reset / setting switch 38 or the reset switch 23 is operated in the case of error processing due to a RAM abnormality error or an abnormal winning error.

  Returning to FIG. 8, if it is determined in step Sa9 that the data for destructive diagnosis is normal, the data in the RAM 41c is normal, so the non-saved work, the unused area, and the unused stack area in the RAM 41c are initialized. After performing initialization 3 (Sa11), the destruction diagnosis data is cleared (Sa12). Next, it is determined whether any special role is won in the state before the power interruption (Sa13). If any special role is elected in the state before the power interruption, A power-on command indicating winning is set (Sa14), and the process proceeds to step Sa16. If no special role is won in the state before power interruption, a power-on command indicating non-winning special role is set. (Sa15), the process proceeds to step Sa16.

  In step Sa16, each register is restored to the state before power interruption, that is, stored in the stack, interrupt is permitted (Sa17), and the process executed last before power interruption is returned. In addition, when an interrupt is permitted in the step Sa17, the timer interrupt process is periodically executed. Accordingly, the power-on command set in the step Sa14 or Sa15 is sent to the sub-control unit 91. Sent.

  If the setting key switch 37 is in the ON state in the step of Sa6, after executing initialization 1 for initializing all the storage areas except the used stack area in the storage area of the RAM 41c (Sa18), The value stored in the set value work (0 at this time) is corrected to 1 (Sa19). Next, after a setting start command is set (Sa20), interruption is permitted (Sa21), and the setting change process shown in FIG. 10, ie, the setting change mode is entered (Sa22). When the interrupt is permitted in the step Sa21, the timer interrupt process is periodically executed, and accordingly, the setting start command set in the step Sa20 is transmitted to the sub-control unit 91. . After the setting change process in step Sa22 is completed, an initialization command is set (Sa23), and the process proceeds to the game process. The initialization command set in step Sa23 is transmitted to the sub-control unit 91 in the subsequent timer interrupt process.

  In the setting change process, as shown in FIG. 10, the set value stored in the set value work of the RAM 41c (the value of the set value work is corrected to 1 before shifting to the setting change process. Is read out (Sc1).

  After that, the operation waits for detection of the operation of the reset / setting switch 38 and the start switch 7 (Sc2, Sc3). When the operation of the reset / setting switch 38 is detected in the step of Sc2, the setting value read in the step of Sc1. 1 is added to (Sc4), and it is determined whether or not the set value after addition is 7, that is, whether or not the settable range is exceeded (Sc5). If the set value after addition is not 7, After returning to the detection waiting state for the operation of the reset / setting switch 38 and the start switch 7 in the steps Sc2 and Sc3 again, if the setting value after addition is 7 in the step Sc5, the setting value is corrected to 1 (Sc6). ), The process returns to the detection waiting state for the operation of the reset / setting switch 38 and the start switch 7 in the steps Sc2 and Sc3.

  When the operation of the start switch 7 is detected in the step of Sc3, the changed set value selected at that time is stored in the set value work of the RAM 41c and the set value is confirmed (Sc7). Wait until the setting key switch 37 is turned off (Sc8). If it is determined in step Sc8 that the setting key switch 37 is OFF, the flow returns to the flowchart of FIG. 8 and the game process is started.

  As described above, in the startup process, when the setting key switch 37 is not in the ON state, it is stored in the RAM 41c by determining whether or not the RAM parity is 0 and whether or not the destructive diagnosis data is normal. It is determined whether the stored data is normal. If the data in the RAM 41c is not normal, the process proceeds to error processing. In the error processing due to the RAM abnormal error, an error code indicating the RAM abnormal error is displayed on the game auxiliary display 12, and then the process proceeds to a loop process in which no processing is performed, so that the progress of the game is disabled. If the data in the RAM 41c is not normal, interrupts are not permitted. Therefore, once the process shifts to error processing due to a RAM error, the setting key switch 37 is activated and interrupts are permitted. Until it is interrupted, the interruption interruption process (main) is not performed even if the interruption occurs. That is, the RAM adjustment data is not calculated and stored so that the RAM parity is newly set to 0 in the power interruption interrupt process (main), and the destruction diagnosis data is not newly set. Even if the CPU 41a is restarted, the game cannot be restarted even if the CPU 41a is restarted, except when the setting key switch 37 is started in the ON state.

  Once the process shifts to error processing due to a RAM abnormality error, the setting key switch 37 is activated in the ON state, and after all the areas except the used stack area of the RAM 41c are initialized, a setting change process is performed. The game cannot be progressed until a new set value is selected and set by operating the reset / setting switch 38. In other words, in the state where the error processing due to the RAM abnormality error is started, the state in which the game cannot be progressed is canceled and the game is resumed on the condition that a new set value is selected and set by operating the reset / setting switch 38. It becomes possible to make it.

  FIG. 11 is a flowchart showing the control contents of the game process executed by the CPU 41a.

  In the game process, a BET process (Sd1), an internal lottery process (Sd2), a reel rotation process (Sd3), a winning determination process (Sd4), a payout process (Sd5), and a game end process (Sd6) are sequentially executed. When the end-time process ends, the process returns to the BET process again.

  In the BET process in the step of Sd1, the process waits in a state where the bet number can be set, sets a predetermined number of bets according to the gaming state, and executes a process of determining the bet number when the start switch 7 is operated. To do.

  In the internal lottery process in step Sd2, a random number for internal lottery is extracted simultaneously with the start of the game by the detection of the start switch 7 in step Sd1, and the winning of each above-described combination is permitted based on the extracted random number value. Process to determine whether or not. In this internal lottery process, a winning flag is set in the RAM 41c based on the respective lottery results.

  In the reel rotation process in the step of Sd3, the process of rotating each reel 2L, 2C, 2R and the operation of the corresponding reel 2L, 2C, 2R in response to the operation of the stop switch 8L, 8C, 8R detected by the player are detected. A process for stopping the rotation is executed. In addition, when a predetermined automatic stop time has elapsed from the start of rotation of the reel, the rotation of the reels 2L, 2C, and 2R is automatically stopped without waiting for detection of the operation of the stop switches 8L, 8C, and 8R. Execute the process.

  In the winning determination process in step Sd4, when it is determined in step Sd3 that the rotation of all the reels 2L, 2C, 2R has stopped, a winning is determined according to the display result derived for each reel 2L, 2C, 2R. A process of determining whether or not it has occurred is executed. In the winning determination process, an abnormal winning determination process is performed to determine whether or not an abnormal winning has occurred, such as winning a winning combination or winning a special combination and a general combination at the same time.

  In the payout process in step Sd5, when it is determined that a prize is generated in step Sd4, processing such as addition of credits and payout of medals is performed based on the number of payouts according to the win.

  In the game end process in the step of Sd6, a process for setting a gaming state in preparation for the next game is executed. Further, in the game end process, an RT process for performing control related to RT is also performed.

  FIG. 12 is a flowchart showing the control contents of the internal lottery process executed by the CPU 41a in step Sd2.

  In the internal lottery process of the present embodiment, first, a prescribed number that is a predetermined number of medals inserted in accordance with the game state of the game is read (Se1), and the process proceeds to Step Se2. The prescribed number is 3 in the normal gaming state and RT, and 1 in the regular bonus gaming state.

  In the step of Se2, it is determined whether or not the number of inserted medals, that is, the value of the BET counter is the specified number read in the step of Se1, and if the inserted number of medals is the specified number, the process proceeds to the step of Se3. If the input number is not the specified number, the process proceeds to Step Se4.

  In the step of Se3, it is determined whether or not the set value stored in the set value work of the RAM 41c is in the range of 1 to 6, that is, whether or not the set value stored in the set value work is an appropriate value. If the set value is in the range of 1 to 6, the process proceeds to Step Se5, and if not, the process proceeds to Step Se4.

  In the step of Se4, since it is determined that the data stored in the RAM 41c is not normal, an error code indicating a RAM abnormality is stored in the register, and the process proceeds to the error processing shown in FIG.

  In the step of Se5, a random number acquisition process for acquiring a random number used in the game is performed, and the process proceeds to the step of Se6. In the random number acquisition process, a sampling command is output to the sampling circuit 43, the random number generated by the random number generation circuit 42 is latched, and the latched random number value is input from the I / O port 41d and extracted. A predetermined logical operation is performed on the extracted random number, and the result is obtained as a random number.

  In the step of Se6, the state number (any one of 0 to 4) is stored in the RAM 41c according to the game state of the game, and the process proceeds to the step of Se7. In the step of Se7, in the gaming state indicated by the state number, the hand number to be drawn first is stored in the RAM 41c, and the process proceeds to the step of Se8. In the step of Se7, when the state number is 0 or 1, that is, when any special combination is not carried over in the normal gaming state or RT, the first combination number to be drawn (1 (big bonus (1)) ) And if the status number is 2 or 3, that is, if any special role is carried over in the normal gaming state or RT, 10 (replay) is set as the first role number to be drawn When the state number is 4, that is, in the case of a regular bonus, 11 (cherry) is first set as the winning number to be drawn.

  In the step of Se8, it is confirmed whether or not the number of the role to be drawn is 15, that is, whether or not the lottery of all the roles to be drawn has been completed. If the lottery of the combination is finished, the process proceeds to Step Se9. If not 15, the process proceeds to step Se10.

  In step Se9, the general combination storing work in which the general combination winning flag is stored in the RAM 41c is cleared, the internal lottery process is terminated, and the process returns to the flowchart shown in FIG.

  In the step of Se10, it is checked whether or not the common flag registered in the role-specific table is 1 in association with the processing target number, and if it is 1, the process proceeds to the step of Se11. Advances to step Se12.

  In step Se11, the address of the storage area for the number of determination values in the ROM 41b registered in the role-specific table in association with the role number to be processed is read. Then, the number of determination values stored at this address is acquired, and the process proceeds to Step Se13.

  In the step of Se12, first, the setting value stored in the RAM 41c is read, and further, the number of determination values of the ROM 41b registered in the role-specific table is stored in association with the processing target role number and the read setting value. Read the address of the area. Then, the number of judgment values stored at this address is acquired, and the process proceeds to Step Se13.

  In the step of Se13, the number of determination values acquired in the step of Se11 or Se12 is added to the random number value for internal lottery, and the result of the addition is set as a new random number value. It is determined whether an overflow has occurred when added to the random number value. The occurrence of an overflow indicates that the winning combination corresponding to the processing target winning number has been won. If an overflow occurs, the process proceeds to step Se16. If no overflow has occurred, the process proceeds to step Se15.

  In step Se15, 1 is added to the role number to be processed, and the process returns to step Se8.

  In the step of Se16, it is confirmed whether or not the combination number is 1 to 9, that is, a combination number indicating a special combination or a combination including a special combination. If the combination number is 1 to 9, the step of Se17 If the combination number is not 1 to 9, the process proceeds to Step Se18.

  In the step of Se17, a special combination winning flag corresponding to the combination number to be processed is set in the special combination storing work in which the special combination winning flag is stored in the RAM 41c. In the step of Se18, the general combination storing work of the RAM 41c. In addition, the winning flag of the general combination corresponding to the combination number to be processed is set, the internal lottery process is terminated, and the process returns to the flowchart shown in FIG. In the step Se18, when the combination numbers are 1 to 3, since the general combination is not won, the general combination storing work in the RAM 41c is cleared in this case.

  13 and 14 are flowcharts showing the control contents of the reel rotation process executed by the CPU 41a in the step Sd3.

  In the reel rotation process, first, it is determined whether or not a wait time (about 4.1 seconds in this embodiment) has elapsed since the reel rotation start time of the previous game (Sf1), and the wait time must have elapsed. If this happens, wait until the wait time has elapsed.

  If the wait time has elapsed in step Sf1, a new wait time is set (Sf2).

  Next, after setting the automatic stop time (Sf3), the reel motor is set to start rotating, and the reel starts rotating (Sf4). Then, the process proceeds to step Sf5 to determine whether or not an automatic stop flag indicating that automatic stop control is being performed is set in the RAM 41c. If the automatic stop flag is not set, the process proceeds to step Sf7 and the automatic stop flag is set. If YES, the process proceeds to step Sf6, and it is determined whether or not there is one spinning reel.

  If the number of rotating reels is not one in step Sf6, that is, if two or more reels are still rotating, the process proceeds to step Sf7, and if one reel is rotating, the process proceeds to step Sf8.

  In step Sf7, the table creation data is identified with reference to the table index, and the game status of the game, the winning combination status of the game, and the stop status of other reels are handled based on the identified table creation data. A stop control table is created for each rotating reel, and the process proceeds to step Sf9.

  In step Sf8, a non-winning position table indicating whether or not each area number is a non-winning position is created based on the stop position of the stopped reel, and the process proceeds to step Sf9.

  In step Sf9, a stop preparation completion code indicating completion of stop preparation is set, and the process further proceeds to step Sf10. In the timer interruption process (main), which will be described later, the process of rotating the reel at a constant speed is performed. Wait until it is detected.

  If it is determined in step Sf10 that the constant rotation of the reel has been detected, the process proceeds to step Sf11, and it is determined whether or not an automatic stop flag is set. If the automatic stop flag is not set, step Sf12 is performed. Then, the detection of the stop switches 8L, 8C, 8R is validated, and the process proceeds to step Sf13. On the other hand, if the automatic stop flag is set in step Sf11, the process proceeds to step Sf13 without enabling the detection of the stop switches 8L, 8C, 8R.

  In step Sf13, it is determined whether or not an automatic stop flag is set. If the automatic stop flag is set, the process proceeds to step Sf14 to perform automatic stop control, and the automatic stop flag must be set. If so, the process proceeds to step Sf20.

  In step Sf14, it is determined whether or not there is one spinning reel. If there is one spinning reel, the process proceeds to step Sf33. If there is not one spinning reel, that is, two or more reels. If the right reel is rotating, it is determined whether or not the right reel is rotating. If the right reel is not rotating, the process proceeds to Sf16 to determine whether or not the middle reel is rotating. judge.

  If the right reel is rotating in the step of Sf15, the process proceeds to the step of Sf18, and the number of steps from the reel reference position at that time of the reel motor corresponding to the right reel (the number of steps as the stop operation position) is acquired. After setting the work corresponding to the right reel, the process proceeds to step Sf33 and waits until the rotation of the right reel stops.

  If the middle reel is rotating in the step of Sf16, the process proceeds to the step of Sf19, and the number of steps from the reel reference position at that time of the reel motor corresponding to the middle reel (the number of steps as the stop operation position) is acquired. After setting the work corresponding to the middle reel, the process proceeds to step Sf33 and waits until the rotation of the middle reel stops.

  If the middle reel is not rotating in step Sf16, that is, if the left reel is rotating, the process proceeds to step Sf17, and the number of steps from the reel reference position at that time of the reel motor corresponding to the left reel (stop operation position). Is obtained and set to the work corresponding to the left reel, the process proceeds to step Sf33 and waits until the rotation of the left reel stops.

  Then, when the rotation of the reels stops in the step of Sf33, the process proceeds to the step of Sf34, and it is determined whether or not all the reels are stopped. If all the reels are not stopped, the process proceeds to the step of Sf35, and It is determined whether or not the cherry has stopped on any of the winning lines. If the cherry has not stopped on any of the winning lines on the left reel, the process returns to step Sf5, and the cherry on any of the winning lines on the left reel. If the cherry has stopped, the process proceeds to step Sf36, a cherry winning flag indicating that the cherry has won before the automatic stop is set in the RAM 41c, and the process returns to step Sf5.

  If all the reels are stopped in step Sf34, the reel rotation process is terminated and the process returns to the flowchart of FIG.

  In step Sf20, it is determined whether or not the automatic stop time set in step Sf3 has elapsed. If the automatic stop time has elapsed, the process proceeds to step Sf21. If the automatic stop time has not elapsed, the process proceeds to Sf23. Proceed to step.

  In step Sf21, an automatic stop flag is set in the RAM 41c, the process proceeds to step Sf22, the detection of the operation of the stop switches 8L, 8C, and 8R is invalidated, and the process returns to step Sf13.

  In step Sf23, it is determined whether or not any of the stop switches 8L, 8C, and 8R is detected. If no stop switch is detected, the process proceeds to step Sf24. If the operation of the stop switch is detected, the process proceeds to step Sf31.

  In step Sf24, it is determined whether or not a reel rotation error (error determined when the reel reference position is not detected by the reel sensor 33 for a certain period or longer) has occurred. If no reel rotation error has occurred, Sf25 is determined. If a reel rotation error has occurred, the process proceeds to step Sf29.

  In step Sf25, it is determined whether or not an insertion error (an error determined when the insertion of a medal is detected in a period other than the period during which the insertion of a medal is permitted) has occurred. If the error has occurred, the process proceeds to Sf27.

  In step Sf26, it is determined whether or not a payout error (error determined when medal payout is detected outside the period during which medal payout is permitted) has occurred, and no payout error has occurred. If the payout error has occurred, the process proceeds to Sf27.

  In step Sf27, an error code indicating an insertion / withdrawal error during reel rotation is set in the register, the process proceeds to step Sf28, and the process proceeds to error processing shown in FIG. When the error is released, the process returns to step Sf13 again.

  In step Sf29, an error code indicating a reel rotation error is set in the register, the process proceeds to step Sf30, and the process proceeds to error processing shown in FIG. Along with this, the rotation of the reels is also temporarily stopped. When the error is released, the process returns to the step Sf3 again, and the reel rotation is resumed.

  In step Sf31, the detection of the operation of the stop switches 8L, 8C, 8R is invalidated and the process proceeds to step Sf32. The step from the reel reference position at that time of the reel motor corresponding to the stop switch detected in step Sf23 is performed. After obtaining the number (the number of steps at the stop operation position) and setting the work corresponding to the stop reel, the process proceeds to step Sf33 and waits until the rotation of the reel corresponding to the stop operation stops.

  When the rotation of the corresponding reel is stopped in the step of Sf33, the process proceeds to the step of Sf34 described above, and it is determined whether or not all the reels are stopped. If all the reels are not stopped, the process proceeds to the step of Sf35. Proceed to determine whether the cherry is stopped on the left reel. If the cherry is not stopped on the left reel, the process returns to step Sf5, and if the cherry is stopped on the left reel, the cherry winning flag is set. Thereafter, returning to the step of Sf5, if all the reels are stopped in the step of Sf34, the reel rotation processing is terminated and the process returns to the flowchart of FIG.

  FIG. 15 is a flowchart showing the control contents of the abnormal winning determination process executed by the CPU 41a during the winning determination process of step Sd4.

  In the abnormal winning determination, first, it is determined whether or not the automatic stop flag is set (Sg1). If the automatic stop flag is not set, the process proceeds to step Sg5. If the automatic stop flag is set in the step of Sg1, the process proceeds to the step of Sg2, and the value of the winning symbol flag is 0000H, that is, all the values of the 0th to 15th bits of the winning symbol flag are 0. If the value of the winning symbol flag is 0000H, the process proceeds to step Sg5. If the value of the winning symbol flag is not 0000H, the process proceeds to step Sg3.

  In the step of Sg3, the value of the winning symbol flag is 8000H, that is, the value of the 15th bit corresponding to cherry out of the 0th to 15th bits of the winning symbol flag is 1 and the value of the other bits is 0. If the value of the winning symbol flag is not 8000H, the process proceeds to step Sg12. If the value of the winning symbol flag is 8000H, the process proceeds to step Sg4.

  In step Sg4, it is determined whether there is a cherry stopped flag, that is, whether the cherry has stopped before shifting to automatic stop. If there is no cherry stopped flag, the process proceeds to step Sg12, where the cherry stopped flag is set. If there is, the process proceeds to step Sg5.

  In the step of Sg5, the logical sum (OR) of the lower 8 bits of the winning symbol flag is calculated, that is, logical OR operation is performed on each bit of the lower byte (0th bit to 7th bit), and the process proceeds to the step of Sg6. The logical sum (OR) of the upper 8 bits of the symbol flag is calculated, that is, each bit of the upper bytes (8th to 15th bits) of the winning symbol flag is ORed, and the lower 8 bits of the winning symbol flag in the step of Sg5 And the logical sum of the upper 8 bits of the winning symbol flag in the Sg6 step (Sg7), and whether the value calculated in the Sg7 step is not 0 Is determined (Sg8).

  In the step of Sg8, if the logical product of the result of the logical sum of the upper 8 bits and the lower 8 bits of the winning symbol flag in the step of Sg7 is not 0, the process proceeds to the step of Sg12. , Iwin_fIag (internal winning flag storage work) value is inverted for all bits (Sg9), and a value obtained by inverting all bits of iwin_fIag (abnormal winning determination flag) and the winning symbol flag are ANDed (Sg10). , Go to Sg11 step.

  In the step of Sg11, it is determined whether or not the logical product of the value (abnormal winning determination flag) obtained by inverting all the bits of iwin_fIag in the step of Sg10 and the winning symbol flag is not 0. If it is 0, the process proceeds to step Sg12.

  In step Sg12, an error code indicating an abnormal winning is set, and the process proceeds to error processing.

  FIGS. 16 and 17 are flowcharts showing the control contents of the timer interrupt process (main) executed by the CPU 41a in response to the occurrence of the interrupt 3, that is, interrupting the start process or the game process at intervals of 0.56 ms. .

  In the timer interrupt process (main), interrupts are first prohibited (Si1). That is, the execution of another interrupt process during the execution of the timer interrupt process (main) is prohibited. Then, the register in use is saved in the stack area (Si2).

  Next, the branch counter for identifying the timer interrupt to be executed in the timer interrupt process (main) is advanced by 1 from the four types of timer interrupts 1 to 4 (Si3). In the step of Si3, 1 is added when the branch counter value is 0 to 2, and is updated to 0 when the counter value is 3. That is, the branch counter value loops in the order of 0 → 1 → 2 → 3 → 0... Each time the timer interrupt process (main) is executed.

  Next, the branch counter value is referred to determine whether it is 2 or 3, that is, timer interrupt 3 or timer interrupt 4 (Si4). If it is not timer interrupt 3 or timer interrupt 4, that is, timer interrupt In the case of 1 or timer interrupt 2, it is checked whether the reel motors 32L, 32C, 32R are started or whether they are rotating at a constant speed, and whether the reel motors 32L, 32C, 32R are started or are rotating at a constant speed. For example, the motor phase signal output process is executed to output the phase signal data changed in the Si8 motor step process described later and the phase signal data changed in the Si23 final stop process described later (Si5).

  Next, it is determined whether or not it is 1 (ie, timer interrupt 2) by referring to the minute counter value (Si6). If it is not timer interrupt 2 (ie, timer interrupt 1), the reel motor Reel start processing (Si7) for controlling the step time interval when starting 32L, 32C, 32R, motor step processing (Si8) for changing phase signal data of the reel motors 32L, 32C, 32R, reel motors 32L, 32C After the stop of 32R, the motor phase signal standby processing (Si9) for changing the phase signal to one-phase excitation after a predetermined time has been sequentially executed, and then the register saved in the stack area in Si2 is restored (Si20). The interrupt prohibited in the step is permitted (Si21), and the process returns to the state before the interrupt.

  Further, in the case of timer interrupt 2 in the step of Si6, LED dynamic display processing (Si10) for dynamically lighting various indicators, output processing of control signals and the like for outputting data such as lighting signals of various LEDs to an output port (Si11), random number update processing for updating various software random numbers (Si12), time counter update processing for updating various time counters (Si13), command transmission for transmitting commands stored in the command queue to the effect control board 90 After executing the process (Si14) and the external output signal update process (Si15) for updating the external output signal in sequence, the register saved in the stack area in Si2 is restored (Si20), and the interrupts prohibited in the Si1 step are permitted. (Si21), and the process returns to the state before the interruption.

  If it is timer interrupt 3 or timer interrupt 4 in the Si4 step, it is further determined by referring to the counter value for wake-up 3 whether it is 3, ie, timer interrupt 4 (Si16). If it is not interrupt 4, that is, timer interrupt 3, port input processing (Si17) for inputting detection data of various switches from the input port, passing the origin of the rotating reels 2L, 2C, 2R (reel reference) (Passing position) is detected, the occurrence of a reel rotation error is detected, whether stop preparation is completed (stop preparation completion code is set), stop preparation is complete, and If it is rotating at high speed, the origin passing process (Si18) that permits the operation of the stop switch corresponding to the reel that is rotating, based on detection signals of various switches After sequentially executing the switch input determination process (Si19) for determining whether or not the seed switch satisfies the detection condition, the register saved in the stack area in Si2 is restored (Si20), and the interrupts prohibited in the Si1 step Is permitted (Si21) and the process returns to the state before the interruption.

  If the timer interrupt is 4 in the step of Si16, when the stop operation position is stored in the work on the stop reel in accordance with detection of the stop switches 8L, 8C, 8R or automatic stop control (other than final stop). The stop position is determined from the stop operation position stored in the work of the stop reel, the number of steps after which the stop should be calculated is calculated, and at the final stop of the automatic stop control, the non-winning position table is referred to, When the number of steps reaches the non-winning position, the stop switch process (Si22) for calculating the number of steps after which the stop should be performed, the number of steps until the stop calculated by the stop switch process, and the timing for stopping Stop process (Si23) to start braking by two-phase excitation when it becomes, and three phases after a certain time from the start of braking in the stop process After sequentially executing the final stop process (Si24) to be magnetized, the register saved in the stack area in Si2 is restored (Si20), the interrupt prohibited in the Si1 step is permitted (Si21), and the pre-interrupt Return to processing.

  FIG. 18 is a flowchart showing the control contents of the stop switch process executed by the CPU 41a in the timer interrupt 4 of the timer interrupt process (main) described above.

  In the stop switch process, first, it is determined whether or not the automatic stop is performed based on whether or not the automatic stop flag is set in the RAM 41c (Sj1). If not the automatic stop, the process proceeds to step Sj7. Proceed to step Sj2.

  In step Sj2, it is determined whether or not it is the final stop reel, that is, whether or not two reels have already been stopped. If it is not the final stop reel, the process proceeds to step Sj7. It is determined whether or not (Sj3).

  If the stop preparation is not completed in step Sj3, the stop switch process is terminated and the process returns to the flowchart of FIG. On the other hand, if the stop preparation is completed in the step Sj3, the non-winning position flag corresponding to the area number including the current step number in the non-winning position table is referred to (Sj4). It is determined whether or not any combination is stopped on the winning line when it is stopped immediately (Sj5).

  If the non-winning position flag is 0 in step Sj5, the stop switch process is terminated and the process returns to the flowchart of FIG. On the other hand, if the non-winning position flag is 1 in step Sj5, the number of steps required to reach the stop position that can be stopped at the earliest stage at that time is calculated, and the calculated number of steps is set (Sj6 ), The stop switch process is terminated, and the process returns to the flowchart of FIG.

  In steps Sj7 and Sj8, for all reels in the order of left, middle, and right, whether or not a stop operation position has been set for the work on the corresponding reel, that is, a stop operation has been detected or stopped by automatic stop If the stop operation has not been detected for all the reels or if stop has not been instructed, the stop switch process is terminated and the process returns to the flowchart of FIG.

  If any reel stop operation is detected in step Sj7 or if a reel stop instruction is issued, the process proceeds to step Sj9, and the stop control table corresponding to the reel is referred to. From the area number including the step number of the stop operation position set for the work corresponding to the stop reel, the area number serving as the stop position is specified, and the process proceeds to step Sj10, from the number of steps from the current reel reference position. After calculating the number of steps required until the stop position specified in step Sj9 and setting the calculated number of steps, the stop switch process is terminated and the process returns to the flowchart of FIG.

  FIG. 19 shows a power interruption interrupt process (main) executed by the CPU 41a in response to the occurrence of an interrupt 2, that is, when a voltage drop signal from the power interruption detection circuit 48 is input, interrupting the execution process or the game process. It is a flowchart which shows the control content of.

  In the power interruption interruption process (main), first, interruption is prohibited (Sk1). That is, other interrupt processing is prohibited from being executed at the start of the power interruption interrupt processing (main). Next, all registers that may be in use are saved in the stack area (Sk2). Note that the values of the I register and IY register described above are used, but are not saved here because the same fixed value is always set with the initialization at the time of startup.

  Next, the detection data of the voltage drop signal is acquired from the input port, and it is determined whether or not the voltage drop signal is input (Sk3). At this time, if the voltage drop signal is not input, the register saved in the stack area in Sk2 is restored (Sk4), the interrupt prohibited in the Sk1 step is permitted (Sk5), and the process before the interrupt is performed. Return.

  If a voltage drop signal is input in step Sk3, the destruction diagnosis data (5A (H) in this embodiment) is set (Sk6), and all output ports are initialized (Sk7). . Next, the RAM parity adjustment data is calculated and set so that the exclusive OR of all the storage areas (including the unused area and the unused stack area) of the RAM 41c becomes 0 (Sk8), and access to the RAM 41c is performed. It is prohibited (Sk9).

  Then, except for the determination as to whether or not the voltage drop signal is input (Sk10, where Sk10 is the same process as Sk3), the process enters a loop process in which no process is performed. That is, when the voltage decreases as it is, the operation is stopped internally. Therefore, the CPU 41a reliably stops operation when the power is interrupted. Further, in this loop processing, when the voltage recovers and the voltage drop signal is not input, the above-described startup processing is executed, and if the RAM parity is 0 and the destructive diagnosis data is normal, the original processing is performed. It will return to.

  In this embodiment, after the access to the RAM 41c is prohibited, the output state of the voltage drop signal is monitored, and when the voltage drop signal is not input, it is determined that the voltage is restored, and the process proceeds to the startup process. However, no processing is performed in the loop processing, and the voltage is recovered while the loop processing is being performed, and the process proceeds to the start-up processing based on the input of the reset signal from the reset circuit 49. You may make it do.

  Next, various control contents executed by the CPU 91a of the sub-control unit 91 mounted on the effect control board 90 will be described below based on the flowcharts of FIGS.

  When a reset signal is input from the reset circuit 95 to the sub control unit 91, the CPU 91a performs a start process (sub) illustrated in FIG.

  In the startup process (sub), the built-in device, peripheral IC, interrupt mode, stack pointer, etc. are initialized (Sr1), and then access to the RAM 91c is permitted (Sr2). Then, the RAM parity of all the storage areas of the RAM 91c is calculated (Sr3), and it is determined whether or not the RAM parity is 0 (Sr4).

  If the data in the RAM 91c is normal, the RAM parity should be 0. If the RAM parity is 0 in the step Sr4, the data stored in the RAM 91c is normal, and the process proceeds to the step Sr5. The production state before power interruption is restored. In step Sr5, after setting the last control pattern executed before power interruption, only command reception interrupt processing is permitted (Sr6), and the process proceeds to step Ss7.

  If the RAM parity is not 0 in step Sr4, the data stored in the RAM 91c is not normal. After the RAM 91c is initialized (Sr13), the standby pattern is set as a control pattern (Sr14). Only command reception interrupt processing is permitted (Sr6), and the process proceeds to step Sr7.

  In step Sr7, it is determined whether an initialization command has been received. If no initialization command has been received, the process proceeds to step Sr8, in which it is determined whether a power-on command has been received. If the initialization command is received, the RAM 91c is initialized (Sr15), the standby pattern is set as the control pattern (Sr16), and the process proceeds to Sr11.

  In step Sr8, if the power-on command is not received, the process returns to step Sr7 again. If the power-on command is received, the process proceeds to step Sr9.

  In step Sr9, based on the power-on command received in step Sr8, it is determined whether or not a special role is elected in the state before power interruption (Sr13), and the special role is elected in the state before power interruption. If the special role notification pattern for notifying the winning of the special role is set as the control pattern (Sr10), the liquid crystal display 51, the effect effect LED 52, the speakers 53 and 54, the reels are set according to the set control pattern. An effect control process for controlling various effect devices such as the LED 55 is executed (Sr11), all interruptions are permitted (Sr12), and the process proceeds to a loop process.

  Further, in the step Sr9, when the special role is not elected in the state before the power interruption, the liquid crystal display according to the control pattern set in the step Sr5, that is, the control pattern set before the power interruption. 51, an effect control process for controlling various effect devices such as the effect effect LED 52, the speakers 53 and 54, and the reel LED 55 is executed (Sr11), all interruptions are permitted (Sr11), and the process proceeds to the loop process.

  FIG. 21 is a flowchart showing the control contents of the timer interrupt process (sub) executed by the CPU 91a at intervals of 1.12 ms based on the count of the internal clock.

  In the timer interrupt process (sub), first, it is determined whether or not a command is stored in the buffer (Ss1). If the command is not stored in the buffer, the process proceeds to step Ss7. If the command is stored in the buffer, the command is acquired from the buffer (Ss2), and the process proceeds to step Ss3.

  In the step of Ss3, display control processing for performing display control of the fluctuation region of the liquid crystal display 51 is executed according to the received command, and the process proceeds to the step of Ss4.

  In the step of Ss4, when the received command is an internal winning command, the presentation table stored in the ROM 91b is referred to, and the result of the internal lottery indicated by the internal winning command corresponds to the display pattern selected in the display control process. The effect pattern is selected at the selected rate, and an effect pattern selection process is performed in which the selected effect pattern is set in the RAM 91c as the effect pattern of the game, and the process proceeds to step Ss5.

  In step Ss5, processing corresponding to the received command is performed, and the control pattern table stored in the ROM 91b is referred to, and the effect pattern set in the RAM 91c and the control registered corresponding to the received command are stored. A control pattern setting process for reading the pattern and setting it in the RAM 91c is executed, and the process proceeds to step Ss6.

  In step Ss6, an effect control process for controlling various effect devices such as the liquid crystal display 51, effect LED 52, and speakers 53 and 54 is executed according to the control pattern set in step Ss7, and the process proceeds to step Ss7. .

  In the step of Ss7, date / time information (date, time) is acquired from the clock device 97. When the acquired date / time information is reset, a date / time information setting screen (not shown) on which date / time information can be set. Is displayed on the liquid crystal display 51, and when an item on the date / time information setting screen is selected from among various menu items displayed on the menu screen, a process corresponding to the selected item is displayed. (Date and time information setting process) is performed, and the process proceeds to step Ss8. That is, when the date / time information acquired from the clock device 97 is reset when the sub-control unit 91 is activated, a menu screen capable of selecting the date / time information setting screen is reliably displayed, and the date / time at that time is displayed. When information is not set, the menu screen cannot be cleared as described above, and a message for prompting the date and time setting is displayed, so that time management can be performed thoroughly.

  In step Ss8, the door open history information stored in the RAM (not shown) of the door open detection IC 98a is requested to be acquired, and the door open history information stored in the RAM is updated at that time. In this case, all door opening history information stored in the RAM is acquired, door opening processing for storing the acquired door opening history information in the RAM 91c is executed, and the process proceeds to step Ss9.

  In step Ss9, when the sub control unit 91 is activated, a menu screen is displayed that allows selection of display of various history information such as door opening history and setting change history based on door opening history information stored in the RAM 91c. At the same time, when any one of the various menu items displayed on the menu screen is selected, a menu screen display process corresponding to the selected item is performed, and the process proceeds to step Ss10.

  In step Ss10, after updating the values of various counters such as a random number counter in the RAM 91c, the process proceeds to step Ss11, where it is confirmed whether the content of data backed up in the RAM 91c at the time of startup is normal. The RAM parity adjustment data is calculated and set so that the exclusive OR of all the storage areas of the RAM 91c becomes 0 (Ss11) so that the timer interrupt process (sub) is completed.

  That is, the CPU 91a does not set the RAM parity adjustment data when the power interruption is detected like the CPU 41a of the main control unit 41, but the RAM parity adjustment data for each timer interrupt process (sub) that is periodically executed. Even if the power is cut off, it is possible to determine whether or not the content of the data backed up in the RAM 91c at the time of recovery is normal.

  As described above, in the slot machine 1 of this embodiment, whether or not the value read from the set value work is in the range of 1 to 6, that is, whether or not the set value used for the internal lottery is in the proper range. If it is determined for each game and the value read from the set value work is not a value in the range of 1 to 6, it is controlled to an error state due to a RAM abnormality error, and the progress of the game is disabled. In this embodiment, the value stored in the set value work, that is, the range of the set value that can be selected by the setting change process is a value of 1 to 6, and thus the value stored in the set value work is in the range of 1 to 6. If the value is not, the progress of the game is disabled.

  Further, a process for determining whether or not the set bet number is a bet number according to the gaming state is executed for each game, and the set bet number is not the bet number according to the game state. Control of the error state due to the RAM abnormal error disables the progress of the game. In this embodiment, the number of bets corresponding to each gaming state is determined, but if the game is played with a bet number different from the bet number, is the data stored in the RAM 41c broken? Or, since there is a possibility that an unauthorized program is operating, even if the set bet number is not the bet number according to the game state, the progress of the game is disabled.

  Then, once controlled to an error state due to a RAM abnormality error, the game cannot be progressed unless the setting change mode is entered and a setting value is newly selected and set based on the setting changing operation. Is not released. In other words, if the set value is not appropriate due to garbled data or illegal program operation, or if the set bet number is not the bet number according to the gaming state, the set value automatically set by the slot machine The game is executed based on the setting value selected and set based on the setting change operation (generally, since the setting change operation is performed by an employee of the amusement store, the setting value selected by the amusement store side). Since it is guaranteed that the game will be played, the fairness of the game can be improved.

  Further, in this embodiment, when an abnormality occurs in the data stored in the RAM 41c, the error state due to the RAM abnormality error is controlled, the progress of the game is disabled, and the error state once caused by the RAM abnormality error. If it is controlled, the state in which the progress of the game is disabled will not be released unless the setting change mode is entered and the setting value is newly selected and set based on the setting changing operation. That is, even if an abnormality occurs in the data stored in the RAM 41c, it is not the setting value automatically set by the slot machine, but the setting value selected and set based on the setting change operation (generally, the setting change Since the operation is performed by an employee of the amusement store, it is ensured that the game is performed based on the setting value selected by the amusement store side), so that the fairness of the game can be achieved.

  Further, the data stored in the RAM 41c is abnormal in most cases when the control cannot be continued due to a malfunction such as a power failure or the CPU 41a running out of control. For this reason, in this embodiment, since it is determined whether or not the data is normal only when the CPU 41a is activated after recovering from these states, it is determined whether or not the data stored in the RAM 41c is normal. The determination can be made only in a situation where there is a high possibility that an abnormality has occurred in the data. That is, in a situation where there is a low possibility that an abnormality has occurred in the data, it is not necessary to perform the determination, and the load on the CPU 41a can be reduced.

  In this embodiment, the RAM parity adjustment data is calculated and stored so that the RAM parity based on all the data in the RAM 41c in the power interruption processing (main), that is, the result of the exclusive OR operation is 0. In addition, since it is determined whether or not the data in the RAM 41c is normal by determining whether or not the RAM parity calculated based on the data stored in all areas in the RAM 41c at the time of recovery is 0. This determination can be performed accurately and simply.

  Further, in addition to the RAM parity adjustment data, the destructive diagnosis data whose bit value is not 1 is stored in the RAM 41c in the power interruption processing (main), and the RAM parity is 0 at the time of restoration. Even in such a case, it is further determined whether or not the destruction diagnosis data is normally stored. The data in the RAM 41c is initialized during the power failure, and the state before the power failure cannot actually be restored. Nevertheless, since all the data in the RAM 41c is 0, it is not determined to be normal.

  In particular, in this embodiment, when the connection between the connectors between the game control board 40 and the inserted medal sensor 31 is released even at one place, the backup data held in the RAM 41c of the main control unit 41 is lost. As a result, the destruction diagnosis data is cleared to 00H, so that when started in this state, the CPU 41a can reliably determine a RAM abnormality error and disable the progress of the game.

  In this embodiment, the CPU 41a performs an abnormal winning determination that determines whether or not a combination that is not permitted in the game is on the winning line when all the reels are stopped.

  In the abnormal winning judgment, if the roles are arranged in spite of the automatic stop (excluding cherries stopped before shifting to the automatic stop control), if the winning combination is found in the internal lottery, the special role and the general role It is determined that there is an abnormal prize when the two are arranged at the same time.

  When it is determined that the winning is abnormal, that is, when a winning combination that is not permitted in the game is won, the game is controlled to be in an error state due to an abnormal winning error and the progress of the game is disabled.

  As described above, in this embodiment, when the winning combination is achieved despite the automatic stop (excluding cherries stopped before shifting to the automatic stop control), that is, despite the automatic stop, it malfunctions due to some abnormality and wins. If this happens, the progress of the game will be disabled. Therefore, even if a prize that should not be won is generated, it will not be processed as a normal prize and the fairness of the game will be improved. It will not be damaged.

  In addition, when a combination that has not been won in the internal lottery or when a special role and a general role are won at the same time, that is, when a non-winning role is won or when a special role and a general role are won simultaneously The data may be destroyed or an abnormal program may be running. In such a case, the progress of the game will be disabled, and the fairness of the game will be impaired. There is no.

  Further, in this embodiment, once an error state due to an abnormal winning error is controlled, the game progresses unless the setting change mode is entered and a setting value is newly selected and set based on the setting changing operation. The disabled state is not released. In other words, when an unacceptable winning combination wins due to garbled data or abnormal program operation, it is not the setting value automatically set by the slot machine, but the setting selected and set based on the setting change operation Since it is ensured that the game is played based on the value (generally, the setting change operation is performed by an employee of the game shop, which is the set value selected by the game shop), the game is fair. be able to.

  Further, when the CPU 41a determines whether or not a winning combination that has not been won in the internal lottery has been won, if the value of the bit assigned to each type of winning combination is 0, the winning combination is won. If the value of the abnormal winning determination flag indicating that the winning combination is not won when it is 1 and the value of the bit assigned to each type of winning is 1, the fact that the winning combination has been won And a winning symbol flag indicating that the winning combination has not been won when it is 1, and indicates whether the calculation result is 0, that is, whether the calculation result is 0 or not. It is possible to determine whether or not an abnormal winning has occurred by simply referring to the value of the zero flag of the F register. Since it is not necessary to confirm It can be processed simplified when it is determined whether the prize.

  Further, in this embodiment, when the value of the bit assigned to each type of combination is 1, it indicates that the combination is won, and when it is 0, the combination is not selected. The internal winning flag shown is set in the internal winning flag storing work (iwin_fIag) assigned to the RAM 41c, and an operation for inverting 1 and 0 of each bit of the winning flag is performed to create an abnormal winning determination flag. It has become. That is, the abnormal winning determination flag can be easily created using the winning flag.

  In the slot machine of the present embodiment, if the player detects the operation of the stop switches 8L, 8C, 8R effectively after the reel starts rotating and before the predetermined automatic stop time has elapsed, The display result is derived to the corresponding reel in accordance with the setting status of the item and the timing of the stop operation. In other words, winning is generated not only by setting the winning flag but also by the player's technical intervention such as operation of the stop switches 8L, 8C, and 8R. Therefore, it is possible to prevent the winning from being generated only by chance factors. Security of sex will be secured.

  On the other hand, if a predetermined automatic stop time has elapsed after the reel starts rotating, if the reel is still rotating, automatic stop control is performed to automatically stop the rotating reel. That is, the time required for one game is not infinite, and even if the player is playing a game, a substantially sufficient operation rate cannot be obtained.

  In this embodiment, when a predetermined automatic stop time has elapsed after the start of reel rotation, if the reel is still rotating, automatic stop control is performed to automatically stop the rotating reel. However, the starting point for measuring the automatic stop time is not limited to the start of reel rotation. When the start switch 7 is operated, the reel rotates at a constant speed, and the stop switches 8L, 8C, 8R. The operation may be performed when the operation of the stop switches 8L, 8C, 8R disabled by the stop operation is enabled again, or when the stop operation is performed last.

  In addition, when each reel is stopped by the automatic stop control, even if the winning flag of any combination is set, the display mode of losing is always derived for each reel. For this reason, it is possible to prevent the winning display mode from being derived only by the contingency element, and to ensure the suppression of shooting characteristics.

  In addition, in the automatic stop control, except for the reel that stops at the end, refer to the stop control table of the corresponding reel as in the case of the stop operation, and respond based on the number of sliding frames in the referred stop control table. While the reels 2L, 2C, and 2R are controlled to stop rotating, the reels that are stopped at the end do not have any role on any winning line in the drawing range of up to 4 symbols, that is, in the range of 5 frames. The number of sliding symbols is specified, and control is performed to stop based on the smallest number of sliding symbols. In other words, except for the reel that stops at the end, control is performed according to the setting status of the winning flag regardless of whether stop operation is performed or automatic stop control. However, the control is performed so that the winning combination is not arranged on any winning line. For this reason, a function to perform automatic stop control is added because it is sufficient to perform control to stop the reels in a common process regardless of whether the stop operation is performed or automatic stop control is performed except for the reel to be stopped last. In addition, even if a function that always loses during automatic stop is added, the stop control of the reel is not complicated.

  In addition, for the final stop reel, for every area number, if the stop position corresponding to each area number is immediately stopped, whether or not any of the roles are non-winning positions that are not aligned on the winning line is determined. A non-winning position table is created, and the non-winning position table is referenced at regular intervals (about 2 ms) shorter than the time varying by one frame, and the area number to which the number of steps from the current reference position belongs is not winning Stop position that can be stopped at the earliest stage (a range of less than one frame) when it is determined that the area number to which the current step number belongs is a non-winning position by repeatedly performing the process of determining whether or not it is a position That is, the reel is controlled to stop at the position where the symbol corresponding to the area number stops at the lower stage, and when it is determined that the rotating reel is in the non-winning position, it slides one frame or more. Because it is possible to stop the display result that does not become a prize simply by stopping immediately, all the symbols within the drawing range every time the symbol moves one frame after the automatic stop time has elapsed, as before. Since there is no need to search for a non-winning position from among the above, even if a function for making sure to lose at the time of automatic stop is added in addition to the function of performing automatic stop control, the stop control of the reel is not complicated accordingly.

  After the shift to automatic stop control, the final stop reel may be controlled to stop immediately without slipping more than one frame when it is determined that the final stop reel is in the non-winning position. Since it is possible to perform stop control with a common program regardless of the number of steps at which the stop is started, the configuration of the control program associated with the automatic stop control can be simplified.

  In this embodiment, the non-winning position table is displayed when the two reels except the last reel are stopped after the shift to the automatic stop control, or when the two reels are stopped and the shift is made to the automatic stop control. The current number of steps is created by performing a process of determining whether or not the area number to which the number of steps from the current reference position belongs is a non-winning position with reference to the non-winning position table at a certain interval thereafter Is preferably a non-winning position, and it is preferable that the process of determining whether the area number to which the number of steps from the current reference position belongs is a non-winning position can be performed in a short time, After transition to automatic stop control without creating a non-winning position table, when the two reels except the last reel stop or when the two reels stop and then shift to automatic stop control Based on the stop position of the reels that have been stopped at regular intervals, it is determined whether or not it is a non-winning position when it is stopped immediately with less than one frame at the current number of steps. Control may be performed to stop the reel at a stop position at which it can be stopped at the earliest stage (a range of less than one frame) at the time when it is determined.

  Further, in this embodiment, the stop control according to the winning flag is based on the stop control table according to the winning flag, but other control methods (for example, those based on the control method) described later may be applied. Well, even when other control methods are applied in this way, control is performed according to the setting status of the winning flag, regardless of whether the stop operation is performed or automatic stop control, except for the reel that stops at the end. In the case of the automatic stop control, the same effect as described above can be obtained as long as the control is performed so that only the reel to be stopped last is not aligned on any winning line.

  Further, in this embodiment, when a stop operation is performed, the corresponding reel stop control table for all reels, i.e., referring to data in which the stop position can be specified in advance with respect to the stop operation position, Based on the number of sliding frames in the referred stop control table, control is performed to stop the rotation of the corresponding reels 2L, 2C, 2R, that is, control by the table system. In automatic stop control, the reels that are stopped last are stopped. As in the case where the operation is performed, a control for stopping the rotation of the corresponding reels 2L, 2C, 2R based on the number of sliding frames in the referred stop control table with reference to the stop control table of the corresponding reel, that is, a table For reels that are controlled by the system and stop last, after the transition to automatic stop, when other reels stop, or other A non-winning position table is created when the reels stop and then the automatic stop is started, and the area number to which the number of steps from the current reference position belongs is a non-winning position with reference to the non-winning position table. When the determination is made, the reel is stopped. For this reason, it is not necessary to prepare a plurality of stop control tables for each stop mode pattern of reels that have already stopped in order to control so that the winning combination is not aligned on any winning line at the time of automatic stop, and It is possible to control so that the winning combination is not achieved by simple control only by determining whether or not the winning combination is located on any winning line.

  In this embodiment, when a stop operation is performed, all reels are controlled by the table method. In the automatic stop control, except for the reel that stops last, the table is the same as when the stop operation is performed. For reels that are controlled by the method and stop last, refer to the non-winning position table and stop the reels when it is determined that the area number to which the number of steps from the current reference position belongs is the non-winning position. Regardless of whether the stop operation is performed or automatic stop control, the table method is controlled except for the reel that stops at the end, and the reel that stops at the end depends on the stop operation. If there is control by the control method, if the last reel is stopped by the stop operation, the winning combination by the internal lottery is not used. Controls to draw the corresponding symbol within the draw range so that it is aligned on the winning line, and kicks the symbol within the draw range so that the part not won by the internal lottery does not align on any winning line When performing the control and stopping the last reel by automatic stop, referring to the non-winning position table, it is determined that the area number to which the number of steps from the current reference position belongs is the non-winning position In this case, it is not necessary to prepare a stop control table for the reel to be stopped last.

  In a slot machine, the percentage of stop operations that are generally performed in the order of left reel, middle reel, and right reel is high. This is because humans tend to recognize side-by-side symbols and the like from the left side (for example, horizontal writing is written from left to right), and this order is most easily recognized.

  Further, in the slot machine 1 of the present embodiment, as shown in FIG. 1, stop switches 8L, 8C, and 8R are arranged in the horizontal direction, and generally there are many right-handed players and right-handed games. When a person performs an operation such as sliding the stop switches 8L, 8L, and 8R with the thumb, for example, it is easier to operate from the left to the right. It can be said that the ratio of the stop operation in the order of the left reel, the middle reel, and the right reel is high after the start.

  Further, in the slot machine 1 of the present embodiment, as shown in FIG. 1, the medal insertion portion 4 is disposed on the right side of the front door 1a as viewed from the player side, and the start switch 7 is disposed on the left side of the front door 1a. ing. This is because, in general, there are many right-handed players, the medal insertion part 4 is arranged on the right side so that the medal can be inserted with the right hand, and the start switch 7 that is easier to operate than the medal insertion is arranged on the left side. Because it is. Further, the slot machine 1 is not limited to the slot machine 1 of the first embodiment. In general slot machines, the start switch is usually arranged on the left side, and the stop operation is often performed from the left. Therefore, it can be said that after the start of the game, the percentage of stop operations in the order of the left reel, the middle reel, and the right reel is high.

  On the other hand, in the slot machine 1 of the present embodiment, when automatic stop control is performed, control is performed so that the stop is preferentially performed in the order of the right reel, the middle reel, and the left reel. That is, when all the reels are rotating, control is performed to stop in the order of right, middle, and left, and when any reel has already stopped, the reels that are still rotating are set to the right, middle, Control to stop with priority in the order of the left is performed.

  For this reason, when the automatic stop control is performed, the reels stop in a stop order different from the stop order with a high ratio generally selected unless the left reel is already stopped. When the stop control is performed, it is possible to determine to some extent whether or not the stop control is based on the automatic stop from the stop order.

  In this embodiment, when the winning flag for replay is set, if the left reel is first stopped, the combination of “replay” can be arranged in any of the winning lines L1 to L5. In contrast, when the middle reel or the right reel is stopped before the left reel, the “replay” symbol is drawn on the winning line L2 or L5 and the winning of the bell is performed. When the left reel is first stopped when the flag is set, control is performed so that a combination of “bells” can be arranged in any of the winning lines L1 to L5. When the reel or the right reel is stopped before the left reel, control for drawing the “bell” symbol on the pay line L1 is performed. In other words, in order to simplify stop control when stop operations are performed in a stop order other than the stop order that is generally selected, the left reel is first stopped in games where replays or bells are won. In other words, in general, when a reel having a high ratio of stopping first is stopped first, the control in which the winning combination of all the winning lines L1 to L5 can be matched, that is, display modes are various. When the reels other than the left reel are stopped before the left reel, that is, when the reels that are generally low in the first stop ratio are stopped first, However, control that aligns only with a specific winning line among the winning lines L1 to L5, that is, control that simplifies the display mode is performed.

  In addition, when performing automatic stop control as described above, control is performed so that the right reel, the middle reel, and the left reel are stopped in order, so if the bell or replay is won, the left reel Since the reels are stopped in the order of right and middle, except that is already stopped, at that time, the winning combination is controlled so that only the specific winning line among the winning lines L1 to L5 is aligned. When the automatic stop control is performed with these bells and replays selected, the middle and right reels have a bell on a specific winning line, except when the left reel is already stopped. Alternatively, a display mode in which the replay symbols are stopped and the bell or replay is not aligned on the winning line on the left reel on which the bell or replay symbol is stopped in the middle and right reels is provided.

  In this way, if automatic stop control is performed with the bell or replay being elected, whether or not the display mode is derived from the automatic stop with the bell or replay being elected. Can be determined to some extent.

  In particular, in the present embodiment, reach eyes and chance eyes that are established by deriving a specific display result on the left reel are adopted, and these reach eyes and chance eyes can be established with automatic stop. However, at least when the bell or replay is elected, it can be determined to some extent whether it is derived from the display mode due to the automatic stop. In spite of being invalid, it is possible to reduce the misunderstanding of the player when the reach or chance is derived.

  In this embodiment, when the winning flag for replay is set, if the middle reel or the right reel is stopped before the left reel, a “replay” symbol is displayed on the winning line L2 or L5. When pulling-in control is performed and the bell winning flag is set, if the middle reel or the right reel is stopped before the left reel, the “bell” symbol is drawn on the winning line L1. However, when a replay or bell wins and the reels other than the left reel are stopped first, the winning line for drawing the winning symbol is not limited to the above, and the winning symbol is The winning line to be drawn is limited to a specific predetermined winning line (multiple or singular) that is smaller than the winning line that draws the winning symbol when the left reel is first stopped. Or if the.

  Further, in this embodiment, a combination that is established only by stopping “cherry” on the winning line of the left reel, that is, a combination that is established by only one of the reels is determined. Unless the reel in which the winning combination is established before the control is already stopped, the control for stopping the reel at the end is performed. For this reason, even when a winning combination with only one of the reels is won, when the automatic stop control is performed, the order in which the reels are stopped is changed, or when the left reel is not the final stop reel, the same Since there is a possibility that the roles will be aligned in spite of automatic stop, the control for stopping the left reel may be different from the control when stopping by the stop operation, or the order of stopping the reels Since there is no need to change the automatic stop control, it is possible to make the automatic stop control always the same control. Therefore, even when a combination that is realized by only one of the reels is adopted, the reel accompanying the automatic stop is used. The stop control is not complicated.

  Further, in this embodiment, when the automatic stop control is started, the stop switches 8L, 8C, 8R from that point until at least all the reels stop (actually, they are activated in the next game). Since the detection of this operation is invalidated, it is possible to prevent the player from being confused as to whether the derived display result is due to the stop operation by the player or due to the automatic stop. Thereby, for example, it is possible to reduce the misunderstanding of the player when the reach eyes or chance eyes are derived even though the reach eyes or chance eyes are invalid due to automatic stop. .

  Further, in this embodiment, when all reels are stopped by automatic stop, the reels are stopped by automatic stop control based on the automatic stop notification pattern. The player is informed that the chance eye or the reach eye is invalid, and the reach eye or the chance eye is derived even though the reach eye or the chance eye is invalid due to the automatic stop. Can be reliably prevented from being misunderstood.

  Also, in this embodiment, when all reels are stopped by automatic stop, the fact that the small role notification effect is invalid is notified because the reel is stopped by automatic stop control based on the automatic stop notification pattern. In the game where the small role announcement effect is executed, even if the notified general role does not win, there is a possibility that the general role won by the automatic stop may not have won. It is possible to recognize that the special role is not notified by the role announcement effect, and the role that was automatically stopped and notified in the game where the small role notification effect was executed will not win In such a case, it can be reliably prevented that the player is misunderstood if the special role is won.

  In addition, in the slot machine 1 as an embodiment of the present invention, it is necessary to open the front door 1a in order to perform some illegal act on the data stored in the RAM 41c as the data storage means. Even when the door opening signal is output based on the detection of opening of the front door 1a, it is possible to discover that there is a possibility that the above fraudulent acts have been performed, and to supply power to the slot machine 1 Can be detected by the door opening detection IC 98a even in the event of a power failure, so that the front of the slot machine 1 can be detected even when a power failure occurs when the slot machine 1 is turned off. By detecting the opening of the door 1a, it can be found that there is a possibility that an illegal act has been performed.

  That is, the game control board 40 on which the RAM 41c is mounted is disposed inside the housing 1b that constitutes the main body of the slot machine 1 as described above, so that the front door 1a locked by the locking device 200 is provided. By detecting the opening, it can be inferred that there has been a possibility that some sort of fraud has been performed on the RAM 41c or the like of the game control board 40 disposed inside the housing 1b.

  Here, the structure of the locking / unlocking apparatus 200 which can lock the front door 1a with respect to the housing | casing 1b in a present Example is demonstrated based on FIG. 22A is a schematic diagram showing a locked state of the front door, and FIG. 22B is a schematic diagram showing a unlocked state.

  The locking / unlocking device 200 is provided on the front door 1a side, and a cylinder lock 203 having a key hole 202a (see FIG. 1) into which a key 201 owned by an amusement store can be inserted, and a cylinder lock 202 A linkage member 203 which is fixed to the rear end of the cylinder shaft 202a projecting from the rear surface and rotates about the axis of the cylinder lock 202 in conjunction with the rotation operation of the key 201, and the rotation of the linkage member 203 Is fixed to the front door 1a, and a locking member 206 facing the up-and-down direction provided with a pivot shaft 205 that can be rotated in the horizontal direction. A fixing member 207 having a support shaft 209 that rotatably supports the upper and lower locking claws 204, and a biasing spring 208 that has a lower end attached to the fixing member 207 and biases the locking member 206 downward. From It is configured.

  A locking hole 210 is formed on a side of the locking member 206 in the locking member 206 so that a locking release claw 203a formed in the linkage member 203 is locked. A regulating member 212 that contacts the lower end of the latch release claw 203a and regulates the raising of the latch member 206 is fixed below. Further, an insertion hole 211 is formed above the locked hole 210 so that the reset claw 203b formed on the upper portion of the linkage member 203 can be inserted.

  As shown in the AA sectional view of FIG. 22A and the A′-A ′ sectional view of FIG. 22B, a reset switch 38 (see FIG. 22) is provided between the locking member 206 and the fixing member 207. 3), the detected piece 213 detected in the manner shown in FIG. 3 is arranged so as to be movable up and down, and the detected piece 213 is formed with a locked hole 214 for locking the reset claw 203b on the side of the insertion hole 211. In addition, an insertion hole 215 through which the locking release claw 203a can be inserted is formed below.

  On the other hand, the housing 1b is provided with upper and lower engaged pieces 220 to which the upper and lower engaging claws 204 are engaged when the front door 1a is closed, as shown in FIG. The latching member 206 is constantly biased downward by the biasing spring 208, so that the latching claw 204 is latched to the latched piece 220 in the closed state of the front door 1a, and the front door 1a Opening is regulated.

  The cylinder lock 202 makes the cylinder shaft 202b unrotatable when the key 201 is not inserted from the keyhole 202a on the front surface (locked state), and can rotate the cylinder shaft 202b when the key 201 is inserted. It has an internal mechanism.

  Further, in the vicinity of the upper locking claw 204, the door switch 28 detects the locking position retracted from the locking position locked to the locked piece 220, that is, the locking claw 204 retracted to the locking release position. Is provided (see FIG. 22B).

  The operation of the locking / unlocking device 200 configured as described above will be described. First, in the locked state shown in FIG. 22A, the locking release claw 203a of the linkage member 203 is AA in FIG. As shown in the cross-sectional view, in the locked state where the locking claw 204 is locked to the locked piece 220, the locking claw 204 is located at the retracted position retracted outward from the locked hole 210. Therefore, in the state where the front door 1a is opened, the locking claw 204 is biased to the locking position by the biasing spring 208, but the key 201 does not have to be inserted into the keyhole 202a when the front door 1a is closed. However, ascending of the locking member 206 is not restricted by the locking release claw 203a of the linkage member 203, which cannot be rotated by the cylinder lock 202, the locking can be achieved by simply pushing the front door 1a. After the claw 204 is pushed down by the locked piece 220, it is returned to the locking position by the urging force of the urging spring 208 and is locked to the locked piece 220. That is, the locking operation by the key 201 when closing the front door 1a is not necessary.

  However, in such a locked state, as described above, the retraction position where the unlocking claw 203a of the linkage member 203, which cannot be rotated by the cylinder lock 202, is retreated outward from the locked hole 210. Therefore, the locking release claw 203a cannot restrict the lifting of the locking member 206. However, when the locking member 206 is lifted without the linkage member 203, The restricting member 212 that has risen together with the stop member 206 comes into contact with the lower end of the unlocking claw 203a, and the rise is restricted. That is, since the movement of the locking claw 204 from the locked piece 220 to the unlocking position is restricted, in the locked state, for example, a fraudulent instrument such as a cell from the gap between the butted surfaces of the front door 1a and the housing 1b. It is difficult to open the front door 1a by forcibly releasing the locking state by moving the locking claw 204 directly in the locking release direction by inserting the locking member 206 or the like. That is, the rotation of the cylinder lock 202 and the linkage member 203 based on the key operation by the unlocking (unlocking) key 201 that can be unlocked (unlocked) by the locking claw 204 (regular unlocking). The locking claw 204 cannot be moved in the unlocking direction by an unlocking operation (for example, an illegal unlocking operation such as forcibly raising the locking member 206) that does not depend on the operation). Can be effectively prevented.

  When opening the front door 1a, the key 201 is inserted into the key hole 202a and rotated clockwise as shown in FIG. 22 (b), so that the linkage member 203 rotates in conjunction with this, The locking release claw 203a enters the locked hole 210 and is locked to the upper edge of the opening of the locked hole 210 to raise the locking member 206. As a result, the locking claw 204 rotates from the locking position to the locking release position, so that the front door 1a can be opened.

  Note that the door switch 28 detects that the locking claw 204 has moved to the unlocking position, and outputs a door opening signal to an external device. Can be managed.

  In particular, the door switch 28 does not detect the movement of the front door 1a, but the locking piece 204 for locking the front door 1a to the locked piece 220 of the housing 1b in the unlocking direction. By detecting the movement as opening of the front door 1a, a structure such as a push switch for detecting the opening of the front door 1a becomes unnecessary, so that the structure can be simplified. Further, since the front door 1a cannot be opened unless the locking claw 204 is locked to the locked piece 220, the front door 1a can be opened compared to the case where the opening of the front door 1a is detected at the position of the front door 1a. The opening of the door 1a can be reliably detected.

  In this embodiment, the door switch 28 is provided so as to detect the locking piece 204. However, for example, the locking member 206 that interlocks with the locking operation or the unlocking operation of the locking piece 204 is detected. Alternatively, the front door 1a may be detected when the front door 1a is located at the closed position.

  In this embodiment, the door opening signal is output to the outside based on the fact that the door switch 28 serving as the opening detecting means detects the locking piece 204 positioned at the locking release position (door switch 28; on). However, for example, the door switch 28 detects the locking piece 204 positioned at the locking position, and the locking piece 204 is retracted to the locking release position so that the locking piece 204 is not detected. (Door switch 28; off), a door opening signal may be output to the outside.

  Further, both a locking door switch for detecting the locking piece 204 at the locking position and a locking release door switch for detecting the locking piece 204 at the locking release position are provided, and the door is opened based on the detection status of both switches. The signal may be output to the outside. Further, a main body door switch for detecting the closed position or the open position of the front door 1a itself is provided, and a door opening signal is output to the outside based on the detection status of the locking door switch, the unlocking door switch, and the main body door switch. You may make it do.

  Further, a door opening signal may be output to the outside based on a plurality of door switch detection situations such as the locking door switch, the locking release door switch, and the main body door switch. Specifically, for example, when the detection pattern of each door switch is a normal detection pattern (for example, locking door switch; off, unlocking door switch; on, main body door switch; off), the door opening signal is external. The detection pattern of each door switch is a detection pattern other than the normal detection pattern, that is, an abnormal detection pattern (for example, a lock door switch; on, a lock release door switch; on, a main body door switch; off), the door opening signal may not be output to the outside. Further, when the detection pattern of each door switch is the abnormal detection pattern, the door opening signal is not output to the outside, and a notification that each door switch is detected in an abnormal pattern (for example, the door opening signal is A different error signal or the like may be output).

  Further, the door switch 28 may be a push switch having a pressing portion pressed by the locking piece 204 retracted to the locking release position, or may be an optical sensor or the like, and its type is not limited. Absent.

  When the key 201 is inserted into the key hole 202 a and rotated counterclockwise, the linkage member 203 rotates in conjunction with this, and the reset claw 203 b is locked to the lower opening edge of the locked hole 214. Thus, the reset piece 213 is lowered, whereby the lower end of the reset piece 213 is detected by a reset switch 38 (not shown).

  In the slot machine 1 according to the present embodiment, the door opening detection IC 98a of the door opening detection circuit 98 is connected to a storage unit such as a RAM (not shown) provided therein based on the output of the door opening signal. The date and time information acquired from the timepiece device 97 is stored as door opening history information indicating that the door 1a has been opened, and the sub control unit 91 activates the main control unit 41, that is, activates the sub control unit 91. At this time, the door opening history information acquired from the door opening detection IC 98a and stored in the RAM 91c is displayed on the liquid crystal display 51, so that a door opening signal is output to a hall computer or the like outside the slot machine 1. Even if not, the opening state of the front door 1 a can be confirmed by the slot machine 1.

  Further, the sub-control unit 91 displays a date / time setting item as one of the items on the menu screen displayed on the liquid crystal display 51 when the date / time information of the clock device 97 is not set at the time of activation. The opening history of the front door 1a can be managed based on the date and time information, and the date and time can be managed thoroughly.

  In addition, connections between the cable side connectors 610a to 610f provided on the cables 600a to 600d as the door opening signal cables for outputting the door opening signal and the board side connectors 620a to 620f provided on the respective boards are illustrated. If the release restriction part that cannot be released is formed unless the release restriction part related to the connection with the connector is destroyed by the restriction member that is not connected, the connector connection of the door opening signal cables 600a to 600d is released. This prevents unauthorized actions that prevent the door opening signal from being output to an external device, and if the connector connection is released, the trace remains, indicating that the wrong actions may have occurred. Can be surely discovered.

  Although the embodiments of the present invention have been described with reference to the drawings, the present invention is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. Needless to say.

  For example, in the above-described embodiment, when the power supply to the slot machine 1 is stopped, that is, at the time of a power failure, the door switch 28 as an opening detection means for detecting the opening of the front door 1a, the opening signal output means for outputting a door opening signal. Backup power for driving the power supply board 100, the door opening detection IC 98a for storing the door opening history information detected by the door switch 28, and the like was supplied by a capacitor provided on the board. For example, the battery may be supplied from a substrate or a rechargeable battery provided outside the substrate.

  Moreover, in the said Example, the capacitor | condenser C10 which is a backup power supply which drives the door switch 28 which detects the opening of the front door 1a at the time of a power failure, and the door which memorize | stores the door opening history information detected by the door switch 28 at the time of a power failure The capacitor C11, which is a backup power source for driving the opening detection IC 98a, is provided separately. For example, the door opening detection IC 98a is mounted on the power supply board 100, and the backup power source for driving the door switch 28 and the door opening detection IC 98a is integrated. You may make it supply from one capacitor | condenser, a rechargeable battery, etc.

  In the above embodiment, the door opening signal is output to a hall computer (not shown) as an example of an external device. However, the external device is not limited to the hall computer. 1 may be output to an island controller or the like provided on a gaming machine installation island or the like.

  In the above embodiment, when the sub-control unit 91 is activated, that is, when the slot machine 1 is energized, a menu screen that allows browsing of the door opening history is displayed. Based on the information, if the opening of the front door 1a is detected during a power failure outside business hours and the door opening history information is updated, this is indicated through a predetermined browsing display operation when the slot machine 1 is energized. It may be displayed on the liquid crystal display 51 or the like without doing so, and it is possible to prevent an employee of the game shop from overlooking the opening of the front door 1a outside business hours.

  In the above embodiment, when the sub-control unit 91 is started, that is, when the slot machine 1 is energized, a menu screen that allows browsing of door opening history information is displayed. When an operation is performed or when a browsing button (not shown) provided in the front door 1a or the housing 1b is operated, an operation that must be performed by opening the front door 1a, that is, an employee of a game shop Only when a specific operation that can only be performed is performed, a screen that allows viewing of door opening history information and date / time setting operation may be displayed. It is possible to prevent a non-member player or a third party from performing door opening history information and date setting operation easily.

  In the above embodiment, the CPU 91a of the sub control unit 91 acquires the door open history information from the door open detection IC 98a when the sub control unit 91 is activated, that is, when the slot machine 1 is energized. When acquisition of door opening history information is requested, for example, all door opening history information stored in the storage unit of the door opening detection IC 98a has been cleared due to the stop of power supply from the capacitor C11. In such a case, notification indicating that the door opening history information is cleared may be performed.

  In the above embodiment, as shown in FIG. 7, the value of the bit corresponding to the winning combination is 1 and the values of the other bits are 0 in the winning flag. In the winning symbol flag, the value of the bit corresponding to the winning combination is 1 and the values of the other bits are 0. Then, all the bits of the internal winning flag are inverted, and a logical product (AND) with the winning symbol flag is calculated, and when the result becomes 00H (all bits are 0), other than the regular winning, other than 00H (any one) When the bit becomes 1), it is determined that the prize is abnormal.

  On the other hand, as a first modified example, as in the above embodiment, after calculating the logical product (AND) of the value obtained by inverting all the bits of the winning flag and the winning symbol flag, all of the values thus calculated are calculated. The bits may be further inverted, and it may be determined that the regular winning is achieved when the result is FFH (all bits are 1), and the abnormal winning is determined when the result is other than FFH (any bit is 0).

  As a second modification, after calculating the logical sum (OR) of the winning flag and the value obtained by inverting all the winning symbol flags, all the bits of the calculated value are further inverted, and the result is The regular winning may be determined when 00H (all bits are 0), and the abnormal winning may be determined when other than 00H (any bit is 1). In this case, as in the above-described embodiment, it is determined whether or not the prize is abnormal by simply checking the value of the zero flag of the F register (flag register) indicating whether the calculation result is 00H, that is, whether the calculation result is zero. Can be determined.

  Further, as a third modified example, a logical sum (OR) of a winning flag and a value obtained by inverting all the bits of the winning symbol is calculated, and when the result becomes FFH (all bits are 1), a regular winning is obtained. , FFH other than (any bit is 0), it may be determined as an abnormal winning.

  As described above, also in the first to third modifications, the result of logical sum operation or logical product operation of the winning flag or the value obtained by inverting the winning flag and the winning symbol flag or the value obtained by inverting the winning symbol flag is other than 0. It is possible to determine whether or not it is an abnormal winning only by determining whether or not it is a value or a value other than 1.

  In the second and third modified examples, if the winning symbol flag set in accordance with winning is reversed in advance for all bits, that is, the value of the bit corresponding to the winning combination is 0. If the winning symbol flag is set so that the value of the bit becomes 1, the step of inverting all the bits of the winning symbol flag in the abnormal winning determination process becomes unnecessary.

  In the case of the first and second modified examples, when determining whether the calculation result is FFH, 1 is added to the calculation result, and the calculation result is FFH when the value after the addition overflows. When the overflow does not overflow, it is preferable to determine that the operation result is other than FFH. In such a case, the value of the carry flag in the F register indicating whether or not the operation result has overflowed is set. It is possible to determine whether or not it is an abnormal winning only by checking.

  Next, as in the above embodiment, the winning flag has a value of 1 corresponding to the winning combination, and the other bits have a value of 0, and the winning symbol flag corresponds to the winning combination. A description will be given of a modification in which, when the value of a bit is 1 and the values of other bits are 0, all flags do not invert all the bits and determine whether or not a winning combination is won. .

  In this modification, the winning flag is applied as an abnormal winning determination flag. Then, from the value of each bit of the internal winning flag, the value of the bit at the same position in the winning symbol flag is subtracted, and on the condition that the subtraction result does not become a negative number in all the bits, whether or not it is an abnormal winning Determine whether. For example, by subtracting the value of the 0th bit of the winning design flag from the value of the 0th bit of the winning flag to determine whether the subtraction result is a negative number, Subtract the value of the first bit of the winning symbol flag from the value of the next bit, that is, the first bit of the internal winning flag, and determine the result. Finally, all the bits from the 0th bit to the 15th bit In step (1), it is determined that the winning is not abnormal, on the condition that the subtraction result does not become a negative number.

  In such a case, it is possible to determine whether or not there is an abnormal winning only by confirming the value of the sign flag of the F register indicating whether or not the calculation result has become a negative number. Furthermore, as in the above-described embodiments and modifications, it is possible to determine whether the winning flag or the winning symbol flag is an abnormal winning without inverting the bit.

  In the above embodiment, a slot machine is applied as a gaming machine. However, the present invention is not limited to this, and the present invention is not limited to this, and may be applied to a gaming machine such as a pachinko machine that uses a gaming ball. good.
