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 identification information each identifiable, and in particular, such as a big bonus due to the occurrence of a special winning The present invention relates to a slot machine that shifts to a special gaming state that is advantageous to a player.

  This type of slot machine is equipped with various boards such as a game control board provided with a game control means for controlling a game, and these boards are switches that allow a player to proceed with the game. Electronic components such as a kind are connected via a cable.

  These cables for connecting the electronic components and the substrate are generally separable by releasing the connection at the connector in order to facilitate the assembling work and the wiring work at the time of manufacturing the slot machine. In addition, electronic parts are common parts that are used continuously without being replaced even when changing models, etc., so they are fixed to the main body of the slot machine. For example, game control boards are replaced when a failure or model change occurs. Therefore, for example, the game control board can be easily taken out from the main body and replaced by removing the cable side connector from the board side connector provided on the game control board to release the connection.

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

  For example, the driving tool is used to operate various switches and the like provided in the slot machine by causing the game control board to input and output signals that simulate the signals input and output from the various electronic components to the game control board. It is possible to automatically advance the game without playing. Therefore, for example, in a game store, etc., the regular connector connected to the board-side connector provided on the game control board is removed, and an unauthorized connector connected to the driving tool is connected instead. Can be input / output to / from the game control board at an appropriate timing to automatically advance the game, for example, it is possible to easily set a state in which a special winning combination with a transition to a special gaming state advantageous to the player is won, etc. it can.

  Therefore, in the case where illegal sales such as providing a slot machine set in a state where a special prize is won using such an illegal driving device to a player at the start of business at a game shop, There was a risk that the fairness of this would be impaired.

  In this type of gaming machine, in order to prevent replacement with a harness (cable) to which unauthorized parts are connected, a harness insertion hole formed with a smaller diameter than the harness side connector is provided. A connector cover that covers a connection portion between the side connector and the harness side connector is attached to a board case in which the control board is accommodated, thereby making it difficult to pull out the connector (for example, see Patent Document 1), or a board side connector. After connecting the connector and the harness-side connector, a connector that makes it difficult to pull out the connector by attaching a cover of the board case together with the connector has been proposed (for example, see Patent Documents 2 and 3).

JP 2006-198091 A Japanese Patent Laid-Open No. 2006-230652 JP 2006-230653 A

  However, in the methods described in Patent Documents 1 to 3, it is difficult to pull out the connector, thereby suppressing the use of the driving machine. It was possible to set the winning state in a winning state, and it was not possible to sufficiently eliminate the possibility that the fairness of the game would be lost.

When the power is turned on or when an initialization command from the CPU 41a is not inputted, a reset signal is sent to the CPU 41a. A reset circuit 49 to be applied and other various devices and circuits are mounted.

  The CPU 41a is provided with a plurality of registers (storage areas) for reading and writing data necessary for executing processing. Specifically, a flag register that mainly stores operation data, a general-purpose register that stores general-purpose data, a PC register that stores data indicating the position of the program being executed, a stack pointer (to be described later in the current stack area) An SP register storing an address indicating a position), an R register storing data indicating a memory block of the RAM 41c performing a refresh operation, which will be described later, and data indicating a position serving as a reference when referring to the storage area of the RAM 41c are stored.

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

  The main control unit 41 includes a signal input terminal DATA, and detection states of various switches connected to the game control board 40 are input to the input port via the signal input terminal DATA. The input states of these signal input terminals DATA are monitored by the CPU 41a, and the CPU 41a executes a basic process that shifts in stages according to the input states of the signal input terminals DATA, that is, the detection states of various switches.

  In addition, the CPU 41a has an interrupt function as described above, and can execute an interrupt process by interrupting the basic process when an interrupt occurs. In this embodiment, four types of interrupts of interrupts 1 to 4 can be executed. For each interrupt, a counter mode (signal input from a trigger terminal CLK / TRG provided separately from the signal input terminal DATA) is provided. Can be selected and set between an interrupt mode that generates an external interrupt according to the number of times) and a timer mode (an interrupt mode that generates an internal interrupt according to the number of clock inputs of the CPU 41a).

  In the present embodiment, among the interrupts 1 to 4, interrupt 2 is set to the counter mode, interrupt 3 is set to the timer mode, and interrupts 1 and 4 are unused. The trigger terminal CLK / TRG is connected to the above-described power failure detection circuit 48, and the CPU 41a generates an interrupt 2 in response to the input of the voltage drop signal output from the power failure detection circuit 48, and the power failure described later. Execute interrupt processing. Further, the CPU 41a generates an interrupt 3 every time the number of clock inputs reaches a certain number, that is, every certain time interval (about 0.56 ms in this embodiment), and performs a timer interruption process (main) described later. Run. Moreover, although the interrupts 1 and 4 are set to unused, the interrupts 1 and 4 may generate | occur | produce by noise etc. For this reason, when interrupts 1 and 4 occur, the CPU 41a executes an unused interrupt process that immediately returns to the original process.

  The CPU 41a is set to prohibit other interrupts during execution of interrupt processing based on the occurrence of any one of interrupts 1 to 4, and a plurality of interrupts occurred simultaneously. In this case, interrupts to be executed with priority in the order of interrupts 2, 3, 1, 4 are set. In other words, when interrupt 2 and other interrupts occur simultaneously, interrupt 2 is prioritized and when interrupt 3 and interrupt 1 or 4 occur simultaneously, interrupt 3 is prioritized. To run.

  Further, the CPU 41a temporarily stores the data in use stored in the register in a later-described stack area provided in the RAM 41c at the start of interrupt processing based on the occurrence of any of the interrupts 1 to 4. The data saved in the stack area at the end of the interrupt process is returned to the register.

  As the RAM 41c, a DRAM (Dynamic RAM) is used, and a refresh operation is required to maintain the stored data contents. The CPU 41a is provided with the above-described R (refresh) register for performing this refresh operation. The R register consists of 8 bits, and the lower 7 bits are automatically incremented every time the CPU 41a fetches an instruction from the ROM 41b, and the value is updated every execution time of one instruction. .

  In addition, the main control unit 41 is supplied with backup power from the power supply board 100 even during a power failure. While the backup power is being supplied, the CPU 41a performs a refresh operation and the data stored in the RAM 41c. Is to be retained.

  Further, the CPU 41a acquires the state of the stop switch 36 and the automatic checkout switch 29 at the time of start-up, and sets the stop function valid / invalid and the automatic checkout function valid / invalid in a specific register of the CPU 41a.

The random number generation circuit 42 defines a range of numerical values to be counted for each type of random number. In this embodiment, 0 to 16383 is defined as the range. The CPU 41a sends an instruction to the sampling circuit 43 in accordance with the processing to acquire the numerical value indicated by the random number generation circuit 42 as a random number (this function is hereinafter referred to as a hardware random number function). Random numbers for internal lottery, which will be described later, are not used as they are extracted by the hardware random number function, but are processed and used by software. Details thereof will be described in detail. The CPU 41a also has a function of updating a numerical value of a specific register by the above-described timer interrupt process (main), and acquiring the updated numerical value as a random number (hereinafter, this function is referred to as a software random number function).

  The disconnection monitoring IC 50 monitors the electrical connection state between the game control board 40 and the inserted medal sensor 31 and the electrical connection state between the game control board 40 and the effect control board 90, and these connection states. If one of these is released, a disconnection flag indicating that these connection states have been released is stored in a storage unit such as an EEPROM (not shown) provided in the disconnection monitoring IC 50. . In response to the disconnection flag confirmation request from the CPU 41a, the disconnection monitoring IC 50 returns whether or not the disconnection flag is stored. At this time, the disconnection flag is cleared if it is stored in the storage unit.

  The disconnection monitoring IC 50 is also supplied with backup power in the event of a power failure. For example, unless the power failure state continues for 2 to 3 days, an electrical connection between the game control board 40 and the inserted medal sensor 31 is performed. Monitoring of the connection state and the electrical connection state between the game control board 40 and the effect control board 90 can be continued.

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

  The effect control board 90 is connected with the selection switch 56 and the determination switch 57 described above, and detection signals of these connected switches are input. Further, the door opening switch 28 described above is connected via the power supply board 100 and the photocoupler PC 10 (see FIG. 4) mounted on the power supply board 100, and the detection signal of the door opening switch 28 is input. ing.

  Electrical components such as a liquid crystal display 51 (see FIG. 1), a rendering effect LED 52, speakers 53 and 54, and a reel LED 55 disposed on the front door of the slot machine 1 are connected to the rendering control board 90. The components are driven based on control by a later-described sub-control unit 91 mounted on the effect control board 90.

  Similar to the main control unit 41, the effect control board 90 includes a microcomputer having a CPU 91a, ROM 91b, RAM 91c, and I / O port 91d. The effect control board 90 includes a sub control unit 91 for effect control and an effect control board 90. A liquid crystal driving circuit 92 that controls the driving of the connected liquid crystal display 51, a lamp driving circuit 93 that controls the driving of the effect LED 52 and the reel LED 55, an audio output circuit 94 that controls audio output from the speakers 53 and 54, and a power source A reset circuit 95 that gives a reset signal to the CPU 91a when it is turned on or when an initialization command from the CPU 91a is not inputted, a switch detection circuit 96 that detects a detection signal inputted from switches connected to the effect control board 90, date information Clock device 97 that outputs time information including time information and front door 1a The door opening detection IC 98 and other circuits for storing the release history are mounted, and the CPU 91a receives the command transmitted from the game control board 40 and the detection of the switches connected to the effect control board 90, While performing various control for performing an effect, each part of the control circuit mounted in the effect control board 90 is controlled directly or indirectly.

  Similar to the CPU 41a of the main control unit 41, the CPU 91a 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, when an interrupt is generated based on the input of the strobe signal (INT), the CPU 91a interrupts the process even when an interrupt process based on another interrupt is being executed. The command reception interrupt process is executed at the top, and even if another interrupt occurs at the same time, the command reception interrupt process is executed with the highest priority.

  The sub-control unit 91 is supplied with backup power in the event of a power failure. While the backup power is supplied, the CPU 91a performs a refresh operation and the data stored in the RAM 91c is stored. It is supposed to be retained.

  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.

  When the door opening detection IC 98 detects a door opening signal from the door opening switch 28, that is, when the front door 1a is opened, it acquires date and time information (date and time) at that time from the clock device 97, and The acquired date / time information is stored as door opening history information in a storage unit such as an EEPROM (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.

  Further, the opening of the front door 1a is detected by the door opening 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 can be done. 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 as door opening history information in the storage unit in the door opening detection IC 98, and the front door 1a is opened. Since the door opening signal indicating that it has been output to an external device (for example, a hall computer installed in the amusement store) via the external output board 1100 (see FIG. 6), it is installed in the amusement store. The open state of the front door 1a when the plurality of slot machines 1 are energized and when a power failure occurs, that is, the open state of the front door 1a at the time of business operation and when the store is closed is collectively displayed in an external device installed outside the slot machine 1. It can be managed.

  Next, details of wiring connection states between the game control board 40 and various game electronic components connected to the game control board 40 will be described with reference to FIG. FIG. 4 is a schematic view showing a wiring connection state between the game control board 40 and the game electronic components connected to the game control board 40.

  On the game control board 40, as described above, the single BET switch 5, the MAXBET switch 6, the start switch 7, the stop switches 8L, 8C, 8R, the settlement switch 10, the reset switch 23, the insertion medal sensor 31, and the reel sensor 33L. 33C, 33R, payout sensor 35, stop switch 36, automatic settlement switch 29, setting key switch 37, reset / setting switch 38, and effect control board 90 are connected.

  FIG. 4 shows a single BET switch 5, a MAXBET switch 6 that is operated when setting the number of bets among electronic components such as various switches and sensors connected to the game control board 40, and when starting a game. A start switch 7 that is operated, stop switches 8L, 8C, and 8R that are operated when the rotation of the reels 2L, 2C, and 2R is stopped, a inserted medal sensor 31 that detects a medal inserted to set a bet number; Reel sensors 33L, 33C, 33R for detecting the rotation of the reels 2L, 2C, 2R, a payout sensor 35 for detecting medals to be paid out when a winning occurs, and an effect control board 90 are shown, and other switches, Illustrations of sensors and the like are omitted.

  The gaming electronic components 5, 6, 7, 8, 31, 32 L, 32 C, 32 R, 33 L, 33 C, 33 R, 34, and 35 excluding the effect control board 90 send signals related to the progress of the game to the game control board 40. It is an electronic component that inputs and outputs. The signal related to the progress of the game is, for example, an operation for setting the number of bets to make the game startable, an operation for starting the game, or an operation for deriving the display results of the reels 2L, 2C, and 2R. Such as signals output to the game control board 40 in accordance with the progress of the game, detection of inserted medals, detection of the reference position of the reel, detection of the payout medals, etc. And a signal input to the game control board 40, a drive signal for driving the reels 2L, 2C, 2R according to the detection of the start operation, and a hopper for paying out medals when a winning occurs. A signal that is output from the game control board 40 in accordance with the progress of the game and that is input to the game electronic component.

  These gaming electronic components 5, 6, 7, 8, 31, 32L, 32C, 32R, 33L, 33C, 33R, 34, and 35 output signals to the game control board 40 as the game progresses. 1 electronic component and a second electronic component to which a signal from the game control board 40 is input as the game progresses.

  Specifically, the single bet switch 5 and the MAXBET switch 6 that are operated when setting the bet number and the inserted medal sensor 31 that detects a medal inserted to set the bet number are the operation or the medal of the medal. This is a first electronic component that outputs a BET signal to the game control board 40 based on the detection. Since the main control unit 41 performs the betting number setting process based on the reception of the BET signal, the betting number cannot be set without these electronic components. That is, since the game cannot be started unless the bet number is set, the one-sheet BET switch 5, the MAXBET switch 6, and the inserted medal sensor 31 are electronic components for games necessary for the progress of the game.

  The start switch 7 that detects an operation for starting a game is a first electronic component that outputs a start signal to the game control board 40 based on the detection of the operation. Since the main control unit 41 performs a process for starting the game (reel rotation process or the like) based on the reception of the start signal, the game cannot be started without this electronic component. That is, the start switch 7 is a game electronic component necessary for the progress of the game.

  Stop switches 8L, 8C, and 8R that detect an operation for deriving the display results of the reels 2L, 2C, and 2R are first electronic components that output a stop signal to the game control board 40 based on the detection of the operation. is there. The main control unit 41 performs processing for deriving the display result by stopping the rotation of the corresponding reels 2L, 2C, and 2R based on the reception of the stop signal. The display result of cannot be derived. That is, the stop switches 8L, 8C, and 8R are game electronic components necessary for the progress of the game.

  The reel sensors 33L, 33C, and 33R that detect the rotation of the reels 2L, 2C, and 2R are first electronic components that output a detection signal for the reference position of the reel to the game control board 40. The main control unit 41 does not have this electronic component because it performs processing to stop rotation by grasping the positions of the symbols of the corresponding reels 2L, 2C, and 2R based on reception of the detection signal of the reference position of the reel. In addition, derivation of display results of each reel 2L, 2C, 2R, determination of winning, etc. cannot be performed. That is, the reel sensors 33L, 33C, and 33R are game electronic components necessary for the progress of the game.

  A payout sensor 35 that detects medals to be paid out when a winning occurs is a first electronic component that outputs a medal payout signal to the game control board 40 based on the detection of the medals. The main control unit 41 performs payout processing for paying out the number of medals according to the generated winning based on the reception of the payout medal detection signal. Cannot be paid out. That is, the payout sensor 35 is a game electronic component necessary for the progress of the game.

  The reel motors 32L, 32C, and 32R that rotate the reels 2L, 2C, and 2R are second electronic components to which a drive signal output from the game control board 40 is input. The reel motors 32L, 32C, and 32R rotate the reels 2L, 2C, and 2R based on the input of the drive signal output from the game control board 40 and start the symbol variation display. Even if the reels 2L, 2C, and 2R are not actually rotated based on the above, the main control unit 41 receives the signals from the reel sensors 33L, 33C, and 33R after outputting the reel drive signals. The game can be controlled to proceed as the reel rotates. However, the timing at which signals are input to the game control board 40 from the reel sensors 33L, 33C, and 33R is an error unless the reel drive signal is output. In order to measure the output timing of the signal based on the detection of the rotation of the reel, a reel drive signal is required.

If the disconnection flag is stored, it is determined that the disconnection is abnormal as in the start-up. Then, the disconnection error error code is set in the register to control the disconnection error, and even in this case, the original state cannot be restored, and it is canceled until a new set value is set in the setting change mode described above. It will not be done.

  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. As in the case of the disconnection abnormality error, the RAM abnormality error state is not canceled even if the reset switch 23 or the reset / setting switch 38 is operated, and the area used by the CPU 41a in the area of the RAM 41c is not changed. All the areas other than the initialization area are initialized and cannot be restored to the original state, and are not canceled until a new setting 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, the RAM abnormal error state is not canceled even if the reset switch 23 or the reset / setting switch 38 is operated, and all the areas of the RAM 41c except for the area in use by the CPU 41a. The area is initialized and cannot be restored to the original state, and is not released 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 internal lottery process described later is a bet number according 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, the RAM abnormal error state is not canceled even if the reset switch 23 or the reset / setting switch 38 is operated, and all the areas of the RAM 41c except for the area in use by the CPU 41a. The area is initialized and cannot be restored to the original state, and is not released until a new set value is set in the setting change mode described above.

  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 to notify 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 or the like if the command is a power-on command indicating that the special role is won. 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 the winning flags for each of these combinations, the winning flag for the small role and the re-playing role is valid only in the game in which the flag is set, and is 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 winning flag for a special role is won, even if the combination of characters allowed by the flag cannot be aligned, the winning flag is not invalidated and is carried over to the next game. It becomes.

  FIG. 7 shows a winning combination table. The winning combination table is stored in the ROM 41b of the main control unit 41 in advance, and the combination numbers (1 to 14) assigned in the order in which the lottery is performed corresponding to the combination 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 according to the present embodiment, as shown in FIG. 7, 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. 7, 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 the state number is set to “2” or “3”, replay, cherry, 1 Sheet (1), sheet (2), bell, that is, a combination of combination and combination after combination number 10 is a target of internal lottery. When the game state is a regular bonus, that is, when the state number is set to “4”, cherry, 1 (1), 1 (2), bell, that is, a combination of the combination and combination of the combination number 11 and later. 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 a 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.

  The 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 the 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 gaming 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 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 this 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 exclusively drawn.

  Each combination and combination of combinations determined according to the gaming 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_flag) assigned to the RAM 41c. Set. The internal winning flag storage work (iwin_flag) 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 a winning flag for a 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 or combination of winning combinations is won, only the general winning combination storing 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 rotating and when the reel stops and the reel that is still rotating still remains. Create a stop control table for each reel. When any of the stop switches 8L, 8C, and 8R corresponding to the rotating reel is effectively detected, the stop control table of the corresponding reel is referred to and the slip of the referred stop control table is referred to. Based on the number of frames, control is performed to stop the rotation of the reels 2L, 2C, 2R corresponding to the operated stop switches 8L, 8C, 8R.

  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 table 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 this case, 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 table creation data, and the stop control table address of the unreacted reel corresponding to the stopped reel and the area number of the stop position of the reel is obtained from the identified table creation data. The stop control table for each stored reel is expanded to create a stop control table for the unstopped reels.

  Next, when the 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 corresponding to 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 where the stop operation is detected is shown. It stops at the stop reference position (in this 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 address of the storage area 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 the stopped reel). Therefore, when all of the gaming state, the internal winning state, and the reel stop status (and the stop position of the stopped reel) are the same, the reel is based on the same stop control table, that is, the same control pattern. The stop control is performed.

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

  In 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 so as to stop them together. The symbol of the winning combination is controlled to be stopped in a drawing range of up to 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 as to draw the maximum 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 within the draw range of up to 4 frames can be aligned and stopped on the winning line, the control is performed to align and stop them. 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 the re-game player is elected in the state where the special game has been carried over from before the previous game (Big Bonus (1) + Replay, etc.), the re-game player 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 simultaneously with 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, is a drawing range of 4 frames. 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 first stopped, 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 in succession. 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 first stopped, 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 No. 2-4, or “Bell Red 7 Bell” of No. 8-10, “Replay of No. 15-17 "Blue 7 Watermelon" stops and no display of the winning lines is 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 design stops, and the display mode in which none of the roles are aligned on the winning line and the display result of the right reel are “Replay Cherry Blue 7” of the 10th to 12th designs. 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 to 18 stops is the reach of all bonuses, and symbols 20, 20, 1 or 12 to 14 The display mode in which the symbol “Replay Watermelon Bell” has stopped and none of the combinations 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 by only one of the reels is defined. Except for the case where a reel whose role 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 in a stage (a range of less than one frame), that is, a position where the symbol corresponding to the area number stops in 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 disconnection error error or the RAM error error described above, and the CPU 41a in the area of the RAM 41c. All areas except for the area in use are initialized, cannot be restored to the original state, and are not canceled until a new set value is set in the setting change mode described above.

  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 to the internal winning flag storing work (iwin_flag) 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. 8, 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, 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 winning has been won, and when it is 0, it indicates that the winning combination has not won. The winning symbol flag is the same as the internal winning flag. As shown in FIG. 8, 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.

  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. Of 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 in which data that can be initialized at the end of the big bonus, such as a stop control table, a stop symbol, the number of medals paid out, and the total number of medals paid out in the big bonus, are stored. The special work 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 terminates the big bonus before the start of setting (before the transition to the setting change mode) and when an unrecoverable error (disconnection error, RAM error, abnormal winning error) occurs. When the data in the RAM 41c is not destroyed at the time of startup, when four initialization conditions at the end of one game are satisfied, four types of initials with different areas initialized according to each initialization condition To do.

  Initialization 1 is a state in which the setting key switch 37 is in an ON state at the time of start-up, and when shifting to the setting change mode, initialization performed before that and an error that cannot be recovered (disconnection abnormality error, RAM abnormality error, In the initialization 1, all the areas (including the unused area and the unused stack area) other than the used stack area are initialized in the storage area of the RAM 41c. The Initialization 2 is initialization performed at the end of the big bonus. In initialization 2, the general work, the unused area, and the unused stack area are initialized in the storage area of the RAM 41c. Initialization 3 is initialization that is performed when the setting key switch 37 is in an OFF state at the time of startup and the data in the RAM 41c is not destroyed. The used stack area is initialized. Initialization 4 is initialization performed at the end of one game. In initialization 4, an unused area and an unused stack area in the storage area of the RAM 41c are initialized.

  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, a stop command, an error command, an initialization command, a setting end 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 for setting 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 initialization command is a command indicating that the gaming state has been initialized and the start of the setting change mode, and is transmitted when the RAM 41c is initialized and shifts to the setting change mode.

  The setting end command is a command indicating the end of the setting change mode, 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 the 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. With reference to the control pattern corresponding to the type of command, the effect 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 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, initialization command, setting end 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 initialization command is received, a setting notification pattern for notifying that the setting is being changed is referred to. When the setting end command is received, the above-described standby pattern is referred to as a control pattern. In other words, when an initialization command is received, a notification during setting change is executed, and thereafter, when a setting end command is received, a 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 a special role is won is received, a notification effect for notifying the special role 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. When the initialization command is received in this state, the data in the RAM 91c is cleared. 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.

  When the sub-control unit 91 is activated, the CPU 91a performs a predetermined date / time setting operation screen (when date / time information is not set by the clock device 97, that is, when the date / time information is reset). (Not shown) is displayed on the liquid crystal display 51, and the operation of the selection switch 56 and the determination switch 57 is performed while the date / time setting operation screen is displayed. Control to set.

  The date and time (date, time) of the timepiece device 97 is set, for example, by connecting an external timepiece device (the timepiece device) to the connector on the effect control board 90 into which the connector of the wiring extending from the game control board 40 (effect relay board 80) is inserted. The sub-control unit 91 monitors the acquisition of the date / time setting command indicating the date / time information output from the external clock device, and also displays the date / time setting command output from the external clock device. The date and time of the clock device 97 mounted on the effect control board 90 may be set based on the acquisition. 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.

  Further, the CPU 91a requests the door opening detection IC 98 to acquire door opening history information at the time of activation. When the door opening detection IC 98 is requested by the CPU 91a to acquire door opening history information, the door opening detection IC 98 outputs all door opening history information stored at that time to the CPU 91a. Accordingly, the CPU 91a that has acquired the door opening history information stores all the door opening history information acquired in the door opening history area assigned to the RAM 91c, and updates the history information.

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

  The door opening detection IC 98 is supplied with backup power in the event of a power failure, and when opening of the front door 1a is detected in the event of a power failure, door opening history information (date / time information) is stored in the door opening detection IC 98. Since it is stored in the storage unit inside the opening detection IC 98, the door opening history information stored at the time of a power failure is stored and updated in the door opening history area of the RAM 91c when the CPU 91a is activated. ing.

  In addition, the CPU 91a controls the liquid crystal display 51 to display a predetermined menu screen that allows browsing of the above-described date and time setting operation screen, door opening history information, setting change history information, and the like at the time of activation. When any of the various menu items displayed on the menu screen is selected, processing corresponding to the selected item is performed.

  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.

  In this embodiment, as described above, when the date and time information of the clock device 97 is not set when the CPU 91a is activated, that is, when the date and time information is initialized, the date and time setting item is displayed on the menu screen. The menu screen cannot be cleared until the date and time information setting operation is performed, and the door opening history information and the like are not stored when the date and time information of the clock device 97 is not set. It will be possible to manage the history thoroughly.

  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 and peripheral IC (excluding disconnection monitoring IC 50), interrupt mode, stack pointer, etc. are initialized (Sa1), then the voltage drop signal detection data is acquired from the input port, and the voltage drop It is determined whether or not a signal is input, that is, whether or not the voltage is stable (Sa2), and when a voltage drop signal is input, other than whether or not a voltage drop signal is input Shifts to a loop process that does not perform any process.

  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 at step Sa6, the storage state of the disconnection flag is acquired from the disconnection monitoring IC 50 (Sa7), and it is determined whether the disconnection flag is stored (Sa8). If the electrical connection state between the game control board 40 and the inserted medal sensor 31 and the electrical connection state between the game control board 40 and the effect control board 90 are not released during a power failure, the disconnection flag is If the disconnection flag is stored, the state of electrical connection between the game control board 40 and the inserted medal sensor 31 or the game control board 40 and the effect control board 90 is not stored. Therefore, the error code indicating disconnection abnormality is set in the register (Sa9), and the process proceeds to the error processing shown in FIG.

  If the disconnection flag is not stored in step Sa8, the RAM parities of all the storage areas (including the unused area and the unused stack area) of the RAM 41c are calculated (Sa10), and whether the RAM parity is 0 or not. Is determined (Sa11). If the interruption interrupt process (main) is normally performed, the RAM parity should be 0. If the RAM parity is not 0 in the step of Sa11, the data stored in the RAM 41c is not normal. Therefore, an error code indicating a RAM abnormality is set in the register (Sa13), and the process proceeds to the error process shown in FIG.

  If the RAM parity is 0 in step Sa11, it is further determined whether or not the destructive diagnosis data is normal (Sa12). If power interruption interrupt processing (main) is performed normally, the data for destruction diagnosis should be set. If the data for destruction diagnosis is not normal in step Sa12 (data for destruction diagnosis is power interruption) Since the data in the RAM 41c is not normal also in cases other than 5A (H) stored sometimes, the error code indicating the RAM abnormality is set in the register (Sa13), and the process proceeds to the error processing shown in FIG.

  In the error processing, as shown in FIG. 10, 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 disconnection error, a RAM error, or an abnormal winning error (Sb3). In the case of an error code indicating an abnormal error or an abnormal winning error, after performing initialization 1 for initializing all the storage areas in the storage area of the RAM 41c except the used stack area (Sb4), The process shifts to a loop process in which no process is performed.

  If it is determined in step Sb3 that the error code is not an error other than a disconnection error, a RAM error, and 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, Return to step Sb5. 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 disconnection abnormality error, the RAM abnormality error, and the abnormal winning error, the error state can be canceled by operating the reset / setting switch 38 or the reset switch 23. If the error processing is due to a disconnection error, a RAM error, or an abnormal winning error, initialization 1 is performed to initialize all the storage areas of the RAM 41c except the stack area in use. When the reset / setting switch 38 or the reset switch 23 is operated, the error state is canceled and the original state is not restored.

  Returning to FIG. 9, if it is determined in step Sa12 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 (Sa14), the destruction diagnosis data is cleared (Sa15). Next, it is determined whether any special role is won in the state before the power interruption (Sa16). If any special role is elected in the state before the power interruption, A power-on command indicating winning is set (Sa17), and the process proceeds to step Sa19. If no special role is won in the state before power interruption, a power-on command indicating non-winning special role is set. (Sa18), the process proceeds to step Sa19.

  In step Sa19, each register is restored to the state before power interruption, that is, stored in the stack, interrupt is permitted (Sa20), and the process executed last before power interruption is returned to. When interrupt is permitted in step Sa20, timer interrupt processing is periodically executed, and accordingly, the power-on command set in step Sa17 or Sa18 is sent to 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 that initializes all the storage areas in the storage area of the RAM 41c except the used stack area (Sa21), The value stored in the set value work (0 at this time) is corrected to 1 (Sa22). Next, after setting the initialization command (Sa23), the interrupt is permitted (Sa24), and the setting change process shown in FIG. 11, that is, the setting change mode is entered (Sa25). When the interrupt is permitted in the step Sa24, the timer interrupt process is periodically executed, and the initialization command set in the step Sa23 is transmitted to the sub-control unit 91 accordingly. . After the setting change process in step Sa25 is completed, a setting end command is set (Sa26), and the process proceeds to the game process. The initialization command set in step Sa26 is transmitted to the sub-control unit 91 in the subsequent timer interrupt process.

  In the setting change process, as shown in FIG. 11, 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 the setting change process is entered. Is read out (Sc1).

  Thereafter, 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 (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 process returns to the flowchart of FIG. 9, and the game process is started.

  As described above, in the starting process, when the setting key switch 37 is not in the ON state, it is determined whether or not a disconnection flag is stored. If the disconnection flag is stored, the process proceeds to an error process. Further, it is determined whether or not the data stored in the RAM 41c is normal by determining whether or not the RAM parity is 0 and whether or not the data for destructive diagnosis is normal, and the data in the RAM 41c is normal. If not, the process proceeds to error processing. In the error processing due to the disconnection error error or the RAM error error, the error code indicating the disconnection error error or the RAM error error is displayed on the game auxiliary display 12 and then initialized so that it cannot return to the state before the power interruption. To initialize the RAM 41c and shift to a loop process in which no process is performed, so that the progress of the game is disabled. If the data in the RAM 41c is not normal, the interrupt is not permitted. Therefore, once the process proceeds to error processing due to a disconnection error or RAM error, the setting key switch 37 is activated and the interrupt is interrupted. Until interruption is permitted, 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 proceeds to error processing due to disconnection error or RAM error, the setting key switch 37 is activated and all the areas except the used stack area of the RAM 41c are initialized, and then the setting change process is performed. Until the setting value is newly selected and set by operating the reset / setting switch 38, the game cannot be progressed. 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. 12 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 the step Sd4, when it is determined in the step Sd3 that the rotation of all the reels 2L, 2C, and 2R is stopped, the winning is determined according to the display result derived for each reel 2L, 2C, and 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 of 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. 13 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, 1 is set as the first combination number to be drawn (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 set as the winning number to be drawn first.

  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 set 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 associated with the set number to be processed and the read set value. Read the address of the area. Then, the number of determination 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. The process proceeds to the step of Se14, and the number of determination values is determined by internal lottery. 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 is performed. 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.

  14 and 15 are flowcharts showing the control contents of the reel rotation process executed by the CPU 41a in 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. For example, it waits until the wait time elapses.

  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 stop switch operation 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. 16 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_flag (internal winning flag storage work) is inverted for all bits (Sg9), and iwin_flag is inverted for all bits (abnormal winning determination flag) and the winning symbol flag is 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_flag 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 shown in FIG.

  In this way, in the abnormal winning determination process, it is determined whether or not a winning has occurred at the time of automatic stop, whether or not there has been a duplicate winning, and whether or not a winning winning has not occurred. It is determined whether or not it is an abnormal winning, and if it is an abnormal winning, the process proceeds to error processing. In error processing due to an abnormal winning error, an error code indicating an abnormal winning error is displayed on the game auxiliary display 12, and then initialization 1 is performed to initialize the RAM 41c so that it cannot return to the state before power interruption. Since the process proceeds to a loop process in which neither process is performed, the progress of the game is disabled. Once the process shifts to an error process due to an abnormal winning error, the setting key switch 37 is activated in the ON state, and after all 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 of shifting to error processing due to an abnormal winning error, the state where the progress of the game is impossible is canceled on the condition that a new set value is selected and set by operating the reset / setting switch 38, and the game is resumed. It becomes possible to make it.

  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 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 index prohibited in the Si1 step is restored. 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 The final stop processing (Si24) to be magnetized, the storage state of the disconnection flag is acquired from the disconnection monitoring IC 50, and if the disconnection flag is stored, an error code indicating a disconnection error is set in the register, and the error processing shown in FIG. After the disconnection confirmation process (Si25) to be transferred to is sequentially executed, the register saved in the stack area in Si2 is restored (Si20), the interrupt prohibited in the Si1 step is permitted (Si21), and the interrupt Return to processing.

  In the disconnection confirmation process of Si25, when it is determined that the disconnection flag is stored, the error state due to the disconnection abnormality is controlled, so that the setting key switch 37 is activated and newly set. Until the value is selected and set, the game cannot proceed.

  FIG. 19 is a flowchart showing the control contents of the stop switch process executed in the timer interrupt 4 of the timer interrupt process (main) described above by the CPU 41a.

  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. 20 shows a power interruption interrupt process (main) executed by the CPU 41a in response to the occurrence of the interrupt 2, that is, when the 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), after initialization of built-in devices and peripheral ICs (excluding the door opening detection IC 98), interrupt mode, stack pointer, etc. (Sr1), 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 Sr7.

  If the RAM parity is not 0 in step Sr4, the data stored in the RAM 91c is not normal, so the RAM 91c is initialized (Sr13), the standby pattern is set as the control pattern (Sr14), and the command is received. Only the interrupt process 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 setting notification pattern is set as a 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. 22 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 no command is stored in the buffer, the process proceeds to step Ss7. If a 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 the step of Ss6, the effect control process for controlling various effect devices such as the liquid crystal display 51, the effect effect LED 52, the speakers 53, 54, etc. is executed according to the control pattern set in the step of Ss7, and the process proceeds to the step of Ss7. .

  In step Ss7, a date / time setting process for setting the date / time of the clock device is executed, and the process proceeds to step Ss8. In the date / time setting process, date / time information (date, time) is acquired from the clock device 97, and 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 information setting processing) is performed. That is, when the date / time information acquired from the clock device 97 is reset when the CPU 91a is activated, a menu screen capable of selecting the date / time information setting screen is displayed reliably, and the date / time information is set at that time. If no is performed, 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 the step of Ss8, the door opening process for updating the door opening history information is executed, and the process proceeds to the step of Ss9. In the door opening process, acquisition of door opening history information stored in the storage unit of the door opening detection IC 98 is requested, and all the door opening history information stored at that time is updated. The door opening history information is acquired, and the acquired door opening history information is updated with respect to the door opening history information stored in the RAM 91c.

  In step Ss9, after updating the values of various counters such as a random number counter in the RAM 91c, the process proceeds to step Ss10 to check 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, 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.

  In this embodiment, it is difficult to connect the driving tool by restricting the release of the connector connection between the game control board 40 and the game electronic component. Specifically, the connector connection between the game control board 40 and the inserted medal sensor 31, that is, the connection between the board side connector 620a of the game control board 40 and the cable side connector 610a of the cable 600a, the cable side connector 611a of the cable 600a. And the connection between the board-side connector 621a of the operation unit relay board 110 and the connection between the board-side connector 622g of the operation part relay board 110 and the cable-side connector 612g of the cable 601g are restricted from being released from each other. The connection between the board side connector 620a and the cable side connector 610a is restricted by the connector restricting member 500a, the connection between the cable side connector 611a and the board side connector 621a, and the connection between the board side connector 622g and the cable side connector 612g. The release of the connection is regulated by the connector regulating member 650.

  Further, by restricting the release of the connector connection between the game control board 40 and the effect control board 90, it is difficult to release the connection between the game control board 40 and the effect control board 90. Specifically, the connector connection between the game control board 40 and the effect control board 90, that is, the connection between the board side connector 620d of the game control board 40 and the cable side connector 610d of the cable 600d, the cable side connector 611d of the cable 600d. And the board side connector 621d of the production relay board 80, the board side connector 622p of the production relay board 80 and the cable side connector 612p of the cable 601p, the cable side connector 613p of the cable 601p and the board side of the production control board 90 The connection with the connector 623p is restricted from releasing the connection between these connectors. The connection between the board-side connector 620d and the cable-side connector 610d is restricted by the connector restricting member 500b, the connection between the cable-side connector 611d and the board-side connector 621d, and the connection between the board-side connector 622d and the cable-side connector 612d. Connection and connection between the cable-side connector 613p and the board-side connector 623p are restricted by a connector restricting member (not shown).

  Further, the release of the connector connection between the power supply board 100 and the door opening switch 28, the power supply board 100 and the effect control board 90, the power supply board 100 and the external output board 1100, and the external output board 1100 and an external device (not shown) is regulated. Therefore, it is difficult to release the connection with all the connectors related to the detection of the opening of the front door 1a. Specifically, the connector connection between the power supply board 100 and the door opening switch 28, that is, the connection between the board side connector 1620a of the power supply board 100 and the cable side connector 1610a of the cable 1600a, the power supply board 100 and the effect control board 90 Connector connection between the cable side connector 1610b of the cable 1600b and the board side connector 1620b of the power board 100, the cable side connector 1610c of the cable 1600b and the board side connector 1620c of the effect control board 90, the power board 100 and the outside Connector connection between the output board 1100, that is, connection between the cable side connector 1610d of the cable 1600c and the board side connector 1620d of the power supply board 100, cable side connector 1610e of the cable 1600c and the external output board 11 Connection with the 0 board-side connector 1620e, connector connection between the external output board 1100 and an external device (not shown), that is, connection between the board-side connector 1620f of the external output board 1100 and the cable-side connector 1610f of the cable 1600d. Release of the connection between the connectors is regulated by a connector regulating member (not shown).

  These connector restricting members are configured to be able to restrict the removal of the cable side connector from the board side connectors connected to each other, and the connection release restricting state that makes the release impossible unless the release restricting part related to the connection with the connector is destroyed. As long as it is configured to leave a trace when the connection release restriction state is released, its form is arbitrary and can be variously changed.

  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.

  Next, the state of attachment of the connector restriction members 500a and 500b to the board case 200 and the state of attachment of the board case 200 to the housing will be described.

  First, the game control board 40 is accommodated in the lower case 201 and the upper case 203 constituting the board case 200 to be in a sealed state. In order to seal the lower case 201 and the upper case 203, the engaging portions 230 of the corresponding upper case 203 are engaged with the two pairs of locking portions 210 of the lower case 201, respectively, One of the sealing pieces 211 of the case 201 and the corresponding sealing piece 231 of the upper case 203 are fixed with a one-way screw.

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

  Then, by fixing the sealing piece 211 and the sealing piece 231, the longitudinal movement of the upper case 203 with respect to the lower case 201 is restricted, and as a result, the upper case 203 is engaged with the locking portion 210 of the lower case 201. The release of the engagement of the joint portion 230 is also restricted, and the upper case 201 and the lower case 203 are integrated with the game control board 40 accommodated therein, and the sealing piece 211 and the sealing piece 231 are broken. Otherwise, it will not be possible to open.

  Next, the attachment side members 510 and 510 constituting the connector restricting members 500a and 500b are attached to the board case 200 in which the game control board 40 is sealed. The attachment-side member 510 is elastically deformed on both side pieces 510d and 510d outward and attached to the step 203b (step 203a) of the upper case 203. Then, by releasing the elastic deformation, the engaging pieces 511 and 511 are attached by engaging with the engaging grooves 212 and 212 on the back surface of the lower case 201. At this time, the base piece 510a and the upper pieces 510c and 510c of the attachment-side member 510 are in contact with the upper surface of the step 203b (step 203a) and the bottom of the recess 203f (depression 203e) of the upper case 203, respectively. The notch 512 provided in the upper case 203 coincides with the insertion hole 234a (insertion hole 234b provided in the recess 203e) provided in the recess 203f of the upper case 203, and these notch 512 and insertion hole 234a (insertion hole 234b). The board-side connector 620a (board-side connector 620d) of the game control board 40 accommodated in the board case 200 is exposed from the inside of the board case 200 to the outside.

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

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

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

  When the board case 200 to which the attachment side member 510 is attached is fixed to the attachment base 250 (housing) so as not to be removed, as shown in FIG. 29A, the side piece 510d of the attachment side member 510 is provided. , 510d abuts against the inner surfaces of the side walls 250b, 250c of the mounting base 250, and is held between the two sides 510d, 510d of the mounting side member 510 to restrict outward deformation thereof. It becomes impossible to remove from 200.

  Next, as shown in FIG. 25, with respect to the board side connectors 620a and 620b of the game control board 40 exposed through the insertion holes 234a and 234b of the board case 200 and the notches 512 of the base piece 510a in the attachment side member 510. After connecting the cable side connector 610a of the cable 600a and the cable side connector 610d of the cable 600d, respectively, the board side connector 620a and the cable side connector 610a, and the board side connector 620d and the cable side connector 610d are connected. As shown in FIG. 5, the cover portion 521 of the connector cover 520 covers the upper side of the cable side connector 610a and the cable side connector 610d, and the engagement tube 522 of the connector cover 520 is engaged with the engagement hole portion 513 in the attachment side member 510. Fits into the hole 513a Make. As a result, the engaging portions 523 and 523 of the locking cylinder 522 abut against the inner periphery of the locking hole 513a and elastically deform inward. At this time, when the engaging portions 523 and 523 are positioned so as to cover the cable-side connector 610a and the cable-side connector 610d with the covering portion 521, the engaging portions 523 and 523 are, Positioned in the shallow groove portions 514a and 514a, the locking cylinder 522 is further fitted, and the locking claws 523a and 523a at the tips of the engaging portions 523 and 523 are inserted into the shallow groove portions 514a and 514a of the engaging grooves 514 and 514, respectively. By reaching, as shown in FIG. 27 (a), the inward elastic deformation of the engaging portions 523 and 523 is released, and the locking claws 523a and 523a are engaged with the shallow groove portions 514a and 514a, respectively. The upward movement of the locking cylinder 522 is restricted, and the side surface 521a of the covering portion 521, the side surface of the board side connector 620a and the cable side connector 610a, the base The side surfaces of the side connector 620d and the cable side connector 610d come into contact with each other and the rotation of the locking cylinder 522 with respect to the locking hole 513 is restricted, so that the mounting side member 510 and the connector cover 520 are connected and integrated. The connector restricting member 500a thus formed is formed. In this state, since the engaging portions 523 and 523 are covered with the locking hole portion 513, it is impossible to elastically deform the engaging portions 523 and 523 inward from the outside, and the connector cover 520 or the attachment side member Unless 510 is broken, the connector cover 520 cannot be removed from the attachment side member 510.

  When the connector cover 520 is detachably attached to the attachment side member 510, as shown in FIGS. 29 (a) and 29 (b), a part of the upper surface of the cable side connector 610a and the cable side connector 610d is covered by the covering portion 521. Accordingly, the movement of the cable side connector 610a and the cable side connector 610d in the pulling direction from the board side connector 620a and the board side connector 620d is restricted, and the cable side connector 610a and the board side connector 620a of the cable side connector 610d and the board side connector are controlled. The removal from 620d is regulated.

  In this way, with the attachment side member 510 attached to the board case 200, the board case 200 is fixed to the housing, and then the cable side connector 610a and the cable side connector 610d are connected to the board side connector 620a and the board side connector 620d. In this state, the board-side connector 620a and the board-side connector 620d are attached to the attachment-side member 510 so as to partially cover the board-side connector 620d from above. The board-side connector 620d cannot be removed.

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

  To release the connection between the cable-side connector 610a and the board-side connector 620a and the connection between the cable-side connector 610d and the board-side connector 620d, the attachment-side member 510 or the connector cover 520 is broken and the connector cover 520 is attached to the attachment-side member. 510, or the sealing piece 232 or the fixing member 255 of the board case 200 is broken, and the board case 200 is detached from the mounting base 250, and the mounting side member 510 with the connector cover 520 attached is removed. It is necessary to remove from 200.

  For example, when it is necessary to remove the cable-side connector 610a or the cable-side connector 610d from the board-side connector 620a or the board-side connector 620d due to a failure of the cables 600a, 600d, etc., it is removed by the former method, When replacing the entire case 200, the latter method may be removed.

  First, when replacing the cable 600a (cable 600d), when it is necessary to remove the cable-side connector 610a (cable-side connector 610d) from the board-side connector 620a, the connector constituting the connector regulating member 500a (connector regulating member 500b) The method of removing the cover 520 from the attachment-side member 510 will be described. First, the connecting piece 522a that connects the cover portion 521 of the connector cover 520 and the locking cylinder 522 is broken with a tool such as a nipper. As a result, the covering portion 521 is separated and the locking cylinder 522 can be rotated with respect to the locking hole portion 513. In this state, by rotating the locking cylinder 522 counterclockwise as viewed from above, the engaging portions 523 and 523 move from the shallow groove portions 514a and 514a of the engaging grooves 514 and 514 to the positions of the deep groove portions 514b and 514b. Then, as shown in FIG. 27A, from the state where the locking claws 523a and 523a are engaged with the shallow groove portions 514a and 514a, as shown in FIG. 27B, the locking claws 523a and 523a The shallow groove portions 514a and 514a are disengaged. As a result, the locking cylinder 522 can be moved upward. As shown in FIG. 27C, when the locking cylinder 522 is pulled upward, the locking claws 523a and 523a are engaged with the deep grooves 514b and 514b. However, in this state, since the engaging portions 523 and 523 are exposed, the engaging portions 523 and 523 can be elastically deformed inward. 523a and the deep groove portions 514b and 514b are disengaged, and the locking cylinder 522 can be detached from the attachment side member 510, whereby the connector cover 520 is completely separated from the attachment side member 510, and the connector cover 520 Since the restriction of the movement in the pulling direction of the cable side connector 610a (cable side connector 610d) by the cable is also released, the cable side connector 610a (cable side Connector 610d) and it is possible to release the connection between the board-side connector 620a (substrate side connector 620d).

  When the connector cover 520 is removed from the attachment-side member 510, the covering portion 521 and the locking cylinder 522 are broken, and once broken, the original state is not restored. Therefore, the cable-side connector 610a (cable-side connector 610d) and the board The trace which canceled connection with the side connector 620a (board | substrate side connector 620d) will remain.

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

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

  Further, according to this method, the sealing piece 232 of the board case 200 is broken and remains on the fixing member 255, but the attachment side member 510 can be removed from the board case 200 without removing the connector cover 520 from the attachment side member 510. Therefore, by attaching the attachment side member 510 with the connector cover 520 assembled to the new board case 200 in which the game control board 40 is accommodated for replacement, the cable side connector 610a and the board side in the new board case 200 are attached. The connection side with the connector 620a and the release of the connection between the cable side connector 610d and the board side connector 620d are disabled, and a new fixing member 255 is mounted on the mounting base 250 and the connector cover 520 is assembled. A new board case 200 to which the member 510 is attached is attached. By attaching the fixing member 255 and the sealing piece 232 to the base 250, the attachment side member 510 cannot be removed again, and the connection between the cable side connector 610a and the board side connector 620a, the cable When the connection between the side connector 610d and the board side connector 620d is released, the trace can be left. That is, in such a case, the attachment side member 510 and the connector cover 520 can be reused.

  In the present embodiment, the engaging portions 511 and 511 of the attachment side member 510 are elastically deformed outward and engaged with the engaging grooves 514 and 514 formed on the back surface of the substrate case 200. When the attachment member 510 is attached to the substrate case 200 and the substrate case 200 to which the attachment side member 510 is attached is fixed to the attachment base 250 (housing) so as not to be detached, the side piece of the attachment side member 510 510d and 510d are in contact with the inner surfaces of the side walls 250b and 250c of the mounting base 250, and are held between them so that the deformation of the both side pieces 510d and 510d of the mounting side member 510 to the outside is restricted. For example, a part of the attachment-side member is screwed on the back surface of the substrate case 200 or a detachable locking pin. In addition to fixing, when the board case 200 is detachably attached to the housing (mounting base), the screws and the locking pins are hidden so that the board case 200 is attached to the housing. The configuration may be such that the removal of the side member from the substrate case 200 is restricted, and after the substrate case 200 is fixed to the housing in a state where the attachment side member is attached to the substrate case 200, the attachment side member is the substrate case. Any configuration may be adopted as long as the configuration cannot be removed from 200.

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

  30 is an exploded perspective view showing the mounting table 660 and the cover member 680 constituting the connector restricting member 650, and FIG. 31 is a perspective view showing a state in which the cover member 680 is assembled to the mounting table 660. 32A is a cross-sectional view taken along the line E-E in FIG. 30, and FIG. 32B is a cross-sectional view taken along the line F-F in FIG. 31.

  As shown in FIGS. 30 and 31, the connector restricting member 650 includes a mounting table 660 on which the operation unit relay board 110 is mounted and a cover member 680 that covers the mounting table 660 from above, and the mounting table 660. After accommodating the operation unit relay board 110, the cable side connectors 611a and 612g of the corresponding cables 600a and 601g are connected to the board side connectors 621a and 622g of the operation unit relay board 110, and then the cover member 680 is attached to the case. By attaching to the body 610, removal of the cable side connectors 611a and 612g from the board side connectors 621a and 622g is restricted.

  The mounting table 660 is made of a transparent synthetic resin and is formed in a substantially rectangular shape having a larger diameter than the operation unit relay substrate 110. As shown in FIG. 30, board-side connectors 621 a, 622 a, 622 b, 622 c, 622 d to 622 f, 622 g are mounted on the operation unit relay board 110, and both side surfaces on the long side of the mounting table 660, and short The board side connectors 622a, 622b, 622c, and 622d to 622f whose insertion holes open in the horizontal direction with respect to the mounting surface in the operation part relay board 110 when the operation part relay board 110 is placed on one side surface of the side Each of the locking holes 661 having the locking holes 661b is provided via the connection piece 661a so as to protrude outward, avoiding the portion where the 622g is located. On the inner peripheral surface of the locking hole 661b, a pair of locking claws 661c and 661c facing the center are formed at positions facing each other across the center.

  The cover member 680 is made of a transparent synthetic resin and is formed in substantially the same shape as the mounting table 660. On one long side, the cover member 680 is located at a position corresponding to the board-side connector 621a of the operation unit relay board 110. A cover portion 681 that bulges toward the front side at a position corresponding to the board-side connectors 622a and 622b of the operation portion relay board 110 on the other long side. Cover portions 689 that bulge toward the front are formed at positions corresponding to 622c, 622g, and 622d to 622f, respectively.

  On the upper surface 681a of the cover portion 681, a notch 681b for releasing the cable 600a connected to the board side connector 621a, which is narrower than the long side of the cable side connector 611a of the cable 600a, is formed on the outer side surface. Thereby, covering surfaces 681c and 681 are formed on both side ends of the upper surface 681a, respectively.

  The cover portion 688 has notches 682a for releasing the cables 612a and 612b connected to the board side connectors 622a and 622b, and the cover portion 689 has a cable 612c connected to the board side connector 622c. A notch 682b for releasing the cable, a notch 632c for releasing the cable 612g connected to the board side connector 622g, and a notch 682d for releasing the cables 612d to f connected to the board side connectors 622d to f are formed. Has been. In particular, the notch 682c for releasing the cable 612g connected to the board-side connector 622g is formed to be narrower than the length of the long side of the cable 601g, and both ends of the notch 682c are covered from the cover portion 689. Pieces 683 and 683 are respectively provided.

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

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

  Specifically, the locking cylinder 634 of the cover member 680 is fitted into the locking hole 661 b of the corresponding locking hole 661 of the mounting table 660. Then, by pushing the locking cylinder 634 into the locking hole 661b, the locking claw 661c in the locking hole 661b is engaged with the locking hole 684 of the locking cylinder 684. As a result, it becomes impossible to release the engagement between the locking claw 661c and the locking hole 684 from the outside, and as shown in FIG. 31, the mounting table 660 and the cover member 680 are connected to the locking hole. If the part 661 or the locking cylinder 634 is not broken, it is in a state where it is assembled so that it cannot be removed.

  When the mounting table 660 and the cover member 680 are assembled, as shown in FIG. 32A, the upper surfaces of the both ends of the cable side connector 611a connected to the board side connector 621a of the operation unit relay board 110 are the cover members. Covered by the covering portions 681c and 681c of 680, the movement of the cable side connector 611a in the pulling direction from the board side connector 621a is restricted, and the removal of the cable side connector 611a from the board side connector 621a is restricted. ing.

  When the mounting table 660 and the cover member 680 are assembled, as shown in FIG. 32B, the upper surfaces of both ends of the cable side connector 612g connected to the board side connector 622g of the operation unit relay board 110 are covered. 680 covering pieces 683 and 683 are covered, and movement of the cable side connector 612g from the board side connector 622g is restricted, and removal of the cable side connector 612g from the board side connector 622g is restricted. ing.

  Next, the situation when the connection between the cable side connector 611a and the board side connector 621a and the connection between the cable side connector 612g and the board side connector 622g are released will be described.

  In order to release the connection between the cable side connector 611a and the board side connector 621a and the connection between the cable side connector 612g and the board side connector 622g, a connecting piece 684a for connecting the locking cylinder 684 of the cover member 680 with a tool such as a nipper is provided. Break. As a result, the main body of the cover member 680 and the locking cylinder 684 are separated, and the cover member 680 can be removed from the mounting table 660. By removing the cover member 680 from the mounting table 660, the covering portions 681c and 681c. The restriction on the movement of the cable side connector 611a in the unplugging direction is released, and the restriction on the movement of the cable side connector 612g in the unplugging direction by the covering pieces 683 and 683 is also released, so the cable side connector 611a and the board side connector 621a And the connection between the cable-side connector 612g and the board-side connector 622g can be released.

  When the cover member 680 is removed from the mounting table 660, the main body of the cover member 680 and the locking cylinder 684 are broken. Once the cover member 680 is broken, the original state is not obtained, and the separated locking cylinder 684 is removed from the mounting table 660. Therefore, there remains a trace that the connection between the cable-side connector 611a and the board-side connector 621a and the connection between the cable-side connector 612g and the board-side connector 622g are released. It will be.

  Next, the structure of the locking / unlocking device 1200 capable of locking the front door 1a to the housing 1b in the present embodiment will be described with reference to FIG. FIGS. 33A and 33B are schematic views showing the locked state of the front door, and FIG. 33B is a schematic view showing the unlocked state.

  The locking / unlocking device 1200 is provided on the front door 1a side, and a cylinder lock 1203 provided with a key hole 1202a into which a key 1201 owned by an amusement store can be inserted and a rear surface of the cylinder lock 1202 are provided. A linkage member 1203 that is fixed to the rear end of the cylinder shaft 1202a and that rotates around the axis of the cylinder lock 1202 in conjunction with the turning operation of the key 1201; A latching claw 1204 as a latching part up and down is fixed to the front door 1a and a latching member 1206 facing the up and down direction provided with a pivot shaft 1205 that faces the horizontal direction. A fixing member 1207 having a support shaft 1209 that rotatably supports each of 1204, and a lower end is attached to the fixing member 1207 to urge the locking member 1206 downward. A biasing spring 1208, are mainly composed of.

  A locking hole 1210 is formed on a side of the locking member 1206 in the locking member 1206, and the locking release claw 1203 a formed in the linkage member 1203 is locked. A regulating member 1212 that abuts the lower end of the latching claw 1203a and regulates the ascending of the latching member 1206 is fixed below. Further, an insertion hole 1211 is formed above the locked hole 1210 so that the reset claw 1203b formed in the upper part of the linkage member 1203 can be inserted.

  As shown in the AA sectional view of FIG. 33A and the A′-A ′ sectional view of FIG. 33B, the reset switch 23 (see FIG. 33) is provided between the locking member 1206 and the fixing member 1207. 3), the detected piece 1213 is arranged so as to be movable up and down, and the detected piece 1213 is formed with a locked hole 1214 for locking the reset claw 1203b on the side of the insertion hole 1211. In addition, an insertion hole 1215 through which the unlocking claw 1203a can be inserted is formed below.

  On the other hand, the casing 1b is provided with upper and lower locked pieces 1220 to which the upper and lower locking claws 1204 are locked in the closed state of the front door 1a, as shown in FIG. Since the locking member 1206 is always biased downward by the biasing spring 1208, the locking claw 1204 is locked to the locked piece 1220 in the closed state of the front door 1a, and the front door 1a Opening is regulated.

  The cylinder lock 1202 makes the cylinder shaft 1202b non-rotatable when the key 1201 is not inserted from the front keyhole 1202a (locked state), and can rotate the cylinder shaft 1202b when the key 1201 is inserted. It has an internal mechanism.

  Further, in the vicinity of the upper locking claw 1204, a door opening switch for detecting the retracted position retracted from the locking position locked to the locked piece 1220, that is, the locking claw 1204 retracted to the unlocking position. 28 is provided (see FIG. 33B).

  The operation of the locking / unlocking device 1200 configured as described above will be described. First, in the locked state shown in FIG. 33 (a), the unlocking claw 1203a of the linking member 1203 is AA in FIG. 33 (a). As shown in the cross-sectional view, in the locked state where the locking claw 1204 is locked to the locked piece 1220, the locking claw 1204 is located at the retracted position retracted outward from the locked hole 1210. Therefore, in the state where the front door 1a is opened, the locking claw 1204 is urged to the locking position by the urging spring 1208, but the key 1201 must not be inserted into the key hole 1202a when the front door 1a is closed. However, since the ascending of the locking member 1206 is not restricted by the locking release claw 1203a of the linkage member 1203 that cannot be rotated by the cylinder lock 1202, the locking member 1206 can be locked by simply pushing the front door 1a. After the claw 1204 is pushed down by the locked piece 1220, the claw 1204 is returned to the locking position by the urging force of the urging spring 1208 and is locked to the locked piece 1220. That is, the locking operation by the key 1201 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 1203a of the linkage member 1203 that has been made unrotatable by the cylinder lock 1202 is retracted outward from the locked hole 1210. Therefore, the locking release claw 1203a cannot restrict the lifting of the locking member 1206. However, when the locking member 1206 is lifted without the linkage member 1203, the locking The restricting member 1212 raised together with the stop member 1206 comes into contact with the lower end of the unlocking claw 1203a, and the rise is restricted. That is, since the movement of the latching claw 1204 from the latched piece 1220 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 1204 directly in the unlocking direction by moving the locking member 1206 up. In other words, the rotation of the cylinder lock 1202 and the linkage member 1203 based on the key operation by the unlocking (unlocking) key 1201 that can unlock (unlock) the locking claw 1204 (regular unlocking). The locking claw 1204 cannot be moved in the unlocking direction by an unlocking operation (for example, an illegal unlocking operation such as forcibly raising the locking member 1206) that does not depend on the operation). Can be effectively prevented.

  Further, when opening the front door 1a, the key 1201 is inserted into the key hole 1202a and rotated clockwise as shown in FIG. 33 (b), whereby the linkage member 1203 rotates in conjunction with this, The unlocking claw 1203a enters the locked hole 1210 and is locked to the upper edge of the opening of the locked hole 1210 to raise the locking member 1206. As a result, the locking claw 1204 rotates from the locking position to the locking release position, so that the front door 1a can be opened.

  The door opening switch 28 detects that the locking claw 1204 has moved to the locking release position, and a door opening signal is output to an external device. Etc. can be managed.

  In particular, the door opening switch 28 does not detect the movement of the front door 1a, but in the unlocking direction of the locking piece 1204 for locking the front door 1a to the locked piece 1220 of the housing 1b. By detecting the detection of the movement as the 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 1204 is locked to the locked piece 1220, the front door 1a can be opened as compared with 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 opening switch 28 is provided so as to detect the locking piece 1204. However, for example, a locking member 1206 or the like interlocked with the locking operation or the unlocking operation of the locking piece 1204 is provided. You may make it detect, and when the front door 1a is located in a closed position, you may provide so that this front door 1a itself may be detected.

  Further, in this embodiment, the door opening signal is output to the outside based on the detection of the locking piece 1204 in which the door opening switch 28 as the opening detecting means is located at the locking release position (door opening switch 28; on). However, for example, the door opening switch 28 detects the locking piece 1204 positioned at the locking position, and the locking piece 1204 is retracted to the locking release position so that the locking piece 1204 is detected. A door opening signal may be output to the outside based on the fact that the door is not opened (door opening switch 28; off).

  Further, both a locking door release switch for detecting the locking piece 1204 at the locking position and a locking release door opening switch for detecting the locking piece 1204 at the locking release position are provided, and based on the detection status of both switches. A door opening signal may be output to the outside. Further, a main body door opening switch for detecting the closed position or the open position of the front door 1a itself is provided, and a door opening signal is generated based on the detection status of the locking door opening switch, the locking release door opening switch, and the main body door opening switch. It may be output to the outside.

  Further, a door opening signal may be output to the outside based on a plurality of door opening switch detection conditions such as the locking door opening switch, the locking release door opening switch, and the main body door opening switch. Specifically, for example, when the detection pattern of each door opening switch is a normal detection pattern (for example, locking door opening switch; off, locking release door opening switch; on, main body door opening switch; off), the door An opening signal is output to the outside, and the detection pattern of each door opening switch is a detection pattern other than the normal detection pattern, that is, an abnormal detection pattern (for example, a locking door opening switch; on, a locking release door opening switch) On, main body door opening switch; off), the door opening signal should not be output to the outside. Further, when the detection pattern of each door opening switch is the abnormal detection pattern, a door opening signal is not output to the outside, and a notification that each door opening switch is detected in an abnormal pattern (for example, a door opening signal) Output of an error signal or the like that is different from that in FIG.

  The door opening switch 28 may be a push switch having a pressing portion pressed by the locking piece 1204 retracted to the locking release position, or may be an optical sensor or the like, and its type is limited. is not.

  When the key 1201 is inserted into the key hole 1202a and rotated counterclockwise, the linkage member 1203 rotates in conjunction with this, and the reset claw 1203b is locked to the lower opening edge of the locked hole 1214. Thus, the reset piece 1213 is lowered, whereby the lower end of the reset piece 1213 is detected by a reset switch 23 (not shown).

  As described above, in the slot machine 1 according to the present embodiment, the game control accommodated in the board case 200 is provided by attaching the connector restricting member 500a including the attachment side member 510 and the connector cover 520 to the board case 200. The removal of the board-side connector 620a and the cable-side connector 610a from the board is restricted, and in this state, the board case 200 is attached to the mounting base 250 and the fixing member 255 and the sealing piece 232 are fixed to each other. The removal of the connector regulating member 500a from the board 200 is regulated, and the sealing piece 232 of the board case 200 is broken to release the fixation between the board case 200 and the housing (mounting base 250) or the mounting side. If the attachment state of the member 510 or the connector cover 520 is not released, the board side connector A state that can not be pulled out of the cable-side connector 610a from data 620a. That is, the cable-side connector 610a cannot be removed without leaving a trace that the sealing piece 232 is broken or the connection piece 522a is broken. Since it becomes impossible to do so, it becomes possible to surely detect that there is a possibility of fraud.

  Further, when the game control board 40 is replaced together with the board case 200 containing the game control board 40 due to a failure or the like, the sealing piece 232 is broken to fix the board case 200 and the housing (mounting base 250). If released, the connector regulating member 500a can be removed from the board case 200 and the cable side connector 610a can be removed from the board side connector 620a. Therefore, the connector regulating member 500a can be destroyed or the board case 200 can be destroyed. The cable-side connector 610a can be separated from the board-side connector 620a without opening.

  Further, the connector regulating member 500a is composed of the attachment side member 510 and the connector cover 520, and after the attachment side member 510 is attached to the board case 200, the cable side connector 610a is connected to the board side connector 620a, and the board is in that state. The cable-side connector 610a cannot be removed from the board-side connector 620a by being attached to the attachment-side member 510 so as to cover a part of the cable-side connector 620a from above. Is connected to the board-side connector 620a, and then the locking cylinder 522 of the connector cover 520 is fitted into the locking hole 513a of the locking hole 513 of the attachment-side member 510 located around the board-side connector 620a. The connector cover 52 is simply attached to the attachment side member 510. Part of the cable-side connector 610a is covered and the movement of the cable-side connector 610a in the unplugging direction is restricted, so that the assembling work is reduced when the removal of the cable-side connector 610a from the board-side connector 620a is restricted. it can.

  Further, even when the game control board 40 is housed in the board case 200, it is only necessary to connect the cable side connector 610a to the board side connector 620a as it is, and then attach the connector cover 520. In this case, the assembly work can be more effectively reduced when the removal of the cable-side connector 610a from the board-side connector 620a is restricted.

  Further, the connector cover 520 does not cover the entire connection portion between the cable-side connector 610a and the board-side connector 620a, but covers only a part of the cable-side connector 610a in the pulling direction side. Not only can the removal of the connector 610a with respect to the board-side connector 620a be surely restricted, but the amount of material required for manufacturing the connector cover 520 can be reduced.

  Further, since the connector cover 520 is attached to the attachment side member 510 with only one locking cylinder 522, the structure of the connector cover 520 and the attachment side member 510 can be simplified. A plurality of stop cylinders 522 may be provided, and a locking hole 513a may be provided at a corresponding location on the attachment side member 510, and the connector cover 520 may be attached to the attachment side member 510 at a plurality of locations. By doing so, the removal of the cable-side connector 610a from the board-side connector 620a can be more firmly regulated. Furthermore, in this case, it is preferable that the connector cover 520 is attached to the attachment side member 510 at a plurality of locations across the connection portion between the cable side connector 610a and the board side connector 620a. The removal and removal of the side connector 610a with respect to the board side connector 620a can be more firmly regulated.

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

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

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

  Further, since both the attachment side member 510 and the connector cover 520 constituting the connector restricting member 500a are made of a transparent synthetic resin material, the visibility in the board case 200 may be impaired by the connector restricting member 500a. Therefore, there is no problem in monitoring the game control board 40. Further, even if an unauthorized part is attached to the gap between the connector restricting member 500a and the board case 200, it can be easily found.

  In this embodiment, the connector connection between the game control board 40 and the inserted medal sensor 31, that is, the connection between the board side connector 620 a of the game control board 40 and the cable side connector 610 a of the cable 600 a, the cable side of the cable 600 a Regarding the connection between the connector 611a and the board-side connector 621a of the operation unit relay board 110, and the connection between the board-side connector 622g of the operation part relay board 110 and the cable-side connector 612g of the cable 601g, the connection between these connectors is released. The member 500a and the connector restricting member 650 are used for restriction. As a result, one of the connectors between the game control board 40 and the inserted medal sensor 31 is replaced with a connector such as an illegal driving tool and connected to the main control unit 41 of the game control board 40 for illegal actions relating to the progress of the game. Therefore, it is difficult to perform illegal acts such as inputting / outputting various signals, so that illegal business operations can be effectively prevented.

  Further, in order to release the connector connection between the game control board 40 and the inserted medal sensor 31, the sealing piece 232 of the board case 200, the connection piece 522a of the connector cover 520, and the connection piece 684a of the cover member 680 are broken. As a result, when even one connector connection between the game control board 40 and the inserted medal sensor 31 is released, the trace remains and it is extremely difficult to erase the trace. , The above fraud can be more effectively suppressed.

  In this embodiment, there is only one relay board between the game control board 40 and the inserted medal sensor 31. However, when a plurality of relay boards are used, all the connector connections existing between them are disconnected. It is preferable to restrict the removal, and by doing so, one of the connectors between the game control board 40 and the inserted medal sensor 31 is replaced with a connector such as an unauthorized driving instrument, and the game control board 40 is connected. Since it is difficult to perform an illegal act such as causing the main control unit 41 to input / output an illegal signal related to the progress of the game, it is possible to effectively prevent the unauthorized operation.

  Further, in this embodiment, the first electronic components 5, 6, 7, 8, 31, 33L, 33C, 33R, and 35 that input signals to the game control board 40 according to the progress of the game and the progress of the game. Of the second electronic components 32L, 32C, 32R, 34 for which signals are output from the game control board 40 in response to this, a connector restricting member is provided only for the connector connection between the inserted medal sensor 31 and the game control board 40. The release of connection between connectors is regulated. That is, the inserted medal sensor 31 which cannot advance the game without the signal (the bet number cannot be set and the game cannot be started unless the signal from the inserted medal sensor 31 is input) and the game control. The connector restricting member is provided only for the connector connection with the board 40 to restrict the release of the connection between the connectors, and the connection between the connectors is released between the other electronic components and the game control board 40 to drive the instrument. Even if it is replaced with a connector, it will be impossible to automatically advance the game automatically, so that it is possible to prevent fraud with the minimum restrictions, and to disconnect these connectors The number of parts can be reduced.

  In this embodiment, only the connector connection between the inserted medal sensor 31 and the game control board 40 is provided with a connector restricting member to restrict the connection between the connectors, but the start switch 7 and the game control board 40 are not connected. The same effect can be obtained even if a connector restricting member is provided only for connector connection between the connector and the release of the connection between the connectors is restricted. In addition, if the reel is not configured to stop until the reel is operated after the reel starts rotating, only the connector connection between the stop switch 8L, 8C, or 8R and the game control board 40 is restricted. The same effect can be obtained even if a member is provided to restrict the release of the connection between the connectors.

  In the present embodiment, a plurality of signal lines that connect the main control unit 41 and a plurality of electronic components that perform input / output of signals necessary for the progress of the game are connected to the game control board 40, the operation unit relay board 110, and the like. Since the connection between the board side connector 620a of the game control board 40 and the cable side connector 610a, that is, the release of the connection of only one connector connection is restricted. It is possible to restrict the release of the connection between the plurality of signal lines, and it is not necessary to prepare a plurality of parts for restricting the release of the connector connection, and the number of these parts can be reduced.

  Even when a plurality of signal lines that connect the main control unit 41 and a plurality of electronic components that perform input / output of signals necessary for the progress of the game are connected via a plurality of cables, the board-side connector is connected. A plurality of parts are prepared for restricting the release of these connector connections by restricting the release of the connection between the plurality of board-side connectors and the plurality of cable-side connectors with a single part, as well as being arranged in close proximity. There is no need, and the number of these parts can be reduced.

  Further, in this embodiment, the connection between the cable side connector 611a of the cable 600a connecting the game control board 40 and the operation unit relay board 110 and the board side connector 621a of the operation part relay board 110 is released, and the operation unit relay board 110 is connected. Since the release of the connection between the cable-side connector 612g of the cable 601g that connects the inserted medal sensor 31 and the board-side connector 622g of the operation unit relay board 110 is simultaneously restricted by one connector restriction member 650, a plurality of these There is no need to prepare a plurality of parts for restricting the release of the connector connection, and the number of these parts can be reduced.

  Further, in this embodiment, 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, the CPU 41a indicates a power-on command indicating that the special role is elected. When the sub-control unit 91 receives a power-on command indicating that the special role is won, the sub-control unit 91 executes a notification effect indicating that the special role is won, and also receives a winning determination command indicating that the special role is won. Until it is done, that is, until the winning special role wins, it is continuously executed.

  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 role and to avoid the execution of the announcement effect indicating that the special role is won. Thus, when the main control unit 41 is activated, it returns to the state before the power interruption, and from before the power interruption. When the special role is elected, the winning of the special role is always notified.

  On the other hand, it is necessary to turn off the power once to connect unauthorized tools such as driving tools (disconnecting the connector without turning off the power). With the above configuration, the connector is forcibly released. Even if the special tool is won by using a driving tool, it can be easily determined from the outside that the special role is won when the main control unit 41 is restarted. In addition, it is possible to effectively prevent illegal sales such as providing the gaming machine with the slot machine 1 set in a state in which the special role is won using the driving tool at the start of the business of the game shop.

  In addition, the notice effect is continuously executed until a winning judgment command indicating the winning of the special role is received, that is, until the winning special role is won, so that the special role is won, that is, the winning flag of the special role is set. The notification effect will not stop until it is cleared, and it will not be possible to cancel the notification effect while maintaining the special role election by the amusement store. Unauthorized sales such as providing the slot machine 1 set to "" to a player at the start of business at a game shop can be further effectively prevented.

  Further, in this embodiment, 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, the CPU 41a indicates a power-on command indicating that the special role is elected. , And the sub-control unit 91 receives a power-on command indicating that the special role is won, so that the sub-control unit 91 controls the notice display effect indicating that the special role is won, the effect effect LED 52, This is executed by a production device such as the speakers 53 and 54, the reel LED 55, etc. Even if the special role is won illegally, when the main control unit 41 is restarted, the special role is won. The slot machine is set in a state where the special role is won using a driving tool and is provided to the player at the start of the game shop operation. Do It said was an illegal business can be more reliably prevented.

  In this embodiment, the release of the connector connection between the game control board 40 and the effect control board 90 is restricted by the connector restricting member. After the main control unit 41 is activated, the effect control board By connecting 90, it becomes difficult to craft such as not to notify the special role, so that illegal sales by an amusement store can be prevented more reliably. Further, the connector restricting member is configured to be able to restrict the removal of the cable side connector from the board side connector connected to each other, and the connection release restriction that makes the release impossible unless the release restricting part related to the connection with the connector is destroyed. When the state is formed and the connection release restriction state is released, the trace remains so that the release restriction part must be destroyed in order to release the connection between the connectors. Since it is extremely difficult to form the connection release restriction state again after releasing the connection, and it takes time and effort, it is possible to more effectively prevent the fraud.

  In the present embodiment, the electrical connection state between the game control board 40 and the effect control board 90 is monitored during a power failure, and the electrical connection state between the game control board 40 and the effect control board 90 is monitored. Is released, the game control board 40 has a disconnection monitoring IC 50 that stores a disconnection flag indicating that, and the CPU 41a requests the disconnection monitoring IC 50 to check the disconnection flag at the time of activation. When the disconnection flag is stored based on the reply from the accompanying disconnection monitoring IC 50 and the disconnection flag is stored, that is, the electrical connection state between the game control board 40 and the effect control board 90 is released. In such a case, it is determined that the disconnection is abnormal, and an error state due to the disconnection abnormality error is controlled to disable the progress of the game. Since all the areas except for the above area are initialized and cannot be restored to the original state, after the main control unit 41 is activated, the special control board 90 is connected so that the special role is not notified. In this case, since the RAM 41c is initialized and cannot be restored to the original state, illegal sales by the amusement store can be prevented more reliably.

  In this embodiment, the special device winning is notified by the effect device controlled by the sub-control unit 91. However, 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 interruption of power, the credit display 11, the game auxiliary display 12, and the payout display 13 directly controlled by the main control unit 41 may notify the special role. good. In addition, a notification LED for notifying the winning of the special role is provided as an electronic component that is directly controlled by the main control unit 41. When the main control unit 41 is activated, it returns to the state before the power interruption, and the special role is selected before the power interruption. In this case, the notification LED may be used to notify the winning of the special role.

  Further, in this embodiment, the connector restricting member is provided only for the connector connection between the electronic control component (inserted medal sensor 31) that inputs or outputs a signal to the game control board 40 and the game control board 40 as the game progresses. The use of unauthorized devices is also prevented by restricting the release of connections between the connectors, but when the main control unit 41 is activated, it returns to the state before the power interruption, and the special role is elected before the power interruption. In this case, it is possible to prevent the use of a driving tool regardless of whether or not the structure for restricting the insertion / removal between the connectors is made by notifying that effect. By doing so, it is not necessary to change the structure of parts in order to regulate the insertion and removal of connectors, and maintainability in the event of a failure, etc. It can be improved.

  In this embodiment, the disconnection monitoring IC 50 also monitors the electrical connection state between the game control board 40 and the inserted medal sensor 31 at the time of a power failure, and between the game control board 40 and the inserted medal sensor 31. When the electrical connection state is released, a disconnection flag indicating that is stored, and the CPU 41a requests the disconnection monitoring IC 50 to check the disconnection flag at the time of activation, and the disconnection monitoring IC 50 accompanying this is requested. The storage state of the disconnection flag is acquired based on the reply from and when the disconnection flag is stored, that is, when the electrical connection state between the game control board 40 and the inserted medal sensor 31 is released, It is determined that the disconnection is abnormal, and an error state due to the disconnection abnormality error is controlled to disable the progress of the game. There all the area except the area in use is initialized and becomes impossible return to the original state.

  On the other hand, in order to connect an unauthorized device such as a driving device, it is necessary to insert / remove the connector, but even if a special device is selected by using the driving device, the connector must be replaced with a regular connector. Since the disconnection flag is stored in the disconnection monitoring IC 50 and the CPU 41a is activated, all the areas of the RAM 41c other than the area in use by the CPU 41a are initialized. It is possible to effectively prevent illegal sales such as providing a slot machine set in a state in which a special role is won using a driving tool to a player at the start of a game shop business.

  Further, the disconnection monitoring IC 50 monitors the electrical connection state between the game control board 40 and the inserted medal sensor 31 even when energized, and the electrical connection between the game control board 40 and the inserted medal sensor 31. When the state is released, the disconnection flag indicating that is stored, and the CPU 41a periodically checks the storage state of the disconnection flag in the timer interruption process even after the activation, and the disconnection flag is stored. In such a case, it is determined that the disconnection is abnormal, and an error state due to the disconnection abnormality error is controlled to disable the progress of the game, and all areas of the RAM 41c other than the area being used by the CPU 41a are initialized, Since it is impossible to return to the original state, the disconnection monitoring IC 50 can be used even when the connection of the connector is released to replace it with a normal connector without turning off the power. The disconnection flag is stored, and accordingly, an error state due to disconnection abnormality is controlled, and all areas of the RAM 41c other than the area in use by the CPU 41a are initialized. It is possible to more surely prevent illegal sales such as providing a slot machine set in a state where a winning combination is won to a player at the start of a game shop business.

  Also, in this embodiment, once controlled to an error state due to a disconnection abnormality error, 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. That is, not the setting value automatically set by the slot machine with the initialization of the RAM 41c, but the setting value selected and set based on the setting change operation (generally, the setting change operation is an employee of a game shop) Therefore, it is ensured that the game is played based on the setting value selected by the amusement shop side), so that the fairness of the game can be achieved.

  In this embodiment, when the CPU 41a determines that the disconnection is abnormal and controls the error state due to the disconnection abnormality error, all the areas of the RAM 41c other than the area in use by the CPU 41a are initialized. Although the configuration is such that the original state cannot be restored, the RAM 41c is not initialized in the error state due to the disconnection abnormality error, but after that, the RAM 41c is initialized (in this embodiment, the setting change mode is entered). A transition operation corresponds to this, but separately from this, an initialization switch for initializing the RAM 41c by being detected when the power is turned on may be provided, and the initialization operation of the RAM 41c by the initialization switch may be applied. ), The error state may be canceled and the game can be made possible. Even if the special device is illegally set using a special instrument, the disconnection flag is stored in the disconnection monitoring IC 50 and the CPU 41a is activated by releasing the connection of the connector in order to replace it with a regular connector. At this time, since the RAM 41c is initialized and the progress of the game is disabled until the RAM 41c is initialized, the slot machine set in the state where the special role is won using the driving tool is changed to the amusement store. It is possible to effectively prevent illegal sales such as providing to a player at the start of business.

  Further, in this embodiment, the connector restricting member is provided only for the connector connection between the electronic control component (inserted medal sensor 31) that inputs or outputs a signal to the game control board 40 and the game control board 40 as the game progresses. The use of unauthorized devices is also prevented by restricting the release of the connection between the connectors, but the state of electrical connection between the game control board 40 and the inserted medal sensor 31 is monitored, and the game control board When the electrical connection state between 40 and the inserted medal sensor 31 is released, a disconnection flag indicating the fact is stored, and the CPU 41a confirms the storage state of the disconnection flag at the start and after the start. If the disconnection flag is stored, it is determined that the disconnection is abnormal, and the error state due to the disconnection abnormality error is controlled to disable the progress of the game. Initialize all the areas of the M41c area except for the areas that are being used by the CPU 41a, or disable the progress of the game until the RAM 41c is initialized by performing an initialization operation, so that the connectors can be inserted and removed. Regardless of whether or not the structure is restricted, it is possible to prevent the use of a driving tool, so it is possible not to have a structure that restricts the insertion and removal of connectors. In addition to requiring a significant structural change in the parts to regulate, it is possible to improve maintainability in the event of a failure.

  In this embodiment, the disconnection monitoring IC 50 monitors the electrical connection state between the game control board 40 and the inserted medal sensor 31, but signals necessary for the progress of the game are input and output. Electronic components (for example, stop switch 8L, 8C, 8R, etc. in a configuration that does not stop the reel until the reel stop operation is performed after the start of reel rotation). The same effects as described above can be obtained.

  Further, in the present embodiment, the disconnection monitoring IC 50 has an electrical connection between the game control board 40 and an electronic component (inserted medal sensor 31) that inputs or outputs a signal to the game control board 40 as the game progresses. And the game control board 40 between the electronic component (the input medal sensor 31) and the game control board 40 that inputs or outputs a signal to the game control board 40 according to the progress of the game. When the disconnection is determined, the RAM 41c is initialized to prevent illegal sales by the game store. As shown in FIG. 48, the backup power source of the main control unit 41 is connected to the game control board 40. To the game control board 40 and the operation part relay board 110, the operation part relay board 110, the operation part relay board 110 and the inserted medal. Via the cable 601g for wiring connection of the sensor 31 and further turned back by the inserted medal sensor 31, and returned to the game control board 40 again via the cable 601g, the operation part relay board 110, and the cable 600a, and the main control part 41 The connector may be connected between the game control board 40 and the inserted medal sensor 31 while the power supply to the slot machine 1 is cut off. Is released even at one location, the backup power supply line is disconnected, the data in the RAM 41c of the main control unit 41 cannot be retained, and is lost. In other words, when even one connection between the game control board 40 and the inserted medal sensor 31 is released, the backup data held in the RAM 41c of the main control unit 41 is lost. On the other hand, in order to connect an unauthorized device such as a driving device, it is necessary to insert / remove the connector, but even if a special device is selected by using the driving device, the connector must be replaced with a regular connector. Since the data in the RAM 41c is initialized by releasing the connection, the slot machine 1 set in a state in which the special role is elected using the driving tool is provided to the player at the time of starting the business of the game shop. Unauthorized sales such as doing can be prevented.

  Note that when the backup power is returned from the game control board 40 to the game control board 40 via the inserted medal sensor 31 and supplied to the main control unit 41, the connector connection therebetween is released. Although the data in the RAM 41c is lost, an electronic component (for example, a start switch 7 or a reel stop operation is performed after the reel starts rotating) that inputs and outputs signals necessary for the progress of the game. The same effect as described above can be obtained even if the stop switch 8L, 8C, 8R or the like is not used.

  Capacitors and batteries that store backup power are mounted on electronic component mounting boards and relay boards (operation unit relay board 110, etc.) for these electronic parts, which are required to input and output signals necessary for the progress of the game. A backup power supply line from a capacitor or a battery mounted on the mounting board or the relay board is connected to the game control board through a cable together with a signal line of the electronic component and supplied to the main control unit 41. Even in this case, since the data in the RAM 41c is lost when the connector connection between the mounting board or the relay board and the game control board 40 is released, the same effect as described above is obtained. In addition, the game control board 40 can be backed up via a cable from a capacitor or battery mounted on the mounting board or relay board. Therefore, in order to continue supplying the backup power to the main control unit 41 when the cable is disconnected, it is necessary to short-circuit the backup power supply line across the boards. Since it becomes very difficult to release the connector connection in a state in which the backup power supply is continuously supplied, the connection of the driving tool can be effectively prevented.

  Further, in the slot machine 1 of this embodiment, it is determined for each game 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 the value read from the set value work is not 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 at the same time 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. When the value is 1, the abnormal winning determination flag indicating that the winning combination is not won, and the value of the bit assigned to each type of winning combination is 1, that the winning combination has been won. And a winning symbol flag indicating that the winning combination has not won when it is 1, and indicates whether the calculation result is 0, that is, whether the calculation result is 0 or not. It becomes 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. The bit of the winning flag of the winning combination that has been established as in the past is specified, and the value of the specified bit 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 storage work (iwin_flag) 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, 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 of always causing a loss at the time of automatic stop is added, the reel stop control is not complicated accordingly.

  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.

  In addition, after shifting 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 to the automatic stop control is performed. 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 transitioning to automatic stop control without creating a non-winning position table, when the two reels except the last reel stopped, or when transitioning to automatic stop control after two reels stopped 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 where it can be stopped at the earliest stage (a range of less than one frame) at the time when it is determined.

  In this embodiment, the stop control according to the winning flag is based on the stop control table according to the winning flag. However, 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 stop operation is performed or automatic stop control other than the reel to be stopped 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.

  In this embodiment, when a stop operation is performed, the reel stop control table corresponding to all reels, that is, referring to data in which the stop position is determined 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 method 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 for 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 last, and the reel that stops last is due to the stop operation. If there is control by the control method, if the last reel is stopped by the stop operation, the role won 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.

  Further, in a slot machine, the ratio of the stop operation being generally performed in the order of the left reel, the middle reel, and the 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 as viewed from the player side, and the start switch 7 is disposed on the left side of the front door. . 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 such 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 in 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. Although the game is 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. .

  Also, 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 eyes and the reach eyes are invalid, and the reach eyes and the chance eyes are derived even though the reach eyes and the chance eyes are 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.

  Further, the slot machine 1 of the present embodiment has a door opening switch 28 for detecting opening of the front door 1a. When the opening of the front door 1a is detected by the door opening switch 28, a door opening signal is output to the external output. The signal is output to an external device such as a hall computer via the substrate 1100. The parts that control the game, such as the game control board 40, are in the housing 1b, and it is necessary to open the front door 1a in order to perform fraud, but the door is based on the detection of opening of the front door 1a. Since the opening signal is output to the external device, it is possible to detect at an early stage that there is a possibility that an illegal act has been performed. Further, since the backup power is supplied to the door opening switch 28 even in the event of a power failure, the front door 1a can be used even when the power of the slot machine 1 is turned off and no power is supplied, for example, outside business hours. Since the opening of the front door 1a is detected by the door opening switch 28 and the door opening signal is output to the external device, there is a possibility that an illegal act has been performed outside business hours. You can discover that.

  Further, in the slot machine 1 in the present embodiment, when the door opening detection IC 98 provided on the effect control board 90 monitors the detection state of the door opening switch 28, the door opening switch 28 detects the opening of the front door 1a. The door opening history information indicating that the front door 1a has been opened is stored in the storage unit provided inside, and the opening history information stored by the door opening detection IC 98 (the CPU 91a has acquired from the door opening detection IC 98). Information) is displayed on the liquid crystal display 51, and even when the door open signal is not connected to a hall computer or the like outside the slot machine 1, the open state of the front door 1a is confirmed. be able to.

  In addition, the connection between the cable side connectors 1610a to 1610f provided on the cables 1600a to 1600d as the door opening signal cables for outputting the door opening signal and the board side connectors 1620a to 1620f provided on the respective boards is illustrated. The connection restriction control state that makes the release impossible is formed unless the release restriction part related to the connection with the connector is destroyed by the restriction member that does not release the connector connection of the door opening signal cables 1600a to 1600d. This prevents unauthorized actions that prevent the door opening signal from being output to an external device, and when 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, a method for restricting connector removal by attaching the connector restricting members 500a and 500b to the board case 200 is a cable 600a for connecting the game control board 40 and the operation unit relay board 110 and the game control. Although it is applied to the connector connection between the cable 600d for connecting the board 40 and the effect relay board 80 and the game control board 40, it may be applied to other connector connections.

  In the above embodiment, a method for restricting the release of the connection between the connectors is described. For example, an electronic component that inputs and outputs signals necessary for the progress of the game, such as the inserted medal sensor 31 and the start switch 7, It is preferable to attach a covering member that is inaccessible from the outside to the connection part between the electronic component and the cable, and in this way, an electronic component that inputs and outputs signals necessary for the progress of the game It is possible to prevent an unauthorized device such as a driving device from being attached to the connection portion with the cable. In addition, it is preferable to adopt a structure in which a trace remains (such as a structure that cannot be removed unless a part of the covering member is destroyed) when the covering member that covers the connection portion between the electronic component and the cable is removed. By doing so, it becomes possible to leave a trace on which the illegal device is attached, and it is possible to grasp the possibility that there was an illegal act after the fact.

  In the above-described embodiment, the connector restriction members 500a and 500b are configured separately from the board case 200, and the board case 200 is removed from the mounting base 250, whereby the connector restriction members 500a and 500b are removed from the board case 200 and the connector is removed. For example, when the connector restriction members 500a and 500b are once attached to the board case 200, a part of the board case 200 or the connector restriction members 500a and 500b must be destroyed. For example, the connector restriction members 500a and 500b may be removed from the board case 200 so that the restriction on connector removal cannot be released.

  In the embodiment, the connector regulating members 500a and 500b are constituted by the attachment side member 510 and the connector cover 520, and after attaching the attachment side member 510 to the board case 200, the cable side connector is connected to the board side connector. In this state, by attaching the connector cover 520 to the attachment side member 510, the removal of the connector is restricted, but it is integrated from the beginning with the cable side connector connected to the board side connector. The connector restriction members 500a and 500b may be attached to the board case 200 to restrict the connector from being removed.

  In the above-described embodiment, the example in which the connector restricting members 500a and 500b are used as the method for restricting the release of the connection between the board-side connector and the cable-side connector of the board accommodated in the board case has been described. May be.

  A modification of the method for restricting the removal of the cable-side connector from the board-side connector will be described below.

  [Modification 1]

  FIG. 34 is a perspective view showing the structure of the substrate case 700 and the connector cover 710 in the first modification.

  As shown in FIG. 34, the board case 700 in Modification 1 is composed of a lower case 700a that houses the game control board 40 and an upper case 700b that covers the upper part of the lower case 700a. Each of the lower case 700a and the upper case 700b is provided with a corresponding sealing piece (not shown) as in the case of the substrate case 200 of the above-described embodiment. If the sealing piece is not cut by being fixed by the fixing member, the game control board 40 opened and accommodated cannot be taken out.

  In the upper case 700b, an insertion hole 701 for inserting the board-side connector 620a is formed at a position corresponding to the board-side connector 620a of the stored game control board 40. Further, locking pieces 702 and 702 each having a locking hole 703 are erected in the vicinity of both sides of the insertion hole 701 of the upper case 700b.

  The connector cover 710 is formed in a box shape in which the lower surface and the rear surface in the drawing are opened, and has a length that can cover the board-side connector 620a and the locking pieces 702 and 702 with the openings on the lower surface and the rear surface.

  The front surface of the connector cover 710 in the figure relates to positions corresponding to the locking holes 703 and 703 formed in the locking pieces 702 and 702 when the board-side connector 620a and the locking pieces 702 and 702 are covered. Stop holes 711 and 711 are formed, and concave grooves 712 and 712 larger in diameter than the locking holes 711 and 711 are formed in the periphery thereof.

  Thin portions 715 are formed by forming notches 713 and long holes 714 at positions from the center of the locking holes 711 and 711 on the front surface and the upper surface of the connector cover 710 in the drawing.

  Next, a method for restricting the removal of the cable side connector from the board side connector and a method for canceling the cable side connector in Modification 1 will be described with reference to FIGS.

  As shown in FIG. 35, with the cable side connector 610a connected to the board side connector 620a, the connector cover 710 covers the cable side connector 610a and the locking pieces 702, 702 connected to the board side connector 620a. . As a result, the locking holes 711 and 711 of the connector cover 710 and the locking holes 703 and 703 of the locking piece 702 are in communication with each other, and the locking pins 720 are attached to the communicating locking holes 711 and 703. To do.

  The locking pin 720 is a member in which a locking claw 721 whose tip is elastically deformable inward is formed on the head having substantially the same diameter as the concave groove 712. As shown in the enlarged sectional view of FIG. By inserting the locking claw 721 side of the locking pin 720 into the locking hole 711 and the locking hole 703, the locking claw 721 is elastically deformed inward, and the head of the locking pin 720 is formed in the concave groove 712. By inserting until it is filled, the elastic deformation of the locking claw 721 is released, the locking claw 721 engages with the locking piece 702, and the locking pin 720 cannot be removed from the connector cover 710 and the locking piece 703. Accordingly, the connector cover 710 is fixed so as not to be removable from the upper case 700b via the locking piece 702.

  As shown in FIG. 35, the cable-side connector 610a and the locking pieces 702 and 702 connected to the board-side connector 620a are covered by the connector cover 710, and the locking pins 720 are attached to the locking holes 711 and 703. As a result, the cable-side connector 610a connected to the board-side connector 620a is covered with the connector cover 710 and the surface of the upper case 700b, and movement of the cable-side connector 610a with respect to the board-side connector 620a is restricted. Therefore, the removal of the cable side connector 610a with respect to the board side connector 620a is restricted. Further, since the connector cover 710 is fixed so as not to be detached from the upper case 700b via the locking piece 702 by mounting the locking pin 720, the locking piece 702 of the connector cover 710 or the upper case 700b must be destroyed. The connection between the board side connector 620a and the cable side connector 610a cannot be released.

  Also, as shown in FIG. 36, by cutting the thin portion 715 formed on the connector cover 710 with a tool such as a nipper N, the connector cover 710 is connected to the board-side connector 620a as shown in FIG. The covered portion of the cable-side connector 610a is separated from the portions 710 ′ and 710 ′ connected to the locking pieces 702 and 702, and the covering is released to release the connection between the board-side connector 620a and the cable-side connector 610a. It becomes possible. Even in this case, since the portions 710 ′ and 710 ′ of the connector cover 710 connected to the locking pieces 702 and 702 remain fixed to the upper case 700b, the connection between the board side connector 620a and the cable side connector 610a is left. You can leave a trace that has been released.

  In the method of the first modification, the locking pieces 702 and 702 are erected on the upper case 700b. However, as in the above-described embodiment, the attachment pieces are attached to the board case and formed on the attachment side member. A locking member is provided upright near both sides of the insertion hole through which the board-side connector 620a is inserted, and the connector cover 710 is fixed to the locking piece of the attachment-side member to constitute a connector restricting member. In this way, even when the board is exchanged together with the board case, the board case can be opened without breaking the board case and opening it, or breaking the mounting side member or the connector cover 710 and separating them. The connection between the connector 620a and the cable side connector 610a can be released.

  [Modification 2]

  FIG. 38 is a perspective view showing the structure of the substrate case 730 and the connector cover 740 in the second modification.

Each of the lower case 730a and the upper case 730b is provided with a corresponding sealing piece (not shown) as in the case of the substrate case 200 of the above-described embodiment. If the sealing piece is not cut by being fixed by the fixing member, the game control board 40 opened and accommodated cannot be taken out.

  In the upper case 730b, an insertion hole 731 for inserting the board-side connector 620a is formed at a location corresponding to the board-side connector 620a of the stored game control board 40. Further, locking pins 735 and 735 are formed in the vicinity of both sides of the insertion hole 731 of the upper case 730b, and locking pins 735 and 735 each having locking claws 736 and 736 whose tips are elastically deformable inward.

  Further, the connector cover 740 is formed so that the lower surface and the rear surface in the figure are opened, can cover the board-side connector 620a, and has a length longer than the separation width of the locking pins 735 and 735. . Further, attachment surfaces 746 and 746 are formed on part of the lower surface of both ends of the connector cover 740. When the board-side connector 620a is covered on the attachment surfaces 746 and 746, the locking pins 735 and 735 are formed. Slots 747 and 747 are respectively formed at positions corresponding to. Each of the long holes 747 has a long diameter in a direction perpendicular to the locking claws 736 and 736 of the locking pin 735, and the width of the short diameter portion of the long hole 747 is the same as that of the locking claws 736 and 736. It is formed narrower than the distance between the tips.

  Thin portions 745 are formed by forming a notch 743 and a long hole 744 at positions from the center of the long holes 747 and 747 on the front and top surfaces of the connector cover 740 in the drawing.

  Next, with reference to FIGS. 38 to 41, a method for restricting the removal of the cable-side connector from the board-side connector and a method for releasing it will be described.

  As shown in the enlarged cross-sectional view of FIG. 38, with the cable side connector 610a connected to the board side connector 620a, the locking pins 735, 735 of the upper case 730b are connected to both mounting surfaces 746, 746 of the connector cover 740. The formed long holes 747 and 747 are inserted. When the locking pins 735 and 735 are inserted into the long holes 747 and 747, the locking claws 736 and 736 are elastically deformed inward, until the mounting surface 746 of the connector cover 740 and the upper surface of the upper case 730b come into contact with each other. By inserting the locking pins 735 and 735, the elastic deformation of the locking claws 736 and 736 is released, the locking claws 736 and 736 engage with the mounting surface 746, and the locking pins 735 and 735 are connected to the connector cover. The connector cover 740 is fixed to the upper case 730b through the locking pins 735 and 735 so as not to be removed.

The covered portion of the cable-side connector 610a is separated from the portions 740 ′ and 740 ′ connected to the locking pins 735 and 735, and the covering is released to release the connection between the board-side connector 620a and the cable-side connector 610a. It becomes possible.

  As shown in FIG. 41, the removal of the locking piece 740 ′ is performed by rotating the locking piece 740 ′ in the black arrow direction “a” in the drawing so as to align with the longitudinal direction of the long hole 747 (the vertical direction in FIG. 41). . As a result, the engagement between the locking pin 735 and the locking piece 740 'is released. Then, the locking pieces 740 ′ and 740 ′ can be removed from the upper case 730 b by pulling out the locking pieces 740 ′ in the black arrow direction b in the figure. Even in this case, the connector cover 740 is destroyed and cannot be returned to the original state, so that a trace remains that the connection between the board-side connector 620a and the cable-side connector 610a is released.

  In the method of the modification 2, the locking pins 735 and 735 are erected on the upper case 730b. However, as in the above embodiment, the locking pins 735 and 735 are provided on the mounting side member and formed on the mounting side member.

A restricting member may be configured. In this way, even when the board is replaced with the board case, the board case is broken and opened, or the attachment side member or the connector cover 740 is broken and separated. The connection between the board-side connector 620a and the cable-side connector 610a can be released without being released.

  [Modification 3]

  FIG. 42 is a perspective view showing the structure of the substrate case 750 and the connector cover 760 in the third modification.

  As shown in FIG. 42, the board case 750 according to the third modification includes a lower case 750a that houses the game control board 40 and an upper case 750b that covers the upper part of the lower case 750a. Each of the lower case 750a and the upper case 750b is provided with a corresponding sealing piece (not shown) like the substrate case 200 of the above-described embodiment, and the corresponding sealing pieces are connected to each other by a one-way screw or the like. If the sealing piece is not cut by being fixed by the fixing member, the game control board 40 opened and accommodated cannot be taken out.

  In the upper case 750b, an insertion hole 751 for inserting the board-side connector 620a is formed at a location corresponding to the board-side connector 620a of the stored game control board 40. In addition, attachment holes 754 and 754 are formed on the side surface of the upper case 750b located behind the insertion hole 751. A locking piece 752 having a locking hole 753 is provided in the vicinity of the insertion hole 751 of the upper case 750b in the lower case 750a.

  The connector cover 760 is formed so as to open from the lower surface to the rear surface in the drawing, and has a length that can cover the board-side connector 620a. On the rear surface of the connector cover 760 in the figure, when the board-side connector 620a is covered, mounting pieces 764 and 764 having locking claws at the tips project from the rear at positions corresponding to the mounting holes 754 and 754. Has been. Further, on the front surface of the connector cover 760 in the figure, a locking piece 762 having a locking hole 763 is formed at a position corresponding to the locking piece 752 when the board-side connector 620a is covered.

  Next, with reference to FIG. 43, a method for restricting the removal of the cable-side connector from the board-side connector and a method for releasing the same will be described.

  As shown in FIG. 43A, in a state where the cable side connector 610a is connected to the board side connector 620a, the cable side connector 610a connected to the board side connector 620a is covered with the connector cover 760. When the corresponding mounting pieces 764 and 764 of the connector cover 760 are inserted into the mounting holes 754 and 754 of the upper case 750b, the locking claws of the locking pieces 764 and 764 engage with the mounting holes 754 and 754, and the connector cover 760 Is in a state in which it cannot be removed from the upper case 750b. When the connector cover 760 is attached to the upper case 750b in this way, the engagement holes 763 of the engagement pieces 762 of the connector cover 760 and the engagement holes 753 of the engagement pieces 752 of the lower case 750a are in communication with each other. The binding band 769 is attached to the locking hole 763 and the locking hole 753.

  As shown in FIG. 43, the binding band 769 is formed with a label portion 768 to which an ID number or the like for ID management is assigned, an engaging portion 766 in which a locking hole 766a is formed, and a part thereof at a predetermined pitch. And a band portion 767 having a locking projection 767a. The engagement hole 766a is engaged with the locking projection 767a when the band portion 767 is inserted into the locking hole 766a. An engagement claw (not shown) is formed to be stopped. As a result, once the band portion 767 is inserted into the engagement hole 766a, the removal of the band portion 767a in the direction opposite to the direction of insertion through the engagement hole 766a is restricted.

  When the band portion 767 of the binding band 769 is inserted through the engagement hole 766a, the band portion 767a is disengaged from the engagement hole 766a due to the engagement between the locking protrusion 767a of the band portion 767 and the engagement claw of the engagement hole 766a. Since the removal is restricted, the locking piece 762 and the locking piece 752 are fixed. Then, the engagement between the attachment pieces 764 and 764 and the attachment holes 754 and 754 and the connection with the engagement pieces 762 and the engagement pieces 752 by the binding band 769 restrict the movement of the connector cover 760 in the vertical and horizontal directions. Is attached to the substrate case in a non-removable manner with respect to 750.

  As shown in FIG. 43B, in a state where the connector cover 760 is attached to the board case 750, the cable side connector 610a connected to the board side connector 620a is covered with the connector cover 760, and the cable to the board side connector 620a is covered. Since the movement of the side connector 610a in the pulling direction is restricted, the removal of the cable side connector 610a from the board side connector 620a is restricted. Further, the mounting pieces 764 and 764 engage with the mounting holes 754 and 754, and the locking pieces 762 and the locking pieces 763 are fixed so as not to be detached by the binding band 769. Therefore, the substrate is not cut unless the binding band 769 is cut. The connection between the side connector 620a and the cable side connector 610a cannot be released.

  For releasing the connection between the board-side connector 620a and the cable-side connector 610a, for example, by cutting the binding band 769 with a tool such as a nipper, the fixing of the locking piece 762 and the locking piece 752 is released, and the connector Since the cover 760 can be opened upward and the cable-side connector 610a can be moved in the pulling direction, the connection between the board-side connector 620a and the cable-side connector 610a can be released. Even if the binding band 769 is cut and replaced with a new binding band, the ID number or the like is given to the label portion 768 of the binding band 769, so that the connection between the board-side connector 620a and the cable-side connector 610a is established. The released trace can be left.

  In the method of the modification 3, the locking piece 753 protrudes from the lower case 730a. However, the mounting piece is provided with an attachment side member attached to the board case as in the above embodiment, and the attachment side member is provided with the attachment hole and the engagement member. The connector restricting member may be configured by providing a locking piece having a stop hole and fixing the connector cover 760 to the locking piece of the attachment side member. Even when the entire board case is replaced, the board-side connector 620a and the cable-side connector 610a can be disconnected without breaking and opening the board case or forming the binding band 769.

  [Modification 4]

  FIG. 44 is a perspective view showing the structure of the substrate case 770 and the connector cover 780 in the fourth modification.

  As shown in FIG. 44, the board case 770 in Modification 4 is composed of a lower case 770a that houses the game control board 40 and an upper case 770b that covers the upper part of the lower case 770a. Each of the lower case 770a and the upper case 770b is provided with a corresponding sealing piece (not shown) similarly to the substrate case 200 of the above-described embodiment, and the corresponding sealing pieces are connected to each other by a one-way screw or the like. If the sealing piece is not cut by being fixed by the fixing member, the game control board 40 opened and accommodated cannot be taken out.

  In the upper case 770b, an insertion hole 771 for inserting the board-side connector 620a is formed at a position corresponding to the board-side connector 620a of the stored game control board 40. Further, locking pieces 772 and 772 formed with locking holes 773 and 773 project from the front surface of the lower case 770a in the vicinity of the insertion hole 771.

  The connector cover 780 is formed so that a lower surface and a rear surface in the drawing are opened, and has a length capable of covering the board-side connector 620a.

  Locking pieces 782 and 782 project from the front surface of the connector cover 780 in the figure at positions corresponding to the locking pieces 772 and 772 when the board-side connector 620a is covered. The locking pieces 782 and 782 are formed with locking holes 783 and 783 at positions corresponding to the locking holes 773 and 773 formed in the locking pieces 772 and 772. A step portion capable of accommodating a screw head is formed on the upper portion of the locking hole 783.

  Next, with reference to FIGS. 45 to 47, a method for restricting the removal of the cable-side connector from the board-side connector and a method for releasing the same will be described.

  As shown in FIG. 45, the cable-side connector 610a connected to the board-side connector 620a is covered with a connector cover 780 in a state where the cable-side connector 610a is connected to the board-side connector 620a. Then, in a state where the locking holes 783 and 783 of the locking pieces 782 and 782 of the connector cover 780 are in communication with the locking holes 773 and 773 of the locking pieces 772 and 772, any one of these communicating locking holes 783. And, as shown in FIG. 46, the one-way screw P is screwed into the corresponding locking holes 773 and 773 until the head is accommodated in the stepped portion.

  As a result, the locking piece 782 of the connector cover 780 and the locking piece 772 of the lower case 770a are fixed, and the connector cover 780 is fixed to the board case 770 so as not to be detached. In this state, the cable side connector 610a connected to the board side connector 620a is covered with the connector cover 780 and the surface of the upper case 770b, and movement of the cable side connector 610a with respect to the board side connector 620a is restricted. Therefore, the removal of the cable side connector 610a with respect to the board side connector 620a is restricted. Further, since the connector cover 780 is fixed so as not to be detached from the board case 770 by screwing the one-way screw P, the board-side connector 620a and the cable side are not damaged unless the locking piece 772 of the connector cover 780 or the lower case 770a is broken. The connection with the connector 610a cannot be released.

  As shown in FIG. 47, the connector cover 780 is formed by breaking the locking piece 782 fixed to the locking piece 772 of the locking pieces 782 and 782 formed on the connector cover 780 with a tool such as a nipper N. 780 can be removed from the board case 770, and by removing the connector cover 780 from the board case 770, the cable side connector 610a can be moved in the pulling direction, and the connection between the board side connector 620a and the cable side connector 610a can be performed. It becomes possible to cancel. Even in this case, the locking piece 782 broken from the main body of the connector cover 780 remains in a state of being fixed to the locking piece 772, so that the connection between the board side connector 620a and the cable side connector 610a is removed. Can leave.

  The connector cover 780 is formed with a plurality of locking pieces 782 and a plurality of locking pieces 772 corresponding to the lower case 770a, and any one of the plurality of locking pieces 782 is formed. Since the connector cover 780 is fixed to the board case 770 in a non-removable manner only by fixing the locking piece 772 corresponding to one, and the release of the connection between the board side connector 620a and the cable side connector 610a is restricted. Even if the locking piece 782 is broken, the connector cover 780 is removed, and the connection between the board-side connector 620a and the cable-side connector 610a is released, if the unused locking piece 782 remains, the unused engagement By fixing the stopper piece 782 and the corresponding locking piece 772, the removed connector cover 780 cannot be removed again from the board case 770. Fixed, it is possible to regulate the release of the connection between the board-side connector 620a and the cable-side connector 610a. That is, while the unused locking piece 782 remains, the connector cover 780 can be used repeatedly and can be reused while leaving the removed trace.

  In the method of the modified example 4, the locking pieces 772 and 772 protrude from the lower case 770a. However, the mounting piece is attached to the board case as in the above embodiment, and is locked to the mounting side member. By providing a locking piece having a hole and fixing the locking piece of the attachment side member and the locking piece 782 of the connector cover 780, the connector restricting member may be configured. Even when the board is replaced with the board case, the board-side connector 620a and the cable-side connector 610a are disconnected without breaking and opening the board case or breaking the mounting-side member or the connector cover 780 and separating them. can do.

  In the above embodiment, the lower case 201 and the upper case 203 constituting the substrate case 200 are sealed and the substrate case 200 is fixed to the mounting base 250 using a one-way screw. You may perform using other members, such as using a locking pin.

  In the above embodiment, as shown in FIG. 8, 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 the 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), the 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 prize by simply determining whether or not the value is a value other than 1 or not.

  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. 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.
