When this is done, the rotation of the reels corresponding to the stop switches 8L, 8C, 8R is stopped, and the symbols are stopped and displayed. The maximum stop delay time from the operation of the stop switches 8L, 8C, 8R to the stop of the rotation of the corresponding reels 2L, 2C, 2R is 190 ms (milliseconds).

  The reels 2L, 2C and 2R rotate 80 times per minute, and 80 × 21 (the number of symbols per reel) = 1680 frames, so the maximum of 4 symbols is drawn in 190 ms. Will be able to. In other words, the symbols that can be selected as the stop symbols are the symbols that are displayed when the stop switches 8L, 8C, and 8R are operated, and the symbols that are four frames ahead of them, for a total of five symbols.

  For this reason, for example, when any one of the stop switches 8L, 8C, 8R is operated and the symbol displayed on the lower stage of the reel corresponding to the stop switch is used as a reference, the symbol from the symbol to four frames ahead is used. Since the symbols can be displayed in the lower row, in each of the reels 2L, 2C, 2R, when any one of the stop switches 8L, 8R is operated, the symbol displayed in the middle row of the reel corresponding to the stop switch. The symbols arranged within 5 frames including can be displayed on the winning line.

  Hereinafter, the reels 2L, 2C, and 2R may be simply referred to as reels unless it is necessary to distinguish between them. Further, the reel 2L may be referred to as a left reel, the reel 2C as a middle reel, and the reel 2R as a right reel. Further, an operation for stopping the reels 2L, 2C, 2R by operating the stop switches 8L, 8C, 8R may be referred to as a stop operation.

  FIG. 5 shows a configuration example of the main control unit 41 mounted on the game control board 40. The main control unit 41 is a one-chip microcomputer, and includes an external bus interface 501, a clock circuit 502, a verification block 503, a specific information storage circuit 504, an arithmetic circuit 505, a reset / interrupt controller 506, CPU (Central Processing Unit) 41a, ROM (Read Only Memory) 41b, RAM (Random Access Memory) 41c, free-run counter circuit 507, random number circuits 508a and 508b, timer circuit 509, interrupt controller 510 A parallel input port 511, a serial communication circuit 512, a parallel output port 513, and an address decoding circuit 514.

  The reset / interrupt controller 506 is for controlling various resets and interrupt requests generated inside or outside the main control unit 41. The reset / interrupt controller 506 includes an out-of-designated area prohibition (IAT) circuit 506a and a watchdog timer (WDT) 506b. The IAT circuit 506a is a circuit that monitors whether the user program is correctly executed in the designated area, and has a function of outputting an IAT generation signal when it is detected that the user program is executed outside the designated area. The watchdog timer 506b has a function of generating a timeout signal for each set period.

  The external bus interface 501 is a bus interface having an interface function between an external bus and an internal bus of a chip constituting the main control unit 41, an address bus, a data bus, and a direction control function of each control signal. The clock circuit 502 is a circuit that generates the internal system clock SCLK by, for example, dividing the control clock CCLK by two. The verification block 503 is connected to an external verification machine and has a function of performing chip verification. The unique information storage circuit 504 is a circuit that stores a plurality of types of unique information that is internal information of the main control unit 41. The arithmetic circuit 505 is a circuit that performs multiplication and division.

  The CPU 41a is a control CPU that executes game control in the slot machine 1 by executing a user program (game control processing program for game control) based on the control code read from the ROM 41b. When such game control is executed, the CPU 41a reads fixed data from the ROM 41b, the variable data writing operation in which the CPU 41a writes various fluctuation data to the RAM 41c and temporarily stores them, and the CPU 41a is temporarily stored in the RAM 41c. A variable data reading operation for reading out various variable data being received, a receiving operation in which the CPU 41a receives input of various signals from the outside of the main control unit 41 via the external bus interface 501, the parallel input port 511, the serial communication circuit 512, etc. However, a transmission operation for outputting various signals to the outside of the main control unit 41 via the external bus interface 501, the serial communication circuit 512, the parallel output port 513, and the like is also performed.

  The ROM 41b stores a control code indicating a user program (game control processing program for game control), fixed data, and the like. The RAM 41c provides a work area for game control. Here, at least a part of the RAM 41c may be a backup RAM backed up by a backup power source. That is, even if the power supply to the slot machine 1 is stopped, at least a part of the contents of the RAM 41c is stored for a predetermined period.

  As the free-run counter circuit 507, an 8-bit free-run counter is mounted. The random number circuits 508a and 508b are circuits that generate numerical data that is a random value having a predetermined update range, such as an 8-bit random number or a 16-bit random number. In this embodiment, the hardware random number generated by the 16-bit random number circuit 508b among the random number circuits 508a and 508b is used as a random number for internal lottery described later. The timer circuit 509 is a 16-bit programmable timer, counts down the set timer value based on the input of the control clock CCLK, and outputs an interrupt request signal to the interrupt controller when reaching 0000H. In this embodiment, the timer circuit 509 can be used to perform periodic interrupt requests and time measurement.

  The interrupt controller 510 is a circuit that controls external interrupt requests from interrupt terminals and interrupt requests from built-in peripheral circuits (for example, serial communication circuit 512, random number circuits 508a and 508b, timer circuit 509). . The parallel input port 511 incorporates an 8-bit wide input-only port. Also, the parallel output port 513 provided in the main control unit 41 shown in FIG. 4 incorporates an output-only port having an 11-bit width. The serial communication circuit 512 is a circuit that performs asynchronous serial communication in input / output with respect to the outside.

  The address decoding circuit 514 is a circuit for decoding each functional block in the main control unit 41 and a chip select signal that is a decoding signal for an external device. In response to the chip select signal, the internal circuit of the main control unit 41 or the external device serving as a peripheral device is selectively operated effectively and can be accessed from the CPU 41a.

  For example, when the main control unit 41 accesses an area of the storage area of the ROM 41b where no program or the like is stored, the main control section 41 accesses an area of the storage area of the RAM 41c where access is prohibited. In other words, when an access to a memory area that is not accessed in normal operation is made, an illegal access reset is generated to disable the progress of the game. Even if an unauthorized program is stored in an area unrelated to the above, an unused area of the RAM 41c, etc., it is possible to prevent the unauthorized program from being executed.

  The main control unit 41 is activated when an internal or external reset occurs. At this time, the value assigned to the ROM 41b and set in the vector table in which the start address of the interrupt process is set. Is a value indicating unused or a value indicating the area where the program etc. is actually stored, and if it is not any value, it will not start, It is possible to prevent in advance the processing that was not originally intended due to the occurrence or the like.

  The main control unit 41 transmits various commands to the sub control unit 91 via the parallel output port 513. A command transmitted from the main control unit 41 to the sub control unit 91 is sent in only one direction, and no command is sent from the sub control unit 91 toward the main control unit 41. In this embodiment, the command is transmitted to the sub-control unit 91 via the parallel output port 513, that is, the command is transmitted as a parallel signal, but via the serial communication circuit 512. A configuration in which a command is transmitted to the sub-control unit 91, that is, a configuration in which the command is transmitted as a serial signal may be employed.

  The main control unit 41 also receives detection states of various switches connected to the game control board 40 from the parallel input port 511. The main control unit 41 executes main processing that shifts in stages according to the detection states of various switches input from the parallel input port 511. Also, the main control unit 41 can execute the interrupt process by interrupting the main process when an interrupt occurs. In the present embodiment, a timer interrupt process (main) is executed every time a time-out occurs in the timer circuit 509, that is, every fixed time interval (about 0.56 ms in the present embodiment). In addition, the main control unit 41 is set to automatically prohibit other interrupts during execution of the interrupt process, and when a plurality of interrupts occur at the same time, a predetermined order is set. The interrupt to be executed with priority is set by. If another interrupt factor occurs during the execution of the interrupt process and the interrupt factor continues even after the interrupt process ends, the interrupt will occur when the interrupt process ends. The prohibition is automatically released and a new interrupt is generated at that time. Note that other interrupts are set to be automatically disabled during the execution of interrupt processing, and interrupt processing is not automatically canceled when interrupt processing is completed. Other interrupts may be prohibited by the program at the start, and the interrupt prohibition may be canceled by the program at the end of the interrupt process.

  The main control unit 41 repeatedly loops the process according to the control state until the detection state of the various switches connected to the game control board 40 changes as the main process, and changes the detection state of the various switches. Execute a process that moves in stages. Further, the main control unit 41 executes a timer interrupt process (main) at regular time intervals (about 0.56 ms in this embodiment). Note that the execution interval of the timer interrupt process (main) is set to a time longer than the sum of the time taken to repeat the process repeated in accordance with the control state in the main process and the execution time of the timer interrupt process (main) Therefore, the process that is repeated according to the control state between the current and next timer interrupt processes (main) is completed at least once.

  An effect switch 56 is connected to the effect control board 90, and a detection signal of the effect switch 56 is input. In addition, presentation devices such as a liquid crystal display 51, presentation effect LEDs 52, speakers 53 and 54, and reel LEDs 55 are connected, and these presentation devices are controlled by a later-described sub-control unit 91 mounted on the presentation control board 90. It is driven based on this. In this embodiment, the sub-control unit 91 mounted on the effect control board 90 controls the output of the effect devices such as the liquid crystal display 51, effect effect LED 52, speakers 53 and 54, and reel LED 55. However, in addition to the sub-control unit 91, an output control unit that directly controls the output of the effect device is mounted on the effect control board 90 or another board, and the sub-control unit 91 is based on a command from the main control unit 41. The output control unit may determine the output pattern of the effect device, and the output control unit may control the output of the effect device based on the output pattern determined by the sub control unit 91. In such a configuration, the sub control unit 91 and the output control may be performed. The output control of the rendering device is performed by both of the units. Further, in the present embodiment, the liquid crystal display 51, the effect effect LED 52, the speakers 53 and 54, and the reel LED 55 are exemplified as the effect device, but the effect device is not limited to these, for example, a mechanically driven display. A device or a mechanically driven item may be applied as the effect device.

  The effect control board 90 is composed of a microcomputer having a sub CPU 91a, ROM 91b, RAM 91c, and I / O port 91d, and a sub control unit 91 for controlling the effect, and a liquid crystal display 51 connected to the effect control board 90. A display control circuit 92 for performing display control, an effect effect LED 52, an LED drive circuit 93 for controlling drive of the reel LED 55, a sound output circuit 94 for controlling sound output from the speakers 53, 54, A reset circuit 95 for providing a reset signal to the sub CPU 91a when an initialization command from the sub CPU 91a is not input for a certain period of time; a switch detection circuit 96 for detecting a detection signal input from switches connected to the effect control board 90; A clock device 97 for outputting time information including date information and time information; A power interruption detection circuit 98 that monitors the power supply voltage supplied to the lot machine 1 and outputs a voltage drop signal indicating that to the sub CPU 91a when a voltage drop is detected, and other circuits are mounted. Has been.

  Sub CPU91a receives the command transmitted from game control board 40, performs various control for performing an effect, and controls each part of the control circuit mounted in effect control board 90 directly or indirectly. .

  The reset circuit 95 has a lower voltage for releasing the reset signal than the reset circuit 49 that gives the system reset signal to the main control unit 41 in the game control board 40. When the power is turned on, the sub control unit 91 It starts at an earlier stage than the unit 41. On the other hand, the power interruption detection circuit 98 has a voltage that outputs a voltage drop signal lower than the power interruption detection circuit 48 that outputs a voltage drop signal to the main control unit 41 in the game control board 40. The sub control unit 91 detects a power failure at a later stage than the main control unit 41, and performs a power interruption process (sub) described later.

  Similar to the main control unit 41, the sub control unit 91 has an interrupt function, generates an interrupt when receiving a command from the main control unit 41, and acquires a command transmitted from the main control unit 41. Execute command reception interrupt processing to be stored in the buffer. Further, the sub control unit 91 executes an interrupt process (sub), which will be described later, by generating an interrupt every time the input number of system clocks reaches a certain number, that is, every certain time interval (about 2 ms). Also, unlike the main control unit 41, the sub control unit 91 interrupts the process even when the timer interrupt process (sub) is being executed when an interrupt is generated based on the reception of the command. The command reception interrupt process is executed at the same time, and the command reception interrupt process is executed with the highest priority even if interrupts that trigger the timer interrupt process (sub) occur at the same time. The sub-control unit 91 is also supplied with backup power at the time of a power failure, and the data stored in the RAM 91c is held while the backup power is supplied.

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

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

  When the setting key switch 37 is turned on and the power is turned on, the door opening detection switch 25 detects that the front door 1b has been opened, and shifts to the setting change state. In addition, by adopting such a configuration, it is possible to prevent the setting change from being illegally performed when the front door 1b is not opened. Further, in the configuration that shifts to the setting change state on the condition that the detection corresponding to the opening of the front door 1b is performed, the door opening detection switch 25 supports the opening of the front door 1b after shifting to the setting change state. Even if the detection is not detected, it is preferable to maintain the setting change state. Thus, even if the front door 1b is temporarily closed during the setting change, an operation for shifting to the setting change state is performed again. This is not necessary, and the setting change operation is not complicated. Further, after the transition to the setting change state, when the setting value is determined by operating the start switch 7 and then the setting key switch 37 is turned off, the door opening detection switch 25 detects that the front door 1b is opened. On the condition that the setting change state is terminated, it may be configured to shift to a state in which the game can proceed. Even in such a configuration, the front door 1b is not opened in an unauthorized manner. It is possible to prevent the setting from being changed.

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

  After the game, when the setting key switch 37 is turned on with no bet number set, the door opening detection switch 25 detects that the front door 1b has been opened. It is good also as a structure which shifts to a setting confirmation state as conditions, and it can prevent that a setting value is confirmed illegally in the state where the front door 1b is not open | released by setting it as such a structure. In addition, in the configuration that shifts to the setting confirmation state on the condition that the detection corresponding to the opening of the front door 1b is performed, the door opening detection switch 25 supports the opening of the front door 1b after the transition to the setting confirmation state. It is preferable to maintain the setting confirmation state even if the detection to be performed is not performed. Thus, even if the front door 1b is temporarily closed during the setting confirmation, an operation for shifting to the setting confirmation state again is performed. This is not necessary and the setting confirmation operation is not complicated. In addition, after shifting to the setting confirmation state, when the set key switch 37 is turned off after the start switch 7 is operated and the set value is confirmed, the door opening detection switch 25 detects that the front door 1b is opened. On the condition that the setting confirmation state is terminated, it may be configured to return to a state in which the game can proceed, and even in such a configuration, the front door 1b is not opened in an unauthorized manner. It is possible to prevent the setting value from being confirmed.

  In the slot machine 1 of the present embodiment, the main control unit 41 determines whether or not the voltage drop signal from the power interruption detection circuit 48 is detected every time the timer interruption process (main) is executed. When the determination process is performed and it is determined that the voltage drop signal is detected in the power failure determination process, a power interruption process (main) for setting data for determining whether or not the data in the RAM 41c is normal at the next return is performed. Run.

  Then, the main control unit 41 returns the processing state of the main control unit 41 to the state before the power interruption based on the data stored in the RAM 41c on the condition that the data in the RAM 41c is normal at the time of activation. However, if the RAM 41c data is not normal, it is determined that the RAM is abnormal, and the RAM abnormal error code is set in the register to control the RAM abnormal error state, thereby disabling the progress of the game.

  The error state shifts to a normal error state that is canceled by a reset operation (operation of the reset / setting switch 38 or the reset switch 23) and the setting change state described above, and is canceled until a new setting value is set. Special error status with no error, the RAM abnormal error status is a special error status, and once it is controlled to the RAM abnormal error status, it shifts to the setting change status and is released until a new set value is set. It will not be done.

  Further, the sub control unit 91 also determines whether or not the voltage drop signal from the power interruption detection circuit 98 is detected in the timer interruption process (sub), and when it is determined that the voltage drop signal is detected, A power interruption process (sub) for setting data for determining whether or not the data in the RAM 91c is normal at the next return is executed.

  Then, the sub-control unit 91 returns the processing state of the sub-control unit 91 to the state before the power interruption based on the data stored in the RAM 91c on the condition that the data of the RAM 91c is normal at the time of activation. However, if the data in the RAM 91c is not normal, it is determined that the RAM is abnormal, and the RAM 91c is initialized. In this case, unlike the main control unit 41, only the RAM 91c is initialized, and the performance is not disabled.

  In addition, even when it is determined that the data in the RAM 91c is normal at the time of activation, the sub control unit 91 activates when receiving a setting command (described later) indicating that the setting change state has been entered from the main control unit 41. Even when a later-described return command or setting command indicating that the control state of the main control unit 41 has returned is not received even after a certain period of time has elapsed, the RAM 91c is initialized. In this case, the execution of the performance is not disabled only by initializing the RAM 91c.

  Next, initialization of the RAM 41c of the main control unit 41 will be described. The usable area in the storage area of the RAM 41c of the main control unit 41 is divided into a game RAM area, an unused area 4, and a non-game RAM area. Further, the game RAM area is divided into a special work, an important work, a general work, an unused area 3 and a game stack area. The special work is a work that stores data that is not initialized even if the setting value is changed, and stores software random numbers, setting values, data indicating a gaming state, and the like. The important work is a work in which data which is inconvenient if it is initialized at the end of a specific gaming state (RB, BB) is stored. The display data of the LED, the input / output data of the input port, the output port, the game time A time counter and the like are stored. The general work is a work that stores data that can be initialized at the end of a specific gaming state, and stores stop symbols, the number of medals to be paid out, and the like. The unused area 3 is a work that is not used by any program. The game stack area is an area in which data saved from a register of the main control unit 41 during execution of a game program to be described later is stored.

  In the present embodiment, when the data in the RAM 41c is destroyed when the setting key switch 37 is turned on and the data in the RAM 41c is destroyed, the data in the RAM 41c is restored when the setting key switch 37 is turned on. Each of the initial conditions is established when the five initialization conditions are satisfied, that is, when the setting change state is terminated, when a specific game state (RB, BB) is terminated, or when one game is terminated. Five types of initialization are performed in different areas to be initialized according to the initialization conditions.

  Initialization 0 is initialization that is performed when data in the RAM 41c is destroyed when the setting key switch 37 is turned on. In initialization 0, all the usable areas are initialized. . Initialization 1 is an initialization performed when the data in the RAM 41c is not destroyed at the time of activation with the setting key switch 37 turned on. In the initialization 1, an area other than the special work in the game RAM area, non All areas of the game RAM area are initialized. Initialization 2 is an initialization that is performed after the setting change state is ended by activation with the setting key switch 37 turned on. In the initialization 2, a special work and a game stack area (in use) in the game RAM area. Areas other than) are initialized. Initialization 3 is initialization performed at the end of a specific gaming state. In initialization 3, the general work, the unused area 3 and the game stack area (unused) in the game RAM area are initialized. Initialization 4 is initialization performed at the end of one game. In initialization 4, the unused area 3 and the game stack area (unused) of the game RAM area are initialized. It should be noted that the storage area for the data indicating the set value and the game state is allocated to the special work, and when the data in the RAM 41c is not destroyed when the setting key switch 37 is turned on, that is, the data in the RAM 41c. When the game is normal and the setting is changed, data indicating the setting value and the gaming state is held. In addition, a storage area for a timer counter, which will be described later, is allocated to an important work and is retained without being initialized at the end of the game or at the end of a specific gaming state.

  Further, the main control unit 41 of the present embodiment, when performing the above-described initialization, designates a start address and an end address as the initialization target RAM address, so that one byte from the designated start address. After overwriting the data with 0, calculate the logical sum of the 1-byte data, and if the calculation result is 0, repeat the process of moving to the next address until the specified end address is reached. Initialize the RAM area in the specified address range.

  When the main control unit 41 in the present embodiment is activated due to the occurrence of a reset, the main control unit 41 performs setting at the time of activation. In the startup setting, a status flag included in the main control unit 41 is initialized. The status flag is data that holds the state of the operation result and execution result of the instruction, and particularly includes an interrupt master permission flag for setting interrupt prohibition / permission. Since the initial value of the interrupt master permission flag is a value indicating prohibition of interrupt, the main control unit 41 is started in a state where interrupt is prohibited. Then, after setting various functions with reference to the HW parameters described later, when a reset occurs according to the program stored in the program / data area, it starts in an interrupt-disabled state and then executes first Start the initial setting process.

  In the initial setting process, the main control unit 41 first sets interrupts to be prohibited, and then determines whether or not the setting key switch 37 is on at the time of activation, and the setting key switch 37 is on at the time of activation. When it is determined that the state is in the state, the process proceeds to the setting change process, and the RAM 41c is initialized at the start of the setting change process. At this time, if the data in the RAM 41c is normal, a part of the control state (setting value, gaming state, etc.) before the change is changed after the setting change by holding the special work and initializing other areas. On the other hand, if the data in the RAM 41c is not normal, the abnormality in the data in the RAM 41c can be surely solved by initializing all the usable areas including the special work. It has become.

  After initialization of the RAM 41c, the interrupt is set to be permitted, the set value is updated by 1 in the range of 1 to 6 every time the reset / setting switch 38 is operated, and after the start switch 7 is detected to be on, The setting value when the setting key switch 37 is detected to be on is stored in the RAM 41c, and the setting change process is terminated.

  As described above, the main control unit 41 starts with the interrupt master permission flag indicating that the interrupt is prohibited and is disabled, and in the initial setting process after the start, Since the initial setting process is executed after the interruption is set to be prohibited, it is possible to prevent an unintended interruption from occurring.

  Moreover, the main control part 41 performs the main process which processes in steps according to progress of a game for every game unit after completion | finish of a setting change process. In the main process, the RAM 41c is initialized for each game unit, and the RAM 41c is also initialized at the end of the setting change process. After the setting change process, the main process starts from the stage before the process of initializing the RAM 41c in the main process. The initialization of the RAM 41c after the setting change process is completed and the game unit It is possible to perform initialization of the RAM 41c for each process by common processing.

  In the slot machine 1 of the present embodiment, a specified number of bets that can be set according to the gaming state (RT0 to RT4, RB) (in this embodiment, 3 for RT0-4 and 2 for RB) is determined. Thus, the game can be started on condition that a prescribed number of bets determined according to the gaming state are set. In the present embodiment, the winning line LN is activated when a specified number of bets according to the gaming state are set.

  In this embodiment, when all the reels 2L, 2C, 2R are stopped, the activated pay line is activated (in the present embodiment, all the pay lines are always activated. A winning combination is obtained when a combination of symbols called “combinations” is arranged on the winning line. The combination may be a combination of the same symbols or a combination including different symbols.

  The type of winning combination is determined according to the game state, but it can be roughly divided into a small role with payout of medals and a replay that can start the next game without the need to set the number of bets. There are a game combination and a special combination with a transition to a game state advantageous to the player. Below, a small role and a re-playing role are collectively called a general role. In order for winning of each combination determined according to the gaming state to occur, it is necessary to win an internal lottery to be described later and set a winning flag of the combination in the RAM 41c. Of these winning flags, the winning flags for the small role and the replaying role are valid only in the game in which the flag is set, and are invalid in the next game. It is valid until a combination of combinations permitted by the flag is completed, and is invalid in a game having a combination of combinations permitted. In other words, once the special combination winning flag is won, even if the combination of the combinations permitted by the flag cannot be made, the winning flag is not invalidated and is carried over to the next game. It becomes.

  Hereinafter, the internal lottery of the present embodiment will be described. In the internal lottery, whether or not the main control unit 41 allows the winning of each combination described above before the display results of all the reels 2L, 2C, and 2R are derived (specifically, the start switch 7 At the time of detection). In the internal lottery, first, a random value for internal lottery (an integer from 0 to 65535) is acquired when the start switch 7 is detected. Specifically, the value generated by the random number circuit 508b and stored in the random number value register of the random number circuit 508b is set as the lottery work assigned to the RAM 41c. And, for each combination determined according to the gaming state, according to the numerical data stored in the lottery work and the number of determination values of each combination determined according to the current gaming state, the number of bets and the set value A determination is made as to whether or not winning is permitted.

  In the internal lottery, the number of judgment values determined in accordance with the internal lottery target, the current gaming state, and the set value are sequentially assigned to the random number for internal lottery (numerical data stored in the lottery work). When the result of addition overflows, it is determined that the winning combination is won. For this reason, a winning combination will be won with a probability (number of determination values / 65536) according to the number of determination values.

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

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

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

  In this embodiment, if any of the winning combinations is won, when the stop operation is performed, the winning combination can be stopped on the winning line within a drawing range of up to four frames. If possible, control is performed to align and stop, and the winning combination that has not been won is controlled to be stopped without being aligned in the drawing range of a maximum of 4 frames. When a special role and a small role are elected at the same time, such as when a special role is elected while the special role has been carried over from before the previous game, the maximum on the winning line when the stop operation is performed If it is possible to align and stop the winning roles in the 4-frame pull-in range, control will be performed to align them and stop them, and the winning roles will be selected on the winning line within the maximum 4-frame pull-in range. If it is not possible to withdraw, if a special role that has been elected within the draw range of up to 4 frames can be aligned and stopped on the winning line, it will be controlled and stopped. Control to stop without aligning in the drawing range of 4 frames will be performed. That is, in such a case, priority is given to the control for aligning the small combination on the winning line over the special combination, and the special combination can be won only when the small combination cannot be drawn. In the case where a special combination and a small combination can be withdrawn at the same time, only the small combination is drawn, and the small combination is not aligned on the winning line at the same time as the special combination. Also, when a special role and a small role are elected at the same time, priority is given to the control of aligning the special role on the winning line over the small role, and only when the special role cannot be drawn, the small role is placed on the winning line. You may perform control to align.

  Also, in this embodiment, when the special role and the replaying role are won at the same time, such as when the replaying role is won while the special role has been carried over from before the previous game, the stop operation is performed. In this case, the 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 4 frames. In this case, the symbols constituting the re-gamer or the symbols constituting the re-gamer to be simultaneously elected are arranged at intervals of 5 symbols or less, that is, within 4 frames, for any of the reels 2L, 2C, and 2R. Since it can always be stopped at any position within the 4-frame pull-in range, if the special combination and the re-playing combination are elected at the same time, the timing of the operation of the stop switches 8L, 8C, 8R by the player Without fail, the re-playing role will always be won. That is, in such a case, the control for aligning the re-games on the winning line has priority over the special game, and the re-games will always win. In the case where the special combination and the re-playing combination can be withdrawn at the same time, only the re-playing combination is drawn in and the special combination is not arranged on the winning line at the same time as the re-playing combination.

  In this embodiment, the reel stop control is performed by using a stop control table that can specify the number of sliding frames for each timing at which the stop operation is performed. A configuration that performs stop control by specifying the stop position from the table and stopping the reel at the specified stop position, and searching for a stop position that can be stopped when the stop operation is performed without using the stop control table or the stop position table. A configuration that performs stop control that identifies and stops the reel at the specified stop position, stop control using the stop control table, stop control using the stop position table, and can be stopped without using the stop control table or the stop position table A configuration that uses stop control by searching and specifying the stop position together, and a configuration that performs stop control by partially changing the stop control table and stop position table. It may be.

  In the present embodiment, the main control unit 41 measures the game time, which is the time elapsed from the start of the reel rotation every time the reel starts rotating after the game starts. After a game is over, when a specified number of bets are set by inserting medals, etc., and the game start operation is enabled, the reel start of the previous game is started. If the game time that has started counting from the time is more than the specified time (4.1 seconds in this embodiment), that is, if the specified time has elapsed since the reel rotation start time of the previous game, no wait is generated. At that time, the reel for the game in the game is started to rotate. On the other hand, after the end of one game, when a predetermined number of bets are set by inserting medals, etc., and when the game start operation is enabled, the reel rotation of the previous game is started. If the game time that started timing from the time is less than the specified time, that is, if the specified time has not elapsed since the start of reel rotation of the previous game, a wait is generated and the reel starts rotating at that time. First, it waits until the game time that has started timing from the reel rotation start time of the previous game reaches the specified time, and starts rotating the reel when it reaches the specified time.

  In the present embodiment, the main control unit 41 performs control to output an external output signal indicating a gaming state, an error occurrence state, and the like. These external output signals are output to a hall device such as a hall computer via the information output terminal board of the game shop (hall) where the external output board 1000 and the slot machine 1 are installed.

  The main control unit 41 has a medal IN signal indicating the number of medals used for setting the number of bets, a medal OUT signal indicating the number of medals awarded to the player due to the occurrence of winning, and the gaming state is RB (regular bonus). An RB signal indicating that the game state is BB (big bonus), an AT signal indicating the start of AT (assist time), a door opening signal indicating that the front door 1b is open, A setting change signal indicating that the mode is changed to a setting change mode, which will be described later, an insertion error signal indicating an abnormality of the medal selector 29, and a payout error signal indicating an abnormality of the hopper unit 34 are output.

  The external output board 1000 is provided with a relay circuit, a parallel / serial conversion circuit, a terminal for each output signal, and a connector to be electrically connected to the circuit of the information providing terminal board. Of the signals output from the game control board 40, the medal IN signal, the medal OUT signal, the RB signal, the BB signal, and the AT signal are directly output as pulse signals to the information providing terminal board via the relay circuit. . On the other hand, the door opening signal, setting change signal, input error signal, and payout error signal are converted into security signals, which are serial signals that can be individually identified by the parallel-serial conversion circuit, and information is provided. Output to the terminal board.

  Next, commands that the main control unit 41 transmits to the sub control unit 91 will be described.

  The inserted number command is a command that can specify the number of inserted medals, that is, the number of medals used for setting the number of bets, and is a state from the end of the game (after changing the setting) to the start of the game. Or, when a prescribed number of bets is not set, a medal is inserted, or when the bet number is set by operating the MAXBET switch 6. The inserted number command is transmitted when the betting number setting operation is performed, so that it is possible to specify that the betting number setting operation has been performed by receiving the inserted number command.

  The credit command is a command that can specify the number of medals stored as credits, and is a state from the end of the game (after setting change) to the start of the game, and in a state where a predetermined number of bets is set, Sent when a medal is inserted and credits are added.

  The game state command is a command that can specify the game state of the game, and is transmitted when the start switch 7 is operated to start the game.

  The internal winning command is a command capable of specifying the internal lottery result, and is transmitted when the start switch 7 is operated and the game starts, and is transmitted after the gaming state command. The internal winning command includes a first internal winning command and a second internal winning command, and a state in which navigation notification is performed when a notification target role that is a target of navigation notification in the internal lottery is won (AT 1), the first internal winning command that can specify the type of the winning notification target role and the stop order advantageous to the player is transmitted, and the navigation notification is performed. If the state is not performed (when no navigation notification is performed during non-AT), the type of the winning notification target role can be specified, but the stop order advantageous to the player cannot be specified. A command is sent.

  Since the game state command and the internal winning command are transmitted when the start switch 7 is operated and the game starts, it is possible to specify that the game is started by operating the start switch 7 by receiving these commands. It is.

  The stop operation command is a command that can specify whether the reel to be stopped is the left reel, the middle reel, or the right reel, and the area number of the stop operation position of the corresponding reel. Sent every time the accompanying stop control is performed.

  The sliding frame number command is a command that can specify whether the reel to be stopped is a left reel, a middle reel, or a right reel, and the number of sliding frames to be moved from when the corresponding reel is stopped until it stops. Each time stop control associated with the stop operation of each reel is performed, the corresponding stop operation command is transmitted after being transmitted.

  The stop command is a command that can specify whether the reel to be stopped is a left reel, a middle reel, or a right reel, and the area number of the stop position of the corresponding reel. Stop control associated with the stop operation of each reel Is transmitted after the corresponding sliding frame number command is transmitted.

  With the stop operation command, the sliding frame number command, and the stop command, it is possible to specify whether the reel to be stopped is the left reel, the middle reel, or the right reel, and accompanying the stop operation of each reel Since it is transmitted every time stop control is performed, by receiving these commands, it is possible to specify that one of the reels has been stopped and the reel to be stopped.

  The game end command is a command that can specify that the game has ended, and is transmitted when the player presses the stop switch to stop the third stop reel and releases the stop switch.

  The winning number command is a command that can specify a combination of symbols arranged on the winning line LN, whether or not a winning is received, a type of winning, and a payout number of medals at the time of winning. The player stops the third stop reel. This is when the stop switch is pressed and released, and is transmitted after the game end command is transmitted.

  Both the game end command and the winning number command are transmitted when the player depresses the stop switch to release the third stop reel and releases the stop switch. It is possible to specify that all operations necessary to advance one game have been completed.

  The payout start command is a command for notifying the start of payout of medals and is transmitted when the payout of medals by winning is started. 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 is completed.

  The settlement start command is a command indicating the start of the settlement process of medals used for credits or bets, and is transmitted when the settlement process is started. The settlement end command is a command indicating the end of the settlement process, Sent at the end of the checkout process.

  The stand-by command is a command indicating a transition to the stand-by state. When one game is over and the estimated end time (60 seconds in this embodiment) has elapsed and the stand-by state has been reached, Sent after an end command is sent.

  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.

  The error start command is a command that indicates the start of error processing and the type of error, and is transmitted when error processing is started.The error release command is a command that indicates the end of error processing. Sent when the state is released.

  The return command is a command indicating that the main control unit 41 has returned to the control state before the power interruption, and is transmitted when the main control unit 41 returns to the control state before the power interruption.

  The setting command is a command indicating the start or end of the setting change state and the setting value after the setting change. At the time of transition to the setting change state, a setting command indicating the start of the setting change state is transmitted, and when the setting change state ends. A setting command indicating the end of the setting change state and the setting value after the setting change is transmitted. Further, since the control state of the main control unit 41 is initialized with the transition to the setting change state, it can be specified that the control state of the main control unit 41 has been initialized by the setting command indicating the start of setting. .

  The setting confirmation start command is a command that indicates the start of the setting confirmation state, and is transmitted when entering the setting confirmation state. The setting confirmation end command is a command that indicates the end of the setting confirmation state, and the setting confirmation state ends. Sometimes sent.

  The door command is a command indicating the detection state of the door opening detection switch 25, that is, on (open state) / off (closed state), when the power is turned on, at the end of one game (after the game is over, the bet number of the next game) Sent before the setting of ”can be started), and when the detection state of the door opening detection switch 25 changes (from on to off, from off to on).

  The operation detection command is a command indicating the detection state (on / off) of the operation switches (MAXBET switch 6, start switch 7, stop switches 8L, 8C, 8R), and is transmitted at regular intervals.

  Of these commands, commands other than the door command and the operation detection command are generated in the main process, temporarily stored in the command queue provided in the RAM 41c, and transmitted in the subsequent command transmission process of the timer interrupt process (main). The

  On the other hand, the door command is generated in the door monitoring process of the timer interrupt process (main), temporarily stored in the command queue provided in the RAM 41c, and transmitted in the command transmission process of the timer interrupt process (main) thereafter. The

  The operation detection command is generated based on the detection state of the switch every time the command transmission process of the timer interrupt process (main) is executed 10 times, and is temporarily stored in the command queue provided in the RAM 41c. Then, it is transmitted in the command transmission process of the subsequent timer interrupt process (main).

  Next, the control of the effect performed by the sub-control unit 91 based on the command transmitted from the main control unit 41 to the effect control board 90 will be described. When the sub control unit 91 receives a command from the main control unit 41, the sub control unit 91 executes a command reception interrupt process. In the command reception interrupt process, the command acquired from the command transmission line is stored in the reception buffer provided in the RAM 91c.

  In the timer interrupt process (sub), the sub-control unit 91 determines whether or not an unprocessed command is stored in the reception buffer. If an unprocessed command is stored, the sub-control unit 91 is the earliest. The control pattern table stored in the ROM 91b is referred to based on the command received in the stage, and the liquid crystal display 51, effect effect LED 52, speakers 53, 54, reel LED 55, etc. are controlled based on the control contents registered in the control pattern table. Performs output control of various rendering devices. 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 55, etc. Control patterns of these effect devices are registered, and when the sub-control unit 91 receives a command, the sub-control unit 91 stores the control patterns registered corresponding to the effect patterns set in the RAM 91c in the game of the control pattern table. Among these, the control pattern corresponding to the type of the received command is referred to, and the output control of the rendering device is performed based on the control pattern. Thereby, the production according to the production pattern and the progress of the game is executed.

  If the sub-control unit 91 receives a new command during execution of an effect triggered by the reception of a certain command, the sub-control unit 91 stops the effect based on the control pattern being executed, and changes to the newly received command. An effect based on the corresponding control pattern is executed. In other words, even if the production is not finished to the end, when a new command is received, the production that was being executed is canceled and a new command is received unless the received new command is not a command that triggers a new production. An effect based on the 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, and when the sub control unit 91 receives the internal winning command, the sub control unit 91 stores the effect pattern in the effect table according to the result of the internal lottery indicated by the internal winning command. With reference to the registered selection rate, one of the effect patterns is selected from a plurality of types of effect patterns according to the selection rate, and the selected effect pattern is set in the RAM 91c as the effect pattern of the game. Even if the same command is received, a different control pattern is selected depending on the effect pattern selected when the internal winning command is received. As a result, different effects may be performed depending on the effect pattern.

  In the slot machine 1 according to the present embodiment, the main control unit 41 can provide a notification period in which navigation notification can be executed to notify the stop order that is advantageous to the player according to the internal lottery result by the lighting mode of the game auxiliary display 12. Can be controlled at an assist time (hereinafter referred to as AT).

  When the main control unit 41 is controlled by the AT, the main control unit 41 performs navigation notification by winning the navigation target combination corresponding to the gaming state, and transmits a push order command to the sub control unit 91. Thus, a navigation effect using the liquid crystal display 51 or the like is executed. Further, in the present embodiment, the main control unit 41 can execute navigation notification and execute a navigation effect by satisfying certain conditions even in a normal state where the control is not performed by the AT.

  FIG. 6 is an address map of the memory area used by the main control unit 41. As shown in FIG. 6, the memory area used by the main controller 41 includes a memory area (0000H to 7FFFH) allocated to the ROM 41b and a memory area (F000H to FFFFH) allocated to the RAM 41c.

  The memory area of the ROM 41b includes a program / data area (0000H to 26FFH) in which programs and fixed data are stored, a ROM comment area (2700H to 277FH) in which arbitrary data such as a title and version of the program can be set, and a later description. Parameters for setting the hardware table of the vector table area (2780H to 27A7H) in which the upper address of the subroutine of the CALLV instruction to be executed and the start address of the timer interrupt process (main) are set, and the internal function of the main control unit 41 HW parameter area (27A8H to 27FFH) in which is set, and an unused area (2800H to 7FFFH) where access is prohibited.

  The parameters set in the HW parameter area in the ROM 41b include the final address (HPRGEND) of the ROM area used in the program / data area, the start address (HRAMSTAT) and the final address (HRAMEND) of the RAM area for which access is prohibited.

  The memory area of the RAM 41c includes a usable area (F000H to F400H) usable as a work and an internal function register area (F4B0H to F4B0H to store a group of registers for controlling each function mounted on the main control unit 41. F6FFH) and unused areas (F401H to F4AFH, F700H to FFFFH) where access is prohibited.

  FIG. 7 is an address map of the program / data area in the ROM 41b of the main control unit 41 and the usable area in the RAM 41c.

  As shown in FIG. 7A, the program / data area in the ROM 41b includes a game program area in which a game program related to the progress of the game is stored, a game data area in which game data used by the game program is stored, It includes a use area 1, a non-game program area in which a non-game program not related to the progress of the game is stored, a non-game data area in which non-game data used by the non-game program is stored, and an unused area 2. .

  The progress of the game is to advance a series of processes constituting the game. In the case of a slot machine, the stage where the game can be started by setting the number of bets is started and the reel is rotated. A step of stopping the reel, a step of deriving a display result, and a step of assigning a value such as a medal according to the display result.

  A game program area related to the progress of the game and a non-game program not related to the progress of the game are allocated separately, and are allocated backward in the storage area of the ROM 41b among the game program area and the non-program area. Since the unused area 1 of at least 16 bytes or more is allocated to the area before the non-program area, a storage area for the game program area related to the progress of the game and the non-game program not related to the progress of the game It can be easily specified according to the difference.

  The game program area and the game data area, the non-game program area and the non-game data area are allocated to continuous areas, respectively, while the game program area and the game data area related to the progress of the game are not related to the progress of the game. Since the game program and the non-game data area are allocated to areas that are not continuous across the unused area 1 of at least 16 bytes or more, the game program area and game data area related to the progress of the game, and the progress of the game Non-game programs and non-game data areas that are not involved can be easily specified according to the difference in storage areas.

  In the above description, before and after the storage area is a magnitude relationship between the address values assigned to the storage area. The smaller address is the front and the larger address is the rear. For this reason, the storage area allocated behind the one storage area corresponds to the storage area having an address value larger than that of the one storage area, and the storage area allocated ahead of the one storage area. This corresponds to a storage area having an address value smaller than that of one storage area.

  Also, a configuration may be adopted in which a game program is allocated behind the non-game program area, and an unused area is allocated before the game program allocated behind the non-game program area. A game program area related to the progress of the game and a non-game program not related to the progress of the game can be easily specified according to the difference in the storage area.

  Further, the game program area and the non-game program area may be assigned to areas adjacent to each other with the unused area 1 in between, and even in such a structure, the game program area related to the progress of the game Therefore, it is possible to easily identify a non-game program that is not related to the progress of the game according to the difference in storage area.

  In addition, in the unused areas 1 and 2 of the program / data area of the ROM 41b, since 0 values are stored in all areas, a game program area and game data area, a non-game program area and non-game data, The unused areas 1 and 2 can be easily distinguished from each other, and even when invalid data is stored in the unused areas 1 and 2, they can be easily found.

  It should be noted that 1 may be stored in all of the unused areas 1 and 2 of the program / data area of the ROM 41b. Even in such a configuration, the game program area, the game data area, and the non-game The program area and non-game data can be easily distinguished from the unused areas 1 and 2 and can be easily detected even when invalid data is stored in the unused areas 1 and 2. .

  Further, as long as the game program area and the non-game program area are assigned to separate areas, the game program area and the non-game program area may be assigned to adjacent areas. Even with such a configuration, it is possible to easily identify a game program area related to the progress of the game and a non-game program not related to the progress of the game according to the difference in the storage areas.

  The game program area and the non-game program area both start from an address (0H) having the same lower 4 digits when the address is expressed in binary, and the program / data area of the ROM 41b. Among them, the game program area related to the progress of the game and the non-game program area not related to the progress of the game can be easily distinguished from other areas.

  In addition, both the game program area and the non-game program area not only start from an address having the same low-order 4 digit value when the address is expressed in binary, but also the low-order 1 digit value when expressed in hexadecimal. Starts from the same 0 address (0H), so that not only when the address is expressed in binary, but also when it is expressed in hexadecimal, the game program area and the non-game program area are easily distinguished from other areas. can do.

  It should be noted that both the game program area and the non-game program area start from an address having the same value in the lower N (N is a natural number of 1 or more) regardless of whether the address is expressed in binary or hexadecimal. With this configuration, the game program area and the non-game program area can be easily distinguished from other areas. For example, the value of the lower N (N is a natural number of 1 or more) digits is the same 1 The same effect can be obtained with a configuration starting from the address.

  As shown in FIG. 7B, the usable area of the RAM 41c includes a game RAM area used as a work by the game program, a non-game RAM area used as a work by the non-game program, and an unused area 4. The game RAM area includes a special work, an important work, a general work, an unused area 3, and a game stack area in which the game program saves data, and the non-game RAM area includes a game An area where the program can be referred to, an area where the game program cannot be referred to, and a non-game stack area where the non-game program saves data are included. In the present embodiment, the game stack area and the non-game stack area are individually provided in different areas. However, the game stack area and the non-game program may be provided with a single stack area.

  The unused area 3 is an area in which neither a game program nor a non-game program is used, and is an area that is redundant with respect to a game RAM area having a predetermined capacity.

  The unused area 4 is an area of 16 bytes or more in which neither a game program nor a non-game program is used. Since the game RAM area and the non-game RAM area are allocated to areas that are not continuous across the unused area 4, the game RAM area used by the game program related to the progress of the game and the non-related not related to the progress of the game The non-game RAM area used by the game program can be easily specified according to the difference in the storage areas.

  Hereinafter, the game program area, the game data area, and the game RAM area may be collectively referred to as a game area, and the non-game program area, the non-game data area, and the non-game RAM area may be collectively referred to as a non-game area. . Further, the unused area 1 and the unused area 2, the unused area 3 and the unused area 4 may be collectively referred to as an unused area.

  Based on the parameters set in the HW parameter area, the main control unit 41 permits access in the usable area of the RAM 41c when an access is prohibited in the program / data area of the ROM 41b. When there is an access to an area that is not set to, when there is an access to an area other than the program / data area in the ROM 41b, and when there is an access to an area other than the usable area in the RAM 41c, In other words, when an access is made to a memory area that is not accessed in normal operation, an illegal access reset is generated to disable the progress of the game. Therefore, an unused area of the ROM 41b or an area unrelated to the operation If an illegal program is stored in an unused area of the RAM 41c, etc. Even, it is possible to prevent illegal program from being executed.

  In particular, in the present embodiment, a game program area and a non-game program area are allocated to the program / data area of the ROM 41b that is permitted to be accessed by the program, and before the non-game program area behind the game program area. An unused area 1 is assigned to the area, and a group including an area from the start address of the game program area to the final address of the non-game program in the program / data area based on the parameters set in the HW parameter area. While the access to the area (the area from the game program area to the non-game data area) is collectively set to be permitted, the other areas, that is, the program / data area of the game program, game data, non-game program, Non-game data is not stored Because it is forbidden access to the area later than trick data, it is possible to prevent conducted unintended control by malware or illegal data.

  In addition, a game area is allocated behind the non-game program area in the program / data area permitted to be accessed by the program in the ROM 41b, and an unused area in the area before the game program area behind the non-game program area Are allocated to a group of areas including the area from the start address of the non-game program area to the final address of the game program based on the parameters set in the HW parameter area. Thus, while the permission is set, even if access to other areas is prohibited, it is possible to prevent unintended control by an unauthorized program or unauthorized data.

  A game program area and a non-game program area are allocated to the program / data area, an unused area 1 is allocated to an area before the non-game program area behind the game program area, and a program / data Out of the areas, a group of areas including the game program area (area from the game program area to the game data area), a group of areas including the non-game program (area from the non-game program area to the non-game data area) A configuration may be adopted in which access is set to permit and access to other areas is prohibited. Even in such a configuration, a game program or a non-game program is not stored in the program / data area. Access is prohibited, so the intent of unauthorized programs and unauthorized data Can be prevented without control will take place. In addition, a game area is allocated behind the non-game program area in the program / data area permitted to be accessed by the program in the ROM 41b, and an unused area in the area before the game program area behind the non-game program area Of the program / data area including the game program area (the area from the game program area to the game data area), and the area including the non-game program (from the non-game program area to the non-game area). (Access to the data area) may be set to permit, and access to other areas may be prohibited. Even in such a configuration, a game program or non-game in the program / data area Access to an area where no program is stored Because There is inhibited, it is possible to prevent conducted unintended control by malware or illegal data.

  In the above description, the area where access is permitted is set in the program / data area. However, by setting the area where access is prohibited in the program / data area, the area where access is indirectly permitted is set. It is good also as a structure to be performed.

  Based on the parameters set in the HW parameter area, the main control unit 41 executes the user program when the user program is executed in an area other than the designated area where the program travel is permitted, that is, in a normal operation. When the user program is executed in an unoccupied area, the IAT circuit 506a outputs an IAT generation signal to disable the progress of the game. Even if an unauthorized program is stored in the use area or the like, it is possible to prevent the unauthorized program from being executed.

  In particular, in the present embodiment, a game program area and a non-game program area are allocated to the program / data area of the ROM 41b that is permitted to be accessed by the program, and before the non-game program area behind the game program area. The unused area 1 is assigned to the area, and the IAT circuit 506a permits the program running for each of the game program area and the non-game program area in the program / data area based on the parameters set in the HW parameter area. While it is set as a designated area, program running in other areas, that is, areas that do not store gaming programs or non-gaming programs in the program / data area is prohibited. Control line It can be prevented been.

  In addition, a game area is allocated behind the non-game program area in the program / data area permitted to be accessed by the program in the ROM 41b, and an unused area in the area before the game program area behind the non-game program area And the IAT circuit 506a sets each of the game program area and the non-game program area of the program / data area as a designated area that permits program running based on the parameters set in the HW parameter area. Thus, even if the program running in other areas is prohibited, it is possible to prevent unintended control due to unauthorized programs and unauthorized data.

  A game program area and a non-game program area are allocated to the program / data area, an unused area 1 is allocated to an area before the non-game program area behind the game program area, and an HW parameter area. Based on the parameters set in the above, a group of areas including the area from the start address of the game program area to the final address of the non-game program in the program / data area (area from the game program area to the non-game data area) For example, the IAT circuit 506a may be set as a designated area for permitting program running at once and the program running in other areas may be prohibited. Even in such a configuration, the program / data area Of which game programs and non-game programs are stored Since the program running in the absence area is prohibited, it is possible to prevent conducted unintended control by malware or illegal data. In addition, a game area is allocated behind the non-game program area in the program / data area permitted to be accessed by the program in the ROM 41b, and an unused area in the area before the game program area behind the non-game program area Is assigned, and based on the parameters set in the HW parameter area, a group of areas (from the game program area) including the area from the start address of the non-game program area to the final address of the game program in the program / data area. Even if the IAT circuit 506a is collectively set as a designated area for permitting program running and the program running in other areas is prohibited, the area up to the non-game data area) Unintended control It can be prevented been.

  In the above description, the program / data area is configured to set the area that permits the program travel. However, the program / data area allows the program travel to be indirectly permitted by setting the area that prohibits the program travel. A configuration may be adopted in which an area is set.

  The program executed by the main control unit 41 includes a main routine that manages the progress of the entire program, and a subroutine that is called during execution of another program.

  Also, a CALL instruction is included as an instruction for causing the main control unit 41 to execute a program stored in the program / data area.

  The CALL instruction is an instruction for calling and executing a subroutine stored at an address designated in the main routine or the subroutine. When calling the subroutine by the CALL instruction, the main control unit 41 stores the call source address in the stack area, and calls and executes the subroutine stored at the designated address. After the subroutine is finished, the caller address stored in the stack area, that is, the caller main routine or subroutine program that executed the CALL instruction is returned.

  The CALL instruction includes a normal CALL instruction and a CALLV instruction which is a special CALL instruction. The normal CALL instruction is an instruction that specifies a high-order address and a low-order address to specify both the high-order address and the low-order address and calls a subroutine while the CALLV instruction specifies only the low-order address. As a result, the subroutine is called by specifying the address by the upper address preset in the vector table area of the ROM 41b and the designated lower address, and the subroutine is called with a smaller amount of data than the normal CALL instruction. It becomes possible.

  The RST instruction is an instruction to call and execute a subroutine stored at a specific address corresponding to a specified value by specifying a value corresponding to a plurality of predetermined specific addresses. Subroutines can be called with a smaller amount of data than instructions and CALLV instructions. When calling the subroutine by the RST instruction, the main control unit 41 stores the caller's address in the stack area, and calls and executes the subroutine stored at the specific address corresponding to the designated value. After the subroutine is finished, the caller address stored in the stack area, that is, the caller main routine or subroutine that executed the RST instruction is returned to.

  The jump instruction is an instruction to move to a program stored at an address specified in the main routine or subroutine. The main control unit 41 moves to the program stored at the address specified by the jump instruction and executes the destination program. In this case, unlike the CALL instruction or the RST instruction, even if the program after the movement ends, the program does not return to the movement source program.

  The main control unit 41 includes an LD command as a command for reading data stored in the program / data area. The LD instruction is an instruction for reading data stored at a specified address in a main routine or subroutine into a specified register. The main control unit 41 reads the data stored at the address specified by the LD instruction, and stores the read data in the register specified by the LD instruction.

  Among the game programs stored in the ROM 41b, subroutines that are particularly frequently used are stored in an area of the game program area of the ROM 41b where the start address is a specific value (for example, 00H). On the other hand, a specific value is set in the vector table area of the ROM 41b as an upper address of a subroutine called by the CALLV instruction. The main control unit 41 specifies only the lower address using the CALLV instruction when calling a subroutine in which the upper address of the head address has a specific value, thereby specifying the specific value set in the vector table area as the upper address. The lower address specified as the lower address is specified, and the subroutine stored in the address including the upper and lower addresses is called and executed. For this reason, an upper address that constitutes a part of an address used when calling a subroutine that is used frequently in the game program is set in the vector table in advance as a specific value, and is based on the specific value set in the vector table. Since the address is specified, it is possible to call a subroutine with a smaller amount of data compared to a normal CALL instruction that calls a program by specifying both an upper address and a lower address, and when calling these subroutines It is possible to reduce the waste of a program for specifying an address.

  Of the non-game programs stored in the ROM 41b, subroutines that are used frequently are stored in the non-game program area of the ROM 41b in the area where the start address is a specific value, and the CALLV instruction When a specific value is set as an upper address of a subroutine to be called at the time, and the main control unit 41 calls a subroutine in which the upper address of the top address is a specific value, only the lower address is specified by using the CALLV instruction. Even if it is configured to call and execute, subroutines can be called with a smaller amount of data compared to a normal CALL instruction that calls a program by specifying both upper and lower addresses. When calling It is possible to reduce the waste of program for specifying the address.

  In addition, the upper address used when calling with the CALLV instruction may be set in a specific register of the main control unit 41 instead of the vector table area.

  In addition to the CALLV instruction, a part of the address is specified by using a value stored in the vector table area, a value set in a specific register, etc. If a special CALL instruction that enables the storage address to be specified is used, it is possible to reduce the waste of a program for designating an address when calling a subroutine. In addition, identification values having a data amount smaller than the addresses are assigned to the plurality of areas constituting the vector table area, the storage addresses of the subroutines are set in the plurality of areas, and the identification values are designated, thereby identifying the areas. Even in a configuration that uses a special CALL instruction that makes it possible to specify a storage address of a subroutine stored in an area corresponding to a value, it is possible to reduce the waste of a program for designating an address when the subroutine is called. .

  In addition, among the game data stored in the ROM 41b, game data that is frequently used is stored in the game data area of the ROM 41b in an area where the head address is a specific value, and a special LD is stored in the vector table area of the ROM 41b. By setting a specific value as the upper address of the data to be read by the instruction, and when the main control unit 41 calls game data in which the upper address of the top address becomes the specific value, only the lower address is specified by using a special LD instruction. Even when it is configured to read out these game data, it becomes possible to call game data with a smaller amount of data compared to a normal LD command that reads out data by specifying both the upper address and the lower address. When wasting game data, the program for specifying the address is wasted It can be reduced.

  In addition, among the non-game data stored in the ROM 41b, non-game data that is frequently used is stored in the non-game data area of the ROM 41b in the area where the head address is a specific value, and in the vector table area of the ROM 41b, When a specific value is set as an upper address of data read by a special LD instruction and the main control unit 41 calls non-game data whose upper address of the head address is a specific value, only the lower address is used by using a special LD instruction. Even if it is configured to read these non-game data by designating, the non-game data is called with a smaller amount of data compared to a normal LD instruction that designates both the upper address and the lower address and reads data. It is possible to specify the address when reading these non-game data. It is possible to reduce the waste of lamb.

  Even in these cases, the upper address used when calling with a special LD instruction may be set in a specific register of the main control unit 41 instead of the vector table area.

  Also, a part of the address is specified using the value stored in the vector table area, the value set in a specific register, etc., and the data storage address can be specified by specifying the remaining part of the address If the configuration uses a special LD instruction, the waste of a program for designating an address when reading data can be reduced. In addition, identification values with a data amount smaller than the addresses are assigned to the plurality of areas constituting the vector table area, the data storage addresses are set in the plurality of areas, and the identification values are designated to identify the areas. Even in a configuration using a special LD instruction that can specify the storage address of data stored in an area corresponding to a value, it is possible to reduce the waste of a program for specifying an address when reading data .

  The main control unit 41 is activated when a system reset by inputting a system reset signal, a WDT reset by the WDT 506b, or the aforementioned illegal access reset occurs. At this time, the value set in the vector table area, that is, The upper address of the subroutine of the CALLV instruction and the start address of the timer interrupt processing (main) are values indicating the area where the program or the like is actually stored in the program area, or FFFFH (in the unused vector table area) If the value set in the vector table area is neither a value outside the area where the program is set nor FFFFH, it will not start. That unintended processing is executed due to an interrupt. It can be prevented before.

  The game program is a program related to the progress of the game, and is a program for executing a process that hinders the progress of the game unless the process based on the program is executed. On the other hand, a non-game program is a program that is not related to the progress of the game, and even when the game program is called to return to the game program without executing processing based on the program, the game can be advanced. It is a program for executing processing.

  As shown in FIG. 8, the game program includes a game dedicated program included only in the game program, and a common determination program and a common general-purpose program included in both the game program and the non-game program.

  The game dedicated program includes, for example, a game start waiting process, an internal lottery process, a reel control process, a game end setting process, an external output 1 process, an initial setting process, a power interruption process, and an error process. In the game start waiting process, after the control of one game is completed, the bet number is set by inserting medals, etc., and after the prescribed number of bets is set, the start switch 7 is operated to start the game. The internal lottery process is a process of performing an internal lottery and setting a winning flag, etc., and the reel control process starts the rotation of the reels, and the stop switches 8L, 8C, and 8R are operated. In the game end setting process, it is determined whether or not a winning has occurred according to the stop position of the stopped reel, and medals are paid out, re-game is set, and the game state is set. The external output 1 process is a process for performing output control of the medal IN signal, the medal OUT signal, the RB signal, the BB signal, and the RT signal among the external output signals. First The setting process is a process for making the game possible when the power is turned on (confirm backup error, register initialization, etc.), and the power interruption process can return to the state before the power interruption after the power interruption occurs. The error processing includes various abnormalities (medal insertion abnormality, foreign object detection in the medal selector 29, reel rotation abnormality, medal payout abnormality, foreign object detection near the payout outlet, RAM abnormality, setting, etc. This is a process for disabling the game when a value abnormality, empty hopper tank 34a, full tank overflow tank 35, etc. are detected. In addition, although not particularly illustrated, the game program includes processing related to the above-described AT (a lottery related to AT, control related to navigation notification, and the like).

  The common determination program in the game program includes, for example, an input determination process and a payout determination process. The insertion determination process is a process for determining whether or not the medal is normally passed by the inserted medal sensors 31a to 31c, and is a process executed in a state where a medal can be inserted for setting a bet amount or the like. is there. The payout determination process is a process for determining whether or not the medal is normally passed by the payout sensor 34c, and is a process executed in a state where the payout of the medal is permitted at the time of winning a small role or at the time of credit settlement. It is.

  The common general-purpose program in the game program is a process that is called and executed from a plurality of types of processes constituting the game program. For example, a counter update process, a port input process, a data conversion process, an LED display process, a data setting process, Includes command setting processing. The counter update process is a process for updating the designated counter value, the port input process is a process for acquiring the input state of the designated port, and the data conversion process is input using game data. Is a process for converting and outputting the data, the LED display process is a process for setting the specified value to be displayed on the LED, and the data setting process is a process for setting the specified data, The command setting process is a process for setting a specified command in the command queue.

  In particular, the game program, when an abnormality is detected as described above, the release condition corresponding to the type of abnormality (in the case of random number abnormality, RAM abnormality, backup abnormality, setting value abnormality, resetting of the setting value, In the case of an abnormality other than the above, error processing is included that disables the progress of the game until a reset operation is established.

  As shown in FIG. 8, the non-game program includes a non-game dedicated program included only in the non-game program, and a common determination program and a common general-purpose program that are the same as the game program.

  Non-game dedicated programs include, for example, test signal output processing, foreign object detection processing, door monitoring processing, external output 2 processing, inserted medal error determination processing, payout medal error determination processing, power failure determination processing, normal time command transmission processing, power interruption Includes time command transmission processing. The test signal output process is a process for outputting a test signal generated in relation to the game result, and the foreign object detection process is a process for detecting a foreign object in the medal path by the insertion port sensor 26. The door monitoring process is a process for detecting the opening of the front door 1b, and the external output 2 process is a security signal (door open signal, setting change signal, input error signal, payout error signal) among external output signals. The inserted medal error determination process is a process for performing output control. The inserted medal error determination process is performed based on the detection status of the inserted medal sensors 31a to 31c. The medal clogging detection in the medal selector 29 is detected. The payout medal error determination process is a process for detecting the reverse flow of the payout medal based on the detection status of the payout sensor 34c, and the medal near the payout exit. It is a process for detecting clogging and detecting foreign matter near the payout opening, and the power failure determination process is a process for determining whether or not a voltage drop signal from the power interruption detection circuit 48 is detected. The command transmission process is a process for transmitting one command set first in the command queue to the sub-control unit 91 among the commands set in the command queue by the command setting process of the game dedicated program and the non-game dedicated program. Yes, the power interruption command transmission process is a process for transmitting all the commands set in the command queue to the sub-control unit 91.

  The common general-purpose program in the non-game program is a process that is called and executed from a plurality of types of processes constituting the non-game program.For example, the counter update process, the port input process, Includes data conversion processing, LED display processing, data setting processing, and command setting processing.

  The non-game program includes processing for determining whether or not a predetermined detection status is based on the detection status of detection means (the slot sensor 26, the full sensor 35a, and the door opening detection switch 25) that are not involved in the progress of the game.

  In addition, the non-game program functions as a detection means related to the progress of a game in a specific control state among a plurality of control states (game start waiting process, internal lottery process, reel control process, game end time setting process). In other control states, detection means (for example, inserted medal sensors 31a to 31c and payout sensor 34c) functioning as detection means not related to the progress of the game are in a detection state in the control state not related to the progress of the game. Processing for determining whether or not a predetermined detection status is present (for example, inserted medal detection processing or payout medal detection processing for detecting anomalies due to detection of insertion of medals during reel rotation or medal payout) )including. Such a determination process corresponds to the common determination program because it is the same process as the process for determining whether or not the game program is in a predetermined detection status based on the detection status in the control state related to the progress of the game. .

  Of the processes included in the game program, the external output 1 process, the process of counting the number of medals inserted in the game start waiting process, the process of switching the flow path switching solenoid 30, and the number of medals paid out in the game end setting process Processing that does not directly relate to the progress of the game, such as counting, processing for detecting that the hopper tank 34a is empty, processing for updating software random numbers, processing related to AT, transmission processing for internal winning commands, etc. If so, a configuration in which all or part of these processes are included in the non-game program may be employed. On the other hand, as long as the processes included in the non-game program are indirectly related to the progress of the game, all or a part of these processes may be included in the game program.

  In the present embodiment, as shown in FIG. 9, the CPU 41a of the main control unit 41 calls a non-game program in the process based on the game program, executes the process based on the non-game program, and ends the process based on the non-game program. Return to the processing based on the game program.

  As shown in FIG. 9, the CPU 41a, in principle, executes the process based on the game program with reference to the game data in the game data area and uses the game RAM area as a work when executing the process based on the game program. The contents of the game RAM area can be referred to and updated. Further, the CPU 41a, in principle, executes processing based on the non-game program by referring to the game data in the non-game data area, and uses the non-game RAM area as a work. It is possible to refer to and update the contents of the non-game RAM area.

  Further, the CPU 41a does not refer to the non-game data area and does not update the non-game RAM area when executing processing based on the game program, but can refer to the non-game RAM area. In executing the processing based on the non-game program, the game data area is not referred to and the game RAM area is not updated, but the game RAM area can be referred to.

  In addition, the process based on the game program can be referred to only a specific area necessary for the game program in the non-game RAM area (for example, an error flag setting area indicating abnormality detection). In the processing based on the game RAM area, only specific areas required for the non-game program (for example, an internal winning flag setting area, a gaming state setting area, an RT setting area, etc.) can be referred to. In addition, a specific area in the non-game RAM area where the process based on the game program can be referred to, and a specific area in the game RAM area where the process based on the non-game program can be referred to may be assigned to a continuous address area. However, a configuration in which part or all of the address areas are allocated to non-contiguous address areas may be used.

  As described above, in this embodiment, a game program area in which a game program related to the progress of a game is stored, a game data area in which game data referred to by the game program is readable and stored, and work data referred to by the game program Is a game RAM area that is stored so as to be readable and writable, a program that is called by the game program, a non-game program area that stores a non-game program that is not related to the progress of the game, and a non-game that is referenced by the non-game program Since a non-game data area in which data is stored in a readable manner and a non-game RAM area in which work data referred to by the non-game program are stored in a readable and writable manner are separately allocated, a game program, Game data and work program work data; Game program, the workpiece data of the non game data and non-game program, can be easily identified according to a difference in the storage area.

  In addition, by dividing the game program area and the game data area from the non-game program area and the non-game data area, the area occupied by the ROM 41b can be managed in a compact manner according to each function. It becomes easier to specify the corresponding data.

  Further, in this embodiment, when executing the game program, it is possible to refer to the non-game RAM area, and when executing the non-game program, it is possible to refer to the game RAM area. In executing the game program, the data used by the non-game program can be easily used, and in executing the non-game program, the data used by the game program can be used easily. On the other hand, it is impossible to update the non-game RAM area when executing the game program, and it is impossible to update the game RAM area when executing the non-game program. Does not affect the processing of the non-game program, and the non-game program does not affect the processing of the game program.

  Further, in this embodiment, the processing based on the game program can be referred to only a specific area required for the game program in the non-game RAM area (for example, an error flag setting area indicating abnormality detection). The processing based on the non-gaming program can be referred to only specific areas (for example, an internal winning flag setting area, a gaming state setting area, an RT setting area, etc.) necessary for the non-gaming program in the gaming RAM area. Therefore, since the data that can be referred to by the game program in the non-game RAM area and the data that can be referred to by the non-game program are limited to a specific area, the reference destination of the game program or the non-game program can be easily specified. be able to.

  In this embodiment, a game program and a non-game program can be executed, and a game stack area for saving data used by the game program and a non-game stack area for saving data used by the non-game program are separated. The main control unit 41 saves the data used by the game program and the data used by the non-game program in the stack area separately provided, so that the stack area can be managed. It becomes easy. In particular, data used by a game program saved due to the occurrence of a timer interrupt and data used by a non-game program executed during execution of timer interrupt processing (main) are mixed and stored in one stack area. As a result, stack management is not complicated.

  Next, the structure of the medal selector 29 will be described mainly based on FIGS. In the following description, the state where the medal selector 29 is viewed from the back side of the front door 1b will be described as the front side of the medal selector 29.

  The medal selector 29 is formed in a rectangular parallelepiped shape as shown in FIGS. 10 and 11, and a medal flow passage 133 having a substantially L shape in front view is formed inside the main body. As shown in FIGS. 10 (b) and 11 (b), the side wall of the medal flow path 133 is inclined to the front side from the lower side to the upper side so that the upper end of the flowing medal is inclined to the front side rather than the lower end. doing.

  An inflow port 141 communicating with the upstream side of the medal flow passage 133 is formed on the top surface of the main body of the medal selector 29, and medals inserted from the medal insertion port 4 flow into the medal flow passage 133. ing. In addition, an outlet 142 communicating with the downstream side of the medal flow passage 133 is formed on the side surface of the main body of the medal selector 29, and medals discharged from the outlet 142 are guided by the medal chute 149 to be a hopper tank. 34a.

  Further, the aforementioned inlet sensor 26 for detecting the passage of the medal flowing in from the inlet 141 is provided on the upstream side of the medal flow passage 133, and the outlet 142 is provided on the downstream side of the medal flow passage 133. The aforementioned insertion medal sensors 31a to 31c for detecting the passage of the discharged medals are provided.

  In addition, the medal selector 29 discriminates the authenticity (shape, size, thickness, etc.) of the inserted medal, and the genuine medal is detected by the inserted medal sensors 31a to 31c. Then, it flows out from the outlet 142 formed on the side of the main body of the medal selector 29, and the false medal is formed at the lower part of the main body of the medal selector 29 before the passage of the false medal is detected by the inserted medal sensors 31a to 31c. It drops downward from the return unit 137 and is returned to the lower plate from the medal payout opening 9 (see FIG. 1) via the medal return passage 132 (see FIG. 2) provided below the medal selector 29. It has become.

  As shown in FIGS. 10 and 11, the medal flow passage 133 flows down from the position downstream of the position where the passage of the inserted medal is detected by the insertion port sensor 26, below the medal flow passage 133. A flow path switching plate 147 is provided at a position upstream of the position where the passage of medals is detected by the inserted medal sensors 31a to 31c. The flow path switching plate 147 is linked to the excitation of the flow path switching solenoid 30 (see FIG. 4) provided on the front surface side of the main body, and the lower surface of the medal flowing down the medal flow path 133 is not guided (see FIG. 10 (a) (b)) and a guide position (the position shown in FIGS. 11 (a) and 11 (b)) where the lower surface of the medal flowing down the medal flow path 133 is guided. It is attached.

  As shown in FIGS. 10A and 10B, the flow path switching plate 147 is biased so as to be in the non-guide position in a state where the flow path switching solenoid 30 is not excited, thereby allowing the medal flow path 133 to flow. The lower surface of the medal flowing down the medal flow passage 133 is not guided. For this reason, the medal that flows in from the inlet 141 and flows down the medal flow passage 133 is not guided by the flow path switching plate 147, so that the medal falls from the medal flow passage 133 as shown in FIG. Then, it is discharged from the return unit 137 and returned from the medal payout exit 9 through the medal return passage 132.

  Further, when the flow path switching solenoid 30 is excited, the flow path switching plate 147 moves from the non-guide position to the guide position as shown in FIGS. The bottom surface of the flowing medal is guided. Therefore, the medal that flows in from the inlet 141 and flows down the medal flow path 133 is guided from the medal flow path 133 as shown in FIG. Without falling, it flows down toward the outlet 142, is detected by the insertion medal sensors 31a to 31c, and is discharged from the outlet 142.

  In this embodiment, as the insertion port sensor 26 and the insertion medal sensors 31a to 31c, when the medal passes between the light projecting unit and the light receiving unit, the light receiving unit detects the light blocking from the light projecting unit. The photo sensor that detects the passage of the medal is used, but the light projecting part and the light receiving part are arranged at one end of the passage, and the light receiving part detects the light of the light projecting part reflected by the medal, thereby passing the medal. A reflection type sensor for detecting the above may be used. Further, a physical sensor that detects the passage of the medal by detecting the movement of the movable piece that operates in conjunction with the passage of the medal may be used.

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

  First, an initial setting process that is executed by the main control unit 41 at startup will be described. When the main control unit 41 is activated due to the occurrence of a reset, the main control unit 41 performs setting at the time of activation. In the startup setting, a status flag included in the main control unit 41 is initialized. The status flag is data that holds the state of the operation result and execution result of the instruction, and particularly includes an interrupt master permission flag for setting interrupt prohibition / permission. Since the initial value of the interrupt master permission flag is a value indicating prohibition of interrupt, the main control unit 41 is started in a state where interrupt is prohibited. After that, the main control unit 41 sets various functions with reference to the HW parameter, and then performs an initial setting process according to the program stored in the program / data area.

  As shown in FIG. 12, in the initial setting process, interrupts are first prohibited by setting the value of the interrupt master permission flag to a value indicating that interrupts are prohibited (Sa1). As described above, the main control unit 41 is started in an interrupt-inhibited state, but in Sa1, the interrupt is again prohibited. Next, initialization data is set (Sa2), and each output port including the parallel output port 513 is initialized (Sa3). Next, the built-in register is set (Sa4).

  Next, it is determined whether or not the voltage of the power supply is normal (Sa5). If the power supply voltage is not normal, the determination is repeated until normal. If the power supply voltage is normal, the upper address of the interrupt vector is set (Sa6), access to the RAM 41c is permitted (Sa7), and the stack pointer is initialized (Sa8).

  Next, the RAM parity of the game RAM area (game stack area, F000H to F1FFH including the unused area 3) in the usable area of the RAM 41c is calculated (Sa9). Then, it is determined whether or not the calculated RAM parity is 0 (Sa10). As will be described later, if the power-off process (main) is normally performed at the time of the previous power-off, the RAM parity should be 0. If the RAM parity is not 0 in the step of Sd10, the game of the RAM 41c The data stored in the RAM area is not normal. In this case, the process proceeds to step Sa13 to clear the destruction diagnosis data (Sa13). On the other hand, when the RAM parity becomes 0, the data for destructive diagnosis stored in the game RAM area is further acquired (Sa11), and it is determined whether the acquired data for destructive diagnosis is correct (Sa12), Destructive diagnosis data is cleared (Sa13).

  Next, it is determined whether or not the setting key switch 37 is on (Sa14). When the setting key switch 37 is in the on state, a timer interrupt is set (Sa19). Specifically, the register of the timer circuit 509 built in the main control unit 41 is set so that a timer interrupt is periodically executed every predetermined time. In this embodiment, a value corresponding to about 0.56 ms is set in a predetermined register (time constant register), so that a timer interrupt is periodically generated every about 0.56 ms. In the timer circuit 509, the register is set, so that the timer is initialized and starts counting from the initial value. When the timer interrupt setting in step Sa19 is completed, the process proceeds to a setting change process. In the setting change process, each time the reset / setting switch 38 changes from off to on, the set value of the register is updated (in the case of 1 to 5, 1 is added and in the case of 6, it is updated to 1), and the start switch 7 When the setting key switch 37 is turned off after turning from off to on, the setting value data set in the register is stored in the RAM 41c, and the initialization target RAM in the main process described later is stored. The start address is set in the RAM 41c, and the process proceeds to the main process.

  On the other hand, when the setting key switch 37 is in the off state, it is determined whether or not the stored contents of the RAM 41c are destroyed (Sa15). In step Sa15, it is determined whether a RAM abnormality flag, which will be described later, is set, and whether the storage content of the RAM 41c is destroyed based on the determinations in Sa10 and Sa12. If the stored contents of the RAM 41c are not destroyed, a return command is transmitted to the sub-control unit 91 (Sa16). In the case where the stored contents of the RAM 41c are not destroyed, it is determined that the RAM abnormality flag is not set and the RAM parity is 0 in the step Sa10, and further, the destruction diagnosis data is obtained in the step Sa12. This is the case when it is determined to be correct.

  After the step of Sa16, all the registers are restored based on the data stored in the game RAM area of the RAM 41c (Sa17), and the timer interrupt setting similar to the step of Sa19 is performed (Sa18). Then, the process proceeds to Sd24 in a timer interrupt process (main) described later. As a result, the state of the game RAM area and the non-game RAM area of the RAM 41c before the power interruption and the processing executed before the power interruption are restored.

  If the stored content of the RAM 41c is destroyed in step Sa15, a RAM abnormality flag indicating that the stored content of the RAM 41c is not normal is set in the RAM 41c (Sa20), and the process proceeds to error processing. In error processing, the progress of the game is disabled. In addition, the error state that has been shifted after the RAM abnormality flag is set can be canceled by shifting to the setting change process by setting the setting key switch 37 to the on state and turning on the power switch 39. On the other hand, when the power switch 39 is turned on without turning the setting key switch 37 on, the RAM abnormality flag remains set, and it is determined that the RAM is destroyed in step Sa15. It will be in error again.

  As described above, in the present embodiment, the main control unit 41 starts in an interrupt-disabled state when a reset occurs, and then interrupts the program at the start of the initial setting process to be executed first. Prohibition is performed, and it is possible to prevent an unintended interrupt from occurring even when the main control unit 41 is activated in a state where the interrupt is not prohibited for some reason.

  In addition, the main control unit 41 is configured to permit the interrupt after setting the timer interrupt in the timer circuit 509 after the activation, and the interrupt is generated in a state where the timer interrupt does not operate normally. Can be prevented. In the timer circuit 509, the timer is initialized by setting the timer interrupt, and the timer starts counting from the initial value. After starting, the time until the first interrupt occurs Timer interrupts can be generated at regular time intervals without any deviation from the time until the second and subsequent interrupts are generated. In addition, the main control unit 41 is configured to update the setting of the timer circuit 509 to the initial value by a program in the initial setting process, and when the setting of the timer circuit 509 is rewritten for some reason at the time of activation. Even if it exists, it can prevent that the unintended interruption generate | occur | produces.

  Next, main processing executed by the main control unit 41 will be described with reference to FIG. The main process is repeatedly executed for each unit of game. One period of the main process corresponds to one unit of the game.

  As shown in FIG. 13, the main control unit 41 first prohibits an interrupt (Sb1). Next, the final address of the initialization target RAM (the final address of the game stack area (unused)) is set (Sb2), the game area initialization process is executed, and the area of the RAM 41c indicated by the designated address is cleared. (Sb3).

  In the game area initialization process, the designated RAM area is initialized among the game RAM areas by sequentially clearing the designated start address to end address. At this time, if the main process is started after the setting change process, the special work among the usable areas is stored as the start address of the initialization target RAM when the setting change process is ended. Since the final address of the game stack area (unused) is set as the final address of the initialization target RAM in Sb2 of the main process, the address next to the final address of the game RAM area is set. In addition, areas other than the game stack area (in use) (important work, general work, unused area 3, and stack area (unused)) are initialized. At the end of a game that is not in a specific gaming state, the initial address of the RAM to be initialized at the end of the game (the initial address of the unused area 3) is set at the step Sb10 described later, and is initialized at the step Sb2. Since the final address of the target RAM (the final address of the game stack area (unused)) is set, the unused area 3 and the game stack area (unused) among the available areas are initialized. Also, at the end of the specific gaming state and at the end of the game, the initial address of the initialization target RAM at the end of the specific gaming state (a special work in the gaming RAM area is stored at the step Sb11 described later). In the Sb2 step, the final address of the initialization target RAM at the end of the specific gaming state (final address of the gaming stack area (unused)) is set. Therefore, in the game RAM area, the general work, the unused area 3, and the game stack area (unused) are initialized.

  After initialization of the RAM in step Sb3, interrupt is permitted (Sb4), and a game start waiting process is called and executed (Sb5). In the game start waiting process, the process waits in a state where a bet number can be set, and a process for starting a game is executed when a specified number of bets are set according to the game state and the start switch 7 is operated.

  Next, an internal lottery process is executed (Sb6). In the internal lottery process, whether or not to win the above-mentioned winning combination based on the internal lottery random value latched simultaneously with the start of the game by the detection of the start switch 7 in the step Sb5 (that is, the display result is derived). The process of determining whether or not to allow) is performed.

  Next, a reel control process is executed (Sb7). In the reel control process, the process of rotating each reel 2L, 2C, 2R in response to the operation of the start switch 7, the result of the internal lottery in the step of Sd2, and the operation of the stop switch 8L, 8C, 8R by the player are detected. In response to this, processing for stopping the rotation of the corresponding reels 2L, 2C, 2R is executed.

  Next, a game end time setting process is executed (Sb8). In the game end setting process, when it is determined that the rotation of all the reels 2L, 2C, 2R is stopped in the process of Sb7, a winning occurs according to the display result derived for each reel 2L, 2C, 2R. The process which determines whether or not is executed. When it is determined that a winning has occurred, processing such as credit addition and medal payout is performed based on the number of payouts according to the winning. When a winning occurs, a process for setting a gaming state for the next game is executed after the medal payout is completed. Further, when no winning occurs, after the reels are stopped, processing for setting a gaming state for the next game is executed.

  When the game end setting process ends, it is determined whether or not the specific game state is ended (Sb9). If it is not the specific game state end, the initial address of the initialization target RAM at the end of the game is determined. Set (Sb10) and return to the step of Sb1. If it is at the end of the specific gaming state, the initial address of the initialization target RAM at the end of the specific gaming state is set (Sb11), and the process returns to the step Sb1.

  Also, in the main process, a command storing process for generating a command according to the progress of the game and setting the command in the command queue is executed, and the set command is executed in the normal timer execution process (main) thereafter. It is transmitted to the sub-control unit 91 by command transmission processing.

  As described above, in this embodiment, the main control unit 41 starts the initial setting process when the power supply to the slot machine 1 is started, and the RAM in the game RAM area of the RAM 41c held by the backup power source. It is determined whether or not the stored contents of the RAM are normal based on the parity and the destructive diagnosis data stored in the game RAM area, and if it is determined to be normal, the data stored in the game RAM area and the non-game Control is resumed based on the data stored in the RAM area, and whether or not the non-game data stored in the non-game RAM area and that does not interfere with the progress of the game is normal is determined. By omitting, it is possible to reduce the load at the time of resuming the control while ensuring that the game can proceed normally.

  The game RAM area of the RAM 41c includes an unused area 3 that is not used when performing control based on a game program or when performing control based on a non-game program. When the power supply to the slot machine 1 is started, the initial setting process is executed. In the initial setting process, the RAM parity of the game RAM area including the unused area 3 is calculated, and the calculated RAM parity is calculated. Based on this, it is determined whether or not the stored contents of the game RAM area are normal, so that illegal data can be prevented from being stored in the unused area 3.

  Further, the main control unit 41 executes an initial setting process when power supply to the slot machine 1 is started, determines whether or not the storage contents of the RAM 41c are destroyed in the initial setting process, and the RAM 41c. When it is determined that the stored contents are destroyed, the RAM abnormality flag is set and the error processing is controlled, and then the error state is maintained without being automatically restored, while the setting key switch 36 is turned on. In this state, when the power supply to the slot machine 1 is started, the setting control process is controlled, the game area initialization process is executed to initialize the game RAM area, and the non-game area initialization process is executed. When executed, the non-game RAM area is initialized, that is, both the game RAM area and the non-game RAM area are initialized as the error state is released. While game any abnormality has occurred in the M region and the non-gaming RAM area it can be prevented from proceeding.

  Next, the game start waiting process that the main control unit 41 calls and executes in the main process will be described with reference to FIGS.

  As shown in FIG. 14, in the game start waiting process, first, the value of the BET counter in which the value of the betting number is stored in the RAM 41c is cleared (Sc1). Then, a prescribed number corresponding to the gaming state is set in the RAM 41c (Sc2), and whether or not the game is a replay game based on whether or not the replay game flag indicating that the game is a replay game is set in the RAM 41c. Is determined (Sc3).

  If it is determined in step Sc3 that the game is a replay game, the value of the BET counter is incremented by 1 (Sc4), and the BET counter is referenced with reference to the prescribed number of bets set in the RAM 41c. It is determined whether or not the value is a specified number, that is, whether or not the number of bets serving as a game start condition is set (Sc5). If the value of the BET counter is not a specified number in the step of Sc5, the process returns to the step of Sc4. On the other hand, if the value of the BET counter is a specified number, the process proceeds to the step of Sc6, and the credit value as will be described later. In response to this, a process for determining whether or not a medal can be inserted is executed. On the other hand, if it is determined in step Sc3 that the game is not a replay game, the process proceeds to step Sc6, where a throw-in / out determination process is executed.

  After executing the throw-in availability determination process in the step of Sc6, it is determined whether or not an error code is set in the register, that is, whether or not an error has been detected (Sc7). The process proceeds to the waiting-for-start error process (Sc8). On the other hand, if the error code is not set in the step of Sc6, it is determined whether or not the setting key switch 37 is on (Sc9). If the setting key switch 37 is on, the BET counter is checked. It is determined whether it is 0 (Sc10). When the setting key switch 37 is on in the step of Sc9 and the BET counter is 0 in the step of Sc10, a setting confirmation process for displaying a setting value for confirmation is executed as described later (Sc11).

  Then, after the setting confirmation process is completed, or when the setting key switch 37 is not on in the step of Sc9, if the BET counter is not 0 in the step of Sc10, the process proceeds to the step of Sc12, and a medal is inserted as described later. A medal insertion determination process is performed (Sc12).

  After the medal insertion determination process is executed in the step of Sc12, it is determined whether any of the start switch 7, the MAXBET switch 6, and the checkout switch 10 has changed from the off state to the on state (Sc13, Sc22, Sc27) If it is determined that none of the switches have changed from the off state to the on state, the process returns to the step of Sc7.

  In the step of Sc13, when it is determined that the start switch 7 has changed from the off state to the on state, it is determined whether or not the other switch is on (Sc14), and it is determined that the other switch is not on. If so, it is determined whether or not the value of the BET counter is a specified number (Sc15). If it is determined in step Sc14 that the other switches are on, or if it is determined in step Sc15 that the value of the BET counter has not reached the specified number, the process returns to step Sc7. On the other hand, if it is determined in step Sc14 that the other switches are not turned on, and the value of the BET counter has reached the specified number in step Sc15, the value of the random number storage work is set in the lottery work in the RAM 41c. It is set (Sc16), the insertion possible flag is cleared (Sc17), the value of the output port corresponding to the flow path switching solenoid 30 is set to a value indicating off (Sc18), and the medal flow path is the path on the medal payout exit 9 side. And prohibiting the insertion of a new medal, and setting the insertion request LED 17 to the off state (Sc19). Then, a detection time invalidation timer for invalidating detection of the medal clogging error by the inserted medal sensors 31a to 31c over a predetermined period (500 ms in this embodiment) is set (Sc20), and the setting at the start of the game is performed. (Sc21), the game start waiting process is terminated and the process returns to the main process.

  In the step of Sc22, when it is determined that the MAXBET switch has changed from the off state to the on state, it is determined whether or not the value of the BET counter has reached a prescribed number (Sc23), and has not reached the prescribed number. In this case, it is determined whether or not the value of the credit counter is 0 (Sc24). In the step of Sc24, when the value of the credit counter is not 0, the credit counter is decremented by 1 (Sc25), the BET counter is incremented by 1 (Sc26), the process returns to the step of Sc23, and the value of the BET counter reaches the specified number. Or, the processes of Sc23 to Sc26 are repeated until the value of the credit counter becomes zero. If it is determined in step Sc23 that the value of the BET counter has reached the specified number, or if it is determined in step Sc24 that the value of the credit counter is 0, the process returns to step Sc7.

  In the step of Sc27, when it is determined that the settlement switch 10 has changed from the off state to the on state, a settlement process for returning medals used for setting credits or bets is executed as will be described later (Sc28). Then, after the settlement process is completed, the process returns to the step of Sc7.

  In the game start waiting process according to this embodiment, the process proceeds to the setting confirmation process when the setting key switch 37 is turned on and the value of the BET counter is 0 with no error code set. In other words, when the bet amount is set by the MAXBET switch 6, when the re-gamer wins and the bet number is set, the configuration is not shifted to the setting confirmation process. When the setting key switch 37 is turned on in the period from the start until the operation of the start switch 7 is detected and no error code is set, the value of the BET counter is 0. Regardless of whether or not the number of bets has been set according to the operation of the MAXBET switch 6 or the winning of the re-gamer, it is not necessary to determine whether or not there is. It may be configured to shift to processing.

  Next, the medal insertion determination process executed by the main control unit 41 will be described with reference to FIG.

  As shown in FIG. 17, in the medal insertion determination process, it is determined whether or not the insertion possible flag is set (Sd1), and the insertion possible flag is set and the medal can be inserted. Acquires the transition data of the inserted medal sensors 31a to 31c (Sd2), and when the insertable flag is not set and the medal cannot be inserted, the medal insertion determination process is terminated, Return to the game start waiting process.

  After acquiring the transition data of the inserted medal sensors 31a to 31c in the step of Sd2, whether or not a medal is passing in the direction of the outlet 142 in the medal flow path 133 of the medal selector 29 based on the acquired transition data. Is determined (Sd3). If it is determined in step Sd3 that the medal is not passing, the value of the output port corresponding to the flow path switching solenoid 30 is set to a value indicating on (Sd4), and the medal flow path 133 is set to the outlet 142 side. The insertion of a new medal is permitted, the insertion request LED 17 is set to the on state (Sd5), and the process proceeds to step Sd6. On the other hand, if it is determined in step Sd3 that a medal is passing, the flow proceeds to step Sd6 without setting the flow path switching solenoid 30 and the insertion request LED 17 to the on state.

  In step Sd6, it is determined whether or not the transition data acquired in step Sd2 is normal. If it is determined that the transition data is normal, the outputs of the inserted medal sensors 31a to 31c further change. Whether or not (Sd7). If it is determined in step Sd6 that the transition data is not normal, an error code indicating a insertion error is set (Sd13), the medal insertion determination process is terminated, and the output of the insertion medal sensors 31a to 31c is completed in step Sd7. Even if it is determined that there is no change, the medal insertion determination process is terminated and the process returns to the game start waiting process.

  If it is determined in step Sd6 that the transition data of the inserted medal sensors 31a to 31c is normal, and it is determined in step Sd7 that there is a change in the output of the inserted medal sensors 31a to 31c, It is determined whether any of the outputs of the inserted medal sensors 31a to 31c is on (Sd8).

  If it is determined in step Sd8 that one of the outputs of the inserted medal sensors 31a to 31c is in the on state, whether or not a one-sheet insertable flag described later with reference to the RAM 41c is set, that is, The medal detected by the inserted medal sensors 31a to 31c is the final medal that can be inserted into the slot machine 1, and it is determined whether or not the credit value reaches the upper limit by inserting this medal. In the step of Sd9, when the one-sheet insertable flag is set, the value of the output port corresponding to the flow path switching solenoid 30 is set to a value indicating off (Sd10), and the medal flow passage 133 is set to the medal payout exit. 9 is switched to prohibit the insertion of a new medal, the insertion request LED 17 is set to the off state (Sd11), and the detection time is invalidated to invalidate the detection of the medal clogging error by the insertion medal sensors 31a to 31c. After setting the timer (Sd12), the medal insertion determination process is terminated and the process returns to the game start waiting process. On the other hand, if it is determined in step Sd9 that the one-sheet insertable flag is not set, the medal insertion determination process is terminated without performing steps Sd10 to Sd12, and the process returns to the game start waiting process.

  If it is determined in step Sd8 that none of the outputs of the inserted medal sensors 31a to 31c is on, the value of the BET counter is referred to determine whether or not the number of bets has reached a specified number. If the number of bets has not reached the specified number (Sd14), 1 is added to the BET counter (Sd15), and after the insertion possibility determination process described later is executed, the medal insertion determination process is terminated and the game starts. Return to wait processing. On the other hand, if it is determined in step Sd14 that the number of bets has reached the specified number, 1 is added to the credit counter (Sd17), and after the insertion possibility determination process described later is executed, the medal insertion determination process ends. Then, the process returns to the game start waiting process.

  As described above, in the medal insertion determination process, when the insertion possible flag is set and the medal is not passing, the flow path switching solenoid 30 and the insertion request LED 17 are controlled to be in the off state.

  In the medal insertion determination process, the transition data of the insertion medal sensors 31a to 31c is normal, and the output of any of the insertion medal sensors 31a to 31c changes from off to on, and a one-sheet insertion possible flag is set. In other words, when the insertion of the final medal that can be inserted into the slot machine 1 is detected, the flow path switching solenoid 30 and the insertion request LED 17 are controlled to the off state. For this reason, when a single insertable flag is set and the inserted medal sensor 31a detects a medal, before the other inserted medal sensors 31b and 31c detect the medal, the medal downflow passage is set to the outlet. In the state where only one medal can be inserted from the 142 side to the medal return passage 132 side, the medal flow-out path is the outlet as early as possible after the last one medal is inserted. Since the medal return path 132 is switched from the 142 side, it is possible to prevent the medal from being taken into the inside even when the medal further flows down.

  Also, when the flow path switching solenoid 30 is switched from on to off, a detection time invalidation timer is set. Thereafter, even if the detection time of the inserted medal sensors 31a to 31c exceeds the medal clogging determination time over a predetermined period, a medal clogging error occurs. After the medal flow path has been switched from the outlet 142 side to the medal return path 132 side, the inserted medals are forced to flow down the medal flow path 133 toward the outlet 142 side. In this case, even if the passing speed of medals becomes slower than usual, it is not determined that a medal clogging error has occurred.

  Further, when the transition data of the inserted medal sensors 31a to 31c is normal and the output of the inserted medal sensors 31a to 31c changes from on to off, that is, the medals flowing down the medal flow path 133 normally flow down to the outlet 142. In this case, the inserted medals are added to the bet number or credit.

  Next, the insertion permission / inhibition determination process executed by the main control unit 41 will be described with reference to FIG. The insertion permission / inhibition determination process is made into a common module so that it can be called based on each process such as a game start waiting process, a medal insertion determination process, a settlement process, a setting confirmation process, and an error process.

  As shown in FIG. 18, in the insertion permission / inhibition determination process, the credit counter and the BET counter assigned to the game RAM area of the RAM 41c are referred to specify the credit value and the bet number, and the game data area of the ROM 41b is set. The upper limit number of credits (50 in this embodiment) is specified with reference (Se1). Whether the sum of the credit value and the bet amount has reached the maximum number of medals that can be inserted (in this embodiment, the sum of the upper limit number of credits 50 and the maximum number of bets 3). (Se2), and when it is determined that the sum of the credit value and the bet number has reached the maximum number of medals that can be inserted, the insertion possible flag indicating that medals can be inserted is cleared. (Se3), the input permission / inhibition determination process is terminated, and the process returns to the caller process.

  On the other hand, in the step of Se2, if it is determined that the sum of the credit value and the bet number has not reached the maximum medal number that can be inserted, the sum of the credit value and the bet number is It is determined whether or not the number has reached one less than the maximum number of medals that can be inserted (Se4). In the step of Se4, the sum of the credit value and the bet number has reached one less than the maximum number of medals that can be inserted, that is, only one more medal can be inserted into the slot machine 1 Is set, a single insertion possible flag indicating that one more medal can be inserted is set (Se5), an insertion possible flag is set (Se6), and the insertion possibility determination processing is ended. On the other hand, if the sum of the credit value and the bet number has not reached one less than the maximum number of medals that can be inserted in the step of Se5, the insertion possible flag is set (Se6) The availability determination process is terminated.

  In this way, since the process for determining whether or not the game can be inserted is included in the game program as a common module, it can be called based on the settlement process, the setting confirmation process, and the error process. The capacity can be reduced.

  In addition, in the insertion possibility determination process of the present embodiment, when it is determined that the sum of the credit value and the bet number has not reached the maximum number of medals that can be inserted, an insertion possible flag is set. By setting the insertable flag, it is referred to in the medal insertion determination process after the insertability determination process, and in accordance with the determination result in the insertability determination process, that is, the insertable flag is set, The flow path switching solenoid 30 is turned on.

  Further, when it is determined that the sum of the credit value and the bet number has reached one less than the maximum number of medals that can be inserted, a one-throwable flag is set. By setting the one-sheet insertion-possible flag, it is referred to when the passage of medals inserted in the medal insertion determination process is detected after the insertion determination process, the determination result in the insertion determination process, That is, the flow path switching solenoid 30 is turned off in response to the setting of the one-sheet insertion possible flag.

  In this embodiment, the maximum number of medals that can be stored in the credit (50 in this embodiment) is stored in the game data area of the ROM 41b. In the insertion possibility determination process, the game data area of the ROM 41b is stored. The maximum number of credits is specified with reference to the value set in.

  Next, the settlement process executed by the main control unit 41 in the game start waiting process will be described with reference to FIG.

  As shown in FIG. 19, in the settlement process, first, it is determined whether or not the bet amount is set (Sf1). If it is determined in step Se1 that the bet number has been set, it is further determined whether or not the game is a replay game (Sf2). If the game is not a replay game, the bet value is set as the number of returned medals. The number of bets is set to 0 (Sf3).

  If it is determined that the number of bets is not set in step Sf1, or if it is determined that the game is a replay game in step Sf2, it is determined whether or not the credit is 0 (Sf4). If it is 0, the settlement process is terminated and the process returns to the game start waiting process. If the credit is not 0 in the step of Sf4, the credit value is set as the number of returned medals and the credit value is set to 0 (Sf5).

  After the step of Sf3 or Sf5, the insertion possible flag indicating that the medal can be inserted is cleared (Sf6), and a settlement start command indicating that the settlement process is started is set in the command queue (Sf7). Then, by setting the value of the output port corresponding to the flow path switching solenoid 30 to a value indicating off, insertion of a new medal is prohibited using the medal flow path as a path on the medal payout exit 9 side (Sf8), The insertion request LED 17 is turned off (Sf9), and a detection time invalidation timer for invalidating detection of the medal clogging error by the insertion medal sensors 31a to 31c is set for a predetermined period (500 ms in this embodiment) (Sf10). ), A medal return process for causing the hopper unit 34 to return medals for the number of return medals set in the step Sf3 or Sf5 (Sf11). In the medal return process, a process of driving the hopper motor 34b is performed until a payout of medals for the number of returned medals is detected.

  In step Sf11, after returning the medals for the number of returned medals, the insertability determination process described with reference to FIG. 17 is executed (Sf12), and then a settlement end command indicating that the settlement process is terminated is set (Sf13). ), The settlement process is terminated, and the process returns to the game start waiting process.

  As described above, in this embodiment, when the settlement process is executed, the flow path switching solenoid 30 is handled regardless of whether or not the process for setting the flow path switching solenoid 30 to the on state has already been performed. By setting the value of the output port to a value indicating off, the flow path switching plate 147 of the medal selector 29 is positioned at the non-guide position, and the medal flow path 133 is switched to the return unit 137 side.

  Further, in this embodiment, when the adjustment process is started, the insertion-possible flag indicating that the medal can be inserted is cleared, so that the medal cannot be inserted, and then the flow path switching solenoid 30 is turned off. When the insertion possible flag is cleared, the medal insertion determination based on the insertion medal sensors 31a to 31c is not performed.

  In this embodiment, when the settlement process is started, a settlement start command is sent to the sub-control unit 91 by setting a settlement start command indicating that the settlement process has started. . The sub-control unit 91 that has received the settlement start command performs a settlement informing notification that the settlement process is being executed, and displays on the liquid crystal display 51 that the settlement process is being performed. In addition to the display, a sound indicating that the settlement process is being executed is output from the speakers 53 and 54 to notify the player that the settlement process is being executed and that the medal insertion slot 4 cannot be inserted. .

  Further, in this embodiment, after the medal return process to be returned by the hopper unit 34 in the settlement process is completed, a settlement termination command indicating that the settlement process is terminated is set to the sub-control unit 91 to complete the settlement. A command is sent. Note that the sub-control unit 91 that has received the settlement end command terminates the notification indicating that the settlement process is being executed.

  Further, in this embodiment, by setting the detection time invalidation timer when the flow path switching solenoid 30 is set to the off state in the settlement process, the medal clogging error is performed over a predetermined period (500 ms in this embodiment). Detection is now disabled.

  In the present embodiment, when the flow path switching solenoid 30 is set to the off state in the settlement process, the input request LED 17 is turned off.

  Further, in this embodiment, when the settlement process is terminated, the insertion possibility determination process is called and executed, and the sum of the bet number, the credit value, and the bet number reaches the maximum number of medals that can be inserted. If the total number of bets, credits, and bets has not reached the maximum number of medals that can be inserted, the insertable flag is set. Therefore, in the game start waiting process that returns after the settlement process is completed, the flow switching solenoid 30 is turned on-off according to the determination result in the input possibility determination process, that is, whether or not the input possibility flag is set. Will be switched.

  Next, the setting confirmation process executed by the main control unit 41 in the game start waiting process will be described with reference to FIG.

  As shown in FIG. 20, in the setting confirmation process, first, the insertion possible flag indicating that a medal can be inserted is cleared (Sg1), and the value of the output port corresponding to the flow path switching solenoid 30 is set to off. By setting the value, the insertion of a new medal is prohibited using the medal flow path as a path on the medal payout exit 9 side (Sg2), the insertion request LED 17 is turned off (Sg3), and a predetermined period (in this embodiment, The detection time invalidation timer for invalidating the detection of the medal clogging error by the inserted medal sensors 31a to 31c is set for 500 ms) (Sg4).

  Then, the setting value currently set is displayed on the setting value display 24 (Sg5), a setting confirmation start command indicating that the setting confirmation processing is started is set in the command queue (Sg6), and the setting key switch 37 is It is determined whether or not the setting key switch 37 is in the on state (Sg7). If the setting key switch 37 is in the on state, the process waits until the setting key switch 37 is in the off state.

  If it is determined in step Sg7 that the setting key switch 37 is not in the on state, the display of the setting value display 24 is cleared (Sg8), and the input permission / inhibition determination process is called and executed (Sg9). Then, after the insertion permission / inhibition determination process is completed, a setting confirmation end command indicating that the setting confirmation process is ended is set (Sg10), and the process returns to the game start waiting process.

  As described above, in the present embodiment, when the setting check process is executed, the flow path switching solenoid 30 is supported regardless of whether the flow path switching solenoid 30 is already set to the on state. By setting the value of the output port to be set to a value indicating off, the flow path switching plate 147 of the medal selector 29 is positioned at the non-guide position, and the medal flow path 133 is switched to the return unit 137 side. .

  Further, in this embodiment, when the setting check process is started, the insertion switch flag indicating that the medal can be inserted is cleared to make it impossible to insert the medal, and then the flow path switching solenoid 30 is turned off. When the insertion possible flag is cleared, the medal insertion determination based on the insertion medal sensors 31a to 31c is not performed.

  In this embodiment, when the setting check process is started, a setting check start command indicating that the setting check process is started is set, so that the setting check start command is transmitted to the sub-control unit 91. It has become. The sub-control unit 91 that has received the setting check start command executes a setting check notification for notifying that the setting check is being performed and causes the speakers 53 and 54 to output a sound indicating that the setting check is being performed. The player is informed that the setting is being confirmed and that the medal cannot be inserted through the medal slot 4.

  Further, in this embodiment, when the setting key switch 37 is turned off in the setting confirmation process and the setting confirmation process is terminated, a setting confirmation end command indicating that the setting confirmation process is terminated is set. A setting confirmation end command is transmitted to the sub-control unit 91. The sub-control unit 91 that has received the setting confirmation end command terminates the notification indicating that the setting is being confirmed.

  Further, in this embodiment, when the flow path switching solenoid 30 is set to the off state in the setting confirmation process, the medal detection invalidation timer is set, so that it is turned on for a predetermined period (500 ms in this embodiment). Detection by the medal sensors 31a to 31c is invalidated.

  In the present embodiment, when the flow path switching solenoid 30 is set to the off state in the setting confirmation process, the input request LED 17 is turned off.

  Further, in this embodiment, when the setting confirmation process is terminated, the insertion possibility determination process is called and executed, and the sum of the bet number, the credit value, and the bet number becomes the maximum number of medals that can be inserted. If the total number of bets, credits, and bets has not reached the maximum number of medals that can be inserted, the thrown-in flag is set. Therefore, in the game start waiting process that returns after the setting confirmation process is completed, the flow path switching solenoid 30 is turned on according to the determination result in the input possibility determination process, that is, whether or not the input possibility flag is set. The -off state will be switched.

  Next, the waiting start error process executed by the main control unit 41 in the game start waiting process will be described with reference to FIG.

  As shown in FIG. 21, in the waiting-for-start error process, first, the insertion possible flag indicating that a medal can be inserted is cleared (Sh1), and the value of the output port corresponding to the flow path switching solenoid 30 is turned off. Is set to a value indicating that the medal flow path is a path on the medal payout exit 9 side, the insertion of a new medal is prohibited (Sh2), the insertion request LED 17 is turned off (Sh3), and a predetermined period (in this embodiment) is set. Then, a detection time invalidation timer for invalidating detection of medal clogging errors by the inserted medal sensors 31a to 31c is set for 500 ms) (Sh4).

  Then, an error start command indicating that error processing has started is set in the command queue (Sh5), the set error code is displayed on the game auxiliary display 12 (Sh6), and an error cancel condition (reset operation) Is determined (Sh7), and if the error cancel condition is not satisfied, the process waits until the error cancel condition is satisfied.

  If it is determined in the step of Sh7 that the error canceling condition is satisfied, the display of the error code on the game auxiliary display 12 is cleared (Sh8), and the insertion permission / inhibition determination process is called and executed (Sh9). Then, after the insertion permission / inhibition determination process is completed, an error release command indicating that the error process is to be ended is set (Sh10), and the process returns to the game start waiting process.

  As described above, in this embodiment, when the waiting-for-start error process is executed, the flow path switching solenoid 30 is set regardless of whether the flow path switching solenoid 30 is already set to the on state. By setting the value of the output port corresponding to to a value indicating off, the flow path switching plate 147 of the medal selector 29 is positioned at the non-guide position, and the medal flow path 133 is switched to the return unit 137 side. ing.

  Further, in this embodiment, when the error processing for waiting for start is started, the flow path switching solenoid 30 is set after the insertion possible flag indicating that the medal can be inserted is cleared to make it impossible to insert the medal. Is set to the off state, and when the insertion possible flag is cleared, the medal insertion determination based on the insertion medal sensors 31a to 31c is not performed.

  Further, in this embodiment, when the error processing waiting for start is started, an error start command is set to indicate that error processing has started, so that the error start command is transmitted to the sub-control unit 91. It has become. The sub-control unit 91 that has received the error start command performs in-error notification to notify that error processing is being performed, and outputs sound indicating that error processing is being performed from the speakers 53 and 54. The player is informed that an error is occurring and that a medal cannot be inserted through the medal slot 4.

  Further, in this embodiment, when an error release condition is established in the error processing for waiting for start and the error processing for waiting for start is ended, an error release command indicating that the error processing is ended is set, An error cancel command is transmitted to the sub-control unit 91. Note that the sub-control unit 91 that has received the error cancellation command terminates the notification indicating that error processing is in progress.

  Further, in this embodiment, when the flow path switching solenoid 30 is set to the off state in the waiting-for-start error process, the medal detection invalidation timer is set so that the predetermined period (500 ms in this embodiment) is set. The detection by the inserted medal sensors 31a to 31c is invalidated.

  Further, in this embodiment, when the flow path switching solenoid 30 is set to the off state in the start waiting error process, the input request LED 17 is turned off.

  Further, in this embodiment, when ending the waiting-for-start error process, the insertion possibility determination process is called and executed, and the sum of the bet number, the credit value, and the bet number is the maximum medal that can be inserted. If the number has reached the maximum number of medals, the sum of the bet number, the credit value, and the bet number has not been reached. Therefore, in the game start waiting process that returns after the waiting-for-start error process is completed, the flow path switching is performed according to the determination result in the input possibility determination process, that is, whether or not the input possibility flag is set. The on-off state of the solenoid 30 is switched.

  The main control unit 41 of the present embodiment executes a timer interrupt process (main) that interrupts and executes the main process at regular intervals (intervals of about 0.56 ms). The timer interrupt process (main) is a process executed by an interrupt generated according to the count of the timer circuit 509. The address at which the timer interrupt process (main) program is stored is stored in the vector table. It is set as a value corresponding to the timer interrupt. When a timer interrupt occurs, processing from that address is executed. Further, other interrupts are automatically prohibited during the execution period of the timer interrupt process (main).

  In the timer interrupt process (main), the power failure determination process is called and executed, and it is determined whether or not a voltage drop signal is input from the power interruption detection circuit 48, and two successive timer interrupt processes (main) When it is determined that a voltage drop signal is input over the entire period, it is determined that a power failure has occurred and the process proceeds to a power interruption process (main). The power interruption process will be described with reference to FIG.

  As shown in FIG. 22, in the power interruption process (main), the main control unit 41 first saves all the registers that may be used in the stack area (Si1).

  Next, all output ports including the parallel output port 513 that outputs a command are initialized (Si2). As a result, the output state of the output port corresponding to the last command output by the power interruption command transmission process is initialized. Then, the destructive diagnosis data is set in the game RAM area (Si3). Destructive diagnosis data is 5A (H), that is, a value including 1 in any bit. Next, the RAM parity adjustment data is calculated and set in the game RAM area so that the exclusive OR of all areas of the game RAM area (including the unused area 3) becomes 0, and all the game stack areas The RAM parity adjustment data is calculated and set in the game RAM area so that the exclusive OR of the areas (unused area 3, game stack area (unused) and game stack area (in use)) becomes 0 ( Si4) and access to the RAM 41c is prohibited (Si5). Thereafter, the voltage decreases, and the CPU 41a of the main control unit 41 stops and shifts to a standby state. Then, as the voltage decreases while in this standby state, the main control unit 41 is internally in an operation stop state and reliably stops operation in the event of a power interruption.

  In this embodiment, the adjustment data is set in the target area so that the calculation result of the target area in the power interruption process becomes a specific value (0 in this embodiment), and the target data is set in the start process. Whether or not the data in the RAM 41c is normal is determined based on whether or not the calculation result of the area to be a specific value. The calculation result of the area to be processed in the power interruption process and the area to be processed in the start-up process It may be configured to determine whether or not the data in the RAM 41c is normal depending on whether or not the result of the calculation matches. The calculation method is not limited to exclusive OR, and other calculation methods (for example, summation) may be used.

  Further, in this embodiment, RAM parity adjustment data is calculated using data stored in all areas of the game RAM area including the unused area 3 in the power interruption process, and the unused area 3 is included in the activation process. It is determined whether or not the RAM 41c is normal based on the RAM parity calculated using the data stored in all the game RAM areas, and an invalid program is stored in the unused area 3. In this case, since it is determined that the RAM is abnormal, it is possible to prevent an unauthorized program from being stored in the unused area 3.

  In this embodiment, RAM parity adjustment data is calculated using data stored in all areas of the game RAM area including the unused area 3 in the power interruption process, and the unused area 3 is included in the activation process. The RAM parity adjustment of the game RAM area including the unused area 3 is configured to determine whether or not the RAM 41c is normal based on the RAM parity calculated using the data stored in all areas of the game RAM area. Data is calculated and set in the game RAM area, and RAM parity adjustment data in the non-game RAM area is calculated and set in the non-game RAM area, and stored in the game RAM area including the unused area 3 in the startup process. RAM parity calculated using the calculated data and RAM parity calculated using the data stored in the non-game RAM area RAM41c may be determined configure whether normal or not based. In such a configuration, if an illegal program is stored in the game RAM area or the non-game RAM area, it is determined that the RAM is abnormal. Therefore, the illegal program is in either the game RAM area or the non-game RAM area. Can be prevented from being stored.

  In the present embodiment, the main control unit 41 executes the power interruption process when the power supply to the slot machine 1 is stopped and the power interruption detection circuit 48 detects a drop in the power supply voltage. In this case, by prohibiting access to the RAM 41c, access to both the game RAM area and the non-game RAM area is prohibited. It is possible to prevent illegal data from being stored using the area.

  In the slot machine 1 of the present embodiment, by placing the flow path switching plate 147 in the non-guide position, medals inserted from the medal insertion slot 4 flow down to the medal return passage 132 side, while the flow path switching plate 147 is By being positioned at the guide position, a medal selector 29 is provided in which medals inserted from the medal insertion slot 4 flow down to the hopper tank 34a side, and the main control unit 41 sets the flow path switching solenoid 30 to the off state. Thus, while the flow path switching plate 147 is positioned at the non-guide position, the flow path switching plate 147 can be changed to the guide position by turning on the flow path switching solenoid 30.

  In such a configuration, the main control unit 41 controls the on-off state of the flow path switching solenoid 30 to switch the medal flow path of the medal selector 29 to the predetermined flow path side, and performs the previous switching control. If it is configured to perform control to switch the flow path according to the flow path switching status recognized on the basis, if for some reason the recognized switching status and the actual switching status do not match, There is a possibility that the medal channel may not be switched to the predetermined channel side.

  On the other hand, the main control unit 41 of this embodiment, when executing the settlement process, regardless of whether or not the process of setting the flow path switching solenoid 30 to the on state has already been performed. By setting the value of the output port corresponding to the switching solenoid 30 to a value indicating off, the flow path switching plate 147 of the medal selector 29 is positioned at the non-guide position, and the medal flow down passage 133 is switched to the return unit 137 side. Thus, when the settlement process is performed, the medal return passage 132 can be switched to the sure side.

  Further, the main control unit 41 of the present embodiment, when executing the setting confirmation process, regardless of whether or not the process of setting the flow path switching solenoid 30 to the on state has already been performed. By setting the value of the output port corresponding to 30 to a value indicating off, the flow path switching plate 147 of the medal selector 29 is positioned at the non-guide position, and the medal flow path 133 is switched to the return unit 137 side. Thus, when performing the setting confirmation process, the medal return passage 132 can be switched to the sure side.

  In addition, the main control unit 41 of the present embodiment, when executing the start waiting error process, regardless of whether or not the process of setting the flow path switching solenoid 30 to the on state has already been performed. By setting the value of the output port corresponding to the switching solenoid 30 to a value indicating off, the flow path switching plate 147 of the medal selector 29 is positioned at the non-guide position, and the medal flow down passage 133 is switched to the return unit 137 side. Thus, when the error process during start waiting is performed, the medal return path 132 can be switched to the side.

  In addition, the main control unit 41 of the present embodiment clears the insertion possible flag indicating that a medal can be inserted when the respective processes are started in the settlement process, the setting confirmation process, and the waiting-for-start error process. After the medal can not be inserted, the flow path switching solenoid 30 is set to the off state, and the merit of the medal based on the inserted medal sensors 31a to 31c is cleared by clearing the insertable flag. By setting the state where the insertion determination is not performed, it is possible to prevent a medal from being detected unintentionally based on the output of the insertion medal sensor 31.

  In the present embodiment, the main control unit 41 sets the medal insertion determination based on the inserted medal sensors 31a to 31c in a state where the insertable flag is cleared, thereby inserting the medal sensor 31a. Although the medal detection by -c is invalidated, the medal detection by the inserted medal sensors 31a-c may be invalidated when the insertable flag is cleared.

  In addition, the main control unit 41 according to the present embodiment performs insertion availability determination processing for determining whether or not a medal can be inserted at the end of each of the settlement processing, the setting confirmation processing, and the waiting-for-start error processing. If it is possible to insert according to the determination result of the insertion permission / inhibition determination process, the insertion possible flag is set.After that, the insertion determination of the medal is performed and the insertion possible flag is set. When the flow path switching solenoid 30 is set to the on state, the medal flow-down passage 133 is switched to the hopper tank 34a side, and when the flow-down passage 133 is switched to the hopper tank 34a, the medal that flows down It is possible to prevent the battery from flowing down to the hopper tank 34a without making a determination.

  In addition, the main control unit 41 of the present embodiment calls and executes the insertability determination process at the end of the settlement process, the setting confirmation process, and the error process, and executes the bet number, credit value, and bet number value. The sum of the bet number, credit value, and bet number is the maximum medal that can be inserted, while clearing the insertable flag. If the number does not reach the number, the flowable flag is set, and then the determination result in the flowability determination processing, that is, whether the flowable solenoid 30 is set on-off according to whether or not the flowable flag is set. The state is to be switched.

  In particular, after the settlement process is completed, the credit should be 0, and it is not necessary to make the above determination. However, similar to the setting confirmation process and the error process, a common moduleized input availability determination process is executed. By switching the on-off state of the flow path switching solenoid 30 in accordance with the determination result in the availability determination process, the flow path switching solenoid is set after the completion of the settlement process, the setting confirmation process, and the error process. The capacity of the program related to the control for switching 30 can be reduced.

  In the present embodiment, at the end of each of the adjustment process, the setting confirmation process, and the error process, the flowability determination process is executed, and the flow path switching solenoid 30 is turned on according to the determination result in the flowability determination process. -It is a configuration that switches the state of off, but memorize whether or not a medal can be inserted before the start of each process of checkout process, setting check process, error process, checkout process, setting check process, The configuration may be such that the flow path switching solenoid 30 is switched to the on-off state according to the state before the start at the end of each error processing.

  Further, the main control unit 41 according to the present embodiment transmits a command indicating that the corresponding process is started to the sub-control unit 91 when starting the settlement process, the setting confirmation process, and the error process. The sub-control unit 91 notifies that the corresponding process is executed according to the command, so that the medal cannot be inserted when the settlement process, the setting confirmation process, and the error process are performed. The player can be informed that this is possible.

  In addition, the main control unit 41 of the present embodiment sets a detection time invalidation timer when the flow path switching solenoid 30 is switched from on to off, and thereafter, the detection time of the inserted medal sensors 31a to 31c over a predetermined period The medal clogging error is not determined even when the clogging determination time is exceeded, and after the medal flow path is switched from the outlet 142 side to the medal return path 132 side, the inserted medal is momentum and the medal flow path 133 Will flow down to the outlet 142 side, even if the passing speed of the medal is slower than usual, it will not be determined as a medal clogging error, and so-called swallowing of the medal will cause frequent abnormality detection. Can be prevented.

  Further, the main control unit 41 of the present embodiment turns off the turn-on request LED 17 when the flow switching solenoid 30 is turned off when starting the adjustment process, the setting confirmation process, and the error process. Therefore, it is possible to notify the player that the meda cannot be inserted in the settlement process, the setting confirmation process, and the error process.

  The slot machine 1 of the present embodiment includes a medal selector 29 that determines the authenticity of medals inserted from the medal insertion slot 4, and the main control unit 41 passes the medal flow path 133 of the medal selector 29 through the hopper tank. The number of medals guided to the hopper tank 34a is an upper limit value (in this embodiment, the betting number is defined). (The sum of the number and the maximum number of credits), the medal flow path 133 is switched to a flow path that leads to the medal payout exit 9 side, and the main control unit 41 is stored in the bet number or credit After the settlement process for returning medals, the medal flow path 133 is switched to a flow path leading to the hopper tank 34a side.

  In such a configuration, after the settlement is completed, the number of inserted medals should not have reached the upper limit, so if the configuration allows the insertion of medals at the end of the settlement, In the event that credit settlement is not performed normally due to a malfunction, the insertion of medals may be permitted after the settlement is completed, with the number of bets and the number of medals stored in the credit reaching the upper limit. There is.

  On the other hand, the main control unit 41 according to the present embodiment executes the insertion permission / inhibition process for determining whether or not the number of medals stored as credits has reached the upper limit at the end of the settlement process. If it is determined that the number has been reached, the insertable flag is cleared to make it impossible to insert a medal. If it is determined that the upper limit has not been reached, the insertable flag is set. Therefore, even if the checkout process is not performed normally due to a malfunction, the number of medals stored in the credit remains in the state where the upper limit has been reached. It can be prevented that a medal can be inserted after the completion.

  In addition, the main control unit 41 according to the present embodiment determines whether or not the number of medals stored in the credit has reached the upper limit in a plurality of processes such as a settlement process, a setting confirmation process, and a waiting-for-start error process. It is possible to call the insertion permission / inhibition determination process, and the insertion permission / inhibition determination process is included in the game program as a common module that can be called based on various processes. It is possible to reduce the program capacity required for the process of determining whether or not the number of stored medals has reached the upper limit.

  The main control unit 41 of the present embodiment adds one more medal number stored in the credit in the insertion possibility determination process for determining whether the medal number stored in the credit has reached the upper limit number. In this case, a process for determining whether or not the upper limit number is reached is included, so that one more is added in addition to whether or not the bet number or the medal number stored in the credit reaches the upper limit number in the insertion possibility determination process. Thus, it is possible to specify whether or not the upper limit number is reached, and it is possible to make preparations for prohibiting the insertion of medals when it is specified that the upper limit number is reached by adding one more.

  The main control unit 41 is configured to be able to execute an insertion availability determination process for determining whether or not the number of medals stored in the credit has reached the upper limit number, and includes a ROM 41b in which a program and data are stored. The ROM 41b includes a program area (game program area and non-game program area) where the program is stored, and a data area (game data area and non-game data area) where the fixed data used by the program is stored. In the determination process, the upper limit number for determining whether the bet number or the medal number stored in the credit has reached the upper limit number is stored in the data area instead of the program area of the ROM 41b. Even when changing the upper limit number used in judgment processing, only the upper limit number is changed without changing the program. Door can be.

  In addition, when starting the settlement process, the main control unit 41 according to the present embodiment transmits a settlement start command indicating that the settlement process is started to the sub-control unit 91, and the sub-control unit 91 performs the settlement process. Upon receiving the start command, a notice during settlement is made to notify that the settlement process is executed. After the settlement process is finished, the main control unit 41 sets the thrown-in flag in the throw-in / out-of-insertion determination process, After entering the state in which the payment can be made, a settlement end command that can specify that the settlement process is to be ended is transmitted to the sub-control unit 91, and the sub-control unit 91 receives the settlement settlement command and performs settlement. Since the middle notification is terminated, it is possible to prevent the insertion of medals from being restricted even though the settlement notification is terminated. The same applies to the setting confirmation process and the start waiting error process.

  Next, a timer counter for measuring a time interval used by the main control unit 41 for game progress control and the like will be described with reference to FIGS.

  When the timing start condition is satisfied, the main control unit 41 sets an initial value corresponding to the timing time as the timer value of the timer counter assigned to the game RAM area of the RAM 41c, and in the timer interrupt process (main) The timer value is periodically subtracted, and when the timer value becomes 0, it is specified that the time has elapsed.

  Specifically, when a timing start condition is established in the main process, the main control unit 41 sets an initial value of a timer value corresponding to the timing time in an area to which a timer counter corresponding to the condition is assigned. The set timer value is decremented by 1 until it becomes 0 every 2.24 ms in the time counter update process of the timer interrupt process (main).

  In the main process, as shown in FIG. 23, the address of the corresponding timer counter is acquired (Sj1), the acquired value is read (Sj2), and it is determined whether or not the read value is 0 (Sj3). If it is determined that the read value is 0, it is determined that the time has elapsed.

  As shown in FIG. 24, the timer counter used in the present embodiment has an initial value of 1 byte timer A, 1 byte timer B, 1 byte timer C, an initial value exceeding 1 byte, and an initial value exceeding 2 bytes. 2 byte timer A, 2 byte timer B, 2 byte timer C, 2 byte timer D are included.

  The 1-byte timer is a timer for measuring a relatively short period that can be measured with a timer value within 1 byte. For example, an external output signal timer that measures an output period of an external output signal, an LED output update period LED update timer that measures the time, stop invalid timer that measures the period until the stop operation is validated after detection of the stop operation, wait for payout that measures the period until the medal payout starts after the reel stops Timer, insertion detection timer that measures the period from when the insertion medal sensors 31a to 31c are detected, on insertion detection timer that measures the period after the insertion sensor 26 is detected, and on of the payout sensor 34c There is a payout detection timer that measures a period after the detection of the occurrence of a malfunction, a start-up timer that measures a period until the stop operation becomes effective after the reel rotation starts. Among these, the stop invalid timer, the payout waiting timer, and the start timer do not cross the timing at which one game ends, but the external output signal timer, the LED update timer, the input detection timer, the input port The detection timer and the payout detection timer may straddle the timing at which one game ends with the time measured by these timers.

  The 2-byte timer is a timer for measuring a relatively long period that cannot be measured with a timer value within 1 byte. For example, a 1-game time timer that measures a specified time (about 4.1 seconds) required for 1 game. , A security signal timer for measuring the minimum output period of the security signal among the external output signals, a standby time timer for measuring a period from the end of the game, and a hopper empty for measuring a period in which the payout sensor 34c is not detected after the hopper motor 34b is driven. There is a timer. Of these, the waiting time timer and the hopper empty timer do not straddle the timing when one game ends, but the one gaming time timer and the security signal timer have one measuring time measured by these timers. There are times when the timing of the end of.

  As described above, the timer counter is a timing at which one game ends, that is, a timing at which a part of the RAM 41c is initialized as the game progresses (a part of the RAM 41c at the end of one game or at the end of a specific gaming state). Including a timer counter that measures a measurement period spanning the timing at which a part of the RAM 41c is initialized in accordance with the progress of the game. The counter is also assigned to a special work that is not initialized at the timing according to the progress of the game.

  Among these timer counters, the 1-byte timers A to C are allocated to the consecutive 3 byte areas (804CH to 804EH) of the RAM 41c one byte at a time, and the 2-byte timers A to D are the continuous 8-byte RAM 41c. Two bytes are allocated to the area (804FH to 8055h). Further, the 1-byte timers A to C and the 2-byte timers A to D are also assigned to continuous areas of the RAM 41c. Hereinafter, an area to which the 1-byte timers A to C are allocated is referred to as a 1-byte timer group, and an area to which the 2-byte timers A to D are allocated is referred to as a 2-byte timer group. That is, both the 1-byte timer group and the 2-byte timer group are set in an area to which consecutive addresses are assigned according to a predetermined rule. The area to which consecutive addresses are assigned according to a predetermined rule is, for example, an area to which an address added by N (N is a natural number) from the start address and the start address is assigned.

  FIG. 25 is a flowchart showing the control content of the time counter update process.

  In the time counter update process, first, the number of 1-byte timer counters to be updated (3 in this embodiment) is set as the number of processes for 1 byte (Sk1), and the first address of the 1-byte timer group (804CH) is set. A pointer is set (Sk2).

  Next, if the 1-byte value stored in the designated address (address indicated by the pointer) is not 0, the 1-byte value of the designated address is decremented by 1 (Sk3), and the processing count set in the Sk1 step is decremented by 1. (Sk4), it is determined whether or not the number of processes after subtraction is 0 (Sk5).

  When the number of processes after subtraction is not 0 in the step of Sk5, that is, when all the 1-byte timers have not been updated, the pointer is incremented by 1 (Sk6), and the process returns to the step of Sk3. As a result, the pointer moves to the address of the unprocessed 1-byte timer, and if the 1-byte value of the designated address is not 0, the pointer is subtracted.

  When the number of processes after subtraction is 0 in the step of Sk5, that is, when all the 1-byte timers have been updated, the number of 2-byte timer counters to be updated as the number of 2-byte processes (this embodiment) Then, 4) is set (Sk7), and 1 is added to the pointer (Sk8). As a result, the pointer moves to the start address (804FH) of the 2-byte counter group.

  Next, if the 2-byte value stored in the area consisting of the designated address (the address indicated by the pointer) and the next address is not 0, 1 is subtracted from the 2-byte value of the designated address and the next address (Sk9), and Sk7. 1 is subtracted from the number of processes set in step (Sk10), and it is determined whether or not the number of processes after subtraction is 0 (Sk11).

  When the number of processes after subtraction is not 0 in the step of Sk11, that is, when the update of all the 2-byte timers is not completed, 2 is added to the pointer (Sk12), and the process returns to the step of Sk9. As a result, the pointer moves to the address of the unprocessed 2-byte timer, and if the 2-byte value of the designated address and the next address is not 0, the pointer is subtracted.

  If the number of processes after subtraction is 0 in the step of Sk11, that is, if all the 2-byte timers have been updated, the process ends.

  As described above, in this embodiment, the value of the timer counter assigned to the RAM 41c is periodically updated to become a specific value (0), thereby specifying the passage of time. Conventionally, when measuring multiple types of time intervals, timer values are set and updated within multiple types of processing that require timekeeping, and each type of program for updating multiple types of timer values is processed. Since it is necessary to provide it inside, it was a factor which increased program capacity. In addition, since multiple types of timer counters are assigned as data groups for each process used, it is necessary to read out the values of unrelated addresses in order to update all of them in one process. there were.

  On the other hand, in this embodiment, an area in which a plurality of types of timer counter values are stored is set to an area to which consecutive addresses are assigned according to a predetermined rule in the RAM 41c, and the timer value stored in the designated address is Since multiple types of timer values are updated by repeatedly executing the update process while changing the specified address for the area where multiple types of timer counter values are stored by adding a constant to the current specified address Thus, the program capacity can be reduced as compared with the case where each of the processes for designating a plurality of types of addresses and updating the values of the addresses is performed in the individual processes.

  Multiple types of timers can be obtained by repeatedly executing the process of updating the timer value stored at the specified address while changing the specified address for the area where the multiple types of timer counter values are stored by performing a predetermined calculation. Any configuration may be used as long as the value is updated. For example, by adding a constant to the current designated address, multiple types can be obtained by repeatedly executing while changing the designated address for an area in which multiple types of timer counter values are stored. The timer value may be updated, or a value corresponding to the number of processes with respect to the reference address (for example, for a 1-byte counter, +1 for the number of processes 1, +1 for the number of processes 2, and the number of processes While changing the designated address for the area where multiple types of timer counter values are stored by adding or subtracting +3 ...) for 3 Ri may be configured to update a plurality of types of the timer value by return run.

  In the present embodiment, the configuration includes seven types of timer counter values of 1-byte timers A to C and 2-byte timers A to D. However, at least two types of timer counter values are determined according to a predetermined rule of the RAM 41c. In the process of updating the timer value stored in the specified address, the specified address for the area in which multiple types of timer values are stored is changed by performing a predetermined operation. However, if the configuration is such that two or more types of timer values are updated by repeated execution, the program capacity can be reduced as described above.

  In addition, only one of the 1-byte timer and 2-byte timer is set to set the timer counter value in an area to which consecutive addresses are assigned according to a predetermined rule in the RAM 41c, and update the timer value stored in the designated address. A configuration in which a plurality of types of timer values are updated by repeatedly executing a predetermined calculation while changing a designated address for an area in which a plurality of types of timer values are stored may be employed.

  Further, only for some of the timer counters provided in the main control unit 41, a process of setting a timer value in an area to which consecutive addresses are assigned according to a predetermined rule in the RAM 41c and updating the timer value stored in the designated address, A configuration in which a plurality of types of timer values are updated by repeatedly executing a predetermined calculation while changing a designated address for an area in which a plurality of types of timer values are stored may be employed.

  In this embodiment, a separate timer counter is provided for each type of period to be measured. For example, a single timer counter may be shared for a plurality of types of periods in which the measurement periods do not overlap.

  In the present embodiment, the main control unit 41 executes the process according to the timer interruption process (main) for periodically performing a predetermined process regardless of the progress of the game and the progress of the game. A main process that performs different processes in stages, and the main control unit 41 sets an initial value to the timer counter when a timing condition is satisfied in the main process, and a plurality of types of timer interrupt processes (main) The timer value is updated, and it is not necessary to provide a process for updating multiple types of timer values in each process constituting the main process, so the program capacity for updating multiple types of timer values is reduced. be able to.

  In this embodiment, the timer interrupt process (main) is executed by periodically interrupting the main process. However, in the timer interrupt process periodically performed, it is determined in advance regardless of the progress of the game. The main control unit 41 may be configured to perform both a periodic process for performing the processed process and a main process for performing a process that varies stepwise depending on the progress of the game. By setting an initial value to the timer counter when the timing condition is satisfied in the process and updating multiple types of timer values in the periodic process, multiple types of timer values are set in each process constituting the main process. Since it is not necessary to provide a process for updating, it is possible to reduce the program capacity related to updating of a plurality of types of timer values.

  Further, in this embodiment, in the time counter update process, the value of the address is updated on condition that the value of the designated address is not 0, and the timer value is updated to an abnormal value. Can be prevented.

  Further, in this embodiment, in the time counter update process, the number of processes equal to the number of timer counters to be updated is set, and the process of updating the timer value is repeatedly executed for the set number of processes. The number of timer counters to be updated can be easily set. For example, when a plurality of types of timer counters having different update intervals are provided, the type of timer value to be updated can be arbitrarily set according to the number of processes to be set. it can.

  Note that the number of processes, that is, the number of timer counters to be updated may be set in a program, or values set in a table may be read and set.

  In addition, the timer counter to be updated last is set in advance without setting the number of processes at the beginning, and the timer value is updated repeatedly until the address of the timer counter is reached. It is also possible to store a specific end value (for example, FFh) at the next address of the timer counter, and to repeatedly execute the process of updating the timer value until the value read from the specified address becomes the specific end value. good.

  In this embodiment, a 1-byte timer counter and a 2-byte timer counter are provided, and a process for updating a 1-byte timer value and a process for updating a 2-byte timer value are separately provided. Therefore, the capacity of the program and the capacity occupied by the timer value in the RAM 41c can be reduced as compared with the case where the process of updating the 1-byte timer value and the process of updating the 2-byte timer value are made common.

  In this embodiment, a relatively long time corresponding to an initial value exceeding 1 byte is measured by providing a 2-byte timer counter. For example, a timer counter having a different update interval, for example, a timer, is used. Interrupt processing (main) By providing a first timer counter that is updated once every four times and a second timer counter that is updated once every fourteen times, a relative value can be obtained without providing a 2-byte counter. It is also possible to employ a configuration for measuring a long time interval. By doing so, it is not necessary to provide a process for updating a 1-byte timer value and a process for updating a 2-byte timer value. It is possible to reduce the program capacity related to the update.

  In the present embodiment, a plurality of types of timer counters are assigned to special works that are not initialized in accordance with the progress of the game in the RAM 41c, and are not initialized in accordance with the progress of the game. Regardless of the progress of the game, it is possible to measure the time spanning the timing when a part of the RAM 41c is initialized in accordance with the progress of the game.

  In particular, in this embodiment, not only the timer counter that may cross the timing when the measurement period ends in one game, that is, the timing at which a part of the RAM 41c is initialized as the game progresses, Since the timer counter that does not cross over the timing at which a part of the RAM 41c is initialized according to the progress is stored in the area assigned to the special work together with other timer counters, the timer counter can be easily managed. In addition, a timer counter that does not straddle the timing at which a part of the RAM 41c is initialized according to the progress of the game is set, and a timing at which a part of the RAM 41c is initialized at the measurement period according to the progress of the game. The usage of the timer counter can be easily changed by a later design change, such as changing to a timer counter that may straddle. It can be. In addition, as described above, if a single timer counter is shared for a plurality of types of periods in which measurement periods do not overlap, the timing at which a part of the RAM 41c is initialized may be crossed as the game progresses. It is possible to measure the measurement period and the measurement period that does not cross the timing at which a part of the RAM 41c is initialized in accordance with the progress of the game with one timer counter.

  In the above-described embodiment, the example in which the present invention is applied to a slot machine in which bets are set using medals and credits as game values has been described. However, slots for setting bets using game balls as game values. The present invention may be applied to a machine or a fully credit type slot machine that sets a bet amount using only credit as a gaming value. When using a game ball as a game value, for example, one medal can correspond to five game balls, and when 3 is set as the number of bets in the above embodiment, 15 game balls are used. This is equivalent to setting the number of bets using.

  Further, the present invention is not limited to the use of only one of a plurality of types of game values such as medals and game balls, for example, a combination of a plurality of types of game values such as medals and game balls.
