Description

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

  Conventionally, in this type of slot machine, an internal lottery is performed to determine whether or not a prize is allowed to occur almost simultaneously with the start of the game, and the winning of the winning prize is allowed on the condition that the prize is won What is done is common. Also, at amusement stores that operate with slot machines installed, it is necessary to change the stage of winning probability of the installed slot machines in order to adjust sales. A setting value, which is a value indicating the stage of the winning probability applied as the lottery probability of the internal lottery, can be selected and set from a plurality of values having different probabilities by an operation of an employee or the like.

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

  For this reason, in the conventional slot machine, when an abnormality occurs in the memory data, the memory data is initialized, and the set value includes a predetermined set value (for example, a winning probability with a payout rate close to 100%). And a setting value that determines the winning probability at which the payout rate is the lowest) are automatically set to return to a state in which the game can proceed (see, for example, Patent Documents 1 and 2).

  On the other hand, for this type of slot machine, every time one game is finished, data that does not need to be carried over to the next game among data stored in the memory installed in the control unit (for example, winning prizes that are not carried over to the next game). It has been proposed to initialize a winning flag, the number of medals inserted, etc.) and shift to the next game (see, for example, Patent Document 3).

  Also in the pachinko machine, the variable display device for controlling the variable display device has a storage area for storing data corresponding to each display area constituting the variable display device, and at the end of the variable display (from the main control means) It has been proposed to initialize the data stored in the storage area described above (when a confirmation command is received) (see, for example, Patent Document 4).

JP-A-6-114140 JP 2000-296200 A JP 2001-79157 A JP 2002-35318 A

  In the slot machines as described in Patent Documents 1 and 2, when an abnormality occurs in the data in the memory, the setting value is selected and set by the operation of an amusement shop employee or the like as described above. Rather than automatically setting a predetermined set value and returning to a state in which the game can proceed, it is originally based on the set value selected and set by the operation of the amusement store Preliminary settings automatically set by the slot machine control when abnormalities occur in the memory data even though the internal lottery should be performed with the winning probability applied and the occurrence of winnings should be allowed An internal lottery will be performed by applying a winning probability based on the value. In other words, the game should be played based on the setting value automatically set by the slot machine due to a malfunction of the slot machine, where the game should be played based on the setting value selected by the game shop side. There was a problem that the fairness of the game was lost.

  On the other hand, in the slot machine described in Patent Document 3, every time one game is completed, data stored in the memory that is not required to be carried over to the next game is initialized, but the memory storage area is not yet stored. A storage area in use (a storage area that is not used at all by design or an unused area in a stack) is not periodically initialized. For this reason, by locating an unauthorized program in an unused area of these memories, the original program (stored in the ROM) is somehow triggered (for example, an operation is performed with a procedure that is unlikely to be performed normally). There is a risk of fraud such as causing the gaming machine to perform an operation different from that of the program.

  The present invention has been made paying attention to such problems, and it is possible to achieve fairness of the game, and there is an illegal program in an unused area of the storage means installed in the control unit that controls the game.

The hopper motor 34 is connected, and these electric components are driven based on control of a main control unit 41 described later mounted on the game control board 40.

  The game control board 40 is composed of a microcomputer having a CPU 41a, ROM 41b, RAM 41c, and I / O port 41d. The main control unit 41 for controlling the game, random numbers in a predetermined range (0 to 16383 in this embodiment) are used. A random number generation circuit 42 for generating, a sampling circuit 43 for acquiring a random number from the random number generation circuit, and a switch detection circuit 44 for detecting a detection signal input from switches connected to the game control board 40 directly or via the power supply board 100 , A motor driving circuit 45 that controls the driving of the reel motors 32L, 32C, and 32R, a solenoid driving circuit 46 that controls the driving of the flow path switching solenoid 30, and a driving control of various displays and LEDs connected to the game control board 40. The power supply voltage supplied to the LED drive circuit 47 and the slot machine 1 to be monitored is monitored. An interruption detection circuit 48 that outputs a voltage drop signal indicating that to the main control unit 41 when a drop is detected. When the power is turned on or when an initialization command from the CPU 41a is not inputted, a reset signal is sent to the CPU 41a. A reset circuit 49 to be applied and other various devices and circuits are mounted.

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

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

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

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

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

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

  As the RAM 41c, a DRAM (Dynamic RAM) is used, and a refresh operation is required to maintain the stored data contents. The CPU 41a is provided with a refresh register 41R (see FIG. 53) for performing this refresh operation. The refresh register 41R is composed of 8 bits, and the lower 7 bits are automatically incremented every time the CPU 41a fetches an instruction from the ROM 41b. The value is updated every execution time of one instruction. Is called.

  The main control unit 41 is also supplied with backup power even during a power failure, and while the backup power is being supplied, the CPU 41a performs a refresh operation to hold the data stored in the RAM 41c. It is like that.

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

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

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

  Similar to the main control unit 41, the effect control board 90 includes a microcomputer having a CPU 91a, ROM 91b, RAM 91c, and I / O port 91d. The effect control board 90 includes a sub control unit 91 for effect control and an effect control board 90. A liquid crystal driving circuit 92 that controls the driving of the connected liquid crystal display 51, a lamp driving circuit 93 that controls the driving of the effect LED 52, an audio output circuit 94 that controls audio output from the speakers 53 and 54, A reset circuit 95 that gives a reset signal to the CPU 91a when the initialization command from the CPU 91a is not input, and other circuits are mounted. The CPU 91a receives a command transmitted from the game control board 40 and produces an effect. While performing various controls to perform, each control circuit mounted on the production control board 90 The directly or indirectly controlled.

  Similar to the CPU 41a of the main control unit 41, the CPU 91a has an interrupt function (including an interrupt prohibition function) such as a timer interrupt. An interrupt terminal (not shown) of the sub-control unit 91 is connected to a strobe (INT) signal line that is output when the main control unit 41 transmits a command among command transmission lines. An interrupt is generated based on the input, and a command reception interrupt process to be described later is executed. The CPU 91a executes a timer interrupt process (sub) to be described later by generating an interrupt every time the number of clock inputs reaches a certain number, that is, every certain interval. Also, when an unused interrupt occurs in the CPU 91a, an unused interrupt process for immediately returning to the original process is executed.

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

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

  4 is a circuit diagram for explaining the configuration of the power supply board 100, and FIG. 5A is a circuit diagram for explaining the configuration around the main control unit 41 in the game control board 40. (B) is a circuit diagram for explaining a configuration around the sub-control unit 91 in the effect control board 90.

  As shown in FIG. 4, a rectifier circuit 302, a transformer 304, and voltage generation circuits 303, 305 to 308 are mounted on the power supply substrate 100. The rectifier circuit 302 converts an AC 100V AC voltage supplied from the outside into a DC voltage, and the transformer 304 transmits the DC voltage converted by the rectifier circuit 302 to an internal circuit. Then, the voltage generation circuit 303 generates + 25V DC voltage from the DC voltage transmitted through the transformer 304 and outputs it to the connector 301 and the voltage generation circuits 305, 306, 307, and 308, respectively. The voltage generation circuits 305, 306, 307, and 308 generate +24 V, +12 V (VCC), +12 V, and +5 V DC voltages from the +25 V DC voltage generated by the voltage generation circuit 303 and output them to the connector 301. . The connector 301 is connected to the game control board 40 or the like, and the DC voltage generated by the voltage generation circuits 305, 306, 307, and 308 is a device mounted on the game control board 40 or the effect control board 90, the game control board 40, It is supplied as a power source for driving various electrical components connected to the effect control board 90. That is, the + 25V DC voltage generated by the voltage generation circuit 303 drives various devices mounted on the game control board 40 and the effect control board 90, and various electrical components connected to the game control board 40 and the effect control board 90. It is a generation source of power.

  Among the DC voltages supplied from the power supply board 100, + 24V DC voltage is used as a driving power source for the hopper motor 34 directly connected to the power supply board 100, and is supplied to the game control board 40, thereby playing the game control board 40. It is also used as a drive power source for electrical components such as the reel motors 32L, 32C, 32R and the flow path switching solenoid 30 connected to the. Also, a + 12V (VCC) DC voltage is supplied to the effect control board 90 via the game control board 40, which will be described later, which is a drive power source for devices mounted on the effect control board 90 such as the sub-control unit 91. It is used as a power source for +5 V (VCC), or as a driving power source for electrical components such as the liquid crystal display 51, LEDs, and speakers connected to the effect control board 90. Further, the + 12V DC voltage is supplied to the game control board 40 and is connected to the game control board 40 via the power supply board 100 and other electrical components such as LEDs, indicators, sensors, and switches. It is used as a drive power source for electric switches (including electrical parts such as switches). The + 5V DC voltage is supplied to the game control board 40 and used as a drive power source for devices mounted on the game control board 40 such as the main control unit 41.

  Further, the + 5V DC voltage supply line in the game control board 40 branches on the game control board 40 to form a + 5V (VBB) DC voltage supply line, as shown in FIG. The + 5V (VBB) DC voltage supply line is connected to the backup power supply input terminal VBB via a backflow prevention diode 312 and, as shown in FIG. A large-capacitance capacitor 310 is provided between them. As a result, a DC voltage of + 5V (VBB) can be stored in the capacitor 310, and even during a power failure, the voltage stored in the capacitor 310 can be supplied as a backup power source over the period until the voltage is completely discharged. It has become.

  In addition, among the DC voltages output from the power supply substrate 100, a DC voltage of + 25V, that is, a DC voltage serving as a source for generating + 24V, + 12V (VCC), + 12V, and + 5V DC voltages is 5 ( As shown in a), the pressure is reduced by the resistor 311 (about 6.6% in this embodiment), and is input to the monitoring voltage input terminal VSB provided in the power interruption detection circuit 48. The power interruption detection circuit 48 outputs a voltage drop signal from the voltage drop signal output terminal RESET when the voltage input to the monitoring voltage input terminal VSB becomes a predetermined level (+1.2 V in this embodiment) or less. It is configured to output. The voltage drop signal output terminal RESET is connected to the trigger terminal CLK / TRG of the main control unit 41 as described above, and when the voltage input to the monitoring voltage input terminal VSB becomes a predetermined level or less. The voltage drop signal is input to the trigger terminal CLK / TRG of the main control unit 41. That is, the CPU 41 a of the main control unit 41 can detect the occurrence of power interruption based on the input of the voltage drop signal from the power interruption detection circuit 48 and can execute a power interruption interrupt process to be described later. In this embodiment, when the + 25V DC voltage becomes about + 18V or less, the voltage reduced by the resistor 311 becomes + 1.2V or less and a voltage drop signal is output. Therefore, the CPU 41a is based on the input of the voltage drop signal. Thus, the occurrence of power interruption can be detected when the + 25V DC voltage becomes + 18V or less.

  Further, the voltage drop signal output terminal RESET branches in the middle and is also connected to the signal input terminal DATA of the main control unit 41, so that the voltage input to the monitoring voltage input terminal VSB becomes a predetermined level or less. Sometimes, the voltage drop signal is input to the signal input terminal DATA in addition to the trigger terminal CLK / TRG of the main control unit 41. In addition, the power interruption detection circuit 48 becomes inoperable or the voltage is not supplied after the voltage input to the monitoring voltage input terminal VSB becomes a predetermined level (+1.2 V) or less. The voltage drop signal is continuously output until it exceeds a predetermined magnitude (+1.2 V). Therefore, the CPU 41a can monitor the input state of the voltage drop signal even during the power interruption interrupt process based on the input of the voltage drop signal from the power interruption detection circuit 48.

  As described above, in this embodiment, the main control unit 41 and the power interruption detection circuit 48 are driven by the + 5V DC voltage generated by the voltage generation circuit 308, and the power interruption detection circuit 48 is connected to the voltage generation circuit 303. When the + 25V DC voltage generated by the above becomes + 18V or less, which is higher than + 5V for driving these devices, the occurrence of power interruption is detected and a voltage drop signal is output. Since the DC voltage of + 5V is supplied to the main control unit 41 for a while after the CPU 41a detects the occurrence of the power interruption, it is necessary for the CPU 41a to perform the power interruption interrupt process based on the input of the voltage drop signal. Enough time can be secured.

  In the present embodiment, the power interruption detection circuit 48 monitors the drop of + 25V DC voltage generated by the voltage generation circuit 303 and is connected to the power supply board 100, the game control board 40 and the effect control board 90. The power supply voltage for driving the electrical components is generated by the voltage generation circuits 305, 306, and 307 provided separately from the voltage generation circuit 303 that generates the + 25V DC voltage monitored by the power interruption detection circuit 48. Since a stable voltage is monitored by the power interruption detection circuit 48 in comparison with a power supply voltage that tends to decrease depending on the driving state of these electric components, the occurrence of power interruption occurs due to a temporary voltage drop. Can be detected, and malfunction such as power interruption interrupt processing can be prevented.

  Further, as shown in FIG. 4, a capacitor 309 is provided on a + 25V DC voltage line input to the voltage generation circuit 306 in the power supply substrate 100, and is supplied to the voltage generation circuit 306 from the + 25V DC voltage. Even when the voltage can be stored and the supply of voltage from the voltage generation circuit 303 is interrupted, +12 V (VCC) is generated for the voltage generation circuit 306 over the period until the voltage stored in the capacitor 309 is discharged. The voltage required to do this is supplied. Therefore, the voltage generation circuit 306 is a source of power for devices such as the sub-control unit 91 mounted on the effect control board 90 for a certain period of time even when the supply of voltage from the voltage generation circuit 303 is interrupted during a power failure. The + 12V (VCC) DC voltage supply can be maintained, and the devices mounted on the production control board 90, in particular the sub-control unit 91, can be replaced by the devices mounted on the game control board 40 during a power failure. It can be driven for a long time. In this embodiment, the sub-control is performed for at least 20 ms from the time when the power interruption detection circuit 48 outputs a voltage drop signal at the time of a power failure as the capacitor 309, that is, from the time when the + 25V DC voltage becomes + 18V or less. A capacitor having a capacity capable of maintaining the drive of the unit 91 is used.

  Further, in the effect control board 90, as shown in FIG. 5B, voltage generation for generating + 5V (VCC) from a + 12V (VCC) DC voltage supplied from the power supply board 100 via the game control board 40 is performed. The circuit 313 is provided, and the + 5V (VCC) DC voltage generated by the voltage generation circuit is supplied to various devices mounted on the effect control board 90, such as the sub-control unit 91, and is used as a drive power source for these devices. used.

  The supply line of the + 5V (VCC) DC voltage to the sub-control unit 91 is connected to the backup power supply input terminal VBB of the sub-control unit 91 via the backflow prevention diode 314 and to the ground level. A large-capacity capacitor 315 is provided between them. As a result, a DC voltage of +5 V (VCC) can be stored in the capacitor, and even during a power failure, the voltage stored in the capacitor 315 can be supplied as a backup power source for a period until the voltage is completely discharged. ing.

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

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

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

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

  In the slot machine 1 according to the present embodiment, the prescribed number of bets that can be set according to the gaming state is determined as described above, and the prescribed number of bets that are determined according to the gaming state is set. It becomes possible to start the game on the condition. In this embodiment, as will be described later, there are a regular bonus, a small role game in a big bonus, and a normal gaming state as a gaming state. Among these, 1 is defined as the prescribed number of bets corresponding to the regular bonus. The prescribed number of bets corresponding to the small role game and the normal gaming state is set to 3. Therefore, when the gaming state is a regular bonus, the game can be started when 1 is set as the bet number, and when the gaming state is the small role game or the normal gaming state, 3 is set as the bet number. Then, the game can be started. In this embodiment, when a specified number of bets corresponding to the gaming state is set, all winning lines L1 to L5 are activated, and the specified number corresponding to the gaming state is If it is 1, all winning lines L1 to L5 are activated when 1 is set as the bet number, and if the specified number is 3 according to the gaming state, 3 is set as the bet number. All winning lines L1 to L5 are activated.

  In the slot machine 1 of this embodiment, when all the reels 2L, 2C, and 2R are stopped, if a combination of symbols called “combinations” is arranged on the activated winning line (hereinafter referred to as an effective line), Become. The type of winning combination is determined according to the game state, but it can be roughly divided into a small role with payout of medals and a replay that can start the next game without the need to set the number of bets. There are a game combination and a special combination with a transition of the game state. In order for each winning 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 for the winning combination.

  Of the winning flags for each of the winning combinations, the winning flag for the small role and the replaying role is valid only in the game in which the flag is set and is cleared at the end of the game. Is valid until a combination of combinations permitted by the flag is completed, and is cleared in a game having a combination of combinations permitted. In other words, once the winning flag for the special role is won, even if the combination of the characters allowed by the flag cannot be aligned, the winning flag is not cleared and it is carried over to the next game. Become. However, as will be described later, the combination of JACIN among the special roles will always be aligned with the winning game, so it will not be carried over to the next game, only the winning flags of other special roles will be If the combination of allowed combinations is not complete, it will be carried over to the next game.

  FIG. 6A is a diagram showing a winning combination table by gaming state. The gaming state winning combination table is stored in advance in the ROM 41b of the main control unit 41 and is used to determine the combination determined to be winning in the internal lottery. The combination determined according to the game state is shown. The role in this slot machine 1 is JAC, Cherry, Watermelon, Bell as a small role, Replay as a replaying role, Big bonus (1), Big bonus (2), Big bonus (3), Regular bonus as special roles (1), regular bonus (2), and JACIN are defined.

  In the regular bonus game state, JAC, cherry, watermelon, and bell, which are small roles, are determined as winning roles, and are subject to lottery in the internal lottery in the regular bonus. In the small bonus game, which will be described later of the big bonus, cherry, watermelon and bell, which are small roles, and regular bonus (2), which is a special role, and JACIN are determined as winning roles. It is targeted. In the normal gaming state, the small role cherry, watermelon and bell, replay role replay, special role big bonus (1), big bonus (2), big bonus (3), regular bonus (1) It is determined as a winning combination and is subject to lottery in the internal lottery in the normal gaming state.

  In this embodiment, in the regular bonus game state, in addition to cherry, watermelon and bell, JAC is defined as a small role for winning. However, in the regular bonus game state, a small role game or a normal game is also provided. Similarly to the state, only cherry, watermelon and bell may be determined as winning small prizes.

  JAC is awarded when the combination of “Bell-JAC-JAC” is aligned on the active line in the regular bonus. However, in the gaming state other than the regular bonus, even if this combination is aligned, JAC is not awarded. Cherry is awarded when the symbol “cherry” is derived to any of the active lines for the left reel 2L in any gaming state. A watermelon is awarded when a combination of “watermelon-watermelon-watermelon” is aligned on any of the active lines in any gaming state. A bell is awarded when a combination of “bell-bell-bell” is arranged on any of the active lines in any gaming state. The payout of medals when these small roles are won will be described later.

  Replay is awarded when a combination of “JAC-JAC-JAC” is available on any of the active lines in the normal gaming state, but this combination is used for regular bonuses and big bonuses (small-games and regular bonuses). Even if it is complete, it will not be a replay prize. When a replay is won, the medals will not be paid out, but the next game can be started without setting the number of bets again, so the number of bets no longer required to be set in the next game (the regular bonus will not be replayed and will always be 3) This is substantially the same as when three corresponding medals are paid out.

  The big bonus is a combination of “red 7-red 7-red 7”, a combination of “white 7-white 7-white 7”, or “blue 7-blue 7-blue 7” in any of the active lines in the normal gaming state. ”Will be awarded when the combination is complete. When the big bonus is won, the gaming state shifts to the big bonus. In the big bonus, a game called a small role game can be played. While the game state is the big bonus, the big bonus medium flag is set in the RAM 41c. The big bonus ends when the total number of medals paid out to the player in the big bonus reaches 465.

  When it is necessary to distinguish between a big bonus by “Red 7-Red 7-Red 7”, a big bonus by “White 7-White 7-White 7”, and “Blue 7-Blue 7-Blue 7” These are referred to as big bonus (1), big bonus (2), and big bonus (3), respectively. The big bonuses (1) to (3) are further subdivided according to the order in which the winning is determined in the internal lottery. When these are distinguished, the big bonus (1) -A Big Bonus (1) -B, Big Bonus (1) -C, Big Bonus (2) -A, Big Bonus (2) -B, Big Bonus (2) -C, Big Bonus (3) -A, Big The bonus (3) -B and the big bonus (3) -C shall be called.

  The regular bonus is awarded when a combination of “BAR-BAR-BAR” is arranged on any of the active lines in the small role game and the normal gaming state. When the regular bonus is won, the gaming state shifts from the small role game or the normal gaming state to the regular bonus. The regular bonus ends when 12 games are consumed, or when 8 games are won (any kind of combination is possible), whichever comes first. While the game state is in the regular bonus, the regular bonus medium flag is set in the RAM 41c. In particular, when a regular bonus is won in the small role game, a regular bonus is provided during the big bonus, and the regular bonus medium flag is also set in the RAM 41c in addition to the big bonus medium flag. When the total number of medals paid out to the player in the big bonus reaches 465 with the regular bonus in the big bonus, the regular bonus is terminated together with the big bonus.

  In addition, when it is necessary to distinguish between the regular bonus due to “BAR-BAR-BAR” in the normal gaming state and the regular bonus due to “BAR-BAR-BAR” in the small role game in the big bonus, the regular bonus (1) respectively. This is called regular bonus (2). In addition, the aforementioned big bonus (1), big bonus (2) and big bonus (3), regular bonus (1) and regular bonus (2) may be collectively referred to as “bonus”. To do.

  JACIN wins when a combination of “Watermelon-JAC-JAC” is available on any of the active lines in the small role game, but in a gaming state other than the small role game, even if this combination is available, JACIN wins. Not. When winning JACIN, the above-described regular bonus is provided during the big bonus, and the regular bonus medium flag is also set in the RAM 41c of the main control unit 41 in addition to the big bonus medium flag. When the total number of medals paid out to the player in the big bonus reaches 465 with the regular bonus in the big bonus, the regular bonus is terminated together with the big bonus.

  Hereinafter, the internal lottery will be described. In the internal lottery, it is determined whether or not the winning of each winning combination is allowed before the display results of all the reels 2L, 2C and 2R are derived and displayed (actually, when the start switch 7 is detected). Is. In the internal lottery, first, a random number for internal lottery (an integer from 0 to 16383) is acquired as described later. Then, for each combination determined according to the gaming state, the acquired internal lottery random number, the bet number set by the player, and the set value set by the reset / setting switch 38 It is performed according to the number of judgment values for the combination. In this embodiment, since the lottery for the small role and the re-playing role and the lottery for the special role are performed separately in the normal gaming state, the winning in the internal lottery is not exclusive, Special roles may be won at the same time.

  In the regular bonus and the small bonus game in the big bonus, the reference of the combination according to the gaming state is performed based on the winning combination table according to the gaming state shown in FIG. This is performed based on both the gaming state winning combination table shown in FIG. 6A and the special combination table shown in FIG. 6C which will be described later.

  When the gaming state is a regular bonus (including the case where it is provided during the big bonus), JAC, cherry, watermelon, and bell are sequentially read out as the target for internal lottery with reference to the winning combination table by gaming state, When the gaming state is a small role game with a big bonus, cherry, watermelon, bell, regular bonus (2), and JACIN are sequentially read out as internal lottery target roles. However, when the regular bonus winning flag (2) is set in the game before the previous time and the game is carried over without winning based on the flag, the regular bonus (2) and JACIN are not subject to the internal lottery.

  When in the normal gaming state, first, a lottery for a small combination and a re-playing combination is performed, and then a special combination is selected. In the lottery for the small role and the re-playing role, refer to the winning role-specific winning table, and in the normal gaming state, the target small role and the re-playing role, i.e., cherry, watermelon, bell, and replay are sequentially selected as the internal drawing. Read out.

  In the lottery of special roles, refer to the winning status table for each gaming state and the special role table for the special role. It is read in the order registered in another table.

  In addition, in the lottery for special roles, it is determined whether or not the special role is lost while winning is determined for a plurality of special roles. The roles and special roles are registered in the order in which they are judged. For this reason, in the special role lottery, the special combination and the special combination losing are read out in the order registered in the special-function-specific table.

  As shown in FIG. 6 (c), in the special role-specific table, the big bonus (1) -A, the big bonus (2) -A, and the big bonus are shown as special bonuses to be selected in the normal gaming state. (3) -A, big bonus (1) -B, big bonus (2) -B, big bonus (3) -B, big bonus (1) -C, big bonus (2) -C, big bonus (3 ) -C, regular bonus (1) is registered, and between big bonus (3) -A and big bonus (1) -B, big bonus (3) -B and big bonus (1) -C In the meantime, since Loss-A and Loss-B are respectively registered, in the special role lottery, Big Bonus (1) -A, Big Bonus (2) -A, Big Bonus (3) -A, Loss- A, Big Bo Eggplant (1) -B, Big Bonus (2) -B, Big Bonus (3) -B, Loss-B, Big Bonus (1) -C, Big Bonus (2) -C, Big Bonus (3) -C The regular bonus (1) is read out in this order.

  However, in the game before the previous game, the winning flag of regular bonus (1), big bonus (1), big bonus (2) or big bonus (3) is set and it is carried over without winning based on the flag. Sometimes, the regular bonus (1) and the big bonuses (1) to (3) are not subject to the internal lottery, so that the special combination lottery is not performed.

  In the internal lottery, the number of determination values determined for the internal lottery target combination is sequentially added to the internal lottery random number, and when the addition result overflows, it is determined that the winning combination is won. When the winning is determined, the winning flag of the combination is set in the RAM 41c of the main control unit 41. The determination value number is read according to the storage address of the determination value number registered in the role-specific table stored in advance in the ROM of the main control unit 41.

  Also, especially in the normal gaming state, when the number of judgment values determined for the small role and the re-playing role that are the target in the normal gaming state is sequentially added to the random number for internal lottery, and the result of the addition overflows It is determined that the winning combination has been won, and the winning flag of the winning combination is set.

  Furthermore, regardless of whether or not the result of the addition of the random numbers for internal lottery overflowed, the number of judgment values determined for the special role that is the target in the normal gaming state (the judgment value that was determined in response to the special role lost) Is added to the random number for internal lottery (the first acquired random number) before addition, and when the result of addition overflows, it is determined that the winning combination is won, and the winning flag of the winning combination is determined. Is set (this is not the case when the result of adding the number of judgment values determined corresponding to the special role loses overflows). That is, in the normal gaming state, both the lottery for the small combination and the re-game combination and the lottery for the special combination are performed based on the same random number for internal lottery.

  As described above, in a state where the winning flag of the regular bonus (1), the big bonus (1), the big bonus (2) or the big bonus (3) is carried over from the previous game to the previous game. If so, there will be no special drawing.

  FIG. 6B is a diagram illustrating an example of a role-specific table for a small role and a re-playing role, and FIG. 6C is a diagram illustrating an example of a role-specific table for a special role (and lose). is there. The number of determination values may be 256 or more, and cannot be stored in one byte. Therefore, each determination value number is registered using a storage area of two bytes.

  The number of determination values for each combination (and lose) is registered corresponding to the number of bets (BET) set by the player in the game. This is because even with the same combination, the winning probability in the regular bonus may differ from other combinations. In addition, the number of determination values corresponding to the number of bets for each combination (and lose) is common regardless of the set value, and is different depending on the set value. If the number of determination values is common regardless of the set value, a common flag is set (value is set to “1”).

  In the role-specific table for the small role and the replaying role, as shown in FIG. 6B, the storage addresses of the JAC, cherry, watermelon, bell, and replay determination value numbers are registered in the order of reference. .

  The JAC is a role that is subject to internal lottery only with the regular bonus, and the storage address of the number of determination values corresponding to the bet number 1 with the regular bonus is registered. The common flag for this combination is 1, and a common storage address for the number of determination values is registered regardless of the set value.

  Cherry, watermelon, and bell are the targets that are subject to internal lottery in any gaming state, and the storage address of the number of judgment values corresponding to the bet number 1 in the regular bonus and the betting in the normal gaming state or small role game A storage address of the number of determination values corresponding to Equation 3 is registered. For cherry and watermelon, the common flag is 1, and a storage address for the common number of determination values is registered corresponding to the number of bets regardless of the set value. For the bell, the common flag is 0, and the storage address of the number of determination values is individually registered according to the set value corresponding to each bet number.

  Replay is a role that is subject to internal lottery only in the normal gaming state, and a storage address for the number of determination values corresponding to the bet number 3 in the normal gaming state is registered. The common flag for this combination is 1, and a common storage address for the number of determination values is registered regardless of the set value.

  As shown in FIG. 6 (c), the special role (and lose) role-specific table includes a big bonus (1) -A, a big bonus (2) -A, a big bonus (3) -A, and a loser. A, Big Bonus (1) -B, Big Bonus (2) -B, Big Bonus (3) -B, Loss-B, Big Bonus (1) -C, Big Bonus (2) -C, Big Bonus (3 ) -C, regular bonus (1), regular bonus (2), and JACIN are stored in the order of the storage values for the number of judgment values for each combination.

  Big Bonus (1) -A, Big Bonus (2) -A, Big Bonus (3) -A, Loss-A, Big Bonus (1) -B, Big Bonus (2) -B, Big Bonus (3)- B is a role that is an object of the internal lottery only in the normal gaming state, and the storage addresses of the number of determination values corresponding to the number 3 of bets in the normal gaming state are respectively registered. For these combinations, the value of the common flag is 1, and the storage address of the common determination value number is registered regardless of the set value.

  Loss-B, Big Bonus (1) -C, Big Bonus (2) -C, Big Bonus (3) -C, Regular Bonus (1) are roles that are subject to internal lottery only in the normal gaming state, The storage addresses for the number of determination values corresponding to the bet number 3 in the normal gaming state are registered. For these combinations, the value of the common flag is 0, and the storage address of the number of determination values is individually registered according to the set value.

  Regular bonus (2) and JACIN are internal lottery targets only in the small bonus game in the big bonus, and the storage address of the number of judgment values corresponding to the bet number 3 in the small bonus game is registered. . The value of the common flag for this role is 1, and a storage address for a common number of determination values is registered regardless of the set value.

  Also, the number of medals to be paid out when winning each winning combination is registered in the role-specific table. However, only the JACs, cherries, watermelons, and bells, which are small roles, are the targets for paying out medals when winning a prize. Cherry, watermelon and bell can be awarded when the bet number is 1 (regular bonus) or 3 (game state other than the regular bonus), but for the bell, when the bet number is 1, That is, when the gaming state is a regular bonus, 15 medals that are more than the other 8 are paid out.

  Big Bonus (1), Big Bonus (2), Big Bonus (3), Regular Bonus (1), Regular Bonus (2), and JACIN winnings are accompanied by a transition of the gaming state, and medals are paid out. It will not be. Replay does not involve the payout of medals. However, since it is not necessary to insert medals used for setting the number of bets in the next game, it is substantially the same as paying out 3 medals. Of course, losing special roles are not eligible for medal payout.

  FIG. 7 is a diagram illustrating a storage area for the number of determination values acquired based on addresses registered in the role-specific table. The storage area for the number of determination values is provided in the RAM 41c of the main control unit 41 in the development model, and in the address area allocated to the ROM 41b in the main control unit 41 in the mass production model.

  For example, the addresses ADD, ADD + 34, ADD + 36, ADD + 38, ADD + 40, ADD + 42, ADD + 44, ADD + 46, ADD + 48, ADD + 110, and ADD + 112 are subject to internal lottery in JAC, replay, big bonus (1) -A, big bonus (2)- Set when A, Big Bonus (3) -A, Loss-A, Big Bonus (1) -B, Big Bonus (2) -B, Big Bonus (3) -B, Regular Bonus (2), JACIN The addresses are referenced regardless of the value, and 27, 2245, 2, 2, 2, 263, 4, 4, 4, 32, 4311 are acquired as the number of determination values, respectively, regardless of the set value.

  The address ADD + 98 is an address that is referred to when the target character of the internal lottery is the regular bonus (1) and the set value is 1, and at this time, 31 stored as the value is acquired as the number of determination values. Is done. Addresses ADD + 100, ADD + 102, ADD + 104, ADD + 106, and ADD + 108 are addresses that are referenced when the internal lottery is a regular bonus (1) and the set value is 2-6. As for regular bonus (1), the number of judgment values is individually stored according to the set value, but since the same number of judgment values is stored, the winning of regular bonus (1) at any set value Probabilities are the same.

  Addresses ADD + 50, ADD + 52, ADD + 54, ADD + 56, ADD + 58, and ADD + 60 are addresses that are referred to when the internal lottery target role is Lost-B and the set value is 1 to 6, respectively. Addresses ADD + 62, ADD + 64, ADD + 66, ADD + 68, ADD + 70, and ADD + 72 are addresses that are referenced when the internal lottery target role is the big bonus (1) -C and the set value is 1-6. Addresses ADD + 74, ADD + 76, ADD + 78, ADD + 80, ADD + 82, and ADD + 84 are addresses that are referenced when the internal lottery target role is the big bonus (2) -C and the set value is 1-6. Addresses ADD + 86, ADD + 88, ADD + 90, ADD + 92, ADD + 94, and ADD + 96 are addresses that are referenced when the internal lottery target is a big bonus (3) -C and the set value is 1-6. For lose-B, big bonus (1) -C, (2) -C, (3) -C, the number of determination values is stored individually according to the set value, and different numbers of determination values are stored. Therefore, the winning (special role losing) probabilities of the loss-B, big bonus (1) -C, (2) -C, and (3) -C will differ depending on the set value.

  The address ADD + 2 is an address that is referred to regardless of the set value when the bet number is 1, that is, in the regular bonus, the target combination of the internal lottery is cherry. The address ADD + 4 is an address that is referred to regardless of the set value when the number of bets is 3, that is, in the normal gaming state or in the small role game, when the target character of the internal lottery is cherry. The number of determination values for cherry is registered according to the number of bets, but since the same value is registered, the winning probability of cherry is the same in any gaming state. For the watermelon, the number of determination values is registered in the same manner at addresses ADD + 6 and ADD + 8.

  Addresses ADD + 10, ADD + 12, ADD + 14, ADD + 16, ADD + 18, and ADD + 20 are addresses that are referenced when the bet number is 1, that is, when the target character of the internal lottery is a bell and the set value is 1 to 6 in the regular bonus is there. Since the same value is registered in each of the addresses ADD + 10 and ADD + 12, ADD + 14 and ADD + 16, and ADD + 18 and ADD + 20, the set value 1 and the set value 2, the set value 3 and the set value 4, and the set value are set at the regular bonus time. With 5 and the set value 6, the winning probability of the bell is the same.

  Addresses ADD + 22, ADD + 24, ADD + 26, ADD + 28, ADD + 30, and ADD + 32 are each when the number of bets is 3, that is, when the target lot of the internal lottery is a bell and the set value is 1 to 6 in the normal game state or the small role game The address to be referenced. Since different values are registered in the addresses ADD + 22, ADD + 24, ADD + 26, ADD + 28, ADD + 30, and ADD + 32, the winning probability of the bell differs depending on the set value in the normal game state or the small role game.

  FIGS. 8A, 8B, 9, 10A, and 10B are diagrams showing examples of the relationship between the value of the random number for internal lottery and the number of determination values of each combination and the winning combination. . 8 (a), (b) and FIG. 9 show an example of a normal game state, FIG. 10 (a) shows a small role game, and FIG. 10 (b) shows an example of a regular bonus. Yes. FIGS. 8A, 8B, 9, and 10A, 10B show examples where the set value is 6, and FIGS. 8B and 9 are regular. An example in which neither a bonus nor a big bonus winning flag is set is shown.

  In the normal gaming state, the roles that are subject to the internal lottery are regular bonus (1), big bonus (1), big bonus (2), big bonus (3), cherry, watermelon, bell, and replay. In the normal gaming state as described above, the lottery for the small role and the replaying role and the lottery for the special role are performed separately for the same random number for the internal lottery. Random values for internal lottery and the number of judgment values for each role and the winning combination, random values for internal lottery in special lottery and the relationship between the number of judgment values for each role and the winning role, both lotteries The random number value for internal lottery and the relationship between the number of determination values for each combination and the winning combination will be described.

  For example, as shown in FIG. 8 (a), the winning roles in the lottery of the small role and the replaying role in the normal gaming state are cherry, watermelon, bell, and replay. The number of values is 269, 68, 3582, 2245. When the cherry that is the target of the lottery of the small combination and the re-playing combination is added as the random number for internal lottery 16115-16383, the addition result overflows by adding 31 judgment values Will be won.

  Next, the watermelon that is the target of the lottery of the small combination and the re-playing combination adds 337 that is the sum of the determination value number 269 of cherry and the determination value 68 of watermelon, and the addition result overflows 16047 When ˜16114 is acquired as a random number for internal lottery, it is won. Similarly, when 12465 to 16046 are acquired as random numbers for internal lottery, the replay is determined to be winning when 10220 to 12464 are acquired as random numbers for internal lottery.

  The approximate winning probabilities of the small role and the replaying role calculated based on the number of judgment values are 1 / 60.9, 1 / 240.9, 1/4 for cherry, watermelon, bell, and replay, respectively. .6, 1 / 7.3. In addition, when 0-10219 is acquired as a random number for internal lottery, all the small combinations and re-playing combinations are lost.

  On the other hand, as shown in FIG. 8 (b), in the lottery of special roles in the normal gaming state, the target roles are big bonus (1) -A, big bonus (2) -A, big bonus (3) -A. , Loss-A, Big Bonus (1) -B, Big Bonus (2) -B, Big Bonus (3) -B, Loss-B, Big Bonus (1) -C, Big Bonus (2) -C, Big Bonus (3) -C, regular bonus (1). At the set value 6, the number of determination values is 2, 2, 2, 263, 4, 4, 4, 5883, 14, 14, 14, 31, 16382 to 16383, 16380 to 16381, 16378 to 16379, 16115 to 16674, 16111 to 16114, 16107 to 16110, 16103 to 16106, 10 When the 20～16102,10206～10219,10192～10205,10178～10191,10147～10777 has been acquired as a random number for the internal lottery, it is determined to win (loss of the special role). In addition, the approximate winning probabilities of the respective roles are 1/8192, 1/8192, 1/8192, 1 / 62.3, 1/4096, 1/4096, 1/4096, 1 / 2.8, 1 / 1170.3, 1 / 11170.3, 1 / 11170.3, 1 / 528.5. When 0-10146 is acquired as a random number for internal lottery, all special roles are lost.

  Then, a random number range (16115 to 16383) for internal lottery in which cherries are determined to be won in the lottery of the small role and replaying role, and big bonus (1) -A, big bonus (2)- A, Big Bonus (3)-A range of random numbers for internal lottery (16382-16383, 16380-16381, 16378-16379) in which A is determined to be winning overlap, so the values in these overlapping ranges are for internal lottery Are obtained as the random numbers, it is determined that the big bonus (1) and cherry, the big bonus (2) and cherry, and the big bonus (3) and cherry are won simultaneously. Similarly, a random number range (16047 to 16114) for internal lottery in which watermelons are determined to be winning in the lottery of the small role and replaying role, and big bonus (1) -B and big bonus (2) in the lottery of special role -B, Big Bonus (3)-Since the range of random numbers for internal lottery (16111 to 16114, 16107 to 16110, 16103 to 16106) in which B is determined to be winning overlap, the values of these overlapping ranges are When obtained as random numbers for internal lottery, it is determined that the big bonus (1) and watermelon, the big bonus (2) and watermelon, and the big bonus (3) and watermelon are won at the same time.

  Therefore, in the normal gaming state, as shown in FIG. 9, when 16382-16383, 16380-16381, 16378-16379 are obtained as random numbers for internal lottery, big bonus (1), cherry, big bonus, respectively (2) and cherry, big bonus (3) and cherry are determined to be won at the same time, and when 16115 to 16377 are acquired as random numbers for internal lottery, it is determined that only cherry is won alone, When 16114, 16107-16110, and 16103-16106 were acquired as random numbers for internal lottery, big bonus (1) and watermelon, big bonus (2) and watermelon, and big bonus (3) and watermelon were won simultaneously. It is determined that 16047-16102 is a random for internal lottery It is determined that only the watermelon has been won alone, and when 12465-16046 is acquired as a random number for internal lottery, it is determined that only the bell has been won alone, and 10220-12464 is internal. When it was acquired as a random number for lottery, it was determined that only replay was won alone, and when 10206-10219 was acquired as a random number for internal lottery, only the big bonus (1) was won alone When it is determined that 10192 to 10205 are acquired as random numbers for internal lottery, it is determined that only the big bonus (2) is won alone, and when 10178 to 10191 is acquired as random numbers for internal lottery, Only the big bonus (3) is determined to be won alone, and 10147 to 10177 are acquired as random numbers for internal lottery When it is, and only the regular bonus (1) is determined to have elected alone.

  And the approximate probability of winning both Big Bonus (1) and Cherry, Big Bonus (2) and Cherry, Big Bonus (3) and Cherry is 1/8192, respectively. 62.3, and the approximate probability that the big bonus (1) and watermelon, the big bonus (2) and watermelon, and the big bonus (3) and watermelon will be won at the same time is 1/4096, respectively. The probability is 1 / 292.6, and the approximate probability that the bell, replay, big bonus (1), big bonus (2), big bonus (3), regular bonus (1) will be won independently is 1/4. 6, 1 / 7.3, 1 / 11170.3, 1 / 11170.3, 1 / 11170.3, 1 / 528.5 . When 0-10146 is acquired as a random number for internal lottery, all combinations are lost.

  As described above, in this embodiment, the number of judgment values stored in the address area registered in the role-specific table for the small role and the re-playing role and the address value registered in the role-specific table for the special role are stored. From the determined number of judgment values, it is possible to specify the range of judgment values that each of the small role, replaying role, and special role wins independently, and the range of judgment values that the small role and special role will win In the internal lottery, the value obtained as a random number for internal lottery is included in the range of judgment values that each of the small role, replaying role, and special role specified by the number of judgment values wins independently. If it is determined that the small role, the replaying role, and the special role are each elected alone, and if the small role and the special role are included in the range of determination values to be won, the small role and the special role Both of them are judged to have won.

  Further, in this embodiment, the determination value for the big bonuses (1) to (3) and the watermelon to be won more than the determination value range for the big bonuses (1) to (3) and the cherry to be won. The probability of winning the big bonuses (1) to (3) and watermelon at the same time is higher than the probability of winning the big bonuses (1) to (3) and cherry at the same time. Is higher.

  In the normal gaming state, when either the regular bonus or the big bonus winning flag is already set, that is, when these winning flags are set in the previous game and carried over, Since only lottery of re-playing roles is performed, the random number value that determines each winning combination and the winning probability of each winning combination are as shown in FIG.

  In addition, as shown in FIG. 10A, in the small role game, cherry, watermelon, bell, regular bonus (2), and JACIN are subject to internal lottery, and the number of determination values is 269, 68, 3582, 32, 4311. Therefore, when 16115-16383, 16047-16114, 12465-16046, 12433-12464, and 8122-12432 are acquired as random numbers for internal lottery, it is determined that the winner is won. In addition, the approximate winning probabilities of the respective combinations are 1 / 60.9, 1 / 240.9, 1 / 4.6, 1/512, and 1 / 3.8. When 0 to 8121 are acquired as random numbers for internal lottery, all combinations are lost.

  Also, as shown in FIG. 10B, in the regular bonus, JAC, cherry, watermelon, and bell are subject to internal lottery, and the number of determination values is 27, 269, 68, 15919. When 16383, 16088 to 16356, 16020 to 16087, and 101 to 16019 are acquired as random numbers for internal lottery, it is determined that the winner is won. In addition, the approximate winning probabilities of each combination are 1 / 606.8, 1 / 60.9, 1 / 240.9, and 1 / 1.03. When 0 to 100 are acquired as random numbers for internal lottery, all combinations are lost.

  Next, acquisition of random numbers for internal lottery will be described in detail with reference to FIG. The random numbers for the internal lottery are obtained by extracting random numbers from the random number generation circuit 42 by the hardware random number function and processing them by software by the CPU 41a. Note that the least significant bit of the random number extracted from the random number generation circuit 42 or the processed random number is called the 0th bit, and the most significant bit is called the 15th bit.

  FIG. 11A is a block diagram showing the configuration of the random number generation circuit 42 in detail. As shown in the figure, the random number generation circuit 42 includes a pulse generation circuit 42a, a lower counter 42b, and an upper counter 42c. The lower counter 42b and the upper counter 42c are both 8-bit (1 byte) counters, the lower counter 42b is the 0th to 7th bits, and the upper counter 42c is a total of 16 bits from the 8th to 15th bits. The data signal is output.

  The pulse generation circuit 42a outputs a pulse signal at a frequency that is higher than the frequency of the operation clock of the CPU 41a and is not an integral multiple thereof (preferably relatively prime). The pulse signal output from the pulse generation circuit 42a is clocked into the lower counter 42b.

  The lower counter 42b alternately inverts the 0th bit data signal between the H level and the L level every time a pulse signal is input from the pulse generation circuit 42a. Assuming that positive logic is applied, a logical value of H level corresponds to 1 and a logical value of L level corresponds to 0. In the case of negative logic, a logic value of 1 may be read as L level, and a logic value of 0 may be read as H level. When the level of the 0th bit data signal is inverted from H level to L level, that is, whenever the logic value of the 0th bit data signal changes from 1 to 0, the level of the 1st bit data signal is changed to H level. Inverted alternately with L level.

  Similarly, when the level of the (m−1) th bit data signal is inverted from the H level to the L level, that is, whenever the logic value of the (m−1) th bit data signal changes from 1 to 0, the mth bit data The signal level is alternately inverted between the H level and the L level. The carry signal is output every time the level of the seventh bit data signal changes from H level, that is, the logical value of the seventh bit data signal changes from 1 to 0. The carry signal output from the lower counter 42b is clocked into the upper counter 42c.

  The upper counter 42c alternately inverts the eighth bit data signal between the H level and the L level every time a carry signal is input from the lower counter 42b. Each time the level of the 9th bit data signal is inverted from H level to L level, the level of the 9th bit data signal is alternately inverted between H level and L level. Similarly, every time the level of the m−1th bit data signal is inverted from the H level to the L level, the level of the mth bit data signal is alternately inverted between the H level and the L level.

  The logic value of a 16-bit data signal in which the data signal of the lower counter 42b is the lower 8 bits and the data signal of the upper counter 42c is the upper 8 bits is 0 (0000h) every time the pulse generation circuit 42a outputs the pulse signal. ) → 1 (0001h) → 2 (0002h) →... → 65535 (FFFFh) The values are updated so as to be continuous every update, and the maximum value 65535 (FFFFh) is next to the initial value 0 (0000h). The value circulates and is output from the random number generation circuit 42.

  The sampling circuit 43 includes a latch circuit, and latches and latches a 16-bit data signal output from the random number generation circuit 42 at that time based on a sampling command (when the start switch 7 is operated) from the CPU 41a. Output the data signal. The CPU 41a extracts numerical data corresponding to the data signal input from the sampling circuit 43 via the I / O port 41d as a random number generated by the random number generation circuit. In the following description, the data signal output from the random number generation circuit 42 is described as a random number corresponding to the logical value.

  FIG. 11B is an explanatory diagram until the CPU 41a processes the random number extracted from the random number generation circuit 42 into a random number for internal lottery by software. The random number extracted from the random number generation circuit 42 is stored in a 16-bit general-purpose register 41GR included in the CPU 41a.

  When the random number extracted from the random number generation circuit 42 is stored in the general-purpose register 41GR, the CPU 41a uses the other general-purpose register or the work area of the RAM 41c to lower-order the bytes of the general-purpose register 41GR (value extracted from the lower-order counter 42b). And the value of the upper byte (the value extracted from the upper counter 42c) are exchanged.

  Next, the CPU 41a performs an OR operation with the value 8080h of the random number in which the upper byte and the lower byte are replaced with respect to the extracted random number. Since the processing work of the CPU 41a is 1 byte, the logical OR operation is actually performed sequentially on the upper byte and the lower byte. By this OR operation, the 15th bit and the 7th bit are always 1. Furthermore, the CPU 41a shifts the upper 1 byte (8th bit to 15th bit) to the lower bit by bit, and inserts 1 into the empty 15th bit.

  The CPU 41a acquires the value stored in the general-purpose register 41GR at this time as a random number for internal lottery, stores it in a predetermined area of the RAM 41c, and sequentially adds the number of determination values of each combination to this It becomes. Since the 15th and 14th bits of the random number for internal lottery are always 1, the random number for internal lottery is a random number having a size of 14 bits (16384), which is substantially 0 to 16383. It takes a value.

  Note that interrupts to the CPU 41a are prohibited from the extraction of random numbers from the random number generation circuit 42 to the end of processing. This is to prevent the contents of the general-purpose register 41GR from being rewritten in the interrupt processing routine when an interrupt is generated to the CPU 41a.

  Next, the arrangement of symbols on the reels 2L, 2C, and 2R and stop control will be described. As described above, the rotation of the reels 2L, 2C, and 2R is stopped within a drawing range within 4 symbols from when the stop switches 8L, 8C, and 8R are operated. The symbol to be stopped is selected according to the setting status of the winning flag, and the symbols of the winning combination in the drawing range of 4 symbols are aligned and stopped on the effective line set in each game. If you can, stop them all together. Symbols that have not been selected will be stopped in the range of 4 symbols.

  Here, as shown in FIG. 2, “watermelon”, “bell”, and “JAC” are arranged at intervals of 5 symbols or less on all of the reels 2L, 2C, and 2R, and the drawing range of 4 symbols Thus, the variable display device 2 can always be stopped at any position. In other words, when the winning flags of watermelon, bell, replay, JAC, and JACIN are set, the winning combination can always be won regardless of the operation timing of the stop switches 8L, 8C, and 8R by the player.

  Next, the setting of the bet amount and the settlement of credits (including medals used for setting the bet number) will be described. 12 to 16 are timing charts showing a period during which the setting of the bet amount is allowed and a period during which the credit settlement is allowed.

  As shown in FIG. 12, while the game is not being executed, the setting of the bet number and the settlement of the credit are permitted. In this state, the bet number is set by inserting a medal or using the credit. Settings are controlled to be possible. If a bet number can be set and a prescribed number of bets according to the gaming state is not set, the bet number is incremented by one each time a medal is detected. Further, if a prescribed number of bets corresponding to the gaming state is set, a credit is added by one each time a medal is detected. When the credit reaches the upper limit (50 in this embodiment), the flow path switching solenoid 30 is turned off, the flow path of the inserted medal is switched to the medal payout exit 9 side, and the insertion of the medal is prohibited. . If the credit remains, the number of bets is set according to these switches by operating the 1BET switch 5 or the MAXBET switch 6, and the amount is subtracted from the credit. Further, if the credits remain or the bet number is set, the operation of the settlement switch 10 is used to set the medal and the bet amount stored as credits by driving the hopper motor 34. The given amount of medals is paid out and returned to the player, and credits and bets are subtracted according to the medals paid out.

  When the start switch 7 is operated in a state where the setting of the bet amount and the credit settlement are permitted, and the game is started, the setting of the bet amount and the credit settlement are prohibited at that time. Specifically, the flow path switching solenoid 30 is turned off, the flow path of the inserted medal is switched to the medal payout exit 9 side, and the operations of the 1BET switch 5, the MAXBET switch 6, and the settlement switch 10 are invalidated. The time when the game is started is not the time when the rotation of the reel is started, but the time when the control stage is shifted by operating the start switch 7. This is because although a certain period of time has not elapsed since the start of the previous game, there is a case where a weight is applied. At this point, the game starts as a control stage although the reel rotation is on standby.

  Thereafter, the rotation of the reels 2L, 2C, and 2R is stopped, and the display result is derived for all the reels 2L, 2C, and 2R. When the display result is derived, it is determined that the game has ended, and when the end of the game is determined, the setting of the bet amount and the prohibition of credit settlement are lifted, and the setting of the bet amount and credit settlement are permitted. It becomes a state. As an exception, when a replay win occurs, the bet number is automatically set, so the setting of the bet number by the player's operation remains prohibited. In this state, Credit settlement is also prohibited.

  As a result of stopping the rotation of the reels 2L, 2C, and 2R, if a winning with a medal payout has occurred, display results are derived for all the reels 2L, 2C, and 2R as shown in FIG. At the time, the end of the game is not determined, and when the medal payout accompanying the occurrence of the winning is completed, the end of the game is determined, and at that time, the setting of the bet amount and the prohibition of the credit settlement are canceled, and the bet Number setting and credit settlement are permitted.

  Further, if the big bonus winning is generated as a result of the rotation of the reels 2L, 2C, 2R being stopped, as shown in FIG. 14, when the display results are derived for all the reels 2L, 2C, 2R, However, the setting of the number of bets is prohibited from the time when the end of the game is determined until the BB winning stage effect waiting time, which will be described later, is executed. In this state, at the time when the production waiting time for the BB winning effect has passed, the setting of the betting amount is canceled and the setting of the betting amount is permitted. On the other hand, with regard to credit settlement, the prohibition is lifted when the end of the game is determined, and credit settlement is permitted from that point.

  In addition, in the game during the big bonus, as a result of the rotation of the reels 2L, 2C, 2R being stopped, the game where the big bonus end condition is satisfied, that is, some winning occurs and the total number of payouts in the big bonus reaches 465 If the game is a stop game and the stop function is not set, as shown in FIG. 15, the end of the game is determined at the end of the medal payout, but the end of the game is determined. Until the ending stage production waiting time, which is the period in which the ending stage to be described later, elapses, the setting of the number of bets remains prohibited, and when the ending stage production waiting time elapses, The prohibition on the setting of the betting number is released, and the setting of the betting number is permitted. On the other hand, with regard to credit settlement, the prohibition is lifted when the end of the game is determined, and credit settlement is permitted from that point.

  On the other hand, if the stop function is set, as shown in FIG. 16, the end of the game is determined when the medal payout is ended, but the end of the game is determined, and the effect of the ending effect is determined. Since the stop state is controlled when the waiting time elapses, the setting of the betting number remains prohibited until the reset switch 23 or the reset / setting switch 38 is operated even when the production waiting time of the ending effect elapses. In this state, when the reset switch 23 or the reset / setting switch 38 is operated and the stop state is released, the setting of the betting number is also released, and the setting of the betting number is permitted. On the other hand, with regard to credit settlement, the prohibition is lifted when the end of the game is determined, and credit settlement is permitted from that point.

  In this embodiment, the end condition of the big bonus is that the total number of payouts in the big bonus reaches 465. Therefore, in a game in which the end condition of the big bonus is satisfied, the medal is always paid out. When the payout ends, the end of the game is determined. For example, when applying that the big bonus reaches the specified number of games as an end condition, the game in which the end condition of the big bonus is satisfied In this case, the end of the game is determined when the display results of all the reels 2L, 2C, and 2R are derived.

  Next, error control associated with medal payout will be described. The CPU 41a performs control for driving out the hopper motor 34 and paying out medals in accordance with the occurrence of the small role winning and the settlement of credits (including medals used for setting the bet amount). At this time, if medals are continuously detected by the payout sensor 35 for a predetermined time or more, it is determined that the medals are clogged, the driving of the hopper motor 34 is stopped, and the progress of the game is stopped by controlling to an error state. If no medal is detected by the payout sensor 35 for a certain period of time despite the hopper motor 34 being driven, the hopper motor 34 is stopped once and the hopper motor 34 is restarted several times. If no medal is detected by the payout sensor 35 even after the trial, it is determined as a hopper error (an error indicating a lack of medals in the hopper), and the progress of the game is stopped by controlling to an error state. The error states associated with these medal jamming errors and hopper errors are canceled by operating the reset switch 23 and the reset / setting switch 38, and control for paying out the remaining medals is performed.

  Next, initialization of the RAM 41c of the main control unit 41 will be described. The RAM 41c of the main control unit 41 has a storage area of 512 bytes. As shown in FIG. 17, addresses of 7E00 (H) to 7FFF (H) are assigned to each byte, as well as important work. , General work, special work, set value work, unsaved work, unused area, stack area.

  The important work is an area of 40 bytes from 7E00 (H) to 7E27 (H), and it is a big bonus such as various display and LED display data, I / O port 41d input / output data, game time counter, etc. This work stores data that is inconvenient if it is initialized at the end.

  The general work is a 178-byte area of 7E28 (H) to 7E8E (H), 7EBA (H) to 7F04 (H), stop symbol data, number of medals to be paid out, winning combination flag, medal in big bonus This work stores data that can be initialized at the end of the big bonus, such as the total number of payouts.

  The special work is a 39-byte area from 7E8F (H) to 7EB5 (H), and data for transmitting commands to the effect control board 90, various software random numbers, etc., are initialized only before the start of setting. The work to be stored.

  The set value work is a 1-byte area of 7EB6 (H) and is a work in which the set value is stored. After 0 is stored in the initialization before the setting is started (before the transition to the setting change mode), It is corrected to 1, and the set value newly set at the end of the setting (at the end of the setting change mode) is stored.

  The unsaved work is a 3-byte area of 7EB7 (H) to 7EB9 (H), and is a work that holds the state of various switches as the state of the stop switch 36. The data in the RAM 41c is destroyed at the time of startup. A value is always set regardless of whether it is present or not.

  The unused area is a 205-byte area from 7F05 (H) to 7FD1 (H) and is an unused area in the storage area of the RAM 41c, and any one of a plurality of initialization conditions to be described later is satisfied. Then it will be initialized.

  The stack area is a 45-byte area from 7FD2 (H) to 7FFF (H), and the area from 7FD2 (H) to stack pointer-1 is an unused stack area in the stack area. The area of the stack pointer to 7FFF (H) is an in-use stack area in which data saved from the register of the CPU 41a is stored. Of these, the unused stack area is initialized if any one of a plurality of initialization conditions to be described later is satisfied, as in the case of the unused area. Therefore, it is not initialized.

  In the present embodiment, as shown in FIG. 18A, the CPU 41a of the main control unit 41 does not destroy the data in the RAM 41c before starting the setting (before shifting to the setting change mode), at the end of the big bonus, or at the time of activation. At the time, when four initialization conditions at the end of one game are satisfied, four types of initializations with different areas initialized according to each initialization condition are performed.

  Initialization 1 is an initialization that is performed before the setting key switch 37 is turned on at the time of startup and shifts to the setting change mode. In the initialization 1, the use of the storage area of the RAM 41c is used. All areas except the middle stack area (including unused areas and unused stack areas) are initialized. Initialization 2 is initialization performed at the end of the big bonus. In initialization 2, the general work, the unused area, and the unused stack area are initialized in the storage area of the RAM 41c. Initialization 3 is initialization that is performed when the setting key switch 37 is in an OFF state at the time of startup and the data in the RAM 41c is not destroyed. The used stack area is initialized. Initialization 4 is initialization performed at the end of one game. In initialization 4, an unused area and an unused stack area in the storage area of the RAM 41c are initialized.

  In the ROM 41b, the start address of the area to be initialized and the initialization size indicating the size of the area to be initialized are registered corresponding to each of initializations 1 to 4, and when the CPU 41a initializes the RAM 41c. Refers to the initialization table, acquires the start address and initialization size corresponding to any of initializations 1 to 4 according to the initialization condition, sets a pointer to the start address, and sets the initialization size . If the initialization size includes the size of the unused stack area, the size of the unused stack area (stack pointer-7FD2 (H)) is calculated and the initialization size is set. Then, the area of the address corresponding to each byte from the initialization address where the pointer is set is cleared to 0, and each time the byte is cleared, the initialization size is decremented by 1 and the pointer is advanced by 1. Run until zero. That is, when the CPU 41a initializes the RAM 41c, it does not initialize each area according to the initialization condition, but initializes an area of a specified size from a specified address.

  FIG. 18B shows an initialization table. In the initialization table, the start address and the initialization size are registered corresponding to the initializations 1 to 4 as described above.

  In initialization 1, 7E00 (H) is registered as the start address, and 1D3 (H) + M (size of unused stack area: (stack pointer−7FD2)) bytes are registered as the initialization size. 7E00 (H) to 1D3 (H) + M bytes are initialized. Then, as shown in FIG. 17, important work, general work, special work, set value work, unsaved work, general work, unused area, and unused stack area are allocated to address areas that are continuous from 7E00 (H). The sum of the sizes of these areas is 1D3 (H) + M bytes. Therefore, in initialization 1, 7D00 (H) is initialized to 1D3 (H) + M bytes, so that These areas are initialized in the order of general work, special work, set value work, non-saved work, general work, unused area, and unused stack area.

  In initialization 2, two start addresses and initialization sizes for each address are registered. This is because the general work initialized in the initialization 2 is allocated to two separate address areas. In initialization 2, 7E28 (H) is registered as the start address of the area to be initialized first, 67 (H) bytes are registered as the initialization size, and 7EB7 (H) is set as the start address of the area to be initialized next. Since 118 (H) + M bytes are registered as the conversion size, in initialization 2, an area for 7E28 (H) to 67 (H) bytes and an area for 7EB7 (H) to 118 (H) + M bytes Is initialized. The size of the general workpieces 7E28 (H) to 7E8E (H) is 67 (H) bytes. As shown in FIG. 17, the remaining general workpiece area, unused area, and unused stack area are 7EB7 ( H) are allocated to consecutive address areas, and the total size of these areas is 118 (H) + M bytes. Therefore, in initialization 2, 7E28 (H) to 67 (H) bytes are initialized, By initializing 7EB7 (H) to 118 (H) + M bytes, these areas are initialized in the order of general work, unused area, and unused stack area.

  Also in the initialization 3, two start addresses and initialization sizes for each address are registered. This is because the non-saved work initialized in the initialization 3 and the unused area and the unused stack area are allocated to two separate address areas. In initialization 3, 7EB7 (H) is registered as the start address of the area to be initialized first, 3 (H) bytes are registered as the initialization size, and 7F05 (H) is set as the start address of the area to be initialized next. Since CD (H) + M bytes are respectively registered as the conversion size, in initialization 3, an area from 7EB7 (H) to 3 (H) bytes and an area from 7F05 (H) to CD (H) + M bytes Is initialized. As shown in FIG. 17, the unsaved work is an area for 3 bytes from 7EB7 (H), and the unused area and the unused stack area are allocated to address areas that are continuous from 7F05 (H). Since the total size of these areas is CD (H) + M bytes, in initialization 3, 7EB7 (H) to 3 (H) bytes are initialized, and 7F05 (H) to CD (H) + M bytes. When the minutes are initialized, these areas are initialized in the order of the non-saved work, the unused area, and the unused stack area.

  In initialization 4, 7F05 (H) is registered as the start address and CD (H) + M bytes are registered as the initialization size. Therefore, in initialization 4, an area from 7F05 (H) to CD (H) + M bytes is registered. Is initialized. As shown in FIG. 17, the unused area and the unused stack area are allocated to address areas that continue from 7F05 (H), and the total size of these areas is CD (H) + M bytes. Therefore, in initialization 4, the CD (H) + M bytes from 7F05 (H) are initialized, so that these areas are initialized in the order of the unused area and the unused stack area. .

  In addition, initializations 1 and 3 among initializations 1 to 4 are processes performed after the CPU 41a is started and before an interrupt is permitted. On the other hand, the initializations 2 and 4 are processes performed in a state where interrupts are permitted, but interrupts are prohibited during the execution of these initializations 2 and 4. That is, interrupts are always prohibited during the initializations 1-4.

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

  FIG. 19 is a diagram illustrating an example of a command transmitted from the main control unit 41 to the effect control board 90.

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

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

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

  The reel stop command is a command that can specify whether the reel to be stopped is the left reel, the middle reel, or the right reel, or the symbol to stop on the corresponding reel, and every time the reel is controlled to stop. Sent.

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

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

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

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

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

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

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

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

  Of these commands, commands other than the initialization command are generated in a startup process and a game process described later, temporarily stored in a command queue provided in a special work in the RAM 41c, and transmitted in the timer interrupt process described above. When an error command indicating a RAM abnormality error is transmitted when the main control unit 41 is activated, it is transmitted in the activation process, not the timer interruption process. This is because, as will be described later, interrupts are prohibited when a RAM abnormality error occurs when the main control unit 41 is activated.

  FIG. 20 is a diagram showing the configuration of the command queue described above. The command queue is provided with an area capable of storing a maximum of 16 commands so that a plurality of commands can be accumulated. In addition, in the area for storing each command, a numerical value (0 to 15) indicating an area number is set in association with each storage area. Further, a transmission pointer indicating the area number of the area where the command to be transmitted next is stored and a storage pointer indicating the area number of the area where the command is to be stored next are set in the command queue. The transmission pointer is incremented by 1 every time an unsent command stored in the command queue is transmitted, and the storage pointer is incremented by 1 when storing the command. The area number indicated by the transmission pointer and the area number of the storage pointer are the same number when transmitted and when all areas of the command queue are full due to an untransmitted command. If an unsent command is stored, the unsent flag is set. Therefore, if the area number indicated by the send pointer is the same as the area number of the stored pointer, the unsent flag is set. If it is, the command queue is shown to be full of unsent commands, and if the unsent flag is not set, it is shown that the unsent commands are empty.

  In this embodiment, the CPU 41a generates an interrupt 3 at an interval of 0.56 ms, and executes a timer interrupt process when the interrupt 3 occurs, so that the timer interrupt process is executed every 0.56 ms. It becomes. Further, as shown in FIG. 21, in timer interrupt processing, timer interrupts 1 to 4 are repeatedly performed, and processing unique to these timer interrupts 1 to 4 is performed at intervals of 2.24 ms. Will be. Since the command transmission process for transmitting the command stored in the command queue is executed by the timer interrupt 2, the command transmission process is also executed at an interval of 2.24 ms.

  On the other hand, as will be described later, the sub control unit 91 acquires the buffered command in the timer interrupt process (sub) in which the command is executed at intervals of 1.12 ms. For this reason, every time the CPU 41a executes a timer interrupt process, that is, when a command transmission process is performed at an interval of 0.56 ms, there is a possibility that the sub-control unit 91 cannot receive the command normally.

  However, in this embodiment, as described above, the CPU 41a executes the command transmission process at a rate of once every four timer interruption processes, that is, at an interval of 2.24 ms, so that two commands are transmitted continuously. Even in such a case, the commands are transmitted at intervals of at least 2.24 ms, and the commands transmitted continuously can be reliably acquired on the sub-control unit 91 side.

  FIGS. 22A and 22B are timing charts showing an example of command transmission status in this embodiment.

  In this embodiment, as shown in FIG. 22A, a command is generated according to the progress of the game and stored in the command queue. When an unsent command stored in the command queue is detected in the command transmission process in timer interrupt 2, a delay time is set, and when the set delay time elapses, the unsent command stored in the command queue Command is sent.

  Specifically, when an unsent command stored in the command queue is detected in the command transmission process, the random number for delay set in the range of 0 to 15 is acquired, and the acquired value is corrected to 2 to 17 The range value (L) is set in the delay counter provided in the special work of the RAM 41c.

  At this time, in the command transmission process in which the delay counter value (L) is set and the command transmission process executed in the timer interrupt 2 thereafter, the delay counter value is decremented by 1, and the delay counter value becomes 0. At that time, the command stored in the command queue is transmitted.

  That is, the command detected in the command transmission process is a time corresponding to a multiple of the command transmission process execution interval (2.24 ms), more specifically, a value obtained by subtracting 1 from the delay counter value (L) acquired at that time ( (L-1) multiplied by the execution interval (2.24 ms) of command transmission processing {(L is a value of 2 to 17, so 2.24 to 35.84 ms} has passed, and then the transmission is performed. .

  Also, in this embodiment, an area capable of storing a plurality of commands is provided in the command queue, and a newly generated command is set in an empty area of the command queue without waiting for transmission of the command stored in the command queue. It is possible to store. That is, a plurality of commands can be accumulated. For this reason, it can be avoided that the progress of the game is stopped due to the delay of the command transmission. Note that this is not the case when the command queue is full of unsent commands.

  In the command storage process, when a plurality of commands are stored in the command queue, these commands are stored in the order of generation, and in the command transmission process, the commands are transmitted in the order stored in the command queue. That is, commands stored in the command queue are always transmitted in the order in which they are generated.

  In addition, when a plurality of unsent commands are stored in the command queue, after the first generated command is transmitted, the unsent commands are stored in the command queue again in the command transmission process to be executed next. If the command is stored, the delay time (delay counter value) of the command is set at that time, and the command is transmitted when the delay time has elapsed. Therefore, when a plurality of commands are stored in the command queue, even if each transmission interval is the shortest (when 2 is determined as the delay counter value), as shown in FIG. .48 ms (2.24 × 2 ms) are transmitted at intervals. In other words, transmission of a new command is prohibited until 4.48 ms elapses after the command is transmitted.

  In the slot machine 1 of the present embodiment, the number of symbols arranged on the reels 2L, 2C, and 2R is 21, and the rotation speed is 750 ms and the rotation is 1 rotation (80 rotations per minute). The time required for each reel 2L, 2C, 2R to move one symbol is 35.7 ms (= 750/21 ms).

  Further, in order to prevent an effect that assists the presentation on the effect control board 90 side, when the CPU 41a transmits a command to the effect control board 90, the maximum delay time is set. It is necessary to set a time longer than the time required for the reels 2L, 2C, and 2R to move one symbol. That is, in this embodiment, it is necessary to set a time of 35.7 ms or more as the maximum delay time.

  On the other hand, in order to prevent a sense of discomfort caused by a large gap between the effect by the sub-control unit 91 mounted on the effect control board 90 and the control by the main control unit 41, the maximum delay time in the command transmission process It is preferable to make the value as short as possible. That is, in the case of the present embodiment, it is preferable that the maximum value of the delay time is set to 35.7 ms or more and as close as possible to 35.7 ms. In the present embodiment, as described above, the delay time in the command transmission process can be set only for a time corresponding to a multiple of the execution interval (2.24 ms) of the command transmission process. Since the minimum value among the values of 35.7 ms or more is 2.24 ms × 16 = 35.84 ms, the optimum maximum delay time is 35.84 ms in the slot machine 1 of the present embodiment.

  For this reason, it is only necessary to set 17 as the upper limit value of the delay counter value (L), and in this way, the maximum value of the delay time is prevented in order to prevent the effect of assisting in the present embodiment. It is possible to set the minimum value among the values that are equal to or greater than the maximum value of the minimum delay time required.

  Further, in this embodiment, as shown in FIG. 22B, a power failure occurs before the delay time {2.24 × (La-1) ms} set when an untransmitted command is detected. When a power interruption interrupt process described later is executed, the command stored in the command queue, the transmission pointer, the value of the stored pointer, the untransmitted flag, and the delay at that point The counter value La ′ is backed up. If untransmitted commands remain after the interruption of power is restored and the interrupt prohibition is canceled, the delay counter value La ′ set at that time becomes zero. Send a send command. That is, at the time of restoration of power interruption, subtraction is resumed from the value La ′ of the delay counter at the time of power interruption, and the delay time {2.24 × (La′−1) ms} has elapsed after the restoration of power interruption. By doing so, an unsent command is sent.

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

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

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

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

  Further, the CPU 91a refers to a control pattern for executing a special BB winning effect at the time of winning a big bonus when receiving a winning determination command indicating that a big bonus winning has occurred, based on the control pattern. Control the production. As a result, as shown in FIG. 14, the BB winning effect, in which the fanfare is output or the like, is executed over the period until the prohibition of the setting of the betting number is canceled (the waiting time for the BB winning effect). It will be.

  Further, when the CPU 91a receives a game state command indicating the end of the game in which the big bonus end condition is satisfied, the CPU 91a refers to the control pattern for executing the ending effect indicating the end of the big bonus, Based on this, the production is controlled. As a result, as shown in FIG. 15, the ending effect in which the end screen is displayed or the like is executed over the period until the prohibition of the bet number setting is canceled.

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

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

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

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

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

  If the RAM parity is 0 in step Sa8, it is further determined whether or not the destructive diagnosis data is normal (Sa9). If power interruption interrupt processing is performed normally, the data for destruction diagnosis should be set. If the data for destruction diagnosis is not normal in step Sa9 (the data for destruction diagnosis is stored at the time of power interruption. Since the data in the RAM 41c is not normal, the error code indicating the RAM abnormality is set in the RAM 41c (Sa10), and the process proceeds to the error processing shown in FIG.

  In the error processing, as shown in FIG. 24, the current display state of the game auxiliary display 12 is saved in the stack (Sb1), and the error code set in the RAM 41c is displayed on the game auxiliary display 12 (Sb2). .

  Next, the error code set in the RAM 41c is confirmed, it is determined whether or not the error code is an error code indicating a RAM abnormal error (Sb3), and an error code indicating an error code indicating a RAM abnormal error is set. If it is determined that the error code is an error code indicating a RAM abnormality error, the process proceeds to a loop process in which no process is performed.

  If an error code indicating a non-RAM error is set in step Sb3, it is determined whether an operation of the reset / setting switch 38 is detected (Sb4). If the operation is not detected, it is further determined whether or not the operation of the reset switch 23 is detected (Sb5). If the operation of the reset switch 23 is not detected, the process returns to the step Sb4. That is, the game waits in a state where the progress of the game is impossible until the operation of the reset / setting switch 38 or the reset switch 23 is detected.

  If the operation of the reset / setting switch 38 is detected in the step Sb4 or the operation of the reset switch 23 is detected in the step Sb5, the error code set in the RAM 41c is cleared (Sb6 ), The display state of the game auxiliary display 12 is returned to the display state saved in the stack in step Sb1 (Sb7), and the process returns to the original process.

  As described above, in the error processing, if the error processing is other than the RAM abnormality error, the reset / setting switch 38 or the reset switch 23 is operated to return to the original processing even if the error state is canceled. In the case of error processing due to a RAM abnormality error, the error state is not canceled even if the reset / setting switch 38 or the reset switch 23 is operated.

  Returning to FIG. 23, when it is determined in the step Sa9 that the data for failure diagnosis is normal, the data in the RAM 41c is normal, so the unsaved work, the unused area, and the unused stack area in the RAM 41c are initialized. After performing initialization 3 (Sa11), the destruction diagnosis data is cleared (Sa12). Next, each register is restored to the state before the power interruption, that is, the state saved in the stack (Sa13), the interrupt is permitted (Sa14), and the process that was executed last before the power interruption is returned.

  If the setting key switch 37 is in the ON state in the step of Sa6, after executing initialization 1 for initializing all storage areas in the storage area of the RAM 41c except the used stack area (Sa15), The value (0 at this time) stored in the set value work is corrected to 1 (Sa16). Next, interruption is permitted (Sa17), and the setting change process shown in FIG. 25, that is, the setting change mode is entered (Sa18). After the setting change process is completed, the process proceeds to the game process.

  In the setting change process, as shown in FIG. 25, since the setting value stored in the setting value work of the RAM 41c (the value of the setting value work is corrected to 1 before shifting to the setting changing process, 1 is set here). Is read out (Sc1).

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

  When the operation of the start switch 7 is detected in the step of Sc3, the changed set value selected at that time is stored in the set value work of the RAM 41c and the set value is confirmed (Sc7). Wait until the setting key switch 37 is turned off (Sc8). If it is determined in step Sc8 that the setting key switch 37 is OFF, the process returns to the flowchart of FIG. 23 and the process proceeds to the game process.

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

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

  FIG. 26 is a flowchart showing the control contents of the game process executed by the CPU 41a.

  In the game process, a BET process (Sd1), an internal lottery process (Sd2), a reel rotation process (Sd3), a reel stop process (Sd4), a winning determination process (Sd5), a payout process (Sd6), and a game end process (Sd7) ) And freeze processing (Sd8) are executed in order, and when the freeze processing ends, the process returns to the BET processing again.

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

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

  In the reel rotation process in step Sd3, a process of rotating each reel 2L, 2C, 2R is executed. In this reel rotation process, the operation of the stop switches 8L, 8C, 8R is validated when all the reels 2L, 2C, 2R rotate at a constant speed.

  In the reel stop process in the step of Sd4, the player's operation of the stop switches 8L, 8C, 8R is detected, and the corresponding reels 2L, 2C, 2R corresponding to the fact that the stop condition of each reel 2L, 2C, 2R is satisfied. Execute the process to stop the rotation.

  In the winning determination process in step Sd5, when it is determined in step Sd4 that the rotation of all the reels 2L, 2C, and 2R has been stopped, a winning is determined according to the display result derived for each reel 2L, 2C, and 2R. A process of determining whether or not it has occurred is executed.

  In the payout process in step Sd6, when it is determined in step Sd5 that a winning has occurred, processing such as addition of credits and payout of medals is performed based on the number of payouts according to the win.

  In the game end process in the step of Sd7, a process for setting a gaming state in preparation for the next game is executed.

  In the freezing process in the step of Sd8, when the big bonus is won and at the end of the big bonus, a process for delaying the transition to the BET process is performed to disable the setting of the bet number. Also, the stop state at the end of the big bonus is controlled by this process.

  27 and 28 are flowcharts showing the control contents of the BET process executed by the CPU 41a in step Sd1.

  In the BET process, first, the value of the BET counter in which the value of the bet amount is stored in the RAM 41c is cleared (Se1), and it is determined whether or not the game is a replay game (Se2). If a replay game flag indicating that a replay game is in progress is set in the RAM 41c and it is determined that the game is a replay game, the value of the BET counter is incremented by 1, and the bet set in the RAM 41c is set. Specified number of numbers (explained later, this is the specified number of bets determined according to the gaming state, and is set to 1 when in the regular bonus, and 3 when in the normal gaming state and the small role game. However, the process (Se3, Se4) for determining whether or not the value of the BET counter is a specified number is referred to in the step of Se4. The process is repeated until it is determined that the value of the BET counter is the specified number, and it is determined that the value of the BET counter is the specified number in step Se4. Been if waits detection standby state of operation of the start switch 7 (Se5). When the operation of the start switch 7 is detected in this state, the BET process is terminated and the process returns to the flowchart of FIG.

  Further, if the game is not a replay game in the step of Se2, it is determined whether or not the value of the BET counter is a specified number by referring to the specified number of bets set in the RAM 41c (Se6), and the value of the BET counter is specified. If it is a number, it is further determined whether or not the value of the credit counter in which the credit value is stored in the RAM 41c is 50, which is the upper limit value (Se7). If the value of the BET counter is the prescribed number and the value of the credit counter is 50 in the steps of Se6 and Se7, the flow path switching solenoid 30 is turned off, and the medal flow path is set on the medal payout exit 9 side. If a new medal is not allowed to enter the route (Se8) and the BET counter value is not a prescribed number in the Se6 step, or if the credit counter value is not 50 in the Se7 step, the flow path is switched. The solenoid 30 is turned on, and a medal can be inserted using the medal flow path as a path on the hopper tank side (Se9).

  Next, it is determined whether or not both the value of the credit counter and the value of the BET counter are 0 (Se10). If neither the value of the credit counter or the value of the BET counter is 0, the operation of the settlement switch 10 is further performed. (Se11), and if the operation of the checkout switch 10 is detected, the hopper motor 34 is driven to pay out medals for the values stored in the credit counter and the BET counter. That is, after performing the settlement process (Se12) in which the medal stored as credits and the medal used for setting the bet number are returned, the process returns to the step of Se6.

  Further, when both the credit counter value and the BET counter value are 0 in the step of Se10, or when the operation of the settlement switch 10 is not detected in the step of Se12, the inserted medal sensor 31 passes the inserted medal. Is detected (Se13), and if passage of the inserted medal is detected, the prescribed number of bets set in the RAM 41c is referred to and whether or not the value of the BET counter is the prescribed number is determined. If the value of the BET counter is not the specified number (Se14), the value of the BET counter is incremented by 1 (Se15), the process returns to the step of Se6, and if the value of the BET counter is the specified number in the step of Se14 Then, it is determined whether or not the value of the credit counter is 50 (Se16), and if the value of the credit counter is 50, It returns to Se6 step, if the value of the credit counter 50, after 1 is added to the value of the credit counter (SE17), the flow returns to step Se6.

  If the inserted medal is not detected in step Se13, the specified number of bets set in the RAM 41c is referred to determine whether or not the value of the BET counter is the specified number (Se18). If the value of the counter is a specified number, it is determined whether or not the operation of the start switch 7 is detected (Se19). If the operation of the start switch 7 is not detected, the process returns to the step of Se6 as it is. If the operation No. 7 is detected, the flow path switching solenoid 30 is turned off, and the insertion of a new medal is prohibited using the medal flow path as a path on the medal payout exit 9 side (Se20), and the BET process is ended. Then, the process returns to the flowchart of FIG. Accordingly, setting of the betting number based on the detection of the inserted medal sensor 31, the 1 BET switch 5 and the MAXBET switch 6 is prohibited, and the credit settlement based on the detection of the settlement switch 10 is prohibited. In this embodiment, the bet number is set only in the BET process, and the bet number setting is prohibited in the processes of Sd2 to Sd8 shown in FIG. Also, credits (including medals used to set bets) are settled only in the BET process and Sd8 freeze process, which will be described later. Credit settlement is prohibited in the steps from Sd2 to Sd7 shown in FIG. Is done.

  If the value of the BET counter is not a prescribed number in the step of Se18, it is determined whether or not the value of the credit counter is 0 (Se21). If the value of the credit counter is 0, the process returns to the step of Se6. If the value of the credit counter is not 0 in the step of Se21, it is determined whether or not the operation of the single BET switch 5 is detected (Se22). If the operation of the single BET switch 5 is not detected, MAXBET It is determined whether or not the operation of the switch 6 is detected (Se23). If the operation of the MAXBET switch 6 is not detected, the process returns to the step of Se6.

  If the operation of the single BET switch 5 is detected in the Se22 step, the credit counter value is decremented by 1 (Se24), the BET counter value is incremented by 1 (Se25), and the process returns to the Se6 step. . If the operation of the MAXBET switch 6 is detected in the step of Se23, the credit counter value is decremented by 1 until the credit counter value becomes 0 or the BET counter value reaches a specified number, and the BET counter When the value of the credit counter becomes 0 at the step of Se26 or when the value of the BET counter reaches the specified number at the step of Se29, the process of adding 1 to the value of Se6 (Se26 to Se29) is repeated. Return to step.

  FIG. 29 is a flowchart showing the control contents of the settlement process executed by the CPU 41a in the freeze process at the Se12 step and the Sd8 step of the BET process.

  In the checkout process, first, the flow path switching solenoid 30 is turned off, the medal flow path is set as a path on the medal payout exit 9 side, and the insertion of medals is prohibited (Sf1). A single medal payout process is performed (Sf2).

  In the single medal payout process in step Sf2, if the driving state of the hopper motor 34 is not on, the driving state of the hopper motor 34 is set to on. Then, the detection state of the payout sensor 35 is monitored, and when the payout sensor 35 detects the payout of one medal, it is determined that the medal is paid out, and the process proceeds to the next process. Further, when medals are continuously detected by the payout sensor 35 for a predetermined time or more, it is determined that medals are jammed, the driving state of the hopper motor 34 is set to off, and an error code indicating a medal clogging error is set in the RAM 41c. Then, the process proceeds to error processing shown in FIG. If no medal is detected by the payout sensor 35 for a predetermined time or more, the driving state of the hopper motor 34 is once turned off, and no medal is detected by the payout sensor 35 even if the driving of the hopper motor 34 is retried several times. In this case, after an error code indicating a hopper error (an error indicating a lack of medals in the hopper) is set in the RAM 41c, the process proceeds to the error process shown in FIG. The error processing due to the medal jamming error or the hopper error is canceled by operating the reset switch 23 or the reset / setting switch 38, and after the cancellation, the processing returns to the top of the single medal payout processing.

  When one medal is paid out by the medal payout process in step Sf2, it is determined whether or not the value of the BET counter is 0 (Sf3). If the value of the BET counter is not 0, that is, 1 or more bets are made. If the number is set, 1 is subtracted from the value of the BET counter (Sf4), and the process proceeds to step Sf6. On the other hand, if the value of the BET counter is 0 in the step of Sf3, 1 is subtracted from the value of the credit counter (Sf5), and the process proceeds to the step of Sf6.

  In step Sf6, it is determined whether or not the value of the BET counter is 0. If the value of the BET counter is not 0, it is further determined whether or not the value of the credit counter is 0 (Sf7). If neither the value of the BET counter or the value of the credit counter is 0, the process returns to the step of Sf2. That is, every time one medal payout process is performed until the BET counter value and the credit counter value become 0, the process of subtracting the BET counter value and the credit counter value is repeated. At this time, if the values of both the BET counter and the credit counter remain, the BET counter and the credit counter are subtracted in this order.

  If the value of the BET counter and the value of the credit counter are both 0 in the steps Sf6 and Sf7, the driving state of the hopper motor 34 is set to off and the driving is stopped (Sf8). Return to the original process.

  30 to 32 are flowcharts showing the control contents of the internal lottery process executed by the CPU 41a in the step Sd2.

  In the internal lottery process, first, a random number acquisition process whose details will be described later is performed (Sg1). In this random number acquisition process, a random number value for internal lottery is acquired based on a random number generated by a random number generation circuit (not shown).

  Then, the set value stored in the set value work of the RAM 41c is read (Sg2), and whether or not the read set value is in the range of 1 to 6, that is, the set value stored in the set value work is an appropriate value. If the read set value is not a value in the range of 1 to 6, an error code indicating RAM abnormality is set in the RAM 41c (Sg4), and the process proceeds to error processing shown in FIG.

  Further, if the set value read in the step of Sg4 is in the range of 1 to 6, it is determined whether or not the current gaming state is the normal gaming state (Sg5), and if it is the normal gaming state, the normal gaming state Correspondingly, the small combination and re-game combination are read out in the order registered in the winning combination table according to gaming state shown in FIG. 6A (Sg6). The BET number (the number of bets) set in the step of Sd1 is read, and the common flag of the combination corresponding to the small combination and the re-playing combination in FIG. The setting status is acquired (Sg7). As a result, it is determined whether or not a common flag is set for the combination and the BET number (Sg8).

  If the common flag is set, the number of determination values stored at the address registered in the role-specific table for the small combination and replay combination in FIG. 6B is acquired for the combination and the number of BETs. (Sg9). Then, the process proceeds to Sg11. If the common flag is not set, the number of judgment values stored at the address registered in the role-specific table for the small combination and re-playing combination corresponding to the set value read for the combination and the BET number Obtain (Sg10). Then, the process proceeds to Sg11.

  In the step of Sg11, the number of determination values acquired in the step of Sg9 or Sg10 is added to the random number value for internal lottery, and the result of the addition is used as a new random number value for internal lottery. Here, it is determined whether or not an overflow has occurred when the number of determination values is added to the random number for internal lottery (Sg12). If an overflow occurs, the winning flag for the combination is set in the RAM 41c (Sg13). Then, the process proceeds to Sg15 shown in FIG.

  If no overflow has occurred in the step of Sg12, it is determined whether or not there is a combination that has not yet been set as a processing target among the small combination and re-playing combination defined for the normal gaming state (Sg14). If there is a combination that has not yet been processed, the process returns to the processing of Sg6, and the processing continues with the next combination from the small combination and re-playing combination defined for the normal gaming state as the processing target. If there is no combination not to be processed, the process proceeds to Sg15 shown in FIG.

  In step Sg15, it is determined whether a regular bonus or big bonus winning flag has already been set in the RAM 41c in the previous game or not, and it has been carried over without winning based on the winning flag. If the winning flag for the regular bonus or the big bonus has already been set, the internal lottery process is terminated and the process returns to the flowchart of FIG. If neither the regular bonus winning flag nor the big bonus winning flag is set, the random number for internal lottery is returned to the value before the addition, that is, the value acquired in the random number acquisition process of Sg1 (Sg16).

  Next, with reference to the winning combination table according to gaming state shown in FIG. 6 (a) and the special role combination table shown in FIG. 6 (c), lottery of the normal gaming state registered in the winning combination table according to gaming state The target special combination is read out in the order registered in the special combination table for special combination (Sg17). At this time, if the special role lose is registered in the special role-specific table, the special role loses are also read in the registered order. Furthermore, the setting status of the common flag is acquired from the role-specific table for special roles in FIG. 6C (Sg18). As a result, it is determined whether or not a common flag is set for the combination (Sg19).

  If the common flag is set, the number of judgment values stored in the address registered in the special role-specific table of FIG. 6C for the role is acquired (Sg20). Then, the process proceeds to Sg22. If the common flag is not set, the number of determination values stored in the address registered in the special role-specific table corresponding to the set value read for the corresponding role is acquired (Sg21). Then, the process proceeds to Sg22.

  In the step of Sg22, the number of determination values acquired in the step of Sg20 or Sg21 is added to the random number value for internal lottery, and the result of the addition is used as a new random number value for internal lottery. Here, it is determined whether or not an overflow has occurred when the number of determination values is added to the random number for internal lottery (Sg23). If an overflow has occurred, it is determined whether or not the combination is a loss A or a loss B (Sg24). If the combination is either Loss-A or Loss-B, the internal lottery process is terminated and the process returns to the flowchart of FIG. If the winning combination is neither lost A nor lost B, the winning flag for the winning combination is set in the RAM 41c (Sg25). Then, the internal lottery process is terminated, and the process returns to the flowchart of FIG.

  If no overflow has occurred in the step of Sg23, it is determined whether or not there is a combination that has not yet been processed (Sg26). If there is a combination that has not yet been processed, the process returns to the processing of Sg17, and the processing is continued with the next combination from the special combination (including the special combination lost) determined for the normal gaming state as the processing target. If there is no combination not to be processed, the internal lottery process is terminated and the process returns to the flowchart of FIG.

  In the step of Sg5, if the current gaming state is not the normal gaming state, it is determined whether or not it is a small role game (Sg27). If it is a small role game, in correspondence with the small role game, the combinations registered in the winning combination table according to gaming state in FIG. 6A are sequentially read (Sg28), and the process proceeds to Sg30. If it is not a small role game in the step of Sg27, since it is a regular bonus, the combinations registered in the winning combination table according to gaming state in FIG. 6A corresponding to the regular bonus are sequentially read (Sg29), and Sg30 Proceed to the process.

  In the step of Sg30, it is determined whether or not the type of the combination read in the steps of Sg28 and Sg29 is regular bonus (2) or JACIN. In the case of regular bonus (2) or JACIN, whether the winning flag of regular bonus (2) has already been set in the RAM 41c in the previous game or not, and it is determined whether it has been carried over without winning based on the winning flag (Sg31). If the type of the read combination is neither regular bonus (2) nor JACIN, the process proceeds to Sg32.

  If the winning flag for the regular bonus (2) has already been set, the internal lottery process is terminated and the process returns to the flowchart of FIG. 26 (Regular Bonus (2) and JACIN are selected by gaming state as described above). Since it is registered after the small role in the table, the internal lottery process is completed.) Even if the type of the read combination is regular bonus (2) or JACIN, if the winning flag for regular bonus (2) is not set, the process proceeds to Sg32.

  In step Sg32, the number of BETs (number of bets) set in step Sd1 is further read, and the combination corresponding to the combination and the read BET number is obtained from the corresponding role-specific table in FIGS. 6B and 6C. Get the setting status of the common flag. As a result, it is determined whether or not a common flag is set for the combination and the BET number (Sg33).

  If the common flag is set, the number of determination values stored in the address registered in the corresponding role-specific table in FIGS. 6B and 6C is acquired for the role and the BET number (Sg34). . Then, the process proceeds to Sg36. If the common flag is not set, the determination stored in the address registered in the corresponding role table in FIGS. 6B and 6C corresponding to the setting value read for the role and the BET number. The number of values is acquired (Sg35). Then, the process proceeds to Sg36.

  In the step of Sg36, the number of determination values acquired in the step of Sg34 or Sg35 is added to the random number value for internal lottery, and the result of addition is used as a new random number value for internal lottery. Here, it is determined whether or not an overflow has occurred when the number of determination values is added to the random number value for internal lottery (Sg37). If an overflow occurs, the winning flag for the combination is set in the RAM 41c (Sg38). Then, the internal lottery process is terminated, and the process returns to the flowchart of FIG.

  If no overflow has occurred in the step of Sg37, it is determined whether or not there is a combination that has not yet been processed among the combinations determined for the gaming state (Sg39). If there is a combination that has not yet been processed, the process returns to Sg27, and the process continues with the next combination defined for the gaming state as the processing target. If there is no combination not to be processed, the internal lottery process is terminated and the process returns to the flowchart of FIG.

  As described above, in the internal lottery process, it is confirmed whether or not the set value stored in the set value work of the RAM 41c is an appropriate value. An error code indicating an error is set, and the process proceeds to error processing. As in the case where it is determined that the data in the RAM 41c is not normal at the time of startup, an error state due to a RAM abnormality error occurs and the progress of the game is disabled. It has become.

  Also, in the normal gaming state, since the random number for the same internal lottery is drawn separately for the small role and the re-playing role and the special role, the random number to be won in the normal gaming state A small combination (cherry and watermelon in this embodiment) and a special combination (in this embodiment, big bonuses (1) to (3)) may be won simultaneously.

  Next, the random number acquisition process in step Sg1 will be described in detail based on the flowchart of FIG. In the random number acquisition process, first, interrupts are prohibited (Sh1). Next, a sampling command is output to the sampling circuit 43, the random number generated by the random number generation circuit 42 is latched, and the value of the latched random number is input from the I / O port 41d and extracted. The random number value extracted from the random number generation circuit 42 is stored in the general-purpose register 41GR (Sh2).

  Next, the lower byte value and upper byte value of the random number stored in the general-purpose register 41GR are exchanged with each other using the work area of the RAM 41c (Sh3). Next, the value of the random number stored in the general-purpose register 41GR is ORed with 8080h (Sh4). Further, the upper byte (15th to 8th bits) is shifted downward by 1 bit, and 1 is inserted into the empty 15th bit. At this time, the value stored in the general-purpose register 41GR is acquired as a random number for internal lottery and stored in a predetermined area of the RAM 41c (Sh5). Then, after permitting the interrupt prohibited in the step of Sh1 (Sh6), the random number acquisition process is terminated and the process returns to the flowchart of FIG.

  FIG. 34 is a flowchart showing the control contents of the winning determination process executed by the CPU 41a in step Sd5.

  In the winning determination process, first, in correspondence with the current gaming state, the combinations registered as winning determination targets in the gaming state winning combination table in FIG. 6A are sequentially read (Si1), and the read combination It is determined whether or not the combinations are aligned on the effective line (Si2). If the combination of the combination is not aligned on the effective line, the process proceeds to Si4. If the combination of the combination is aligned on the effective line, a winning flag indicating that the combination has won is set in the RAM 41c ( Si3), Si4 processing proceeds.

  In the step of Si4, it is determined whether or not there is a combination that has not been processed yet among the combinations that are determined as winning determination targets for the gaming state. If there is a combination that has not yet been processed, the process returns to the processing of Si1, and the process continues with the next combination registered in the winning combination table according to gaming state as the processing target. If there is no combination not to be processed, the winning flag is referred to determine whether or not the replay has won (Si5). If the replay has not won, the process proceeds to Si7, and if the replay has won, the replay is performed. A replay game in-progress flag indicating that a game is in progress is set in the RAM 41c (Si6), and the process of Si7 proceeds.

  In step Si7, it is determined whether or not the big bonus has been won by referring to the winning flag. If the big bonus has not been won, the process proceeds to Si10. If the big bonus has been won, A big bonus medium flag indicating that it is present is set in the RAM 41c, the big bonus winning flag is cleared (Si8), and the value of the big bonus medium payout counter in which the total number of medals paid out in the big bonus is stored in the RAM 41c (Si9), after setting the above-mentioned effect waiting time for the BB winning effect in the RAM 41c (Si10), the process proceeds to Si11.

  In the step of Si11, it is determined whether or not the regular bonus has been won by referring to the winning flag. If the regular bonus has not been won, the winning determination process is terminated and the process returns to the flowchart of FIG. If the regular bonus has been won, a regular bonus medium flag indicating that the regular bonus is in effect is set in the RAM 41c, the regular bonus winning flag is cleared (Si12), and the number of regular bonus games is stored in the RAM 41c. After initializing the value of the regular bonus game number counter and the value of the regular bonus winning counter in which the number of winnings in the regular bonus is stored (Si13), the winning determination process is terminated and the process returns to the flowchart of FIG.

  FIG. 35 is a flowchart showing the control contents of the game end process executed by the CPU 41a in step Sd7.

  In the process at the end of the game, first, it is determined whether or not a bonus is in effect, that is, whether a regular bonus or a big bonus is in effect (Sj1). If the bonus is in progress, the values of various counters used in the bonus (the above-mentioned big bonus medium payout counter, regular bonus game number counter, regular bonus medium winning counter) are updated (Sj2). Proceed to processing.

  In step Sj3, it is determined whether or not the game is a replay game. If the game is not a replay game, the process proceeds to Sj5. If the game is a replay game, the replay game flag set in the RAM 41c is cleared. The process proceeds to (Sj4) and Sj5.

  In step Sj5, it is determined whether or not the game is in the big bonus. If the game is in the big bonus, whether or not the big bonus ending condition is satisfied, that is, the total number of payouts in the big bonus is 465. (Sj6), and if the big bonus is not in effect at step Sj5, or if the big bonus end condition is not satisfied at step Sj6, the process proceeds to step Sj10, and step Sj6 If the big bonus end condition is satisfied, after setting the ending effect waiting time in the RAM 41c (Sj7), the big bonus medium flag set in the RAM 41c is cleared (Sj8). Initial stage to initialize general work in addition to unused area and unused stack area After 2 (Sj9), the process proceeds to Sj10.

  In step Sj10, it is determined whether or not the game is in a regular bonus. If it is in a regular bonus, whether or not the regular bonus end condition is satisfied, that is, the number of regular bonus games is 12 games. Whether the number of winnings in the regular bonus reaches 8 times, and if the regular bonus provided during the big bonus, the total number of payouts in the big bonus exceeds 465, (Sj11), if the regular bonus is not in the step of Sj10, or if the regular bonus termination condition is not satisfied in the step of Sj11, the process proceeds to the process of Sj13, and the termination condition of the regular bonus in the step of Sj11 Is established in the RAM 41c. Clear the regular bonus flag that are (Sj12), the process proceeds to Sj13.

  In step Sj13, it is determined whether or not the game state of the next game is a regular bonus. If the game state of the next game is a regular bonus, the specified value of the bet number set in the RAM 41c is set to 1 (Sj14). ), The process proceeds to Sj16. When the game state of the next game is not a regular bonus, that is, when the next game is a normal game state or a small role game in the big bonus, the specified value of the bet number set in the RAM 41c is set to 3 (Sj15), The process proceeds to Sj16.

  In step Sj16, after clearing the winning flags other than the special role set in the RAM 41c, initialization 4 for initializing the unused area and the unused stack area in the RAM 41c is performed (Sj17), and the process at the end of the game is performed. When finished, the process returns to the flowchart shown in FIG.

  FIG. 36 is a flowchart showing the control content of the freeze process executed by the CPU 41a in step Sd8.

  In the freeze process, first, it is determined whether or not the finished game is a game in which a big bonus prize has occurred (Sk1). If the game has a big bonus prize, the process proceeds to Sk12. If the game is not a game with a big bonus winning, and if it is not a game with a big bonus winning, it is determined whether or not the finished game is a big bonus ending game (Sk2). If not, the freeze process is terminated and the process returns to the flowchart shown in FIG.

  In the step of Sk2, if it is a big bonus end game, the setting status of a specific register of the CPU 41a is further checked to determine whether or not the stop function is enabled (Sk3). If the stop function is not set to be valid, the process proceeds to Sk12.

  If the stop function is set to be valid in step Sk3, it is determined whether or not the value of the credit counter is 0 (Sk4). If the value of the credit counter is not 0, the operation of the settlement switch 10 is detected. If the operation of the settlement switch 10 is detected (Sk5), the settlement process shown in FIG. 29 is executed (Sk6). After the settlement process is executed, the process returns to the step Sk4. Further, when the value of the credit counter is 0 in the step of Sk4, or when the operation of the settlement switch 10 is not detected in the step of Sk5, from the end point of the game based on the time set at the time of winning determination. It is determined whether or not the waiting time for the ending effect has elapsed (Sk7). If the waiting time for the ending effect has not elapsed, the process returns to Step Sk4, and if the waiting time for the ending effect has elapsed. , Transition to the stop state.

  In the stop state, “END” is displayed on the game auxiliary display 12 (Sk8), whether or not the operation of the reset / setting switch 38 is detected (Sk9), and the operation of the reset / setting switch 38 is performed. If not detected, it is further determined whether or not an operation of the reset switch 23 is detected (Sk10). If an operation of the reset switch 23 is not detected, the process returns to the step of Sk5. In other words, when the stop state is entered, the game waits in a state where the progress of the game is impossible until the operation of the reset / setting switch 38 or the reset switch 23 is detected. During this time, if the value of the credit counter is not 0, that is, if the credit remains, the adjustment process is performed by detecting the operation of the adjustment switch 10.

  In addition, when the operation of the reset / setting switch 38 is detected in the step of Sk9, or when the operation of the reset switch 23 is detected in the step of Sk10, the “END” display on the game auxiliary display 12 is canceled. Then (Sk11) ends the freeze process and returns to the flowchart shown in FIG.

  If the game is a game in which a big bonus prize has occurred in the step of Sk1, or if the game is an end game of the big bonus in the step of Sk3 and the stop function is not set to be effective, It is determined whether or not the value of the credit counter is 0 (Sk12). If the value of the credit counter is not 0, it is determined whether or not the operation of the settlement switch 10 is detected (Sk13). If it is detected, the settlement process shown in FIG. 29 is executed (Sk14), and after the settlement process is executed, the process returns to the step Sk12. In addition, when the value of the credit counter is 0 in the step of Sk12 or when the operation of the settlement switch 10 is not detected in the step of Sk13, the game ends from the end time based on the time set at the time of winning determination. It is determined whether or not the waiting time for the BB winning effect or the ending effect has elapsed (Sk15). If the waiting time for the BB winning effect or the ending effect has not elapsed, the process returns to the step of Sk12 and the BB winning is performed. If the production waiting time of the time production or the ending production has elapsed, the freeze process is terminated and the process returns to the flowchart shown in FIG.

  Next, the control contents of initialization 1 to 4 executed by the CPU 41a in response to the establishment of the initialization condition will be described based on the flowcharts of FIGS.

  FIG. 37 is a flowchart showing the control contents of initialization 1 executed by the CPU 41a before the transition to the setting change mode in the startup process.

  In initialization 1, first, the initialization table of the ROM 41b is referred to, and the start address and initialization size registered corresponding to initialization 1 are read (Sm1). A pointer is set to the read start address (7E00 (H)) (Sm2). Next, the size of the unused stack area (M = stack pointer−7FD2 (H)) is calculated (Sm3), and the number of bytes (1DM (H) + M) of the area to be initialized is set (Sm4). Then, a RAM clear process for clearing data from the start address set in Sm2 over the number of bytes set in Sm4 is executed (Sm5), and when the RAM clear process is completed, the initialization 1 is completed. Return to.

  FIG. 38 is a flowchart showing the control contents of the RAM clear process executed in step Sm5 of FIG.

  In the RAM clear process, 1-byte data indicated by the address indicated by the pointer is cleared to 0 (Sn1), and the initialization byte number (the number of bytes set as an area to be initialized) is decremented by 1 (Sn2). Next, it is determined whether or not the number of initialized bytes after subtraction has become 0, that is, whether or not the initialization of all the specified number of bytes has been completed (Sn3). If the number of initialized bytes after subtraction is not 0, the pointer is advanced by 1 (Sn4), the process returns to Sn1, and the processes of Sn1 to 4 are repeated until the number of initialized bytes becomes 0. If the initialization byte number after subtraction is 0 in the Sn3 step, the initialization of all the specified number of bytes is completed, so the RAM clear process is terminated and the process returns to the original process. .

  FIG. 39 is a flowchart showing the control contents of initialization 2 executed by the CPU 41a at the end of the big bonus in the game end processing of Sd7.

  In the initialization 2, first, after interrupting is prohibited (Sp1), the initialization table of the ROM 41b is referred to, and the start address and the initialization size registered corresponding to the initialization 2 are read (Sp2). In initialization 2, since two start addresses and initialization sizes corresponding to the two start addresses are registered, a pointer is set at the start address (7E28 (H)) of the area to be initialized first among the read start addresses. (Sp3), sets the number of bytes (67 (H)) of the area to be initialized first (Sp4), and clears the data from the start address set in Sp3 over the number of bytes set in Sp4. (See FIG. 38) is executed (Sp5). When the RAM clear process is completed, a pointer is set to the start address (7EBA (H)) of the second area to be initialized among the read start addresses (Sp6), and the size of the unused stack area (M = stack pointer− 7FD2 (H)) is calculated (Sp7), and the number of bytes (118 (H) + M) of the second area to be initialized is set (Sp8). Then, a RAM clear process (see FIG. 38) for clearing data from the start address set in Sp6 over the number of bytes set in Sp8 is executed (Sp9). When the RAM clear process is completed, it is prohibited in the step of Sp1. The interrupt that has been made is permitted (Sp10), and the process returns to the original process even after the initialization 2 is completed.

  FIG. 40 is a flowchart showing the control contents of initialization 3 executed when the data in the RAM 41c is normal in the startup process by the CPU 41a.

  In the initialization 3, first, the initialization table in the ROM 41b is referred to, and the start address and the initialization size registered corresponding to the initialization 3 are read (Sq1). Since two start addresses and initialization sizes corresponding to the two start addresses are registered in initialization 3, a pointer is set at the start address (7EB7 (H)) of the area to be initialized first among the read start addresses. (Sq2), the number of bytes (3 (H)) of the area to be initialized first is set (Sq3), and the data is cleared from the start address set in Sq2 over the number of bytes set in Sq3. (See FIG. 38) is executed (Sq4). When the RAM clear process is completed, the pointer is set to the start address (7F05 (H)) of the second area to be initialized among the read start addresses (Sq5), and the size of the unused stack area (M = stack pointer− 7FD2 (H)) is calculated (Sq6), and the number of bytes (CD (H) + M) of the second area to be initialized is set (Sq7). Then, a RAM clear process (see FIG. 38) for clearing data from the start address set in Sq5 over the number of bytes set in Sq7 is executed (Sq8). When the RAM clear process ends, initialization 3 ends. Return to the original process.

  FIG. 41 is a flowchart showing the control contents of initialization 4 executed for each game by the CPU 41a in the game end process of Sd7.

  In the initialization 4, first, interrupts are prohibited (Sr1), and the start address and the initialization size registered corresponding to the initialization 4 are read with reference to the initialization table of the ROM 41b (Sr2). A pointer is set to the read start address (7F05 (H)) (Sr3). Next, the size of the unused stack area (M = stack pointer−7FD2 (H)) is calculated (Sr4), and the number of bytes (CD (H) + M) of the area to be initialized is set (Sr5). Then, a RAM clear process (see FIG. 38) for clearing data from the start address set in Sr3 over the number of bytes set in Sr5 is executed (Sr6). When the RAM clear process is completed, it is prohibited in the Sr1 step. The interrupt that has been made is permitted (Sr7), and the process returns to the original process even after the initialization 4 is completed.

  42 and 43 are flowcharts showing the control contents of the timer interrupt process executed by the CPU 41a by interrupting the start process or the game process in response to the occurrence of the interrupt 3, that is, at an interval of 0.56 ms.

  In the timer interrupt process, interrupts are first prohibited (Ss1). That is, the execution of another interrupt process during the execution of the timer interrupt process is prohibited. Then, the register in use is saved in the stack area (Ss2).

  Next, the branch counter for identifying the timer interrupt to be executed in the timer interrupt process is advanced by 1 from the four types of timer interrupts 1 to 4 (Ss3). In the step of Ss3, 1 is added when the branch counter value is 0 to 2, and is updated to 0 when the counter value is 3. That is, the branch counter value loops in the order of 0 → 1 → 2 → 3 → 0... Each time the timer interrupt process is executed.

  Next, the branch counter value is referenced to determine whether it is 2 or 3, that is, timer interrupt 3 or timer interrupt 4 (Ss4). If it is not timer interrupt 3 or timer interrupt 4, that is, timer interrupt In the case of 1 or timer interrupt 2, it is checked whether the reel motors 32L, 32C, 32R are started or whether they are rotating at a constant speed, and whether the reel motors 32L, 32C, 32R are started or are rotating at a constant speed. For example, the motor phase signal output process for outputting the phase signal data changed in the motor step process of Ss8 described later and the phase signal data changed in the final stop process of Ss23 described later is executed (Ss5).

  Next, it is determined whether or not it is 1 by referring to the minute counter value, that is, whether or not it is a timer interrupt 2 (Ss6). If it is not a timer interrupt 2, that is, if it is a timer interrupt 1, it is a reel motor. Reel start processing (Ss7) for controlling the step time interval when starting 32L, 32C, 32R, motor step processing (Ss8) for changing phase signal data of the reel motors 32L, 32C, 32R, reel motors 32L, 32C After the stop of 32R, the motor phase signal standby process (Ss9) for changing the phase signal to one-phase excitation after a predetermined time has been sequentially executed, and then the register saved in the stack area in Ss2 is restored (Ss20). The interrupt prohibited in the step is permitted (Ss21), and the process returns to the state before the interrupt.

  In the case of timer interrupt 2 in step Ss6, LED dynamic display processing (Ss10) for dynamically lighting various indicators, and output processing for control signals and the like for outputting data such as lighting signals for various LEDs to the output port (Ss11), random number update process for updating various software random numbers (Ss12), time counter update process for updating various time counters (Ss13), command transmission for transmitting commands stored in the command queue to the effect control board 90 After sequentially executing the processing (Ss14) and the external output signal update processing (Ss15) for updating the external output signal, the register saved in the stack area in Ss2 is restored (Ss20), and the interrupts prohibited in the step of Ss1 are permitted. Then (Ss21), the process returns to the state before the interruption.

  If the timer interrupt 3 or the timer interrupt 4 is found in the step of Ss4, it is further determined by referring to the counter value for wake-up 3 whether it is a timer interrupt 4 (Ss16). If it is not interrupt 4, that is, if timer interrupt 3, port input processing (Ss 17) for inputting detection data of various switches from the input port, passing through the origin of reels 2 L, 2 C, 2 R during constant speed rotation After the origin passing process (Ss18) to be checked and the switch input determination process (Ss19) for determining whether or not these various switches satisfy the detection conditions based on the detection signals of the various switches, the stack is stacked in Ss2. The register saved in the area is restored (Ss20), the interrupt prohibited in the step of Ss1 is permitted (Ss21), and the process before the interruption is returned.

  If the timer interrupt is 4 in the step of Ss17, the stop position is determined when the detection of the effective stop switches 8L, 8C, and 8R is determined, and the number of steps after which the stop is calculated is calculated. The number of steps until the stop calculated in the switch process (Ss22) and the stop switch process is counted, and when it is time to stop, the stop process (Ss23) starts the brake by the two-phase excitation, and the brake is started in the stop process. After executing a final stop process (Ss24) for three-phase excitation after a certain period of time, the registers saved in the stack area in Ss2 are restored (Ss20), and the interrupts prohibited in the step of Ss1 are permitted ( Ss21), it returns to the process before interruption.

  FIG. 44 is a flowchart showing the control contents of the command storage process executed when the CPU 41a generates a command in accordance with the progress of the game in the startup process and the game control process and stores it in the command queue.

  The command transmitted by the CPU 41a is composed of 2 bytes. The first byte represents MODE (command classification), and the second byte represents EXT (command content). Further, the form of the command shown in this embodiment is an example, and other data forms may be used. In this embodiment, the command is composed of a 2-byte signal, but these commands may be composed of a 1-byte signal or a 3-byte or more signal.

  In the command storing process, first, MODE and EXT that constitute a command to be transmitted are generated (St1). Then, after storing the generated command in the area of the area number indicated by the storage pointer, that is, in the empty area of the command queue (St2), 1 is added to the area number indicated by the storage pointer (St3). Since the area number is a numerical value in the range of 0 to 15, when the serial number indicated by the storage pointer is 15, 1 is added and updated to 0 when it becomes 16.

  Next, it is confirmed whether or not the untransmitted flag is set (St4). If the untransmitted flag is not set, the untransmitted flag is set (St5). Then, it is checked whether the area number indicated by the storage pointer matches the area number indicated by the transmission pointer, that is, whether all areas of the command queue are filled with unsent commands. In this case, an unsent command stored in the command queue is transmitted, and waits until the area number indicated by the storage pointer does not match the area number indicated by the transmission pointer, and the area number indicated by the storage pointer and the transmission pointer are waited. The command storage process is terminated when the area number indicated by (2) does not match, that is, when the command queue becomes empty (St6).

  FIG. 45 is a flowchart showing the control contents of the command transmission process executed by the CPU 41a in the timer interrupt 2 of the timer interrupt process described above.

  In the command transmission process, first, it is determined whether or not the delay counter for setting the transmission delay time of the command is greater than 0, that is, whether or not the command stored in the command queue is waiting to be transmitted (Su1). ).

  If it is not in the transmission waiting state at Su1, it is determined whether or not the aforementioned untransmitted flag indicating that an untransmitted command is stored in the command queue is set (Su2). If the untransmitted flag is not set in Su2, the command to be transmitted is not stored and the command transmission process is terminated.

  In addition, when the untransmitted flag is set in Su2, that is, when an untransmitted command is stored in the command queue, a random number value randomly generated in the range of 0 to 15 is acquired from the random number counter ( (Su3), 2 is added to the obtained random number value to correct it to a value of 2 to 17 and set in the delay counter (Su4).

  Next, 1 is subtracted from the delay counter value (Su5), whether the delay counter value is larger than 0, that is, whether the transmission delay time of the command stored in the area indicated by the transmission pointer value of the command queue has elapsed, (Su6), and if the delay counter value is greater than 0, that is, if the transmission delay time has not elapsed, the command transmission process is terminated.

  If the delay counter value is 0 in step Su6, that is, if the transmission delay time has elapsed, the command stored in the area indicated by the transmission pointer value of the command queue is transmitted to the effect control board 90 ( Su7-Su10). Specifically, first, the MODE that constitutes the command stored in the area indicated by the transmission pointer value of the command queue is output (Su7), and a strobe signal for notifying the sub-control unit 91 that the command has been output is output for a predetermined time. (In this embodiment, 10 μs) is output (Su8). Then, EXT constituting the command stored in the area indicated by the transmission pointer value is output (Su9), and the strobe signal is output again for a predetermined time (Su10).

  Next, 1 is added to the area number indicated by the transmission pointer (Su11). Since the area number is a numerical value in the range of 0 to 15, when the area number indicated by the transmission pointer is 15, 1 is added and when it becomes 16, the area number is updated to 0.

  Next, it is confirmed whether or not the area number indicated by the transmission pointer matches the serial number indicated by the storage pointer, that is, whether or not the command to be transmitted is stored in the command queue (Su12). Then, the unsent flag is cleared and the command transmission process is terminated (Su13).

  If it is determined at Su1 that the delay counter value is greater than 0, that is, it is in a transmission waiting state, the process proceeds to Su5, and when the transmission delay time has elapsed, the command queue transmission pointer value indicates the area indicated. The stored command is transmitted, and when an untransmitted command becomes empty, processing such as clearing an untransmitted flag is performed (Su5 to Su13), and the command transmission processing is terminated.

  FIG. 46 shows the control contents of the power interruption processing executed by the CPU 41a when the interruption 2 occurs, that is, when the voltage drop signal from the power interruption detection circuit 48 is input, and interrupts the execution processing and game processing. It is a flowchart which shows.

  In the power interruption interruption process, first, interruption is prohibited (Sv1). That is, other interrupt processing is prohibited from being executed at the start of the power interruption interrupt processing. Next, all registers that may be in use are saved in the stack area (Sv2). Note that the values of the I register and IY register described above are used, but are not saved here because the same fixed value is always set with the initialization at the time of startup.

  Next, the detection data of the voltage drop signal is acquired from the input port, and it is determined whether or not the voltage drop signal is input (Sv3). At this time, if the voltage drop signal is not input, the register saved in the stack area in Sv2 is restored (Sv4), the interrupt prohibited in the step of Sv1 is permitted (Sv5), and the process before the interrupt is performed. Return.

  If a voltage drop signal is input in step Sv3, destruction diagnosis data (5A (H) in this embodiment) is set (Sv6), and all output ports are initialized (Sv7). . Next, RAM parity adjustment data is calculated and set so that the exclusive OR of all storage areas (including unused areas and unused stack areas) of the RAM 41c becomes 0 (Sv8), and access to the RAM 41c is performed. It is prohibited (Sv9).

  Then, except for the determination of whether or not the voltage drop signal is input (Sv10, Sv10 is the same process as Sv3), the process enters a loop process in which no process is performed. That is, when the voltage decreases as it is, the operation is stopped internally. Therefore, the CPU 41a reliably stops operation when the power is interrupted. Further, in this loop processing, when the voltage recovers and the voltage drop signal is not input, the above-described startup processing is executed, and if the RAM parity is 0 and the destructive diagnosis data is normal, the original processing is performed. It will return to.

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

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

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

  In the startup process (sub), after initialization of the built-in device, peripheral IC, interrupt mode, stack pointer, etc. (Sw1), access to the RAM 91c is permitted (Sw2). Then, the RAM parity of all storage areas of the RAM 91c is calculated (Sw3), and it is determined whether or not the RAM parity is 0 (Sw4). If the data in the RAM 91c is normal, the RAM parity should be 0. If the RAM parity is 0 in the step Sw4, the data stored in the RAM 91c is normal. (Sw5), interrupt is permitted (Sw7), and the process proceeds to loop processing. That is, it returns to the control state at the time of power interruption. If the RAM parity is not 0 in the step of Sw4, the data stored in the RAM 91c is not normal. Therefore, after initializing the RAM 91c (Sw6), interrupts are permitted (Sw7) and the loop processing is performed. Transition.

  FIG. 48 is a flowchart showing the control contents of the command reception interrupt process executed by the CPU 91a by interrupting and executing another process based on the detection of the strobe signal output from the game control board 40. The strobe signal is a signal input to the interrupt terminal of the sub-control unit 91 at the time of command transmission.

  In the command reception interrupt process, first, interrupts are prohibited (Sx1), and the register is saved in the RAM 91c (Sx2). Then, the detection data of the command transmission line from the input port, that is, the MODE output from the game control board 40 is acquired (Sx3), and it waits until the strobe signal is detected again (Sx4).

  Next, when the strobe signal is detected again, the detection data of the command transmission line from the input port, that is, the EXT output from the game control board 40 is acquired again (Sx5). Then, a command composed of MODE and EXT is stored in a buffer provided in the RAM 91c (Sx6). Then, the saved register is restored in Sx2 (Sx7), the interrupt prohibited in Sx1 is permitted (Sx8), and the state before the interruption is restored.

  FIG. 49 is a flowchart showing the control contents of the timer interrupt process (sub) executed by the CPU 91a at intervals of 1.12 ms based on the count of the internal clock.

  In the timer interrupt process (sub), first, it is determined whether or not a command is stored in the buffer (Sy1). If no command is stored in the buffer, the process proceeds to Sy6. If a command is stored in the buffer, a command is acquired from the buffer (Sy2), and it is determined whether the acquired command is an initialization command. (Sy3). If the acquired command is an initialization command, the RAM 91c is initialized (Sy4), and the process proceeds to Sy14.

  If it is determined in step Sy3 that the acquired command is not an initialization command, it is determined whether or not the acquired command is a winning determination command (Sy5). If the acquired command is not a winning determination command, the process proceeds to Sy8. If it is a winning determination command, it is determined whether or not the winning determination command indicates a big bonus winning (Sy6).

  If the winning determination command does not indicate the big bonus winning in step Sy6, the process proceeds to Sy14. If the winning determination command indicates the big bonus winning, the BB winning pattern (in the BB winning effect) The corresponding effect pattern) is set as an effect pattern in the RAM 91c (Sy7), and the process proceeds to Sy14.

  If it is determined in step Sy5 that the acquired command is not a winning determination command, it is determined whether or not the acquired command is a gaming state command (Sy8). If the acquired command is not a gaming state command, the process proceeds to Sy12. If it is a gaming state command, the gaming state indicated by the gaming state command is set in the RAM 91c (Sy9), and based on the set gaming state. It is then determined whether or not the game is a big bonus end game (Sy10).

  If the game is not a big bonus end game in step Sy10, the process proceeds to Sy12. If the game is a big bonus end game, an ending pattern (effect pattern corresponding to the ending effect) is generated. The pattern is set in the RAM 91c (Sy11), and the process proceeds to Sy14.

  In step Sy12, it is determined whether the acquired command is an internal winning command. If the acquired command is not an internal winning command, the process proceeds to Sy14. If the acquired command is an internal winning command, the command is stored in the ROM 91b. An effect pattern selection process is performed in which an effect pattern is selected at a selection rate corresponding to the result of the internal lottery indicated by the internal winning command, and the selected effect pattern is set in the RAM 91c as the effect pattern of the game. (Sy13), the process proceeds to Sy14.

  In step Sy14, the control pattern table stored in the ROM 91b is referred to, the control pattern setting for reading the effect pattern set in the RAM 91c and the control pattern registered corresponding to the acquired command and setting it in the RAM 91c. The process is performed, and the process proceeds to Sy15.

  In the step of Sy15, in accordance with the control pattern set in the step of Sy14, an effect control process for controlling various effect devices such as the liquid crystal display 51, the effect effect LED 52, the speakers 53 and 54, and the reel LED is executed. Proceed to step.

  In step Sy16, processing for updating the values of various counters such as a random number counter in the RAM 91c is performed, and then the process proceeds to processing in Sy17. In step Sy17, the content of data backed up in the RAM 91c at startup is normal. Thus, the RAM parity adjustment data is calculated and set so that the exclusive OR of all the storage areas of the RAM 91c becomes 0, and the timer interrupt process (sub) is terminated. That is, the CPU 91a does not set the RAM parity adjustment data when the power interruption is detected like the CPU 41a of the main control unit 41, but the RAM parity adjustment data for each timer interrupt process (sub) that is periodically executed. Even if the power is cut off, it is possible to determine whether or not the content of the data backed up in the RAM 91c at the time of recovery is normal.

  Next, operation states of the CPU 41a of the main control unit 41 and the CPU 91a of the sub control unit 91 during a power failure will be described based on the timing chart of FIG.

  First, the power interruption detection circuit 48 outputs a voltage drop signal to the main control unit 41 when a + 25V DC voltage (hereinafter referred to as a power supply monitoring voltage) becomes + 18V or less (ta1). If the CPU 41a is executing a setting change process or a game process when the voltage drop signal is input, the CPU 41a interrupts the game process to execute the power interruption interrupt process. When a voltage drop signal is input simultaneously with the request for timer interrupt processing (interrupt 3), the power interruption interrupt processing is executed with priority over the power interruption interrupt processing over the timer interrupt processing. Further, when the voltage drop signal is input while the CPU 41a is executing the timer interrupt process, the power interruption interrupt process is executed when the timer interrupt process being executed is completed (ta2). In this embodiment, the CPU 41a is driven after the power monitoring voltage becomes + 18V at which the voltage drop signal is output, rather than the sum of the maximum time required for the timer interrupt process and the maximum time required for the power interruption interrupt process. Since the time to drop to the voltage (+ 5V) (ta3) that can be generated is longer, even when the CPU 41a is executing the timer interrupt process at the time of a power failure, it guarantees the time when the power interrupt process can be performed reliably It has come to be.

  Further, + 12V (VCC), which is the source of the power supply voltage (+5 V (VCC)) of the sub-control unit 91, is delayed in voltage drop by the capacitor 309 mounted on the power supply board 100 even during a power failure. The CPU 91a is buffered until a time sufficient for buffering the command transmitted in the timer interrupt process at the time of the power failure and acquiring the buffered command in the subsequent timer interrupt process (sub) (ta4). Since the voltage (+ 7V) that can be driven is maintained, even when the command is buffered from the game control board 40 at the time of a power failure, the time for reliably acquiring the command and reflecting it as data to be backed up in the RAM 91c It has come to be secured. In this embodiment, a voltage that can drive the CPU 91a is maintained until a time of 20 ms or more has elapsed from the time when the power monitoring voltage becomes +18 V or less. It is only necessary to maintain a voltage capable of driving the CPU 91a over a time equal to or longer than the execution interval of the CPU 2 (a time sufficient for the CPU 91a to reliably acquire a command).

  As described above, in the slot machine 1 of the present embodiment, the unused area in the RAM 41c of the main control unit 41 is initialized for each game, so that the malicious program is stored using the unused area of the RAM 41c. However, it is possible to prevent the unauthorized program from being resident.

  Further, in this embodiment, the unused stack area in the stack area is initialized for each game in addition to the unused area in the RAM 41c, so that all the unused areas in the RAM 41c at that time are stored for each game. For example, even if it is attempted to store an illegal program using an unused stack area without using an unused area of the RAM 41c, there is no room for the illegal program to reside. Therefore, it is possible to more reliably prevent the unauthorized program from being resident, and for example, to add unauthorized data (such as an address specified by the unauthorized program) to the unused stack area, causing the microcomputer to malfunction when the data is restored. By rewriting the register to an illegal one, the original program Fraud can be prevented that would carry out the operation different from the. Further, by storing illegal data in the unused stack area, an area where the saved data should be stored can be compressed, the stack area overflows, and the micro that configures the main control unit 41 is stored. Problems such as the computer running away can be prevented.

  In this embodiment, the initialization area 4 for initializing the unused area and the unused stack area of the RAM 41c is executed every game at the end of the game, so that the unused area and the unused stack area of the RAM 41c are changed for each game. If the unused area and / or the unused stack area of the RAM 41c is initialized at least once per game, but the unused area and / or the unused stack area of the RAM 41c is initialized. The timing for performing the conversion may be any timing during one game. For example, the unused area and / or the unused stack area of the RAM 41c may be initialized at the start of the game or when a process that is always executed for each game is executed. It may be one that performs the conversion.

  Also, before the start of setting (before transition to the setting change mode), at the end of the big bonus, when the data in the RAM 41c is not destroyed at the time of activation, when the four initialization conditions at the end of one game are satisfied, In addition to performing four types of initialization 1 to 4 which are initialized in different areas depending on each initialization condition, any of the four types of initialization conditions is satisfied, and an unused area in the RAM 41c is always Since the unused stack area in the stack area is initialized, it is possible to more reliably prevent the illegal program from being resident.

  In particular, when the data in the RAM 41c is not destroyed at the time of startup, the unused area in the RAM 41c and the unused stack area in the stack area are always initialized. Therefore, the unused area and the unused stack area in the RAM 41c are used. Even when an unauthorized program or unauthorized data is stored, the control state of the main control unit 41 can be prevented from returning based on the data in the RAM 41c while the unauthorized program or the unauthorized data is stored.

  The ROM 41b of the main control unit 41 registers the start address of the area to be initialized and the initialization size indicating the size of the area to be initialized, corresponding to the initializations 1 to 4, and the CPU 41a stores the RAM 41c. When initialization is performed, the initialization table is referred to, the start address and initialization size corresponding to any of initializations 1 to 4 are obtained according to the initialization condition, and a pointer is set to the start address. The initialization size is set (if the initialization size includes the size of the unused stack area, the size of the unused stack area (stack pointer-7FD2 (H)) is calculated and the initialization size is set. ). Then, the area of the address corresponding to each byte from the initialization address where the pointer is set is cleared to 0, and each time the byte is cleared, the initialization size is decremented by 1 and the pointer is advanced by 1. Run until zero. That is, when the CPU 41a initializes the RAM 41c, it does not initialize each area according to the initialization condition, but initializes an area of a specified size from a specified address.

  Therefore, by setting only the start address corresponding to the type of initialization condition and the size of the area initialized at that time in the initialization table of the ROM 41b, the initialization end corresponding to the type of initialization condition is completed. The area corresponding to the type of initialization condition can be initialized without individually setting addresses, and multiple types of initialization can be performed using a common process (RAM initialization process). The capacity of the program for performing multiple types of initialization can be reduced. Further, in the RAM initialization process, the end of the process is determined only by determining whether or not the initialization size is 0. Therefore, the end of the process is determined by comparing the address of the currently initialized byte with the end address. Compared to the case, the processing load can be greatly reduced.

  Further, interrupts are always prohibited during the initializations 1 to 4, and a voltage drop signal is output from the power interruption detection circuit 48 while the data stored in the RAM 41c is being initialized. Even if it is input, the power interruption interrupt process is not executed until the initialization is completed. For example, the power interruption interrupt process is performed at a stage before the initialization is completely completed. It is possible to prevent problems such as initialization data and non-initialization data mixed among power data, and a normal return to the control state before power interruption cannot be performed at the time of recovery.

  In addition, in the power interruption interrupt processing, after destructive diagnosis data with any bit set to 1 is stored in a predetermined address of the RAM 41c, the RAM parity based on all data including the unused area and the unused stack area of the RAM 41c. RAM parity adjustment data is calculated and stored so that becomes 0, and RAM parity calculated based on data stored in all areas including the unused area and unused stack area in the RAM 41c at the time of restoration Whether or not destructive diagnosis data is stored, and if the RAM parity is not 0, or even if the RAM parity is 0, the destructive diagnosis data is stored normally. If not, an error occurs due to a RAM error, and the setting key switch 37 is turned on and the power is turned on. Until the initialization 1 for initializing all areas except the used stack area of the RAM 41c is performed, the progress of the game is impossible. Therefore, the unused area and / or the unused stack area of the RAM 41c at the time of startup. Even if a malicious program is stored in the computer, the malicious program can be found and initialized.

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

  Further, in this embodiment, when determining whether or not winning is allowed in the internal lottery process, the set value stored in the set value work of the RAM 41c is an appropriate value (a value in the range of 1 to 6). If not, it is not determined whether or not the winning is allowed with the probability based on the default setting value (for example, setting 1). In this case as well, the error state due to the RAM abnormal error is controlled, and the game If the progress is disabled, the mode is changed to the setting change mode, and the setting value is not newly selected / set based on the setting change operation, the state where the progress of the game is disabled is not released. In other words, even when it is not possible to properly determine whether or not winning is allowed in the internal lottery process, the game may be played based on the setting value selected and set based on the setting change operation. Since it is secured, the fairness of the game can be achieved.

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

  In this embodiment, the RAM parity adjustment data is calculated and stored so that the result of the exclusive OR operation is 0 based on all the data in the RAM 41c in the power interruption processing, that is, Since it is determined whether or not the data in the RAM 41c is normal by determining whether or not the RAM parity calculated based on the data stored in all the areas in the RAM 41c at the time of recovery is 0, the determination is made as follows. It can be performed accurately and conveniently.

  In this embodiment, in the power interruption interrupt processing, destruction diagnosis data (in this embodiment, 5A (H)) in which any bit is 1, that is, specific data other than 0 is stored in the RAM 41c. In addition to determining whether or not the RAM parity is 0 at the time of start-up, the RAM parity is stored based on all the data in the RAM 41c including the destruction diagnosis data. It is determined whether or not the data for destructive diagnosis is normally stored. If the RAM parity is 0 and the data for destructive diagnosis is also stored normally, the data in the RAM 41c is normal. Determination is made and the control state is restored based on the data stored in the RAM 41c. As a result, when 00 (H) is stored in all areas, that is, when the data in the RAM 41c is cleared to 0 even if the data in the RAM 41c is not normal, the determination of the RAM parity at the time of startup is performed. However, if the data in the RAM 41c has been cleared to 0, the area in which the destructive diagnosis data is to be stored is also 0, and it is determined that the data in the RAM 41c is not normal. Since it can be prevented that the data in the RAM 41c is erroneously determined to be normal, it is possible to further increase the accuracy of determining whether or not the data in the RAM 41c has the correct contents at the time of activation.

  Further, when the CPU 41a determines that the RAM parity is 0 at startup and the data for destructive diagnosis is also normally stored, and determines that the data in the RAM 41c is normal, the destructive diagnosis stored in the RAM 41c. Since the data for destruction diagnosis is still stored in the RAM 41c even after the activation, the data in the RAM 41c is not normal at the next activation, but the data is destroyed. Since diagnostic data is stored, it is possible to prevent erroneous determination as normal.

  Further, in this embodiment, when an abnormality occurs in the data in the RAM 41c and the progress of the game is disabled, a setting value changing operation as a condition for canceling the disabled state of the game is effective. As a result of the transition to the setting change mode (setting change processing), all the areas except the used stack area of the RAM 41c are initialized, so that the initial data of the RAM 41c due to the occurrence of an abnormality And initialization of data associated with selection / setting of set values can be performed at once, and unnecessary processing can be omitted. Further, when the CPU 41a is activated, it is determined whether or not the setting key switch 37 is ON before determining whether the data in the RAM 41c is normal. At that time, the setting key switch 37 is ON. If it is determined that there is, the determination as to whether the data in the RAM 41c is normal is not performed, and the mode shifts to the setting change mode, where a new setting value is selected and set. It can be omitted.

  In this embodiment, initialization 1 for initializing all areas except the used stack area of the RAM 41c is performed before shifting to the setting change process. However, along with the shift to the setting change process. Initialization 1 may be performed, for example, after the setting change process is completed, or may be performed when the setting value is confirmed in the setting change process. In this case, since the inconvenience arises when the determined set value is changed, in initialization 1, all areas except the used stack area and the set value work of the RAM 41c are initialized. Become.

  Further, in this embodiment, once the error state due to the RAM abnormality error is controlled, the game is disabled until the setting change process is performed, but the error state due to the RAM abnormality error occurs. When initialization is performed, all areas except the used stack area of the RAM 41c are initialized, and a set value is set to an initial value (for example, set value 1), and a reset operation is performed in this state. Thus, the game may be restarted.

  Further, in this embodiment, when determining whether or not winning is allowed in the internal lottery process, the set value stored in the set value work of the RAM 41c is an appropriate value (a value in the range of 1 to 6). If not, the RAM abnormal error state is also controlled in this case, but the setting value stored in the setting value work of the RAM 41c is not an appropriate value (a value in the range of 1 to 6). In this case, it may be determined whether or not winning is allowed with a probability based on an initial value of the set value (for example, set value 1).

  In this embodiment, the CPU 41a transmits a command corresponding to the progress of the game to the effect control board 90, and the sub-control unit 91 mounted on the effect control board 90 receives the command transmitted from the game control board 40. Since the CPU 41a does not need to control the presentation only by sending a command, the processing load on the CPU 41a can be reduced and the presentation can be made various. .

  Further, a command transmission line for transmitting a command from the game control board 40 to the effect control board 90 is connected between the game control board 40 and the effect control board 90 via the effect relay board 80, and the game control board Since the production control board 90 is not directly connected to 40, it is possible to prevent an illegal signal from being input from the command transmission line to the CPU 41a from the outside and affecting the control of the game.

  The CPU 41a sets the value of the delay counter at random when transmitting the command, and transmits the command when the delay counter value becomes 0, and the transmission timing of the command is a predetermined time. In the range (2.24 to 35.84 ms), the effect control board 90 side performs an effect that assists the eye based on the reception timing of the command transmitted from the game control board 40. Can be prevented

  In this embodiment, the command transmission timing is delayed in the range of 2.24 to 35.84 ms. At least the symbol of the reels 2L, 2C, and 2R has a maximum delay time of 1 symbol. Anything that exceeds the time required for movement is sufficient.

  Even when a plurality of commands are transmitted continuously, these commands are stored in the command queue provided in the RAM 41c in the order in which they are generated, and each command is transmitted in its generation order, that is, the command is originally transmitted. Since it is transmitted in the order of power, the production control board 90 side can perform the production by grasping the control state of the CPU 41a in the exact order, and the player feels uncomfortable due to a discrepancy in the production order. Can be prevented.

  In addition, when a power failure occurs in a state where command transmission is delayed, that is, in a command transmission waiting state, and a power interruption interrupt process is performed, the command, transmission pointer, and storage pointer stored in the command queue All of the delay counter values are backed up in the RAM 41c, and at the time of recovery, command transmission control is performed in the state of the command, transmission pointer, storage pointer, and delay counter value stored in the command queue backed up in the RAM 41c. Thus, even if a power failure occurs while waiting for command transmission, the command transmission control can be resumed from the power failure state at the time of recovery, so that the control of the CPU 41a can be simplified.

  In this embodiment, when a power failure occurs while waiting for transmission of a command transmission command, and the power failure is restored, command transmission control is resumed from the state at the time of the power failure. When a power failure occurs while waiting for command transmission, the delay counter value is newly reset after the recovery, and the delay time based on the reset delay counter value has been reset. Sometimes it may be sent. In other words, if there is a command waiting to be transmitted at the time of recovery, the command may be transmitted when a newly set delay time elapses at the time of recovery. However, the command transmission timing can be changed reliably.

  Further, in this embodiment, when the voltage drop signal is input to the trigger terminal CLK / TRG, the CPU 41a interrupts the process being executed and executes the power interruption process. In the process including the process for setting the data for destructive diagnosis and the process for calculating and setting the data for adjusting the RAM parity, the process for making it possible to determine whether the data in the RAM 41c is normal at the time of recovery or the initial setting of the output port Before performing the conversion, it is determined whether or not a voltage drop signal is input to the signal input terminal DATA. If the voltage drop signal is also input to the signal input terminal DATA, the data in the RAM 41c is normal at the time of recovery. If the voltage drop signal is not input to the signal input terminal DATA, the original processing is performed. It is adapted to return.

  That is, the voltage drop signal is input to the two systems of the input unit to the main control unit 41, and the CPU 41a does not perform the power interruption interrupt process when the voltage drop signal is input to one of the input units. Before the process for enabling determination of whether the data in the RAM 41c is normal, the initialization of the output port, or the like is performed, it is determined again whether or not the voltage drop signal is input to the other input unit. These processes are executed only when a voltage drop signal is also input to the input section of this, and when power failure is detected by mistake, whether or not the data in the RAM 41c is normal at the time of recovery is detected. Since it is possible to prevent the process for enabling the determination and the process such as the initialization of the output port from being performed, the control of the CPU 41a may be interrupted for an unnecessarily long time due to erroneous detection of power interruption. More than necessary Possible to prevent the load is applied to.

  In the present embodiment, the voltage monitored by the power interruption detection circuit 48 and the power supply voltage for driving the electrical components connected to the power supply board 100, the game control board 40, and the effect control board 90 are separately provided. Since a stable voltage is monitored by the power interruption detection circuit 48 as compared with the power supply voltage that tends to drop depending on the driving conditions of these electrical components, It is possible to prevent a malfunction such as a voltage drop signal being output along with the voltage drop and an electric interruption interrupt process being performed.

  In addition, other interrupts are prohibited during power interruption interrupt processing and timer interrupt processing. For example, when a voltage drop signal is input during execution of timer interrupt processing. However, double interruptions do not occur, and it is possible to prevent the processing load of the CPU 41a from increasing and data consistency from being lost. In particular, even if a voltage drop signal is input during the transmission of a command, no interruption occurs and the transmission of the command is not hindered, and the transmission can be completed normally before the CPU 41a stops driving. .

  Also, if the interrupt timing for power interruption interrupt processing and the interrupt timing for timer interrupt processing are simultaneous, that is, if interrupt 2 and interrupt 3 occur simultaneously, priority is given to interrupt 2 In addition to executing the interruption interrupt process, if an interruption 2 occurs during the execution of the timer interruption process, the interruption interruption process is executed after the timer interruption process ends. Therefore, the power interruption interrupt process is performed as early as possible while preventing multiple interruptions, so that the power interruption interrupt process can be reliably performed before the driving of the CPU 41a is stopped.

  Further, the CPU 41a can execute four types of interrupts of interrupts 1 to 4, and when interrupts 1 and 4 that are set to unused are generated, the CPU 41a immediately returns to the original process. The unused interrupt processing to be executed is executed. For this reason, even if unused interrupts 1 and 4 occur, the process immediately returns to the process before the interrupt. Therefore, even if an unused interrupt occurs due to noise or the like, the CPU 41a runs out of control. It is possible to prevent such troubles.

  In this embodiment, the CPU 91a of the sub-control unit 91 calculates and sets the RAM parity adjustment data every time the timer interrupt process is executed. In other words, the process for making it possible to determine whether or not the content of the data backed up in the RAM 91c at the time of restoration is performed periodically without depending on the command transmitted from the game control board 40. Even when the command is transmitted with a delay, the CPU 91a does not stop before calculating and setting the RAM parity adjustment data due to the delayed transmission of the command. The CPU 91a can accurately determine whether the data backed up in the RAM 91c is normal.

  In this embodiment, after the CPU 41a transmits a command, the transmission of a new command is prohibited for at least 4.48 ms, and the CPU 91a of the sub-control unit 91 receives the command reliably. In addition, the time for backing up the received command to the RAM 91c can be secured. In this embodiment, 4.48 ms is applied as a time during which transmission of a new command is prohibited, but at least a time sufficient for the CPU 91a to receive the command and to back up the received command to the RAM 91c. If so, a time shorter than 4.48 ms (eg, 2.24 ms) may be applied.

  In this embodiment, +12 V (VCC), which is the source of the power supply voltage {+5 V (VCC)} of the sub-control unit 91, is delayed in voltage drop by the capacitor 309 mounted on the power supply board 100 even during a power failure. At least in the event of a power failure, the CPU 91a of the sub-control unit 91 can be driven until a sufficient time (20 ms in this embodiment) has passed for the CPU 91a to reliably receive the command transmitted in the timer interrupt process. Even if a power failure occurs during command transmission, the CPU 91a can reliably receive the command transmitted at the time of power failure before the drive stops, Longer than the interval at which the command received by the CPU 91a is backed up (timer interrupt processing (sub) execution interval), Since a voltage capable driving the PU91a (+ 7V) is maintained it can be reliably back the received command to the RAM 91c.

  Further, in the slot machine 1 of the present embodiment, in the game in which the big bonus winning has occurred, the prohibition of the credit settlement is canceled when the end of the game is determined. Even during the period when setting of the bet number is prohibited until the elapse of time, medals stored as credits (including medals used for setting the bet number) can be returned. As long as the player's will is reflected, the medal for the credit stored as owned by the player can be returned. Thus, for example, in a game in which a big bonus prize has occurred, before starting the big bonus game accompanying the occurrence of the big bonus prize, a part of the medal stored as credit is given as a prize (for example, a soft drink or a cigarette). Etc.), but it is possible to receive a medal return reflecting such a player's will.

  In addition, when a big bonus prize is generated, a BB winning effect indicating that the big bonus prize has occurred is executed over a period in which the setting of the number of bets is prohibited. It is possible to effectively enhance the interest of the player when shifting to the game.

  Also, in the game where the big bonus end condition is satisfied, the prohibition of credit settlement is canceled when the end of the game is determined, and after the game ends, the bet number is set until the waiting time for the ending effect is over Even during the prohibited period, medals stored as credits (including medals used to set bets) can be returned, so the player's will is reflected as much as possible. Thus, the medal for the credit stored as possessed by the player can be received. This makes it possible to receive a medal return reflecting the will of the player who wants to end the game immediately after the end of the big bonus.

  Also, at the end of the game when the big bonus end condition is satisfied, an ending effect is executed to indicate that the big bonus has ended over the period when the setting of the number of bets is prohibited. can do.

  In addition, even in a game where the big bonus end condition is satisfied, even if the game is controlled to be stopped, the prohibition of credit settlement is canceled when the end of the game is determined, the game ends, and the store clerk performs a reset operation. Medals stored as credits (including medals used to set bets) are returned even during the period when setting of bets is forbidden until the stoppage state is released Therefore, it is possible to receive medals for credits stored as owned by the player, reflecting the player's will as much as possible. This makes it possible to receive a medal return reflecting the will of the player who wants to end the game immediately after the end of the big bonus.

  Further, in the slot machine 1 of the present embodiment, as a type of winning combination, a small role accompanied by paying out medals, a re-playing role that does not require consumption of medals for the number of bets in the next game, and a transition of the gaming state. A special role is provided. The special role is accompanied by a transition of the gaming state and depends on the gaming state at that time, so it cannot be said to be a basic role. The playability of slot machines is not just playing a game, but the player earns medals based on the game results, so the small role that involves paying out medals by winning a prize is the most basic role. It can be said. Here, there are JAC, cherry, watermelon, and bell as types of small roles, but in addition to JAC that wins with a small probability in the regular bonus, it is determined as the types of winning combinations in any gaming state. ing. In this way, by defining the basic small combination as a winning combination regardless of the gaming state, the gameability becomes easy for the player to understand.

  When a big bonus is won in the normal gaming state, the gaming state is shifted to a big bonus that wins JACIN with a transition to a regular bonus with a relatively high probability (winning because there is no missing). The big bonus is ended when the total number of medals paid out to the player in the big bonus reaches 465 regardless of the number of digest games. Here, in a game with a big bonus (including a small role game and a regular bonus), since replay is not defined as a target character for internal lottery, no replay is won. Replay does not reduce the number of medals held by the player, but does not accompany the payout of medals, and therefore does not affect the number of payout medals, which is a condition for ending the big bonus. In other words, even if you make a replay win during the big bonus, it will only increase the number of big bonus games unnecessarily, so by not defining the replay as a target for internal lottery in the big bonus, The game can be efficiently advanced without unnecessarily prolonging the state.

  In addition, in the regular bonus game state, a small role (especially a bell) is won with a high probability and a large number of medals can be obtained, so the player has high expectations for this. This regular bonus is transferred not only when winning a JACIN in a small role game but also when winning a regular bonus in a normal gaming state. For this reason, even when the player is in the normal gaming state, the player can be given a sense of expectation for the regular bonus, so that the interest of the game can be improved. Furthermore, in the regular bonus, in addition to cherry, watermelon, and bell, which are defined in the normal gaming state and small role game, JAC is also defined as a small role. Thereby, the player's sense of expectation in the regular bonus can be further increased, and the interest of the game can be improved.

  In addition, the display mode of JACIN for shifting the game state from the small role game to the regular bonus in the big bonus is configured by a combination of “watermelon-JAC-JAC” and is not used as a display mode of other roles. It is. In the regular bonus, in addition to cherry, watermelon, and bell small roles, the JAC display mode is also determined by a combination of “Bell-JAC-JAC” and is not used as a display mode for other roles. It is. For this reason, the relationship between the display mode derived as the display result of the reels 2L, 2C, and 2R and the winning combination is clarified, and the gameability becomes easy for the player to understand.

  In addition, the rotation of the reels 2L, 2C, and 2R is stopped within the range of the maximum stop delay time of 190 milliseconds after the operation of the stop switches 8L, 8C, and 8R is detected. Since it can be pulled in, the symbol to be stopped can be selected from a range of five symbols. Here, the symbols “watermelon”, “bell”, and “JAC” are always arranged at intervals of 5 frames or less for each of the reels 2L, 2C, and 2R. Bell, Replay, JAC, and JACIN will not miss out when they are elected. In particular, the bells in the regular bonus will be won with a very high probability of approximately 1 / 1.03, but this will not be missed, so the player will effectively hold on to the regular bonus. It becomes unnecessary, and it becomes possible to advance the game easily.

  As described above, the types of winning combinations that are subject to internal lottery for each gaming state are registered in the winning combination table by gaming state, but the number of judgment values that determine the winning probability of each combination is referred to from the determining table. Stored in the address. In the role table, the number of medals when a winning of each role occurs is also registered.

  In the role-specific table, the number of medals is registered according to the number of wagers. When a winning of cherry, watermelon, or bell occurs, the number of medals is set according to the number of wagers (although for cherry and watermelon, the result is The same number of medals is set). Here, the bet number in the regular bonus is fixed at 1, but the bet number in the gaming state other than the regular bonus is fixed at 3. As a result, an appropriate number of medals can be paid out according to the gaming state simply by acquiring the payout number according to the number of bets. Further, since it is not necessary to determine the gaming state when setting the number of medals, the processing steps in the winning determination process are simplified. In addition, the number of bets 1 corresponding to the regular bonus has a higher number of medals at the time of winning the bell than the number 3 of bets, so the player's expectation in the regular bonus is further enhanced, and the interest of the game is enhanced. Can be improved.

  In the role-specific table, for cherry, watermelon, and bell defined as winning combinations in any gaming state, the storage address of the determination value number is registered for each bet number, and the determination value according to the bet number The number is acquired (although, in the case of cherry and watermelon, the same determination value number is acquired as a result). Here, the bet number in the regular bonus is fixed at 1, but the bet number in the gaming state other than the regular bonus is fixed at 3. Thereby, the internal lottery of cherry, watermelon, and bell can be performed with the winning probability corresponding to the gaming state only by acquiring the number of determination values according to the number of bets. In addition, since it is not necessary to determine the gaming state when acquiring the determination value number, the processing steps in the internal lottery are simplified. Moreover, since the bet number 1 corresponding to the regular bonus has a higher probability of winning the bell than when the bet number is 3, the player's expectation in the regular bonus is further increased, and the interest of the game is improved. Can do.

  In addition, the storage address of the judgment value number of each combination registered in the combination table may differ depending on the set value, but the winning probability is the same regardless of the set value. For the winning combination, the number of determination values is stored in common regardless of the set value. By storing the number of determination values in common in this way, the storage capacity required for that is reduced. However, in the role-specific table, even if the target number of the internal lottery is the same as the set bet number and the address storing the number of judgment values referenced according to the set value is different, it is stored at a different address. In some cases, the number of determination values is the same.

  In general, in the development stage, the simulation is performed while adjusting the number of determination values according to the set values for at least some of the combinations (that is, adjusting the winning probability of internal lottery). As the initial number of determination values, a different number of determination values is registered according to the set value. However, as a result of adjustment by simulation, the number of determination values when the set values are different may be the same. Although the same number of judgment values was registered as the initial number of judgment values according to the set value, the number of judgment values registered from the beginning may be used as it is depending on the result of simulation (result of simulation). The number of judgment values different from the initial value, that is, the number of judgment values may differ depending on the set value). Then, the number of determination values obtained with an appropriate result in the simulation in each case is selected as the number of determination values to be set for the mass production model.

  Here, even if the number of determination values adjusted by the simulation is the same regardless of the set value, the number of determination values is stored in the ROM 41b with the same address assignment as that in the development stage. It can be used as a model for mass production. For this reason, it is not necessary to change the method for storing the number of judgment values in the model for mass production from the model for development, so that development from the initial design stage to the model for mass production can be easily performed. Become.

  Further, the storage address of the judgment value number of each combination registered in the combination table is different depending on the number of bets (1 or 3), but is stored at different addresses such as cherry or watermelon, for example. In some cases, the same number of determination values is used.

  In the development model, it is normal to perform simulation while finely adjusting the judgment value data according to the number of bets (the same as when the initial number of judgment values is different) There may be cases). Here, even if the number of decision values adjusted by the simulation becomes the same regardless of the number of bets, the number of decision values is stored in the ROM 41b with the same address assignment as the address assignment in the development stage. It can be used as a model for mass production. For this reason, it is not necessary to change the method for storing the number of judgment values in the model for mass production from the model for development, so that development from the initial design stage to the model for mass production can be easily performed. Become.

  In addition, the internal lottery adds the number of judgment values of each role referred from the role-specific table to the acquired random number for internal lottery, and depending on whether or not the result of the addition overflows, Judgment is made on whether or not there is a win. For this reason, an internal lottery can be performed using the number of determination values of each combination as it is. In addition, when generating the winning determination table before the actual winning determination is performed, the loop processing is required twice. However, according to this embodiment, the loop processing in the lottery processing may be performed only once. Thus, the processing efficiency of the entire lottery process is high.

  Further, in the internal lottery in the normal gaming state, the lottery for the small combination and re-playing combination and the lottery for the special combination are separately performed based on the same random number for internal lottery. Then, after the special combination is established, that is, in a state where the special combination winning flag is carried over, only the small combination and the re-playing combination are drawn. For this reason, a plurality of special roles will not be won in duplicate. Furthermore, since the lottery for the small role and the re-playing role can be shared before and after the special role is established, the internal lottery in the normal gaming state can be simplified, and in the state where the special role is carried over after the special role is established. Since it is only necessary to perform the lottery of the small combination and the re-playing combination, the processing efficiency of the internal lottery in the state where the winning of the special combination is carried over becomes high.

  In the present embodiment, the lottery for the small role and replaying role and the lottery for the special role are separately performed based on the same random numbers for internal lottery. In the state where the winning flag is carried over, only the small role and the re-playing role are drawn, but even after the special role is established, If a special role is won by a special role lottery, the winning may be treated as invalid. Even in this case, multiple special roles may be won in duplicate. Absent.

  In addition, from the number of determination values stored in the address area registered in the role-specific table for the small role and the re-playing role and the number of determination values stored in the address area registered in the role-specific table for the special role It is possible to specify the range of judgment values for winning a small role, replaying role, and special role independently, and the range of judgment values for winning a small role and special role in duplicate. If the value obtained as a random number for internal lottery is included in the range of judgment values for each of the small role, replaying role, and special role specified by these judgment value numbers, It is determined that the re-playing role and the special role are each elected independently, and if both the small role and the special role are included in the range of judgment values to be won, both the small role and the special role are elected. It comes to judge. For this reason, if the value within the range in which the winning of both the special role and the small role is determined is obtained as a random number for internal lottery, the special role and the small role will be won at the same time. When the value of the range in which only the winning is determined is acquired as a random number for internal lottery, only the special combination or the small combination will be selected. As a result, even if a small role winning is generated as a result of the game, it is not denied that the occurrence of a special role having a higher advantage than the small role is allowed. A player's expectation can be maintained.

  In this embodiment, the number of judgment values stored in the address area registered in the role-specific table for the small role and the re-playing role and the address area registered in the role-specific table for the special role are stored. Based on the number of judgment values, it is possible to specify the range of judgment values for winning a small role, replaying role, and special role independently, and the range of judgment values for winning a small role and special role in duplicate. However, the number of judgment values stored in the address area registered in the role-specific table for the small role and the re-playing role and the judgment value stored in the address area registered in the role-specific table for the special role From the number, it may be possible to specify only the range of the judgment value that the re-playing role is won alone, and the range of the judgment value that the small role and the special role are won in duplicate. According to such a configuration, the game As a result of a small role winning as a result of Expected for that you have selected haves. In addition, from the number of determination values stored in the address area registered in the role-specific table for the small role and the re-playing role and the number of determination values stored in the address area registered in the role-specific table for the special role In addition, it may be possible to specify only the range of the judgment value that the re-playing role and the special role will be won alone, and the range of the judgment value that the small role and the special role will be won, and according to such a configuration, Even if the small role is not won as a result of the game, it is not denied that the special role is won, so the player's expectation for the special role can be maintained even in such a situation. In addition, from the number of determination values stored in the address area registered in the role-specific table for the small role and the re-playing role and the number of determination values stored in the address area registered in the role-specific table for the special role In addition, it may be possible to specify only a range of judgment values for winning a re-playing role and a small role alone, a range of judgment values for winning a small role and a special role, and according to such a configuration, Even if a small role wins as a result of the game, it is not denied that the special role has been won. Therefore, even in such a situation, the player's expectation for winning the special role can be maintained.

  Further, in this embodiment, the determination value for winning the big bonus (1) to (3) and the watermelon overlaps rather than the range of the determination value for winning the big bonus (1) to (3) and the cherry. The probability of winning the big bonuses (1) to (3) and watermelon at the same time is higher than the probability of winning the big bonuses (1) to (3) and cherry at the same time. Is higher. As a result, when the watermelon wins more than when the cherry wins, there is a higher possibility of winning at the same time as the big bonuses (1) to (3). Since the expectation of winning the big bonuses (1) to (3) can be changed depending on the type of the small role, the interest can be enhanced.

  In the present embodiment, the random number for internal lottery acquired by the random number acquisition process is not used as it is from the random number generation circuit 42 by the sampling circuit 43 but is used after being processed by software. Yes. The random number generation circuit 42 generates a random number by updating at a high speed at the frequency of the pulse signal of the pulse generation circuit 42a. However, in the random number for internal lottery after processing by software, the periodicity of the update is increased by the processing. It will be lost.

  On the other hand, in the internal lottery, since the number of determination values corresponding to each combination is sequentially added to the random value for internal lottery, each combination is determined to be a winning combination as shown in FIGS. The random number value for the internal lottery to be set will be hardened. On the other hand, it is possible to prevent the player from aiming as much as possible by losing the periodicity of the random numbers for internal lottery by processing by software and varying the values.

  Moreover, the frequency of the pulse signal generated by the pulse generation circuit 42a for updating the values of the counters 42b and 42c of the random number generation circuit 42 is higher than the frequency of the operation clock of the CPU 41a, and is not an integral multiple. For this reason, it becomes difficult for the update of the random number generated by the random number generation circuit 42 to be synchronized with the process performed by the CPU 41a. In addition, by increasing the frequency of the pulse signal of the pulse generation circuit 42a, the update speed of the random number generated by the random number generation circuit 42 can be made extremely fast.

  On the other hand, the processing of random numbers by software is performed by replacing the upper byte and lower byte of the random number extracted from the random number generation circuit 42 by the sampling circuit 43, masking the 15th and 7th bits, and then bit-shifting the upper byte. good. Therefore, even for a relatively large random number of 16 bits (actually masked 14 bits), the load required for processing necessary to lose periodicity is not so large, and can be easily obtained. Can do. Since a large random number can be acquired in this way, the probability setting in the internal lottery can be finely performed.

  Further, in the present embodiment, specific 2 bits (15th and 7th bits in this embodiment) are masked out of 2 bytes (16 bits) of random numbers extracted from the random number generation circuit 42 by the sampling circuit 43. A 14-bit random number is obtained. In general, a general-purpose random number generation circuit outputs a 16-bit random number. However, as a range of random numbers used in the internal lottery, a 14-bit random number is sufficient, and a 16-bit random number is used. If acquired as it is, the range of random numbers is too large, so the amount of data stored in the role-specific table increases, the storage area of the ROM 41b is compressed, and the numerical value to be processed in the internal lottery is also This is because the load on the CPU 41a also increases because it increases.

  As described above, in this embodiment, a 14-bit random number obtained by masking a specific 2-bit among 2-byte (16-bit) random numbers extracted from the random number generation circuit 42 by the sampling circuit 43 is acquired. Even if an inexpensive general-purpose random number generation circuit is used, the storage area of the ROM 41b is not compressed, and the load on the CPU 41a is not increased.

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

  For example, in the above-described embodiment, the determination value number storage area of the RAM 41c in which the determination value number used for the internal lottery is stored uses a 2-byte area to store the determination value number in each case. Of course, in a general slot machine, the number of judgment values for special roles is not often set to exceed 255 in any gaming situation. As described above, for those that do not need to set the number of determination values exceeding 255, the number of determination values may be stored using only a 1-byte area.

  Further, in the above-described embodiment, some of the determination values that are common regardless of the set value are stored in common for all of the set values 1 to 6, but the number of determination values is related to the set value. Even common items can be individually stored for each of the setting values 1 to 6. Further, if the number of determination values is common regardless of the set value, all of them can be stored in common for all of the set values 1 to 6.

  Moreover, in the said Example, it was whether it memorize | stored in common with the whole setting value 1-6, or it memorize | stored separately with respect to each of the setting values 1-6 in the said Example. However, it is assumed that the number of determination values is not stored in common for all of the setting values 1 to 6 (the common flag for the setting value is not set). About 4-6, the number of judgment values can also be made common. The same applies to the number of determination values for the bet number. For example, the bet numbers 1 and 2 may be common and the bet number 3 may be individual.

  In the above-described embodiment, the number of determination values referred to according to the number of bets for the same combination at the same set value is stored at a different address for each of the bets (1 or 3). That is, for the same combination at the same set value, even if the number of judgment values referred to according to the number of bets is the same, it is stored separately, but the combination with the same winning probability regardless of the number of bets For the role that makes the determination value number storage address common, or for the role that makes the winning probability the same regardless of the setting value and the number of bets, the address of the determination value number storage address is made common In this way, by storing the number of determination values in common, it is possible to reduce the storage capacity required for that purpose.

  In the embodiment, the number of determination values acquired according to the set value or the like is sequentially added to the random number value for internal lottery, but from the value of random number for internal lottery that acquired the acquired determination value number, Subtraction may be performed sequentially, and the result of the subtraction may be used as a new random value for internal lottery. When the number of determination values is subtracted from the random number value for internal lottery, the 15th and 14th bits of the random number for internal lottery are set to “0”, and the subtraction result overflows (here, the subtraction result is negative) It can be determined whether or not

  In the embodiment, in the internal lottery, the number of determination values of each combination according to the game situation is sequentially added to the acquired random number for internal lottery, and when the addition result overflows, the winning combination is won. It was supposed to be judged. On the other hand, a winning determination table in which a determination value for determining each combination as winning is determined for each game in accordance with the number of determination values for each combination according to the game situation, and the internal random number for internal lottery acquired It is good also as what performs an internal lottery by comparing this value with the determination value of each combination. In addition, a winning determination table in which determination values for determining each winning combination are stored in advance in the ROM 41b, and an internal lottery value is compared by comparing the acquired internal random number value with the determination value for each winning combination. It is also good to do

  Further, in the above embodiment, the game can be started only by setting 3 as the bet number in the small role game in the normal gaming state and the big bonus. On the other hand, even in the small game in the normal gaming state and the big bonus, it is possible to start the game by setting 1 as the bet number, and further, by setting 2 as the bet number, You may be able to get started. As a result, when 1 or 2 is set as the bet number in the small game in the normal gaming state and the big bonus, the winning probability of the small role in the internal lottery is lower than when 3 is set as the bet number. In both cases, the number of medals to be paid out when winning a small role can be increased. For example, when 3 is set as the bet number in the small game in the normal gaming state and the big bonus, the winning probability of the bell is 1 / 4.6 and the payout number is 8, but the bet number is 1 or 2 Is set, the winning probability of the bell may be 1 / 240.9 and the payout number may be 15. Further, the winning probability of the bell and the number of payouts may be changed when 1 is set as the bet number and when 2 is set.

  In the embodiment, in the internal lottery in the normal gaming state, for the same random number for internal lottery, the lottery of the small role and the replaying role referring to the role-specific table for the small role and the replaying role, and the special role The special role lottery that refers to the role-specific table is separately performed, and the number of judgment values stored in the address area registered in the role-specific table for the small role and the replay role and the special role Based on the number of judgment values stored in the address area registered in the role-specific table, the range of judgment values that each small role, replaying role, and special role win independently, and the small role and special role are won in duplicate. The range of judgment values to be specified can be specified, so that special roles and small roles can be won at the same time, but in the role table, the storage address of the number of judgment values corresponding only to special roles , Both special and small roles In the internal lottery, the storage address of the corresponding determination value number, the storage address of the determination value number corresponding only to the small role, and the storage address of the determination value number corresponding only to the replaying role are registered respectively. If the number of judgment values for each role referenced from the role table is added to the acquired random number for internal lottery, and the result of addition with the number of judgment values corresponding to only the special role overflows, the special role If the result of addition with the number of judgment values corresponding to both the special role and the small role overflows, the winning of both the special role and the small role is determined, and the small role or replay role If the result of addition with the number of decision values corresponding to only overflows, the winning combination of only the small role or replaying role is judged, so that the special role and the small role can be won simultaneously. You can also. In other words, it is possible to specify a range of judgment values for winning a small role, a replaying role, and a special role separately from a single role-specific table, and a range of judgment values for winning a small role and a special role in duplicate. By doing so, it is possible to adopt a configuration in which a special role and a small role can be won simultaneously.

  FIG. 51 is a diagram showing a modification of the role-specific table, and FIG. 52 is a flowchart showing a modification of the internal lottery process.

  The role-specific table shown in FIG. 51 includes big bonus (1), big bonus (2), big bonus (3), regular bonus (1), regular bonus (2), JACIN, JAC, cherry, big bonus (1 ) + Cherry, Big Bonus (2) + Cherry, Big Bonus (3) + Cherry, Watermelon, Big Bonus (1) + Watermelon, Big Bonus (2) + Watermelon, Big Bonus (3) + Watermelon, Bell, Replay The storage addresses for the number of judgment values are registered in the order in which they are referenced.

  The number of determination values for each combination is registered corresponding to the number of bets (BET) set by the player in the game. This is because even with the same combination, the winning probability in the regular bonus may differ from other combinations. In addition, the number of determination values according to the number of bets for each combination may be common regardless of the set value, or may be different depending on the set value. If the number of determination values is common regardless of the set value, a common flag is set (value is set to “1”).

  Big Bonus (1), Big Bonus (2), Big Bonus (3), Regular Bonus (1), Big Bonus (1) + Cherry, Big Bonus (2) + Cherry, Big Bonus (3) + Cherry, Big Bonus (1) + Watermelon, Big Bonus (2) + Watermelon, Big Bonus (3) + Watermelon is a role subject to internal lottery only in the normal gaming state, and a determination corresponding to the bet number 3 in the normal gaming state The storage address for the number of values is registered. Among these roles, the value of the common flag is 0 for the big bonus (1), the big bonus (2), the big bonus (3), and the regular bonus (1). The storage address for the number of judgment values is registered. Big Bonus (1) + Cherry, Big Bonus (2) + Cherry, Big Bonus (3) + Cherry, Big Bonus (1) + Watermelon, Big Bonus (2) + Watermelon, Big Bonus (3) + Watermelon The common flag value is 1, and the storage address of the common number of judgment values is registered regardless of the set value. Regular bonus (2) and JACIN are internal lottery targets only in the small bonus game in the big bonus, and the storage address of the number of judgment values corresponding to the bet number 3 in the small bonus game is registered. . The value of the common flag for this role is 1, and a storage address for a common number of determination values is registered regardless of the set value.

  The JAC is a role that is subject to internal lottery only with the regular bonus, and the storage address of the number of determination values corresponding to the bet number 1 with the regular bonus is registered. The common flag for this combination is 1, and a common storage address for the number of determination values is registered regardless of the set value. Replay is a role that is subject to internal lottery only in the normal gaming state, and a storage address for the number of determination values corresponding to the bet number 3 in the normal gaming state is registered. The common flag for this combination is 1, and a common storage address for the number of determination values is registered regardless of the set value.

  Cherry, bell, and watermelon are the targets for internal lottery in any gaming state, the storage address of the number of judgment values corresponding to the bet number 1 in the regular bonus, and in the normal gaming state or small role game A storage address of the number of determination values corresponding to the bet number 3 is registered. For cherry and watermelon, the common flag is 1, and a storage address for the common number of determination values is registered corresponding to the number of bets regardless of the set value. For the bell, the common flag is 0, and the storage address of the number of determination values is individually registered according to the set value corresponding to each bet number.

  Next, a modified example of the internal lottery process executed by the CPU 41a will be described based on the flowchart shown in FIG.

  In this internal lottery process, a random number acquisition process is performed (Sg101). In this random number acquisition process, a random number value for internal lottery is acquired based on the random number generated by the random number generation circuit 42.

  Then, the setting value stored in the RAM setting value work is read (Sg102), and whether or not the read setting value is in the range of 1 to 6, that is, whether the setting value stored in the setting value work is an appropriate value. If the read set value is not a value in the range of 1 to 6, an error code indicating a RAM abnormality is set in the RAM 41c (Sg104), and the process proceeds to the error process shown in FIG.

  If the setting value read in the step of Sg103 is in the range of 1 to 6, the combinations registered in the combination table of combinations in FIG. 51 are sequentially read in correspondence with the current gaming state (Sg105). The types of roles read here are regular bonus (regular bonus (1), regular bonus (2)), big bonus (big bonus (1), big bonus (2), big bonus (3) (+ cherry, + watermelon) Is not included))) (Sg106). If it is one of the regular bonus, big bonus, or JACIN, is the regular bonus or big bonus winning flag already set in the RAM 41c in the previous game, and has been carried over without winning based on the winning flag? It is determined whether or not (Sg107). If the read type of combination is neither a regular bonus nor a regular bonus, the process proceeds to Sg108.

  If the winning flag for the regular bonus or the big bonus has already been set, the process returns to the processing of Sg105, and further, the next registered role in the winning combination table by gaming state is read (regular bonus, big bonus and JACIN Is registered first in the role table, and this does not end the lottery process). Even if the type of the read combination is regular bonus, big bonus or JACIN, if neither the regular bonus winning flag nor the big bonus winning flag is set, the process proceeds to Sg108.

  In Sg108, the number of BETs set in step Sa2 is further read, and the common flag setting status is acquired from the role-specific table of FIG. 51 for the role and the role corresponding to the read BET number. As a result, it is determined whether or not a common flag is set for the combination and the BET number (Sg109).

  If the common flag is set, the determination value number stored in the address registered in the role-specific table of FIG. 51 for the role and the BET number is acquired (Sg110). Then, the process proceeds to Sg112. If the common flag is not set, the setting value set in the RAM 41c is read, and the determination stored in the address registered in the role-specific table corresponding to the setting value read for the role and the BET number The number of values is acquired (Sg111). Then, the process proceeds to Sg112.

  In the step of Sg112, the number of determination values acquired in the step of Sg110 or Sg111 is added to the random number value for internal lottery, and the result of the addition is used as a new random number value for internal lottery. Here, it is determined whether or not an overflow has occurred when the number of determination values is added to the random number for internal lottery (Sg113). If an overflow occurs, the winning combination is big bonus (1) + cherry, big bonus (2) + cherry, big bonus (3) + cherry, or big bonus (1) + watermelon, big bonus (2) + It is determined whether or not it is watermelon, big bonus (3) + watermelon (Sg114). Big Bonus (1) + Cherry, Big Bonus (2) + Cherry, Big Bonus (3) + Cherry, or Big Bonus (1) + Watermelon, Big Bonus (2) + Watermelon, Big Bonus (3) + If it is not a watermelon, the winning flag of the combination is set in the RAM 41c (Sg114). Then, the internal lottery process is terminated, and the process returns to the flowchart of FIG.

  In the step of Sg114, the combination is a big bonus (1) + cherry, big bonus (2) + cherry, big bonus (3) + cherry, or big bonus (1) + watermelon, big bonus (2) + watermelon, big If it is bonus (3) + watermelon, it is determined whether a regular bonus or a big bonus winning flag has already been set in the RAM 41c in the previous game and is carried over without winning based on the winning flag (Sg116). ). If neither the regular bonus winning flag nor the big bonus winning flag is set, the corresponding winning flag of the big bonus (1) to (3) and the winning flag of the cherry, or the corresponding of the big bonus (1) to (3) The winning flag and the watermelon winning flag are set in the RAM 41c (Sg117). Then, the internal lottery process is terminated, and the process returns to the flowchart of FIG.

  If the winning flag for the regular bonus or the big bonus has already been set in the step of Sg116, the winning flag for cherry or the winning flag for watermelon is set in the RAM 41c (Sg118). Then, the internal lottery process is terminated, and the process returns to the flowchart of FIG.

  If no overflow has occurred in the step of Sg113, it is determined whether there is a combination that has not yet been processed among the combinations determined for the gaming state (Sg119). If there is a combination that has not yet been processed, the process returns to Sg105, and the process continues with the next combination registered in the winning combination table by game state as the processing target. If there is no combination not to be processed, the internal lottery process is terminated and the process returns to the flowchart of FIG.

  As described above, according to the modification applied with the role-specific table shown in FIG. 51 and the internal lottery process shown in FIG. 52, the value of the range in which the winning of both the special role and the small role is determined is the value for the internal lottery. If it is acquired as a random number, the special role and the small role will be elected at the same time, and if the value of the range where only the special role is determined is acquired as a random number for internal lottery, only the special role Will be elected. As a result, even if a small role winning is generated as a result of the game, it is not denied that the occurrence of a special role having a higher advantage than the small role is allowed. A player's expectation can be maintained. In addition, since it is not necessary to register the number of judgment values corresponding to the special role lose, it is possible to save the capacity of the ROM 41b and to share the internal lottery process regardless of the gaming state, thereby simplifying the program. it can.

  Note that, in the above configuration, the range of determination values that each of the small combination, replay combination, and special combination wins independently from the number of determination values stored in the address area registered in the combination table shown in FIG. And a range of judgment values for winning a combination of small and special roles, but it is possible to replay from the number of judgment values stored in the address area registered in the role-specific table. It may be possible to specify only a range of judgment values for winning a combination, and a range of judgment values for winning a combination of small roles and special roles. If you win a prize, you can expect to be elected for a special role. Also, from the number of judgment values stored in the address area registered in the role-specific table, the range of judgment values that the re-playing part and special part win independently, the judgment value that the small part and special part wins redundantly However, according to such a configuration, even if a small role is not won as a result of the game, it is not denied that a special role is won. Even in the situation, the player's expectation for winning the special role can be maintained. In addition, from the number of judgment values stored in the address area registered in the role-specific table, the range of judgment values that the re-playing part and small part wins alone, the judgment value that the small part and special part wins in duplicate However, according to such a configuration, even if a small role wins as a result of the game, it is not denied that a special role is won. Can maintain the player's expectation of winning special roles.

  In the above configuration, after the special role is established, that is, in the state where the special role winning flag is carried over, the value of the determination value range in which the special role is won alone is acquired as a random number for internal lottery. If the value of the range of judgment values for winning a combination of small roles and special roles is acquired as a random number for internal lottery, it is determined that only the small role is won, Even if multiple special roles are not won, it will be lost even when the value of the judgment value range in which small and special roles are won in duplicate is acquired as a random number for internal lottery. Even in this case, a plurality of special roles will not be won in duplicate. In addition, after the special role is established, the role-specific table in which data that can specify the range of the judgment value that the special role wins alone and the judgment value range that the small role and the special role wins are not registered, In other words, the internal lottery process may be performed by the role-specific table in which only data that can specify the range of the determination value that the re-game player wins and data that can specify the range of the determination value that the small role wins are registered. Well, even in this case, multiple special roles will never win.

  In the above embodiment, the entire high-order byte of the random number extracted from the random number generation circuit 42 is replaced with the low-order byte, and the entire low-order byte is replaced with the high-order byte. On the other hand, the data of a specific bit among the random number bits extracted from the random number generation circuit 42 is simply replaced with data of other bits (however, other than the masked seventh and fifteenth bits). Also good. Alternatively, the random number value extracted from the random number generation circuit 42 may be directly acquired as a random number for internal lottery. Further, it may be processed into a random number for internal lottery by a method different from the above embodiment.

  FIG. 53 is an explanatory diagram of a first modification of the process until the CPU 41a processes the random number extracted from the random number generation circuit 42 into a random number for internal lottery by software. Also in the first modification, the random number extracted from the random number generation circuit 42 is stored in the 16-bit general-purpose register 41GR included in the CPU 41a.

  When the random number extracted from the random number generation circuit 42 is stored in the general-purpose register 41GR, the CPU 41a further extracts the value of the internal refresh register 41R as a processing random number. The CPU 41a adds the processing random number extracted from the refresh register 41R to the value of the upper byte of the general-purpose register 41GR (the value extracted from the upper counter 42c). The value of the lower byte of the general register 41GR (the value extracted from the lower counter 42b) is left as it is.

  Next, the CPU 41a performs an OR operation with the value of the general-purpose register 41GR, that is, a value obtained by adding a processing random number to the upper byte with 8080h. Furthermore, the CPU 41a shifts the upper 1 byte (8th bit to 15th bit) to the lower bit by bit, and inserts 1 into the empty 15th bit. The CPU 41a acquires the value stored in the general-purpose register 41GR at this time as a random number for internal lottery, and sequentially adds the number of determination values to this.

  FIG. 54 is an explanatory diagram of a second modification of the process until the CPU 41a processes the random number extracted from the random number generation circuit 42 into a random number for internal lottery by software. Also in this example, the random number extracted from the random number generation circuit 42 is stored in the 16-bit general-purpose register 41GR included in the CPU 41a.

  When the random number extracted from the random number generation circuit 42 is stored in the general-purpose register 41GR, the CPU 41a further extracts the value of the internal refresh register 41R as a processing random number. The CPU 41a adds the processing random number extracted from the refresh register 41R to the value of the upper byte of the general-purpose register 41GR (the value extracted from the upper counter 42c). The processing random number extracted from the refresh register 41R is also added to the lower byte value (the value extracted from the lower counter 42b) of the general-purpose register 41GR.

  Next, the CPU 41a performs a logical OR operation with the value of the general-purpose register 41GR, that is, the value obtained by adding the processing random numbers to the upper byte and the lower byte, respectively, with 8080h. Furthermore, the CPU 41a shifts the upper 1 byte (8th bit to 15th bit) to the lower bit by bit, and inserts 1 into the empty 15th bit. The CPU 41a acquires the value stored in the general-purpose register 41GR at this time as a random number for internal lottery, and sequentially adds the number of determination values to this.

  In the first and second modified examples described above, the value of the refresh register 41R is extracted as a random number for processing, and this is extracted from the high-order byte of the random number extracted from the random number generation circuit 42 (in the second modified example, further lower byte) ) To process random numbers. The random number processing applied here includes at least processing for adding a processing random number to the upper byte. Thereby, the variation of the random numbers for internal lottery can be increased, and the player can prevent the aiming as much as possible.

  Further, since the processing random numbers are extracted from the refresh register 41R, no special configuration is required as means for generating the processing random numbers. Moreover, the value of the refresh register 41R is updated every time the CPU 41a fetches an instruction, and the update interval is not constant. Therefore, a random number with high randomness can be extracted as a processing random number. And since the randomness of the processing random number is high, the randomness of the random number for internal lottery generated using the random number is also high.

  In the first and second modifications, the value extracted from the refresh register 41R is added to the upper byte (and the lower byte) of the random number extracted from the random number generation circuit 42. A value that is periodically updated by hardware or software may be added. Further, instead of adding a value extracted from the refresh register 41R (or a value replacing the refresh register 41R), a logical operation such as subtraction, logical sum, or logical product may be performed.

  Further, bit replacement such as replacement of the upper byte and the lower byte shown in the above embodiment may be used in combination with the first and second modifications. Also in the first and second modified examples, the interrupt to the CPU 41a is prevented in order to prevent the contents of the general-purpose register 41GR from being rewritten between the extraction of the random number from the random number generation circuit 42 and the end of the processing. It will be prohibited.

  Further, in the second modification, processing random numbers to be added to the upper and lower bytes of the random number extracted from the random number generation circuit 42 may be separately extracted from the refresh register 41R at different timings. Separately prepare the processing random number to be added to the upper byte and the processing random number to be updated to the lower byte. Means for extracting may be provided. In this case, one of the means for updating the processing random number for the upper byte and the means for updating the processing random number for the lower byte can be constituted by the refresh register 41R.

  In the above embodiment, the case where the present invention is applied to the case where the random number generated by the random number generation circuit 42, that is, the random number extracted by the hardware random number function is processed by software has been described. However, the random number processing by the software described above may be applied to random numbers that are periodically updated by software. For example, the CPU 41a sends an instruction to the second microcomputer to extract a random number periodically updated by a timer interrupt or the like in a second microcomputer different from the microcomputer constituting the main control unit 41, and I The data can be input to the CPU 41a via the / O port 41d and stored in the general-purpose register 41GR. The function of the second microcomputer may be included in the microcomputer that constitutes the main control unit 41. Also in this case, the random number value obtained after the processing can be varied, and the effect of preventing the player from aiming can be achieved.

  Further, in the above embodiment, after the game ends at the time of winning the big bonus, the game ends at the end of the big bonus when the stop function is disabled during the period until the production waiting time for the production at the BB winning time elapses. After that, after the ending waiting time elapses at the end of the big bonus when the stop function is set to be effective until the ending waiting time elapses, the store clerk performs a reset operation to release the stop state The setting of the bet number is prohibited during any of the above periods, but it is sufficient that the bet number setting is prohibited at least in any one or more of these periods.

  Further, although the slot machine 1 of the above embodiment is equipped with a stop function, it may be applied to a slot machine not equipped with a stop function.

  In the above embodiment, only the big bonus winning is applied as the special winning that the setting of the number of bets is prohibited for a certain period at the time of winning. However, other special winnings may be applied, and plural kinds of special winnings may be applied. It may be applied to winning.

  In the above embodiment, only the big bonus is applied as the special gaming state in which the setting of the bet amount is prohibited for a certain period at the end, but other special gaming states may be applied. You may apply to a special game state.

  In the above embodiment, the end of the game is determined by the end of the game end processing. However, the game is substantially ended by the end of the medal payout. The end may be determined. In other words, the credit can be settled from the end of the payout process.

  In the embodiment, when the CPU 41a initializes the RAM 41c, the initialization table of the ROM 41b is referred to, and the start address and initialization size corresponding to any of initializations 1 to 4 are determined according to the initialization conditions. Acquire, set the pointer to the start address, set the initialization size, clear the area of the corresponding address by 1 byte from the initialization address where the pointer was set, and initialize the size every time 1 byte is cleared 1 is subtracted and the process of advancing the pointer by 1 is executed until the initialization size becomes 0, so that the area of the RAM 41c corresponding to the initialization condition is initialized. The addressed area is set as a continuous address area, and the initialization table corresponds to one of initialization 1 to 4 depending on the initialization condition The start address and the end address common to all of initializations 1 to 4 are registered, and when the CPU 41a initializes the RAM 41c, the initialization table is referred to and the initialization address is initialized according to the initialization condition. The start address corresponding to any one of 1 to 4 is acquired, the pointer is set to the start address, and the area of the corresponding address is cleared to 0 by 1 byte from the initialization address to which the pointer is set, and 1 byte is cleared. Each time the pointer is advanced, the area of the RAM 41c corresponding to the initialization condition may be initialized by executing the process of advancing the pointer until the end address area common to the initializations 1 to 4 is cleared. .

  In this case, each time 1 byte is cleared, it is determined whether the address indicated by the pointer is the end address. If the address is the end address, the initialization may be terminated. The initialization byte number from the start address to the common end address is calculated and set, and every time 1 byte is cleared from the start address, the initialization byte number is decremented by 1 and the pointer is advanced by 1. It is preferable that the process is executed until the number reaches zero, and it is determined that the end address area has been cleared when the number of initialization bytes reaches zero, and the initialization is terminated. This is because the process of determining whether the number of initialization bytes is 0 is higher than the process of comparing the address indicated by the pointer and the end address for each byte.

  FIG. 55A is a diagram showing a modification of the storage area of the RAM 41c, FIG. 55B is a diagram showing a modification of the initialization table, and FIG. 56 is a modification of initialization 1. It is a flowchart to show.

  As shown in FIG. 55 (a), in this modification, the storage area of the RAM 41c is 7E00 (H), and the set value work, special work, important work, non-saved work, general work, unused area, unused The stack area is allocated in the order of the stack area in use. For this reason, even if any of initialization 1, 2, and 4 is performed, the initialized area becomes a continuous address area. Specifically, the areas initialized in the initialization 1 are all areas except the in-use stack area, that is, set value work, special work, important work, unsaved work, general work, unused area, unused stack. These areas are continuous address areas from 7E00 (H) to the stack pointer. The areas initialized in the initialization 2 are general work, unused area, and unused stack area, and these areas are continuous address areas from 7E53 (H) to the stack pointer. The areas initialized in the initialization 4 are an unused area and an unused stack area. These areas are continuous address areas from 7F05 (H) to the stack pointer. In initialization 2, general work, unused area, and unused stack area are initialized. In initialization 3, non-saved work, unused area, and unused stack area are initialized. The unused area and the unused stack area that are initialized in the initialization 3 are continuous address areas, but the non-saved work is a non-continuous address area.

  As shown in FIG. 55 (b), in the initialization table applied in this modification, start addresses are registered corresponding to initializations 1 to 4, and end addresses common to initializations 1 to 4. Is registered. In addition, since the initialization 3 is an address area where non-saved work is not continuous, the initialization size is registered corresponding to the start address of the non-saved work.

  Next, a modification of the initialization 1 executed by the CPU 41a will be described based on the flowchart shown in FIG.

  In this initialization 1, first, the initialization address in the ROM 41b is referred to, and the start address registered corresponding to the initialization 1 is read (Sm101). Then, a pointer is set to the read start address (7E00 (H)) (Sm102). Next, referring to the initialization table of the ROM 41b, the end address common to the initializations 1 to 4 is read (Sm103). Then, the number of bytes from the start address (7E00 (H)) read in Sm101 to the end address (stack pointer) read in Sm103 is calculated (Sm104), and the number of bytes in the area for initializing the calculated number of bytes is set. (Sm105). Then, a RAM clear process for clearing data from the start address set in Sm102 to the number of bytes set in Sm105 is executed (Sm106). When the RAM clear process is completed, the initialization 1 is completed. Return to.

  In addition, the modification example of initialization 2 and 4 is almost the same process as the modification example of initialization 1 shown in FIG. 56, and the start address of initialization 2 or initialization 4 registered in the initialization table is acquired. Then, the number of bytes from the start address to the common end address is calculated, and the data is cleared over the calculated number of bytes from the start address. In the modification of initialization 3, first, the start address and initialization size of the non-saved work registered in the initialization table are acquired, and after the data is cleared from the start address over the number of bytes corresponding to the initialization size, Get the start address of the unused area and unused stack area registered in the initialization table, calculate the number of bytes from the start address to the common end address, and clear the data over the calculated number of bytes from the start address Perform the process.

  According to the modification of the initialization of the RAM 41c as described above, for a plurality of initialization conditions, only the start address corresponding to the initialization table and the end address common to the plurality of initialization conditions are set. Because it is possible to initialize areas corresponding to multiple initialization conditions without individually setting end addresses corresponding to multiple initialization conditions, the program capacity for performing multiple types of initialization Can be reduced.

  In the embodiment, the RAM parity adjustment data is stored so that the RAM parity of the RAM 41c becomes 0 in the power interruption processing, and it is determined whether or not the RAM parity of the RAM 41c is 0 at the time of restoration. Although it is determined whether or not the data in the RAM 41c is normal, of course, the RAM parity adjustment data is stored so that the RAM parity of the RAM 41c becomes 1 in the power interruption processing, and the RAM parity of the RAM 41c becomes 1 at the time of restoration. Whether or not the data in the RAM 41c is normal may be determined. Further, the checksum (exclusive OR of the data stored in the corresponding area) of all areas of the RAM 41c is calculated in the power interruption processing, and is stored in a specific area, and at the time of recovery, the RAM 41c is restored. The checksum of all the areas including the specific area where the checksum is stored is calculated. If the result is 00 (H), it is determined that the data in the RAM 41c is normal, and must be 00 (H). For example, it may be determined that the data in the RAM 41c is abnormal.

  If the checksum is stored normally in the power interruption processing, the checksum of the area excluding the specific area and the data stored in the specific area (the checksum calculated at the time of power interruption) ) Should take the same value, and if the checksum of the area excluding the specific area matches the data stored in the specific area, the result of calculating the exclusive OR of both data is Since the result of calculating the checksum of all the areas including the specific area where the checksum of the RAM 41c is stored is 00 (H), it is determined that the data of the RAM 41c is normal. This is because it can.

  In this case as well, in the power interruption interrupt processing, before the checksum is calculated, the destructive diagnosis data (for example, 5A (H)) in which any bit is 1 is stored at a predetermined address, and at the time of restoration In addition to determining whether or not the checksum is 00 (H), it is also determined whether or not the data for destructive diagnosis is normally stored. The checksum is 00 (H) and the destructive diagnosis is performed. It is preferable to determine that the data in the RAM 41c is normal on the condition that the business data is also normal. Even if the data in the RAM 41c is not normal, if 00 (H) is stored in all areas, it will be determined to be normal by the checksum determination at the time of startup, After storing the destructive diagnostic data with the bit set to 1, calculate the checksum and store it in a specific area, and also check the destructive diagnostic data in addition to checking the checksum at startup, For example, even if all areas are cleared to 0 at startup, and the checksum is 00 (H) and determined to be normal, the destruction diagnosis data does not match the value stored at the time of power failure, Since the determination is made, it is possible to improve the accuracy of determining the abnormality of the data stored in the RAM 41c.

RAM parity or checksum of the RAM 41c is calculated and stored in a specific area, and the RAM parity or checksum excluding the specific area of the RAM 41c at the time of recovery is calculated, and the RAM parity or checksum stored in the specific area is calculated. The data in the RAM 41c depends on whether the comparison result matches It may be determined whether normal or not. In this case as well, as described above, before the RAM parity or checksum is calculated, the destructive diagnosis data in which any bit is 1 is stored at a predetermined address. In addition to determining whether or not the sums match, it is determined whether or not the data for destructive diagnosis is stored normally, the RAM parity and checksum match, and the destructive diagnostic data is also normal. It is preferable to determine that the data in the RAM 41c is normal under the above conditions.

  In the above-described embodiment, 5A (H) is stored in the RAM 41c as the failure diagnosis data in the power interruption processing. However, any data other than 0 may be stored and can be confirmed at the time of startup.

However, first, it is determined whether or not the data for destructive diagnosis is stored normally, and on condition that the data for destructive diagnosis is stored normally. The RAM parity of the RAM 41c may be calculated and it may be determined whether or not the result is 0. In this way, if the destructive diagnosis data is not normally stored, the RAM parity is calculated. Without calculation, it can be determined that the data in the RAM 41c is abnormal.

  In the embodiment, it is determined whether or not the data in the RAM 41c is normal only when the main control unit 41 is activated. However, the determination may be made every other opportunity, for example, for each game.

You may make it detect a power interruption, when the period when the said DC voltage became below a fixed voltage continued for a fixed period. Alternatively, the AC voltage supplied to the slot machine 1 may be monitored to detect a power interruption when a disturbance in the waveform of the AC voltage is detected, or when the period continues for a certain period.

  In the above embodiment, the power interruption detection circuit 48 is mounted on the game control board 40. However, the power interruption detection circuit 48 may be mounted in other places. For example, the game control board 40 may be connected to the power supply board 100 or the power supply board 100.
