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 (such as a CPU runaway), the memory In such a case, it is impossible to return to the original state, so that the storage state of the memory is initialized. Of course, since the setting value is also stored in the memory, it is impossible to restore the setting value that was originally set.

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

  Further, in recent years, there has been a fraudulent act of rewriting the setting value stored in the memory, that is, the setting value selected and set by the amusement store side to a setting value with a high payout rate by intentionally adding an improper radio wave or signal. Sometimes done. For this reason, when the set value is changed, the changed set value is also stored in a sub memory different from the memory storing the set value read when the internal lottery is performed, and applied to the internal lottery at the start of the game. There has been proposed a slot machine that compares a set value with a set value stored in a sub-memory, and outputs an error signal when both set values do not match, thereby interrupting the game processing ( For example, see Patent Document 3).

JP-A-6-114140 JP 2000-296200 A Japanese Patent Laid-Open No. 2005-6940

  In the slot machine described in Patent Document 3, since the setting value applied to the internal lottery is different from the setting value set by the game store side, how is an error signal output and the game process is interrupted? Although there is no particular description about whether to return, for example, as described in Patent Document 2, in the case where an error occurs, there is one that returns game processing by a reset operation by an employee of a game shop or the like. Since it is general, it is conceivable to restore in the same manner. That is, it is considered that after the preset set value is automatically set, the game process is returned by a reset operation by an amusement store employee or the like.

  However, because the setting value applied to the internal lottery is different from the setting value set by the game store, an error signal is output, and the game process is interrupted. Despite the interruption of the game process, the game process will be restored in the same simple procedure as the reset operation, that is, the normal error cancellation. There is a possibility that the error may be canceled by a person who has performed, and there is a possibility that such an illegal act cannot be sufficiently prevented.

  Furthermore, originally, an internal lottery should be performed by applying a winning probability based on a setting value selected and set by an operation on the amusement store side, and the occurrence of a prize should be allowed. When the reset operation is performed by an employee or the like, the game process is restored, and an internal lottery is performed by applying a winning probability based on a predetermined setting value automatically set by the control of the slot machine. Become. In other words, where the game should be played based on the setting value selected by the amusement store side, the game will be played based on the setting value automatically set by the slot machine. There was a problem that would be damaged.

  The present invention has been made paying attention to such problems, and an object of the present invention is to provide a slot machine capable of effectively preventing fraud and attaining a fair game.

In order to solve the above-described problem, a slot machine according to claim 1 of the present invention provides:
By setting a predetermined number of bets for one game, the game can be started, and a display result of a variable display device capable of variably displaying a plurality of types of identification information each identifiable can be derived. A slot machine in which one game is finished and a winning can be generated according to the display result of the variable display device,

Based on an operation of a predetermined setting operation means, a permissible stage selection means for selecting one of the permissible stages from a plurality of permissible stages having different ratios determined to permit the occurrence of winning,
An allowable stage setting means for setting data indicating the allowable stage selected by the allowable stage setting means in a storage area of the main data storage means;
Before the display result of the variable display device is derived, the data indicating the allowable level stored in the main data storage means is read, and a winning is generated at a rate corresponding to the allowable level indicated by the read data. Pre-determining means for determining whether or not to allow,
A permissible stage data judging means for judging whether or not the data indicating the permissible stage stored in the main data storage means for each game is appropriate data indicating the permissible stage selectable by the permissible stage selecting means; ,
Disabling means for disabling the progress of the game when it is determined by the allowable stage data determining means that the data indicating the allowable stage stored in the main data storage means is not appropriate data;
In a state where the progress of the game is disabled by the disabling means, the progress of the game is performed on the condition that the allowable stage is newly set by the allowable stage setting means based on the operation of the setting operation means. The disabling means for canceling the disabled state and allowing the game to proceed,
including,
It is characterized by that.
According to this feature, it is determined for each game whether or not the data indicating the allowable level that determines the rate at which the winning is allowed is appropriate, and if it is determined that the data indicating the allowable level is not appropriate. Game progress is disabled. That is, if the data indicating the allowable level is not appropriate data indicating the allowable level that can be selected by the allowable level selection means, the data indicating the allowable level may be illegally rewritten. Is disabled. The state in which the progress of the game is disabled is canceled by newly selecting and setting an allowable stage (setting value) based on the operation of the setting operation means. For this reason, in order to resume the game when there is a possibility that the data indicating the allowable level has been illegally rewritten, the operation of changing the allowable level is more time-consuming than the reset operation for canceling the normal error. Since it is necessary, such fraud can be effectively prevented.
Also, if there is a possibility that the data indicating the allowable stage has been illegally rewritten, the allowable stage selected and set based on the operation of the setting operation means, not the allowable stage automatically set by the slot machine The game is played based on (generally, the operation of the setting operation means is operated by an employee of the game shop, which is an allowable stage selected by the game shop side), so that the game is fair. be able to.
Note that the permissible stage data determination means may be configured so that the main stage is at least once at any timing of one game (for example, at the start or end of the game, or when a process that is always executed for each game). What is necessary is just to determine whether or not the data indicating the allowable level stored in the data storage means is appropriate data indicating the allowable level selectable by the allowable level selecting means.
In the first aspect of the invention, the permissible stage data determining means is an appropriate value indicating that the permissible stage data stored in the main data storage means for each game is selectable by the permissible stage selecting means. However, when the permissible stage data determination means satisfies a predetermined condition instead of every game (for example, a special game state advantageous to the player every predetermined number of games). It may be determined whether or not the data indicating the allowable level stored in the main data storage means is appropriate data indicating the allowable level that can be selected by the allowable level selection means. Even in this case, the same effect as that of the invention of claim 1 can be obtained.

The slot machine according to claim 2 of the present invention is
By setting a predetermined number of bets for one game, the game can be started, and a display result of a variable display device capable of variably displaying a plurality of types of identification information each identifiable can be derived. A slot machine in which one game is finished and a winning can be generated according to the display result of the variable display device,

including,
It is characterized by that.
According to this feature, when the allowable stage is changed, the data indicating the changed allowable stage is set in a plurality of different storage areas of the main data storage unit and stored in the plurality of different storage areas. It is determined for each game whether or not all the data indicating the permissible stages match, and if it is determined that any one does not match, the progress of the game is disabled. That is, normally, the data indicating the allowable stages stored in a plurality of different storage areas of the main data storage means should all match, and if even one of these data does not match, the data indicating the allowable stages illegally In this case, the progress of the game is disabled. The state in which the progress of the game is disabled is canceled by newly selecting and setting an allowable stage (setting value) based on the operation of the setting operation means. For this reason, in order to resume the game when there is a possibility that the data indicating the allowable level has been illegally rewritten, the operation of changing the allowable level is more time-consuming than the reset operation for canceling the normal error. Since it is necessary, such fraud can be effectively prevented.
Also, if there is a possibility that the data indicating the allowable stage has been illegally rewritten, the allowable stage selected and set based on the operation of the setting operation means, not the allowable stage automatically set by the slot machine The game is played based on (generally, the operation of the setting operation means is operated by an employee of the game shop, which is an allowable stage selected by the game shop side), so that the game is fair. be able to.
Note that the permissible stage data determination means may be configured so that the main stage is at least once at any timing of one game (for example, at the start or end of the game, or when a process that is always executed for each game). What is necessary is just to determine whether or not all the data indicating the allowable stages stored in a plurality of different storage areas of the data storage means match.
Further, in the invention of claim 2, the permissible stage data determining means determines whether or not all the data indicating the permissible stages stored in a plurality of different storage areas of the main data storage means match for each game. However, the main data storage is not performed when the permissible stage data determination means is not for each game but when a predetermined condition is satisfied (for example, for every predetermined number of games, except for a special game state advantageous to the player). It may be determined whether or not all the data indicating the allowable stages stored in a plurality of different storage areas of the means match. Even in this case, the same effect as in the invention of claim 2 can be obtained. can get.
According to a second aspect of the present invention, the permissible level data determining means determines whether or not all the data indicating the permissible levels stored in a plurality of different storage areas of the main data storage means match, and disables it. When the means determines that any one of the data indicating the allowable levels stored in a plurality of different storage areas of the main data storage means does not match by the allowable level data determining means, Although the progress is disabled, the allowable stage setting means sets the data indicating the allowable stage selected by the allowable stage setting means in three or more different storage areas of the main data storage means, and the allowable stage data The determination means has a predetermined number or more of the data indicating the allowable stages stored in three or more different storage areas of the main data storage means. Whether or not to match, and the disabling means is a predetermined number or more of the data indicating the allowable stages stored in three or more different storage areas of the main data storage means by the allowable stage data determining means The game progress may be disabled when it is determined that the data does not match, and even in this case, the same effect as the invention of claim 2 can be obtained, It is possible to prevent the progress of the game from being accidentally disabled just by missing some data.

Further, when the history allowable stage setting means determines whether or not the pre-decision means permits the occurrence of a prize in the second storage area of the main data storage means different from the first storage area. The timing for setting the data indicating the permissible stage read from the first storage area as the history is the data indicating the permissible stage when the pre-determining means determines whether or not to allow the occurrence of a prize. Any timing may be used as long as the game is finished after reading from the first storage area.
In addition, the permissible stage data determination means includes data indicating the permissible stage read from the first storage area for use by the prior determination means in the current game, and the previous time stored in the second storage area. Any data may be used as long as it determines whether or not the data indicating the permissible stage used by the predetermining means before the game matches, and the first determining means is used by the predetermining means in this game. Whether or not the data indicating the permissible level read from the storage area matches the data indicating the permissible level used by the pre-determining means in the previous game stored in the second storage area. Data indicating the permissible stage read from the first storage area for use in the current game and used by the pre-determining means, and a predetermined game stored in the second storage area. And data in the beam number before game shows the allowable step of the pre-determination means is used may be one that or determining whether the match.

Further, the permissible stage data determining means has data indicating the permissible stage read from the first storage area for use by the predetermining means in the current game, and the previous time stored in the second storage area. It may be determined whether or not the data indicating the permissible steps used by the pre-determining means in a plurality of games before the game matches. Further, in this case, the data indicating the permissible stage read from the first storage area for use by the predetermining means in the current game and the previous game stored in the second storage area Not limited to determining whether or not all the data indicating the permissible stages used by the pre-determining unit in a plurality of previous games match, but the pre-determining unit uses in the current game Data indicating the permissible stage read from the first storage area and each permissible stage used by the predetermining means in a plurality of games before the previous game stored in the second storage area. It is determined whether or not a predetermined number or more of the data shown matches, and the disabling means determines the prior decision in the current game by the allowable stage data determination means.

According to this feature, the judgment value data storage means stores judgment value data common to a plurality of types of allowable stages for any winning, and thus is common to a plurality of types of allowable stages. With respect to the winning in which the judgment value data is stored, the storage capacity necessary for storing the judgment value data can be reduced. That is, it is possible to reduce the data amount of the judgment value data necessary for determining whether or not winning is allowed.
Further, the determination value data storage means stores determination value data common to a plurality of types of allowable stages for any winning, and individually stores data corresponding to the types of allowable levels for other winnings. In this, the same number determination value data indicating the number of the same determination values is included as the determination value data individually stored according to the type of the allowable stage. Judgment value data determines the probability that the pre-determining means decides to allow each prize to occur according to the allowable stage, but for development models, this judgment value data is finely adjusted. In general, the simulation is performed (the initial judgment value data may be different or may be the same). Appropriate judgment value data obtained as a result of simulation is applied to a model for mass production. Here, even if the judgment value data becomes the same regardless of the allowable stage as a result of performing the simulation while changing the judgment value data in accordance with the allowable stage, such a type of winning is still in the allowable stage. The determination value data may be stored individually according to the type of the.
In addition, when the judgment value data is initially stored as the same number of judgment value data indicating the same judgment value individually according to the type of the permissible stage, the judgment value data that is initially registered according to the simulation result remains unchanged. If so, it can be stored in the determination value data storage means as it is as the same number of determination value data. When there is a problem with the judgment value data initially registered as a result of the simulation, the judgment value data can be changed in accordance with the allowable stage and stored in the judgment value data storage means as different number judgment value data. For this reason, since the storage mode of the judgment value data in the development model can be used as it is in the mass production model, development from the initial design stage to the mass production model can be easily performed.
Note that storing the judgment value data individually according to the types of allowable stages does not necessarily mean that the judgment value data is stored individually for the number of types of allowable stages. If the judgment value data is not stored in common, the data is included in this. For example, when there are six types of allowable stages (first stage to sixth stage), the determination value data is allowed in the case where the first to third stages are common and the fourth to sixth stages are common. Depending on the type, it is stored separately.
Further, the plurality of types of permissible steps that can be set by the permissible step setting means do not mean that the proportions at which the pre-decision means allow the generation of winnings must be different from each other in all types. It is only necessary that the permissible ratio in the types of the above is different from the permissible ratio in the other types. However, it does not preclude being different in all types.
Further, the judgment value data indicating the number of judgment values that are determined to be allowed to be generated by the predetermining means may be the number of judgment values themselves or define a range of judgment values. Thus, it may be data indicating the number of determination values.
Further, when the pre-determining means determines that it is allowed to simultaneously generate a plurality of types of winnings (for example, a special winning with a transition of a gaming state and a small winning with a game value), The determination value data storage means is not limited to storing the determination value data for each type of winning, but includes a plurality of cases where it is determined that the occurrence of any one type of winning is allowed independently. The judgment value data indicating the number of judgment values that will be determined to allow the occurrence of the types of winnings at the same time, and the judgment value that will determine to allow the occurrence of any type of winnings alone. The determination value data indicating the number may be stored separately.

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 generates an interrupt 3 every time the number of clock inputs reaches a certain number, that is, every certain time interval, and executes a timer interruption process described later. 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. 42) 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 for receiving a command transmitted from the main control unit 41 is executed. Further, the CPU 91a executes a timer interrupt process (sub) by generating an interrupt every time the number of clock inputs reaches a certain number, that is, every certain time 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 board 100, + 25V DC voltage, that is, the DC voltage serving as a source of generating + 24V, + 12V (VCC), + 12V, and + 5V DC voltage is shown in FIG. 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 +5 V 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

  Further, the CPU 41a executes a set value determination process for determining whether or not a set value used for the internal lottery in the internal lottery process described later is an appropriate value.

  In the set value determination process, the set value determination process 1 for determining whether or not the set value used for the internal lottery is within an appropriate range (1 to 6), the set value used for the internal lottery, and the setting set when the setting is changed Setting value determination processing 2 for determining whether or not the values match, whether or not the setting value used for the internal lottery of the current game and the setting value used for the internal lottery of the previous game match The set value determination process 3 to be determined is executed for each game.

  In the setting value determination process 1, when the setting value used for the internal lottery is not a value in the proper range, or in the setting value determination process 2, the setting value used for the internal lottery, the setting value set when the setting is changed, If the set values do not match or the set value used for the internal lottery of the current game does not match the set value used for the internal lottery of the previous game in the set value determination process 3, it is determined that the RAM is abnormal. The RAM abnormal error code is set and controlled to the RAM abnormal error state to disable the progress of the game. As described above, unlike the other error states, the RAM abnormal error state is not canceled even if the reset switch 23 or the reset / setting switch 38 is operated, and a new setting is made in the setting change mode described above. It will not be released until a value is set.

  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. The same values are registered in the addresses ADD + 10 and ADD + 12, ADD + 14 and ADD + 16, and ADD + 18 and ADD + 20, respectively. 5 and the set value 6 have the same bell win probability.

  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, 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 512-byte storage area. As shown in FIG. 12, addresses of 7E00 (H) to 7FFF (H) are assigned to each byte, as well as important work. , General work, special work, set value work 1 to 3, non-saved work, unused area, and 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 37-byte area from 7E8F (H) to 7EB3 (H), and data for transmitting a command to the effect control board 90, various software random numbers, and the like are initialized only before the setting is started. The work to be stored.

  The set value work 1 is a 1-byte area of 7EB4 (H), and is a work in which a set value used when performing lottery in the internal lottery process is stored. Before setting is started (before transition to the setting change mode) In the initialization of, 0 is stored, then it is corrected to 1, and the setting value newly set at the end of setting (at the end of the setting change mode) is stored.

  The set value work 2 is a 1-byte area of 7EB5 (H), and the set value read from the set value work 1 when the lottery is performed in the internal lottery process matches the set value stored at the end of the setting. This is a work for storing a setting value used when determining whether or not to perform the setting, and the setting value newly set at the end of the setting (at the end of the setting change mode) is stored.

  The set value work 3 is a 1-byte area of 7EB6 (H), and when the lottery is performed in the internal lottery process, the set value read out from the set value work 1 is selected in the internal lottery process of the previous game. This is a work that stores the setting value used when determining whether or not it matches the setting value used when performing, that is, the setting value of the previous game, and at the end of the setting (when the setting change mode ends) The set value newly set is stored and updated to the value read from the set value work 1 when the lottery is performed in the internal lottery process for each game.

  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. 13A, the CPU 41a of the main control unit 41 does not destroy the data in the RAM 41c before the start of setting (before the transition 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. 13B is a diagram showing 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. 12, the important work, the general work, the special work, the set value work 1 to 3, the non-saved work, the general work, the unused area, and the unused stack area are consecutive addresses from 7E00 (H). Since the total size of these areas is 1D3 (H) + M bytes, in initialization 1, 7D00 (H) to 1D3 (H) + M bytes are initialized. These areas are initialized in the order of important work, general work, special work, set value works 1 to 3, 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 general workpieces 7E28 (H) to 7E8E (H) is 67 (H) bytes. As shown in FIG. 12, 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. Then, as shown in FIG. 12, 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. 12, 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.

  In this embodiment, to initialize the storage area of the RAM 41c is to clear the data in the target area to 0, that is, to update the value of the target area to 0. The area data may be rewritten to a predetermined initial value.

  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 a 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. 15, 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 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 the storage area of the RAM 41c is initialized, all of the storage areas except the used stack area are initialized 1 (Sb4), and then the process proceeds to a loop process in which no process is performed. .

  If an error code other than a RAM error is set in step Sb3, it is determined whether an operation of the reset / setting switch 38 is detected (Sb5). If the operation is not detected, it is further determined whether or not the operation of the reset switch 23 is detected (Sb6). If the operation of the reset switch 23 is not detected, the process 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.

  When the operation of the reset / setting switch 38 is detected in the step of Sb5, or when the operation of the reset switch 23 is detected in the step of Sb6, the error code set in the RAM 41c is cleared (Sb7 ), The display state of the game auxiliary display 12 is returned to the display state saved in the stack in the step Sb1 (Sb8), and the process returns to the original process.

  As described above, in the error processing, if the error processing is other than the RAM 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. 14, if it is determined in step Sa9 that the data for destructive diagnosis is normal, the data in the RAM 41c is normal, so the non-saved work, the unused area, and the unused stack area in the RAM 41c are initialized. After performing initialization 3 (Sa11), the destruction diagnosis data is cleared (Sa12). Next, 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, an interrupt is permitted (Sa17), and the setting change process shown in FIG. 16, that is, the setting change mode is entered (Sa18). After the setting change process is completed, the game process is entered.

  In the setting change process, as shown in FIG. 16, the setting value stored in the setting value work 1 of the RAM 41c (the value of the setting value work 1 has been corrected to 1 before shifting to the setting changing process. Is 1) (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.

  Further, 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 all of the set value works 1 to 3 in the RAM 41c, and the set value is confirmed. After that (Sc7), the process waits 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.

  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 process due to the RAM abnormality error, the process proceeds to a loop process in which no process is performed, so that the progress of the game is disabled. If the data in the RAM 41c is not normal, 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. 17 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.

  18 and 19 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). If 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, and 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.

  20 to 22 are flowcharts showing the control contents of the internal lottery process executed by the CPU 41a in 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, each of the setting values stored in the setting value works 1 to 3 of the RAM 41c is read (Sg2), and the setting value used for the lottery based on the read setting value, that is, the setting value stored in the setting value work 1 A set value determination process for determining whether or not is appropriate is performed (Sg3). If the set value is appropriate in the set value determination process, the value stored in the set value work 3, that is, the set value used for the lottery in the previous game, is stored in the set value 1, that is, It is updated to the set value used for the lottery in this game (Sg4).

  Next, it is determined whether or not the current gaming state is the normal gaming state (Sg5). If the current gaming state is the normal gaming state, the winning combination table according to gaming state shown in FIG. 6A corresponds to the normal gaming state. The small combination and the re-playing combination are read in the order registered in (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 combination and the number of BETs are stored in the addresses registered in the combination table for the small combination and the replay combination corresponding to the set value read from the set value work 1 The number of determination values that are present is acquired (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 judgment values stored in the address registered in the special role role table corresponding to the setting value read from the setting value work 1 for the 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 winning combination is either lose-A or lose-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. 17 (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 address registered in the corresponding role table shown in FIGS. 6B and 6C corresponding to the set value read from the set value work 1 for the role and the BET number. The number of stored judgment 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, in the normal gaming state, the lottery for the same internal lottery and the re-playing role and the special role are separately drawn. In the state, a small combination (cherry and watermelon in this embodiment) and a special combination (in this embodiment, big bonuses (1) to (3)) that win the range of random numbers to be won simultaneously win. There is.

  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.

  Next, the set value determination process in the step of Sg3 will be described in detail based on the flowcharts of FIGS.

  In the set value determination process, as shown in FIG. 24, a set value determination process 1 (Sg51), a set value determination process 2 (Sg52), and a set value determination process 3 (Sg53) are sequentially executed.

  In the set value determination process 1 in the step of Sg51, as shown in FIG. 25, whether or not the value read from the set value work 1 is in the range of 1 to 6, that is, the set value used for the internal lottery of the current game is appropriate. It is determined whether or not the value is within the range (Sg61). If the value read from the set value work 1 is not within the range of 1 to 6, an error code indicating a RAM abnormality is set in the RAM 41c (Sg62), and FIG. If the value read from the set value work 1 is a value in the range of 1 to 6, the process proceeds to the set value determination process 2 in step Sg52.

  In the set value determination process 2 in the step of Sg52, as shown in FIG. 26, whether or not the value read from the set value work 1 and the value read from the set value work 2 match, that is, the current game. It is determined whether or not the set value used for the internal lottery matches the set value set at the previous setting change (Sg71), and the value read from the set value work 1 and read from the set value work 2 If the values do not match, an error code indicating RAM abnormality is set in the RAM 41c (Sg72), the process proceeds to the error processing shown in FIG. 15, and the values read from the set value work 1 and read from the set value work 2 If the value matches, the process proceeds to the set value determination process 3 in step Sg53.

  In the set value determination process 3 in the step of Sg53, as shown in FIG. 27, whether or not the value read from the set value work 1 and the value read from the set value work 3 match, that is, the current game. It is determined whether or not the set value used for the internal lottery matches the set value used for the internal lottery of the previous game (Sg81), and the value read from the set value work 1 and read from the set value work 3 If the two values do not match, an error code indicating a RAM abnormality is set in the RAM 41c (Sg82), the process proceeds to the error processing shown in FIG. 15, and the value read from the set value work 1 and the set value work 3 If the read value matches, the process returns to the flowchart shown in FIG.

  As described above, in the setting value determination process, whether or not the setting value used for the internal lottery of the current game is within an appropriate range, whether the setting value used for the internal lottery of the current game and the previous setting change By determining whether or not the set value matches, whether or not the set value used for the internal lottery of the current game and the set value used for the internal lottery of the previous game match, It is determined whether or not the setting value used for the internal lottery of the current game is an appropriate value, and if it is determined that the setting value is not an appropriate value in at least one of the determinations, the above-described RAM abnormality 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 activation, an error state due to a RAM abnormality error occurs and the game progresses. It is adapted to be functionalised.

  FIG. 28 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 is initialized. (Si9), after setting a value for measuring the production waiting time of the BB winning effect in the timer counter for the production waiting time provided in the special work of the RAM 41c (Si10), the process proceeds to Si11. Note that the value stored in the timer counter for the effect waiting time is subtracted every time a timer interrupt process described later is executed, and when the value stored in the timer counter for the effect waiting time becomes zero. It is determined that the production waiting time has elapsed.

  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. 29 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, a value for timing the effect waiting time of the ending effect is set in the timer counter for effect waiting time provided in the special work of the RAM 41c (Sj7), and then the RAM 41c. Clear the big bonus medium flag set to (Sj8) and the RAM 41c After the general work was initialized 2 to initialize in addition to use area and unused stack area (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.

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

  FIG. 30 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. 31 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. 32 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), the number of bytes (67 (H)) of the area to be initialized first is set (Sp4), and the RAM clear process for clearing data from the start address set in Sp3 over the number of bytes set in Sp4 (See FIG. 31) 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. 31) 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. 33 is a flowchart showing the control contents of initialization 3 executed when the CPU 41a has normal data in the RAM 41c in the startup process.

  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. 31) 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. 31) 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 is completed, the initialization 3 is completed. Return to the original process.

  FIG. 34 is a flowchart showing the control contents of initialization 4 executed by the CPU 41a for each game 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. 31) 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.

  FIG. 35 and FIG. 36 are flowcharts showing the control content of the timer interrupt process that is executed by the CPU 41a 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 Ss16, 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. 37 shows the control contents of the interruption interrupt process executed by the CPU 41a in response to the occurrence of the interruption 2, that is, when the voltage drop signal from the interruption detection circuit 48 is input, interrupting the execution process or the game process. 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.

  As described above, in the slot machine 1 of the present embodiment, whether or not the value read from the set value work 1 is in the range of 1 to 6, that is, whether or not the set value used for the internal lottery is in the proper range. The set value determination process 1 to be determined is executed for each game, and if the value read from the set value work 1 is not a value in the range of 1 to 6, it is controlled to an error state due to a RAM abnormality error, and the game cannot proceed. It becomes. In this embodiment, the value stored in the set value work 1, that is, the range of the set value that can be selected by the setting change process is a value of 1 to 6, and therefore the value stored in the set value work 1 is 1 to 6. If the value is not in the range, there is a possibility that the set value has been illegally rewritten. In this case, the progress of the game is disabled.

  Also, whether the value read from the set value work 1 and the value read from the set value work 2 match, that is, the set value used for the internal lottery matches the set value set when the setting is changed. Even if the set value determination process 2 for determining whether or not to perform is executed for each game and the value read from the set value work 1 does not match the value read from the set value work 2 It is controlled to the error state by and game progress is disabled. In this embodiment, when the setting is changed, the setting value after the change is stored in each of the setting value work 1 and the setting value work 2, and normally, the value stored in the setting value 1 and the setting value 2 are stored. The values stored in the should match, and if these values do not match, the setting value may have been rewritten illegally, and in this case, the progress of the game is disabled. Become.

  In addition, whether the value read from the set value work 1 and the value read from the set value work 3 match, that is, the set value used for the internal lottery of the current game and the internal lottery of the previous game. The set value determination process 3 for determining whether or not the set value matches the set value is executed for each game, and the value read from the set value work 1 does not match the value read from the set value work 3 Even in this case, the game is controlled to an error state due to a RAM abnormality error, and the progress of the game is disabled. In this embodiment, the set value used for the internal lottery is stored in the set value work 3, and normally the value stored in the set value 1 (the set value used in the internal lottery of the current game) and The value stored in the setting value 3 (the setting value used in the internal lottery of the previous game) should match, and if these values do not match, the setting value may have been illegally rewritten. In this case, the progress of the game is disabled.

  Then, once controlled to an error state due to a RAM abnormality error, the game cannot be progressed unless the setting change mode is entered and a setting value is newly selected and set based on the setting changing operation. Is not released. In other words, in order to restart the game when there is a possibility that the setting value has been illegally rewritten, it is necessary to perform a setting change operation that is more time-consuming than the reset operation for canceling the normal error state. Cheating can be effectively prevented.

  If there is a possibility that the setting value has been rewritten illegally, 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, Since the setting change operation is performed by an employee of the game store, it is ensured that the game is played based on the setting value selected by the game store side), so that the fairness of the game can be achieved.

  In this embodiment, six values in the range of 1 to 6 are applied as set values used for internal lottery, that is, set values that determine the winning probability of internal lottery. However, the set values are limited to this. Any setting value can be used as long as it can select and set at least a plurality of setting values. For example, a setting value that can select two levels of high / low and a setting value of three levels in the range of 1 to 3 can be selected. Selectable setting values may be applied. Further, although the values 1 to 6 themselves are stored in the set value works 1 to 3 of the RAM 41c as values indicating the set values, any value that can specify the set value may be stored. For example, 0 to 5 (a value obtained by subtracting 1 from the actual set value) corresponding to the set values 1 to 6 may be stored in the set value works 1 to 3.

  Further, in this embodiment, the setting value determination process 1 for determining whether or not the value read from the setting value work 1 is in the range of 1 to 6, the value read from the setting value work 1, and the reading from the setting value work 2 Set value determination processing 2 for determining whether or not the values match, set value determination for determining whether or not the value read from the set value work 1 and the value read from the set value work 3 match All of the processing 3 is executed to determine whether or not the setting value used for the internal lottery is appropriate. However, by performing any one of these setting value determination processing 1 to 3, the internal lottery For example, it is possible to determine whether or not the set value to be used is appropriate. For example, only the set value determination process 1, only the set value determination process 2, or only the set value determination process 3 is performed. Any one of the set value determination processes 1 to 3 to be performed To perform the processing, or the like may be used.

  Further, any one of the set value determination processes 1 to 3 is performed for each game, and the remaining one process or all the remaining processes are performed at a predetermined opportunity (for example, every predetermined number of games, at the end of the bonus, Or two of the set value determination processes may be performed for each game, and the remaining one process may be performed at a predetermined opportunity.

  In this embodiment, the set value determination processes 1 to 3 are executed for each game. However, the set value determination processes 1 to 3 are not performed for each game, but the set value determination processes 1 to 3 are performed for a predetermined number of games. It may be performed every time or in a game of a specific period (such as a period excluding bonus).

  In this embodiment, in the internal lottery process, the set value determination processes 1 to 3 for determining whether or not the set value used for the internal lottery is appropriate are executed. Any timing may be used, for example, it may be performed at the start of the game or at the end of the game.

  In the present embodiment, in the internal lottery process, the value of the set value work 3 is updated to the value read from the set value work 1 (the set value read for use in the internal lottery of the current game). The timing at which the value of the set value work 3 is updated to the value read from the set value work 1 is any timing until the game ends (for example, when all the reels 2L, 2C, 2R are stopped, Etc.) at the time of withdrawal.

  In the present embodiment, when the setting is changed, the set value is stored in two areas of the set value work 1 and the set value work 2. In the set value determination process 2, the value stored in the set value work 1 and the setting are stored. It is determined whether or not the value stored in the value work 2 matches, and if it does not match, it is determined that it is not an appropriate setting value, but the setting value is stored in three or more storage areas when the setting is changed. In the set value determination process 2, it is determined whether or not all the values stored in these three or more storage areas match, and if they do not match, it is determined that the set value is not an appropriate setting value. Also good.

  Further, at the time of setting change, setting values are stored in three or more storage areas, and in the setting value determination process 2, whether or not the values stored in these three or more areas match a predetermined number or more (for example, 5 Setting values are stored in one storage area, and it is determined whether or not three or more of the values match, and if a predetermined number or more does not match, it may be determined that the setting values are not appropriate. In this way, even if a part of the data indicating the setting value stored at the time of setting change is lost due to noise or the like, it is erroneously determined that the setting value is not appropriate and the progress of the game is disabled. Can be prevented.

  In the present embodiment, only the set value used for the internal lottery of the previous game is stored in the set value work 3. In the set value determination process 3, the value stored in the set value work 1 and the set value work 3 are stored. Whether the set value used for the internal lottery of the current game matches the set value used for the internal lottery of the previous game is the same If not, it is determined that the setting value is not appropriate, but the setting value used for the internal lottery of each game is stored for a predetermined number of games before the previous game, and the setting value determination processing 3 It is determined whether or not the setting value used for the lottery matches the setting value used for the internal lottery of the game before the previous game (for example, a game before a predetermined number of games). Appropriate set value It may be determined that there is no.

  Further, the setting values used for the internal lottery of each game are stored over a predetermined number of games before the previous game, and the setting values used for the internal lottery of the current game in the setting value determination process 3 and a plurality of values before the previous game are stored. It may be determined whether or not all the set values used in the internal lottery of the game match, and if they do not match, it may be determined that the set values are not appropriate.

  Furthermore, the set values used for the internal lottery of each game are stored for a predetermined number of games before the previous game, and the set values used for the internal lottery of the current game in the set value determination process 3 and a plurality of values before the previous game are stored. Whether or not each set value used for the internal lottery of the game matches a predetermined number or more (for example, each set value used for the internal lottery of the past 5 games is stored in five storage areas, of which 3 If two or more values do not match, it may be determined that the set value is not an appropriate setting value. In this case, the setting is changed due to noise or the like. Even when a part of the data indicating the set value stored sometimes is missing, it is possible to prevent the game from being disabled due to erroneous determination that it is not an appropriate set value.

  Further, 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 even if an unauthorized program is stored using the unused area of the RAM 41c, It is possible to prevent unauthorized programs 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 unused area and the unused stack area of the RAM 41c are initialized for each game. However, at least one of the unused area and the unused stack area of the RAM 41c is initialized for each game. Anything that can be initialized is acceptable.

  Further, in this embodiment, by executing initialization 4 for initializing the unused area and the unused stack area of the RAM 41c at the end of the game, the unused area and the unused stack area of the RAM 41c are set for each game. If the unused area and / or the unused stack area of the RAM 41c is initialized at least once per game, 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 in 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, when it is determined that the data stored in the RAM 41c is not normal and a RAM abnormal error state occurs, initialization 1 is performed to initialize all areas except the used stack area of the RAM 41c. Even when it is determined that the data stored in the RAM 41c is not normal, and when the setting key switch 37 is turned on after that, all the areas except the used stack area of the RAM 41c Since the initialization 1 is performed, the malicious program that may be stored in the RAM 41c can be surely removed.

  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 due to the RAM abnormality error once. If it is controlled, the state in which the progress of the game is disabled is not released unless the setting change mode is entered and the setting value is newly selected and set based on the setting changing operation. That is, even when an abnormality occurs in the data stored in the RAM 41c, the game is not based on the setting value automatically set by the slot machine but based on the setting value selected / set based on the setting change operation. Since it is guaranteed to be performed, 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 the present embodiment, in the power interruption interrupt processing, destruction diagnosis data (in this embodiment, 5A (H)) in which one of the bits is 1, that is, specific data other than 0 is stored in the RAM 41c according to a predetermined data. After storing in the address, adjustment data is stored so that the RAM parity based on all the data of the RAM 41c including the destructive diagnosis data becomes 0. In addition to determining whether or not the RAM parity is 0 at the start, the destruction It is determined whether or not the diagnostic data is stored normally, and it is determined that the data in the RAM 41c is normal on the condition that the RAM parity is 0 and the destructive diagnostic data is also stored normally. 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. Data is cleared (updated to 0), so that the data for destruction diagnosis remains stored in the RAM 41c even after startup, so that the data in the RAM 41c is not normal at the next startup. Nevertheless, it is possible to prevent erroneous determination that the data is normal because the diagnostic data is stored.

  Further, in this embodiment, when an abnormality occurs in the data of the RAM 41c and the progress of the game is disabled, the mode is changed to a setting change mode (setting change process) in which the setting value changing operation is valid. At the same time, all the areas except the stack area in use of the RAM 41c are initialized. Therefore, the data initialization associated with the abnormality of the data in the RAM 41c and the data initialization associated with the selection / setting of the set value are performed. This can be performed once, and wasteful 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 or not 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 setting change mode is entered, and a new setting value is selected and set. 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, 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.

  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 embodiment, when the CPU 41a initializes the RAM 41c, the initialization table of the ROM 41b is referred to, and the start address and the initialization size corresponding to any of initializations 1 to 4 according to the initialization condition. , Set the pointer to the start address, set the initialization size, clear the corresponding address area to 1 byte at a time from the initialization address where the pointer is set, and initialize each time 1 byte is cleared The area of the RAM 41c corresponding to the initialization condition is initialized by executing the process of decrementing the size by 1 and advancing the pointer by 1 until the initialization size becomes 0. The area to be initialized is set as a continuous address area, and the initialization table contains one of initializations 1 to 4 according to the initialization condition. A corresponding start address and an end address common to all initializations 1 to 4 are registered, and when the CPU 41a initializes the RAM 41c, the initialization table is referred to according to the initialization condition. The start address corresponding to one of initializations 1 to 4 is acquired, a pointer is set to the start address, and the area of the corresponding address is cleared to 0 for each byte from the initialization address where the pointer is set, and 1 byte The process of advancing the pointer each time it is cleared is executed until the area of the end address common to the initializations 1 to 4 is cleared, so that the area of the RAM 41c corresponding to the initialization condition is initialized. good.

  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. 38A is a diagram showing a modification of the storage area of the RAM 41c, FIG. 38B is a diagram showing a modification of the initialization table, and FIG. 39 is a modification of initialization 1. It is a flowchart to show.

  As shown in FIG. 38A, in this modification, the storage area of the RAM 41c is set to 7E00 (H), the set value works 1 to 3, special work, important work, non-saved work, general work, unused area. The unused stack area and the used stack area are allocated in this order. 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 excluding the in-use stack area, that is, setting value works 1 to 3, special work, important work, unsaved work, general work, unused area, These are unused stack areas, and 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. 38 (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. 39, 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.

  In the above, the RAM parity or checksum of the RAM 41c is calculated in the power interruption processing and stored in the RAM 41c, and whether or not the RAM parity calculated based on all areas of the RAM 41c at the time of restoration is 0. Or whether the data in the RAM 41c is normal based on whether or not the checksum calculated based on all the areas of the RAM 41c is 00 (H). 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.

  Moreover, in the said Example, although 5A (H) is stored in RAM41c as destruction diagnosis data in a power interruption interruption process, as long as data other than 0 can be stored and can be confirmed at the time of starting, Even in such a configuration, if all the areas are cleared to 0 at startup, the destruction diagnosis data does not match the value stored at the time of a power failure and is determined to be abnormal, so it is stored in the RAM 41c. This makes it possible to improve the accuracy of determining abnormalities in the data being processed.

  In the above embodiment, when the CPU 41a is started, the RAM parity of the RAM 41c is calculated, it is determined whether or not the result is 0, and the destructive diagnosis data is normal on the condition that the RAM parity is 0. 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.

  In the embodiment, the main control unit 41 is activated based on a reset signal from a reset circuit 49 provided separately from the main control unit 41. However, the reset circuit is connected to the main control unit 41. The microcomputer which comprises may be mounted.

  In the above-described embodiment, the RAM 41c is mounted on the microcomputer constituting the main control unit 41. However, a RAM used as a work of the microcomputer may be mounted outside the microcomputer.

  In the embodiment, the power interruption detection circuit 48 monitors the DC voltage used in the slot machine 1 and detects the power interruption when the DC voltage becomes a certain voltage or lower. 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. It may be mounted on a relay board or the like through which a power supply line is connected.

  Moreover, in the said Example, the error is alert | reported by displaying on the game auxiliary | assistance display 12 the error code according to the error state about the content of various error states. In other words, the notification means controlled by the game control unit 41 is notified, but in addition to the notification means controlled by the game control unit 41, a command indicating an error state is transmitted to the effect control unit 91, The notification means controlled by the control section 91 may notify the error, or the notification means controlled by the game control section 41 does not perform the notification, but the notification means controlled by the effect control section 91 does not. An error notification may be performed.

  Moreover, in the said Example, the determination value number storage area | region of RAM41c in which the determination value number used for an internal lottery is memorize | stored shall memorize | store the determination value number in each case using a 2 byte area | region. 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. 40 is a diagram showing a modification of the role-specific table, and FIG. 41 is a flowchart showing a modification of the internal lottery process.

  The role-specific table shown in FIG. 40 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, based on the flowchart shown in FIG. 41, the modified example of the internal lottery process which CPU41a performs is demonstrated.

  In the internal lottery process in this modification, first, a random number acquisition process, which will be described later in detail, is performed (Sg101). 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 setting values stored in the setting values work 1 to 3 of the RAM 41c are read out (Sg102), and the setting values used for the lottery based on the read setting values, that is, the setting values stored in the setting value work 1 A set value determination process for determining whether or not is appropriate is performed (Sg103). If the set value is appropriate in the set value determination process, the value stored in the set value work 3, that is, the set value used for the lottery in the previous game, is the value stored in the set value 1, that is, The setting value used for the lottery in the current game is updated (Sg104).

  Next, in accordance with the current gaming state, the combinations registered in the combination table of combinations in FIG. 40 are read in order (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 Sd1 is further read, and the common flag setting status is acquired from the role-specific table in FIG. 40 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. 40 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 table to which the role-specific table shown in FIG. 40 and the internal lottery process shown in FIG. If it is acquired as a random number, the special role and the small role will be elected at the same time. 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. 42 is an explanatory diagram of a first modification of the processing 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. 43 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.

  In the embodiment, the slot machine for setting bets using medals and credits is used. However, the present invention is not limited to this, and the slot machine for setting bets using game balls. Alternatively, it may be a complete credit type slot machine that uses only credits to set the number of bets.

  Each element in the embodiment corresponds to the present invention as follows.

The slot machine according to claim 1 of the present invention includes:
A game can be started by setting a predetermined number (1 or 3) of bets for one game using a game value (medal), and a plurality of types of identification information (designs) that can be distinguished from each other The display result of the variable display device (reels 2L, 2C, 2R) capable of variably displaying the game is derived and displayed, so that one game is completed and a slot can be generated according to the display result of the variable display device. Machine (slot machine 1),
It has main control means (main control unit 41) for controlling the game,
The main control means includes
