Description

  The present invention relates to a slot machine capable of setting a bet number using a game medium such as a pachinko ball or a medal that can be used for a game and playing a game by setting the bet number.

  Conventionally, in gaming machines represented by this type of slot machine, for example, game state information relating to the control state of a game that has already been performed, for example, the number of fluctuations or the number of jackpots is counted and stored in a storage means. There are some which can calculate a payout rate, a jackpot probability, etc. from the game history information stored in the storage means, and are provided with a display switch for displaying these game history information on a predetermined display device, etc. (For example, refer to Patent Document 1).

  In addition, the game history information is stored and held in the same manner as the gaming machine described in Patent Document 1, and it is possible to execute the optimal game control for the gaming machine based on the gaming history information. In order to prevent the accumulation amount from becoming excessive, there is one provided with a data clear switch for initializing the game history information (see, for example, Patent Document 2).

  By the way, this type of slot machine performs an internal lottery to determine whether or not to allow a prize to be generated almost simultaneously with the start of the game, and the winning of the winning prize is allowed on condition that the internal lottery is won. 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.

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

  For this reason, in the conventional slot machine, when an abnormality occurs in the memory data, the memory data is initialized, and the set value includes a predetermined set value (for example, a winning probability with a payout rate close to 100%). And a setting value that determines the winning probability at which the payout rate is the lowest) are automatically set to return to a state in which the game can proceed (see, for example, Patent Documents 3 and 4).

JP-A-7-51460 (page 3-4, FIG. 1) JP 2002-35359 A (page 7, FIG. 3) JP-A-6-114140 JP 2000-296200 A

  However, the display switch in the gaming machine described in Patent Document 1 is provided in a state in which the player can operate, so that the player can display and view the game history information, and described in Patent Document 2 above. When the data clear switch in the gaming machine is provided in a state that can be operated by the player, there is a possibility that the player may operate the data clear switch without permission to initialize the game history information, If it has been initialized, there is a problem that only a short-term game history is displayed when another player tries to view the game history of the gaming machine.

  In addition, in the conventional slot machines described in Patent Documents 3 and 4, when an abnormality occurs in the data in the memory, the set value is selected and set by an operation of an amusement shop employee or the like as described above. Since the preset setting value is automatically set instead of the set value, and the game is restored to the state in which the game can proceed, it was originally selected and set by the operation of the amusement store. An internal lottery is performed by applying the winning probability based on the set value, and the occurrence of a prize should be allowed, but if an error occurs in the memory data, it is automatically set in advance by the control of the slot machine. An internal lottery will be performed by applying the winning probability based on the set value that has been determined. In other words, the game should be played based on the setting value automatically set by the slot machine due to a malfunction of the slot machine, where the game should be played based on the setting value selected by the game shop side. There was a problem that the fairness of the game was lost.

  The present invention has been made paying attention to such problems, and effectively eliminates the problem that a player can initialize a game history without permission and other players can view only a short-term game history. It is an object of the present invention to provide a slot machine that not only can be suppressed, but also can effectively prevent fraud and achieve fairness of the game.

According to this feature, the game history initialization process for initializing the game history information stored in the game history storage means is an initial setting operation provided at a position where the player cannot perform an operation when the power is turned on. When the display operation unit is operated in the game history initialization enabled state, which is controlled when the production control means determines that it is controlled to the initial setting state that is not controlled unless the unit is operated Therefore, it is possible to effectively prevent the player from initializing the game history information and causing other players to view only short-term game history information. In addition, the game history information can be initialized together with the initialization of the data for controlling the game when power supply is started, as well as for display used when browsing the game history information. Since the operation unit is used, it is possible to reduce the time and effort of the initialization process.
In addition, it is determined for each game whether or not the set value data indicating the set value that determines the rate at which winning is allowed is appropriate. If it is determined that the set value data is not appropriate, the game progresses. It is disabled. That is, if the set value data is not appropriate data, there is a possibility that the data indicating the set value has been illegally rewritten. 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 a set value. For this reason, in order to restart the game when there is a possibility that the data indicating the set value has been illegally rewritten, the setting value change operation is more time-consuming than the reset operation for canceling the normal error. Since it is necessary, such fraud can be effectively prevented.
If there is a possibility that the set value data has been illegally rewritten, the set value selected / set based on a predetermined setting operation (predetermined value) is not set automatically by the slot machine. The setting operation can be performed in the initial setting state, that is, the game is performed based on the setting value selected by the amusement store side because it is operated by an amusement store employee or the like. Can be fair.
Further, the game control means outputs the initial setting state without outputting the information indicating that the game state return process is executed and the information indicating that the control of the initial setting state is executed as separate control information to the effect control means. It is only necessary to output control information (initial setting state specifying information) indicating that the control load is reduced by reducing the type of control information output to the production control means, and the storage area for the control information is also reduced. It can be reduced as much as possible.
Note that the predetermined number of bets is at least one bet number, and a game can be started by setting a bet number of two or more or setting a maximum bet number. good.
Further, the information related to the game result is information related to the result obtained by playing the game.For example, as a result of the internal lottery performed for each game, whether or not a winning has occurred, the type of winning that has occurred, the gaming state The information shown is included.

In addition, the game history initialization enable state control means is a game history initializing means capable of initializing the game history information when it is determined by the initial setting state determination means that the game history information is controlled to the initial setting state. Although it was supposed to be controlled to enable state,
The game history initialization enable state control means is a game history initialization capable of initializing the game history information when it is determined that the game state initialization process is performed by the game state initialization processing means. You may make it control to a possible state.
In this case, the game history information is initialized together with the game history initialization process in the initial setting state without separately performing the game history initialization process for initializing data for controlling the game and the game history information. Initialization can be performed.

  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) 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 between an interrupt mode that generates an external interrupt according to the number of times) and a timer mode (an interrupt mode that generates an internal interrupt according to the number of clock inputs of the CPU 41a).

  In the present embodiment, among the interrupts 1 to 4, interrupt 2 is set to the counter mode, interrupt 3 is set to the timer mode, and interrupts 1 and 4 are unused. The trigger terminal CLK / TRG is connected to the above-described power failure detection circuit 48, and the CPU 41a generates an interrupt 2 in response to the input of the voltage drop signal output from the power failure detection circuit 48, and the power failure described later. Execute interrupt processing. Further, the CPU 41a generates an interrupt 3 every time the number of clock inputs reaches a certain number, that is, every certain time interval (about 0.56 ms in this embodiment), and performs a timer interruption process (main) described later. Execute. 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 (not shown) for performing this refresh operation. The refresh register 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, and the value is updated every execution time of one instruction. .

  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 later. The CPU 41a also has a function of updating a numerical value of a specific register by the above-described timer interrupt process (main), and acquiring the updated numerical value as a random number (hereinafter, this function is referred to as a software random number function).

  The 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.

  On the effect control board 90, electrical components such as a liquid crystal display 51 (see FIG. 1) disposed on the front door of the slot machine 1, an effect LED 52, speakers 53 and 54, a reel LED 55, a selection switch 56, a decision switch 57, and the like. Are connected, and these electric components are driven based on control by a sub-control unit 91 (described later) mounted on the effect control board 90.

  Similar to the main control unit 41, the effect control board 90 includes a microcomputer having a CPU 91a, ROM 91b, RAM 91c, and I / O port 91d. The effect control board 90 includes a sub control unit 91 for effect control and an effect control board 90. A liquid crystal driving circuit 92 that controls the driving of the connected liquid crystal display 51, a lamp driving circuit 93 that controls the driving of the effect LED 52 and the reel LED 55, an audio output circuit 94 that controls audio output from the speakers 53 and 54, and a power source A reset circuit 95 that gives a reset signal to the CPU 91a when it is turned on or when an initialization command from the CPU 91a is not inputted, a clock device 96 that outputs time information including date information and time information, and other circuits are mounted. The CPU 91a receives a command transmitted from the game control board 40 and produces an effect. Performs various controls Utame, directly or indirectly controls each unit of the onboard control circuit performance control board 90.

  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 the command transmission lines. An interrupt is generated based on the input to acquire a command from the main control unit 41 and execute a command reception interrupt process to be stored in the buffer. The CPU 91a executes a timer interrupt process (sub) to be described later by generating an interrupt every time the number of clock inputs reaches a certain number, that is, every certain interval. Also, when an unused interrupt occurs in the CPU 91a, an unused interrupt process for immediately returning to the original process is executed.

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

  The sub-control unit 91 is 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.

  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.

  Further, when confirming the set value, the set value switch 37 is turned on when the bet number can be set (including a state where a medal can be inserted) during the BET process described later. The set value is displayed on the display 24, and the mode shifts to a set value confirmation mode in which the set value set at that time can be confirmed. Then, when the setting key switch 37 is turned off, the state shifts to a state in which the game can proceed.

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

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

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

  Even when the set bet number is not the bet number according to the gaming state, or when the set value used for the internal lottery is not an appropriate value, it is determined that the RAM is abnormal and the RAM abnormal error code is set and the RAM is set. The game is controlled to an abnormal error state and the progress of the game is disabled. As described above, 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, there are a regular bonus and a normal gaming state as the gaming state. Among these, 1 is defined as the prescribed number of bets corresponding to the regular bonus, and the prescribed number of bets corresponding to the normal gaming state is 3 is defined. For this reason, when the gaming state is a regular bonus, the game can be started when the betting number is set to 1, and when the gaming state is the normal gaming state, the game is started when the betting number is set to 3. Can be started. In this embodiment, when a specified number of bets corresponding to the gaming state is set, all winning lines L1 to L5 are activated, and the specified number corresponding to the gaming state is If it is 1, all winning lines L1 to L5 are activated when 1 is set as the bet number, and if the specified number is 3 according to the gaming state, 3 is set as the bet number. All winning lines L1 to L5 are activated.

  In the slot machine 1 of this embodiment, when all the reels 2L, 2C, 2R are stopped, the activated pay line (in the present embodiment, all the pay lines are always enabled. The activated winning line is simply referred to as a winning line), and a winning combination is obtained when a combination of symbols called a combination is arranged on the winning line. The type of winning combination is determined according to the game state, but it can be roughly divided into a small role with payout of medals and a replay that can start the next game without the need to set the number of bets. There are a game combination and a special combination with a transition of the game state. Below, a small role and a re-playing role are collectively called a general role. In order for winning of each combination determined according to the gaming state to occur, it is necessary to win an internal lottery to be described later and set a winning flag of the combination in the RAM 41c.

  Of the winning flags for each of these combinations, the winning flag for the small role and the re-playing role is valid only in the game in which the flag is set, and is invalid in the next game. It is valid until the combination of combinations permitted by the flag is complete, and is invalid in a game having the combination of combinations permitted. In other words, once the winning flag for a special role is won, even if the combination of characters allowed by the flag cannot be aligned, the winning flag is not invalidated and carried over to the next game. It becomes.

  FIG. 4A shows the winning combination table. The winning combination table is stored in advance in the ROM 41b of the main control unit 41, and the combination numbers (1 to 14) assigned in the order in which the lottery is performed corresponding to combinations of combinations and combinations to be selected in the internal drawing. ) Is registered.

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

  In the slot machine 1 of the present embodiment, as shown in FIG. 4A, the combination of combinations and combinations of combinations that are subject to lottery differ depending on whether the gaming state is a normal gaming state or a regular bonus. . Furthermore, when the gaming state is the normal gaming state, it depends on whether any special role is being carried over (whether any special role has already been set in the winning flag of the special role). The combination of combinations and combinations that are subject to lottery are different. In this embodiment, a state number corresponding to the gaming state is assigned, and when performing an internal lottery, a state number corresponding to the current gaming state is set, and a role to be a lottery object is determined according to this state number. It becomes possible to specify. Specifically, when no special combination is carried over in the normal gaming state, “0” is set as the state number, and when any special combination is carried over in the normal gaming state, “1” is set as the state number, and “2” is set as the state number in the case of a regular bonus.

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

  Cherry is awarded when the “Cherry” symbol is derived on one of the winning lines for the left reel in any gaming state, and two medals are paid out in the normal gaming state. 15 medals are paid out. If the “Cherry” symbol stops at the upper or lower level of the left reel, the combination of cherries will be aligned on the two winning lines L2 and L4 or the winning lines L3 and L5. Since you won the cherry on the winning line, 4 medals will be paid out in the normal gaming state, but in the regular bonus, even if you win the cherry on the 2 winning lines, one game Since the upper limit of the number of medals to be paid out at 15 is set to 15, only 15 medals are paid out. One (1) is awarded when the combination of “Blue 7-Red 7-Watermelon” is aligned on any of the winning lines in any gaming state, and one medal is paid out in the normal gaming state. In the regular bonus, 15 medals are paid out. One (2) is awarded when the combination of “Red 7-Blue 7-Watermelon” is aligned on any of the winning lines in any gaming state, and one medal is paid out in the normal gaming state. In the regular bonus, 15 medals are paid out. A bell is awarded when a combination of “Bell-Bell-Bell” is placed on any of the winning lines in any gaming state, and in the normal gaming state, 8 medals are paid out. 15 medals are paid out.

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

  The regular bonus is awarded when a combination of “red 7-red 7-BAR” is arranged on any of the winning lines in the normal gaming state. When the regular bonus is won, the gaming state shifts from 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.

  The big bonus is awarded when a combination of “red 7-red 7-red 7” or a combination of “blue 7-blue 7-blue 7” is arranged on any of the winning lines in the normal gaming state. When the big bonus is won, the gaming state shifts to the big bonus. When transitioning to the big bonus, the transition to the regular bonus is performed at the same time as the transition to the big bonus, and when the regular bonus ends, if the big bonus has not ended, the transition is made to the regular bonus again and repeated until the big bonus ends Controlled by regular bonus. That is, during the big bonus, the regular bonus is always controlled. The big bonus ends when the total number of medals paid out to the player in the big bonus reaches 466. At this time, the regular bonus is ended regardless of whether the regular bonus end condition is satisfied. While the gaming state is the big bonus, the big bonus medium flag is set in the RAM 41c.

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

  Hereinafter, the internal lottery of the present embodiment will be described. In the internal lottery, it is determined whether or not the above winning combination is permitted before the display results of all the reels 2L, 2C, and 2R are derived and displayed (actually, when the start switch 7 is detected). To do. In the internal lottery, first, as will be described later, a random number for internal lottery (an integer from 0 to 16383) is acquired. And, for each combination of combinations and combinations determined according to the gaming state, according to the obtained random number for internal lottery and the number of judgment values of each combination of combinations and combinations determined according to the gaming state and setting value Done. In this embodiment, based on the number of judgment values for each combination and combination of combinations, a range of determination values for each of the general combination and special combination, and a range of determination values for the combination of general combination and special combination is won. And the winning in the internal lottery is not exclusive, and a general combination and a special combination may be won simultaneously in one game.

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

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

  When the gaming state is the normal gaming state and any special combination is carried over, that is, when the status number is set to “1”, the winning combination table is referred to and the combination numbers 10 to 10 are referred to. 14 roles and combinations of roles, that is, replay [role number 10], cherry [role number 11], 1 sheet (1) [role number 12], 1 sheet (2) [role number 13], bell [role number 14 ] Are sequentially read out as a target combination of the internal lottery.

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

  In the internal lottery, the number of judgment values determined for the combination or combination of roles that is the subject of the internal lottery is sequentially added to the random number for internal lottery, and when the addition result overflows, It is judged that it was won.

  When a winning combination of any combination or combination of roles is determined, a special combination storing work and a general combination storing work assigned to the RAM 41c with a winning flag corresponding to the combination of winning combination or combination determined to be winning Set to. Specifically, when any of the roles (special roles) of the role numbers 1 to 3 is elected, the winning flag of the special role indicating that the special role is won is set in the special role storing work, and the general role is stored. Clear the winning flag set for the workpiece. In addition, when any of the role numbers 4 to 9 (special role + general role) is won, a special role winning flag indicating that the special role is won is set in the special role storing work, A winning combination flag indicating that the general combination is won is set in the general combination storing work. If any of the combination numbers 10 to 14 (general combination) is won, a general combination winning flag indicating that the general combination is won is set in the general combination storing work. If no winning combination is selected, only the general winning combination work is cleared.

  The number of determination values of each combination and combination of combinations is read according to the storage address of the number of determination values registered in the role-specific table stored in advance in the ROM 41b of the main control unit 41.

  FIG. 4B is a diagram illustrating an example of the role-specific table. 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 is registered in correspondence with the above-described state number that can specify the gaming state. This is because even if the combination is the same combination or combination, the winning probabilities may differ depending on the gaming state. The number of determination values 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”).

  In the role-specific table, as shown in FIG. 4B, a big bonus (1), a big bonus (2), a regular bonus, a big bonus (1) + cherry, a big bonus (2) + cherry, a big bonus ( 1) +1 (1), Big Bonus (2) +1 (1), Big Bonus (1) +1 (2), Big Bonus (2) +1 (2), Replay, Cherry, 1 (1) One (2), the storage address of the number of determination values of the bell is registered.

  Big Bonus (1), Big Bonus (2), Regular Bonus, Big Bonus (1) + Cherry, Big Bonus (2) + Cherry, Big Bonus (1) +1 (1), Big Bonus (2) +1 ( 1), Big Bonus (1) + 1 (2), Big Bonus (2) + 1 (2) are the roles that are subject to internal lottery when no special roles are carried over in the normal gaming state The storage address of the number of determination values corresponding to the state number 0 is registered. For the big bonus (1), the big bonus (2), and the regular bonus, the common flag is 0, and the storage address of the number of determination values is individually registered according to the set value. Big Bonus (1) + Cherry, Big Bonus (2) + Cherry, Big Bonus (1) +1 (1), Big Bonus (2) +1 (1), Big Bonus (1) +1 (2), Big For bonus (2) +1 (2), the common flag is 1, and the storage address of the common number of determination values is registered regardless of the set value.

  Replay is a combination that is subject to internal lottery regardless of whether or not a special combination is carried over in the normal gaming state, and a storage address for the number of determination values corresponding to state numbers 0 and 1 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, 1 (1), 2 (2) are the roles that are subject to internal lottery in any gaming state, the storage address of the number of determination values corresponding to state numbers 0 and 1, state number 2 And the storage address of the number of determination values corresponding to each are 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.

  The bell is a role that is subject to internal lottery in any gaming state, and has a storage address for the number of determination values corresponding to state numbers 0 and 1 and a storage address for the number of determination values corresponding to state number 2. Each is registered. The common flag for this combination is 0, and the storage address for the number of determination values is individually registered according to 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 cherry, which is a small role, 1 (1), 1 (2), and a bell, are the targets for paying out medals when winning a prize. These small roles can be awarded in any gaming state, but when the state number is 2, that is, when the gaming state is a regular bonus, when the state number is 0, that is, the gaming state More medals are paid out than when in the normal gaming state. In addition, when “cherry” stops at the upper or lower stage of the left reel, the combination of cherries is aligned on the two pay lines as described above, so the total number of payouts is paid out. It will be. In this embodiment, since the number of cherries paid out is 2 in the normal gaming state, 4 medals are paid out. In the regular bonus, the number of cherries paid out is 15, but the total number exceeds the upper limit of 15, so in this case, 15 medals are paid out.

  The big bonus (1), the big bonus (2), and the regular bonus winning are accompanied by a transition of the gaming state, and are not eligible for paying out medals. The replay does not involve the payout of medals, but it is substantially the same as the payout of 3 medals since it is not necessary to insert medals for setting the bet amount in the next game (always the normal game state).

  FIG. 5 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, when the address ADD is a game state of state number 0, that is, in a state where no special combination is carried over in the normal game state, the target combination of the internal lottery is the big bonus (1) and the set value is 1. This is an address to be referred to. At this time, 15 which is a value stored here is acquired as the number of determination values. Addresses ADD + 2, ADD + 4, ADD + 6, ADD + 8, and ADD + 10 are addresses that are referred to when the target role of the internal lottery is the big bonus (1) and the set value is 2 to 6 in the gaming state of state number 0. . Addresses ADD + 12, ADD + 14, ADD + 16, ADD + 18, ADD + 20, and ADD + 22 are addresses that are referred to when the internal lottery target role is the big bonus (2) and the set value is 1 to 6 in the game state of state number 0. It is. Addresses ADD + 24, ADD + 26, ADD + 28, ADD + 30, ADD + 32, and ADD + 34 are addresses that are referred to when the target character of the internal lottery is a regular bonus and the set value is 1 to 6, respectively, in the gaming state of state number 0.

  Regarding the big bonus (1) and big bonus (2) in the gaming state of state number 0, that is, in the state where no special combination is carried over in the normal gaming state, the number of judgment values is individually stored according to the set value. In addition, since different numbers of determination values are stored, the winning probabilities of these combinations and combinations of combinations differ depending on the set values.

  On the other hand, for the regular bonus in the game state of state number 0, that is, in the state where no special combination is carried over in the normal game state, the number of determination values is individually stored according to the set value. Since the number of determination values is stored, the regular bonus winning probability is the same for any set value.

  In addition, the address ADD + 36 is set to the set value when the internal lottery target role is big bonus (1) + cherry in the game state of state number 0, that is, in the state where no special role is carried over in the normal game state. Regardless of the address to be referred to, the address ADD + 38 is the big bonus (2) + in the game state of the state number 0, that is, in the normal game state where no special combination is carried over. This address is referred to regardless of the set value when it is a cherry, and the address ADD + 40 is an object of the internal lottery in the game state of the state number 0, that is, in the state where no special role is carried over in the normal game state This address is referenced regardless of the setting value when the winning combination is a big bonus (1) + 1 (1) The address ADD + 42 is a set value when the internal lottery target role is a big bonus (2) +1 piece (1) in the game state of state number 0, that is, in a state where no special combination is carried over in the normal game state Regardless of the address that is referenced, the address ADD + 44 is a big bonus (1) in the game state of state number 0, that is, in the normal game state where no special combination is carried over. +1 (2) is an address that is referred to regardless of the set value, and the address ADD + 46 is an internal number in the game state where the special number is not carried over in the state number 0, that is, the normal game state. This address is referred to regardless of the set value when the target combination of the lottery is big bonus (2) +1 (2).

  The address ADD + 48 is an address that is referred to regardless of the set value when the state number is 0 and the state number is 1, that is, in the normal gaming state, the target combination of the internal lottery is replay.

  The address ADD + 50 is an address that is referred to regardless of the set value when the state number is 0 and the state number is 1, that is, in the normal gaming state, when the subject combination of the internal lottery is cherry. The address ADD + 52 is an address that is referred to regardless of the set value when the state number is 2, that is, in the regular bonus, when the target part of the internal lottery is cherry.

  The address ADD + 54 is an address that is referred to regardless of the set value when the state number is 0 and the state number is 1, that is, in the normal gaming state, when the number of the internal lottery target is one (1). The address ADD + 56 is an address that is referred to regardless of the set value when the state number is 2, that is, in the regular bonus, when the number of the internal lottery target is one (1).

  The address ADD + 58 is an address that is referred to regardless of the set value when the state number is 0 and the state number is 1, that is, in the normal gaming state, when the number of the internal lottery target is one (2). The address ADD + 60 is an address that is referred to regardless of the set value when the state number is 2, that is, in the regular bonus, when the number of the internal lottery target is one (2).

  Addresses ADD + 62, ADD + 64, ADD + 66, ADD + 68, ADD + 70, and ADD + 72 are in the game state of state number 0 and state number 1, that is, in the normal game state, and the target role of the internal lottery is Bell and the set value is 1-6 This address is referred to by Addresses ADD + 74, ADD + 76, ADD + 78, ADD + 80, ADD + 82, and ADD + 84 are addresses that are referenced when the target number of the internal lottery is the bell and the set value is 1 to 6 in the game state of state number 2, that is, the regular bonus. It is. Regarding the bell in the gaming state of the gaming state 2, the number of determination values is individually stored according to the set value, but the number of determination values of the setting values 1 and 2, the number of determination values of 3 and 4, 5 and 6 Since the common determination value number is stored in each of the determination value numbers, the winning probabilities of the setting values 1 and 2 are the same, the winning probabilities of the 3 and 4 are common.

  FIGS. 6A to 6C are diagrams illustrating an example of a relationship between a value of a random number for internal lottery, the number of determination values of each combination and combination of combinations, and winning. FIG. 6 (a) shows a case where no special combination is carried over in the normal gaming state, and FIG. 6 (b) shows a case where any special combination is carried over in the normal gaming state. Here are examples of regular bonuses. 6A to 6C show an example in which the set value is 6.

  For example, as shown in FIG. 6A, when no special combination is carried over in the normal gaming state, the big bonus (1), the big bonus (2), the regular bonus, the big bonus (1) + Cherry, Big Bonus (2) + Cherry, Big Bonus (1) +1 (1), Big Bonus (2) +1 (1), Big Bonus (1) +1 (2), Big Bonus (2) +1 (2), Replay, Cherry, 1 (1), 1 (2), and Bell are subject to internal lottery, and in the set value 6, the number of determination values for each combination is 20, 20, 31, 10 10, 5, 5, 5, 5, 2245, 96, 163, 163, 2082. The big bonus (1), which is the target of the internal lottery, is the result of adding the judgment value number of 20 and the result of addition overflows when 16364 to 16383 are acquired as random numbers for the internal lottery. Become.

  Next, the big bonus (2) that is the subject of the internal lottery is obtained by adding 40, which is the sum of the judgment value number 20 of the big bonus (1) and the judgment value number 20 of the big bonus (2). The winning combination is obtained when 16344 to 16363, which will overflow, are obtained as random numbers for internal lottery. Similarly, the regular bonus is a big bonus when 16313-16343 is acquired as a random number for internal lottery, and the big bonus (1) + cherry is a big bonus when 16303 to 1631 is acquired as a random number for internal lottery. (2) + Cherry is obtained when 16293-16302 is obtained as a random number for internal lottery, Big Bonus (1) +1 (1) is obtained when 16288-16292 is obtained as a random number for internal lottery , Big Bonus (2) + 1 (1), 16283-16287 are acquired as random numbers for internal lottery, Big Bonus (1) + 1 (2), random numbers for internal lottery are 16278-16282 As a big bonus (2) + 1 (2), 16273-16277 are random numbers for internal lottery The replay is obtained when 14028-16272 is obtained as a random number for internal lottery, and the cherry is obtained when 13932-14027 is obtained as a random number for internal lottery (1 ) When 13769-13931 is acquired as a random number for internal lottery, 1 (2), when 13606-13768 is acquired as a random number for internal lottery, When it is acquired as a random number for lottery, it is determined that each is a win. When 0 to 11523 are acquired as random numbers for internal lottery, all combinations are lost.

  The approximate winning probability of each combination and combination of combinations calculated based on the number of judgment values is the big bonus (1), big bonus (2), regular bonus, big bonus (1) + cherry, big bonus ( 2) + Cherry, Big Bonus (1) +1 (1), Big Bonus (2) +1 (1), Big Bonus (1) +1 (2), Big Bonus (2) +1 (2), Replay , Cherry, 1 (1), 1 (2), bell, 1 / 819.2, 1 / 819.2, 1 / 528.5, 1/1638, 1/1638, 1/3277, 1/3277, 1/3277, 1/3277, 1 / 7.3, 1 / 170.7, 1 / 100.5, 1 / 100.5, and 1 / 7.87.

  In addition, as shown in FIG. 6B, when any special combination is carried over in the normal gaming state, only replay, cherry, 1 (1), 1 (2), and bell are inside. Since the number of determination values for each combination is 2245, 96, 163, 163, 2082 at the set value 6, it is 14139-16383, 14043-14138, 13880-14042, 13717-13789, 11635. When ˜13716 are acquired as random numbers for internal lottery, each is determined to be a winner. In addition, the approximate winning probabilities of the respective combinations are 1 / 7.3, 1 / 170.7, 1 / 100.5, 1 / 100.5, and 1 / 7.87. When 0-11634 is acquired as a random number for internal lottery, all combinations are lost.

  In addition, as shown in FIG. 6C, in the regular bonus, only the cherry, 1 (1), 1 (2), and bell are subject to the internal lottery. Since the number of determination values is 96, 163, 163, and 15919, when 16288 to 16383, 16125 to 16287, 15962 to 16124, and 43 to 15961 are acquired as random numbers for internal lottery, they are determined to be winning. In addition, the approximate winning probabilities for each combination are 1 / 7.1 and 1/128. When 0 to 55823 are acquired as random numbers for internal lottery, all the combinations are lost.

  Next, stop control of the reels 2L, 2C, 2R will be described.

  The CPU 41a refers to the table index and table creation data stored in the ROM 41b when the reel starts rotating and when the reel stops and the reel that is still rotating still remains. Create a stop control table for each reel. When one of the stop switches 8L, 8C, and 8R corresponding to the rotating reel is effectively detected, the stop control table of the corresponding reel is referred to and the referred stop control table is drawn. Based on the number of frames, control is performed to stop the rotation of the reels 2L, 2C, 2R corresponding to the operated stop switches 8L, 8C, 8R.

  As shown in FIG. 7, the table index contains table creation data from the reference address (table_index) when referring to the table index, according to the setting state of the winning flag by internal lottery (hereinafter referred to as the internal winning state). The difference up to the address where the index data indicating the head address of the stored area is stored is registered. As a result, a difference corresponding to the internal winning state is acquired, and the corresponding index data can be acquired by adding the difference to the reference address (table_index).

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

  The table creation data is composed of drawn-in frame number data indicating the number of drawn-in frames corresponding to the stop operation position, and an address of drawn-in frame number data to be referred to in accordance with the reel stop status.

  The number-of-drawing frame data referenced according to the reel stop status is whether all reels are rotating, only the left reel is stopped, only the middle reel is stopped, only the right reel is stopped, or left Depending on whether the middle reel is stopped, the left and right reels are stopped, the middle and right reels are stopped, and in the situation where any one of the reels is stopped, Since it may vary depending on the stop position of the stopped reel, the address of the number of frames to be drawn to be referred to is registered for each rotating reel for each situation, and based on the top address of the table creation data , It is possible to specify the address of the number of frame data to be referred to according to each situation, and it is necessary according to each situation from this identified address. It has to be able to identify the lead-frame number data. Even if the reel stop status and the stop position of the stopped reel are different, the same address is registered as the address for the number of drawn frames when the same number of drawn frames is applied. In such a case, the same data for the number of drawn frames is referred to.

  The drawn frame number data is data that can specify the number of drawn frames for each timing at which the stop operation is performed. In this embodiment, stepping motors that make one turn at a cycle of 168 steps (0 to 167) are used for the reel motors 32L, 32C, and 32R. That is, when the reel motors 32L, 32C, and 32R are driven for 168 steps, the reels 2L, 2C, and 2R make one round. Although not particularly shown, 21 areas (frames) divided every 8 steps (the number of steps in which one symbol moves) are defined with respect to one reel, and these areas include the reel reference position. 1 to 21 are assigned. On the other hand, the number of symbols arranged on one reel is 21, and symbol numbers 1 to 21 from the reel reference position are assigned to symbols on each reel, so symbols 1 to 21 are assigned to each reel. , Area numbers 1 to 21 are assigned in order. The number of drawn frames by area number is compressed and stored according to a predetermined rule in the number of drawn frames data so that the number of drawn frames by area number can be acquired by expanding the number of drawn frames data. It has become.

  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, and as shown in FIG. 8, addresses of 7E00 (H) to 7FFF (H) are assigned to each byte, as well as important work. , General work, special work, set value work, unsaved work, unused area, stack area.

  The important work is a 40-byte area from 7E00 (H) to 7E27 (H). Various bonuses such as various display devices, 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). This work stores data that can be initialized at the end of the big bonus, such as the total number of payouts.

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

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

  The non-saved 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. 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 46-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 this embodiment, as shown in FIG. 9A, the CPU 41a of the main control unit 41 does not destroy the data in the RAM 41c before starting the setting (before shifting to the setting change mode), at the end of the big bonus, or at the time of activation. At the time, when four initialization conditions at the end of one game are satisfied, four types of initializations with different areas initialized according to each initialization condition are performed.

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

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

  FIG. 9B shows an initialization table. In the initialization table, the start address and the initialization size are registered corresponding to the initializations 1 to 4 as described above.

  In initialization 1, 7E00 (H) is registered as the start address, and 1D3 (H) + M (size of unused stack area: (stack pointer−7FD2)) bytes are registered as the initialization size. 7E00 (H) to 1D3 (H) + M bytes are initialized. Then, as shown in FIG. 8, important work, general work, special work, set value work, unsaved work, general work, unused area, and unused stack area are allocated to address areas that continue from 7E00 (H). The sum of the sizes of these areas is 1D3 (H) + M bytes. Therefore, in initialization 1, 7D00 (H) is initialized to 1D3 (H) + M bytes, so that These areas are initialized in the order of general work, special work, set value work, non-saved work, general work, unused area, and unused stack area.

  In initialization 2, two start addresses and initialization sizes for each address are registered. This is because the general work initialized in the initialization 2 is allocated to two separate address areas. In initialization 2, 7E28 (H) is registered as the start address of the area to be initialized first, 67 (H) bytes are registered as the initialization size, and 7EB7 (H) is set as the start address of the area to be initialized next. Since 119 (H) + M bytes are registered as the conversion sizes, in initialization 2, an area for 7E28 (H) to 67 (H) bytes and an area for 7EB7 (H) to 119 (H) + M bytes Is initialized. The size of the general workpieces 7E28 (H) to 7E8E (H) is 67 (H) bytes. As shown in FIG. 8, 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 119 (H) + M bytes. Therefore, in initialization 2, 7E28 (H) to 67 (H) bytes are initialized, By initializing 7EB7 (H) to 119 (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 CE (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 CE (H) + M bytes Is initialized. As shown in FIG. 8, the unsaved work is an area of 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 sum of the sizes of these areas is CE (H) + M bytes, in initialization 3, 7EB7 (H) to 3 (H) bytes are initialized, and 7F05 (H) to CE (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 CE (H) + M bytes are registered as the initialization size. Therefore, in initialization 4, an area from 7F05 (H) to CE (H) + M bytes is registered. Is initialized. As shown in FIG. 8, the unused area and the unused stack area are allocated to address areas that are continuous from 7F05 (H), and the total size of these areas is CE (H) + M bytes. Therefore, in initialization 4, the CE (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, commands that the CPU 41a of the main control unit 41 transmits to the effect control board 90 will be described.

  In the present embodiment, the CPU 41a of the main control unit 41 makes a BET command, an internal winning command, a reel rotation start command, a reel stop command, a winning determination command, a payout start command, a payout end command, a gaming state to the effect control board 90. A plurality of types of commands including a command, a standby command, an abort command, an error command, a setting start command, a setting end command, a setting confirmation start command, a setting confirmation end command, and an initialization command are transmitted.

  The BET command is a command that can specify the number of medals inserted, that is, the number of medals used to set the bet number. Sent when

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

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

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

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

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

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

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

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

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

  The setting start command is a command indicating the start of the setting change mode, and is transmitted when the setting is started, that is, when the mode is changed to the setting change mode. The setting end command is a command that indicates the end of the setting change mode, the set setting value, and the like, and is transmitted when the setting ends, that is, when the setting change mode ends.

  The setting confirmation start command is a command indicating the start of the setting value confirmation mode, and the setting key switch 37 in a state where a bet amount can be set in a BET process (including a state where a medal can be inserted) which will be described later. Is transmitted when the mode shifts to the set value confirmation mode based on the fact that is set to ON. The setting confirmation end command is a command indicating the end of the setting value confirmation mode, and is transmitted when the setting key switch 37 is turned off in the setting value confirmation mode and the setting value confirmation mode ends.

  The initialization command is a command indicating that the gaming state has been initialized, and is transmitted at the end of initialization 1 described above.

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

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

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

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

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

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

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

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

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

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

  When a standby command is received, a standby pattern for executing a standby effect is referred to as a control pattern.

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

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

  When the setting start command is received, a setting notification pattern for notifying that the setting is being changed is referred to.

  When a setting confirmation start command or an initialization command is received, an initialization pattern described later is referred to as a control pattern. That is, when the setting confirmation start command or the initialization command is received, the game store setting mode is entered in which the game history data can be initialized.

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

  Then, the CPU 91a calculates the RAM parity based on the data stored in all the areas of the RAM 91c at the time of activation, and is based on the data stored in the RAM 91c on the condition that the RAM parity is 0. It is designed to return to the production state before the interruption. Specifically, the control pattern executed last is referred to and control based on the control pattern is executed. As a result, an effect based on the control pattern executed before power interruption is executed from the beginning.

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

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

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

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

  Next, access to the RAM 41c is permitted (Sa5), and it is determined whether or not the setting key switch 37 is in an ON state (Sa6). If the setting key switch 37 is not in the ON state in step Sa6, the RAM parity of all storage areas (including the unused area and the unused stack area) of the RAM 41c is calculated (Sa7). Is determined (Sa8). If the power interruption interrupt processing is normally performed, the RAM parity should be 0. If the RAM parity is not 0 in the step of Sa8, the data stored in the RAM 41c is not normal. An error code indicating abnormality is set in the register (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. In the case other than 5A (H), the data in the RAM 41c is not normal, so an error code indicating a RAM abnormality is set in the register (Sa10), and the process proceeds to the error processing shown in FIG.

  In the error processing, as shown in FIG. 11, the current display state of the game auxiliary display 12 is saved in the stack (Sb1), and the error code stored in the register is displayed on the game auxiliary display 12 (Sb2). .

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

  If it is determined in step Sb3 that the error code is not an error other than a RAM abnormality, it is determined whether an operation of the reset / setting switch 38 is detected (Sb5), and the reset / setting switch 38 is detected. If the operation of the reset switch 23 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 Sb5 or when the operation of the reset switch 23 is detected in the step Sb6, the error code stored in the register is cleared (Sb7 ), The display state of the game auxiliary display 12 is returned to the display state saved in the stack in the step Sb1 (Sb8), and the process returns to the original process.

  As described above, in the error processing, if the error processing is other than the RAM 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. 10, if it is determined in step Sa9 that the destructive diagnosis data is normal, the data in the RAM 41c is normal, and therefore the unstored 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 step Sa6, the process shifts to the setting change mode, and initialization 1 is performed to initialize all storage areas in the RAM 41c except the used stack area. (Sa15), the value stored in the set value work (0 at this time) is corrected to 1 (Sa16). Next, an interrupt is permitted (Sa17), and the setting change process shown in FIG. 12, that is, the setting change mode is entered (Sa18). After the setting change process is completed, the process proceeds to the game process.

  In the setting change process, as shown in FIG. 12, the setting value stored in the setting value work of the RAM 41c (the value of the setting value work is corrected to 1 before shifting to the setting changing process. Is read out (Sc1).

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

  When the operation of the start switch 7 is detected in the step of Sc3, the changed set value selected at that time is stored in the set value work of the RAM 41c and the set value is confirmed (Sc7). Wait until the setting key switch 37 is turned off (Sc8). If it is determined in step Sc8 that the setting key switch 37 is OFF, the flow returns to the flowchart of FIG. 10 and the game process is started.

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

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

  FIG. 13 is a flowchart showing the control contents of the game process executed by the CPU 41a.

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

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

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

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

  In the winning determination process in the step Sd4, when it is determined in the step Sd3 that the rotation of all the reels 2L, 2C, and 2R is stopped, the winning is determined according to the display result derived for each reel 2L, 2C, and 2R. A process of determining whether or not it has occurred is executed.

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

  In the game end process in the step of Sd6, a process of setting a gaming state in preparation for the next game is executed. In this game end process, initialization 4 for initializing the unused area and the unused stack area in the storage area of the RAM 41c is performed every game, and at the end of the big bonus, the storage area of the RAM 41c. Among these, initialization 2 is performed in which the general work, the unused area, and the unused stack area are initialized.

  FIG. 14 is a flowchart showing the control contents of the internal lottery process executed by the CPU 41a in step Sd2.

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

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

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

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

  In step Se5, random number acquisition processing is performed. In the random number acquisition process, interrupts are first prohibited. 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 a general-purpose register (not shown).

  Next, the lower byte value and upper byte value of the random number stored in the general-purpose register are exchanged with each other by using the register for circle calculation, and then the random-value value stored in the general-purpose register is ORed with 8080h. . 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 is acquired as a random number for internal lottery. Then, after permitting the prohibited interrupt, the random number acquisition process is terminated, and the process returns to the flowchart of FIG.

  Returning to FIG. 14, when the random number acquisition process is completed, the process proceeds to step Se <b> 6, the state number (any one of 0 to 2) is stored in the RAM 41 c according to the game state of the game, and the process proceeds to step Se <b> 7. In the step of Se7, in the gaming state indicated by the state number, the hand number to be drawn first is stored in the RAM 41c, and the process proceeds to the step of Se8. In the step of Se7, when the state number is 0, that is, when any special combination is not carried over in the normal gaming state, 1 (big bonus (1)) is set as the combination number to be drawn first. When the state number is 1, that is, when any special combination is carried over in the normal game state, 10 (replay) is first set as the combination number to be drawn, and the state number is 2. That is, in the case of a regular bonus, 11 (cherry) is first set as the winning number to be drawn.

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

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

  In the step of Se10, it is confirmed whether or not the common flag registered in the role-specific table of FIG. 4B is 1 in association with the role number to be processed. If not 1, the process proceeds to Step Se12.

  In the step of Se11, the address (see FIG. 5) of the storage area of the judgment value number of the ROM 41b registered in the role-specific table of FIG. 4B in association with the processing target role number is read. Then, the number of determination values stored at this address is acquired, and the process proceeds to Step Se13.

  In the step of Se12, first, the set value stored in the RAM 41c is read, and further, the ROM 41b registered in the role-specific table of FIG. 4B in association with the set role number to be processed and the read set value. Read the address of the storage area for the number of judgment values. Then, the number of determination values stored at this address is acquired, and the process proceeds to Step Se13.

  In the step of Se13, the number of determination values acquired in the step of Se11 or Se12 is added to the random number value for internal lottery, and the result of the addition is set as a new random number value. The process proceeds to the step of Se14, and the number of determination values is determined by internal lottery. It is determined whether an overflow has occurred when added to the random number value. The occurrence of an overflow indicates that the winning combination corresponding to the processing target winning number has been won. If an overflow occurs, the process proceeds to step Se16. If no overflow has occurred, the process proceeds to step Se15.

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

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

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

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

  FIG. 15 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 the initialization 1, first, the initialization table in the ROM 41b is referred to, and the start address and the initialization size registered corresponding to the initialization 1 are read (Sf1). A pointer is set to the read start address (7E00 (H)) (Sf2). Next, the size of the unused stack area (M = stack pointer−7FD2 (H)) is calculated (Sf3), and the number of bytes (1D3 (H) + M) of the area to be initialized is set (Sf4). Then, a RAM clear process for clearing data from the start address set in Sf2 over the number of bytes set in Sf4 is executed (Sf5). When the RAM clear process is completed, the initialization 1 is completed. Return to.

  FIG. 16 is a flowchart showing the control contents of the RAM clear process executed in step Sf5 of FIG.

  In the RAM clear process, the 1-byte data indicated by the address indicated by the pointer is cleared to 0 (Sf101), and the initialization byte number (the number of bytes set as the area to be initialized) is decremented by 1 (Sf102). 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 (Sf103). If the number of initialized bytes after subtraction is not 0, the pointer is advanced by 1 (Sf104), the process returns to Sf101, and the processes of Sf101 to S4 are repeated until the number of initialized bytes becomes 0. If the number of bytes to be initialized after subtraction is 0 in step Sf103, the initialization of all the specified number of bytes has been completed, so the RAM clear process is terminated and the process returns to the original process. .

  FIG. 17 is a flowchart showing the control contents of initialization 2 executed by the CPU 41a at the end of the big bonus in the Sd8 game end process.

  In the initialization 2, first, interrupts are prohibited (Sf11), and the start address and the initialization size registered corresponding to the initialization 2 are read with reference to the initialization table of the ROM 41b (Sf12). 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. (Sf13), the number of bytes (67 (H)) of the area to be initialized first is set (Sf14), and the data is cleared from the start address set in Sf13 over the number of bytes set in Sf14. (See FIG. 16) is executed (Sf15). 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 (Sf16), and the size of the unused stack area (M = stack pointer− 7FD2 (H)) is calculated (Sf17), and the number of bytes (119 (H) + M) of the second area to be initialized is set (Sf18). Then, a RAM clear process (see FIG. 16) for clearing data from the start address set in Sf16 to the number of bytes set in Sf18 is executed (Sf19), and when the RAM clear process is completed, it is prohibited in the step of Sf11. The interrupt that has been made is permitted (Sf20), and the process returns to the original process even after the initialization 2 is completed.

  FIG. 18 is a flowchart showing the control contents of initialization 3 executed when the data in the RAM 41c is normal in the startup process by the CPU 41a.

  In the initialization 3, first, the initialization table in the ROM 41b is referred to, and the start address and the initialization size registered corresponding to the initialization 3 are read (Sf21). 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. (Sf22), the number of bytes (3 (H)) of the area to be initialized first is set (Sf23), and the data is cleared from the start address set in Sf22 over the number of bytes set in Sf23. (See FIG. 16) is executed (Sf24). When the RAM clear process is completed, a pointer is set to the start address (7F05 (H)) of the second area to be initialized among the read start addresses (Sf25), and the size of the unused stack area (M = stack pointer− 7FD2 (H)) is calculated (Sf26), and the number of bytes (CE (H) + M) in the second area to be initialized is set (Sf27). Then, a RAM clear process (see FIG. 16) for clearing data from the start address set in Sf25 to the number of bytes set in Sf27 is executed (Sf28). When the RAM clear process is completed, initialization 3 is completed. Return to the original process.

  FIG. 19 is a flowchart showing the control contents of initialization 4 executed by the CPU 41a for each game in the game end process of Sd8.

  In the initialization 4, first, interrupts are prohibited (Sf31), and then 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 (Sf32). A pointer is set to the read start address (7F05 (H)) (Sf33). Next, the size of the unused stack area (M = stack pointer−7FD2 (H)) is calculated (Sf34), and the number of bytes (CE (H) + M) of the area to be initialized is set (Sf35). Then, a RAM clear process (see FIG. 16) for clearing data from the start address set in Sf33 to the number of bytes set in Sf5 is executed (Sf36), and when the RAM clear process is completed, it is prohibited in the step of Sf31. The interrupt that has been made is permitted (Sf37), and the process returns to the original process even after the initialization 4 is completed.

  FIG. 20 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 (Sg1). 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 (Sg2). 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 (Sg3). At this time, if the voltage drop signal is not input, the register saved in the stack area in Sg2 is restored (Sg4), the interrupt prohibited in the step of Sg1 is permitted (Sg5), and the process before the interrupt is performed. Return.

  If a voltage drop signal is input in step Sg3, destruction diagnosis data (5A (H) in this embodiment) is set (Sg6), and all output ports are initialized (Sg7). . 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 (Sg8), and access to the RAM 41c is performed. Prohibited (Sg9).

  Then, except for the determination of whether or not the voltage drop signal is input (Sg10, where Sg10 is the same process as Sg3), the process enters a loop process in which no process is performed. That is, when the voltage decreases as it is, the operation is stopped internally. Therefore, the CPU 41a reliably stops operation when the power is interrupted. Further, in this loop processing, when the voltage recovers and the voltage drop signal is not input, the above-described startup processing is executed, and if the RAM parity is 0 and the destructive diagnosis data is normal, the original processing is performed. It will return to.

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

  Next, game history data storage and browsing processing by the sub-control unit 91 will be described.

  In the present embodiment, the RAM 91c of the sub-control unit 91 mounted on the effect control board 90 is provided with a game history data storage area capable of storing game history data relating to already played games, and these game histories. The data is sequentially updated to the latest data based on the command transmitted from the main control unit 41. On the other hand, in the ROM 91 b of the sub-control unit 91, effect introduction data that introduces effects performed in the slot machine 1 is stored.

  Then, the player operates the selection switch 56 and the determination switch 57 except during the game (the period from the start of the game to the end of the game), whereby the game history data storage area of the RAM 91c is stored. It is possible to browse game history information based on game history data (excluding setting change history described later) stored in, and effect introduction data stored in the ROM 91b.

  The game history data storage area includes a bonus game number counter, a bonus game number table, a total game number counter, an RB counter, a BB (1) counter, a BB (2) counter, an insertion number counter, a payout number counter, and a time difference. It consists of a number table, a history table by date, and a setting value change table.

  The inter-bonus game number counter is a counter for counting the number of games from the end of the previous bonus (BB (1), BB (2), RB), and every time a game state command is received in a state other than the bonus state. It is incremented by 1 and cleared when a gaming state command indicating a transition from BB (1), BB (2) or RB to the normal gaming state is received.

  The inter-bonus game number table is a table that stores the number of inter-bonus games together with the type of bonus (BB (1), BB (2) or RB) for each bonus. BB (1), BB When the game state command indicating the transition to (2) or RB is received, the type of bonus is stored, and the value of the game number counter between bonuses is acquired and stored as the number of games between bonuses.

  The total game number counter is a counter that counts the total number of games of today, and is incremented by 1 every time a game state command is received in a state other than the bonus state.

  The RB counter is a counter that counts the number of RBs for today, and is incremented by 1 when a gaming state command indicating a transition from the normal gaming state to the RB is received.

  The BB (1) counter is a counter that counts the number of BB (1) s of today, and is incremented by 1 when a gaming state command indicating a transition from the normal gaming state to BB (1) is received. The BB (2) counter is a counter that counts the number of BB (2) times today, and is incremented by 1 when a gaming state command indicating a transition from the normal gaming state to BB (2) is received.

  The inserted number counter is a counter that counts the number of pachinko balls used in the game, that is, the number of balls taken in for use in setting the number of bets. When an internal winning command is received, A value (number of bets × 5) corresponding to the number of bets specified from the received BET command is added.

  The payout number counter is a counter that counts the number of pachinko balls that have been paid out as prize balls, and when receiving a prize determination command indicating a prize accompanying the prize balls, the number of prize balls specified by the command is determined. Is added.

  The hourly difference sheet table is a table that stores a difference sheet (a value of a payout sheet counter−a value of an input sheet counter) at a predetermined interval, and is based on time information acquired from the clock device 96 (for example, 5 Every minute), the payout number counter value and the input number counter value are acquired, and the difference number is calculated and stored.

  The history table by date includes the game number table between bonuses for the past three days, the total game number counter, the RB counter, the BB (1) counter, the BB (2) counter, the inserted number counter, the payout number counter, and the hourly difference number table. It is a table which stores each data. The sub-control unit 91 acquires date information from the timepiece device 96 when the activation process (sub) is performed, and stores the acquired date information in the date storage area of the RAM 91c. Then, it is determined whether or not the date information newly acquired in the activation process matches the date information stored in the date storage area of the RAM 91c, and when it is determined that they do not match, that is, the date has been updated, The data stored in the area two days ago is stored in the area three days ago, the data stored in the area one day ago is stored in the area two days ago, and the data stored in the area today is 1 The data stored in the area of the previous day and the data stored in the area where the data of today is stored are cleared (initialized). That is, the data of the bonus game number table, the total game number counter, the RB counter, the BB (1) counter, the BB (2) counter, the insertion number counter, the payout number counter, and the hourly difference number table are used as data one day ago. The storing process is performed.

  In addition, in the history table classified by date of the present embodiment, game history data for the past three days is stored, but data for the past three days or more may be stored.

  In addition, each date of the bonus game number table, total game number counter, RB counter, BB (1) counter, BB (2) counter, insertion number counter, payout number counter, and time difference number table is stored in the date-specific history table. As it is stored, the bonus game number table, total game number counter, RB counter, BB (1) counter, BB (2) counter, insertion number counter, payout number counter, and hourly difference number table are cleared. .

  The setting value change table is a table for storing the setting value change history for the past five times. When the setting end command is received, the setting end is associated with the time information (date and time) acquired from the clock device 96. Stores the setting value indicated by the command. At this time, the oldest change history is cleared.

  The setting of the time (date, time) of the clock device 96 mounted on the effect control board 90 is, for example, an effect control board 90 into which a wiring connector extending from the game control board 40 (effect relay board 80) is inserted. An external clock device (not shown) is connected to the upper connector, and the sub-control unit 91 monitors the acquisition of a time setting command indicating time information output from the external clock device, and the external clock device The time setting of the timepiece device 96 mounted on the effect control board 90 may be performed on the basis of the acquisition of the time setting command output from. In this way, for example, the operation control board 90 is provided with an operation switch for adjusting the time, and the time setting can be easily performed even if the operator does not set the time by operating the operation switch while looking at the external clock. Can be done.

  Here, the browsing situation of game history information and effect introduction data and the control situation of the sub-control unit 91 at that time will be described with reference to FIG.

  In the present embodiment, if any of the selection switch 56 and the decision switch 57 is detected in a period other than the game being executed, that is, a period from when the game state command is received to when the internal winning command is received, the liquid crystal is detected. The browsing menu screen shown in FIG. 21A is displayed on the display 51.

  The browsing menu screen has an explanation area for the currently selected menu, and a menu area consisting of “bonus information”, “introduction”, “bonus history”, “slump graph”, and “return”. In response to the detection of the switch 56, the selection frame of the menu area is moved, and the display content of the explanation area is also updated to the explanation of the currently selected menu area with this movement. Note that only the menu area corresponding to the setting state of the browsing effective flag set in the RAM 91c is displayed on the browsing menu screen, and “inter-bonus information” “direction introduction” “bonus history” “ In the “slump graph”, the menu area of the item for which the browsing valid flag is not set is not displayed. The browsing valid flag is set only for items that are set to enable browsing on the option screen described later, and for items that are not set to enable browsing on the option screen described later Cannot be browsed by the player's operation.

  When the determination switch 57 is detected in the state where the “inter-bonus information” menu area is selected on the browsing menu screen, the inter-bonus information screen shown in FIG. 21B is displayed. On the bonus information screen, a menu area consisting of “Today”, “1 day ago”, “2 days ago”, “3 days ago”, and “Return”, and a bonus information and the number of bonus games for each bonus are displayed. And an area. When displaying the bonus information screen from the browse menu screen, the type of bonus and the number of bonus games for the bonus in the bonus information display area based on the data registered in the bonus game number table for today. Is displayed for each bonus. Further, when the determination switch 57 is detected in a state where any one of “1 day ago”, “2 days ago”, and “3 days ago” is selected on the inter-bonus information screen, it is based on the data stored in the history data table by date. The type of bonus on the selected day and the number of bonus games are displayed in the bonus information display area for each bonus. Further, when the determination switch 57 is detected in a state where “return” is selected on the bonus information screen, the screen returns to the browsing menu screen.

  When the determination switch 57 is detected in a state where the menu area of “production introduction” is selected on the browsing menu screen, the production introduction screen shown in FIG. 21C is displayed. On the bonus information screen, a menu area corresponding to each effect and a menu area corresponding to “return” are provided. When the determination switch 57 is detected in a state where any of the menu areas corresponding to each effect is selected on the effect introduction screen, the corresponding data is extracted from the effect introduction data stored in the ROM 91b and displayed. . Further, when the determination switch 57 is detected in a state where “return” is selected on the effect introduction screen, the display returns to the browsing menu screen.

  When the determination switch 57 is detected in a state where the menu area of “bonus probability” is selected on the browsing menu screen, the bonus probability screen shown in FIG. 21D is displayed. The bonus probability screen is provided with a menu area consisting of “Today”, “1 day ago”, “2 days ago”, “3 days ago”, and “Return”, and a bonus probability display area in which the probability is displayed for each bonus type. . Then, when displaying the bonus probability screen from the browsing menu screen, today's BB probability and RB probability based on the values of the total game number counter, RB counter and BB (1) counter, and BB (2) counter of today. Is calculated and displayed in the bonus probability display area. Further, when the decision switch 57 is detected in a state where any one of “1 day ago”, “2 days ago”, and “3 days ago” is selected on the bonus probability screen, the selection is made based on the data stored in the history data table by date. The probability of BB (1), BB (2) and the probability of RB for the selected day are calculated and displayed in the bonus probability display area. Further, when the determination switch 57 is detected in a state where “return” is selected on the bonus probability screen, the screen returns to the browsing menu screen.

  When the determination switch 57 is detected in the state where the menu area of “slump graph” is selected on the browsing menu screen, the slump graph screen shown in FIG. The slump graph screen includes a menu area including “today”, “1 day ago”, “2 days ago”, “3 days ago”, and “return”, and a graph display area in which a slump graph indicating the status of the difference ball in time series is displayed. , Is provided. When displaying the slump graph screen from the browsing menu screen, today's slump graph is generated based on today's hourly difference number table and displayed in the graph display area. In addition, if any one of “1 day ago”, “2 days ago”, and “3 days ago” is selected on the slump graph screen and the determination switch 57 is detected, the selection is made based on the data stored in the history data table by date. A slump graph for the selected day is generated and displayed in the graph display area. Further, when the “return” is selected on the slump graph screen and the determination switch 57 is detected, the screen returns to the browsing menu screen.

  As described above, the player operates the selection switch 56 and the determination switch 57 except during the game (the period from the start of the game to the end of the game), so that the game history data in the RAM 91c is obtained. It is possible to view game history information based on game history data (excluding setting change history described later) stored in the storage area and effect introduction data stored in the ROM 91b.

  Further, in this embodiment, it is possible to clear the above-described game history data, set game history data that can be browsed by the player, and browse setting change history.

  Next, clearing of game history data, setting of game history data that can be browsed by the player, operation status when browsing the setting change history, and control status of the sub-control unit 91 at that time will be described with reference to FIG. To do.

  First, clearing of game history data, setting of game history data that can be viewed by the player, and viewing of setting change history are performed when the game state by the main control unit 41 is initialized, that is, when the setting key switch 37 is turned on. As described above, it can be executed in a game shop setting mode that is controlled when the power is turned on. In addition, since the initialization of the game state is based on the operation of a clerk at a game store, clearing the game history data, setting the game history data that can be viewed by the player, and viewing the setting change history are in principle It can only be done.

  Specifically, the sub-control unit 91 controls the game store setting mode when receiving an initialization command transmitted based on the fact that the main control unit 41 has performed the initialization 1 described above. Accordingly, the initialization menu screen shown in FIG. 22 is displayed on the liquid crystal display 51. In this initialization menu screen, the game history data can be cleared and the game history that can be viewed by the player. Data setting and setting change history can be viewed.

  Also, the game shop setting mode (display of the menu screen at initialization) is ended by operating the determination switch 57 in a state where a predetermined menu area displayed on the initialization menu screen is selected by the selection switch 56. When the setting end command is acquired from the main control unit 41 in a state where the game shop setting mode is being controlled (switching to the normal display screen) (while the menu screen is displayed during initialization), That is, when the game process is started, the game shop setting mode ends (switches to the normal display screen) without performing a predetermined end operation by the selection switch 56 or the setting switch 57.

  Further, the game shop setting mode (display of the menu screen at initialization) is performed without performing a predetermined end operation by the selection switch 56 or the setting switch 57 even when a BET command is acquired from the main control unit 41. The amusement shop setting mode ends (switches to the normal display screen). This is because the main control unit 41 can shift to the game process while the sub-control unit 91 is controlling the game store setting mode, so that the selection switch 56 and the setting switch 57 are detected and the setting end command is acquired. Is not recognized due to some trouble, it is conceivable that the game store setting mode will continue endlessly even though the player has performed a game progress operation.

  Therefore, when the BET command output from the main control unit 41 is acquired based on the effective detection of the operation related to the progress of the game (the medal insertion operation and the operation of the 1BET switch 5 and the MAXBET switch 6), If the setting mode (display of the menu screen at initialization) is terminated and the normal game screen is returned, the game store setting mode can be prevented from continuing indefinitely.

  In the present embodiment, the BET command output from the main control unit 41 based on the operation of the 1BET switch 5 and the MAXBET switch 6 which are examples of operations related to the progress of the game and the effective detection of the medal insertion is obtained. The game store setting mode is ended, for example, the internal winning command output from the main control unit 41 based on the valid detection of the start switch 7, or the valid of the stop switches 8L, 8C, 8R. The game shop setting mode may be terminated based on the acquisition of the reel stop command output from the main control unit 41 based on the detection.

  Also, in this embodiment, when the enter switch 57 is detected with the “return” menu area selected on the initialization menu screen, the setting end command is acquired, the BET command is acquired, and the amusement store When the setting mode is finished and the normal game screen is displayed, for example, when the selection / determination switch operation is not accepted for a predetermined time (for example, 30 seconds) while the menu screen is displayed during initialization. In addition, the game store setting mode may be automatically ended to return to the normal game screen.

  The initialization menu screen includes an explanation area for the currently selected menu and a menu area consisting of “history data clear”, “option”, “setting change history”, and “return”. In response to this detection, the selection frame of the menu area is moved, and the display content of the explanation area is also updated to the explanation of the currently selected menu area with this movement.

  As shown in FIG. 22A, when the determination switch 57 is detected in the state where the “history data clear” menu area is selected on the initialization menu screen, the history data clear screen shown in FIG. Display. The history data clear screen is provided with an explanation area for the currently selected menu and a menu area consisting of “Yes” and “No”. Then, when the determination switch 57 is detected in a state where “Yes” is selected on the history data clear screen, all the data except the setting change history among the game history data stored in the game history data storage area of the RAM 91c. Is cleared, a message indicating that the clearing of the history data has been completed is displayed as shown in FIG. 23B, and the screen returns to the initialization menu screen. If “NO” is selected on the history data clear screen and the determination switch 57 is detected, the game history data is not cleared and the screen returns to the initialization menu screen.

  As shown in FIG. 22B, when the history data determination switch 57 is detected in the state where the “option” menu area is selected on the initialization menu screen, the option screen shown in FIG. 24A is displayed. . The option screen is provided with a menu area including “information between bonuses”, “production introduction”, “bonus history”, “slump graph”, and “return”. Then, when the determination switch 57 is detected in a state where any one of “information between bonuses”, “introduction of presentation”, “bonus history”, and “slump graph” is selected on the option screen, the display of the corresponding viewable setting column is switched. Specifically, when “ON” indicating that browsing is enabled is displayed, it is switched to “OFF” indicating that browsing is not enabled, and “ON” is displayed when “OFF” is displayed. Switch to When the determination switch 57 is detected in a state where “return” is selected on the option screen, a browsing valid flag is set for an item for which “ON” is displayed in the browsing enable setting field, while “OFF” is displayed. After clearing the viewing valid flag of the item that has been set, it returns to the menu screen at initialization.

  As shown in FIG. 22C, when the determination switch 57 is detected in the state where the “setting change history” menu area is selected on the initialization menu screen, the setting change history screen shown in FIG. Display. The setting change history screen includes a setting change history display area for displaying the setting change history for the past five times, that is, a setting change history stored in the RAM 91c, and a menu area corresponding to “return”. Yes. When the determination switch 57 is detected while “return” is selected on the setting change history screen, the menu screen upon initialization is returned.

  As shown in FIG. 22D, when the determination switch 57 is detected in a state where the “return” menu area is selected on the initialization menu screen, the game store setting mode is terminated and the normal game screen is restored. .

  As described above, in the game store setting mode controlled when the game state by the main control unit 41 is initialized, that is, when the setting key switch 37 is turned on and the power is turned on, the initialization menu A screen is displayed. By operating the selection switch 56 and the decision switch 57 on the screen, it is possible to clear game history data, set game history data that can be viewed by the player, and view setting change history. Become.

  In this embodiment, even if the game history data is cleared, the setting change history data is not cleared. For example, even if the setting is changed illegally, the evidence is surely left. However, the setting change history data may be cleared together with the clearing of the game history data, or the game history data and the setting change history data may be cleared by separate operations. .

  Further, in this embodiment, a setting change history as an example of management information related to the management of the slot machine 1 is stored, and the setting change history can be confirmed in the game shop setting mode. Management information related to management is not limited to setting change history information. For example, the opening history of the front door of the slot machine 1, specifically, the opening time, the number of times of opening, etc. are stored based on the opening of the front door. The release history may be confirmed in the use mode.

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

  When the power is turned on and the CPU is reset, the CPU 91a performs a startup process (sub) shown in FIG.

  In the start-up process (sub), first, data check (parity check in this embodiment) of the RAM of the sub control unit 91 is performed (Sh1, Sh2). Specifically, the current parity is created, and it is determined whether or not the data being backed up is normal depending on whether or not it matches the parity stored before power interruption.

  If the check result is normal, the RAM diagnosis data created before the power interruption is confirmed (Sh3), and it is determined whether or not it is normal (Sh4). If the RAM diagnosis data is normal, all the registers are restored (Sh5), and then the interrupt prohibition is canceled (Sh6).

  If the result of the data check is not normal in the step of Sh2 or if the RAM diagnosis data is not normal in the step of Sh4, the effect state cannot be returned to the state at the time of power interruption, and is stored in the RAM 91c. After executing all initialization processing for initializing all data (Sh7), the prohibition of interrupt is canceled (Sh6).

  Then, after the prohibition of interruption is canceled in the step of Sh6, date information is acquired from the clock device 96 (Sh8), and the date specified from the acquired date information is stored in the date storage area of the RAM 91c. It is determined whether or not the date matches, that is, whether or not the date has been changed since the last activation processing was performed (Sh9), and is determined to match, that is, the date has not been changed. If so, the process proceeds to step Sh13.

  Further, if it is determined that the date does not match in the step of Sh9, that is, the date has been changed, the process proceeds to the step of Sh10, and the date stored in the date storage area of the RAM 91c is updated to the acquired date ( Sh10), data stored in the area two days ago in the date-specific history table is stored in the area three days ago, data stored in the area one day ago is stored in the area two days ago, and The stored data is stored in the area one day ago (Sh11). Then, after clearing (initializing) the area where today's data is stored (Sh12), the process proceeds to step Sh13.

  In this case, since the date change is from the previous day to today's day, the data stored in each area in the history table by date is stored in the previous day area, and the data in the current day is cleared. However, if the date change was from the previous day to today, for example, the data stored in each area in the date-specific history table is stored in the area two days ago, and the current day In addition, the history information for the number of days of change may be initialized, such as clearing the data of the area for two days on the previous day.

  In the step of Sh13, whether or not the initialization command transmitted from the main control unit 41 is buffered, that is, whether or not the initialization command is stored in the buffer of the RAM 91c in the command reception interrupt process described later. Monitoring is performed from the time when the prohibition of interruption is canceled in the step of Sh6 until a predetermined period elapses (Sh13, Sh14).

  Then, when the initialization command is acquired during the period from the time when the prohibition of interruption is canceled in the step of Sh6 until the predetermined period elapses, that is, initialization for initializing all data stored in the RAM 41c in the main control unit 41 When one process is executed (Sh13), data excluding data stored in the game history data storage area among data stored in the RAM 91c, that is, data related to effects of the sub-control unit 91 is initialized. The game initialization setting process is executed (Sh16), and the game history data is cleared, the game history data that can be browsed by the player is set, and the setting change history can be browsed. After executing the history data setting update process for the purpose (Sh17), it is normal in the timer interrupt process (sub) described later. Sets the normal processing flag for determining whether to perform physical (SH15), only the timer interrupt processing (sub) or command reception interrupt process will be described later, it moves to a loop process performed.

  Further, when the initialization command is not acquired during the period from the time when the prohibition of interrupt is canceled in the step of Sh6 until the predetermined period elapses, that is, all data stored in the RAM 41c is initialized in the main control unit 41. When the initialization 1 process is not executed, a normal process flag for determining whether or not to perform a normal process in a timer interrupt process (sub) described later is set (Sh15), and a timer interrupt described later is set. The process proceeds to loop processing in which only processing (sub) and command reception interrupt processing are performed.

  It should be noted that here, when the date change is made after the interrupt prohibition is canceled in the step of Sh6, the initialization command is used to transfer the data in the step of Sh11 and clear the data of the day in the step of Sh12. Regardless of whether or not the date is acquired, for example, when there is a change in date, for example, the data transfer in the step of Sh11 and the clearing of the data of the day in the step of Sh12 are performed, for example, It may be performed only when it is determined that the initialization command has not been issued after the attachment update, and when the history data is not initialized in the history data setting update process.

  In this embodiment, the CPU 41a of the main control unit 41 transmits an initialization command only when the initialization 1 process is performed when the power is turned on, and the initialization is performed when the power is turned on and the state returns to the state before the power interruption. The command is not transmitted, and the CPU 91a of the sub-control unit 91 monitors the initialization command for a predetermined period after canceling the prohibition of the interrupt, and receives the initialization command during this period to perform the main control. If the initialization of the control state of the unit 41 is determined and no initialization command is received during this time, it is determined that the control state of the main control unit 41 has returned to the state before the power interruption. For this reason, when the sub control unit 91 determines whether the control state of the main control unit 41 has been initialized or has returned, the main control unit 41 indicates that a plurality of types of commands, that is, the control state has been initialized. Since it is not necessary to transmit the command to indicate and the command to return to the state before power interruption, it is possible to reduce the control load on the main control unit 41 when the power is turned on.

  Further, in this embodiment, when the power is turned on, the power-on process in the CPU 91a of the sub-control unit 91 is completed for the CPU 41a of the main control unit 41, and a command from the main control unit 41 can be received. The reset signal is input for a period longer than the time required to achieve a proper state. Specifically, as shown in FIG. 28, after the reset signal to the CPU 91a is turned off and the timing when the CPU 91a starts (ta1) and after the CPU 91a starts, the interrupt prohibition is canceled and the command is received. At a timing (ta2) when a sufficient time (L1) has elapsed to enable the CPU 41a, the reset signal for the CPU 41a is turned off and the CPU 41a is started. Further, the time until the normal processing flag is set in the RAM 91c, that is, the timing of ending the monitoring of the initialization command is sufficient to execute the initialization 1 process and transmit the initialization command after the CPU 41a starts. It is designed to be the timing (ta3) when a long time (L2) has elapsed. Therefore, the CPU 91a can reliably receive the initialization command transmitted from the main control unit 41.

  Next, detailed control contents of the history data setting update process executed by the CPU 91a in the above-described step of Sh17 will be described based on the flowchart of FIG.

  In the history data setting update process, first, after switching to the game shop setting mode and displaying the initialization menu screen (see FIG. 22) on the display screen of the liquid crystal display 51 (Sh101), a setting end command or BET It is determined whether or not the command has been acquired, that is, whether or not the main control unit 41 has shifted to the game process (Sh102). If it is determined that the command has been acquired, the process proceeds to Sh125 and displayed on the display screen of the liquid crystal display 51. After finishing the initialization menu screen, the normal game screen is displayed (Sh128), the game shop setting mode is terminated, and the process returns to the step of Sh15.

  If it is determined in step S102 that neither the setting end command nor the BET command is acquired, the operation of the selection switch 56 and the determination switch 57 is monitored. That is, whether or not an operation for moving a selection frame for selecting a predetermined menu area from among “clear history data”, “option”, “setting change history screen”, and “return” in the menu screen at initialization is performed. It is confirmed whether or not an operation for determining the selected menu area has been performed (Sh103, Sh105).

  If the selection switch 56 is detected in step Sh103, the selection frame is moved to the next menu area (Sh104). If the selection frame is moved in the step of Sh104, or if neither of the selection switch 56 and the decision switch 57 is detected in the steps of Sh103 and 105, the process returns to Sh102, and the setting end command and BET command are acquired. The operation of the selection switch 56 and the determination switch 57 is monitored (Sh102 to Sh105).

  If the determination switch 57 is detected in the step of Sh105, in that state, which menu area is selected from the menu areas of “history data clear”, “option”, and “setting change history screen”. Confirm (Sh106, Sh115, Sh124), and if no menu area of “history data clear” “option” “setting change history screen” is selected, the “return” menu area is selected Therefore, after the initialization menu screen displayed on the display screen of the liquid crystal display 51 is terminated, the normal game screen is displayed (Sh128), the game shop setting mode is terminated, and the step of Sh15 is performed. Return.

  When the menu area of “history data clear” is selected with the determination switch 57 detected in the step of Sh105 (Sh106), after displaying the history data clear screen (see FIG. 23) (Sh107), It is determined whether or not a setting end command or a BET command has been acquired, that is, whether or not the main control unit 41 has shifted to game processing (Sh108). If it is determined that acquisition has been performed, the process proceeds to step Sh128. If it is determined that the setting is not acquired, the setting end command or BET command is acquired and the operation of the selection switch 56 and the determination switch 57 is monitored (Sh108, 109, 111). That is, it is confirmed whether or not an operation for moving the selection frame is performed in the “Yes” and “No” menu area on the history data clear screen, or whether or not an operation for determining the selected menu area is performed.

  When the selection switch 56 is detected in the monitoring state of Sh108, 109, and 111 (Sh109), the selection frame is moved to the next menu area (Sh110). Further, when the selection frame is moved in the monitoring state of Sh108, 109, 111 (Sh110), or when neither operation of the selection switch 56 and the determination switch 57 is detected in the steps of Sh109, 111, the process returns to Sh108. The acquisition of the setting end command or BET command and the operation of the selection switch 56 and the decision switch 57 are monitored again (Sh108, 109, 111).

  When the determination switch 57 is detected in the step of Sh111, in that state, it is confirmed which menu area is selected between “Yes” and “No” (Sh112), and the menu area of “Yes” is selected. In other words, when a clear operation is performed on the game history data clear screen, all data except for the setting change history is cleared from the game history data stored in the game history data storage area of the RAM 91c. Later (Sh113), a message indicating that the history data has been cleared is displayed (Sh114), and the process returns to the step of Sh101. That is, based on the determination switch 57 being detected in a state where the history data clear area is selected, all data except the setting change history is initialized among the game history data.

  When the setting end command or BET command is acquired in the monitoring state of Sh108, 109, 111, the normal game screen is displayed after the history data clear screen displayed on the display screen of the liquid crystal display 51 is ended. (Sh128), the game shop setting mode is terminated, and the process returns to the step of Sh15.

  In the state where the decision switch 57 is detected in the step of Sh105, when the “option” menu area is selected (Sh115), the option screen (see FIG. 24A) is displayed (Sh116), and the setting is made. The acquisition of the end command or BET command and the operation of the selection switch 56 and the decision switch 57 are monitored (Sh117, 118, 120). That is, among the “bonus information”, “introduction”, “bonus history”, and “slump graph” on the option screen, whether or not an operation for moving the selection frame has been performed or an operation for determining the selected menu area is performed. Check if it was done.

  When the selection switch 56 is detected in the monitoring state of Sh117, 118, 120 (Sh118), the next selection menu area is changed (Sh119). Further, when the selection menu area is changed or when neither the selection switch 56 nor the determination switch 57 is detected, the process returns to Sh117, and the acquisition of the setting end command or BET command and the selection switch 56, the determination switch 57 are again performed. Are monitored (Sh117, 118, 120). Further, when the setting end command or BET command is acquired in the monitoring state of Sh 117, 118, 120, the normal game screen is displayed after the option screen displayed on the display screen of the liquid crystal display 51 is ended ( Sh128), the game shop setting mode is terminated, and the process returns to the step of Sh15.

  When the decision switch 57 is detected in the monitoring state of Sh 117, 118, 120 (Sh 120), whether or not the “return” menu area is selected in that state is checked (Sh 121). When the menu area is selected, the browsing valid flag of the item for which “ON” is displayed in the browsing setting column is set, while the browsing valid flag for the item for which “OFF” is displayed is cleared. After (Sh122), the process returns to the step of Sh101.

  Further, when the “return” menu area is not selected in the step of Sh121, that is, when any other menu area is selected, the display of the corresponding viewable setting column is switched (Sh123). Specifically, when “ON” indicating that browsing is enabled is displayed, it is switched to “OFF” indicating that browsing is not enabled, and “ON” is displayed when “OFF” is displayed. And return to the step of Sh117.

  When the menu area of “setting change history” is selected with the determination switch 57 detected in the step of Sh105 (Sh124), after the setting change history screen (see FIG. 24C) is displayed ( Sh125), the operation of the decision switch 57 and the acquisition of the setting end command or BET command are monitored (Sh126, 127). That is, since only the “return” menu area can be selected in the setting change history screen, it is confirmed whether or not an operation for determining the menu area has been performed and the acquisition of the setting end command or the BET command is confirmed. When the determination switch 57 is detected, the process returns to the step of Sh101. Further, when the setting end command or BET command is acquired in the monitoring state of Sh126, 127, after the setting change history screen displayed on the display screen of the liquid crystal display 51 is ended, the normal game screen is displayed ( Sh128), the game shop setting mode is terminated, and the process returns to the step of Sh15.

  In this embodiment, the CPU 91a interrupts other processing as interrupt processing 1 based on detection of a strobe signal (interrupt signal) output when a command is transmitted from the main control unit 41, and performs command reception interrupt processing. In this command reception interrupt process, a command transmitted from the main control unit 41 is acquired and stored in a buffer provided in the RAM 91c.

  Further, the CPU 91a is configured to execute a timer interrupt process (sub) periodically (every 1.12 ms in this embodiment) as the above-described interrupt process 2 based on the output from the internal timer. In the interruption process, control for performing various effects is performed.

  FIG. 27 is a flowchart showing the control contents of the timer interrupt process (sub) by the CPU 91a.

  In the timer interrupt process (sub), first, the register is saved in the RAM (Si1), and after the timer interrupt process (sub) is completed, the process before the interrupt can be restored.

  Next, after executing switch detection processing for acquiring the detection status of various sensors, switches, and signals (Si2), it is determined whether or not the normal processing flag is set, that is, whether or not the initialization command monitoring period has ended. Confirm (Si3), and if the normal processing flag is set, it is confirmed that the command output from the main control unit 41 is buffered as having shifted to the game processing (Si4). If the normal processing flag is not set in the Si3 step, the process proceeds to the Si18 step.

  If the command is buffered in the step of Si4, it is confirmed whether the buffered command is any one of a gaming state command, an internal winning command, a standby command, and a setting end command (Si5, Si8 , Si10, Si14), if it is not any of these commands, the effect setting process for setting the control contents of the effect peripheral devices (liquid crystal display 51, lamp, LED, speaker) according to the contents of the buffered command (Si16), by performing an effect control process for controlling the peripheral device for effects according to the set control content (Si17), the effect state is controlled according to the command, and the process proceeds to step Si18.

  If the command buffered in the step of Si5 is a game state command, the game history data stored in the game history data storage area in the RAM 91c of the sub-control unit 91 is updated based on the received game state command. (Si6), the selection / determination switch valid flag indicating that the operation of the selection / determination switch (selection switch 56, decision switch 57) is valid is set (Si7), and the process proceeds to step Si18.

  If the command buffered in the Si8 step is an internal winning command, the selection / determination switch valid flag is cleared (Si9), and the process proceeds to the Si18 step.

  If the command received in the step of Si10 is a standby command, after setting the standby screen display flag (Si11), whether or not any game history data is displayed on the display screen of the liquid crystal display 51 at that time (Si12), if it is displayed, the process proceeds to Si18 as it is. If not displayed, a standby screen based on the standby command is displayed (Si13), and then the process proceeds to Si18.

  If the command received in step Si14 is a setting end command, the setting change history stored in the game history data storage area is updated (Si15), and then the process proceeds to step Si18.

  If no command is received in step Si4, it is confirmed whether the operation of the selection switch 56 and the determination switch 57 is valid based on the presence / absence of the selection / determination switch valid flag (Si21). If is valid, it is confirmed whether or not an operation of the selection / determination switch has been detected (Si22). If the operation of the selection / determination switch is not effective in the step of Si19 or if the selection / determination switch is not detected in the step of Si22, the process proceeds to the step of Si18 as it is.

  If the selection / determination switch is detected in the step of Si22, it is confirmed whether or not the operation is an operation for returning from the game history data screen to the normal game screen (Si23), and the normal game is played from the game history data screen. If it is not an operation for returning to the screen, it is determined that the operation is for browsing, and the display screen is updated according to the operation (Si24), and the process proceeds to step Si18. If the operation is to return from the game history data screen to the normal game screen in the step of Si23, it is confirmed whether or not the standby screen display flag is set (Si25). If the standby screen display flag is not set, The normal game screen is displayed (Si26), and the process proceeds to the Si18 step as it is. If the standby screen display flag is set, the standby screen is displayed (Si27), and the process proceeds to the Si18 step.

  In the step of Si18, counter update processing for updating various counters is performed. In the counter updating process, the insertion number counter and the payout number counter stored in the RAM 91c as game history data are also updated.

  Next, the content of the RAM of the sub-control unit 91, that is, the processing for normally performing the backup of the production state, more specifically, for confirming whether the data backed up in the above-described startup processing (sub) is normal or not. A backup process for creating and saving parity and RAM diagnostic data is performed (Si19). After the saved register in Si1 is restored (Si20), the process returns to the process before the interrupt.

  As described above, in the slot machine 1 of this embodiment, the history data setting update process for initializing the game history data stored in the RAM 91c is covered by the front door as described above when the power is turned on. A game shop setting mode that is controlled when the sub-control unit 91 determines that the initialization 1 process (Sa15), which is not executed unless the setting key switch 37 provided in the state is operated, is executed. This is performed when an initialization operation is performed by the operation of the selection / determination switch (selection switch 56, determination switch 57) in the initialization possible state), so that the player initializes the game history data without permission, It is possible to effectively prevent a problem that the player can only browse short-term game history data.

  The sub-control unit 91 acquires the date from the clock device 96 when the power is turned on, and stores the acquired date in the date storage area of the RAM 91c. When the date is acquired in the startup process, Determining whether the acquired date matches the date stored in the date storage area, and based on the determination result, the date is changed between the previous startup process and the startup process. It is determined whether or not there was. When the date is changed, an area in which the game history of today that needs to be initialized every day among the plurality of types of game history data stored in the RAM 91c is stored in the game store setting mode. It is initialized (cleared) without performing an initialization operation. In other words, today's game history data is initialized in accordance with the date change, thereby eliminating the work of game history data initialization work by game shop clerk and the like, thereby reducing the burden on the game hall.

  In the present embodiment, whether or not the date has been changed is determined by comparing the date stored at the time of the previous start processing with the date acquired at the time of the current start processing. The method for determining whether or not there is a date change is not limited to this, and is not necessarily limited to the method for determining based on the date as long as it can determine the date change. Time information is acquired from the device 96, and it is determined whether or not the acquired time is before a predetermined business start time (or after the end of business hours), and before the business start time (or after the end of the business hours) In some cases, today's game history data may be initialized.

  In the present embodiment, the date is acquired and stored when the startup process (sub) is executed, and whether the date has been changed between the previous startup process and the current startup process. The game history data of today is initialized based on the determination result, but the date is also stored when, for example, the slot machine is turned off (during end processing). Thus, it may be determined whether or not the date has been changed since the last time the slot machine was turned off, and the game history data of today may be initialized based on the determination result.

  Further, in this embodiment, it is determined whether or not the date has been changed based on the time information such as the time and date measured by the clock device 96 including a real time clock. For example, the counter mounted on the substrate 90 measures the time from when the last activation process is executed until the current activation process is executed, based on whether the measured time is 24 hours or more. It may be determined whether or not the date has been changed.

  Further, the initialization of the game history data can be performed together with the initialization 1 process executed by the main control unit 41 when the power is turned on, and a selection / determination switch used when browsing the game history data is used. Therefore, the initialization process can be reduced.

  In this embodiment, the sub-control unit 91 determines whether or not the main control unit 41 has executed initialization 1 when the power is turned on, and when it is determined that the initialization 1 has been executed, Although the game mode is controlled so that it can be initialized (display of the menu screen at initialization), for example, the main control unit 41 initializes 1 regardless of whether initialization 1 is executed or not. Is determined based on the acquisition of the setting start command, and when it is determined that the setting change mode has been entered, the game history data is initialized. It is also possible to control to a game store mode that can be made (display of a menu screen at initialization).

  Further, in the setting change mode, the main control unit 41 executes initialization 1 and determines whether or not the setting change processing has started, based on acquisition of a setting start command or the like, and initializes 1 and a new setting value. When it is determined that the setting process has been started, the game history data may be controlled to a game store mode (display of the initialization menu screen).

  Further, the RAM 91c in which the game history data is stored is provided on the effect control board 90 provided separately from the game control board 40, thereby effectively reducing the control load of the main control unit 41. The control board 90 is connected to the game control board 40 via the relay board 80 and is not directly connected to the game control board 40 on which the main control unit 41 for controlling the game is mounted. It can be prevented from being input to 41 and affecting the control of the game.

  Further, the sub-control unit 91 is in a state of waiting for reception of the initialization command from the main control unit 41 until a predetermined time elapses after the prohibition of interruption is canceled in the power-on processing, and the normal processing flag is set. Initialization indicating that the initialization 1 process was not performed when the RAM 41c initialization 1 process by the main control unit 41 was not performed when the power was turned on by waiting without setting. Even if the command or the like is not output to the sub-control unit 91, if the initialization command is not received during the predetermined period, the normal process flag is set and the normal process (timer interrupt process) is executed. Start control on. In this way, the sub-control unit 91 determines whether or not the initialization 1 process has been performed in the main control unit 41 without receiving an initialization command or the like indicating that the initialization 1 process has not been performed. Therefore, the types of commands output to the sub-control unit 91 can be reduced as much as possible, and the data storage area in the RAM 41c can be reduced.

  In addition, the sub-control unit 91 performs a setting change process when an operation for ending the initialization menu screen is performed in a state where the game shop setting mode is being controlled (when the initialization menu screen is being displayed). When a setting end command transmitted based on the completion is acquired, the game store setting mode is ended, and the game progresses in the state where the game store setting mode is controlled. Even when a BET command transmitted based on a betting number setting operation (one-BET switch 5, MAXBET switch 6, or medal insertion operation), which is a related operation, is acquired, the game store setting mode is ended. Therefore, even if the setting end command cannot be detected due to some trouble in the amusement shop setting mode, the BET command can be obtained. Since the gaming facility setting mode ends with the progress operation of the player, it is prevented that the game arcade setting mode would endlessly followed.

  In addition, even if the sub-control unit 91 receives a standby command while the game history data is displayed, the sub-control unit 91 does not switch to the standby screen until the end condition of the screen being displayed is satisfied, so the standby control is inadvertently performed. It is possible to prevent the player from feeling uncomfortable by switching to the screen display. In addition, when a standby command is received during display, the main control unit 41 does not transmit the standby command again after the display of the game history data by displaying the standby screen when the display of the game history data ends. Therefore, the control load on the main control unit 41 can be reduced.

  In addition, an operation of a setting key switch 37 (a switch provided in the housing and in a state where it cannot be operated unless the locking device is unlocked and the front door is opened) that can be operated only by a game shop clerk, etc. The option screen displayed on the display screen of the liquid crystal display 51 only when the power is turned on in the detected state is an example of management information necessary for the game store to manage the slot machine 1. Since the setting value change history and the like can be browsed, the store clerk at the amusement hall can easily confirm whether or not the setting (setting value) at the permissible stage has been illegally changed.

  In addition, in the option screen displayed on the display screen of the liquid crystal display 51 only when the power is turned on while the operation of the setting key switch 37 that can be operated only by a store clerk or the like is detected. Of the plurality of game history data stored in the RAM 91c of the sub-control unit 91, for example, predetermined game history data to be kept secret from the player is set by a game shop clerk and viewed from the player Not only can it be disabled, but the setting of game history data that allows display by the operation of the selection / decision switch is effective only when it is controlled in the game store setting mode, so it is hidden from the player It is possible to effectively prevent the game history data desired to be set from being viewed by a player or the like.

  Next, a modified example of the initialization of the RAM 41c will be described.

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

  In this case, each time 1 byte is cleared, it is determined whether the address indicated by the pointer is the end address. If the address is the end address, the initialization may be terminated. The initialization byte number from the start address to the common end address is calculated and set, and every time 1 byte is cleared from the start address, the initialization byte number is decremented by 1 and the pointer is advanced by 1. It is preferable that the process is executed until the number reaches 0, and it is determined that the area of the end address has been cleared when the number of initialization bytes reaches 0, and the initialization ends. 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. 29A is a diagram illustrating a modification of the storage area of the RAM 41c, FIG. 29B is a diagram illustrating a modification of the initialization table, and FIG. 30 is a modification of initialization 1. It is a flowchart to show.

  As shown in FIG. 29 (a), in this modification, the storage area of the RAM 41c is 7E00 (H), the set value work, special work, important work, non-saved work, general work, unused area, unused The stack area is allocated in the order of the stack area in use. For this reason, even if any of initialization 1, 2, and 4 is performed, the area | region initialized is a continuous address area | region. Specifically, the areas initialized in the initialization 1 are all areas except the in-use stack area, that is, set value work, special work, important work, unsaved work, general work, unused area, unused stack. These areas are continuous address areas from 7E00 (H) to the stack pointer. The areas initialized in the initialization 2 are general work, unused area, and unused stack area, and these areas are continuous address areas from 7E53 (H) to the stack pointer. The areas initialized in the initialization 4 are an unused area and an unused stack area. These areas are continuous address areas from 7F05 (H) to the stack pointer. In initialization 2, general work, unused area, and unused stack area are initialized. In initialization 3, non-saved work, unused area, and unused stack area are initialized. The unused area and the unused stack area that are initialized in the initialization 3 are continuous address areas, but the non-saved work is a non-continuous address area.

  As shown in FIG. 29 (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 stored in the ROM 41b is referred to, and the start address registered corresponding to the initialization 1 is read (Sf1001). Then, a pointer is set at the read start address (7E00 (H)) (Sf1002). Next, the initialization address common to the initializations 1 to 4 is read by referring to the initialization table of the ROM 41b (Sf1003). Then, the number of bytes from the start address (7E00 (H)) read in Sf1001 to the end address (stack pointer) read in Sf1003 is calculated (Sf1004), and the number of bytes in the area for initializing the calculated number of bytes is set. (Sf1005). Then, a RAM clear process for clearing data from the start address set in Sf1002 over the number of bytes set in Sf1005 is executed (Sf1006), and when the RAM clear process is completed, the initialization 1 is completed. Return to.

  In addition, the modification example of initializations 2 and 4 is almost the same processing as the modification example of initialization 1 shown in FIG. 30, 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.

  Next, a modified example such as an abnormality determination of data stored in the RAM 41c will be described.

  In the above-described 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. It is determined whether or not the data 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 whether or not the RAM parity of the RAM 41c is 1 at the time of restoration. By determining whether or not the data in the RAM 41c is normal, it 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. If the result is 00H, it is determined that the data in the RAM 41c is normal, and if it is not 00H, the data in the RAM 41c is abnormal. You may make it determine with it.

  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 This is because the result of calculating the checksum of all the areas including the specific area where the checksum of the RAM 41c is stored is 00H, so that the data of the RAM 41c can be determined to be normal.

  Even in this case, in the power interruption interrupt processing, before the checksum is calculated, the destructive diagnosis data (for example, 5AH) in which any bit is 1 is stored in a predetermined address, and at the time of recovery, In addition to determining whether or not the checksum is 00H, it is determined whether or not the data for destructive diagnosis is stored normally. The condition is that the checksum is 00H and the data for destructive diagnosis is also normal. In addition, it is preferable to determine that the data in the RAM 41c is normal. Even if the data in the RAM 41c is not normal, if 00H is stored in all areas, it is determined to be normal by the checksum determination at the time of startup, but any bit is set to 1 at the time of power failure. After destructive diagnostic data is stored, the checksum is calculated and stored in a specific area. In addition to checking the checksum at startup, the destructive diagnostic data is also checked. Even when all the areas are cleared to 0 and the checksum is 00H and is determined to be normal, the destruction diagnosis data does not match the value stored at the time of the power failure and is determined to be abnormal. It is possible to improve the accuracy of determining the abnormality of the data stored in.

  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 00H. In the interruption interrupt processing, the RAM parity of the RAM 41c is determined. Alternatively, a checksum is calculated and stored in a specific area, and at the time of recovery, a RAM parity or checksum excluding the specific area of the RAM 41c is calculated and compared with the RAM parity or checksum stored in the specific area. Data in RAM 41c is normal depending on whether the results match Whether may be determined. In this case as well, as described above, before the RAM parity or checksum is calculated, the destructive diagnosis data in which any bit is 1 is stored at a predetermined address. In addition to determining whether or not the sums match, it is determined whether or not the data for destructive diagnosis is stored normally, the RAM parity and checksum match, and the destructive diagnostic data is also normal. It is preferable to determine that the data in the RAM 41c is normal under the above conditions.

  In the above embodiment, 5AH is stored in the RAM 41c as failure diagnosis data in the power interruption processing. However, any data other than 0 can be stored and can be confirmed at startup. Even in the configuration, when all areas are cleared to 0 at startup, the data for destruction diagnosis 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. The accuracy of data abnormality determination can be increased.

  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. That is, the notification means controlled by the main control unit 41 notifies the sub-control unit 91 of a command indicating an error state in addition to the notification means controlled by the main control unit 41, and The notification unit controlled by the control unit 91 may notify the error, or the notification unit controlled by the main control unit 41 does not perform the notification, but the notification unit controlled by the sub control unit 91 does not perform the notification. An error notification may be performed.

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

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

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

  In this embodiment, when it is determined that the winning prize is determined in the internal lottery process and it is determined that the value is not an appropriate setting value, the RAM 41c is controlled to be in a RAM abnormal error state. When the set value stored in the set value work is not an appropriate value (a value in the range of 1 to 6), the winning of the winning is determined with a probability based on the initial value of the set value (for example, the set value 1). You may do it.

  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. Therefore, even if an illegal 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 the 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, but the unused area and / or the unused stack area of the RAM 41c is initialized. The timing for performing the conversion may be any timing during one game. For example, the unused area and / or the unused stack area of the RAM 41c may be initialized at the start of the game or when a process that is always executed for each game is executed. It may be one that performs the conversion.

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

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

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

  In the present embodiment, as described above, after being controlled to an error state due to a RAM abnormality error and the progress of the game being disabled, a setting value is newly selected and set based on a setting change operation in the setting change mode. Otherwise, the state in which the progress of the game is disabled is not canceled, but the disablement of the progress of the game may be canceled on the condition that the mode is changed to the setting change mode.

  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 interruption interrupt process, destruction diagnosis data (5AH in this embodiment) in which any bit is 1, that is, specific data other than 0 is stored in a predetermined address of the RAM 41c. After that, adjustment data for which the RAM parity is 0 based on all the data in the RAM 41c including the destructive diagnosis data is stored, and in addition to the determination of whether the RAM parity is 0 at the start-up, the destructive diagnosis data Is determined to be normal, and the RAM 41c is determined to be normal on the condition that the RAM parity is 0 and the destructive diagnosis data is also normally stored. The control state is restored based on the data stored in. As a result, when 00H 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, it is normal by the determination of the RAM parity at startup. If the data in the RAM 41c is 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. Therefore, it is possible to further improve the accuracy of determining whether or not the data in the RAM 41c has the correct contents at the time of activation.

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

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

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

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

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

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

  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 addition, other interrupts are prohibited during the execution of the power interruption interrupt process and the timer interrupt process (main). For example, the voltage drops during the execution of the timer interrupt process (main). Even when a signal is input, double interruptions do not occur, and it is possible to prevent the processing load on 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 the command, the interruption does not occur and the transmission of the command is not hindered, and the transmission can be completed normally before the CPU 41a stops driving. .

  If the interrupt timing of the power interruption interrupt processing and the interrupt timing of the timer interrupt processing (main) are simultaneous, that is, if interrupt 2 and interrupt 3 occur simultaneously, interrupt 2 Priority is given to the power interruption interrupt process, and if interrupt 2 occurs during the execution of the timer interrupt process (main), the power interruption occurs after the timer interrupt process (main) ends. Since interrupt processing is performed and power interruption interrupt processing is performed at the earliest possible stage while preventing multiple interrupts, it is ensured that power interruption interrupt processing is performed before the CPU 41a stops driving. It can be carried out.

  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.

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

  For example, in the above-described embodiment, the sub-control unit 91 controls the game shop setting mode when the initialization command output from the main control unit 41 is acquired, that is, the initialization 1 is performed in the main control unit 1. The game history data can be initialized by controlling to the game store setting mode only when the game is set, but the game store setting mode may be controlled except when the initialization command is acquired. Good.

  Specifically, the main control unit 41 is set when the setting key switch 37 is turned on in a state in which the bet number can be set (including a state in which medals can be inserted) during the BET process described above. It is possible to control to a set value confirmation mode in which the set value can be confirmed, a setting confirmation start command is transmitted to the sub-control unit 91 at the start of the set value confirmation mode, and at the end of the set value confirmation mode A setting confirmation end command is transmitted to the sub-control unit 91.

  The sub-control unit 91 controls the game shop setting mode when the setting confirmation start command is acquired, and detects the predetermined end operation described above or when the setting confirmation end command is acquired. The control of the game store setting mode may be terminated.

  In this way, the sub-control unit 91 can control the game shop setting mode even when the initialization command is not acquired. In such a case, the sub-control unit 91 is particularly in a position where it cannot be operated by the player. It is preferable to control the game shop setting mode based on the operation of the arranged switch (here, the setting key switch 37).

  In the above-described embodiment, the initialization 1 is performed on condition that the setting key switch 37 for shifting to the setting change mode is turned on when the power is turned on. In this case, the initialization 1 is not necessarily performed based on the detection of the operation switch that triggers the transition to the setting change mode. For example, when the power is turned on, the setting key switch 37 is The state shifts to a state where initialization 1 can be performed (for example, initialization mode) on condition that a separately provided RAM clear switch (not shown) or the like is operated, and initialization 1 can be performed. You may do it. That is, the setting change process and initialization 1 may be performed separately.

  In the above embodiment, the initialization 1 is performed when the setting key switch 37 is turned ON when the power is turned on and the mode is changed to the setting change mode. The initialization 1 may be performed based on the operation of a predetermined RAM clear switch (not shown) or the like.

  In the above embodiment, the sub-control unit 91 shifts to the game shop setting mode based on the acquisition of the initialization command from the main control unit 41. You may make it transfer to the game shop setting mode based on acquisition of the setting start (end) command transmitted based on the start (end) of the setting change process performed later. That is, the initialization command of the present invention may also be used as a setting start command.

  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.

  Further, in the above-described embodiment, the number of determination values referred to according to the gaming state (state number) for the same combination or combination of combinations at the same set value is different for each gaming state (state number). Was stored. That is, the same combination or combination of combinations with the same set value is stored separately even if the number of determination values referred to according to the gaming state (state number) is the same, but the gaming state (state number) Regardless of the combination of combinations or combinations of combinations that have the same winning probability regardless, the storage address of the judgment value number is shared, or the winning probability is the same regardless of the setting value and gaming state (state number) For the combination or combination of combinations, the storage address of the determination value number may be made common, and by storing the determination value number in common in this way, the storage capacity required for this is reduced. It will be enough.

  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, it can be determined whether or not an overflow has occurred in the subtraction result (here, the subtraction result becomes negative).

  Further, in the above embodiment, in the internal lottery, the number of determination values of each combination or combination of combinations corresponding to the gaming state is sequentially added to the acquired random number for internal lottery, and the addition result overflows The combination or combination of combinations was determined to be winning. On the other hand, a winning determination table that defines a range of determination values for determining each combination or combination as winning according to the number of determination values for each combination or combination according to the gaming state is determined for each game. The internal lottery may be performed by comparing the created and acquired random number value for internal lottery with the range of determination values of each combination or combination of combinations. In addition, a winning determination table in which a range of determination values for determining each combination or combination of combinations as winning is stored in the ROM 41b in advance, and the acquired random value for internal lottery is used as a range of determination values for each combination. It is good also as what performs an internal lottery by comparing with.

  In the above embodiment, the game can be started only by setting 3 as the number of bets in the normal gaming state. On the other hand, even in the normal gaming state, the game can be started by setting 1 as the bet number, and further, the game can be started by setting 2 as the bet number. Also good. As a result, when 1 or 2 is set as the bet number in the normal gaming state, the winning probability of the small role in the internal lottery is lowered as compared with the case where 3 is set as the bet number, and the small role is won The number of paid out medals can be increased. For example, when 3 is set as the bet number in the normal gaming state, the winning probability of Bell is 1 / 4.82 and the payout number is 7, but when 1 or 2 is set as the bet number, The winning probability may be lower than 1 / 4.82 and the payout number may be more than seven. 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 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.

  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 areas including the specific area where the checksum of the RAM 41c is stored is 00 (H), it is determined that the data in 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.

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

  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, 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.
