Description

  The present invention relates to a gaming machine capable of performing a predetermined game, and more particularly to a gaming machine that performs lottery in relation to a game such as a ball game machine or a slot machine.

  In this type of gaming machine, it is common to perform various lotteries in relation to the game. For example, in a ball game machine, when a game ball launched into a game area wins a start winning opening, a lottery is performed to determine whether or not to control a big hit state advantageous to the player, and this lottery is won. By doing so, it is common to control to the big hit state. In addition, in the slot machine, a lottery is performed to determine whether or not it is allowed to arrange winning combinations (combinations of winning symbols) on variable display devices such as reels at the timing when the game start operation is performed. In general, it is possible to align the winning winning combination in the variable display device on the condition that the winning is won.

  Such lottery in gaming machines is often performed by using a random number value that is latched at a timing when a lottery condition is satisfied and a random number value that is periodically updated within a certain range is used. Since it is counted up periodically, if a count-up cycle or a cycle in which the counter count value makes one round is detected by some means, a random value that matches the judgment value that is a big hit or the winning judgment value is generated When these random numbers are identified, the game is targeted at the timing at which random numbers that match the jackpot determination value or winning determination value are generated. It becomes possible to generate.

  For this reason, even after the power supply is stopped, the counter value is retained, and after the power is turned on next time, the random number value is restarted from the counter value retained before the power interruption. A game machine has been proposed in which it becomes difficult to specify the timing for generating a random value that matches the determination value that is a big hit or the winning determination value. Patent Document 1).

A random number circuit 42 for generating a signal, a pulse oscillator 43 for supplying a clock signal of a constant frequency to the random number circuit 42, and a detection signal input from a switch connected directly to the game control board 40 or via the power supply board 101. Switch detection circuit 44, motor drive circuit 45 that controls the drive of the reel motors 32L, 32C, and 32R, solenoid drive circuit 46 that controls the drive of the flow path switching solenoid 30, various displays and LEDs connected to the game control board 40 LED drive circuit 47 for controlling the driving of the power supply power supplied to the slot machine 1 When a voltage drop is detected, a power interruption detection circuit 48 that outputs a voltage drop signal indicating that to the main control unit 41, when the power is turned on or when an initialization command is not input from the main CPU 41a In addition, a reset circuit 49 for supplying a reset signal to the main CPU 41a and other various devices and circuits are mounted.

  The main CPU 41a has an interrupt function (including an interrupt prohibition function) such as a timekeeping function and a timer interrupt, executes a program (described later) stored in the ROM 41b, and performs processing related to the progress of the game. Each part of the control circuit mounted on the game control board 40 is controlled directly or indirectly. The ROM 41b stores fixed data such as programs executed by the main CPU 41a and various tables. The RAM 41c is used as a work area when the main 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, and detection states of various switches connected to the game control board 40 are input to the input port via these signal input terminals. The input state of these signal input terminals is monitored by the main CPU 41a, and the main CPU 41a executes basic processing that shifts in stages according to the input state of the signal input terminals, that is, the detection states of various switches.

  Further, the main 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, the counter mode (externally depending on the signal input from the trigger terminal provided separately from the signal input terminal) An interrupt mode for generating an interrupt) and a timer mode (an interrupt mode for generating an internal interrupt according to the number of clock inputs of the main CPU 41a) can be selected and set.

  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 is connected to the power interruption detection circuit 48 described above, and the main CPU 41a generates an interrupt 2 in response to the input of the voltage drop signal output from the power interruption detection circuit 48, and the power interruption interruption described later. Execute the process (main). Further, the main 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 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 the interrupts 1 and 4 occur, the main CPU 41a executes an unused interrupt process that immediately returns to the original process.

  The main 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 are generated simultaneously. In this case, interrupts that are 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 main 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 the interrupt process based on the occurrence of any of the interrupts 1 to 4. And the data saved in the stack area at the end of the interrupt process is returned to the register.

  Further, the main control unit 41 is supplied with backup power even during a power failure, and the data stored in the RAM 41c is held while the backup power is being supplied.

  The main CPU 41a repeatedly loops the process according to the control state until the detection state of the various switches connected to the game control board 40 is changed as a basic process, and step by step according to the change of the detection state of the various switches. Execute the process to move to. Further, the main CPU 41a has an interrupt function as described above, and can interrupt the basic process by the occurrence of the interrupt and execute the interrupt process. The voltage output from the power interruption detection circuit 48 The power interruption interrupt process (main) is executed in response to the input of the decrease signal, and the timer interrupt process (main) is executed at regular time intervals (about 0.56 ms in this embodiment). In addition, the execution interval of the timer interrupt process (main) is set to a time longer than the sum of the time required to complete the repeated process according to the control state in the basic process and the execution time of the timer interrupt process (main) Therefore, the process that is repeated according to the control state between the current and next timer interrupt processes (main) is completed at least once.

  The main 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.

  As shown in FIG. 5, the random number circuit 42 is mainly composed of a counter circuit 42a and a latch circuit 42b. The counter circuit 42a receives the clock signal output from the pulse oscillator 43, and increments the count value by 1 at the rising or falling edge of the clock signal. The counter circuit 42a is a 16-bit counter. Therefore, the output (that is, the count value) of the counter circuit 42a is output through 16 signal lines. The output of the counter circuit 42a is input to the latch circuit 42b. The count value of the counter circuit 42a is any one of 0 to 65535, and the value is incremented by 1. When the count value reaches 65535, it returns to 0.

  Although the oscillation frequency of the clock signal output from the pulse oscillator 43 is arbitrary, the count value of the counter circuit 42a is used by the main CPU 41a to generate a random number for internal lottery, so the oscillation frequency of the clock signal is The operating frequency of the main CPU 41a is different from that of the main CPU 41a, and the oscillation frequency of the clock signal is preferably not an integral multiple of the operating frequency of the main CPU 41a (for example, the operating frequency of the main CPU 41a is 15.872 MHz, Frequency 20 MHz). As will be described later, the main CPU 41a performs an operation on the count value of the software counter and the count value of the counter circuit 42a whose values are updated periodically (for example, approximately every 2.24 ms) to obtain a random number for internal lottery. This is because it is preferable to generate a random number that the update cycle of the count value of the software counter and the update cycle of the counter circuit 42a do not have an integer multiple relationship. Furthermore, it is more preferable that the oscillation frequency of the clock signal and the operating frequency of the main CPU 41a are frequencies that are not divisible by one.

  The detection signal of the start switch 7 is input to the latch circuit 42b as a latch signal, and the latch circuit 42b detects when the operation of the start switch 7 is detected, that is, when a game start operation is performed. By latching the count value of the counter circuit 42a in the buffer, the main CPU 41a can acquire the count value of the counter circuit 42a latched in the buffer in response to detection of the start switch 7.

  The random number circuit 42 is a circuit that generates a random number by hardware, and hereinafter, the random number generated by the random number circuit 42 is also referred to as a hard random number.

  In this embodiment, the output wiring (16 lines) of the counter circuit 42a is connected to the latch circuit 42b as it is, but the wiring may be shifted and connected. Note that “connect as it is” means that the wiring of the bit n (n: 0 to 15) of the counter circuit 42a is connected to the input of the bit n of the latch circuit 42b. That is, wiring is performed so that the same value as the count value output from the counter circuit 42a is latched by the latch circuit 42b. “Connected by shifting the wiring” means that the wiring of bit i (any one of i: 0 to 15) out of the 16 wirings from the counter circuit 42a is the bit j (j: 0 to 0) of the latch circuit 42b. 15) (i ≠ j). Note that two or more wirings that are connected in a shifted manner may be used. The output of the latch circuit 42b is input to the main CPU 41a via the input port in the main control unit 41. However, the wiring between the counter circuit 42a and the latch circuit 42b is not shifted, but the latch circuit 42b and the input port are not shifted. The wiring may be shifted and connected. In any case, the count value output from the counter circuit 42a is not the same as the value input to the main CPU 41a, and the value changes randomly instead of stepping one by one. It becomes more difficult to aim at the timing of a specific value from the outside.

  The effect control board 90 is connected to effect devices such as a liquid crystal display 51 (see FIG. 1), an effect LED 52, speakers 53 and 54, and the reel LED 55 described above, which are arranged on the front door 1b of the slot machine 1. These effect devices are driven based on control by a later-described sub-control unit 91 mounted on the effect control board 90.

  In this embodiment, the sub-control unit 91 mounted on the effect control board 90 controls the output of the effect devices such as the liquid crystal display 51, effect effect LED 52, speakers 53 and 54, and reel LED 55. However, in addition to the sub-control unit 91, an output control unit that directly controls the output of the effect device is mounted on the effect control board 90 or another board, and the sub-control unit 91 is based on a command from the main control unit 41. The output control unit may determine the output pattern of the effect device, and the output control unit may control the output of the effect device based on the output pattern determined by the sub control unit 91. In such a configuration, the sub control unit 91 and the output control may be performed. The output control of the rendering device is performed by both of the units.

  Further, in the present embodiment, the liquid crystal display 51, the effect effect LED 52, the speakers 53 and 54, and the reel LED 55 are exemplified as the effect device, but the effect device is not limited to these, for example, a mechanically driven display. A device or a mechanically driven item may be applied as the effect device.

  Similar to the main control unit 41, the effect control board 90 includes a sub CPU 91a, ROM 91b, RAM 91c, and a microcomputer provided with an I / O port 91d. The sub control unit 91 controls the effect, and the effect control board 90. A display control circuit 92 that performs display control of the liquid crystal display 51 connected to the LED, an LED driving circuit 93 that performs drive control 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, Supplied to a reset circuit 95 that gives a reset signal to the sub CPU 91a when the power is turned on or when an initialization command from the sub CPU 91a is not inputted for a certain period of time, a clock device 97 that outputs time information including date information and time information, and a slot machine 1 The power supply voltage is monitored, and when a voltage drop is detected, this is indicated The power interruption detection circuit 98 that outputs a pressure drop signal to the sub CPU 91a, other circuits, and the like are mounted. The sub CPU 91a receives a command transmitted from the game control board 40 and performs an effect. While performing various controls, each part of the control circuit mounted on the effect control board 90 is controlled directly or indirectly.

  Similar to the main CPU 41a, the sub CPU 91a has an interrupt function (including an interrupt prohibition function). One of the interrupt terminals 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, and the sub CPU 91a receives the strobe signal. 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. Further, the sub CPU 91a executes an 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. One of the interrupt terminals of the sub-control unit 91 is connected to the power interruption detection circuit 98, and the sub CPU 91a responds to the input of the voltage drop signal output from the power interruption detection circuit 98. Execute processing (sub). Further, when an unused interrupt occurs in the sub CPU 91a, an unused interrupt process for immediately returning to the original process is executed.

  Also, unlike the main CPU 41a, the sub CPU 91a interrupts the process even when the timer interrupt process (sub) is being executed when an interrupt is generated based on the input of the strobe signal (INT). The command reception interrupt process is executed at the same time, and the command reception interrupt process is executed with the highest priority even if interrupts that trigger the timer interrupt process (sub) occur at the same time. Note that command reception interrupt processing is also prohibited during the execution of power interruption interrupt processing (sub), but if an interrupt that triggers power interruption interrupt processing (sub) occurs at the same time, command reception Prioritize interrupt processing

  The sub-control unit 91 is also supplied with backup power at the time of a power failure, and the data stored in the RAM 91c is held while the backup power is supplied.

  In the slot machine 1 of the present embodiment, the medal payout rate changes according to the set value. Specifically, the medal payout rate is changed by using a winning probability corresponding to a set value in an internal lottery described later. The set value consists of 6 levels of 1 to 6, with 6 being the highest payout rate and the payout rate being lower as the value is decreased in the order of 243, 2 and 1. That is, when 6 is set as the set value, the advantage is highest for the player, and the advantage decreases step by step as the values decrease in the order of 243, 2, 1.

  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 setting key switch 37 is turned on and the power is turned on, the setting value read from the RAM 41c is displayed on the setting value display 24 as a display value, and the setting value can be changed by operating the reset / setting switch 38. Transition to the setting change state. When the reset / setting switch 38 is operated in the setting change state, the display value displayed on the setting value display 24 is updated one by one (when further operation is performed from the setting 6, the display returns to the setting 1). . When the start switch 7 is operated, the display value is determined as the set value. Then, when the setting key switch 37 is turned OFF, the determined display value (setting value) is stored in the RAM 41c of the main control unit 41, and the state shifts to a state in which the game can proceed.

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

  In the slot machine 1 of the present embodiment, when the main CPU 41a detects a voltage drop signal from the power interruption detection circuit 48, a power interruption interrupt process (main) is executed. In the power interruption interrupt processing (main), the register is saved in a stack of a RAM 41c, which will be described later, and data for destructive diagnosis (in this embodiment, 5AH) in which any bit is 1 in the RAM 41c, that is, a specific value other than 0 In addition to storing 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 is 0, and the RAM 41c is stored. 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 main 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 The processing state of the main CPU 41a is restored to the state before the power interruption based on the data stored in the RAM 41c on the condition that the value of the data for use is correct, but the RAM parity is not 0 (in the case of 1) or is destroyed. If the value of the diagnostic data is not correct, it is determined that the RAM is abnormal, and the RAM abnormal error code is set in the register to control the RAM abnormal error state so that the progress of the game is disabled. 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 state described above. It will not be released until

  In this embodiment, all the data stored in the RAM 41c is held by the backup power source even in the event of a power failure, and when the main CPU 41a determines that the data in the RAM 41c is normal when the power is turned on. Although the configuration is such that the control state before power interruption is restored based on the data stored in the RAM 41c, only the data necessary for the restoration of the control state in the event of a power failure is backed up among the data stored in the RAM 41c. It may be configured to return to the control state before power interruption based on the backed up data.

  In addition, when returning to the control state before the power interruption when the power is turned on, it is not necessary to return all the control states to the control state before the power interruption, and the minimum control state that does not disadvantage the player For example, it is not necessary to restore the state of all input ports to the state before power interruption.

  In addition, when the sub CPU 91a detects the voltage drop signal from the power interruption detection circuit 98, the sub CPU 91a also executes a power interruption interrupt process (sub). In the power interruption interrupt processing (sub), the register is saved in a stack of a RAM 91c described later, and destructive diagnosis data in which any bit is 1 is stored in the RAM 91c, and data stored in all areas of the RAM 91c. The RAM parity adjustment data is calculated so that the RAM parity based on 0 becomes 0 and stored in the RAM 91c.

  Then, the sub CPU 91a calculates the RAM parity based on the data stored in all areas of the RAM 91c at the time of activation, and based on the data stored in the RAM 91c on the condition that the RAM parity is 0. The processing state of the sub CPU 91a is restored to the state before the power interruption. If the RAM parity is not 0 (1), it is determined that the RAM is abnormal and the RAM 91c is initialized. In this case, unlike the sub CPU 91a, the execution of the performance is not disabled only by initializing the RAM 91c.

  In this embodiment, all data stored in the RAM 91c is held by the backup power source even during a power failure, and the sub CPU 91a determines that the data in the RAM 91c is normal when the power is turned on. Although the configuration is such that the control state before power interruption is restored based on the data stored in the RAM 91c, only the data necessary for restoration of the control state is backed up in the event of a power failure out of the data stored in the RAM 91c. It may be configured to return to the control state before power interruption based on the backed up data.

  In addition, when returning to the control state before the power interruption when the power is turned on, it is not necessary to return all the control states to the control state before the power interruption, and the minimum control state that does not disadvantage the player It is not necessary to restore the state of the input port or the progress in the middle of the production when it is interrupted. For example, while backing up only data indicating the gaming state such as whether it is in the BB or the normal gaming state, other than the effect corresponding to the gaming state (the effect during the BB during the BB, the normal effect when in the normal gaming state) If a power outage occurs during the execution of a specific production (such as a small role announcement), it will be backed up when the power is turned on instead of resuming the specific production that was being performed at the next power-on. An effect corresponding to the gaming state being played may be executed from the beginning.

  Next, initialization of the RAM 41c of the main control unit 41 will be described. The storage area of the RAM 41c of the main control unit 41 is divided into an important work, a general work, a special work, a set value work, a non-saved work, an unused area, and a stack area.

  The important work is a work in which data that is inconvenient to be initialized at the end of the BB, such as various display devices and LED display data, input / output data of the I / O port 41d, and a game time clock counter, is stored. The general work is a work that stores data that can be initialized at the end of the BB, such as a stop control table, a stop symbol, the number of medals paid out, and the total number of medals paid out in the BB. The special work stores data that is not initialized even before the setting is changed, such as data for transmitting a command to the effect control board 90 and various software random numbers (a random number for determination value addition described later, a random number for changing an initial value). Work. The set value work is a work that stores a set value used when a lottery is performed in the internal lottery process. The unsaved work is a work that holds the state of various switches, and a value is always set regardless of whether or not the data in the RAM 41c is destroyed at the time of activation. The unused area is an unused area in the storage area of the RAM 41c, and is initialized if any one of a plurality of initialization conditions described later is satisfied. The stack area is an area in which data saved from the register of the main CPU 41a is stored, and the unused stack area is established by any one of a plurality of initialization conditions to be described later, like the unused area. In this case, the used stack area is not initialized because the program continues.

  In this embodiment, the main CPU 41a destroys the data in the RAM 41c when a RAM error occurs, when the setting key switch 37 is activated with the setting key switch 37 turned on, when the BB is completed, and when the setting key switch 37 is activated with the setting key switch 37 turned off. Otherwise, when the five initialization conditions at the end of one game are satisfied, five types of initializations with different areas initialized according to each initialization condition are performed.

  Initialization 0 is initialization that is performed when a RAM abnormality error occurs. In initialization 0, all the areas (including the unused area and the unused stack area) of the storage area of the RAM 41c except the used stack area are stored. It is initialized. 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 state. In the initialization 1, a special area in the storage area of the RAM 41c is selected. Areas other than the work, the unsaved work, and the used stack area (including the unused area and the unused stack area) are initialized. Initialization 2 is initialization performed at the end of the BB. 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 this embodiment, initialization 1 is performed before the change of the setting change state. However, the initialization 1 is performed at the end of the setting change state, or both before the change of the setting change state and at the end of the setting change state. Also good. In this case, if the set value work is initialized, the determined set value is lost. Therefore, the initialization of the set value work is not performed in the initialization at the end of the setting change state.

  In the slot machine 1 according to the present embodiment, as described above, the specified number of bets that can be set according to the gaming state is determined, and the specified number of bets determined according to the gaming state is set. It becomes possible to start the game on the condition. In this embodiment, as will be described later, there are a regular bonus (hereinafter referred to as RB) (big bonus (hereinafter referred to as BB)) and a normal gaming state as a gaming state, of which RB (BB) is the number of bets. 2 is defined as the prescribed number of 3 and 3 is defined as the prescribed number of bets in the normal gaming state. For this reason, if the gaming state is RB (BB), the game can be started when the bet number is set to 2, and if the bet number is set to 3 in the normal gaming state, the game is started. It is possible to start. In the present embodiment, all the pay lines L1 to L5 are activated when a specified number of bets corresponding to the gaming state are set, and as RB (BB) All winning lines L1 to L5 are activated when 2 is determined, and all winning lines L1 to L5 are activated when 3 is set as the number of bets in the normal gaming state. Become.

  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). When a combination of symbols called a combination is arranged on the winning line, a winning is achieved. The combination may be a combination of the same symbols or a combination including different symbols. The type of winning combination is determined according to the game state, but it can be roughly divided into a small role with payout of medals and a replay that can start the next game without the need to set the number of bets. There are a game combination and a special combination with a transition 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 a combination of combinations permitted by the flag is completed, and is invalid in a game having a combination of combinations permitted. In other words, once the special combination winning flag is won, even if the combination of the combinations permitted by the flag cannot be made, the winning flag is not invalidated and is carried over to the next game. It becomes.

  As the role in the slot machine 1, as shown in FIG. 6, a big bonus (hereinafter referred to as BB as a big bonus) and a regular bonus (hereinafter referred to as RB as a regular bonus) are used as special roles. Sheets, watermelons, cherries, and bells are replayed as replay players.

  Cherry is awarded when the symbol “white cherry” is derived on any of the winning lines for the right reel in any gaming state, and one medal is paid out in any gaming state. In addition, when the symbol of “white cherry” stops at the upper or lower stage of the right reel, the combination of cherries is aligned on the two winning lines of the winning lines L2, L5 or the winning lines L3, L4. Since winning a cherry on the winning line, two medals will be paid out.

  A watermelon is awarded when a combination of “watermelon-watermelon-watermelon” or “watermelon-watermelon-BAR” is available on any of the winning lines in any gaming state, and 15 RBs (BB). Medals are paid out, and in the normal gaming state, 12 medals are paid out. Bell is awarded when the combination of “Bell-Bell-Bell” is aligned on any of the winning lines in any gaming state, and 15 medals are paid out in RB (BB). Ten medals are paid out.

  Replay is a combination of “Replay-Replay-Replay”, “BAR-Replay-Replay”, or “Black 7-Replay-Replay” in any of the winning lines in the normal gaming state. Wins when you have the right. When the replay wins, no medals are paid out, but the next game can be started without setting the number of wagers again, so that three medals corresponding to the number of wagers that are not required to be set in the next game are paid out. Is essentially the same.

  RB is won when the combination of “net 7-net 7-black 7” is aligned on any of the winning lines in the normal gaming state, and the gaming state shifts to RB. The RB is a gaming state that is advantageous to the player over other gaming states by increasing the winning probability of the small role, particularly the bell, and when the 12 games are digested after the RB starts, or an 8-game winning ( When the type of a combination is allowed), it ends either whichever comes first.

  BB is a combination of “black 7-black 7-black 7”, “net 7-net 7-net 7” or “white 7-white 7-white 7” in any of the winning lines in the normal gaming state. When the combination is complete, a prize is awarded.

  When BB wins, the gaming state shifts to BB and shifts to RB at the same time. When RB ends, if BB has not ended, it shifts to RB again and is controlled repeatedly until BB ends. The That is, during BB, it is always controlled to RB. The BB ends when the total number of medals paid out to the player in the BB exceeds 465. At the end of the BB, the RB is also ended regardless of whether the RB end condition is satisfied.

  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, a random number for internal lottery (an integer from 0 to 65535) is acquired. Then, for each combination determined according to the gaming state and whether or not the special combination is carried over, the acquired random number for internal lottery and the number of judgment values for each combination determined according to the gaming state, the number of bets and the set value Is done according to.

  In the present embodiment, as shown in FIG. 6, the role that is the subject of the internal lottery differs depending on whether the gaming state is the normal gaming state or RB (BB). Further, when the gaming state is the normal gaming state, the role to be subject to the internal lottery varies depending on whether or not the special role is being carried over.

  When the gaming state is the normal gaming state and any special combination is not carried over, BB, RB, replay, watermelon, cherry, and bell are sequentially read out as the target combination of the internal lottery.

  When the gaming state is the normal gaming state and any special combination is carried over, replay, watermelon, cherry, and bell are sequentially read out as the target combinations for the internal lottery.

  When the gaming state is RB, watermelon, cherry, and bell are sequentially read out as the subject combination of the internal lottery.

  In the internal lottery, the number of determination values determined corresponding to the role to be subject to the internal lottery, the current gaming state and the set value are sequentially added to the random number for the internal lottery, and when the result of addition overflows, It is determined that the winning combination has been won. For this reason, a winning combination will be won with a probability (number of determination values / 65536) according to the number of determination values.

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

  The random numbers for the internal lottery are the hard random number latched by the latch circuit 42b of the random number circuit 42 when the operation of the start switch 7 that triggered the internal lottery is detected, and the operation of the start switch 7 And a random number for adding judgment values.

  Specifically, as shown in FIG. 7A, when the start switch 7 is detected to be ON, the hard random number latched from the buffer of the latch circuit 42b is read, and the determination assigned to the special work in the RAM 41c. The determination value addition random number is extracted from the value addition random number counter. Then, a result obtained by adding the read hard random number and the extracted random number for determination value addition is acquired as a random number for internal lottery. Both the hard random number and the decision value addition random number are 16-bit values, and as a result of adding the hard random number and the decision value addition random number, overflow may occur, but in this case, the lower 16 bits of the addition value A value, that is, a remainder obtained by dividing the added value by 65536 is acquired as a random number for internal lottery.

  In the RAM 41c, a determination value addition random number counter for counting a determination value addition random number used when creating a random number for internal lottery and an initial value changing random number used for determining an initial value of the determination value addition random number are stored. An initial value changing random number counter for counting and an initial value storing work for storing initial values of determination value adding random numbers are assigned.

  The determination value addition random number is a value in the range of 0 to 65535, which is the same as the hard random number, and is updated once every time the timer interrupt process (main) is executed four times. As shown in FIG. 7B, a value stored in the determination value addition random number counter is read at the timing of the update time, and a constant value that is relatively prime to the total number of decision value addition random numbers (65536). (In this embodiment, 19463) is added, and the remainder obtained by dividing the total number of decision value addition random numbers (65536) from the addition value, that is, the lower 16 bits of the addition value is used as a new decision value addition random number. It is updated by storing it in a random number counter for determination value addition.

  In addition, when the new determination value addition random number obtained by the calculation matches the initial value storage work value, that is, when the determination value addition random number makes one round, the value of the initial value change random number counter, that is, By storing the initial value changing random number at that time as a new decision value adding random number in the decision value adding random number counter, the initial value of the decision value adding random number is changed every round. Yes. The initial value of the random number for determination value addition is stored in the initial value storage work, so that the starting point of the cycle of the random number for determination value addition can be specified.

  The initial value changing random number is a value in the range of 0 to 65535, which is the same as the determination value adding random number, and is updated once every time the timer interrupt process (main) is executed four times. The basic process is updated every loop during the period waiting for the start of the game and the period waiting for the stop of all reels after the game starts. The initial value changing random number is incremented by 1 each time it is updated, and returns to 0 when it counts up to 65535.

  The determination value addition random number and the initial value change random number are both random numbers generated by software. Hereinafter, the determination value addition random number and the initial value change random number are also referred to as software random numbers.

  When the power is turned on, when returning to the control state before power interruption, all of the initial values of the judgment value addition random number, initial value change random number, and judgment value addition random number before power interruption are maintained. The update of the random number for adding the judgment value and the random number for changing the initial value is started from the state before the power interruption. After that, when the determination value addition random number reaches the initial value, it is determined that the determination value addition random number has made one round, and the initial value change random number becomes the initial value of the new determination value addition random number. Update of the random number for determination value addition of the cycle starts, and thereafter, every time the random number for determination value addition makes one round, the initial value of the random number for determination value addition is changed by the initial value changing random number at that time. It will be.

  When the setting key switch 37 is in an ON state when the power is turned on, and when shifting to the setting change state, all the areas of the RAM 41c except the special work, the non-saved work and the used stack area are initialized, The control state before disconnection is initialized, but since the random number counter for determination value addition and the random number counter for initial value change are assigned to special work, the random number for determination value addition before disconnection and the initial value The random number for value change is maintained without being initialized. In this case, the determination value addition random number and the initial value change random number maintained before the power interruption are added, and the addition value is added to the total number of decision value addition random numbers (initial value change random numbers) (65536). ), That is, the lower 16 bits of the addition value are set as the initial value of the decision value addition random number, the initial value change random number, and the decision value addition random number. Start updating the random number for value change. After that, when the decision value addition random number reaches the initial value, that is, the decision value addition random number is obtained by calculation using the decision value addition random number and the initial value change random number before power interruption when the power is turned on. Is reached, the decision value addition random number is judged to have made one round, the initial value change random number becomes the initial value of the new decision value addition random number, and the update of the decision value addition random number in a new cycle starts. Thereafter, every time the determination value addition random number makes one round, the initial value of the determination value addition random number is changed by the initial value change random number at that time.

  When the setting key switch 37 is in an OFF state when the power is turned on, and the data in the RAM 41c is not normal and cannot be restored to the control state before the power interruption, all the areas of the RAM 41c except the used stack area are stored. It is initialized and the control state before power interruption is initialized. At this time, since the special work to which the determination value addition random number counter and the initial value change random number counter are assigned is also initialized, the determination value addition random number and the initial value change random number before power interruption are also initialized. It will end up. In this case, a value based on the chip ID stored in the nonvolatile memory area of the main control unit 41 is set as an initial value of a determination value addition random number, an initial value change random number, and a determination value addition random number, The update of the random number for adding the judgment value and the random number for changing the initial value is started. The chip ID is a 4-byte value that is individually assigned when the main control unit 41 is manufactured, and among these, the lower 2 bytes are used as the initial value of the determination value addition random number, the initial value change random number, and the determination value addition random number. Use for value. Thereafter, when the determination value addition random number reaches the initial value, that is, when the determination value addition random number reaches a value based on the chip ID set at the time of power-on, the determination value addition random number makes one round. Thus, the initial value change random number becomes the initial value of the new determination value addition random number, and the update of the new determination value addition random number starts, and thereafter, the determination value addition random number makes one round. Every time, the initial value of the determination value adding random number is changed by the initial value changing random number at that time.

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

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

  In the table index, an index that indicates the start address of the area in which the data for table creation is stored, from the reference address 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) Differences up to the address where the data is stored are 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. Even when the winning combinations are different, when the same control is applied, the same address is stored as the index data. In such a case, the same table creation data is referred to. Thus, a stop control table is created.

  The table creation data includes a stop control table indicating the number of sliding frames according to the stop operation position, and an address of the stop control table to be referred to according to the reel stop status.

  The stop control table referred to according to the reel stop status is whether all reels are rotating, only the left reel is stopped, only the middle reel is stopped, only the right reel is stopped, It may vary depending on whether the middle reel is stopped, the left and right reels are stopped, the middle and right reels are stopped, and if any reel is stopped, stop Since there may be differences depending on the stop position of the reels already completed, the address of the stop control table to be referenced for each situation is registered for each rotating reel, and based on the top address of the table creation data, It is possible to specify the address of the stop control table that should be referred to according to the status of each, and it is necessary according to each status from this specified address. And to be able to identify the stop control table. Even when the reel stop status and the stopped position of the stopped reel are different, when the same stop control table is applied, the same address may be registered as the address of the stop control table. In such a case, the same stop control table is referred to.

  The stop control table is data that can specify the number of sliding frames for each timing when the stop operation is performed. In this embodiment, stepping motors that make one turn at a cycle of 168 steps (0 to 167) are used for the reel motors 32L, 32C, and 32R. That is, when the reel motors 32L, 32C, and 32R are driven for 168 steps, the reels 2L, 2C, and 2R make one round. Then, 21 areas (frames) divided every 16 steps (the number of steps that one symbol moves) are defined for one reel, and these areas are areas 0 to 20 from the reel reference position. A number is assigned. On the other hand, the number of symbols arranged on one reel is 21, and symbol numbers 0 to 20 from the reel reference position are assigned to symbols on each reel, so symbols 0 to 20 are assigned to each reel. , Area numbers 0 to 20 are assigned in order. In the stop control table, the number of sliding symbols for each area number is compressed and stored according to a predetermined rule, and the number of sliding symbols for each area number can be acquired by expanding the stop control table. Yes.

  As described above, the stop control table created by referring to the table index and the table creation data corresponds to the area number, and the area corresponding to each area number is the stop reference position (in this embodiment, the perspective window 3). Sliding frame when an operation of the stop switches 8L, 8C, 8R is detected at a timing (a timing in which the number of steps from the reel reference position is included in the range of the number of steps of each region number). It is a table with each number set.

  Next, the procedure for creating the stop control table will be described. First, at the start of reel rotation, the top address of the table creation data corresponding to the internal winning state of the game is acquired. Specifically, the table index is first referred to, index data corresponding to the internal winning state is obtained, table creation data is identified based on the obtained index data, and all reels are identified from the identified table creation data. The address of the stop control table for each reel corresponding to the state of rotation is acquired, and the stop control table for each reel stored at the acquired address is expanded to generate a stop control table for all reels.

  Further, when any one reel stops or any two reels stop, the index data acquired at the start of reel rotation, that is, the top address of the table creation data corresponding to the internal winning state of the game The table creation data is identified based on the table creation data, and the stop control table address of the unreacted reel corresponding to the stopped reel and the area number of the stop position of the reel is obtained from the identified table creation data. The stop control table for each stored reel is expanded to create a stop control table for the unstopped reels.

  Next, when the main CPU 41a effectively detects any one of the stop switches 8L, 8C, and 8R corresponding to the rotating reel, the control when the display result is derived to the corresponding reel will be described. When one of the stop switches 8L, 8C, and 8R corresponding to the rotating reel is effectively detected, the stop operation position area is determined based on the number of steps from the reel reference position when the stop operation is detected. The number is specified, the stop control table of the reel where the stop operation is detected is referred, and the number of sliding symbols corresponding to the area number of the specified stop operation position is acquired. Then, control is performed to rotate and stop the reel by the number of acquired sliding frames. Specifically, from the number of steps from the reel reference position at the time when the stop operation is detected, the number of steps from the acquired number of sliding frames to the stop is calculated, and the reel is rotated and stopped by the calculated number of steps. Take control. As a result, the area corresponding to the area number that is the stop position ahead of the number of sliding frames from the area corresponding to the area number of the stop operation position where the stop operation is detected is the stop reference position (in this embodiment, the perspective window 3 It will stop in the lower symbol area).

  In the table index of this embodiment, only one address is stored as index data corresponding to one internal winning state in one gaming state, and further, one table creation data includes one reel. Only one address is stored as the address of the storage area of the stop control table corresponding to the stop status (and the stop position of the stopped reel). In other words, table creation data corresponding to one internal winning state in one gaming state and stop control tables corresponding to reel stop states (and stopped positions of stopped reels) are uniquely determined. The stop control table created with reference to is unique for one internal winning state in one gaming state and the reel stop status (and the stop position of the stopped reel). Therefore, when all of the gaming state, the internal winning state, and the reel stop status (and the stop position of the stopped reel) are the same, the reel is based on the same stop control table, that is, the same control pattern. The stop control is performed.

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

  In this embodiment, when any of the winning combinations is won, the winning combination is drawn to the maximum in the range of 4 frames on the winning line, and the non-winning winning combination is drawn so that it is not aligned on the winning line. A stop control table with a defined number of frames is created and reel stop control is performed. If no winning combination is selected, a stop control table with a determined number of sliding symbols that do not have any combination And stop control of the reel. As a result, when a stop operation is performed, if the winning combination can be stopped on the winning line in the drawing range of up to 4 frames, the control is performed so that the winning combination is stopped. The combination that has not been performed will be controlled to be stopped in a drawing range of a maximum of 4 frames.

  When a special role and a small role are elected at the same time, such as when a special role is elected while the special role has been carried over from before the previous game, the winning small role is the maximum in the range of 4 frames on the winning line. The number of sliding frames is fixed so that it can be drawn to the limit, and for the stop operation position where the selected small role cannot be drawn in the range of up to 4 frames in the winning line, the winning special role is in the range of 4 frames in the winning line Then, a stop control table in which the number of sliding frames is determined so as to be pulled in as much as possible is created, and reel stop control is performed. As a result, when a stop operation is performed, if it is possible to stop all the small roles that have been selected in the drawing range of up to 4 frames on the winning line and stop them, control is performed so that the winning combination is stopped. If you can't draw a small role that has been won in the drawing range of up to 4 frames on the line, if you can stop with a special role that has been won in the drawing range of up to 4 frames on the winning line, A control is performed to stop them in a uniform manner, and a winning combination that has not been won will be controlled to be stopped within a 4-frame pull-in range. That is, in such a case, priority is given to the control for aligning the small combination on the winning line over the special combination, and the special combination can be won only when the small combination cannot be drawn. When a special combination and a small combination can be withdrawn at the same time, only the small combination is drawn in, and the small combination is not aligned on the winning line at the same time as the special combination.

  In this example, when a special role is elected while the special role has been carried over from before the previous game, or when a special role and a small role are simultaneously elected, the special role and the small role are won simultaneously. If the selected special role is given priority over the selected special role, the special role is controlled on the winning line only when the small role cannot be withdrawn. When winning simultaneously, priority is given to the control for aligning the special role on the winning line over the small role, and the control for aligning the small role on the winning line may be performed only when the special role cannot be drawn.

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

  In this embodiment, after the rotation of the reels 2L, 2C, and 2R is started, the main CPU 41a continues to rotate the reels for which the stop operation has not been detected until the operation of the stop switches 8L, 8C, and 8R is detected. On the condition that the operation of the stop switches 8L, 8C, 8R is detected, control is performed to stop the display result on the corresponding reel. Even if the reel rotation temporarily stops due to the occurrence of a reel rotation error, the stop operation is still detected until the operation of the stop switches 8L, 8C, and 8R is detected after the reel rotation is restarted. Control is performed to stop the display result of the corresponding reels on the condition that the rotation of the reels that have not been continued is continued and the operation of the stop switches 8L, 8C, and 8R is detected.

  In this embodiment, control is performed to stop the display result on the corresponding reel on condition that the operation of the stop switches 8L, 8C, and 8R is detected. However, the rotation of the reel is started. When a predetermined automatic stop time has elapsed, even if the reel stop operation is not performed, it is assumed that the stop operation has been performed, and automatic stop control is performed to automatically stop each reel. May be. In this case, since the reels are stopped without the player's operation, it is preferable to derive a display result that does not constitute any combination even if any combination is won.

  Next, commands that the main CPU 41a transmits to the effect control board 90 will be described.

  In the present embodiment, the main CPU 41a sends a BET command, a credit 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 game state command to the effect control board 90. A plurality of types of commands including a standby command, an abort command, an error command, a return command, a setting start command, a confirmation start command, a confirmation end command, and an operation detection command.

  These commands are composed of 1-byte type data indicating the type of command and 1-byte extension data indicating the content of the command, and the sub CPU 91a can determine the type of command from the type data.

  The BET command is a command that can specify the number of inserted medals, that is, the number of medals used to set the bet number, and is a state from the end of the game (after setting change) to the start of the game. Sent when a medal is inserted or the bet number is set by operating the single BET switch 5 or the MAXBET switch 6 in a state where is not set. Further, since the BET command is transmitted when the betting number setting operation is performed, it is possible to specify that the betting number setting operation has been performed by receiving the BET command.

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

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

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

  The reel stop command is a command that can specify whether the reel to be stopped is the left reel, the middle reel, or the right reel, the area number of the corresponding reel stop operation position, and the area number of the corresponding reel stop position. And is transmitted each time stop control is performed in accordance with the stop operation of each reel. Since the reel stop command is transmitted when the stop switches 8L, 8C, and 8R are operated, it is possible to specify that the stop switches 8L, 8C, and 8R are operated by receiving the reel stop command. .

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

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

  The game state command is a command that can specify the game state of the next game, and is transmitted when the setting change state ends and when the game ends.

  The standby command is a command indicating a transition to the standby state, and after one game is over, a credit (which was used for setting the bet number) is set when the transition to the standby state is made after a predetermined time without setting the bet number. (Including medals) is sent out after the medal payout is completed and the payout end command is sent.

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

  An error command is a command that indicates the occurrence or cancellation of an error condition and the type of error condition. When an error is determined and controlled to an error condition, an error command indicating the occurrence and type of the error condition is sent and reset. When the error state is canceled after the operation is performed, an error command indicating the cancellation of the error state is transmitted.

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

  The setting start command is a command indicating the start of the setting change state, and is transmitted when shifting to the setting change state. Further, since the control state of the main CPU 41a is initialized with the transition to the setting change state, it is possible to specify that the control state of the main CPU 41a has been initialized by the setting start command.

  The confirmation start command is a command indicating the start of the setting confirmation state, and is transmitted when shifting to the setting confirmation state. The confirmation end command is a command indicating the end of the setting confirmation state, and is transmitted when the setting confirmation state ends.

  The operation detection command is a command indicating the detection state (ON / OFF) of the operation switches (one-sheet BET switch 5, MAXBET switch 6, start switch 7, stop switches 8L, 8C, 8R), and is transmitted at regular intervals. Is done.

  Among these commands, a setting start command, an error command indicating a RAM abnormality, and a return command are generated at a stage before an interrupt is permitted in the startup process and stored in a specific command transmission buffer assigned to a special work in the RAM 41c. And sent immediately.

  Commands other than a setting start command, an error command indicating a RAM abnormality, a return command, and an operation detection command are generated according to the progress of the game in the game process, and are temporarily stored in a normal command transmission buffer provided in a special work in the RAM 41c. Stored and transmitted in the command transmission process executed during the timer interrupt process (main).

  The operation detection command is generated every time the command transmission process is executed five times, stored in the aforementioned specific command transmission buffer, and immediately transmitted. In addition, when the operation detection command transmission time is reached with the unsent command stored in the normal command transmission buffer, priority is given to the transmission of the operation detection command and the normal command transmission buffer stores it. The untransmitted command is transmitted in the next command transmission process, and a plurality of commands are not transmitted in one command transmission process.

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

  The sub CPU 91a executes a command reception interrupt process when a strobe signal indicating the transmission of a command from the main CPU 41a is input. In the command reception interrupt process, the command acquired from the command transmission line is stored in the reception buffer provided in the RAM 91c.

  In the timer interrupt process (sub), the sub CPU 91a determines whether or not an unprocessed command is stored in the reception buffer. If an unprocessed command is stored, the sub CPU 91a is the earliest stage. Based on the received command, the control pattern table stored in the ROM 91b is referred to. Based on the control contents registered in the control pattern table, various effects such as the liquid crystal display 51, the effect LED 52, the speakers 53 and 54, the reel LED 55, etc. Control the output of the device.

  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 sub CPU 91a receives the command, the sub CPU 91a, among the control patterns registered corresponding to the effect patterns set in the RAM 91c in the game of the control pattern table, With reference to the control pattern corresponding to the type of command received, output control of the rendering device is performed based on the control pattern. Thereby, the production according to the production pattern and the progress of the game is executed.

  If the sub CPU 91a receives a new command during execution of an effect triggered by the reception of a certain command, the sub CPU 91a stops the effect based on the control pattern being executed, and responds to the newly received command. An effect based on the control pattern is executed. In other words, even if the production is not finished to the end, when a new command is received, the production that was being executed is canceled and a new command is received unless the received new command is not a command that triggers a new production. An effect based on the command is executed.

  In particular, in this embodiment, when an operation for setting the number of bets is performed during execution of an effect, that is, when the sub CPU 91a receives a BET command indicating that the number of bets has been set, the effect being executed is canceled. It is supposed to be. For this reason, if the player wants to proceed to the next game rather than seeing the production to the end, the production is canceled and the next game can be started. There is no. Further, when a credit or bet amount adjustment operation is performed during the performance, that is, after the sub CPU 91a receives a game state command indicating the end of the game, and before receiving an internal winning command indicating the start of the game. When the payout start command is received, the performance being executed is stopped. Credits and bets are settled when the game is terminated. In such a case, by terminating the performance that is being executed, there is an intention to end the game, but the performance continues unnecessarily. It is designed not to be overwhelmed.

  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 sub CPU 91a receives the internal winning command, it is registered in the effect table according to the result of the internal lottery indicated by the internal winning command. Is selected from a plurality of types of effect patterns according to the selection rate, and the selected effect pattern is set in the RAM 91c as the effect pattern of the game, Even if the same command is received, a different control pattern is selected depending on the effect pattern selected when the internal winning command is received. As a result, different effects may be performed depending on the effect pattern.

  Next, various control contents executed by the main 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 main CPU 41a performs a startup process (main) shown in the flowchart of FIG. Since the reset signal is a signal that is output when the power is turned on and when the operation of the main control unit 41 is stagnant, the activation process (main) is performed when the main CPU 41a is activated when the power is turned on and when the main CPU 41a malfunctions. This process is performed when restarting.

  In the startup process (main), 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 the voltage drop signal is input. Whether or not the voltage is stable (Sa2), and if the voltage drop signal is input, any of the other than the determination of whether or not the voltage drop signal is input The process shifts to a loop process in which no process is performed.

  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). 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 (Sa4), the RAM parity of all storage areas (including the unused area and the unused stack area) of the RAM 41c is calculated (Sa5), the abort switch 36a, and the automatic settlement switch 36b. And the valid / invalid of the stop function and the automatic settlement function are set in a specific register of the main CPU 41a (Sa6).

  Next, it is determined whether or not the RAM parity calculated in step Sa5 is 0 (Sa7). If the power interruption interrupt processing (main) is normally performed, the RAM parity should be 0. If the RAM parity is not 0 in the step of Sa7, the data stored in the RAM 41c is not normal. In this case, after executing initialization 0 that initializes all the storage areas except the used stack area in the storage area of the RAM 41c (Sa17), the value of the lower 2 bytes of the chip ID is added to the determination value. Random number counter, initial value changing random number counter, and initial value storing work are set (Sa18), and it is determined whether or not the setting key switch 37 is ON, that is, whether or not an operation for shifting to the setting changing state is performed. (Sa19) If the setting key switch 37 is ON, the interruption is permitted (Sa16), and the process shifts to the setting change process, that is, the setting change state.

  If the setting key switch 37 is OFF in step Sa19, an error code indicating RAM abnormality is set in the register (Sa20), interrupt is permitted (Sa21), and the process proceeds to error processing, that is, RAM abnormality error state. .

  If the RAM parity is 0 in step Sa7, it is further determined whether or not the destructive diagnosis data is normal (Sa8). If power interruption interrupt processing (main) is performed normally, the data for destruction diagnosis should be set. If the data for destruction diagnosis is not normal in step Sa8 (data for destruction diagnosis is power interruption) Since the data in the RAM 41c is not normal even in cases other than 5A (H) stored at the time, the process proceeds to step Sa17 to execute initialization 0, and the value of the lower 2 bytes of the chip ID in step Sa18 Are respectively set to the decision value addition random number counter, the initial value change random number counter, and the initial value storage work. If the setting key switch 37 is ON in step Sa19, then interrupt is permitted (Sa16). If the setting key switch 37 is OFF when the setting key switch 37 is turned off, an error code setting indicating a RAM abnormality (Sa20) is permitted and an interrupt is permitted (Sa 1), the process proceeds to error processing.

  If it is determined in step Sa8 that the destructive diagnosis data is normal, the data in the RAM 41c is normal, and therefore the destructive diagnosis data is cleared (Sa9). After performing initialization 3 for initializing the used stack area (Sa10), it is determined whether the setting key switch 37 is ON (Sa11). If the setting key switch 37 is ON, the process proceeds to step Sa14. The initialization value that initializes all storage areas in the storage area of the RAM 41c except for the special work, the non-saved work, and the in-use stack area is executed. In the initialization 1, the determination value that is maintained without being initialized. The addition random number and the initial value changing random number are added, and the remainder obtained by dividing the addition value by 65536, that is, the lower 16 bits of the addition value is used as the determination value addition random number. Counter, the initial value changes random number counter, and set to the initial value storage work (Sa15), allow interruption (Sa16), the process proceeds to the setting change processing.

  If the setting key switch 37 is OFF in the step of Sa11, each register is restored to the state before power interruption, that is, stored in the stack (Sa12), interrupt is permitted (Sa13), power interruption Return to the process that was running last.

  FIG. 9 is a flowchart showing the control contents of error processing executed by the main CPU 41a.

  In the error processing, first, the current display state of the game auxiliary display 12 is saved in the stack (Sb1), the error code stored in the register is displayed on the game auxiliary display 12 (Sb2), and the error code is stored in the RAM. It is determined whether or not the error code indicates an abnormal error (Sb3). If the error code indicates a RAM abnormal error, the process proceeds to a loop process that does not perform any process.

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

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

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

  FIG. 10 is a flowchart showing the control content of the setting change process executed by the main CPU 41a.

  In the setting change process, first, the setting value stored in the setting value work of the RAM 41c is read out, and the read value is set as the display value (Sc1). Whether the display value is outside the settable range (1 to 6) or not. (Sc2), if the display value is within the settable range, the process proceeds to step Sc4. If the display value is outside the settable range, the display value is corrected to 1, and the process proceeds to step Sc5.

  In the step of Sc5, after the display value is displayed on the set value display 24, the operation waits for detection of the operation of the reset / setting switch 38 and the start switch 7 (Sc5, Sc6). In the step of Sc5, the reset / setting switch When 38 on is detected, the display value is incremented by 1 (Sc7), and the process returns to the Sc2 step.

  If the start switch 7 is detected to be on in the step of Sc6, the value displayed on the set value display 24 is updated to 0 (Sc8) and waits until the setting key switch 37 is turned off. (Sc9).

  If it is determined in step Sc9 that the setting key switch 37 is OFF, the display value is stored in the setting value work (Sc10), and the process proceeds to game processing.

  FIG. 11 is a flowchart showing the control contents of the game process executed by the main 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 a bet number can be set, and a process for starting a game when a specified number of bets is set according to the gaming state and the start switch 7 is operated is executed. .

  In the internal lottery process in step Sd2, a process is performed for determining whether or not the winning of each combination described above is allowed based on the random value for internal lottery created simultaneously with the detection of the start switch 7 in the step Sd1. . 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 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 the game process, a command is generated in accordance with the progress control of the game and set in the normal command transmission buffer, so that the command set to the sub CPU 91a is transmitted in the subsequent timer interrupt process (main). It has come to be.

  12 to 14 are flowcharts showing the control contents of the BET process executed by the main CPU 41a in step Sd1.

  In the BET process, first, the value of the BET counter in which the value of the betting number is stored in the RAM 41c is cleared (Se1), and a prescribed number (3 regardless of the gaming state in this embodiment) is set in the RAM 41c. Then, based on whether or not the replay game flag indicating that it is a replay game is set in the RAM 41c, it is determined whether or not the game is a replay game (Se3).

  If it is determined in step Se3 that the game is a replay game, the value of the BET counter is incremented by 1 (Se4), the specified number of bets set in the RAM 41c is referred to, and the value of the BET counter is It is determined whether or not the number is a prescribed number (Se5), and if the value of the BET counter is not the prescribed number, the process returns to the step of Se4. The RAM 41c is set (Se6), and the process proceeds to the Se8 step.

  If it is determined in step Se3 that the game is not a replay game, settings before waiting to be made are performed (Se7), and the process proceeds to step Se8. In the setting before waiting for insertion, the insertion disable flag set in the RAM 41c is cleared and the detection of the single BET switch 5, the MAXBET switch 6, the start switch 7, and the checkout switch 10 is enabled, that is, involved in the progress control of the game. State

  In step Se8, after interrupting is prohibited (Se8), the initial value changing random number is updated (Se9). In step Se9, 1 is added to the value of the initial value changing random number counter. If the value after the addition overflows, the value of the initial value changing counter is cleared and returned to 0. After the Se9 step, the interrupt prohibited in the Se8 step is permitted again (Se10), and the process proceeds to the Se11 step.

  In step Se11, it is determined whether or not an error code is set in the register, that is, whether or not an error is detected. If an error code is set, the process proceeds to error processing shown in FIG.

  If no error code is set in the step of Se11, it is determined whether or not a medal can be inserted based on whether or not the insertion prohibition flag is set in the RAM 41c (Se12). When it is determined in step Se12 that the medal can be inserted, the flow path switching solenoid 30 is turned on, and the medal can be inserted using the medal flow path as a path on the hopper tank side. (Se13), the process proceeds to the step of Se15, and if it is determined that the medal cannot be inserted, the flow path switching solenoid 30 is set to the off state, and the medal flow path is the path on the medal payout exit 9 side. As a result, the insertion of a new medal is prohibited (Se14), and the process proceeds to Step Se15.

  In the step of Se15, it is determined whether or not the setting key switch 37 is on. If the setting key switch 37 is on, it is determined whether or not the value of the BET counter is 0 (Se16). If the value of the BET counter is 0 in the step Se16, the process proceeds to the setting confirmation process, that is, the setting confirmation state (Se17). After the setting confirmation process is completed, the process returns to the step Se8.

  If the setting key switch 37 is not on in step Se15 or if the value of the BET counter is not 0 in step Se16, the process proceeds to step Se18, and whether or not the inserted medal sensor 31 has detected passage of the inserted medal. That is, it is determined whether or not there is a inserted medal flag indicating that the passage of the inserted medal is detected. If the passage of the inserted medal is not detected in the step of Se18, the process proceeds to the step of Se26, and if the passage of the inserted medal is detected, the inserted medal flag is cleared (Se19), and the non-insertable flag is set in the RAM 41c. Whether or not a medal can be inserted is determined based on whether or not a medal can be inserted (Se20). If the medal cannot be inserted, the process proceeds to step Se26.

  If the medal can be inserted in the step of Se20, the prescribed number of bets set in the RAM 41c is referred to determine whether the value of the BET counter is the prescribed number (Se21) and the BET counter If the value is not the specified number, 1 is added to the value of the BET counter (Se22), and the process returns to the Se8 step.

  If the value of the BET counter is the prescribed number in the step of Se21, 1 is added to the value of the credit counter in which the credit value is stored in the RAM 41c (Se23), and whether or not the value of the credit counter is 50 which is the upper limit value. If the value of the credit counter is not 50, the process returns to the step of Se8. If the value of the credit counter is 50, the insertion impossible flag is set in the RAM 41c (Se25), and the process returns to the step of Se8. .

  In step Se26, it is determined whether an operation of the start switch 7 is detected. If the operation of the start switch 7 is not detected in the step of Se26, the process proceeds to the step of Se32, and if the operation of the start switch 7 is detected, the specified number of bets set in the RAM 41c is referred to and the BET counter It is determined whether or not the value is a specified number (Se27).

  If the value of the BET counter is not a prescribed number in the step of Se27, the process returns to the step of Se8. If the value of the BET counter is a prescribed number, the judgment value is added to the hard random number latched by the latch circuit 42b when the start switch 7 is detected. The random numbers for use are added (Se28), and the lower 16-bit value of the added value is acquired as a random number for internal lottery, and is set as a random value acquisition work assigned to the RAM 41c (Se29). As a result, the hard random number obtained when the start switch 7 is operated and the random number for determination value addition are added to the random value acquisition work, and the remainder obtained by dividing the added value by 65536 is set as a random number for internal lottery. The Rukoto.

  After the step of Se29, the insertion impossible flag is set in the RAM 41c, the flow path switching solenoid 30 is turned off, and the insertion of a new medal is prohibited by using the medal flow path as a path on the medal payout exit 9 side (Se30). ), The setting at the start of the game is performed (Se31). Then, after the step of Se31, the BET process is terminated and the process returns to the flowchart of FIG.

  In step Se32, it is determined whether or not an operation of the single BET switch 5 is detected. If the operation of the single BET switch 5 is not detected in the step of Se32, the process proceeds to the step of Se37, and if the operation of the single BET switch 5 is detected, the specified number of bets set in the RAM 41c is referred to. Then, it is determined whether or not the value of the BET counter is a specified number (Se33). If the value of the BET counter is a specified number in the step of Se33, the process returns to the step of Se8. If the value of the BET counter is not the specified number, it is determined whether the value of the credit counter is 0 (Se34), If the counter value is 0, the process returns to the Se8 step. If the value of the credit counter is not 0 in the step of Se34, 1 is subtracted from the value of the credit counter (Se35), 1 is added to the value of the BET counter (Se36), and the process returns to the step of Se8.

  In step Se37, it is determined whether or not an operation of the MAXBET switch 6 is detected. If the operation of the MAXBET switch 6 is not detected in the step of Se37, the process proceeds to the step of Se42, and if the operation of the MAXBET switch 6 is detected, the specified number of bets set in the RAM 41c is referred to, and the BET counter It is determined whether or not the value is a specified number (Se38). If the value of the BET counter is the specified number in the step of Se38, the process returns to the step of Se8, and if the value of the BET counter is not the specified number, it is determined whether or not the value of the credit counter is 0 (Se39), If the value of the credit counter is 0, the process returns to the Se8 step. If the value of the credit counter is not 0 in the step of Se39, the value of the credit counter is decremented by 1 (Se40), the value of the BET counter is incremented by 1 (Se41), and the process returns to the step of Se38.

  In the step of Se42, it is determined whether or not an operation of the settlement switch 10 is detected. If the operation of the settlement switch 10 is not detected in the step of Se42, the process returns to the step of Se8, and if the operation of the settlement switch 10 is detected, the operation is based on whether or not the replay game flag is set in the RAM 41c. It is determined whether or not the game is a replay game (Se43). If the game is a replay game, the process returns to step Se8. If the game is not a replay game in the step of Se43, it is determined whether or not the value of the BET counter is 0 (Se44). If the value of the BET counter is 0, the process proceeds to the step of Se46, and the value of the BET counter is 0. Otherwise, a bet amount settlement flag indicating that the already set bet amount is to be settled is set in the RAM 41c (Se45), and the process proceeds to Step Se46. In step Se46, the hopper motor 34b is driven to pay out medals corresponding to the value stored in the credit counter or BET counter, that is, medals stored as credits or medals used for setting the number of wagers. Checkout process is performed to control the return. Then, after the settlement process in the step of Se46, the input impossible flag set in the RAM 41c is cleared (Se47), and the process returns to the step of Se8.

  FIG. 15 is a flowchart showing the control contents of the reel rotation process executed by the main CPU 41a in step Sd3.

  In the reel rotation process, first, it is determined whether or not a wait time (about 4.1 seconds in this embodiment) has elapsed since the reel rotation start time of the previous game (Si1), and the wait time must have elapsed. For example, it waits until the wait time elapses.

  If the wait time has elapsed in the Si1 step, a new wait time is set (Si2).

  Next, the setting at the start of the rotation of the reel motor is performed, and the rotation of the reel is started (Si3). Then, a sliding frame number setting process is performed for setting the number of sliding frames for each stop operation position for each reel being rotated (Si4), and the setting at the completion of stop preparation is performed (Si5). As a result, the stop operation can be validated, and then the stop operation becomes valid when the constant speed rotation of the reel is detected in the origin interruption process of the timer interrupt process (main). .

  Next, after prohibiting interruption (Si6), the initial value changing random number is updated (Si7). In the step of Si7, 1 is added to the value of the initial value changing random number counter, and when the value after addition overflows, the value of the initial value changing counter is cleared and returned to 0. After the Si7 step, the interrupt prohibited in the Si6 step is permitted again (Si8), and the process proceeds to the Si9 step.

  In step Si9, it is determined whether any stop switch operation is detected. If no stop switch operation is detected, a reel rotation error (reel reference position by the reel sensor 33 for a certain period or more) is detected. It is determined whether or not a reel rotation error has occurred. Further, if a reel rotation error has not occurred, an insertion error (except for a period during which medal insertion is permitted) Whether or not a medal insertion is detected) and a payout error (an error determined when a medal payout is detected outside the period during which medal payout is permitted). It is determined whether or not it has occurred (Si11, Si12), and if any error occurrence is not determined in the steps of Si10 to Si12, Back to i6 of step.

  If it is determined that an insertion error has occurred in the Si11 step, or if a payout error is determined in the Si12 step, an error code indicating the insertion / discharge error during reel rotation is set in the register (Si13). ), Returning to the Si6 step. If an error code is set here, the process proceeds to error processing in the BET processing of the next game.

  When it is determined in step Si10 that a reel rotation error has occurred, an error code indicating a reel rotation error is set in the register (Si14), all reels are stopped (Si15), and the process is shown in FIG. The process proceeds to error processing (Si13). When the error is released, the process returns to the Si3 step again and the reel rotation is resumed.

  If any stop switch operation is detected in the step of Si9, the number of steps from the reel reference position at that time in the reel motor corresponding to the stop switch in which the operation is detected (stop operation position and Is obtained and set to the work corresponding to the stop reel (Si17), and then waits until the rotation of the reel corresponding to the stop operation stops (Si18).

  Then, when the rotation of the reels corresponding to the stop operation is stopped, it is determined whether or not all the reels are stopped (Si19). If all the reels are not stopped, the process returns to the Si4 step, and all the reels are If it is stopped, the reel rotation process is terminated and the process returns to the flowchart of FIG.

  FIGS. 16 and 17 are flowcharts showing the control contents of the timer interrupt process (main) executed by the main CPU 41a by interrupting the start-up process and the game process in response to the occurrence of the interrupt 3, that is, at an interval of 0.56 ms. is there.

  In the timer interrupt process (main), interrupts are first prohibited (Sk1). That is, the execution of another interrupt process during the execution of the timer interrupt process (main) is prohibited. Then, after saving the register in use to the stack area (Sk2), port input processing for inputting detection data of various switches from the input port is performed (Sk3).

  Next, the branch counter for identifying the timer interrupt to be executed in the timer interrupt process (main) is advanced by 1 from the four types of timer interrupts 1 to 4 (Sk4). In the step of Sk4, 1 is added when the branch counter value is 0 to 2, and is updated to 0 when the counter value is 3. That is, the branch counter value loops in the order of 0 → 1 → 2 → 3 → 0... Each time the timer interrupt process (main) is executed.

  Next, the branch counter value is referenced to determine whether it is 2 or 3, that is, timer interrupt 3 or timer interrupt 4 (Sk5). If it is not timer interrupt 3 or timer interrupt 4, that is, timer interrupt In the case of 1 or timer interrupt 2, it is checked whether the reel motors 32L, 32C, 32R are started or whether they are rotating at a constant speed, and whether the reel motors 32L, 32C, 32R are started or are rotating at a constant speed. For example, the motor phase signal output process for outputting the phase signal data changed in the motor step process of Sk9 described later and the phase signal data changed in the final stop process of Sk25 described later is executed (Sk6).

  Next, referring to the branch counter value, it is determined whether or not it is 1, that is, timer interrupt 2 (Sk7). If it is not timer interrupt 2, that is, timer interrupt 1, reel motor Reel starting process (Sk8) for controlling the step time interval when starting 32L, 32C, 32R, motor step process (Sk9) for changing phase signal data of the reel motors 32L, 32C, 32R, reel motors 32L, 32C After the stop of 32R, motor phase signal standby processing (Sk10) for changing the phase signal to single-phase excitation after a lapse of a certain time is sequentially executed, and then the register saved in the stack area at Sk2 is restored (Sk20). The interrupt prohibited in the step is permitted (Sk21), and the process returns to the state before the interrupt.

  Further, in the case of timer interrupt 2 in the step of Sk7, LED dynamic display processing (Sk11) for dynamically lighting various indicators, and output processing of control signals and the like for outputting data such as lighting signals of various LEDs to the output port (Sk12), random number update process (Sk13) for updating various software random numbers (random number for determination value addition, initial value change random number), time counter update process (Sk14) for updating various time counters, and buffer for normal command transmission The command transmission process (Sk15) for transmitting the stored command or operation detection command to the sub CPU 91a and the external output signal update process (Sk16) for updating the external output signal are sequentially executed, and then saved in the stack area at Sk2. Restored register (Sk20), in step Sk1 Allow sealed interrupt (Sk21), it returns to the interrupt before processing.

  If it is timer interrupt 3 or timer interrupt 4 in the step of Sk5, it is further determined by referring to the branch counter value whether it is 3 or not, ie, timer interrupt 4 (Sk17). If it is not interrupt 4, that is, if it is timer interrupt 3, the passing of the origin of the rotating reels 2L, 2C, 2R (pass of the reel reference position) is checked, and the occurrence of a reel rotation error is detected and stopped. Check if the preparation is complete (whether the stop preparation completion code is set). If the stop preparation is complete and the motor is rotating at a constant speed, operate the stop switch corresponding to the rotating reel. After the origin passing process (Sk18) to be validated and the switch input determination process (Sk19) for determining whether or not the detection state of the switches has changed are sequentially executed, the stack area is determined in Sk2. Returning the saved register (SK20), allow interruption prohibited at step Sk1 (SK21), return to the process before the interrupt process.

  If the timer interrupt is 4 in the step of Sk17, the stop stored in the work of the stop reel is stored when the stop operation position is stored in the work of the stop reel in accordance with the detection of the stop switches 8L, 8C, 8R. A stop switch process (Sk22) for calculating the stop position after determining the stop position from the operation position and counting the number of steps until the stop calculated in the stop switch process is reached, and it is time to stop A stop process (Sk23) for starting braking by two-phase excitation and a final stop process (Sk24) for three-phase excitation after a certain time from the start of braking in the stop process are sequentially executed, and then saved in the stack area at Sk2. Restore the register (Sk20), enable the interrupt that was prohibited in the step of Sk1 (Sk21), Back sense.

  FIG. 18 is a flowchart showing the control contents of the random number update process executed by the main CPU 41a in the timer interrupt 2 of the timer interrupt process (main) described above.

  In the random number update processing, the determination value addition random number of the determination value addition random number counter is read (Sk131), 19463 is added to the read determination value addition random number (Sk132), and the lower 16 bits of the addition value are the initial values. It is determined whether or not the initial value of the random number for determination value addition stored in the storage work matches, that is, whether or not the update of the random number for determination value addition has made one round (Sk133). The value of the decision value addition random number counter is updated with the lower 16 bits of the value as a new decision value addition random number (Sk134), and the process proceeds to Step Sk137.

  When the value of the lower 16 bits of the determination value addition random number and the addition value of 19463 matches the initial value of the determination value addition random number in the step of Sk133, the initial value change random number of the initial value change counter is newly set. The initial value storage work is set as an initial value (Sk135), and the initial value change random number of the initial value change counter is set as a new determination value addition random number in the determination value addition random number counter (Sk136). Proceed to step.

  In step Sk137, the initial value changing random number is updated. That is, 1 is added to the value of the initial value changing random number counter, and when the value after the addition overflows, the value of the initial value changing counter is cleared and returned to 0. Then, after the step of Sk137, the random number update process is terminated and the process returns to the flowchart of FIG.

  FIG. 19 shows a power interruption interrupt process (main main CPU 41a that interrupts and executes a start-up process or a game process when a voltage drop signal is input from the power interruption detection circuit 48 in response to the occurrence of interrupt 2. It is a flowchart which shows the control content of ().

  In the power interruption interruption process (main), first, interruption is prohibited (Sm1). That is, other interrupt processing is prohibited from being executed at the start of the power interruption interrupt processing (main). Next, all registers that may be in use are saved in the stack area (Sm2). 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 (Sm3). At this time, if the voltage drop signal is not input, the register saved in the stack area in Sm2 is restored (Sm4), the interrupt prohibited in the step of Sk1 is permitted (Sm5), and the process before the interrupt is performed. Return.

  If a voltage drop signal is input in step Sk3, destruction diagnosis data (5A (H) in this embodiment) is set (Sm6), and all output ports are initialized (Sm7). . 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 (Sm8), and access to the RAM 41c is performed. It is prohibited (Sm9).

  Then, except for the determination of whether or not the voltage drop signal is input (Sm10, where Sm10 is the same process as Sm3), a loop process in which no process is performed is entered. That is, when the voltage decreases as it is, the operation is stopped internally. Therefore, the operation of the main CPU 41a is surely stopped when power is interrupted. Further, in this loop process, when the voltage recovers and the voltage drop signal is not input, the above-described startup process (main) is executed, if the RAM parity is 0 and the destructive diagnosis data is normal, It will return to the original process.

  In this embodiment, after prohibiting access to the RAM 41c, 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 start process (main) is performed. However, no processing is performed in the loop processing, and the voltage is recovered while the loop processing is being performed, and the activation is performed based on the input of the reset signal from the reset circuit 49. You may make it transfer to a process (main).

  As described above, in the slot machine 1 of this embodiment, every time the random number for determination value addition used for the internal lottery makes one round, the initial value as the starting point of the next cycle is determined based on the random number for initial value change. The update of the determination value addition random number is started from the determined initial value, and the start point of the next cycle changes every time the determination value addition random number makes one round. It becomes difficult to specify the timing when the random number for addition becomes a specific value.

  In particular, in this embodiment, a random number used for an internal lottery in which it is determined whether or not a special role winning that triggers a transition to a gaming state such as BB or RB, which is advantageous to the player, is allowed. Since the determination value addition random number is used, it is possible to prevent the game from being played aiming at the timing at which an internal lottery random number that coincides with the determination value of the special role that greatly affects the player's profit is generated. .

  In this embodiment, every time the determination value addition random number makes one round, the initial value of the determination value addition random number is changed using the initial value change random number. The initial value changing random number may be used to change the initial value, the judgment value adding random number may be updated a predetermined number of times, and the initial value changing random number may be used to change the initial value. The initial value may be changed using a random number for changing the initial value every predetermined time.

  Further, the initial value changing random number when the judgment value adding random number makes one round is used as the initial value of the judgment value adding random number as it is, but the initial value changing random number when the judgment value adding random number makes one round. An operation value obtained by performing a predetermined operation on the initial value changing random number, such as a value obtained by adding or subtracting a specific value to, may be used as the initial value of the determination value adding random number.

  In addition, the decision value addition random number is a new decision value addition random number after adding a certain value that is relatively prime to the total number of decision value addition random numbers and then dividing the remainder by the total number of decision value addition random numbers. It is preferable that the updated random number is not continuous with the pre-update random number and can have periodicity, but it is 1 like the initial value changing random number. You may make it have periodicity by updating by adding or subtracting one by one.

  The initial value changing random number range for determining the initial value of the determination value adding random number is 0 to 65535, which is the same as the determination value adding random number range, and the initial value of the determining value adding random number, that is, the starting point of the next cycle Can be changed over the entire numerical value range of the determination value addition random number, which is preferable because it is difficult to specify the initial value of the determination value addition random number. A random number in a range different from the numerical range may be applied.

  In addition, the determination value addition random number is updated periodically (approximately every 2.24 ms), whereas the initial value change random number is updated periodically after the game in addition to the periodic update. It is also updated in the waiting period and in the waiting period for the reel stop operation after the start of the game. That is, since the update frequency of the determination value addition random number and the initial value change random number are different, it is possible to prevent the initial value of the determination value addition random number from being biased to a specific range.

  In addition, the initial value changing random number is related to the period of waiting for the game start operation after the game ends and the period of waiting for the reel stop operation after the game start, that is, the player's operation as described above. Otherwise, it is updated for each loop of the basic process in an indefinite period that does not proceed, and the update frequency of the initial value changing random number changes due to an uncertain factor of player operation. Thus, the randomness of the initial value changing random number is increased, and the initial value of the determination value adding random number can be further varied.

  In this embodiment, the random number for changing the initial value is updated both in the period waiting for the game start operation after the game ends and in the period waiting for the reel stop operation after the game starts. The randomness of the initial value changing random number can be improved even when the initial value changing random number is updated only in one of the periods.

  In the present embodiment, the setting key switch 37 is ON when the power is turned on, and the stored data in the RAM 41c is normal even when the control state before power interruption is initialized in accordance with the transition to the setting change state. If present, the judgment value addition random number and initial value changing random number before power interruption are maintained, and are obtained by calculation using both the judgment value adding random number and initial value changing random number before power interruption. This value is set as the initial value of the decision value addition random number, and the update of the decision value addition random number starts from the set initial value. Since the starting point varies, it becomes more difficult to specify the timing at which the random number for internal lottery becomes a specific value from the random number for determination value addition.

  In addition, after the power is turned on, when the control state before power interruption is initialized along with the transition to the setting change state, calculation using both the judgment value addition random number and the initial value change random number before power interruption After the decision value addition random number has been updated once from the value obtained in step 1, the initial value of the decision value addition random number that becomes the starting point of the next cycle is determined, and then the decision value addition random number makes one round. Since the initial value of the decision value addition random number is changed every time, the cycle of the first decision value addition random number after power-on and the subsequent cycle are not different, and the transition to the setting change state is made. Accordingly, when the control state before power interruption is initialized, it is possible to perform an internal lottery using a random number for determination value addition with a uniform period, and to ensure the fairness of the game.

  In this embodiment, every time the decision value addition random number makes one round, the initial value of the decision value addition random number is changed using the initial value change random number. A configuration in which the initial value of the decision value addition random number is changed every time using the initial value change random number, and the initial value of the decision value addition random number using the initial value change random number every time the decision value addition random number is updated a predetermined number of times Each time the decision value addition random number is updated for a predetermined period other than one round, such as a configuration for changing the value, a configuration for changing the initial value of the random number for decision value addition using the random number for changing the initial value every predetermined time The initial value of the determination value addition random number may be changed. In such a configuration, after the power is turned on, the determination value addition random number is updated for a predetermined period after the update of the determination value addition random number is started. After that, the initial value of the random number for adding the judgment value using the initial value changing random number for each predetermined period is used. By so changing the value, it is possible to perform internal lottery using the determination value adding random number of equal cycle.

  In this embodiment, all stored data in the RAM 41c is held when the power is cut off. However, when a configuration is adopted in which only the data necessary for restoration is held among the stored data in the RAM 41c when the power is cut off. As described above, after the determination value addition random number has been updated once from the value obtained by the calculation using both the determination value addition random number and the initial value changing random number before power interruption, the next cycle The initial value of the determination value addition random number that is the starting point of the determination value is determined, and then the initial value of the determination value addition random number is changed every time the determination value addition random number makes one round. Since it is not necessary to hold the initial value of the random number for determination value addition, the capacity of backup data held at the time of power interruption can be reduced.

  In addition, in this embodiment, after the power is turned on, when the control state before power interruption is initialized along with the transition to the setting change state, the determination value addition random number and the initial value change random number before power interruption are The value obtained by the calculation using both, that is, the value calculated using a plurality of data held before power interruption is set as the initial value of the random number for determination value addition. It is preferable because it becomes more difficult to specify the timing when the random number for internal lottery becomes a specific value from the random number for addition, but either one of the random number for judgment value addition or the initial value change random number before power interruption You may make it set the value obtained by the used calculation as an initial value of the random number for determination value addition.

  In addition, in this embodiment, after the power is turned on, when the control state before power interruption is initialized along with the transition to the setting change state, the determination value addition random number and the initial value change random number before power interruption are The value obtained by the calculation using both is set as a random number for changing the initial value, and the update of the random number for changing the initial value is started from the set value. Since the starting point for starting the update of the random number also varies, it is difficult to specify the initial value of the random number for determination value addition.

  In addition, after the power is turned on, when the control state before power interruption is initialized with the transition to the setting change state, calculation using both the judgment value addition random number and the initial value change random number before power interruption The value obtained by the above, that is, the value calculated using multiple data held before power interruption is set as the initial value change random number, and the initial value of the random number for judgment value addition is specified. It is preferable because it is difficult to do, but the value obtained by the calculation using either the judgment value addition random number or the initial value changing random number before power interruption is set as the initial value changing random number. You may do it.

  Further, in this embodiment, the initial value of the determination value addition random number obtained by the calculation using both the determination value addition random number and the initial value change random number before power interruption is used as the initial value change random number. Thus, since a program for calculating the initial value changing random number is not required, the program capacity can be reduced.

  In this embodiment, the initial value of the determination value adding random number obtained by the calculation using both the determination value adding random number and the initial value changing random number before power interruption is used as the initial value changing random number. However, even when the initial value change random number is calculated with the same calculation program as the calculation for calculating the initial value of the determination value addition random number, the calculation program for calculating both of these can be shared. , Program capacity can be reduced.

  Further, in this embodiment, when returning to the control state before the power interruption when the power is turned on, the update of the determination value addition random number and the initial value changing random number is started from the value maintained before the power interruption, The judgment value addition random number is judged to have made one round by reaching the initial value maintained before the power interruption, and the initial value of the next cycle is determined based on the initial value changing random number. When returning to the control state before the power interruption when the power is turned on, the update of the random number for judgment value addition and the initial value changing random number will be resumed from the control state before the power interruption. Since the determination value addition random number and the initial value changing random number are also in the state before the power interruption when returning to, the continuity of the control state before the power interruption and after the return can be ensured.

  In addition, when the control state before power interruption is initialized at power-on, and when the control state before power interruption is restored, the value to start updating the random number for judgment value addition and the initial value change random number Therefore, it is more difficult to specify the timing at which the internal lottery random number becomes a specific value from the determination value addition random number and to specify the initial value of the determination value addition random number. .

  In this embodiment, after the power is turned on, when the control state before power interruption is initialized with the transition to the setting change state, the random number for determination value addition maintained from before power interruption is used. When setting the value obtained by the calculation as the initial value of the random number for determination value addition, starting the update of the random number for determination value addition from the set value, and returning to the control state before power interruption when turning on the power, It is configured to start updating the random number for judgment value addition from the value maintained before the power interruption, but the power interruption occurs when the control state before the power interruption is initialized with the transition to the setting change state. Start updating the random number for judgment value addition from the value that has been maintained before, and use the value obtained by calculation using the random number for judgment value addition that has been maintained before power interruption when the power is turned on. And start updating the random number for adding the judgment value from the set value. It may be configured. In addition, after the power is turned on, both the control state before power interruption is initialized with the transition to the setting change state, and the power is turned on both in the case of returning to the control state before power interruption when the power is turned on. Set the value obtained by calculation using the random number for judgment value addition maintained before power interruption at the time of power-on as the initial value of the random number for judgment value addition, and start updating the random number for judgment value addition from the set value It is good also as composition to do.

  In this embodiment, the value obtained by the calculation using the hard random number generated by the random number circuit 42 and the determination value addition random number that is a software random number generated by software is used for internal lottery. Since the random number is used, it becomes more difficult to specify the timing when the random number for internal lottery becomes a specific value.

  Even if the counter circuit 42a of the random number circuit 42 receives an illegal act that does not change the count value, the random number for internal lottery is the same as that of the counter circuit 42a. Since it changes in the range of 65535, the random number for internal lottery is determined by the random number for determination value addition that changes at least in the numerical range of the count value output from the counter circuit 42a (the same as the numerical range of the random number for internal lottery). Random numbers can be generated randomly, and even in such a case, it is difficult to specify the timing at which the internal lottery random number becomes a specific value. That is, even if the count value output from the counter circuit 42a is fixed (the count value does not change), the result of the operation performed on the random number for determination value addition that changes within the same numerical range as the counter circuit 42a is , A random value within the range of 0 to 65535, and measures against such illegal acts can be taken.

  In this embodiment, the counter circuit 42a is a 16-bit counter, but the bit width of the counter circuit 42a may be other than 16 bits. In this case, even when the bit width of the counter circuit 42a is set to a value other than 16, the bit width of the determination value addition random number is made the same as the bit width of the counter circuit 42a, or the bit width of the counter circuit 42a is n. Does not make the predetermined numerical range 2 to the nth power range (for example, when n is 16, the predetermined numerical range is not set to the second power of 16 (0 to 65535), but is set to 0 to 59999). The numerical value range by the software counter is also the same (for example, when a value exceeding the predetermined numerical value range becomes a count value of the counter circuit 42a and a numerical value by the software counter (for example, 60000 or more), a predetermined calculation ( For example, 60000 is subtracted) to obtain a numerical value within a predetermined numerical range.

  In addition, after adding a certain value that is relatively prime to the total number of decision value addition random numbers, the remainder obtained by dividing the remainder by the total number of decision value addition random numbers is a new decision value addition random number. The random number after the update is not continuous with the random number before the update, and sufficient randomness can be ensured with only the random number for the judgment value addition, as described above. Even when an illegal act that does not change the count value output by the counter circuit 42a of 42 is received, it becomes more difficult to specify the timing when the random number for internal lottery becomes a specific value.

  In this embodiment, the value obtained by the calculation using the hard random number generated by the random number circuit 42 and the determination value adding random number that is a software random number generated by software is used for internal lottery. Although it is used as a random number, the random number for determination value addition of the present embodiment itself may be used as a random number for internal lottery without using a hard random number, or the random number for addition of the determination value of this embodiment and the initial value change A value obtained as a result of calculation using random numbers may be used as a random number for internal lottery.

  As described above, the first embodiment of the present invention has been described with reference to the drawings. However, the present invention is not limited to this embodiment, and modifications and additions within the scope of the present invention are included in the present invention. Needless to say.

  For example, in the first embodiment, a slot machine for setting bets using medals and credits is used. However, the present invention is not limited to this, and slots for setting bets using game balls. It may be a machine or a fully credit type slot machine that uses only credits to set bets.

  Further, in addition to the medal insertion mechanism such as the flow path switching solenoid 30 and the insertion medal sensor 31, a ball take-in device that takes in a game ball, and a take-in ball that detects a game ball taken in by the ball take-in device In addition to a medal payout mechanism, such as a hopper motor 34b and a payout sensor 34c, a ball payout device for paying out game balls and a payout ball detection switch for detecting game balls payed out by the ball payout device It is possible to set a bet number using both medals and game balls and play a game, and the present invention may be applied to a slot machine in which medals and game balls are paid out by winning.

  Embodiment 2 of the present invention will be described below with reference to the drawings. First, an overall configuration of a pachinko gaming machine 201 that is an example of a gaming machine will be described. FIG. 20 is a front view of the pachinko gaming machine 201 as seen from the front.

  The pachinko gaming machine 201 includes an outer frame (not shown) formed in a vertically long rectangular shape, and a game frame attached to the inside of the outer frame so as to be opened and closed. Further, the pachinko gaming machine 201 has a glass door frame 202 formed in a frame shape provided in the game frame so as to be opened and closed. The game frame includes a front frame (not shown) that can be opened and closed with respect to the outer frame, a mechanism plate (not shown) to which mechanism parts and the like are attached, and various parts (games to be described later) attached to them. And the board 206).

  On the lower surface of the glass door frame 202 is a hitting ball supply tray (upper plate) 203. Under the hitting ball supply tray 203, an extra ball receiving tray 204 for storing game balls that cannot be accommodated in the hitting ball supply tray 203, and a hitting operation handle (operation knob) 205 for firing the hitting ball are provided. A game board 206 is detachably attached to the back surface of the glass door frame 202. The game board 206 is a structure including a plate-like body constituting the game board 206 and various components attached to the plate-like body. In addition, a game area 207 is formed on the front surface of the game board 206 in which a game ball that has been struck can flow down.

  In the vicinity of the center of the game area 207, an effect display device 209 composed of a liquid crystal display device (LCD) is provided. The effect display device 209 performs variable display (variation) of the effect symbol (decoration symbol) in synchronization with the variable display of the first special symbol or the second special symbol. Therefore, the effect display device 209 corresponds to a variable display device that performs variable display of effect symbols (decorative symbols) as identification information. The effect display device 209 is controlled by an effect control microcomputer mounted on the effect control board 90. When the first special symbol display 208a is executing variable display of the first special symbol in the effect control microcomputer, the symbol display areas 209L, 209C, and 209R in the effect display device 209 are accompanied by the variable display. When the effect display is executed and the variable display of the second special symbol is executed by the second special symbol display device 208b, the effect display is executed by the effect display device 209 along with the variable display, so the progress of the game The situation can be easily understood. In the symbol display area 209L, variable display of the left symbol of the decorative symbol is executed. In the symbol display area 209C, variable display of the middle symbol of the decorative symbol is executed. In the symbol display area 209R, variable display of the right symbol of the decorative symbol is performed. Executed. The arrangement positions of the symbol display areas 209L, 209C, and 209R on the display screen of the effect display device 209 may be fixed or may be changed according to the progress of the game.

  On the left side of the upper portion of the effect display device 209 in the game board 206, a first special symbol display (first variable display means) 208a for variably displaying the first special symbol as identification information is provided. In this embodiment, the first special symbol display 208a is realized by a simple and small display (for example, 7 segment LED) capable of variably displaying numbers 0 to 9. That is, the first special symbol display 208a is configured to variably display numbers (or symbols) from 0 to 9. A second special symbol display (second variable display means) 208b for variably displaying the second special symbol as identification information is provided on the right side of the top of the effect display device 209 in the game board 206. The second special symbol display 208b is realized by a simple and small display (for example, 7 segment LED) capable of variably displaying numbers 0 to 9. That is, the second special symbol display 208b is configured to variably display numbers (or symbols) from 0 to 9.

  In the present embodiment, the type of the first special symbol and the type of the second special symbol are the same (for example, both are numbers from 0 to 9), but the types may be different. The first special symbol display 208a and the second special symbol display 208b may be configured to variably display, for example, a number (or a two-digit symbol) of 00 to 99, for example.

  Hereinafter, the first special symbol and the second special symbol may be collectively referred to as a special symbol, and the first special symbol indicator 208a and the second special symbol indicator 208b may be collectively referred to as a special symbol indicator.

  For the variable display of the first special symbol or the second special symbol, the first start condition or the second start condition, which is the variable display execution condition, is satisfied (for example, the game ball has the first start winning port 213 or the second start winning port) 214 (after having won 214), a variable display start condition (for example, when the number of reserved memories is not 0 and the variable display of the first special symbol and the second special symbol is not executed) When the variable display time (fluctuation time) elapses, a display result (stop symbol) is derived and displayed. Note that winning means that a game ball has entered a predetermined area such as a winning opening. Deriving and displaying the display result means that the symbol (example of identification information) is finally stopped and displayed. In the present embodiment, the variable display start condition is established in the order in which the start winnings are generated regardless of the winning at the first starting winning port 213 and the winning at the second starting winning port 214. However, among the winnings at the first starting winning port 213 and the winnings at the second starting winning port 214, for example, the winning at the second starting winning port 214 is given priority and the variable display start condition is satisfied. good. In this case, if the variable display of the first special symbol and the second special symbol is not executed and the jackpot game is not executed, even if the first reserved memory number is not zero, 2 The variable display of the second special symbol is continuously executed until the number of reserved memories becomes zero.

  The effect display device 209 is for decoration (effect) during the variable display time of the first special symbol on the first special symbol display 208a and during the variable display time of the second special symbol on the second special symbol display 208b. The display design (decorative design) is variably displayed. The variable display of the first special symbol on the first special symbol display 208a and the variable display of the effect symbol on the effect display device 209 are synchronized. The variable display of the second special symbol on the second special symbol display 208b and the variable display of the effect symbol on the effect display device 209 are synchronized. Synchronous means that the start time and end time of variable display are substantially the same (may be exactly the same), and the period of variable display is substantially the same (may be exactly the same). Further, when the jackpot symbol is stopped and displayed on the first special symbol display 208a and when the jackpot symbol is stopped and displayed on the second special symbol display 208b, the effect display device 209 causes the jackpot to be recalled. The combination of is stopped and displayed.

  A winning device having a first start winning port 213 is provided below the effect display device 209. The game ball that has won the first start winning opening 213 is guided to the back of the game board 206 and detected by the first start opening switch 213a.

  A variable winning ball device 215 having a second starting winning port 214 through which a game ball can be won is provided below the winning device having the first starting winning port (first starting port) 213. The game ball that has won the second start winning opening (second start opening) 214 is guided to the back of the game board 206 and detected by the second start opening switch 214a. The variable winning ball device 215 is opened by a solenoid 216. When the variable winning ball apparatus 215 is in the open state, the game ball can be won in the second start winning opening 214 (it is easy to start winning), which is advantageous for the player. In a state where the variable winning ball device 215 is in the open state, it is easier for the game ball to win the second starting winning port 214 than the first starting winning port 213. In addition, in a state where the variable winning ball device 215 is in the closed state, the game ball does not win the second start winning port 214. In the state where the variable winning ball device 215 is in the closed state, it may be configured so that it is difficult to win, but it is possible to win (that is, the game ball is difficult to win).

  Hereinafter, the first start winning port 213 and the second start winning port 214 may be collectively referred to as a start winning port or a starting port.

  When the variable winning ball device 215 is controlled to be in the open state, the game ball heading toward the variable winning ball device 215 is very likely to win the second start winning port 214. The first start winning opening 213 is provided immediately below the effect display device 209, but the interval between the lower end of the effect display device 209 and the first start winning opening 213 is further reduced, or the first start winning opening is set. It is difficult to guide the game balls to the first start winning port 213 by arranging the nails densely around the first start winning port 213, and the winning rate of the second start winning port 214. It is also possible to make the direction higher than the winning rate of the first start winning opening 213.

  Below the first special symbol display 208a, the number of effective winning balls that have entered the first start winning opening 213, that is, the first reserved memory number (the reserved memory is also referred to as the start memory or the start prize memory) is displayed 4. A first special symbol storage memory display 218a composed of two indicators (for example, LEDs) is provided. The first special symbol storage memory display 218a increases the number of indicators that are turned on by one every time there is an effective start winning. Then, every time variable display on the first special symbol display 208a is started, the number of indicators to be turned on is reduced by one.

  Below the second special symbol display 208b, a second special symbol hold comprising four indicators (for example, LEDs) for displaying the number of effective winning balls that have entered the second start winning opening 214, that is, the second reserved memory number. A storage indicator 218b is provided. The second special symbol storage memory display 218b increases the number of indicators to be turned on by 1 every time there is an effective start winning. Then, every time the variable display on the second special symbol display 208b is started, the number of indicators to be turned on is reduced by one.

  In addition, the display screen of the effect display device 209 displays an area (hereinafter referred to as a summed pending storage display unit 218c) that displays the total number (the summed pending memory number) that is the sum of the first reserved memory number and the second reserved memory number. .) Is provided. Since the summation pending storage display unit 218c for displaying the total number is provided, it is possible to easily grasp the total number of execution conditions that have not met the variable display start condition. In addition, since the total reserved memory display unit 218c is provided, the first special symbol reserved memory display 218a and the second special symbol reserved memory display 218b may not be provided.

  In this embodiment, as shown in FIG. 20, a variable winning ball device 215 that opens and closes only with respect to the second starting winning port 214 is provided. A configuration in which a variable winning ball apparatus that performs an opening / closing operation is provided for any of the winning openings 214 may be adopted.

  As shown in FIG. 20, a special variable winning ball device 220 is provided below the variable winning ball device 215. The special variable winning ball apparatus 220 includes an opening / closing plate, and when a specific display result (big hit symbol) is derived and displayed on the first special symbol display 208a, and on the second special symbol display 208b, a specific display result (big hit symbol). When the open / close plate is controlled to be opened by the solenoid 221 in a specific game state (a big hit game state) that occurs when the symbol is derived and displayed, the large winning opening serving as a winning area is opened. The game ball that has won the big winning opening is detected by the count switch 223.

  A normal symbol display 210 is provided at the lower right side of the game board 206. The normal symbol display 210 variably displays a plurality of types of identification information called “normal symbols” (for example, “◯” and “X”).

  When the game ball passes through the gate 232 and is detected by the gate switch 232a, the variable display of the normal symbol display 210 is started. In the present embodiment, variable display is performed by alternately lighting the upper and lower lamps (the symbols can be visually recognized when turned on). For example, if the lower lamp is turned on at the end of the variable display, it is a hit. And when the stop symbol in the normal symbol display 210 is a predetermined symbol (winning symbol), the variable winning ball apparatus 215 is opened for a predetermined number of times. That is, the state of the variable winning ball device 215 is a state that is advantageous from a disadvantageous state for the player when the stop symbol of the normal symbol is a winning symbol (a state in which a game ball can be won at the second start winning port 214). To change. In the vicinity of the normal symbol display 210, a normal symbol hold storage display 241 having four indicators (for example, LEDs) for displaying the number of winning balls that have passed through the gate 232 is provided. Each time there is a game ball passing through the gate 232, that is, every time a game ball is detected by the gate switch 232a, the normal symbol storage memory display 241 increases the number of indicators that are turned on by one. Then, each time the variable display of the normal symbol display 210 is started, the number of indicators that are lit is reduced by one. Further, in the probability variation state in which the probability of being determined to be a big hit as compared to the normal state is high, the probability that the stop symbol in the normal symbol display 210 becomes a winning symbol is increased, and the variable winning ball apparatus 215 The opening time becomes longer and the number of opening times is increased. Further, in the short-time state (a gaming state in which the special symbol variable display time is shortened), the opening time of the variable winning ball device 215 may be lengthened and the number of times of opening may be increased.

  Decorative LEDs 225 that are blinked and displayed during the game are provided around the left and right sides of the game area 207 of the game board 206, and an out port 226 into which a hit ball that has not been won is taken in at the bottom. In addition, two speakers 227R and 227L that utter sound effects and sounds as predetermined sound outputs are provided on the left and right upper portions outside the game area 207. A top frame LED 228a, a left frame LED 228b, and a right frame LED 228c provided on the front frame are provided on the outer periphery upper portion, the outer periphery left portion, and the outer periphery right portion of the game area 207. In addition, a prize ball LED 251 that is turned on when there is a remaining number of prize balls is provided in the vicinity of the left frame LED 228b, and a ball cut LED 252 that is turned on when the supply ball is cut is provided in the vicinity of the right frame LED 228c. . The top frame LED 228 a, the left frame LED 228 b, the right frame LED 228 c, and the decoration LED 225 are examples of effects light emitters provided in the pachinko gaming machine 201. In addition to the above-mentioned various LEDs for effects (decorations), LEDs and lamps for effects are installed.

  The pachinko gaming machine 201 has a ball hitting device that drives a driving motor in response to the player operating the hitting operation handle 205 and uses the rotational force of the driving motor to launch a game ball into the game area 207 (see FIG. Not shown). A game ball launched from the ball striking device enters the game area 207 through a ball striking rail formed in a circular shape so as to surround the game area 207, and then descends the game area 207. When the game ball enters the first start winning opening 213 and is detected by the first start opening switch 213a, if the variable display of the first special symbol can be started (for example, the variable display of the special symbol ends, 1), the first special symbol display 208a starts variable display (variation) of the first special symbol, and the effect display device 209 starts variable display of the effect symbol (decoration symbol). Is done. That is, the variable display of the first special symbol and the effect symbol corresponds to winning in the first start winning opening 213. If the variable display of the first special symbol cannot be started, the first reserved memory number is increased by 1 on the condition that the first reserved memory number has not reached the upper limit value.

  When the game ball enters the second start winning port 214 and is detected by the second start port switch 214a, if the variable display of the second special symbol can be started (for example, the special symbol variable display ends, 2), the second special symbol display 208b starts variable display (variation) of the second special symbol, and the effect display device 209 starts variable display of the effect symbol (decoration symbol). Is done. That is, the variable display of the second special symbol and the effect symbol corresponds to winning in the second start winning opening 214. If the variable display of the second special symbol cannot be started, the second reserved memory number is increased by 1 on condition that the second reserved memory number has not reached the upper limit value.

  Further, an operation button 358 that can be pressed by the player and outputs a pressing signal when the button is pressed is provided at the lower left portion of the gaming machine. When a predetermined announcement effect is being performed, an effect display in which the effect image in the display area of the effect display device 209 changes is performed in response to the operation button 358 being operated by the player.

  FIG. 21 is a block diagram showing an example of a circuit configuration of the main board (game control board) 231. As shown in FIG. FIG. 21 also shows a payout control board 237, an effect control board 280, and the like. A game control microcomputer (corresponding to a game control means) 260 for controlling the pachinko gaming machine 201 according to a program is mounted on the main board 231. The game control microcomputer 760 includes a ROM 254 for storing a game control (game progress control) program and the like, a RAM 255 as storage means used as a work memory, a CPU 256 for performing control operations according to the program, and an I / O port unit 257. including. In this embodiment, the ROM 254 and the RAM 255 are built in the game control microcomputer 760. That is, the game control microcomputer 760 is a one-chip microcomputer. The one-chip microcomputer may include at least the RAM 256 and the RAM 255, and the ROM 254 may be external or internal. Further, the I / O port unit 257 may be externally attached. The game control microcomputer 760 further includes a random number circuit 706 that generates hardware random numbers (random numbers generated by the hardware circuit).

  The random number circuit 706 counts an internal clock signal for driving each block in the game control microcomputer 760. Note that a microcomputer configured so that a clock signal obtained by dividing the internal clock signal or a clock signal whose frequency is increased is supplied to the random number circuit 706 may be used.

  A counter circuit 711 used for generating random numbers is mounted on the main board 231. The game control microcomputer 760 receives data output from the counter circuit 711 at a predetermined time, and adds the input data to a count value of a counter (RAM 255 area) for generating a random number.

  In the game control microcomputer 760, the CPU 256 executes control in accordance with the program stored in the ROM 254. Therefore, the game control microcomputer 760 (or the CPU 256) executes (or performs processing) hereinafter. Specifically, the CPU 256 executes control according to a program. The same applies to a microcomputer mounted on a board other than the main board 231.

  The RAM 255 is a backup RAM as a non-volatile storage means, part or all of which is backed up by a backup power source created on the power supply board. That is, even if the power supply to the gaming machine is stopped, a part or all of the contents of the RAM 255 is stored for a predetermined period (until the backup power supply cannot be supplied because the capacitor as the backup power supply is discharged). In particular, at least data corresponding to the game state, that is, the control state of the game control means (the value of the special symbol process flag or the total pending storage number counter) and the data indicating the number of unpaid winning balls are stored in the backup RAM. The data corresponding to the control state of the game control means is data necessary for restoring the control state before the occurrence of a power failure or the like based on the data when the power is restored after a power failure or the like occurs. Further, data corresponding to the control state and data indicating the number of unpaid winning balls are defined as data indicating the progress state of the game. In the present embodiment, the entire RAM 255 is backed up.

  A reset signal (not shown) from the power supply board is input to the reset terminal of the game control microcomputer 760. A reset circuit for generating a reset signal supplied to the game control microcomputer 760 and the like is mounted on the power supply board. When the reset signal becomes high level, the game control microcomputer 760 and the like become operable, and when the reset signal becomes low level, the game control microcomputer 760 and the like become inoperative. Therefore, an allowable signal that allows the operation of the game control microcomputer 760 or the like is output during a period when the reset signal is at a high level, and a game control microcomputer is output when the reset signal is at a low level. An operation stop signal for stopping the operation of 760 or the like is output. The reset circuit may be mounted on each electric component control board (a board on which a microcomputer for controlling the electric parts is mounted).

  Furthermore, a power-off signal indicating that the power supply voltage from the power supply board has dropped below a predetermined value is input to the input port of the game control microcomputer 760. That is, the power supply board monitors the voltage value of a predetermined voltage (for example, DC30V or DC5V) used in the gaming machine, and when the voltage value decreases to a predetermined value (the power supply voltage is reduced). A power supply monitoring circuit that outputs a power-off signal indicating that). Further, a clear signal (not shown) indicating that the clear switch for instructing to clear the contents of the RAM is operated is input to the input port of the game control microcomputer 760.

  An input driver circuit 258 for supplying detection signals from the gate switch 232a, the first start port switch 213a, the second start port switch 214a and the count switch 223 to the game control microcomputer 760 is also mounted on the main board 231. Also, an output circuit 59 for driving a solenoid 216 for opening and closing the variable winning ball device 215 and a solenoid 221 for opening and closing the special variable winning ball device 220 that forms a big winning opening according to a command from the game control microcomputer 760 is also provided. 231. Further, an information output circuit (not shown) for outputting an information output signal such as jackpot information indicating the occurrence of a jackpot gaming state to an external device such as a hall computer is also mounted on the main board 231.

  In the present embodiment, the effect control means (configured by an effect control microcomputer) mounted on the effect control board 280 directs the contents of the effect from the game control microcomputer 760 via the relay board 377. The control command is received, and display control is performed with the effect display device 209 that variably displays the effect symbol.

  FIG. 22 is a block diagram showing the relationship between the counter circuit 711 and the game control microcomputer 760. As shown in FIG. 22, the counter circuit 711 receives a clock signal output from a pulse oscillator 713 (not shown in FIG. 21) mounted on the main board 231, and counts at the rising or falling edge of the clock signal. Increase the value by one. The counter circuit 711 is a 16-bit counter, for example. Therefore, the output (that is, the count value) of the counter circuit 711 is output through 16 signal lines. The output of the counter circuit 711 is input to the first latch circuit 714 and the second latch circuit 715. The count value of the counter circuit 711 is one of 0 to 65535, and increments by one. That is, the value increases by one.

  In this example, the counter circuit 711 is a 16-bit counter, but the bit width of the counter circuit 711 is not limited to 16. However, even when the bit width of the counter circuit 711 is a value other than 16, it is preferable that the bit width of the software counter is the same as the bit width of the counter circuit 711. When the bit width of the counter circuit 711 is n but the predetermined numerical range is not set to a power of 2 n (for example, when n is 16, the predetermined numerical range is set to 2 16 (0 to 0). It is preferable to set the numerical value range by the software counter to be the same when the value is set to 0 to 59999 instead of 65535). In this case, the CPU 256 subtracts a predetermined calculation (for example, 60000) when a value exceeding the predetermined numerical range becomes a count value of the counter circuit 711 and a numerical value (for example, 60000 or more) by the software counter. ) To obtain a numerical value within a predetermined numerical range.

  The oscillation frequency of the clock signal output from the pulse oscillator 713 is arbitrary, but the count value of the counter circuit 711 is used by the game control microcomputer 760 to generate a random number for determination. The oscillation frequency is different from the operation frequency of the CPU 256, and the oscillation frequency of the clock signal is preferably not an integer multiple of the operation frequency of the CPU 256 (for example, the operation frequency of the CPU 256 is 15.872 MHz and the oscillation of the clock signal is performed). Frequency 20 MHz). As will be described later, the CPU 256 starts the game control process periodically (for example, every 2 ms), and the count value of the software counter (a counter using the RAM 255) whose value is updated by the game control process and the counter circuit Since a random number is generated by performing an operation on the count value of 711, it is preferable for generating a random number that the update cycle of the count value of the software counter and the update cycle of the counter circuit 711 do not have an integer multiple relationship. Because. Furthermore, it is more preferable that the oscillation frequency of the clock signal and the operating frequency of the CPU 256 are frequencies that are not divisible by the other.

  As shown in FIG. 22, the detection signal of the first start port switch 213a is input to the first latch circuit 714 as a latch signal. Further, the detection signal of the second start port switch 214a is input to the second latch circuit 715 as a latch signal. The first latch circuit 714 latches the count value of the counter circuit 711 when the first start port switch 213a detects a game ball, that is, when there is a first start prize. The second latch circuit 715 latches the count value of the counter circuit 711 when the second start port switch 214a detects a game ball, that is, when there is a second start winning. According to the configuration shown in FIG. 22, even when a plurality of types of starting conditions are satisfied at the same time, the count value of the counter circuit 711 is latched by the respective latch circuits in accordance with the satisfaction of the respective starting conditions. The numerical value generated when the starting condition is satisfied is accurate.

  FIG. 23 is a block diagram illustrating a circuit configuration example of the relay board 377, the effect control board 280, the lamp driver board 235, and the audio output board 270. In the example shown in FIG. 23, the lamp driver board 235 and the audio output board 270 are not equipped with a microcomputer, but may be equipped with a microcomputer. Also, only the effect control board 280 may be provided for effect control without providing the lamp driver board 235 and the audio output board 270.

  The effect control board 280 includes an effect control microcomputer 310 including an effect control CPU 311 and a RAM. The RAM may be externally attached. In the effect control board 280, the effect control CPU 311 operates in accordance with a program stored in a built-in or external ROM (not shown), and receives a capture signal from the main board 231 input via the relay board 377 ( In response to the (effect control INT signal), the effect control command is received via the input driver 312 and the input port 313. In addition, the effect control CPU 311 causes the VDP (video display processor) 319 to perform display control of the effect display device 209 based on the effect control command.

  In the present embodiment, a VDP 319 that performs display control of the effect display device 209 in cooperation with the effect control microcomputer 310 is mounted on the effect control board 280. The VDP 319 has an address space independent of the effect control microcomputer 310, and maps the VRAM therein. The VRAM is a buffer memory for expanding image data generated by the VDP. Then, the VDP 319 outputs the image data in the VRAM to the effect display device 209.

  The effect control CPU 311 reads necessary data from a character ROM (not shown) in accordance with the received effect control command. The character ROM is for storing character image data displayed on the effect display device 209, specifically, a person, characters, figures, symbols, etc. (including effect symbols) in advance. The effect control CPU 311 outputs the data read from the character ROM to the VDP 319. The VDP 319 executes display control based on the data input from the effect control CPU 311. Further, the effect control CPU 311 inputs a pressing signal from the operation button 358 via the input port 316.

  The effect control command and the effect control INT signal are first input to the input driver 312 on the effect control board 280. The input driver 312 passes the signal input from the relay board 377 only in the direction toward the inside of the effect control board 280 (does not pass the signal in the direction from the inside of the effect control board 280 to the relay board 377). It is also a unidirectional circuit as a regulating means.

  The relay board 377 allows signal input from the main board 231 to pass only in the direction toward the effect control board 280 (no signal is passed in the direction from the effect control board 280 to the relay board 377) as signal direction regulating means. The unidirectional circuit 377A is mounted. For example, a diode or a transistor is used as the unidirectional circuit. FIG. 23 illustrates a diode. A unidirectional circuit 377A is provided for each signal. Further, since the effect control command and the effect control INT signal are output from the main board 231 via the output port 771 which is also a unidirectional circuit, the signal from the relay board 377 toward the inside of the main board 231 is restricted. That is, the signal from the relay board 377 does not enter the inside of the main board 231 (the game control microcomputer 760 side). The output port 771 is a part of the I / O port unit 257 shown in FIG. Further, a signal driver circuit which is a unidirectional circuit may be further provided outside the output port 771 (on the relay board 377 side).

  Further, the effect control CPU 311 outputs a signal for driving the LED to the lamp driver board 235 via the output port 315. Further, the effect control CPU 311 outputs the sound number data to the audio output board 270 via the output port 314.

  In the lamp driver board 235, a signal for driving the LED is input to the LED driver 552 via the input driver 551. The LED driver 552 supplies a drive signal to each LED provided on the frame side such as the top frame LED 228a, the left frame LED 228b, and the right frame LED 228c. In addition, a drive signal is supplied to the decoration LED 225 provided on the game board side. If a light emitter other than the LED is provided, a drive circuit (driver) for driving the light emitter is mounted on the lamp driver substrate 235.

  In the voice output board 270, the sound number data is input to the voice synthesis IC 903 via the input driver 902. The voice synthesizing IC 903 generates a voice or sound effect corresponding to the sound number data and outputs it to the amplifier circuit 905. The amplifier circuit 905 outputs the audio signal obtained by amplifying the output level of the speech synthesis IC 903 to a level corresponding to the volume set by the volume 906 to the speakers 227R and 227L. The audio data ROM 904 stores control data corresponding to the sound number data. The control data corresponding to the sound number data is a collection of data showing the sound effect or sound output mode in a time series in a predetermined period (for example, the changing period of the effect design).

  Next, the operation of the gaming machine will be described. FIG. 24 is a flowchart showing main processing executed by the game control microcomputer 760 on the main board 231. When power is supplied to the gaming machine and power supply is started, the input level of the reset terminal to which the reset signal is input becomes high level, and the gaming control microcomputer 760 (specifically, the CPU 256) After executing a security check process, which is a process for confirming whether the contents of the program are valid, the main process after S1 is started. In the main process, the CPU 256 first performs necessary initial settings.

  In the initial setting process, the CPU 256 first sets the interrupt prohibition (S1). Next, the interrupt mode is set to interrupt mode 2 (S2), and a stack pointer designation address is set to the stack pointer (S3). Then, after initialization of the built-in device (such as CTC (counter / timer) and PIO (parallel input / output port) which are built-in devices (built-in peripheral circuits)) is performed (S4), the RAM is made accessible. Set (S5). In interrupt mode 2, the address synthesized from the value (1 byte) of the specific register (I register) built in the CPU 256 and the interrupt vector (1 byte: least significant bit 0) output from the built-in device is This mode indicates an interrupt address.

  Next, the CPU 256 checks the state of the output signal of the clear switch (for example, mounted on the power supply board) input via the input port (S6). When the on-state is detected in the confirmation, the CPU 256 executes normal initialization processing (S9 to S15).

  If the clear switch is not on, check whether data protection processing of the backup RAM area (for example, power supply stop processing such as addition of parity data) was performed when power supply to the gaming machine was stopped (S7). If it is confirmed that such protection processing has not been performed, the CPU 256 executes initialization processing associated with the RAM abnormality (S20, S21, S11 to S15). Whether there is backup data in the backup RAM area is confirmed by, for example, the state of the backup flag set in the backup RAM area in the power supply stop process.

  After confirming that the power supply stop process has been performed, the CPU 256 checks the data in the backup RAM area (S8). In this embodiment, a parity check is performed as a data check. Therefore, in S8, the calculated checksum is compared with the checksum calculated and stored by the same process in the power supply stop process. When the power supply is stopped after an unexpected power failure or the like, the data in the backup RAM area should be saved, so the check result (comparison result) is normal (matched). That the check result is not normal means that the data in the backup RAM area is different from the data when the power supply is stopped. In such a case, the internal state cannot be returned to the state at the time of stopping the power supply, so the initialization process associated with the RAM abnormality is executed (S20, S21, S11 to S15).

  If the check result is normal, the CPU 256 performs a game state restoration process (in S22 to S25) for returning the internal state of the game control means and the control state of the electric component control means such as the effect control means to the state when the power supply is stopped. Process). Specifically, the start address of the backup setting table stored in the ROM 254 is set as a pointer (S22), and the contents of the backup setting table are sequentially set in the work area (area in the RAM 255) (S23). The work area is backed up by a backup power source. In the backup setting table, initialization data for an area that may be initialized in the work area is set. By the processing of S22 and S23, the saved contents remain as they are in the portion of the work area that should not be initialized. The part that should not be initialized is, for example, data indicating the game state before the power supply is stopped (special symbol process flag, probability change flag, time reduction flag, various software random numbers, etc.), and the area where the output state of the output port is saved (Output port buffer), a portion where data indicating the number of unpaid prize balls is set.

  Further, the CPU 256 transmits a power failure recovery designation command as an initialization command at the time of power supply recovery (S24). In addition, a display result specifying command, a combined pending storage number designation command, and a variation pattern command are transmitted (S25). Then, the process proceeds to S14. The variation pattern command is transmitted only when the special symbol and the decorative symbol are variably displayed when the power supply is stopped. Whether or not the variable display has been performed is determined by, for example, a special symbol process flag stored in the RAM 255. However, even if a special symbol and a decorative symbol are variably displayed when a power failure occurs, a gaming machine configured not to continue the variable display when power supply is restored does not transmit a variation pattern command. In the gaming machine configured as described above, the effect control microcomputer 310 specifies the display result of the decorative design based on the received display result specifying command, and the game control microcomputer 760 when the variation time has elapsed. When the symbol confirmation designation command transmitted from is received, the display result is derived and displayed on the effect display device 209.

  There are a plurality of types of commands as the display result specifying command. In the process of S24, data indicating the display result specifying command (the display result specifying command transmitted last when the power supply is stopped) stored in the RAM 255. Send a command based on The total pending storage number designation command includes data indicating the total pending storage number, but in the process of S23, the total pending storage number designation command including data indicating the total pending storage number stored in the RAM 255 is transmitted. To do. Then, as a variation pattern command, a command based on data indicating the variation pattern command stored in the RAM 255 (the variation pattern command transmitted last when the power supply is stopped) is transmitted.

  In this embodiment, it is confirmed whether or not the data in the backup RAM area is stored using both the backup flag and the check data, but only one of them may be used. That is, either the backup flag or the check data may be used as an opportunity for executing the game state restoration process.

  In the normal initialization process, the CPU 256 first clears the RAM area other than the non-initialization area that is not cleared in the normal initialization process (S9). The non-initialized area includes software random numbers and the like, and in a normal initialization process, these software random numbers are not cleared and the state before power interruption is maintained.

  Next, a software random number stored in the non-initialized area of the RAM 255, that is, a software random number held before power interruption, a later-described random 1 counter value and a random 6 counter value are added, and the added value Random 1 (Random 6 is the same) divided by the total number of values (65536), the remainder (lower 16 bits) is used as the random 1 counter value, random 6 counter value, and random 1 initial value. Set (S10).

  In S <b> 14, the CPU 256 executes a random number circuit setting process for initially setting the random number circuit 706. For example, the CPU 256 performs setting according to the random number circuit setting program so that the random number circuit 706 updates the random number value.

  In S15, the CPU 256 sets a CTC register built in the game control microcomputer 760 so that a timer interrupt is periodically generated every predetermined time (for example, 2 ms). That is, a value corresponding to, for example, 2 ms is set in a predetermined register (time constant register) as an initial value. In this embodiment, it is assumed that a timer interrupt is periodically taken every 2 ms.

  Next, the start address of the initialization setting table stored in the ROM 254 is set as a pointer (S11), and the contents of the initialization setting table are sequentially set in the work area (S12).

  By the processing of S11 and S12, for example, initial values are set to flags for selectively performing processing according to the control state, such as a special symbol buffer, a total prize ball number storage buffer, and a special symbol process flag.

  Next, the CPU 256 initializes a sub board (a board on which a microcomputer other than the main board 231 is mounted) (a command indicating that the game control microcomputer 760 has executed initialization processing). (S13) is transmitted to the sub-board (S13). For example, when the effect control microcomputer 310 receives the initialization designation command, the effect display device 209 performs screen display for notifying that the control of the gaming machine has been performed, that is, initialization notification.

  In the initialization process associated with the RAM abnormality, the CPU 256 first clears all the RAM areas including the non-initialized area (S20). That is, in the initialization process associated with the RAM abnormality, all data including software random numbers are initialized.

  Next, the chip ID of the game control microcomputer 760 (a 4-byte value individually given at the time of manufacture of the game control microcomputer 760 as in the first embodiment) is read, and the lower 2 bytes of the read chip ID are read. Values are set as a random 1 counter value, a random 6 counter value, and a random 1 initial value, which will be described later (S21).

  Note that the processing of S11 to S15 is the same as the normal initialization processing, and thus description thereof is omitted here.

  When the execution of the initialization process (S10 to S15 or S20, S21, S11 to S15) is completed, the CPU 256 repeatedly executes the display random number update process (S17) and the initial value random number update process (S18) in the main process. To do. When executing the display random number update process and the initial value random number update process, the interrupt disabled state is set (S16), and when the display random number update process and the initial value random number update process are completed, the interrupt enabled state is set. (S19). In this embodiment, the display random number is a random number for determining a variation pattern and a random number for determining whether or not to reach, and the display random number update process is a counter for generating a display random number. This is a process for updating the count value. The initial value random number update process is a process for updating the count value of the counter for generating the initial value random numbers (random numbers 6 and 7 to be described later). The initial value random number is a random number for determining an initial value of a count value of a counter for generating random 1 and random 5 described later.

  When the timer interrupt occurs, the CPU 256 executes the timer interrupt process of S30 to S44 shown in FIG. In the timer interrupt process, first, a power-off detection process for detecting whether or not a power-off signal is output (whether or not an on-state is turned on) is executed (S30). The power-off signal is output, for example, when a voltage drop monitoring circuit mounted on the power supply board detects a drop in the power supply voltage supplied to the gaming machine. In the power-off detection process, when detecting that the power-off signal has been output, the CPU 256 executes a power supply stop process for saving necessary data in the backup RAM area. Next, detection signals of the gate switch 232a, the first start port switch 213a, the second start port switch 214a, and the count switch 223 are input via the input driver circuit 258, and the state determination is performed (switch processing: S31). .

  Next, the CPU 256, the first special symbol display 208a, the second special symbol display 208b, the normal symbol display 210, the first special symbol hold storage display 218a, the second special symbol hold storage display 218b, the normal symbol A display control process for controlling the display of the on-hold storage display 241 is executed (S32). For the first special symbol display 208a, the second special symbol display 208b, and the normal symbol display 210, a control for outputting a drive signal to each display according to the contents of the output buffer set in S42 and S43. Execute.

  Next, a process of updating the count value of each counter for generating each determination random number such as a random number for determining a big hit symbol used for game control is performed (determination random number update process: S33). The CPU 256 further performs processing for updating the count value of the counter for generating the initial value random number and the display random number (initial value random number update processing, display random number update processing: S34, S35).

  FIG. 26 is an explanatory diagram showing each random number. Each random number is used as follows. Random 1 is a software random number. For random 1, those values and the value of a random number (hard random number) generated by a hardware circuit (counter circuit 711 shown in FIG. 22) external to the game control microcomputer 760 are used. The final result is a random value. The final random value is a value that is compared with the determination value. The random numbers 2-2, 3, and 4 are values created by adding the random number value of the random number circuit 706 built in the game control microcomputer 760 to the software random number. Random numbers 5, 6, and 7 are software random numbers generated by the game control microcomputer 760 based on a program. A counter for generating each random n (n: 1 or the like) is a software counter formed in the RAM 255. “Formed in the RAM 255” means an area of the RAM 255.

In this embodiment, the random 2-1 is not created using the random number value of the random number circuit 706. However, the random 2-1 is the same as the random 2-2, 3 and 4. You may create using the random number value of the random number circuit 706 built in the microcomputer 760 for control.
(1) Random 1: Variable display of the first special symbol (or second special symbol) based on the winning of the game ball (first starting winning or second starting entering) to the first starting winning opening or the second starting winning opening To determine whether to generate a big or small hit (for big hit judgment)
(2-1) Random 2-1 (MR2-1): Determines the type of jackpot (probability big hit, sudden probability change big hit, normal big hit) (for jackpot type determination)
(2-2) Random 2-2 (MR2-2): Determines whether or not to reach (for reach determination)
(3) Random 3 (MR3): The type (type) of the variation pattern is determined (for variation pattern type determination)
(4) Random 4 (MR4): A variation pattern (variation time) is determined (for variation pattern determination)
(5) Random 5 (MR5): Determines whether or not to generate a hit based on the normal symbol (for normal symbol hit determination)
(6) Random 6 (MR6): The initial value of random 1 is determined (for determining the initial value of random 1)
(7) Random 7 (MR7): Determine the initial value of random 5 (for determining the initial value of random 5)

  At S33 in the game control process shown in FIG. 25, the game control microcomputer 760 performs (1) big hit determination random number, (2-1) big hit type determination random number, and (5) per normal symbol. Update the counter to generate a random number for determination. That is, they are determination random numbers, and other random numbers are display random numbers (MR2-2, MR3, MR4) or initial value random numbers (MR6, MR7). In order to enhance the game effect, random numbers other than the random numbers (1) to (7) may be used.

  As described above, the jackpot determination random number (1) is not compared with the jackpot determination value, but a value obtained by performing arithmetic processing on the value (becomes MR1) is a jackpot. It is compared with the judgment value.

  In the determination random number update process in S33, the game control microcomputer 760 uses a constant value that is relatively prime to the total number of random 1 in the counter value for generating random 1 (in this embodiment, 19463). ) Is added, and the remainder obtained by dividing by the total number of random 1 is used as a new count value. When the new count value matches the initial value, that is, when the count value makes one round, random 6 The count value is set as a new random count value of 1, and the same value is set as an initial value of random 6. Also, the count value of the counter for generating random 2-1 is incremented by 1, and when the count value reaches 101, the count value is returned to 1. Also, the count value of the counter for generating random 5 is incremented by 1, and when the count value reaches 14, the count value is returned to 3. When the random 5 count value matches the initial value, that is, when the count value makes one round, the random 7 count value is set as the random 5 count value, and the same value is set as the random 5 initial value. Set.

  In the initial value random number update process of S34 (the same applies to S18), the count value of the counter for generating random 6 is incremented by 1, and when the count value reaches 65536, the count value is returned to 0 and random 7 is generated. The count value of the counter is incremented by 1, and when the count value reaches 14, the count value is returned to 3. In the display random number update process of S35 (the same applies to S17), a predetermined value (for example, a random value of the random number circuit 706) is added to the count value of the counter for generating random numbers 2-2, 3, and 4, and the count is performed. When the value exceeds the range shown in FIG. 26, the count value is returned to the range shown in FIG.

  In the present embodiment, the random number corresponding to the first start prize and the random number corresponding to the second start prize are used as a common software random number, but they may be separate random numbers.

  Further, the CPU 256 performs special symbol process processing (S36). In the special symbol process, corresponding processing is executed in accordance with a special symbol process flag for controlling the first special symbol display 208a, the second special symbol display 208b, and the big prize opening in a predetermined order. The CPU 256 updates the value of the special symbol process flag according to the gaming state.

  Next, a normal symbol process is performed (S37). In the normal symbol process, the CPU 256 executes a corresponding process according to the normal symbol process flag for controlling the display state of the normal symbol display 210 and the open / close state of the variable winning ball apparatus 215 in a predetermined order. The CPU 256 updates the value of the normal symbol process flag according to the gaming state.

  Further, the CPU 256 performs a process of sending an effect control command to the effect control microcomputer 310 (effect control command control process: S38).

  Further, the CPU 256 performs information output processing for outputting data such as jackpot information, start information, probability variation information supplied to the hall management computer (S39).

  Further, the CPU 256 executes prize ball processing for setting the number of prize balls based on detection signals from the first start port switch 213a, the second start port switch 214a, and the count switch 223 (S40). Specifically, the payout control micro board mounted on the payout control board 237 according to the winning detection based on any one of the first start port switch 213a, the second start port switch 214a and the count switch 223 being turned on. A payout control command (prize ball number signal) indicating the number of prize balls is output to the computer. The payout control microcomputer drives the ball payout device 297 in response to a payout control command indicating the number of winning balls.

  In this embodiment, a RAM area (output port buffer) corresponding to the output state of the output port is provided. However, the CPU 256 relates to on / off of the solenoid in the RAM area corresponding to the output state of the output port. Is output to the output port (S41: output processing).

  Further, the CPU 256 performs a special symbol display control process for setting special symbol display control data for effect display of the special symbol in the output buffer for setting the special symbol display control data (S42). The CPU 256, for example, until the end flag is set when the start flag set in the special symbol process is set, or the value of the special symbol process flag set in the special symbol process is changing the special symbol. If the fluctuation speed is 1 frame / 0.2 seconds in the period indicated by, the value of the display control data set in the output buffer is incremented by 1 every 0.2 seconds. Further, the CPU 256 outputs a drive signal in S32 in accordance with the display control data set in the output buffer, whereby the first special symbol and the first special symbol on the first special symbol display 208a and the second special symbol display 208b. 2 Perform variable display of special symbols.

  Further, the CPU 256 performs a normal symbol display control process for setting the normal symbol display control data for performing the effect display of the normal symbol in the output buffer for setting the normal symbol display control data (S43). For example, the CPU 256 sets the value of the normal symbol process flag until the end flag is set when the start flag related to the variation of the normal symbol is set in the normal symbol process or until the end flag is set. If the fluctuation speed of the normal symbol is a speed that switches the display state (“O” and “X”) every 0.2 seconds in the period indicating the fluctuation, every 0.2 seconds elapses. The value of the display control data set in the output buffer (for example, 1 indicating “◯” and 0 indicating “x”) is switched. Further, the CPU 256 executes a normal symbol effect display on the normal symbol display 210 by outputting a drive signal in S32 according to the display control data set in the output buffer.

  Thereafter, the interrupt permission state is set (S44), and the process ends.

  With the above control, in this embodiment, the game control process is started every 2 ms. The game control process corresponds to the processes of S30 to S44 in the timer interrupt process. In this embodiment, the game control process is executed by the timer interrupt process. However, in the timer interrupt process, for example, only a flag indicating that an interrupt has occurred is set, and the game control process is performed by the main process. It may be executed in step (b).

  FIG. 27 is an explanatory diagram showing how to generate random (MR1) to be compared with the big hit determination value. As shown in FIG. 27A, when a game ball wins the first start winning opening 213, that is, when the first start win occurs, the CPU 256 receives the counter circuit 711 via the first latch circuit 714. Read the count value. Also, random 1 is extracted. That is, the count value is read from a counter for generating random 1 (a software counter having the same bit width (for example, 16 bits) as the bit width of the counter circuit 711). Then, the count value read from the counter circuit 711 and the extracted random 1 are added, and the addition value is divided by 65536 (corresponding to the total number of values from 0 to 65535, in other words, equivalent to 65535 + 1) (as an integer). And the remainder (remainder) is defined as MR1 (a random number that is actually compared with the jackpot determination value).

  As shown in FIG. 27B, when a game ball wins the second start winning opening 214, that is, when a second start win occurs, the CPU 256 counters via the second latch circuit 715. The count value of the circuit 711 is read. Also, random 1 is extracted. That is, the count value is read from a counter (software counter) for generating random 1. Then, the count value read from the counter circuit 711 and the extracted random 1 are added, and the addition value is divided by 65536 (corresponding to the total number of values from 0 to 65535, in other words, equivalent to 65535 + 1) (as an integer). And the remainder (remainder) is MR1.

  In FIG. 27C, the reach determination random number (MR2-2), the variation pattern type determination random number (MR3), and the variation pattern determination random number (MR4) corresponding to the random numbers for determining the production mode are generated. It shows how. The CPU 256 reads the random number value from the random number circuit 706 when the random number update timing is reached (corresponding to the execution timing of the processing of S17 in FIG. 24 and S35 in FIG. 25).

  Then, the random number value read from the random number circuit 706 is added to the count value of a counter (software counter) for generating random 2-2. Further, the random number value read from the random number circuit 706 is added to the count value of a counter (software counter) for generating random 3 as an added value. Furthermore, the random number value read from the random number circuit 706 is added to the count value of a counter (software counter) for generating random 4 as an added value. In each case, the value after the addition processing remains in the software counter.

  The CPU 256 reads a count value from a counter (software counter) for generating random 2-2 at a predetermined random number extraction timing to obtain MR2-1, and counts from the counter (software counter) for generating random 3 Is read as MR3, and a count value is read from a counter (software counter) for generating random 4 as MR4.

  FIG. 27D shows another example of how to generate a random number for determining the production mode. In the example shown in FIG. 27D, the ROM 254 stores a numerical value conversion table. In the numerical value conversion table, numerical values corresponding to the respective values in the range of random values (for example, 0 to 65535) that can be output by the random number circuit 706 are set. The CPU 256 reads a random number value from the random number circuit 706 at a predetermined random number extraction timing, reads a numerical value corresponding to the read random number value from the numerical value conversion table, uses the numerical value read from the numerical value conversion table as an addition value, and randomly selects 2-2. Is added to the counter for generating random 3, the counter for generating random 3, and the counter for generating random 4. FIG. 27D shows an example in which a numerical value is read from the numerical value conversion table using the random number value read from the random number circuit 706 as an address, but such a reading method is not essential.

  In the example shown in FIGS. 27C and 27D, the game control microcomputer 760 adds a random number value read from the random number circuit 706 or a value read from the numerical value conversion table to the software counter. The execution part reads the random number value from the random number circuit, determines the addition value based on the read random number value, and adds the determined addition value to the numerical value stored in the software counter as the numerical value storage means Corresponds to means.

  In this embodiment, for MR1 (random number to be compared with the big hit determination value), a predetermined calculation is performed using the count value of the hardware counter and the count value of the software counter created inside the game control microcomputer 760. The random number is generated according to the above, but the big hit type determining random number for determining the big hit type, the normal symbol determining random number for determining whether or not to generate a hit based on the normal symbol, etc. (FIG. 26). For example, a random number may be generated by a predetermined calculation using the count value of the hardware counter and the count value of the software counter. Furthermore, if there are multiple types of jackpot game rounds (for example, 7 rounds and 15 rounds) and the number of rounds is determined by lottery, random numbers used for the lottery (round number determination random number) For the above, a random number may be generated by a predetermined calculation using the count value of the hardware counter and the count value of the software counter.

  Further, in this embodiment, as shown in FIG. 22, the count value of one counter circuit 711 is input to a plurality of latch circuits. However, the counter circuit corresponds to each of the latch circuits. It may be provided. Further, as shown in FIG. 22, the detection signals of the first start port switch 213a and the second start port switch 214a are the latch signals for the first latch circuit 714 and the second latch circuit 715. May be output from the game control microcomputer 760. In this case, when the CPU 256 inputs a detection signal from the first start port switch 213a, it outputs a latch signal to the first latch circuit 714, and when it receives a detection signal from the second start port switch 214a. A latch signal is output to the second latch circuit 715.

  In this embodiment, the output wiring of the counter circuit 711 (16 wirings) is directly connected to the latch circuit (the first latch circuit 714 and the second latch circuit 715), but the wiring is shifted and connected. You may do it. Note that “connect as it is” means that the wiring of the bit n (n: 0 to 15) of the counter circuit 711 is connected to the input of the bit n of the latch circuit. That is, wiring is performed so that the same value as the count value output from the counter circuit 711 is latched by the latch circuit. “Connect the wirings by shifting” means that among the 16 wirings from the counter circuit 711, the wiring of the bit i (i: any of 0 to 15) is the bit j (j: 0 to 15 of the latch circuit). (I ≠ j). Note that two or more wirings that are connected in a shifted manner may be used. The output of the latch circuit is input to the CPU 256 via the input port (a part of the I / O port unit 257 shown in FIG. 21) in the game control microcomputer 760. However, the output between the counter circuit 711 and the latch circuit Instead of shifting the wiring, the wiring between the latch circuit and the input port may be shifted and connected. In any case, the count value output from the counter circuit 711 and the value input to the CPU 256 are not the same, and the value changes randomly instead of stepping one by one. It becomes more difficult to aim at a specific value.

  When MR1 is created, the value of a refresh register (register for refreshing DRAM) built in the game control microcomputer 760 may be used instead of random 1 which is a software random number. Also in this case, the range of values acquired from the refresh register is made the same as the numerical range of the count of the counter circuit 711 (in this example, the numerical range represented by 16 bits).

  FIG. 29 is a flowchart showing random number generation processing (processing for generating MR1). In the random number generation process, the CPU 256 checks whether the value of the start port pointer is “first” (S51). When the value of the start port pointer is “first”, the CPU 256 reads the count value from the first latch circuit 714 (S52). That is, the count value of the counter circuit 711 latched by the first latch circuit 714 is read. When the value of the start port pointer is “second”, the CPU 256 reads the count value from the second latch circuit 715 (S53).

  Then, the CPU 256 compares the count value read from the first latch circuit 714 or the second latch circuit 715 with the stored value. The stored value is a value stored in the RAM 255 and a count value read from the first latch circuit 714 or the second latch circuit 715 last time. When the count value read from the first latch circuit 714 or the second latch circuit 715 is not the same value as the stored value, that is, when the previously read count value is not the same as the current read count value (the count value of the counter circuit 711) Means stepping up) (S54), the process proceeds to S60.

  When the count value read from the first latch circuit 714 or the second latch circuit 715 is the same value as the stored value (meaning that the count value of the counter circuit 711 is not advanced), it is formed in the RAM 255. The value of the counter for the number of unrunning steps is incremented by one (S55). Then, when the value of the non-stepping number counter reaches a predetermined value (for example, 10) (S56), control is performed to transmit an abnormality notification start designation command to the effect control microcomputer 310 (S57). Also, an abnormality notification flag is set (S58).

  In S60, the CPU 256 checks whether or not the abnormality notification flag is set. If the abnormality notification flag is not set, the process proceeds to S63. If the abnormality notification flag is set, the abnormality notification flag is reset (S61), and control for transmitting an abnormality notification end designation command to the effect control microcomputer 310 is performed (S62). When the abnormality notification flag is set, the fact that the count value of the counter circuit 711 is stepping up (S54, S60) confirms that the counter circuit 711 is operating normally after being determined to be abnormal. As a result, the CPU 256 performs the processes of S61 and S62.

  Then, the CPU 256 clears (sets to 0) the value of the unrunning number counter (S63), and proceeds to S59.

  In S59, the CPU 256 stores the count value read from the first latch circuit 714 or the second latch circuit 715 in the process of S52 or S53 in the RAM 255 as a saved value.

  Then, random 1 is extracted (S64), and the count value read from the first latch circuit 714 or the second latch circuit 715 in the process of S52 or S53 and random 1 are added (S65). The range that can be taken by the random 1 is 0 to 65535 (see FIG. 26), and the range that the count value of the counter circuit 711 can take is also 0 to 65535.

  Then, the CPU 256 performs an operation of dividing the added value (processing result of S65) by 65536, and sets the remainder as the calculated value (S66). The range that the calculation value can take is 0 to 65535.

  Then, the CPU 256 stores the value obtained in the process of S66 as MR1 in the storage area in the reserved storage buffer indicated by the start port pointer of the first reserved storage buffer 151A and the second reserved storage buffer 151B. The process is executed (S67). Specifically, since the start port pointer indicates “first”, the CPU 256 stores the software random number in the storage area corresponding to the value indicated by the first reserved storage number counter of the first reserved storage buffer 151A.

  Next, display effects in the gaming machine of this embodiment will be described. In the first special symbol display device 208a and the second special symbol display device 208b, when a predetermined time elapses after the variable symbol special display is started, the stop symbol which is the variable symbol variable display result is stopped and displayed (derived display). To do. If it is decided to win, a special special symbol (big hit symbol) is stopped and displayed. When it is decided to make a small hit, a predetermined special symbol (small hit symbol) different from the big hit symbol is stopped and displayed. If it is determined to be off, special symbols other than the big hit symbol and the small hit symbol are stopped and displayed. When the big hit symbol is derived and displayed, the gaming state is controlled to the big hit gaming state as the specific gaming state. Further, when the small hit symbol is derived and displayed, the small hit game state different from the big hit game state is controlled. In this embodiment, as an example, the numbers indicating “1”, “3”, and “7” are big hit symbols, the numbers indicating “5” are small hit symbols, and the symbol indicating “−” is an off symbol. . The big hit symbol, the small hit symbol, and the off symbol in the variable display of the special symbol by the first special symbol display 208a may be different from the symbols in the variable display of the special symbol by the second special symbol display 208b. It may be good or common in variable display of both special symbols.

  In the present embodiment, among the special symbols indicating the numbers “1”, “3”, and “7” that are the jackpot symbols, the special symbols indicating the numbers “3” and “7” are set as the 15-round jackpot symbol. The special symbol indicating the number “1” is made a big hit symbol for two rounds. When the 15-round big hit symbol is stopped and displayed on the special symbol display, the opening / closing plate in the special variable winning ball device 220 has a predetermined period (for example, 29 seconds) or a predetermined number (for example, 10) of winning balls. During the period until the occurrence, a round is started in which the special variable winning ball apparatus 220 is changed to the first state advantageous to the player, being in an open state. In the 15 round big hit state, the number of rounds is the first number (for example, 15). Hereinafter, the jackpot gaming state in which the number of rounds is the first number is also referred to as 15 rounds jackpot state.

  In addition, when the 2-round jackpot symbol is stopped and displayed on the special symbol display, the game shifts to a jackpot gaming state (two-round jackpot state) in which the number of rounds is the second number (for example, “2”). In the 2 round big hit state, the period of each round becomes a short second period (for example, 0.5 seconds) due to the first period in the 15 round big hit state. In the 2 round big hit state, the number of executions of the round is a second number (for example, “2”) which is smaller than the first number in the 15 round big hit state. In addition, in the 2 round big hit state, at least one of the period in which the winning opening is opened in each round is the second period and the number of executions of the round is the second number is performed. It suffices to be controlled as follows. In the two-round big hit state, the predetermined winning ball apparatus provided separately from the special variable winning ball apparatus 220 in each round is changed from the second state which is disadvantageous for the player to the first state which is advantageous for the player. It is also possible to return to the second state after a predetermined period (first period or second period) has elapsed.

  In addition, when it is determined that the gaming state is controlled to the time-saving state after the big hit gaming state is ended, the special symbol stop symbol is “3”. In the short time state, the variation time of the special symbol in the variable display of the special symbol is shortened compared to the normal state (the state that is not the probability variation state or the short time state). The time-saving state is, for example, when one of the following conditions is satisfied: the variable display of a special symbol is executed a predetermined number of times (for example, 100 times) and the variable display result is “big hit” To finish. In addition, after the big hit state that is executed after the special symbol showing the number “3” out of the 15 round big hit symbols is stopped and displayed as a stop symbol in the variable display of the special symbol, the normal state is set without the time reduction state. You may make it become. The jackpot symbol that is derived and displayed when the game is controlled to the short-time state or the normal state after the jackpot gaming state is finished is called a normal jackpot symbol or a non-probable variable jackpot symbol (non-probable variation symbol).

  If the game state is decided to be controlled to the probable state after the big hit game state is ended, the special symbol stop symbol becomes “7”. The probability variation state continues until, for example, a jackpot symbol is derived and displayed as a variable display result. In addition, when one of the conditions is established first, the variable display of the special symbol is executed a predetermined number of times (for example, 100 times) and the jackpot symbol is derived and displayed as a variable display result. The probability variation state may be terminated. Further, a special symbol stop symbol derived and displayed when it is determined to control the gaming state to the probability variation state is referred to as probability variation big hit symbol or probability variation symbol.

  Even after the two-round big hit state is over, the gaming state is controlled to the probability change state (high probability state). The probability variation state controlled after the end of the two round big hit state is also referred to as a sudden probability variation (surprise) state.

  When the small hit symbol is stopped and displayed on the special symbol display, the gaming state is controlled to a small hit gaming state different from the big hit gaming state. In the small hit game state, similarly to the two round big hit state, the open / close plate in the special variable winning ball apparatus 220 is opened for the second period, and the big winning opening is opened. The number of rounds is the second number (for example, 2). However, unlike the two round big hit state, the gaming state is not changed. That is, the gaming state before being controlled to the small hit gaming state continues. However, when it is decided to end the probability change state or the time-short state, the gaming state is controlled to the normal state after the small hit gaming state is ended. When the winning ball apparatus provided separately from the special variable winning ball apparatus 220 in each round in the two round big hit state is changed to the first state, even in the small hit gaming state, Similarly, the winning ball apparatus is changed to the first state.

  Further, in the probability variation state, the probability of determining the big hit is higher than in the low probability state (normal state). For example, it is 10 times. Specifically, in the probability variation state, the number of determination values determined to be a big hit when it matches the value of the random number for jackpot determination is 10 times that in the normal state. In addition, the probability that the stop symbol of the normal symbol display 210 becomes a winning symbol is increased. That is, the second start winning opening 214 is easily opened, and the start winning is likely to occur. Specifically, in the probability variation state, the number of determination values determined to be a hit when it matches the value of the random number for normal symbol determination is larger than that in the normal state. Further, in addition to increasing the probability that the stop symbol of the normal symbol display 210 becomes a winning symbol, the number of opening or the opening time of the variable winning ball device 215 is increased, or the number of opening and the opening time of the variable winning ball device 215 is increased. You may increase more. Further, even in the short-time state, the probability that the stop symbol of the normal symbol display 210 becomes a winning symbol is increased, the number of opening or the opening time of the variable winning ball device 215 is increased, the number of opening and opening of the variable winning ball device 215 is increased. You may spend more time.

  In the display area of the effect display device 209, variable display of decorative symbols is performed in response to variable display of special symbols by the first special symbol display 208a and the second special symbol display 208b. That is, in the display area of the effect display device 209, each of the “left”, “middle”, and “right” symbol display areas 209L, based on which one of the first start condition and the second start condition is satisfied, In 209C and 209R, the variation of the decorative symbol is started. For example, the stop symbol of the decorative symbol is stopped and displayed (derived display) in the order of “left” → “right” → “middle”. Note that the decorative symbols may be stopped and displayed in a predetermined order in the “left”, “middle”, and “right” symbol display areas 209L, 209C, and 209R, and each of the “left”, “middle”, and “right” The stop symbols may be stopped and displayed simultaneously in the symbol display areas 209L, 209C, and 209R.

  The period (variable display period) from the start of variable display of decorative symbols until the stop symbols are derived and displayed in the “left”, “middle”, and “right” symbol display areas 209L, 209C, and 209R. The variable display state of symbols may be a predetermined reach state. The reach state is a display state in which the decorative symbols that are not yet stopped when the decorative symbols that are stopped and displayed in the display area of the effect display device 209 form part of the jackpot combination continue to change, or This is a display state in which all or part of the decorative symbols change synchronously while constituting all or part of the jackpot combination. The display effect in the reach state is reach effect display (reach effect).

  In addition, during the variable display of decorative designs, unlike the reach effect, it is possible that the variable display state of decorative designs may be in the reach state and that the variable display result may be a big hit design. A specific effect may be executed for notifying the player by a variable display mode of the symbol. In this embodiment, specific effects such as “slip”, “pseudo train”, “intro”, “expansion chance”, “end of development opportunity” can be executed.

  In the specific effect of “slip”, two or more symbol display areas (for example, “left”) are displayed after the decorative symbols are changed in the symbol display areas 209L, 209C, and 209R of “left”, “middle”, and “right”. In addition, after the decorative symbols are temporarily stopped and displayed in the “right” symbol display areas 209L and 9R), a predetermined number (for example, “1” or “2”) of the symbol display areas in the temporarily stopped symbols are displayed. The decorative symbol to be stopped and displayed is changed by changing the decorative symbol again after changing the decorative symbol again (for example, one or both of the “left” symbol display area 209L and the “right” symbol display area 209R). An effect display is performed. In addition, informing the player that the decorative symbol that has been stopped and displayed will not be finalized (final stop) by, for example, displaying fluctuation fluctuation in the temporary stop display or changing the decorative symbol again after a short temporary stop. Is preferred. Alternatively, the decorative design may be temporarily changed to such an extent that the player recognizes that the decorative display that has been stopped is confirmed, and then the decorative design may be changed again.

  In the “pseudo-ream” specific production, “Left”, “Middle”, “Right” are selected based on the fact that one of the first start condition and the second start condition of the variable symbol variable display is satisfied once. After changing the decorative symbols in the symbol display areas 209L, 209C, and 209R, after temporarily displaying the decorative symbols in all the symbol display areas 209L, 209C, and 209R, the decorative symbols are displayed in all the symbol display areas 209L, 209C, and 209R. The effect display for changing the symbol again (pseudo continuous fluctuation) is performed a predetermined number of times (for example, up to four times).

  The ROM 254 in the game control microcomputer 760 stores various data tables used for controlling the progress of the game, in addition to the game control program. For example, table data constituting a plurality of determination tables and determination tables prepared for the CPU 256 to perform various determinations and determinations are stored. Further, the ROM 254 constitutes a variation pattern table that stores a plurality of types of table data constituting a plurality of command tables used for the CPU 256 to transmit various control commands from the main board 231 and a plurality of types of variation patterns of decorative symbols. Table data etc. are stored.

  The determination table stored in the ROM 254 includes, for example, a special symbol display result determination table 330 shown in FIG. The special symbol display result determination table 330 derives stop symbols that are variable display results in the variable display of the first special symbol on the first special symbol display 208a and the variable display of the second special symbol on the second special symbol display 208b. Before being displayed, whether the variable display result is a big hit symbol and controlled to a big hit gaming state, whether the variable display result is a small hit symbol and controlled to a small hit gaming state, It is a table referred to for determination based on the random number MR1 for display result determination. The special symbol display result determination table 330 compares the value with the value of the random number MR1 for determining the display result of the special symbol, depending on whether or not the probability variation flag is set (whether it is off or on). The determination value associated with the big hit, the small hit, and the loss is set.

  The determination table stored in the ROM 254 includes a jackpot type determination table 331 shown in FIG. When it is determined that the variable display result is a jackpot symbol, the jackpot type determination table 331 determines whether the decorative symbol variable display mode is “normal” or “first” based on the random number MR2-1 for determining the jackpot type. It is a table that is referred to in order to determine one of a plurality of types of jackpot types from “1 probability variation” to “third probability variation” and “surprising accuracy”. In the jackpot type determination table 331, a numerical value (to be compared with the value of the random number MR2-1 for jackpot type determination depending on whether or not the first special symbol variation flag indicating the variation of the first special symbol is set. Determination values) corresponding to the jackpot types of “normal”, “first probability variation” to “third probability variation”, and “rush probability” are set.

  In the big hit type determination table 331 shown in FIG. 30, the assignment of the determination value to the big hit type of “surprise” differs depending on whether or not the first special symbol fluctuation flag indicating the fluctuation of the first special symbol is set. Yes. That is, when the first special symbol variation flag is set, the value in the range of “83” to “100” corresponds to the big hit type “surprise”, and the first special symbol variation flag is not set. In the case (indicating the variation of the second special symbol), no judgment value is assigned to the big hit type of “surprise”. With such setting, the jackpot type is determined as one of a plurality of types based on the fact that the first start condition for starting variable display of the first special symbol on the first special symbol display 208a is satisfied. And a case where the jackpot type is determined as one of a plurality of types based on the fact that the second start condition for starting variable display of the second special symbol on the second special symbol display 208b is established. The ratio at which the jackpot type is determined to be “surprise” can be varied.

  In the example shown in FIG. 30, when the variable display of the first special symbol is performed based on the second start winning prize, the determination value is not suddenly assigned. Therefore, in the probability variation state in which the second start winning opening 214 has many opportunities to open (including a long opening period), it is possible to reduce the ratio that is determined suddenly. Therefore, in the situation that is already in the probabilistic state, it is possible to reduce the possibility that a surprise that will be shifted to the probable state occurs and the interest of the game given to the player is reduced.

  The determination value is a numerical value to be compared with the extracted random number value (random number value). If the random value matches any of the determination values, it corresponds to the determination value (the determination value is assigned). A gaming state or the like is determined. For example, it is determined to execute an effect corresponding to the determination value.

  As described above, in the pachinko gaming machine 201 of the present embodiment, every time the random 1 makes one round, the initial value that is the starting point of the next cycle is determined and determined based on the random 6 that is the initial value determining random number. Since the update of random 1 is started from the initial value, and the starting point of the next cycle changes every time random 1 makes one round, the timing at which random 1 becomes a specific value is specified Difficult to do.

  In particular, in this embodiment, since the above random 1 is used to create MR1 which is a random number used for jackpot determination in which it is determined whether or not to shift to a jackpot gaming state advantageous to the player, It is possible to prevent a game from being played aiming at the timing at which MR1 that coincides with the judgment value of the jackpot gaming state that greatly affects profits is generated.

  In this embodiment, every time the random 1 makes one round, the initial value of the random 1 is changed using the random number for determining the initial value (random 6). A configuration for changing the initial value of random 1 using a random number for determination (random 6), and a configuration for changing the initial value of random 1 using a random number for determining initial value (random 6) every time random 1 is updated a predetermined number of times Further, the initial value of random 1 may be changed using a random number for determining an initial value (random 6) every predetermined time.

  Further, the initial value determining random number at the time when the initial value determining random number (random 6) makes one round is used as it is as the initial value of random 1, but the initial value determining point at the time when the initial value of random 1 makes one round is used. An operation value obtained by performing a predetermined operation on the initial value determination random number, such as a value obtained by adding or subtracting a specific value to the random number, may be used as the initial value of random 1.

  Random 1 is updated by adding a certain value that is relatively prime to the total number of random 1 and then dividing the remainder by the total number of random 1 to new random 1 It is preferable that the updated random number is not continuous with the random number before the update and can have periodicity. However, the periodicity can be improved by adding or subtracting one by one like other random numbers. You may make it have.

  In addition, the range of random 6 for determining the initial value of random 1 is 0 to 65535, which is the same as the range of random 1, and the initial value of random 1, that is, the starting point of the next cycle can vary over all numerical ranges of random 1. Therefore, it is preferable because it is difficult to specify the initial value of random 1, but a random number in a range different from the numerical range of random 1 may be applied as random 6.

  In addition, random 1 is updated regularly (every 2 ms), while random 6 is updated even in a period in which timer interruption processing is not executed in addition to the periodic update. ing. That is, since the update frequencies of random 1 and random 6 are different, the initial value of random 1 can be prevented from being biased to a specific range.

  In this embodiment, the clear switch is operated when the power is turned on, and even when the control state before power interruption is initialized, the value of the software random number before power interruption is maintained and before power interruption. The value obtained by the calculation using both random 1 and random 6 is set as the initial value of random 1, and update of random 1 is started from the set initial value. Since the starting point for starting the update of random 1 also varies, it becomes more difficult to specify the timing at which MR1 compared with the big hit determination value from random 1 becomes a specific value.

  In addition, when the control state before power interruption is initialized with the operation of the clear switch at power-on, the value obtained by the calculation using both random 1 and random 6 before power interruption is used as the starting point. After the first update of random 1 is made, the initial value of random 1 that is the starting point of the next cycle is determined, and then the initial value of random 1 is changed every time random 1 makes one turn. When the control state before power interruption is initialized in accordance with the operation of the clear switch, the random 1 with an equal period is used. It is possible to make a big hit judgment and to ensure the fairness of the game.

  In the present embodiment, every time the random 1 makes one round, the initial value of the random 1 is changed using the random number for determining the initial value (random 6). A configuration in which the initial value of random 1 is changed using an initial value determining random number (random 6), and the initial value of random 1 is changed using an initial value determining random number (random 6) every time random 1 is updated a predetermined number of times The initial value of random 1 every time random 1 is updated for a predetermined period other than one round, such as a configuration of changing the initial value of random 1 using a random number for determining an initial value (random 6) every predetermined time In such a configuration, after the power is turned on, random 1 update is started for a predetermined period, and after random 1 is updated, an initial value determination random number (every predetermined period) Random 1 using random 6) By so changing the initial value, it is possible to perform the jackpot determined using the random one equivalent period.

  In the present embodiment, all stored data in the RAM 255 is retained when the power is interrupted. However, when a configuration is employed in which only the data necessary for restoration is retained among the stored data in the RAM 255 when the power is interrupted. As described above, the initial value of random 1 that becomes the starting point of the next cycle after one round of updating of random 1 starts from the value obtained by the calculation using both random 1 and random 6 before power interruption After that, the random 1 initial value is changed every time the random 1 makes one round, so that it is not necessary to hold the initial value of the random 1 at the time of power interruption. The capacity of backup data to be reduced can be reduced.

  Further, in this embodiment, when the control state before power interruption is initialized in accordance with the operation of the clear switch at power-on, it is obtained by calculation using both random 1 and random 6 before power interruption. Value, that is, a value calculated using a plurality of data held before power interruption is set as an initial value of random 1, and MR1 that is a random number used for jackpot determination is specified from random 1 It is preferable because it becomes more difficult to specify the timing at which the value becomes, but a value obtained by calculation using either random 1 or random 6 before power interruption is set as the initial value of random 1 You may do it.

  Further, in this embodiment, when the control state before power interruption is initialized in accordance with the operation of the clear switch at power-on, it is obtained by calculation using both random 1 and random 6 before power interruption. The random value is set as random 6, and the update of random 6 is started from the set value. Since the starting point for starting the update of random 6 after the power is turned on varies, It becomes difficult to specify the initial value.

  When the control state before power interruption is initialized by the operation of the clear switch at power-on, the value obtained by the calculation using both random 1 and random 6 before power interruption, that is, power The value calculated using a plurality of data held before the interruption is set as random 6, which is preferable because it is difficult to specify the initial value of random 1, You may make it set the value obtained by the calculation using either one of the random 1 or random 6 before interruption as the random 6.

  In this embodiment, the initial value of random 1 obtained by calculation using both random 1 and random 6 before power interruption is used as random 6, and a program for calculating random 6 Therefore, the program capacity can be reduced.

  In this embodiment, the initial value of random 1 obtained by calculation using both random 1 and random 6 before power interruption is used as random 6, but for calculating the initial value of random 1 Even when the configuration is such that the random 6 is calculated using the same calculation program as the calculation, the calculation program for calculating both of them can be shared, so that the program capacity can be reduced.

  Further, in this embodiment, when returning to the control state before power interruption when power is turned on, update of random 1 and random 6 is started from the value maintained from before power interruption, and random 1 is before power interruption. It is determined that the circuit has made one revolution by reaching the initial value maintained from the beginning, and the initial value of the next cycle is determined based on random 6, and it returns to the control state before power interruption when the power is turned on. In this case, the update of random 1 and random 6 will also be resumed from the control state before the power interruption, and when returning to the control state before the power interruption, the random 1 and random 6 will also be in the state before the power interruption. Therefore, the continuity of the control state before power interruption and after return can be ensured.

  In addition, when the power is turned on, the method for determining the value for starting update of random 1 and random 6 is different between when the control state before power interruption is initialized and when the control state before power interruption is restored. Therefore, it becomes more difficult to specify the timing at which MR1 which is a random number used for jackpot determination from random 1 becomes a specific value and to specify the initial value of random 1.

  In the present embodiment, when the control state before power interruption is initialized in accordance with the operation of the clear switch at power-on, it is obtained by calculation using random 1 maintained from before power interruption. If the value is set as the initial value of random 1, update of random 1 is started from the set value, and when returning to the control state before power interruption when power is turned on, random from the value maintained before power interruption 1 update is started, but when the control state before power interruption is initialized with the operation of the clear switch, random 1 update is started from the value maintained before power interruption, A value obtained by calculation using random 1 maintained before power interruption when power is turned on may be set as an initial value of random 1, and update of random 1 may be started from the set value. Furthermore, after the power is turned on, the control state before power interruption is initialized in response to the operation of the clear switch, or the control state before power interruption is restored when the power is turned on. A value obtained by calculation using random 1 maintained before power interruption may be set as an initial value of random 1, and update of random 1 may be started from the set value.

  Further, in the present embodiment, the random number used for the jackpot determination is a value obtained as a result of an operation using a hard random number generated by the counter circuit 711 and a random number 1 which is a software random number generated by software. Since MR1 is used, it becomes more difficult to specify the timing at which MR1 which is a random number used for jackpot determination becomes a specific value.

  Even if the counter circuit 711 outputs an illegal act that does not change the count value, MR1 which is a random number used for jackpot determination by the random 1 created by software is in the same range of 0 to 65535 as the counter circuit 711. Therefore, MR1 can be generated randomly by random 1 that changes at least in the same numerical range (the same numerical range of MR1) as the numerical value range of the count value output by counter circuit 711. Even in this case, it is difficult to specify the timing at which MR1, which is a random number used for jackpot determination, takes a specific value. That is, even if the count value output from the counter circuit 711 is fixed (the count value does not change), the result of the operation performed on the random 1 that changes within the same numerical range as the counter circuit 711 is 0 to It becomes a random value within the range of 65535, and measures against such illegal acts can be taken.

  Also, random 1 is updated by adding a certain value that is relatively prime to the total number of random 1 and then dividing the remainder by the total number of random 1 to new random 1 Since the random number after the update is not continuous with the random number before the update, sufficient randomness can be ensured even with only random 1, so that the counter circuit 711 does not change the count value output by the counter circuit 711 as described above. However, it becomes more difficult to specify the timing at which MR1, which is a random number used for jackpot determination, takes a specific value.

  In addition, in FIG. 29 and the like, a plurality of determination values are shown as continuous numerical values (0 to 109 in FIG. 29, etc.), but actually, the plurality of determination values are jumped in a predetermined numerical range. Assigned as a value (discrete value). If the plurality of determination values are discrete values, the burden on the determination processing of the CPU 256 (processing for determining whether there is a determination value that matches the random number) increases, but it is effective as a countermeasure against fraud. .

  In the present embodiment, the random number used for the jackpot determination is a value obtained as a result of an operation using a hard random number generated by the counter circuit 711 and a random number 1 which is a software random number generated by software. Although it is used as MR1, the random 1 itself of this embodiment may be used as MR1 without using a hard random number, or it is obtained as a result of an operation using the random 1 of this embodiment and another software random number. The value obtained may be used as MR1.

  In the present embodiment, the random value 5 for normal symbol determination is also determined by the initial value being determined based on the random value 7 for determining the initial value each time one round is made, as in the case of the random 1. While the initial value changes with each turn, when it is initialized with the operation of the clear switch when the power is turned on, the random 5 count value and initial value are not newly set, and the power The update is resumed from the value before the interruption, but as with random 1, the value obtained by the calculation using random 5 and / or random 7 maintained before the interruption is random 5 By newly setting the count value and its initial value, the update of random 5 may be started from the set value.

  Also, the random 2-1 used for determining the big hit type, the random 2-2 used for reach determination, the random 3 used for determining the variation pattern type, and the random 4 used for determining the variation pattern are also the initial values as with the random 1 A random number counter for determination may be provided, and the initial value may be changed each time the random numbers make one round.

  In this case, similarly to random 1, a value obtained by performing a calculation using a random number maintained before power interruption at the time of power-on and / or a corresponding random number for initial value determination, By setting each new random number and its initial value and starting updating from the set value, it becomes difficult to specify the timing at which each random number becomes a specific value.

  As described above, the second embodiment of the present invention has been described with reference to the drawings. However, the present invention is not limited to this embodiment, and modifications and additions within the scope of the present invention are included in the present invention. Needless to say.

  For example, the embodiment 2 includes variable display means that can variably display a plurality of types of identification information that can identify each of them, and after a predetermined variable display execution condition is satisfied, Based on the establishment, the variable display means starts the variable display of the identification information, and when the display result of the variable display of the identification information becomes the specific display result, the gaming machine (transition to a specific gaming state advantageous to the player ( Hereinafter, the model A) is exemplified, but the gaming machine according to the present invention is not limited to such a gaming machine, and the gaming machine does not have “variable display means capable of variably displaying identification information”. Applicable. In other words, the variable winning device is released a predetermined number of times by winning in a predetermined start winning area, and when the game medium that has won the variable winning apparatus through the opening passes through the specific area (V area), it enters a specific gaming state (big hit state). The present invention can also be applied to a controlled gaming machine (hereinafter referred to as model B).

  Further, the present invention can be applied to a mixed type model of model A and model B. In other words, variable display means is provided that can variably display a plurality of types of identification information that can identify each of them. After a predetermined variable display execution condition is satisfied, variable display is performed based on the satisfaction of the variable display start condition. The variable display of the identification information is started by the means, and when the display result of the variable display of the identification information becomes the specific display result, the control to shift to the specific gaming state advantageous to the player, When the display result becomes a predetermined display result (small hit) different from the specific display result, the variable winning device is released a predetermined number of times, and the game media that has won the variable winning device by the release has a specific region (V region). It may be a gaming machine that executes control to shift to a specific gaming state (big hit state) by passing through.
