A game result is displayed with a result mode other than the result mode (for example, a number such as “3” or “7”) in a lit state.

  The normal display 53 blinks the lamp during the change and displays that the change is in progress. When the game result is “out of”, for example, the lamp is turned off, and when the game result is “hit”, the lamp is turned on to display the game result.

  The special figure 1 hold display 54 displays the number of undigested balls (starting memory number = holding number) among the number of winning balls to the start winning opening 36, which is the variation start condition of the special figure 1 display 51. Specifically, as shown in FIG. 5B, when the number of hold is “0”, all four lamps are turned off, and when the number of hold is “1”, only lamp 1 is turned on. When the number of holdings is “2”, the lamps 1 and 2 are turned on. When the number of holdings is “3”, the lamps 1, 2 and 3 are turned on. When the number of holdings is “4”, 4 is set. All the lamps 1 to 4 are turned on.

  The special figure 2 hold indicator 55 displays the start memory number (= hold number) of the second start winning opening (ordinary variable prize device 37), which is the fluctuation start condition of the special figure 2 indicator 52, and the special figure 1 hold indicator. It is displayed in the same manner as 54 (see FIG. 5B).

  As shown in FIG. 5 (c), the universal map hold display 56 displays the start memory number (= hold count) of the universal map start gate 34, which is the variation start condition of the general map display 53. For example, when the hold number is “0”, the lamps 1 and 2 are turned off, and when the hold number is “1”, only the lamp 1 is turned on. When the number of hold is “2”, lamps 1 and 2 are turned on. When the number of hold is “3”, lamp 1 is blinked, lamp 2 is turned on, and when the number of hold is “4”. Lamps 1 and 2 are blinked.

For example, the first gaming state indicator 57 turns off the lamp in the normal gaming state, and turns on the lamp when the big hit has occurred.
For example, the second gaming state indicator 60 turns off the lamp in the normal gaming state, and turns on the lamp when the time-short state occurs.

  The error indicator 58 turns the lamp off when the jackpot probability state is low when the gaming machine 10 is turned on, and when the jackpot probability state is high when the gaming machine 10 is turned on. Turns on the lamp.

  For example, the round display unit 59 turns off the lamp in the normal gaming state, and turns on the lamp corresponding to the number of rounds (2 rounds or 15 rounds) when the big hit occurs. The round display unit 59 may be configured by a 7 segment type display.

  In the gaming machine 10 of the present embodiment, a game is played by launching a game ball (pachinko ball) from a launcher (not shown) toward the game area 32. The launched game balls flow down the game area 32 while changing the rolling direction by means of direction changing members such as obstacle nails and windmills arranged at various locations in the game area 32, and the normal start gate 34 and the general winning opening 35. The winning prize opening 36, the normal variable prize winning device 37 or the special variable prize winning device 38 is won, or it flows into the out port 39 provided at the bottom of the game area 32 and is discharged from the game area. Then, when a game ball wins the general winning opening 35, the starting winning opening 36, the normal variable winning device 37 or the special variable winning device 38, the number of winning balls corresponding to the type of the winning winning port is given by the payout control device 200. It is discharged from the controlled dispensing unit to the upper plate 21 or the lower plate 23 of the front frame 12.

  On the other hand, a gate switch 34a (see FIG. 3) including a non-contact type switch for detecting a game ball that has passed through the general diagram start gate 34 is provided in the general diagram start gate 34. When a game ball that has been driven into the area 32 passes through the usual figure start gate 34, it is detected by the gate switch 34a and a usual figure change display game is played.

  In addition, the normal variation display game cannot be started, for example, the normal variation display game has already been played and the normal variation display game has not been completed, When 37 is converted to the open state and the game ball passes through the general figure start gate 34, if it is less than the upper limit of the normal figure start memory number, the general figure start memory number is added (+1) and the general figure start memory number is increased. One figure start memory is stored. The number of memorized start prizes is displayed on the memory display unit 56 for notifying the number of start prizes of the collective display device 50.

  In addition, in the normal chart start memory, a random number value for hit determination for determining a hit error of the normal figure fluctuation display game is stored, and when the random number value for hit determination coincides with the determination value In addition, a specific result mode (specific result) is derived by hitting the common map fluctuation display game.

  The usual map change display game is executed by a change display unit (common figure display) 53 provided in the collective display device 50. The general-purpose indicator 53 is composed of LEDs indicating normal identification information (normal diagrams, normal symbols) in the lit state and indicating misalignment in the unlit state, and the normal identification information is displayed by blinking this LED. The fluctuation display is performed, and after a predetermined fluctuation display time has elapsed, the LED is turned on or off to display the result.

  Note that, for example, numbers, symbols, character designs, and the like may be used as the normal identification information, which is displayed by variably displaying for a predetermined time and then stopped. If the stop display of the usual figure change display game is a specific result, the pair of movable members 37b of the normal fluctuation winning device 37 is opened for a predetermined time (for example, 0.3 seconds). It becomes a state. This makes it easier for the game ball to win the second start winning opening inside the normal fluctuation winning device 37, and the number of times the second special figure changing display game is executed increases.

  When the random number value extracted at the time of detection of the passage to the general chart start gate 34 is a winning value, the normal symbol displayed on the universal chart display unit 53 stops in a winning state and enters a winning state. At this time, the normal variation winning device 37 is in a state in which the movable member 37b is opened for a predetermined time (for example, 0.3 seconds) by driving the built-in general-purpose solenoid 37c (see FIG. 3). It is converted and the winning of the game ball is allowed.

  The winning ball to the starting winning port 36 and the winning ball to the normal variation winning device 37 are respectively detected by the starting port 1 switch 36a and the starting port 2 switch 37a provided inside. The game ball that has won the start winning opening 36 is detected as the start winning ball of the first special figure variable display game, is stored up to a predetermined upper limit number (for example, 4), and is awarded to the normal variable winning device 37. The played game balls are detected as start winning balls for the second special figure variation display game, and stored with a predetermined upper limit number (for example, four) as a limit.

  Also, at the time of detecting the starting winning ball, a big hit random number value, a big hit symbol random number value, and each variation pattern random number value are extracted, and the extracted random number value is stored in a special figure in the game control device 100 (see FIG. 3) Each area (a part of the RAM) is stored as a special figure start memory for a predetermined number of times (for example, a maximum of four times). The number stored in the special figure start memory is displayed on the storage display units 54 and 55 for notifying the start winning number of the collective display device 50 and also on the display device 41 of the center case 40.

The game control device 100 uses the special figure indicator (variable display device) 51 or 52 to change the first or second special figure on the basis of the winning entry to the start winning opening 36 or the normal variable prize winning device 37 or the start memory thereof. Play a display game.
The first special figure fluctuation display game and the second special figure fluctuation display game are performed by variably displaying a plurality of special symbols (special figures, identification information) and then stopping and displaying a predetermined result form. In addition, a decorative special figure fluctuation display game for displaying a plurality of types of identification information (for example, numbers, symbols, character designs, etc.) corresponding to each special figure fluctuation display game on the display device 41 is executed. ing.
As a result of the special figure fluctuation display game, when the display mode of the special figure 1 display 51 or the special figure 2 display 52 becomes a special result mode, a special game state (so-called big hit state) ) Correspondingly, the display mode of the display device 41 is also a special result mode.

  In the decorative special symbol variation display game on the display device 41, for example, the decorative special symbol (identification information) composed of the above-described numbers is left (first special symbol), right (second special symbol), middle (third special symbol). The variation display is started in the order of symbols), the symbols that have been varied after a predetermined time are sequentially stopped, and the result of the special symbol variation display game is displayed. In addition, the display device 41 performs a variable display game with a decorative special symbol corresponding to the number of special figure starting memories, and various effect displays such as the appearance of a character are performed to improve interest.

  The special figure 1 display 51 and the special figure 2 display 52 may be separate displays or the same display, but each special figure variation display is performed so as not to be executed independently or simultaneously. The game is displayed. In addition, the display device 41 may use different display devices and different display areas in the first special map variable display game and the second special map variable display game, or use the same display device and display area. However, the decoration special figure variation display game is displayed so as not to be executed independently or simultaneously. The game machine 10 may not be provided with the special figure 1 display 51 and the special figure 2 display 52, and the special figure variation display game may be executed only by the display device 41.

  Further, the second special figure variation display game is executed with priority over the first special figure variation display game. That is, if there is a start memory of the first special figure fluctuation display game and the second special figure fluctuation display game, and the execution of the special figure fluctuation display game becomes possible, the second special figure fluctuation display game is It is supposed to be executed.

  In addition, in the state where the first special figure fluctuation display game (second special figure fluctuation display game) can be started and the number of start memories is zero, the start winning opening 36 (or the normal fluctuation prize winning device 37) is entered. When the game ball wins, the start memory is stored as the start right is generated, the start memory number is incremented by 1, and the first special figure variation display game (second special figure) is immediately added based on the start memory. (Variable display game) is started, and at this time, the start memory number is decremented by one.

On the other hand, a state in which the first special figure fluctuation display game (second special figure fluctuation display game) cannot be started immediately, for example, the first or second special figure fluctuation display game has already been performed, and the special figure fluctuation display game has ended. When the game ball is won in the start winning opening 36 (or the normal variable prize winning device 37) in a state that is not in a special state or in a special game state, the start memory number is 1 if the start memory number is less than the upper limit number. By adding, one start memory is stored. Then, in a state where the starting memory number becomes 1 or more, a state in which the first special figure fluctuation display game (second special figure fluctuation display game) can be started (the end of the previous special figure fluctuation display game or the special game state) (End), the start memory number is decremented by 1, and the first special figure fluctuation display game (second special figure fluctuation display game) is started based on the stored start memory.
In the following description, when the first special figure fluctuation display game and the second special figure fluctuation display game are not distinguished, they are simply referred to as a special figure fluctuation display game.

  Although not particularly limited, the starting port 1 switch 36a in the starting winning port 36, the starting port 2 switch 37a in the normal variable winning device 37, the gate switch 34a, the general winning port switches 35a to 35n, the count The switch 38a is a non-contact type magnetic proximity sensor (hereinafter referred to as a proximity switch) that includes a magnetic detection coil and detects a game ball using a phenomenon in which a magnetic field changes when a metal approaches the coil. Has been. A micro switch having a mechanical contact is used for the front frame opening detection switch 63 provided on the glass frame 15 or the like of the gaming machine 10 or the game frame opening detection switch 64 provided on the front frame (game frame) 12 or the like. be able to.

FIG. 3 is a block diagram of the control system of the pachinko gaming machine 10 according to the present embodiment.
The gaming machine 10 includes a game control device 100. The game control device 100 is a main control device (main board) for comprehensively controlling games, and a gaming microcomputer (hereinafter referred to as a gaming microcomputer) 111 is provided. The CPU unit 110 includes an input unit 120 having an input port, an output unit 130 having an output port, a driver, and the like, and a data bus 140 connecting the CPU unit 110, the input unit 120, and the output unit 130.

  The CPU section 110 receives signals (starting winning detection signals) from a gaming microcomputer (CPU) 111 called an amusement chip (IC) and a proximity switch interface chip (proximity I / F) 121 in the input section 120. An inversion circuit 112 composed of an inverter or the like that is logically inverted and input to the gaming microcomputer 111 and an oscillator such as a crystal oscillator are provided to generate a clock for a CPU operation clock, a timer interrupt, and a random number generation circuit. An oscillation circuit (crystal oscillator) 113 is included. The game control device 100 and electronic components such as a solenoid and a motor driven by the game control device 100 are supplied with a predetermined level of DC voltage such as DC32V, DC12V, and DC5V generated by the power supply device 400 so as to be operable. Is done.

  The power supply apparatus 400 includes a normal power supply including an AC-DC converter that generates the DC 32V DC voltage from a 24V AC power source, a DC-DC converter that generates a lower level DC voltage such as DC 12V and DC 5V from the DC 32V voltage, and the like. Unit 410, backup power supply unit 420 for supplying power supply voltage to the internal RAM of gaming microcomputer 111 in the event of a power failure, and a power failure monitoring circuit and an initialization switch to inform gaming control device 100 of the occurrence and recovery of power failure A control signal generation unit 430 that generates and outputs control signals such as a power failure monitoring signal, an initialization switch signal, and a reset signal is provided.

  In this embodiment, the power supply device 400 is configured separately from the game control device 100, but the backup power supply unit 420 and the control signal generation unit 430 are integrated on a separate board or the game control device 100, that is, the main control device 100. You may comprise so that it may provide on a board | substrate. Since the game board 30 and the game control device 100 are to be replaced when the model is changed, the backup power supply unit 420 and the control signal generation unit 430 are provided on a board different from the power supply apparatus 400 or the main board as in the embodiment. By providing, it can remove from the object of replacement | exchange and can aim at cost reduction.

  The backup power supply unit 420 can be composed of one large-capacity capacitor such as an electrolytic capacitor. The backup power is supplied to the game microcomputer 111 (particularly, the built-in RAM) of the game control device 100, and the data stored in the RAM is held even during a power failure or after the power is shut off. The control signal generation unit 430 monitors the voltage of 32V generated by the normal power supply unit 410, for example, detects the occurrence of a power failure when the voltage drops below 17V, for example, changes the power failure monitoring signal, and resets the signal after a predetermined time. Is output. In addition, a reset signal is output after a predetermined time has elapsed from the time when the power is turned on or the power is restored.

  The initialization switch signal is a signal generated when the initialization switch is turned on, and forcibly initializes information stored in the RAM 111C in the gaming microcomputer 111 and the RAM in the payout control device 200. . Although not particularly limited, the initialization switch signal is read when the power is turned on, and the power failure monitoring signal is repeatedly read in the main loop of the main program executed by the gaming microcomputer 111. The reset signal is a kind of forced interrupt signal and resets the entire control system.

  The gaming microcomputer 111 constitutes a control means for comprehensively controlling the game. Specifically, the gaming microcomputer 111 includes a CPU (central processing unit: microprocessor) 111A, a read-only ROM (read-only memory) 111B, and a RAM (random access memory) 111C that can be read and written as needed.

  The ROM 111B stores invariant information (programs, fixed data, various random number judgment values, etc.) for game control in a nonvolatile manner, and the RAM 111C stores a work area for the CPU 111A and various signals and random number values during game control. Used as As the ROM 111B or the RAM 111C, an electrically rewritable nonvolatile memory such as an EEPROM may be used.

In addition, the ROM 111B stores a variation pattern table for determining a variation pattern that defines, for example, the execution time of the special figure variation display game, the production contents, and the presence or absence of the reach state.
The variation pattern table is a table for the CPU 111A to determine the variation pattern by referring to the variation pattern random numbers 1 to 3 stored as the start memory. Further, the fluctuation pattern table includes a loss fluctuation pattern table selected when the result is lost, a big hit fluctuation pattern table selected when the result is per 15R or 2R, and the like. Further, these pattern tables include a second half variation pattern table and a first half variation pattern table.

  Reach (reach state) has a display device whose display state can change, and the display device derives and displays a plurality of display results at different times, and the plurality of display results are predetermined. In the gaming machine 10 in which the gaming state becomes a gaming state advantageous to the player (special gaming state) when the special result mode is entered, the game is already derived at the stage where some of the plurality of display results are not yet derived and displayed. This means a display state in which the displayed display result satisfies the condition for the special result mode. In other words, the reach state is deviated from the display condition that is the special result mode even when the display device's variable display control progresses and reaches the stage before the display result is derived and displayed. There is no display mode. For example, a state where so-called full-rotation reach is performed in a variable display region while maintaining a state in which special result modes are aligned (so-called full rotation reach) is also included in the reach state. The reach state is a display state at the time when the display control of the display device has progressed to reach a stage before the display result is derived and displayed, and is determined before the display result is derived and displayed. The display state in the case where at least a part of the display results of the plurality of variable display areas satisfies the condition for the special result mode.

  Thus, for example, a decorative special figure fluctuation display game displayed on a display device corresponding to a special figure fluctuation display game fluctuates a plurality of identification information for a predetermined time in each of the left, middle, and right fluctuation display areas on the display device. After displaying, when the display of the result mode is stopped in the order of left, right, and middle, the condition that becomes the special result mode is satisfied in the left and right variable display areas (for example, The state in which the variable display is stopped with the same identification information) is the reach state. In addition to this, when the variable display of all the variable display areas is temporarily stopped, the condition that the special result mode is satisfied in any two of the left, middle, and right variable display areas (for example, the same The state in which the identification information is obtained (except for the special result mode) may be set as the reach state, and the remaining one variable display area may be variably displayed from the reach state.

And this reach state includes a plurality of reach productions, and the possibility of deriving a special result mode is different (reliability is different). Premier reach etc. are set. The reliability increases in the order of no reach <normal reach <special 1 reach <special 2 reach <special 3 reach <premier reach. In addition, this reach state is included in a variable display mode at least in a case where a special result mode is derived in a special figure variable display game (when a big hit is achieved). That is, when it is determined that the special result mode is not derived in the special figure variable display game (when it is out of date), it may be included in the variable display mode. Therefore, the state in which the reach state has occurred is a state that is more likely to be a big hit than the case in which the reach state does not occur.
Here, the CPU 111A serves as reach state generation means capable of generating a reach state in the special figure variation display game based on the start memory stored in the RAM 111C as start storage means.

The CPU 111A executes a game control program in the ROM 111B, generates control signals (commands) for the payout control device 200 and the effect control device 300, and generates and outputs drive signals for the solenoid and the display device, thereby playing the gaming machine. 10 overall control is performed.
Although not shown, the game microcomputer 111 is a jackpot determining random number for the special figure variation display game, a big hit symbol random number for determining the big hit symbol, a variation pattern in the special figure variation display game (various reach and reach). A random number generation circuit for generating a variation pattern random number for determining a variation display game in a variation display without a game), a random number for determining a hit of a normal variation display game, and the like from the oscillation circuit 113 Based on the oscillation signal (original clock signal), a clock generator is provided that generates a timer interrupt signal for a predetermined period (for example, 4 milliseconds) for the CPU 111A and a clock that gives the update timing of the random number generation circuit.

  In addition, the CPU 111A selects one of a plurality of variation pattern tables stored in the ROM 111B in a start port switch monitoring process (step A1) or a special figure routine process (step A9) in a special figure game process to be described later. One fluctuation pattern table is acquired. Specifically, the CPU 111A determines the game result (big hit or miss) of the special figure fluctuation display game, the probability state (normal probability state or high probability state) of the special figure fluctuation display game as the current game state, and the current game. Based on the operation state (normal operation state or short-time operation state) of the normal variation winning device 37 as a state, the number of start memories, etc., one of the variation pattern tables is selected and acquired. To do.

  Although not shown, the payout control device 200 includes a CPU, a ROM, a RAM, an input interface, an output interface, and the like, and drives a payout motor of the payout unit in accordance with a prize ball payout command (command or data) from the game control device 100. , Control for paying out a prize ball. In addition, the payout control device 200 drives the payout motor of the payout unit based on the ball rental request signal from the card unit, and performs control for paying out the ball.

  The input unit 120 of the gaming microcomputer 111 includes a start port 1 switch 36a in the start winning port 36, a start port 2 switch 37a in the normal variation winning device 37, a gate switch 34a in the usual start gate 34, and a general winning port. An interface which is connected to the switches 35a to 35n and the count switch 38a and receives a negative logic signal such as a high level of 11V and a low level of 7V supplied from these switches, and converts it into a positive logic signal of 0V-5V. A chip (proximity I / F) 121 is provided. Proximity I / F 121 seems to be floating because the input range is 7V-11V, the lead wire of the proximity switch is improperly shorted, the switch is disconnected from the connector, or the lead wire is disconnected. An abnormal state can be detected, and an abnormality detection signal is output.

  All the outputs of the proximity I / F 121 are supplied to the second input port 122 and read into the gaming microcomputer 111 via the data bus 140, and also supplied from the main board 100 to the test firing test apparatus (not shown) via the relay board 70. It is like that. In addition, detection signals of the start port 1 switch 36a and the start port 2 switch 37a among the outputs of the proximity I / F 121 are input to the gaming microcomputer 111 via the inverting circuit 112 in addition to the second input port 122. It is configured. The inversion circuit 112 is provided because the signal input terminal of the gaming microcomputer 111 detects that a signal from a micro switch or the like is input, and detects negative logic, that is, low level (0 V) as an effective level. Because it is designed to do.

  Therefore, when a micro switch is used as the start port 1 switch 36a and the start port 2 switch 37a, the detection signal can be directly input to the gaming microcomputer 111 without providing the inverting circuit 112. That is, when it is desired to directly input negative logic signals from the start port 1 switch 36a and the start port 2 switch 37a to the gaming microcomputer 111, the proximity switch cannot be used. As described above, the proximity I / F 121 has a signal level conversion function. In order to enable such a level conversion function, the proximity I / F 121 is supplied with a voltage of 12 V from the power supply device 400 in addition to a voltage such as 5 V required for normal IC operation. It has become.

  Further, the input unit 120 includes a start winning opening 36 converted by signals from the fraud detection magnetic sensor switch 61 and the vibration sensor switch 62 provided on the front frame 12 of the gaming machine 10 and the proximity I / F 121. The start port 1 switch 36a in the inside, the start port 2 switch 37a in the normal variation winning device 37, the gate switch 34a, the general winning port switches 35a to 35n, and the signals from the count switch 38a are taken in via the data bus 140. A second input port 122 for supplying to the microcomputer 111 is provided. The data held in the second input port 122 is read out by asserting the enable signal CE1 (changing to an effective level) by the gaming microcomputer 111 decoding the address assigned to the second input port 122. be able to. The same applies to other ports described later.

  Further, the input unit 120 receives signals and payouts from the front frame opening detection switch 63 provided on the glass frame 15 and the like of the gaming machine 10 and the game frame opening detection switch 64 provided on the front frame (game frame) 12 and the like. A status signal indicating a payout abnormality from the control device 200, a shot ball break switch signal indicating a shortage of game balls before payout, and an overflow switch signal indicating overflow are fetched and supplied to the game microcomputer 111 via the data bus 140. One input port 123 is provided. The overflow switch signal is a signal that is output when it is detected that a predetermined amount or more of game balls are stored in the lower plate 23 (full).

  Further, the input unit 120 is provided with a Schmitt trigger circuit 124 for inputting signals such as a power failure monitoring signal, an initialization switch signal, and a reset signal from the power supply device 400 to the gaming microcomputer 111 and the like. The circuit 124 has a function of removing noise from these input signals. Of the signals from the power supply device 400, the power failure monitoring signal and the initialization switch signal are once inputted to the first input port 123 and taken into the gaming microcomputer 111 via the data bus 140. That is, it is treated as a signal equivalent to the signal from the various switches described above. This is because the number of terminals receiving external signals provided in the gaming microcomputer 111 is limited.

  On the other hand, the reset signal RST from which noise has been removed by the Schmitt trigger circuit 124 is directly input to a reset terminal provided in the gaming microcomputer 111 and is supplied to each port of the output unit 130. Further, the reset signal RST is directly output to the relay board 70 without going through the output unit 130, thereby turning off the test test signal held in the port (not shown) of the relay board 70 for output to the test board. It is configured as follows. Further, the reset signal RST may be configured to be output to the test firing test apparatus via the relay board 70. The reset signal RST is not supplied to the ports 122 and 123 of the input unit 120. Data set to each port of the output unit 130 by the gaming microcomputer 111 immediately before the reset signal RST is input needs to be reset to prevent malfunction of the system, but each data of the input unit 120 is input immediately before the reset signal RST is input. This is because the data read by the gaming microcomputer 111 from the port is discarded when the gaming microcomputer 111 is reset.

  The output unit 130 is connected to the data bus 140 and outputs a 4-bit data signal output to the payout control device 200, a control signal (data strobe signal) indicating the validity / invalidity of the data, and a data strobe signal SSTB output to the effect control device 300. 1 and a second output port 132 for generating an 8-bit data signal to be output to the effect control device 300. Data is transmitted from the game control device 100 to the payout control device 200 and the effect control device 300 by parallel communication. In addition, the data strobe signal from the first output port 131 is input to the output unit 130 in order to prevent a signal from being input to the game control device 100 from the side of the effect control device 300, that is, to ensure one-way communication. A unidirectional buffer 133 that outputs an 8-bit data signal from the SSTB and the second output port 132 is provided. A buffer may be provided for a signal output from the first output port 131 to the payout control device 200.

  In addition, the output unit 130 is connected to the data bus 140 via a relay board 70 for data indicating special symbol information of the variable display game to a test firing test apparatus of an accredited organization (not shown) and a signal indicating the probability status of jackpot. The output buffer 134 is configured to be mountable. This buffer 134 is a component that is not mounted on a game control device (main board) of a pachinko gaming machine as an actual machine (mass production product) installed in the game store. A detection signal output from the proximity I / F 121, such as a start port switch, that is not required to be processed is supplied to the test firing test apparatus via the relay board 70 without passing through the buffer 134.

  On the other hand, detection signals such as the magnetic sensor switch 61 and the vibration sensor switch 62 that cannot be supplied to the test fire testing device as they are are once taken into the gaming microcomputer 111 and processed into other signals or information.

Thereby, the cooperation of the operations of the video control microcomputer 312 and the VDP 313 can be improved.

Next, game control performed in these control circuits will be described.
The CPU 111A of the game microcomputer 111 of the game control device 100 extracts a random number for determining the hit of the usual figure based on the input of the detection signal of the game ball from the gate switch 34a provided in the usual figure start gate 34, and the ROM 111B. Is compared with the determination value stored in, and a process for determining whether or not the normal-game fluctuation display game is hit is performed. Then, after the identification symbol is variably displayed for a predetermined time on the general symbol display 53, a processing for displaying a general symbol variation display game to be stopped is performed. When the result of the normal map variation display game is a win, a special result mode is displayed on the general map display 53, the general electric solenoid 37c is operated, and the opening / closing members 37b and 37b of the normal variable prize winning device 37 are set in advance. Time (for example, 0.3 seconds) is controlled to be released as described above.
In addition, when the result of the normal map change display game is out of order, control is performed on the general map display 53 to display the result form of the shift.

Further, a start winning (starting memory) is stored based on an input of a detection signal of a game ball from a starting port 1 switch 36a provided in the starting winning port 36, and based on this start memory, the first special figure variation display game is stored. The random number value for jackpot determination is extracted and compared with the determination value stored in the ROM 111B, and a process of determining whether or not the first special figure variation display game is missed is performed.
In addition, the start memory is stored based on the input of the detection signal of the game ball from the start port 2 switch 37a provided in the normal variation winning device 37, and based on this start memory, for the big hit determination of the second special figure variable display game A random number value is extracted and compared with the determination value stored in the ROM 111B, and a process of determining whether or not the second special figure variation display game is hit is performed.

  Then, the CPU 111 </ b> A of the game control device 100 outputs a control signal (effect control command) including the determination results of the first special figure variation display game and the second special figure variation display game to the effect control device 300. Then, after the identification symbol is variably displayed for a predetermined time on the special figure 1 display 51 or the special figure 2 display 52, a process for displaying a special figure fluctuation display game to be stopped is performed.

In addition, in the production control device 300, based on the control signal from the game control device 100, the display device 41 performs a process of displaying a decoration special figure fluctuation display game corresponding to the special figure fluctuation display game.
Furthermore, in the production control device 300, based on the control signal from the game control device 100, the sound output from the speakers 19a and 19b, the process of controlling the light emission of various LEDs, and the like are performed.

Then, the CPU 111A of the game control device 100 displays the special result mode on the special figure 1 display 51 and the special figure 2 display 52 and generates a special game state when the result of the special figure variation display game is successful. To perform the process.
In the process of generating the special game state, the CPU 111A performs control for allowing the game ball to flow into the special winning opening by, for example, opening the open / close door 38c of the special variable winning apparatus 38 by the special winning opening solenoid 38b. .

Then, a condition that either a predetermined number (for example, 10) of game balls wins the grand prize opening or a predetermined time (for example, 25 seconds or 1 second) elapses from the opening of the big prize opening is achieved. Opening the grand prize opening until one is made is defined as one round, and control (cycle game) is performed to continue (repeat) this for a predetermined number of rounds (for example, 15 times or 2 times).
Further, when the result of the special figure variation display game is out of order, the special figure 1 display 51 and the special figure 2 display 52 are controlled to display the result form of the deviation.

In addition, the game control device 100 can generate a probability change state as a game state after the special game state ends based on the result mode of the special figure variation display game.
This probability variation state is a state (high probability state) in which the probability of a hit result in the special figure variation display game is higher than the normal probability state. In addition, the first special figure variation display game and the second special figure variation display game, regardless of which one of the first special figure variation display game and the second special figure variation display game results in a certain variation state. Both display games are in a probable state.

In addition, the game control device 100 can generate a short time state as a gaming state after the special gaming state ends based on the result mode of the special figure variation display game.
In this time-short state, control is performed so that the normal-variation display game and the normal variation winning device 37 are in the time-short operation state. Specifically, in the short-time state, the execution time of the above-described usual-variable display game is controlled to be a second variable display time shorter than the first variable display time (for example, 10 seconds is 1 second). Thus, the number of times of opening of the normal variation winning device 37 per unit time is controlled to be substantially increased. Further, in the short time state, when the normal variation winning device 37 is released as a result of the normal variation display game being won, the release time becomes a second release time longer than the first release time in the normal state. (For example, 0.3 seconds is 1.7 seconds). In the short-time state, the number of times of opening of the normal variation winning device 37 is not the first opening number of one time but a plurality of times of two or more times (for example, (3 times) the second number of times of opening.

It should be noted that the execution time of the normal variation display game is set to the second variation display time (for example, 1 second), and the release mode of the normal variation winning device 37 is the second release time (for example, 1.7). Second), and the number of times of opening with respect to one hit result of the normal variation display game is the second number of times of opening (for example, 3 times), either one or both may be performed. May be. In the short-time operation state, control may be performed so that the probability of a hit result of the normal-variable display game is higher than that in the normal operation state.
Thereby, it becomes easy to win a game ball in the normal variation winning device 37, and the second special figure variation display game can be easily started.

  Note that the time variation operation state of the probability variation state, the normal variation display game, and the normal variation winning device 37 can be generated independently, and both can be generated simultaneously, or only one of them can be generated. Is possible.

Next, the control executed by the game microcomputer (game microcomputer) 111 of the game control apparatus 100 will be described.
The control process by the gaming microcomputer 111 is a main process (mainly see FIGS. 6 and 7) that is a main routine that is repeated as a loop process, and a timer that is performed at a predetermined time period (for example, 4 ms) as an interrupt routine for the main process. Interrupt processing (see FIG. 9).

[Main processing]
First, the main process will be described.
The main process is started when the power is turned on. In this main process, as shown in FIG. 6, first, an interrupt prohibition process (step S1) is performed, and then an interrupt vector setting process (step S1) for setting a jump destination vector address to be executed when an interrupt occurs. S2), a stack pointer setting process (step S3) for setting a stack pointer that is the start address of an area in which a value of a register or the like is saved when an interrupt occurs, and an interrupt mode setting process (step S4) for setting an interrupt processing mode. )I do.

  Next, in order to wait for the program of the payout control apparatus (payout board) 200 to start up normally, for example, a time of 4 ms is waited (step S5). As a result, when the power is turned on, the game control device 100 first rises and the command is sent to the payout control device 200 before the payout control device 200 starts up, so that the payout control device 200 avoids losing the command. be able to. Thereafter, access to a readable / writable RWM (read / write memory) such as a RAM or EEPROM is permitted, and all output ports are set to off (no output) (steps S6 and S7). Also, the serial port ((port previously installed in the gaming microcomputer 111) is not used in this embodiment because it is in parallel communication with the payout control device 200 and the effect control device 300). Is performed (step S8).

Subsequently, it is determined whether or not the initialization switch in the power supply device 400 is turned on (step S9). Here, if it is determined that the initialization switch is off (step S9; No), in step S10, after checking the data of the power failure inspection area in the RWM, it is determined whether or not the power failure is restored (step S11). If it is determined in step S11 that the power failure has been restored (step S11; Yes), the process proceeds to step S12, and a process of calculating data called a checksum and whether the calculated checksum is normal or abnormal are determined (step S13).
If it is determined in step S9 that the initialization switch is on (step S9; Yes), if it is determined in step S11 that the power failure is not restored (step S11; No), and if the checksum is not normal in step S13 (step If it is determined as S13; No), the process jumps to step S20 in FIG.

  If it is determined in step S13 that the checksum is normal (step S13; Yes), the process proceeds to step S14 in FIG. 7, and a power failure occurs in the area to be initialized in the RWM (read / write memory: RAM in the embodiment). After the initial value at the time of recovery is saved (stored), the area related to error and fraud monitoring is reset (step S15). Next, an area for storing the gaming state in the RWM is examined to determine whether or not the gaming state is a high probability state (step S16). If it is determined that the probability is not high (step S16; No), steps S17 and S18 are skipped and the process proceeds to step S19.

  If it is determined in step S16 that the probability is high (step S16; Yes), a high-probability notification LED (error The display 58) is set to ON (lighted) (step S18), and the process proceeds to step S19. In step S19, a process for transmitting a power restoration command corresponding to a process number prepared for reasonably executing a special figure game process described later to the effect control device 300 is performed, and the process proceeds to step S23.

  On the other hand, when jumping from step S9, S11, S13 to step S20, the work area in the RAM used by the CPU is first reset, and then the initial value at power-on is saved in the area to be initialized (step S21). Then, in step S22, a process of transmitting a power-on command to the effect control device 300 is performed, and the process proceeds to step S23. In step S23, a process of starting a CTC (Counter / Timer Circuit) circuit that generates a timer interrupt signal and a random number update trigger signal (CTC) in the gaming microcomputer 111 (clock generator) is performed.

  The CTC circuit is provided in a clock generator in the gaming microcomputer 111. The clock generator divides an oscillation signal (original clock signal) from the crystal oscillator 113, and a timer interrupt signal having a predetermined period (for example, 4 milliseconds) for the CPU 111A based on the divided signal. And a CTC circuit for generating a signal CTC that gives a trigger for updating a random number to be supplied to the random number generation circuit.

  After the CTC activation process in step S23, a process for activating and setting the random number generation circuit is performed (step S24). Specifically, a code (specified value) for starting the random number generation circuit is set in a predetermined register (CTC update permission register) in the random number generation circuit, and a maximum value (including an update mode) in the maximum value setting register The CPU 111 </ b> A performs the above setting, tap setting to the tap setting register, and the like. Then, in step S25, the values of predetermined registers (soft random number registers 1 to n) in the random number generation circuit at the time of power-on are changed to corresponding initial value random numbers (random numbers for determining the big hit symbol (big hit symbol random number 1, big hit) The design random number 2) is saved in a predetermined area of the RWM as an initial value (start value) of a random number (per random number) for determining the hit of a normal figure, and then an interrupt is permitted (step S26). In the random number generation circuit in the CPU 111A used in the present embodiment, since the initial value of the soft random number register is changed every time the power is turned on, this value is the initial value of various initial value random numbers generated on the CPU side. By setting (start value), it is possible to break the regularity of random numbers generated by software, making it difficult for a player to obtain illegal random numbers.

  Subsequently, initial value random number update processing (step S27) is performed to update the values of various initial value random numbers to break the regularity of the random numbers. In the present embodiment, although not particularly limited, the big hit random number is configured to be generated using a random number (big hit random number) generated in a random number generation circuit. That is, the big hit random number is a hard random number generated by hardware, and the big hit symbol random number, the hit random number, and the variation pattern random number are soft random numbers generated by software.

  After the initial value random number update process in step S27, the power failure monitoring signal input from the power supply device 400 is read through the port and data bus and checked to determine whether or not a power failure has occurred (step S28). If no power failure has occurred (step S28; No), the process returns to step S27, and the initial value random number update processing and the power failure monitoring signal check (loop processing) are repeated. By permitting an interrupt before the initial value random number update process (step S27) (step S26), when a timer interrupt occurs during the initial value random number update process, the interrupt process is preferentially executed. Can be prevented from being interrupted by waiting for the initial value random number update process.

  Note that the initial value random number update process in step S27 includes a method of performing the initial value random number update process in the timer interrupt process in addition to the main process. In order to avoid execution of value random number update processing, when performing initial value random number update processing in the main processing, it is necessary to disable interrupt and then update to cancel the interrupt. In the timer interrupt process, the initial value random number update process is not performed. If it is only in the main process, there is no problem even if the interrupt is canceled before the initial value random number update process, thereby simplifying the main process. There is an advantage that

  If it is determined in step S28 that a power failure has occurred (step S28; Yes), processing for temporarily prohibiting interruption (step S29) and processing for turning off all output ports (step S30) are performed. After that, after the process of saving the power failure recovery inspection area check data in the power interruption recovery inspection area (step S31) and the process of calculating the checksum when the RWM is turned off (step S32), access to the RWM is prohibited. After performing the process (step S33), it waits for the power supply of the gaming machine to be cut off. In this way, the check data is saved in the power failure recovery inspection area and the checksum at the time of power shutdown is calculated, so that whether or not the information stored in the RWM before the power shutdown is correctly backed up can be checked. This can be determined when the power is turned on again.

[Initial value random number update processing]
Next, details of the initial value random number update process (step S27) in the main process described above will be described.
As shown in FIG. 8, in the initial value random number update process, the big hit symbol initial value random number 1 is incremented (updated (+1)) (step S271), and the hit initial value random number is incremented (updated (+1)) ( Step S272), processing to increment (update (+1)) the jackpot symbol initial value random number 2 (Step S273), tap setting register (608b2) in a random number generation circuit (608) described later built in the gaming microcomputer 111 The process (step S274) of incrementing (updating (+1)) the tap counter that generates the value to be set is sequentially performed. The tap counter is in the RAM 111C of the gaming microcomputer 111. In each random number update process, an upper limit value is provided. When the upper limit value is reached, the upper limit value is 0, and a process of sequentially updating (+1) between 0 and the upper limit value is performed.

  Here, the “big hit symbol initial value random number 1” is a random number that is the initial value of the random number that determines the big hit symbol stop symbol of the special figure 1, and the “big hit symbol initial value random number 2” is the big hit symbol stop value of the special figure 2 This is the initial random number of the random number to be used. The “hit initial value random number” is a random number that is an initial value of a random number that determines the hit of the usual game. In this way, the randomness of the random number can be increased by continuing to increment the random number as long as time permits in the main process. As will be described in detail later, the random number generation circuit (608) has a random number generation function called an M-sequence random number in addition to the counter-type random number generation function, and the set value of the tap setting register (608b2) is M Used as an index to specify the formula for generating the sequence random number. Accordingly, the randomness of the M-sequence random number generated by the M-sequence random number generation function can be improved by repeatedly incrementing the tap counter in step S274.

[Timer interrupt processing]
Next, timer interrupt processing will be described.
As shown in FIG. 9, the timer interrupt process is started when a periodic timer interrupt signal generated by the CTC circuit in the clock generator is input to the CPU 111A. When a timer interrupt occurs in the gaming microcomputer 111A, the timer interrupt process of FIG. 9 is started.

  When the timer interrupt process is started, a register saving process (step S41) is performed in which a value held in a predetermined register is transferred to the RWM. In the Z80 microcomputer used as the gaming microcomputer in this embodiment, the processing can be replaced by saving the value held in the front register to the back register. Next, an input process (step S42) for taking in inputs from various sensors (start port 1 switch 36a, start port 2 switch 37a, gate switch 34a, count switch 38a, etc.), that is, reading the state of each input port. )I do. Then, based on the output data set in various processes, an output process (step S43) for performing drive control of an actuator such as a solenoid (large winning opening SOL38b, general electric power SOL37c) is performed.

  Next, a command transmission process (step S44), a random number update process 1 (step S45), and a random number update process 2 (steps) for outputting commands set in the transmission buffer in various processes to the effect control device 300, the payout control device 200, and the like. S46) is performed. Thereafter, it is monitored whether a normal signal is input from the start port 1 switch 36a, the start port 2 switch 37a, the usual gate switch 34a, the winning port switch 35a... 35n, and the count switch 38a. A prize opening switch / error monitoring process (step S47) is performed to determine whether the front frame and the glass frame are open. Also, a special figure game process (step S48) for performing a process related to the special figure variation display game and a general figure game process (step S49) for performing a process related to the common figure variation display game are performed.

  Next, a segment LED editing process (step S50) that is provided in the gaming machine 10 and drives a segment LED that displays special information variation game and various information related to the game to display desired contents, and a magnetic sensor switch 61. And the magnet fraud monitoring process (step S51) which checks the detection signal from the vibration sensor switch 62 and determines whether there is any abnormality is performed. Then, external information editing processing (step S52) for setting a signal to be output to various external devices in the output buffer is performed. Subsequently, a process of clearing the interrupt request and declaring the end of the interrupt (step S53), a process of restoring the register data saved in step S41 (step S54), and a process of permitting an interrupt (step S54) Step S55) is performed, and the timer interrupt process is terminated.

[Input processing]
Next, details of the input process (step S42) in the timer interrupt process described above will be described.
As shown in FIG. 10, in the input process, first, the state of the switch detection signal taken into the input port 1, that is, the first input port 123 is read (step S421). If there is an unused bit in the 8-bit port, the bit state is cleared (step S422).
Subsequently, the read state of the input port 1 is saved (stored) in the switch control area 1 in the RWM (step S423). Thereafter, in step S424, a parameter for reading the state of the signal taken into the input port 2, that is, the second input port 122 is prepared, and then the process proceeds to the switch reading process (step S425). In this embodiment, “preparation” means setting a value in a register, but is not limited to this, and a value may be set in an RWM or other memory.

[Switch read processing]
Next, details of the switch reading process (step S425) in the above-described input process will be described.
As shown in FIG. 11, in the switch reading process, first, the state of the signal taken into the input port designated by the parameter prepared in step S424, that is, the second input port 122 is read (step S251). If there is an unused bit in the 8-bit port, the bit state is cleared (step S252). Subsequently, the read state of the input port 2 is saved (stored) in the switch control area 2 in the RWM (step S253). Then, it waits for the delay time (0.1 ms) until the second reading to elapse (step S254).

  When the delay time (0.1 ms) elapses, a second reading of the state of the signal taken into the second input port 122 is performed (step S255). If there is an unused bit in the 8-bit port, the bit state is cleared (step S256). Subsequently, the read state of the input port 2 is saved (stored) in the switch control area 2 (step S257). Then, a bit, that is, a signal changed by the first reading and the second reading is detected (step S258).

  Thereafter, a bit that can be determined by the current two readings, that is, the processing of steps S251 to S258 is extracted (step S259). On the other hand, for bits that cannot be determined by two readings, the values read in the switch reading process at the previous interruption are extracted (step S260). Thereby, it is possible to obtain a signal state from which noise due to chattering of the switch and the like is removed. Next, the values extracted in steps S259 and S260 are combined and saved in the RWM as the final state of the reading process (step S261). Thereafter, a bit whose definite state has changed to a high level is detected, saved in the RWM as detection of the rising edge of the corresponding signal, and the switch reading process is terminated (step S262).

  When the timer interrupt cycle is short (for example, 2 ms), the switch reading is performed once for each interrupt processing, and the signal changes by comparing the result with the previous reading. There is a method for determining whether or not the switch has been made. However, if the switch state read by the previous interrupt is lost before the next interrupt processing, the correct determination may not be made. On the other hand, it is possible to avoid the above-described problems by performing the switch reading process twice in one interrupt process at a predetermined time difference as in the present embodiment.

[Output processing]
Next, details of the output process (step S43) in the above-described timer interrupt process will be described.
As shown in FIG. 12, in the output process, first, the port 136 (see FIG. 3) for outputting the segment data of the batch display device (LED) 50 is reset (step S431). Subsequently, the digit counter value for sequentially scanning the digit lines of the collective display device (LED) 50 is updated (step S432), and the output data of the LED digit line corresponding to the digit counter value is loaded (step S432). S433). Next, after the output data of the special winning opening solenoid 38b is loaded and combined with the digit output data, the output data of the ordinary solenoid 37c is loaded and further combined (steps S434 and S435). Then, the combined data is output to the solenoid / test terminal / digit data output port 135 (step S436).

  Thereafter, the segment line output data is obtained from the segment data area in the RWM corresponding to the value of the digit counter (step S437). Then, the acquired data is output to the segment output port 136 (step S438). Subsequently, the data to be output to the external information output terminal 71 is loaded and synthesized, and output to the external information output port 137 (steps S439 and S440). Next, the output data 1 to 3 of the test signal to be output to the test firing test apparatus are loaded and combined, and the combined data is output to the test terminal output port 1 provided on the relay board 70 (steps S441 and S442). ).

  Thereafter, the test signal output data 4 to 6 to be output to the test firing test apparatus are loaded and combined, and the combined data is output to the test terminal output port 2 provided on the relay board 70 (steps S443 and S444). ). Next, the test signal output data 7 to 8 to be output to the test firing test apparatus are loaded and combined, and the combined data is output to the test terminal output port 3 provided on the relay board 70 (steps S445 and S446). ). Further, the test signal output data 9 to 10 to be output to the test firing test apparatus are loaded and synthesized, and the synthesized data is outputted to the test terminal output port 4 provided on the relay board 70 (steps S447 and S448). . Furthermore, the output data 11 of the test signal output to the test firing test apparatus is loaded and synthesized, and the synthesized data is output to the test terminal output port 5 provided on the relay board 70 (steps S449 and S450). The output process in FIG. 12 is terminated.

[Command transmission processing]
Next, details of the command transmission process (step S44) in the above-described timer interrupt process will be described.
As shown in FIG. 13, the command transmission process includes an effect control command transmission process (step S410) for the effect control device 300 and a payout command transmission process (step S420) for the payout control device 200.

[Direction control command transmission processing]
First, details of the effect control command transmission process (step S410) in the command transmission process described above will be described.
As shown in FIG. 14, in the effect control command transmission process, first, the value of the light counter that is “+1” when the transmission command is set to RWM, and “+1” when the transmission command is read from the RWM. The read counter value is compared to check whether a command is set (step S411). Specifically, if the value of the write counter and the value of the read counter are the same, it is determined that there is no setting command. If the value of the write counter does not match the value of the read counter, an unsent command Is set (step S412).

  If it is determined in step S412 that there is no setting command (step S412; No), the effect control command transmission process is skipped, and a command is set in step S412 (step S412; Yes). If it is determined, the read counter is updated (+1) in the next step S413. Then, the command is loaded from the command transmission area (MODE (upper byte)) corresponding to the value of the read counter (step S414). Then, the area containing the acquired command is reset (step S415). Further, a command is loaded from the command transmission area (ACTION (lower byte)) corresponding to the value of the read counter (step S416). Then, the area containing the acquired command is reset (step S416). Thereafter, the process proceeds to an effect control command output process (step S418).

[Direction control command output processing]
Next, details of the effect control command output process (step S418) in the effect control command transmission process described above will be described.
As shown in FIG. 15A, in the effect control command output process, first, an off time of the strobe signal indicating that the command (MODE) is being output is prepared (step S181), and the command data output process (step S182). Execute. Thereafter, a command (ACTION) is output (step S183), and a strobe signal OFF time indicating that the command (ACTION) is being output is prepared (step S184), and then command data output processing (step S185) is executed.

[Command data output processing]
Next, details of the command data output process (steps S182 and S185) in the above-described effect control command output process will be described.
As shown in FIG. 15B, in the command data output process, first, in order to prevent the state immediately before the port from being lost, the port state holding data of the output port 131 including the strobe signal of the effect control command output. Is loaded (step S821). Then, the production control command is output to the output port 132 (step S822), and the strobe signal in the off state (for example, low level indicating data reading invalidity) is held in the output port 131 with the signal excluding the strobe signal held in the previous state. Is added and output (step S823). Then, in the next step S824, it is determined whether or not the time for turning off the strobe signal (off time) has ended. If it is determined that the off time has not ended (step S824; No), the process returns to step S822 and the above process is repeated.

  On the other hand, if it is determined in step S824 that the off time has expired (step S824; Yes), the process proceeds to step S825, and the time for the strobe signal to be in an on state (for example, a high level indicating that data reading is valid) is set. Subsequently, the strobe signal is set to the on state while the signals excluding the strobe signal of the output port 131 are held in the immediately previous state on the register holding the data loaded in step S821 (step S826). Then, an effect control command is output (step S827), and an on-state (high level) strobe signal is output (step S828).

  Then, in the next step S829, it is determined whether or not the time during which the strobe signal should be turned on (on time) has ended. If it is determined that the on-time has not ended (step S829; No), the process returns to step S827 and the above process is repeated. If it is determined in step S829 that the on-time has ended (step S829; Yes), the process proceeds to step S830, the off-state strobe signal is set, and the off-state strobe signal is output (step S831). Then, the command data output process ends. The reason why the effect control command is output again in step S827 is to prevent the effect control command being output from being output after the power failure is restored when a power failure occurs during the loop processing in steps S827 to S829. is there. It is also possible to avoid changing the command code due to noise. In addition, it is also possible to loop only each process in this step S824 and step S829.

[Payout command transmission processing]
First, details of the payout command transmission process (step S420) in the command transmission process described above will be described.
As shown in FIG. 16, in the payout command transmission processing, first, it is checked whether there is a count number other than “0” in the winning number counter area provided for each winning opening (step S201). Here, when it is determined that there is no count number (step S202: No), the process proceeds to step S203 to update the address of the winning number counter area to be checked and check the counting number of all the winning number counter areas. It is determined whether or not has been completed (step S204). If it is determined that all checks have been completed (step S204; Yes), the command transmission process ends. On the other hand, if it is determined in step S204 that all checks have not been completed (step S204; No), the process returns to step S201 and the above process is repeated.

  If it is determined in step S202 that there is a count number (step S202; Yes), the process proceeds to step S205, and the count number in the winning number counter area is subtracted (-1). Thereafter, a payout command (negative logic data) corresponding to the winning number counter area, that is, the winning opening is acquired (step S206). Then, an off time of the strobe signal indicating whether data reading is valid or invalid (for example, a time during which the data reading is maintained at a low level) is set (step S207). In the next step S208, the payout command (negative logic data) acquired in step S206 and the off-state (low level) strobe signal are output to the port 131 (see FIG. 3).

  Thereafter, it is determined whether or not the OFF time set in step S207 has elapsed (step S209). If it has not elapsed (step S209; No), the process returns to step S208, and if it has elapsed (step S209; Yes). Then, the process proceeds to step S210. In step S210, the strobe signal is set to an on state (high level), and then the remaining output time of negative logic data is set (step S211). In the next step S212, the payout command (negative logic data) is continuously output and the on-state (high level) strobe signal is output to the port 131. Thereafter, it is determined whether or not the remaining output time of the negative logic data set in step S211 has elapsed (step S213). If it has not elapsed (step S213; No), the process returns to step S212, and if it has elapsed (step S213). In step S213; Yes, the process proceeds to step S214.

  In step S214, the negative logic payout command data is inverted to generate positive logic payout command data. Then, the remaining on-time (high level time) of the strobe signal is set (step S215). In the next step S216, the payout command (positive logic data) generated in step S214 and the strobe signal in the on state (high level) are output to the port 131. Thereafter, it is determined whether or not the on-time set in step S215 has elapsed (step S217). If it has not elapsed (step S217; No), the process returns to step S216, and if it has elapsed (step S217; Yes). Then, the process proceeds to step S218.

  In step S218, the strobe signal is set to the off state (low level), and then the remaining output time of the positive logic data is set (step S219). In the next step S220, the payout command (positive logic data) is continuously output and the off-state (low level) strobe signal is output to the port 131. Thereafter, it is determined whether or not the remaining output time of the positive logic data set in step S219 has elapsed (step S221). If it has not elapsed (step S221; No), the process returns to step S220. In step S221; Yes, the process proceeds to step S222. In step S222, positive logic payout command data is saved in the RWM as port state holding data, and the command transmission process is terminated.

  As described above, by outputting negative logic payout command data and then outputting positive logic payout command data, the command receiving side reads and compares negative logic payout command data and positive logic payout command data. Thus, it can be determined whether or not a correct command has been received. For example, the negative logic payout command data received earlier is logically inverted and compared with the positive logic payout command data received later. It is possible to receive an accurate command by making a request to the game control device.

[Random number update process 1]
Next, details of the random number update process 1 (step S45) in the timer interrupt process described above will be described.
The random number update process 1 is a process for updating the initial value (start value) of the jackpot symbol random number 1, the hit random number, and the jackpot symbol random number 2 that are the targets of the initial value random number update process of FIG. The initial value set in the register (start value setting register 608b5) in the random number generation circuit (FIG. 48: 608) provided in the microcomputer 111 is updated.

  As shown in FIG. 17, in the random number update process 1, first, the value of the soft random number status register (608b15) indicating the update state of the random number is read (step S451). Then, it is checked whether there is a random number waiting for the next initial value (start value) setting after one round of the random number (step S452). Here, if there is no random number waiting for initial value setting, the random number update processing 1 is terminated (step S453: No). On the other hand, when there is a random number waiting for initial value setting, the process proceeds to step S454 (step S453: Yes). As described above, the gaming microcomputer 111 serving as the game control means, based on the value of the soft random number status register that stores the setting information indicating whether or not the circulation initial value (start value) has been set in the random number counter, Therefore, every time the random number counter makes a round, the next round initial value can be set reliably.

  In step S454, it is checked whether the usual hit random number is a random number waiting for the next initial value (start value) setting. Here, if it is not waiting for the initial value setting, the process jumps to step S457 (step S455: No). On the other hand, when the normal hit random number is waiting for the initial value setting, the process proceeds to step S456 (step S455: Yes). In step S456, the next initial value of the normal hit random number is set in the register holding the start value of the corresponding random number counter (random number area), and the process proceeds to step S457.

  In step S457, it is checked whether the jackpot symbol random number 1 is a random number waiting for the next initial value (start value) setting. Here, if not waiting for the initial value setting, the process jumps to step S460 (step S458: No). On the other hand, when the big hit symbol random number 1 is waiting for the initial value setting, the process proceeds to step S459 (step S458: Yes). In step S459, the next initial value of jackpot symbol random number 1 is set in the register holding the start value of the corresponding random number counter (random number region), and the flow proceeds to step S460.

  In step S460, it is checked whether the jackpot symbol random number 2 is a random number waiting for the next initial value (start value) setting. If the initial value setting is not awaited, the random number update process 1 ends (step S461: No). On the other hand, when the big hit symbol random number 2 is waiting for the initial value setting, the process proceeds to step S462 (step S461: Yes). In step S462, the next initial value of the jackpot symbol random number 2 is set in the register holding the start value of the corresponding random number counter (random number area), and the random number update processing 1 is terminated.

[Random number update process 2]
Next, details of the random number update process 2 (step S46) in the timer interrupt process described above will be described with reference to FIG.
The random number update process 2 is a process for updating the calculation formulas (characteristic polynomials) of the variation pattern random numbers 1, 2, and 3 for determining the variation pattern in the variation display game of the special figure 1 and the special figure 2, and the gaming microcomputer The tap value set in the register (tap setting register 608b2) in the random number generation circuit (FIG. 48: 608) included in 111 is updated. The fluctuation pattern random numbers 1, 2 and 3 are shared and used in the fluctuation display game of FIG. 1 and FIG. 2, and the second half fluctuation selection table is selected based on the fluctuation pattern random number 1 and the fluctuation pattern random number 2 is selected. The second half fluctuation pattern of the fluctuation display game of special figure 1 and special figure 2 is selected from the second half fluctuation selection table, and the second half fluctuation of the fluctuation display game of special figure 1 and special figure 2 is selected from the first half fluctuation selection table based on the fluctuation pattern random number 3. You will be asked to select a pattern.

  As shown in FIG. 18A, in the random number update process 2, the CPU 111A of the gaming microcomputer 111 first reads the value of the soft random number status register (FIG. 48: 608b15) indicating the update state of the random number (step S601). Then, it is checked whether there is a random number waiting for the next tap setting after one round of random numbers (step S602). Here, if there is no random number waiting for tap setting, the random number update processing 2 is terminated (step S603: No). On the other hand, when there is a random number waiting for tap setting, the process proceeds to step S604 (step S603: Yes). As described above, the gaming microcomputer 111 as the game control means determines the next tap value based on the value of the soft random number status register that stores setting information indicating whether the tap value is set in the tap setting register. Since it is set, the next tap value can be surely set every time the random number counter makes a round. Note that one round means a state in which a random number appears within a possible range of random numbers.

  In step S604, it is checked whether the fluctuation pattern random number 1 is a random number waiting for the next tap setting. If the variation pattern random number 1 is not waiting for the next tap setting, the process jumps to step S607 (step S605: No). On the other hand, when the fluctuation pattern random number 1 is waiting for the next tap setting (step S605: Yes), the process proceeds to step S606 and the tap setting process is executed.

  In step S607, it is checked whether the fluctuation pattern random number 2 is a random number waiting for the next tap setting. If the fluctuation pattern random number 2 is not waiting for the next tap setting, the process jumps to step S610 (step S608: No). On the other hand, when the variation pattern random number 2 is waiting for the next tap setting (step S608: Yes), the process proceeds to step S609 to execute the tap setting process.

  In step S610, it is checked whether the fluctuation pattern random number 3 is a random number waiting for the next tap setting. Here, if the variation pattern random number 3 is not waiting for the next tap setting (step S611: No), step S612 is skipped and the random number update process 2 is terminated. On the other hand, when the fluctuation pattern random number 3 is waiting for the next tap setting (step S611: Yes), the process proceeds to step S612 to execute the tap setting process.

FIG. 18B shows a specific procedure for the tap setting process in steps S606, S609, and S612.
In the tap setting process, first, the value of the tap counter at that time is acquired (step S621). The tap counter is prepared in the RAM 111C of the gaming microcomputer 111.

  In the next step S622, it is determined whether or not the acquired value of the tap counter matches the previous value. And when it determines with not being in agreement (step S622; No), step S623-S624 is skipped and the said tap setting process is complete | finished. On the other hand, if it is determined in step S622 that the value of the tap counter matches the previous value (step S622: Yes), the process proceeds to step S623.

  In step S623, the value of the tap counter is incremented (+1 updated). In the next step S624, the updated value of the tap counter is set in a tap setting register (608b2) in a random number generation circuit (608) described later. Then, the tap setting process ends.

  As described above, the CPU 111A of the gaming microcomputer 111 updates the tap value that specifies the calculation formulas of the fluctuation pattern random numbers 1, 2, and 3 for determining the fluctuation pattern in the fluctuation display game of the special figure 1 and the special figure 2. To do. As the variation pattern, a variation pattern of “no reach”, “normal reach”, “special (SP) 1-A reach”, “special (SP) 1-B reach”, “special (SP) 2-A”. Fluctuation patterns (reach fluctuation modes) in various reach states such as “reach”, “special (SP) 2-B reach”, “special (SP) 3-A reach”, “special (SP) 3-B reach” are set Has been.

[Prize mouth switch / error monitoring process]
Next, details of the winning opening switch / error monitoring process (step S47) in the above-described timer interrupt process will be described.
The winning opening switch / error monitoring process is a process for monitoring whether or not there is a signal input (signal change) from a switch provided in each of the various winning openings and for monitoring an error.

  As shown in FIG. 19, in the prize opening switch / error monitoring process, first, a prize monitoring table (for example, a list showing switches not requiring error monitoring) of a prize opening switch that does not require an error monitoring process is prepared (step S471). For a winning prize switch that does not require error monitoring processing, error detection is not performed, but winning detection processing is performed. In step S471, a winning monitoring table is prepared for the processing, and the winning number is updated in the next step. Number counter update processing (step S472) is executed. The detailed procedure of the winning number counter updating process will be described later with reference to FIG.

  After the winning number counter updating process (step S472), the error monitoring table of the count switch 38a in the special variable winning device (large winning opening) 38 (for example, the number of the port to which the detection signal from the count switch is input and the signal) (Data indicating the bit position and the like in the port) is prepared (step S473). Then, a prize monitoring process S474 is performed to monitor whether the prize winning opening is illegal even though the prize winning opening is not open, and to detect a normal prize winning. The detailed procedure of the winning monitoring process will be described later with reference to FIG. In other words, the count switch 38a is one of the prize opening switches removed in step S471 because an error monitoring process is necessary.

  After the winning monitoring process (step S474), an error monitoring table of the start port 2 switch 37a in the ordinary electric power (ordinary variable winning device 37) is prepared (step S475). Then, a prize monitoring process S476 is performed to monitor whether there is an illegal winning in the ordinary power even though the ordinary power is not open, and to detect a normal winning. In other words, the start port 2 switch 37a is one of the winning port switches removed in step S471 because error monitoring processing is required.

  Next, an error scan counter for sequentially specifying which switch or signal of the plurality of switches and signals to be monitored for errors is to be monitored this time is updated (step S477). Subsequently, an error monitoring table for monitoring an abnormality of the chute ball switch, overflow switch, and payout control device from the payout control device 200 is prepared (step S478). Then, an error check process S479 for determining whether an abnormality has occurred in these switches and the payout control device with reference to a timer is executed.

  Thereafter, an error monitoring table for monitoring the opening of the front frame (glass frame 15) and the game frame (front frame 12) based on signals from the front frame release detection switch 63 and the game frame release detection switch 64 is prepared (step S480). . Then, an error scan counter for monitoring the opening of the front frame and the game frame is prepared (step S481), and an error check process (step S482) for determining whether an abnormality has occurred in these switches with reference to a timer is executed. To do.

[Input counter update processing]
Next, the details of the input number counter updating process (step S472) in the above-described winning opening switch / error monitoring process will be described.
As shown in FIG. 20, in the input number counter update process, first, the number of winning port switches to be monitored is acquired from the winning monitoring table acquired in step S471 (step S711). Next, the rising edge of the switch input signal saved in the RWM in step S262 of FIG. 11 is acquired (step S712). Then, it is checked whether or not there is an input of detection signals (more precisely, changes in input) from the winning prize switch to be monitored (step S713). If it is determined that there is no input (S714: No), the process jumps to step S719. If it is determined that there is an input (S714: Yes), the value of the winning counter area to be updated is loaded in the next step S715. To do.

  Then, the value loaded in step S715 is updated (+1) to check whether it overflows (step S716). If it is determined that no overflow has occurred (step S717: No), the process proceeds to step S718 to save the updated value in the winning number counter area, and then proceeds to step S719. On the other hand, if it is determined in step S717 that an overflow has occurred (S717; Yes), step S718 is skipped and the process jumps to step S719. For example, in the case where the maximum storage number (for example, 4) is set in advance, such as a start winning prize, the updated value is not saved. In step S719, it is determined whether or not all the switch monitoring processes have been completed. In No), it returns to step S712 and repeats the said process.

[Winning monitoring process]
Next, details of the winning a prize monitoring process (steps S474 and S476) in the above-described winning opening switch / error monitoring process will be described.
The winning monitoring process is a process performed on the count switch 38a of the big winning opening or the start opening 2 switch 37a in the ordinary electric power, and performs illegal monitoring in addition to the detection of the winning. This is because the large winning opening (special variable winning device 38) and the ordinary electric power (ordinary variable winning device 37) are likely to be fraudulently forcibly opening the opening / closing member to insert the game ball and paying out the winning ball.

  As shown in FIG. 21, in the winning monitoring process, first, “0” is set as the added value of the number of illegal winnings (step S741). Then, the rising edge of the switch input signal saved in the RWM in step S262 of FIG. 11 is loaded (step S742). Then, it is checked whether or not there is an input to the winning port switch to be monitored for error (the count switch 38a for the large winning port or the start port 2 switch 37a in the ordinary electric train) (step S743). Here, if it is determined that there is no input (step S744: No), the process jumps to step S746, and if it is determined that there is an input (step S744: Yes), the process proceeds to step S745, and “1” is added as the added value of the illegal winning number. Set and proceed to step S746. In step S746, the fraud monitoring period flag of the winning mouth switch subject to error monitoring is loaded from the RWM.

  Thereafter, an illegal winning error occurrence command of the winning mouth switch subject to error monitoring is acquired (step S747). Then, in the next step S748, it is checked whether it is a fraud monitoring period, that is, a period during which the big prize opening (special variable prize winning device 38) is closed as a gaming state or the ordinary power (normal fluctuation winning prize device 37) is closed. If it is determined that the period is not the monitoring period (step S749: No), the process jumps to step S758. . Here, if it is determined that the unauthorized winning number addition value is “0” (step S751: Yes), the process jumps to step S760, and if it is determined that the unauthorized winning number addition value is not “0” (step S751: No), step Proceeding to S752, "1" is added to the number of illegal winnings subject to error monitoring.

  Next, it is checked whether the number of fraudulent winnings after addition exceeds the number of fraud determinations to be monitored (for example, 5) (step S753). The number of judgments is five, for example, when a large winning opening in the open state is converted to a closed state, the game ball is caught by the door member of the large winning opening, and the gaming ball passes the valid period of the count switch. This is because it is not determined to be illegal when winning a prize or when noise is added to the signal, and it is not determined to be an error easily even if it is not illegal. If it is determined that the number of determinations has not been exceeded (step S754: No), the process jumps to step S758, and if it is determined that the number of determinations has been exceeded (step S754: Yes), the process proceeds to step S755.

  In step S755, the number of fraudulent winnings is limited to the fraud occurrence determination number, and in step S756, an initial value is saved in the notification timer area, and then an error occurrence flag is prepared (step S757). Thereafter, the process proceeds to step S767, where the error flag area of the winning prize switch to be monitored for error is prepared, and the status update process S768 is executed. The status update process will be described later with reference to FIG. 22, but when an error has occurred, an error notification command is transmitted to the effect control device 300 and an error notification is made.

  On the other hand, in step S758, where it is determined that the number of determinations has not been exceeded in step S754 (step S754; No) and the process proceeds to step S758, an error monitoring target winning port switch (a large winning port count switch 38a or a start port 2 in the public power system 2). A winning monitoring table for the switch 37a) is prepared. After that, the winning timer counter is updated, that is, the processing S759 for counting the number of winning prizes as a target for the winning ball discharge is executed, and then the notification timer area is updated (-1) (step S760). Then, in the next step S761, it is determined whether or not the timer has expired. If it is determined that the timer has not expired (step S761: No), the winning monitoring process is temporarily exited. If it is determined that the notification timer has timed out (step S761: Yes), the process proceeds to step S762 to set an illegal winning error cancel command for the winning-watch switch to be monitored for errors. That is, if a predetermined number of illegal prizes do not occur even after a predetermined time has elapsed, an illegal prize error cancel command is set.

  After step S762, an error release flag is prepared (step S763), and it is checked whether the error is released (step S764). Here, if it is determined that it is not the error release timing (step S765: No), the process jumps to step S767, and if it is determined that it is the error release timing (step S765: Yes), the process proceeds to step S766, and the number of illegal winnings is reset. The process proceeds to step S767. In step S767, the error flag area of the winning prize switch to be monitored for error is prepared, and the setting corresponding to the error occurrence flag prepared in step S757 or the error release flag prepared in step S763 is performed, and then the status update process S768 is performed. Transition. The illegal winning error cancel command set in step S762 is transmitted to the effect control device 300 in the status update process S768, and the error notification is cancelled.

[Status update processing]
Next, details of the status update process (step S768) in the above-described winning monitoring process will be described.
As shown in FIG. 22, in the status update process, the error occurrence flag prepared in step S757 or the error release flag prepared in step S763 is changed with the value of the error flag target for error monitoring prepared in step S767. Whether or not (different) is checked (step S681).

  Here, when it is determined that there is no change from the value of the error flag area (step S682: No), the status update process is terminated. When it is determined that the value has changed from the value in the error flag area (step S682: Yes), the process proceeds to step S683, and the error flag is saved in the RWM. Thereafter, an error notification command (MODE) is prepared (step S684), a command setting process (step S685) for transmitting the error notification command to the effect control device 300 is executed, and the status update process ends.

[Special Figure Game Processing]
Next, details of the special game process (step S48) in the above-described timer interrupt process will be described.
In the special figure game process, the input of the start port 1 switch 36a and the start port 2 switch 37a is monitored, the entire process related to the special figure variation display game is controlled, and the special figure display is set.

As shown in FIG. 23, in the special figure game process, first, a start switch monitoring process (step A1) for monitoring winning of the start port 1 switch 36a and the start port 2 switch 37a is performed.
In the start port switch monitoring process, when a game ball is won in the normal variable winning device 37 that forms the start winning port 36 and the second starting winning port, various random numbers (such as jackpot random numbers) are extracted and Prior to the start of the figure variation display game, a game result preliminary determination is performed in which a game result based on a prize is determined in advance.
The details of the start port switch monitoring process (step A1) will be described later.

Next, a count switch monitoring process (step A2) is performed. In this count switch monitoring process, a process of monitoring the count number of the count switch 38a provided in the special variation winning device 38 is performed.
The details of the count switch monitoring process (step A2) will be described later.

Next, the special figure game process timer is updated (-1) to check whether or not the game process timer has expired (step A3), and the special figure game process timer has expired (step A4; If the determination is Yes), a special figure game sequence branch table to be referred to for branching to a process corresponding to the special figure game process number is set in the register (step A5), and the special figure game is used using the table. A process (step A6) of acquiring a branch destination address of the process corresponding to the process number is performed.
Then, after performing the process of saving the return address after the branch process to the stack area (step A7), the game branch process (step A8) is performed according to the game process number.

If the game process number is “0” in step A8, the fluctuation start of the special figure fluctuation display game is monitored, the fluctuation start setting of the special figure fluctuation display game, the setting of the effect, and the special figure fluctuation processing are performed. A special figure routine process (step A9) for setting information necessary for the execution is performed.
The details of the special figure routine process (step A9) will be described later.

If the game process number is “1” in step A8, the special figure changing process for setting the stop display time of the special figure and setting the information necessary for performing the special figure display process is performed. (Step A10) is performed.
The details of the special figure changing process (step A10) will be described later.

In step A8, if the game process number is “2”, if the game result of the special figure variation display game is a big hit, the fanfare command setting corresponding to the big hit type (2R big hit or 15R big hit) Special chart display processing (step A11) for setting the fanfare time according to the big winning opening opening pattern of each jackpot (2R jackpot or 15R jackpot), setting information necessary for performing the fanfare / interval processing, etc. Do.
Details of the special figure display processing (step A11) will be described later.

If the game process number is “3” in step A8, setting of the opening time of the big winning opening, updating of the number of opening, setting of information necessary for performing the processing during opening of the big winning opening, etc. are performed. Processing during fanfare / interval (step A12) is performed.
The details of the fanfare / interval processing (step A12) will be described later.

If the game process number is “4” in step A8, an interval command is set if the big hit round is not the final round, while a big hit end screen command is set if the big round is the final round. A large winning opening opening process (step A13) for setting information necessary for performing the winning opening remaining ball processing is performed.
Details of the special winning opening open process (step A13) will be described later.

If the game process number is “5” in step A8, if the big hit round is the final round, a process for setting a time for discharging the remaining balls in the big prize opening and a big hit end process are performed. A big winning opening remaining ball process (step A14) for setting information necessary for the execution is performed.
Details of the winning prize remaining ball processing (step A14) will be described later.

If the game process number is “6” in step A8, a big hit end process (step A15) for setting information necessary for performing the special figure routine process (step A9) is performed.
The details of the jackpot end process (step A15) will be described later.

Thereafter, each data of the table prepared by the branch process is saved in the work area of the RWM (step A16).
And after preparing the table for controlling the fluctuation | variation of the special figure 1 indicator 51 (step A17), the symbol fluctuation | variation control process (step A18) which concerns on the special figure 1 indicator 51 is performed. Then, after preparing the table for controlling the fluctuation | variation of the special figure 2 indicator 52 (step A19), the symbol fluctuation | variation control process (step A20) which concerns on the special figure 2 indicator 52 is performed.
Details of the symbol variation control process (steps A18 and A20) will be described later.
On the other hand, if it is determined in step A4 that the special figure game process timer has not expired (step A4; No), the process proceeds to step A17, and the subsequent processes are performed.

[Starter switch monitoring process]
Next, details of the start port switch monitoring process in the above-described special figure game process will be described.
As shown in FIG. 24, in the start port switch monitoring process, first, a table for setting a start port winning effect command by the start winning port 36 (first start port) is prepared (step A111), and further, the first start port is set. After preparing the table for setting the hold information by (Step A112), the special start port switch common processing (Step A113) is performed.
The details of the special figure start port switch common process in step A113 will be described later together with the special figure start port switch common process in step A1110.

  Next, it is checked whether or not the ordinary electric accessory (ordinary variation winning device 37) is in operation, that is, whether or not the ordinary variation winning device 37 is activated and the game ball can be won. (Step A114) If it is determined that the ordinary electric accessory is in operation (Step A115; Yes), the process proceeds to Step A118, and the subsequent processes are performed. On the other hand, if it is determined in step A115 that the ordinary electric accessory is not in operation (step A115; No), it is checked whether the number of fraudulent winnings to the normal variable winning device 37 is equal to or greater than the fraud occurrence determination number (step S115). A116), a process of determining whether or not the number of fraudulent winnings is equal to or greater than the fraud determination number (step A117).

  The normal variation winning device 37 cannot win a game ball in the closed state, and can win a game ball only in the open state. Therefore, when the game ball wins in the closed state, it is a case where some abnormality or fraud has occurred. When there is a game ball won in such a closed state, the number is counted as the number of illegal wins. Then, it is determined whether or not the number of illegal winnings thus counted is equal to or greater than a predetermined fraud occurrence determination number (upper limit value).

  If it is determined in step A117 that the number of fraudulent winnings is not greater than or equal to the number of fraud determinations (step A117; No), a table for setting a start opening prize effect command by the normal variation winning device 37 (starting opening 2) is prepared (step A118). ).

Thereafter, after preparing a table for setting information on hold by the start port 2 (step A119), the special start port switch common process (step A120) is performed, and the start port switch monitoring process is terminated.
If it is determined in step A117 that the number of illegal winnings is equal to or greater than the number of fraud determinations (step A117; Yes), the start port switch monitoring process is terminated. That is, the second start memory is not generated any more.

[Special figure start port switch common processing]
Next, details of the special start port switch common process (steps A113 and A120) in the start port switch monitoring process described above will be described.
The special figure start port switch common process is a process performed in common for each input when there is an input from the start port 1 switch 36a or the start port 2 switch 37a.

  As shown in FIG. 25, in the special view start port switch common process, the CPU 111A first starts the monitoring target start port switch (for example, the start port 1 switch 36a) among the start port 1 switch 36a and the start port 2 switch 37a. Is checked (step A201), and if it is determined that there is no input in the monitored start port switch (step A202; No), the special-purpose start port switch common process is terminated. On the other hand, if it is determined in step A202 that there is an input to the monitored start port switch (step A202; Yes), after saving the start port winning flag of the monitored start port switch (step A203), the big hit random number Is loaded (a big hit random number is extracted) (step A204).

  Subsequently, of the start port 1 switch 36a and the start port 2 switch 37a, information regarding the number of winnings to the start port switch to be monitored (for example, the start port 1 switch 36a) is sent to the management device outside the gaming machine 10. On the other hand, the number of times output (starting port signal control output number) is loaded (step A205). Then, the loaded value is updated (+1), it is checked whether or not the output count overflows (step A206), and if it is determined that the output count does not overflow (step A207; No), the updated value is set to RWM. Is saved in the start port signal output frequency area (step A208), and the process proceeds to step A209. On the other hand, if it is determined in step A207 that the number of outputs does not overflow (step A207; Yes), the process proceeds to step A209.

  Then, in step A209, among the start port 1 switch 36a and the start port 2 switch 37a, the update target special figure holding corresponding to the monitored start port switch (for example, the start port 1 switch 36a, etc.) is held (start memory). It is checked whether or not the number is less than the upper limit value (step A209), and processing for determining whether or not the special figure holding number is less than the upper limit value (step A210) is performed.

If it is determined in step A210 that the special figure hold number is not less than the upper limit (step A210; No), it is checked whether or not the input of the start port switch according to step A202 is the input of the start port 1 switch 36a. (Step A211) If it is determined that the input of the start port 1 switch 36a is (Step A212; Yes), a decoration special figure hold number command (overflow command) is prepared (Step A213), and command setting processing (Step A214) is performed. Then, the special figure start port switch common process is terminated.
If it is determined in step A212 that the start port 1 switch 36a is not input (step A212; No), steps A213 to A214 are skipped, and the special drawing start port switch common process is terminated.

On the other hand, if it is determined in step A210 that the special figure hold count is less than the upper limit (step A210; Yes), the update target special figure hold count (for example, special figure 1 hold count, etc.) is updated (+1). After performing the process (step A215), the process (step A216) for calculating the address of the random number save area corresponding to the special figure hold number is performed.
Then, after preparing the decoration special figure reservation number command (MODE) of the start port switch to be monitored (for example, the start port 1 switch 36a) among the start port 1 switch 36a and the start port 2 switch 37a (step A217). ), Load the jackpot symbol random number of the start switch to be monitored (extract the jackpot symbol random number) (step A218), and prepare a decoration special symbol pending number command (ACTION) corresponding to the number of special symbol pending (step) A219), command setting processing (step A220) is performed.

  The jackpot random number is saved in the RWM random number save area (step A221), and the corresponding jackpot symbol random number is saved in the RWM random number save area, and the jackpot symbol random number is saved in the register (step A222). . Thereafter, the process proceeds to step A271 in FIG. 26, and the random number updating notification register (FIG. 48: 608b9) in the random number generation circuit that notifies whether or not the fluctuation pattern random number 1 is being updated is referred to. A determination is made (step A272), and if updating is in progress, the process returns to step S271 and waits for the updating not being performed. If it is determined in step S272 that the update is not in progress (No), the variation pattern random number 1 is loaded from the random number counter (608b7) in the random number generation circuit (608), and the loaded value is saved in the random number save area of the RWM (step A273). ).

Next, in step A274, the random number update informing register for informing whether or not the fluctuation pattern random number 2 is being updated is referred to to determine whether or not it is being updated (step A275). wait. If it is determined in step S275 that it is not being updated (No), the fluctuation pattern random number 2 is loaded, and the loaded value is saved in the random number save area of the RWM (step A276).
Subsequently, in step A277, the random number update notification register that notifies whether or not the fluctuation pattern random number 3 is being updated is referred to, and it is determined whether or not it is being updated (step A278). wait. If it is determined in step S278 that the update is not being performed (No), the fluctuation pattern random number 3 is loaded, and the loaded value is saved in the random number save area of the RWM (step A279). As will be described later, the variation pattern random numbers 1, 2, and 3 are stored in random number counters in different random number generation blocks of the random number generation circuit (608), and each block has a random number updating notification register. Is provided.

From the above description, the CPU 111A functions as a random value acquisition unit that acquires a random value from a random value storage unit (random number counter) when the occurrence of a predetermined random number acquisition condition (winning at the start port) is detected. I understand that. Also, the special figure start port switch common process shown in FIGS. 25 to 26 is a process in the special figure game process of FIG. 23, and the special figure game process is a process in the timer interrupt process of FIG. The random value acquisition by the random value acquisition means is performed during the timer interrupt process.
In addition, the RWM (RAM 111C) extracts various random numbers based on the inflow of game balls to the start area of the start winning opening 36 and the normal variation winning apparatus 37, and can start the stored various random numbers as start memory. Make a storage means.
After step A279, the jackpot symbol random number corresponding to the monitored start port switch saved in the register in step A222 is loaded, and the loaded value is used in the special figure hold information determination process (FIG. 27) described later. (Step A280). Then, a special figure hold information determination process (step A281) is executed, and writing to the update trigger register (FIG. 48: 608b3) in each random number generation block for generating the fluctuation pattern random numbers 1, 2, 3 (steps A282, A283) , A284) are sequentially performed, and the special figure start port switch common processing is terminated. The random number update process in the random number generation block is started by writing to the update trigger register (FIG. 48: 608b3). Therefore, from the above procedure, in this embodiment, an update command for updating the random number value is generated after the random value is acquired.

[Special figure hold information judgment processing]
Next, the details of the special figure hold information determination process (step A281) in the above-described start port switch common process will be described.
The special figure hold information determination process is a look-ahead process for determining the result related information corresponding to the start memory before the start timing of the special figure variation display game based on the corresponding start memory.
As shown in FIG. 27, the CPU 111A first checks whether or not the input of the start port switch according to step A202 of the special-purpose start port switch common process is the input of the start port 2 switch 37a (step A231). If it is determined that the input to the start port 2 switch 37a is not input (step A232; No), the open extension function of the normal variation winning device 37 is operating, that is, the normal variation winning device 37 is being supported (during the short-time operation state). A process for determining whether or not (step A233) is performed.
Here, if it is determined that the normal variation winning device 37 is not being supported (step A233; No), a process of determining whether or not the gaming machine 10 is in a big hit (special game state) (step A234) is performed.

  If it is determined in step A234 that the jackpot is not being hit (step A234; No), the jackpot determination process for determining whether or not the acquired jackpot random number value matches the jackpot determination value is a jackpot determination process (step A235) is performed. The jackpot determination process in step A235 is the same as the jackpot determination process in the special figure routine process (see FIG. 32), and details thereof will be described later.

On the other hand, if it is determined in step A233 that the normally variable winning device 37 is being supported (step A233; Yes), or if it is determined in step A234 that it is a big hit (step A234). ; Yes), the special figure hold information determination process is terminated.
In other words, when the input of the start port switch according to step A202 of the special-purpose start port switch common processing is the start port 1 switch 36a, when the normal variation winning device 37 is being supported or is a big hit, the start memory is stored in the start memory. The prefetch process for determining the corresponding result related information is not performed.

If it is determined in step A232 that the input is the start port 2 switch 37a (step A232; Yes), the process proceeds to step A235 without performing the processes in step A233 and step A234. The subsequent processing is performed.
In other words, when the input of the start port switch according to step A202 of the special figure start port switch common processing is the start port 2 switch 37a, the start is performed regardless of whether the normal variation winning device 37 is being supported or the big hit. A prefetching process for determining the result related information corresponding to the storage is performed.

And after performing the process (step A236) which sets a loss information table, if it determines with the determination result of the big hit determination process in step A235 not being a big hit (step A237; No), a process will transfer to step A245.
On the other hand, if it is determined that the determination result of the jackpot determination process in step A235 is a jackpot (step A237; Yes), the jackpot symbol random number check table 1 is prepared (step A238).

Next, it is checked whether or not the input of the start port switch according to step A202 of the special processing of the start port switch is the input of the start port 1 switch 36a (step A239), and it is not the input of the start port 1 switch 36a. If it determines with (step A240; No), it replaces with the jackpot symbol random number check table 1 prepared at step A238, and the jackpot symbol random number check table 2 is prepared (step A241).
Then, after performing a process of acquiring a winning information pointer corresponding to the jackpot symbol random number (step A242), a process of setting the address table of the jackpot information table (step A243) is performed, and the jackpot information corresponding to the winning information pointer A process of acquiring a table (step A244) is performed.
If it is determined in step A240 that the input is the start port 1 switch 36a (step A240; Yes), the process proceeds to step A242, and the big hit symbol random number check table 1 prepared in step A238 is displayed. Based on this, the subsequent processing is performed.

Next, a process for obtaining start opening prize effect information from the jackpot information table (step A245) is performed, and the start opening prize effect information is saved in the symbol information area for work of the RWM (step A246).
Subsequently, a process for obtaining a start opening prize effect symbol command from the jackpot information table (step A247) is performed, and the start opening prize effect symbol command is saved in the winning effect symbol command area of the RWM (step A248).

Next, after preparing the start port winning flag of the start port switch to be monitored among the start port 1 switch 36a and the start port 2 switch 37a (step A249), the special information set for the start port to be monitored Special figure information setting processing (step A250) is performed. Subsequently, after performing the latter half variation pattern setting process (step A251) for setting the latter half variation pattern among the variation modes in the special figure variation display game, the variation pattern setting process (step A251) is performed. Step A252) is performed.
Note that the special figure information setting process in step A250, the latter half fluctuation pattern setting process in step A251, and the fluctuation pattern setting process in step A252 are the special figure information setting process in the special figure usual process (see FIG. 35), the latter half fluctuation pattern, respectively. This is the same as the setting process (see FIG. 36) and the variation pattern setting process (see FIG. 37), and details thereof will be described later.

Then, a start opening winning effect command corresponding to the variation pattern is prepared (step A253), and a command setting process (step A254) is performed. Subsequently, a start opening winning effect command command is loaded and prepared from the winning effect symbol command area (step A255), a command setting process (step A256) is performed, and the special figure hold information determination process is terminated.
That is, a start opening prize command command is prepared in step A253, and a starting opening prize drawing command command is prepared in step A255, so that the determination result (prefetch result) of the result related information corresponding to the start memory can be handled. The effect control device 300 can be notified before the start timing of the special figure variation display game based on the starting memory to be performed, and in particular, by changing the number of special figure hold displayed on the display device 41, the special figure The result related information can be notified to the player before the start timing of the variable display game.
Further, as described above, the CPU 111A determines a variation pattern (effect mode) based on the variation pattern random numbers 1, 2, and 3, and a command corresponding to the determined variation pattern (effect control command). Is transmitted to the effect control device 300 in the aforementioned effect control command transmission process (FIG. 14). Therefore, the CPU 111A selects an effect mode to be used for the effect of the variable display game from a plurality of effect modes prepared in advance based on the random number value, and determines an effect control command corresponding to the selected effect mode. It functions as production control command determination means.

[Count switch monitoring processing]
Next, details of the count switch monitoring process in the special figure game process described above will be described.
As shown in FIG. 28, in the count switch monitoring process, first, it is checked whether or not the special prize-winning device 38 is open (step A261), and the special prize-winning mouth is being opened (step A261).

Next, details of the usual game process (step S49) in the above-described timer interrupt process will be described.
In the usual game process, the input of the gate switch 34a is monitored, the whole process related to the usual figure change display game is controlled, and the display of the usual figure is set.

  Next, the configuration of the gaming microcomputer 111 constituting the gaming machine control system of FIG. 3 will be described with reference to FIG. FIG. 47 shows a block diagram of the gaming microcomputer 111. The gaming microcomputer 111 is manufactured as an IC for a so-called amusement chip (hereinafter referred to as a gaming arithmetic processing device 600), and is divided into a gaming area unit 600A for performing gaming control and an information area unit 600B for managing information. Can do.

  Among these, the game area unit 600A includes a CPU core 601, a user program ROM 602, an HW parameter ROM 603 (collectively referred to as ROM), a user work RAM 604 and a mirrored RAM 605 (collectively referred to as RAM), and an external bus interface (I / F) 606. , Bus switching circuit 607, random number generation circuit 608, clock generator 609, reset / interrupt control circuit 610, address decoder 611, output control circuit 612, boot block 613, decoding / ROM writing circuit 614, bus 615, etc. Composed. In the game arithmetic processing device 600 of this embodiment, the random number generation circuit 608 is formed as an on-chip circuit, but the random number generation circuit 608 may be formed as a separate IC outside the chip.

  The CPU core 601 includes various register groups, an arithmetic / logic unit (ALU), an instruction register (IR), a decoder, a program counter (PC), a stack pointer (SP), a data bus connecting them, an address bus, and various control units. In the core, for example, configured with Z80 architecture. The CPU core 601 (111A) implements various functions necessary for controlling the gaming machine 10 in software by loading and executing the game control program and the effect control program stored in the user program ROM 602 (111B). To do. The control program stored in the user program ROM 602 is a game control program for controlling a game when the game calculation processing device 600 is the game microcomputer 111 provided in the game control device 100. When the device 600 is a game microcomputer of the payout control device 200, the payout control program controls a ball payout device that pays out game balls.

  The HW parameter ROM 603 is a memory that stores validity confirmation information. The legitimacy confirmation information is information for checking whether or not the gaming arithmetic processing unit 600 is legitimate. For example, a unique ID indicating a unique identifier of the pachinko gaming machine 10, a manufacturer code (pachinko game) Unique identifier assigned to each machine manufacturer), rank code indicating the rank (1 type, 2 type, etc.) of pachinko machines, and model code set by the manufacturer for the type of pachinko machine An inspection code indicating an inspection number, a RAM backup code indicating whether or not to back up the RAM when the power is turned on, a lending fee set by a lending fee setting switch, and the like. Further, the HW parameter ROM 603 stores only one unique ID that is a unique identifier of the inspection apparatus that first transmitted the lending information request. When the third party organization or the manufacturer of the pachinko gaming machine writes the program in the user program ROM 602, the validity confirmation information is written in the HW parameter ROM 603.

  When checking the validity of the gaming arithmetic processing device 600, when the gaming arithmetic processing device 600 is powered on, the arithmetic value calculated by the gaming arithmetic processing device 600 itself and the legitimacy confirmation information (ie, third party) It is configured to check whether or not the gaming arithmetic processing device 600 is legitimate by comparing and determining with a result value set in advance by an engine or the like.

  The user work RAM 604 (111C) is used as a work area (work area) when executing processing based on a program in the game area unit 600A. The mirrored RAM 605 stores information obtained by copying information stored in the user work area when the clock falls (if the CPU core is Z80, the mirrored RAM 605 executes processing when the clock rises, and thus can move in synchronization. Not to do that.)

  The external bus interface 606 has interfaces such as a memory request signal MREQ, an input / output request signal IORQ, a memory write signal WR, a memory read signal RD, and a mode signal MODE, and the bus switching circuit 607 is a 16-bit interface. It is an interface for address signals A0 to A15 and 8-bit data signals D0 to D7. For example, if the data signals D0 to D7 are added while sequentially increasing the address signals A0 to A15 while the MODE signal is set to [H] level, the writing mode to the user program ROM 602 is set and the pachinko gaming machine 1 The program can be written by the manufacturer or a third party.

  Note that the write mode allows a program to be written, and does not allow a boot program stored in the boot block 613 to be written. Further, when the writing of the program to the user program ROM 602 is completed, a writing end code is recorded in a predetermined area of the HW parameter ROM 603 (for example, recorded by physically cutting a predetermined code or a predetermined bit). Thus, when a write end code is recorded in the HW parameter ROM 603, a new program cannot be written in the user program ROM 602.

  The random number generation circuit 608 generates a random number related to game control in the game execution process (the random number is used for determination of winning or determination of symbols at the time of stopping, etc.). In addition to generating a uniform random number using a sequence method, etc., it has a function of generating a random number using a counter method. Note that when the gaming arithmetic processing device 600 is the gaming microcomputer 211 provided in the payout control device 200, the random number generation circuit 608 may not be provided.

  The clock generator 609 generates an internal clock signal and further divides the generated clock signal to generate a signal related to timing necessary for game control (details will be described later in FIG. 48). A reset / interrupt control circuit (interrupt signal generation means) 610 detects a reset interrupt signal RST from an interrupt signal generation circuit (not shown) and notifies the CPU core 601 and the random number update controller 608a. The address decoder 611 decodes the location of the built-in device and the built-in control / status register group by the memory mapped I / O method and the I / O mapped I / O method.

  The output control circuit 612 performs signal control from the address decoder 611 and outputs an 8-bit chip select signal (CS0 to CS7) from the external terminal. The boot block 613 stores a boot program and initializes information stored in the user work RAM 604 when power is turned on.

  The decoding / ROM writing circuit 614 is used in the writing mode to the user program ROM 602 and the HW parameter ROM 603, and passes through the bus switching circuit 607 while the mode signal MODE is at the [H] level. The address signals A0 to A15 and the data signals D0 to D7 are fetched and the information (encrypted program and encrypted unique ID after change) included in the data signals D0 to D7 is decrypted, and then the bus The data is output (written) to the user program ROM 602 and the HW parameter ROM 603 via 615. The bus 615 includes a data bus, an address bus, and a control bus, and the information area unit 600B is also connected to the bus 615.

  An information area 600B for managing information in the game processing unit 600 includes an HPG program ROM 616, an ID property memory 617, a bus monitor circuit 618, an HPG work RAM 619, a control circuit 620, an external communication control circuit 621, a bus 622, and a game. A part of the bus 615 extending from the region 600A is included.

  The HPG program ROM 616 in the information area 600B stores HPG programs that perform various inspection operations. In the ID property memory 617, based on a request received from the inspection device (not shown) via the external communication control circuit 621, information stored in the HW parameter ROM 603 can be immediately output to the inspection device. The information stored in the HW parameter is duplicated and stored when the computer processing unit 600 is powered on (system reset). The ID property memory 617 is configured to be accessible from both the game area 600A side and the information area unit 600B side.

  The bus monitor circuit 618 monitors and controls the state of the bus 615 on the game area 600A side from the information area 600B side. The control here refers to timing control when copying the contents of the HW parameter ROM 603 to the ID property memory 617, or when outputting the program stored in the user program ROM 602 to the outside (the bus 615 on the gaming area unit 600A side) Timing control at the time of opening and reading a program from the user program ROM 602 and outputting it to the outside from the information area 600B side. The program is output after being encrypted by the external communication control circuit 621. The HPG work RAM 619 is used as a work area (work area) when executing processing based on a program in the information area unit 600B.

  The control circuit 620 controls the information area 600B side and has a buffer memory. For example, the control circuit 620 monitors the operation of the CPU core 601 via the bus monitor circuit 618, and copies the content stored in the user work RAM 604 of the game area unit 600A to the mirrored RAM 605 during non-operation. Further, the contents of the ID property memory 617 of the information area unit 600B are transferred to the outside in response to a request from the inspection apparatus, or the program in the user program ROM 602 is externally transmitted via the bus monitor circuit 618 in response to a program request. Or transfer to. The memory of the control circuit 620 is used for timing adjustment at the time of transfer.

  The external communication control circuit 621 performs communication with the inspection device. For example, information (for example, a unique ID, a program, an actual payout number, etc.) stored in the game processing device 600 based on an external command. ) Is encrypted and then transferred to the outside. In the game processing unit 600, the game area unit 600A and the information area unit 600B operate independently via the bus monitor circuit 618. That is, the information area unit 600B side can operate regardless of the operation of the CPU core 601 in the game area unit 600A (regardless of program execution). Various devices constituting the game area portion 600A and the information area portion 600B are mounted on a common semiconductor substrate and packaged as one chip.

Next, a random number generation circuit and a clock generator that are provided in the game processing unit 600 and are used to generate a winning random number and the like will be described in detail.
FIG. 48 is a block diagram showing details of the random number generation circuit 608 in the game processing unit 600 according to the embodiment of the present invention. In addition to the random number generation circuit 608, the gaming arithmetic processing device 600 receives the reset signal RST from the reset signal generation circuit in the power supply device 400 and generates an interrupt signal for the random number generation circuit 608 and the gaming arithmetic processing device 600. A clock generator 609 for generating a plurality of clock signals used in the game processing unit 600 based on the reset interrupt control circuit 610 and the original clock signal CLK supplied from the external crystal oscillation circuit 113 is provided.

  The clock generator 609 includes a CTC circuit 609a and a frequency dividing circuit 609b, and the frequency dividing circuit 609b divides the original clock signal CLK inputted from the crystal oscillation circuit 113 outside the game processing unit 600. The clock signal φ1 having a cycle twice that of the original clock signal is generated and supplied to the controller 608a of the random number generation circuit 608, and the clock signal φ2 having a cycle longer than that of the original clock signal CLK is generated to the CTC circuit 609a. input. A CTC (Counter / Timer Circuit) circuit 609a supplies the CPU 601 with a timer interrupt signal (CTC1) having a predetermined period (for example, 2 milliseconds) and a random number controller 608a based on the clock signal φ2 from the frequency dividing circuit 609b. A signal CTC2 that gives a trigger for updating the random number to be generated is generated. Therefore, the signal CTC2 supplied from the CTC circuit 609a to the random number controller 608a can be regarded as an update command signal for updating the random number value. The CTC circuit 609a is configured so that the period of the generated signals CTC1 and CTC2 can be set freely.

The random number generation circuit (random number generation means) 608 includes a random number update controller 608a, a first random number block 608b, a second random number block 608c, a third random number block 608d, a fourth random number block 608e, a fifth random number block 608f, and a sixth random number block. 608g and a random number circuit 608h. Among them, the second random number block 608c to the sixth random number block 608g have the same configuration as the first random number block 608b, and the random number circuit 608h is a complete hard random number circuit including only a random number counter and a circuit such as a work area that cannot be operated by the CPU 111A. It is configured as.
In this embodiment, for example, the first random number block 608b generates a hit random number (common figure), the second random number block 608c generates a big hit symbol random number 1, and the third random number block 608d generates a big hit symbol random number 2. The fourth random number block 608e generates the fluctuation pattern random number 1, the fifth random number block 608f generates the fluctuation pattern random number 2, the sixth random number block 608g generates the fluctuation pattern random number 3, and the random number circuit 608h Used to generate a big hit random number.

  A random number update controller (update control means) 608a performs arithmetic processing for determining whether or not to give a game value (for example, jackpot) in the process of executing game control, and for generating random numbers used to determine the control state A random number is generated using a mathematical method (for example, a congruent method or an M-sequence method) that generates a uniform random number. Further, the random number update controller 608a can receive an interrupt signal from the reset interrupt control circuit 610 and signals (CTC2, φ1) from the CTC circuit 609a and the frequency dividing circuit 609b as signal generating means constituting the clock generator 609. It has become.

  Although not particularly limited, the random number generation circuit 608 according to the present embodiment has a signal CTC2 input from the CTC circuit 609a in the clock generator 609 and a random number update trigger register (608b3) by the CPU 601 as described later. The random number update process can be performed by any of the settings. Therefore, the input of the signal CTC2 and the writing of the random number update trigger register (608b3) by the CPU 601 are the update commands. Further, as will be described later, the random number generation circuit 608 is configured to select either a counter method, that is, a mode for generating a random number by updating the counter value by −1 or a mode for generating an M-sequence random number. ing.

The first random number block 608b includes a CTC update permission register 608b1, a tap setting register 608b2, a random number update trigger register 608b3, a maximum value setting register (range information storage means) 608b4, a start value setting register 608b5, a round completion notification register 608b6, a random number counter 608 b 7, work area 608 b 8, random number updating notification register 608 b 9, update error notification register 608 b 10, random number circuit reset register 608 b 11, round counter 608 b 12 that counts the number of rounds of random number counter 608 b 7, and count counter that counts the number of times the divided signal φ 1 is input 608b13, initial value counter 608b14 that generates a different value every time the power is turned on (including when the system is reset), setting information storage indicating the update state of a register in the random number generation circuit, etc. Composed of such soft random status register 608b15 as stage.
In the soft random number status register 608b15, information (start value setting bit) indicating whether or not the start value (start value) to be set next time is stored in the start value setting register 608b5 and the tap setting register 608b2 next time. Information (tap value setting bit) indicating whether or not a tap value (index) to be set is stored is provided.

  Among the above registers, the work area (update means) 608b8, the initial value counter 608b14, and the soft random number status register 608b15 are registers that cannot be accessed by the CPU core 601, that is, the user program. The random number counter 608b7 is a register that can be accessed from both the random number update controller 608a and the user program. Before the tap setting register 608b2 is set, the user program accesses on condition that access by the random number update controller 608a is permitted. Can be done.

  The second random number block 608c, the third random number block 608d, and the fourth random number block 608e have the same configuration as that of the first random number block 608b, and thus the description thereof is omitted. By providing a plurality of random number blocks, a plurality of random numbers used in game control can be generated in parallel. In this embodiment, a big hit random number (common to both special figure 1 and special figure 2) for determining whether or not to generate a big hit in the special figure variable display game, and a big hit in each variable display game of special figure 1 and special figure 2 The jackpot symbol random numbers 1 and 2 that determine the stop symbol, and the hit random numbers that determine whether or not to generate a hit in the normal variation display game, are generated in parallel. May be generated.

  The CTC update permission register 608b1 sets whether or not the update of the random number counter 608b7 is permitted / not permitted. Will be updated. The tap setting register 608b2 operates the random number counter 608b7 in the “counter mode” and is “0” when the power is turned on. At this time, the random number counter 608b7 does not operate. . Then, when a value other than “0” is written in the tap setting register 608b2, the random number counter 608b7 operates. In the case of the “random number mode”, the type of M-sequence recurrence formula is determined by the value written in the tap setting register 608 b 2. Therefore, the tap setting register 608b2 functions as activation information storage means for storing activation information indicating whether or not to start updating the random number value.

  The random number update trigger register 608b3 is a register that can be directly written from the CPU core 601, and when the CPU core 601 writes a predetermined value by, for example, interrupt processing, the random number update controller 608a recognizes it and updates the random number counter 608b7. It is configured as follows. At this time, the random number counter 608b7 is updated regardless of whether the setting of the CTC update permission register 608b1 is “permitted” / “not permitted”. Accordingly, the random number update trigger register 608b3 functions as an update instruction storage unit that instructs to update the random number value.

  The maximum value setting register 608b4 sets the maximum value and mode of the random number counter 608b7. The maximum value is set to a value between 8 and 4095. The mode is set to either “random number mode” or “counter mode”. When the set maximum value is N, the random number counter 608b7 is updated in the range of 1 to N in the “random number mode”, and the random number counter 608b7 is updated in the range of 0 to N in the “counter mode”. Therefore, the maximum value setting register 608b4 functions as range information storage means for storing the update range information of the random number generation circuit 608. In this embodiment, the maximum value of the random number per common figure is set to 250, for example, and the maximum value of the special figure big hit symbol random numbers 1 and 2 is set to 200, for example.

  The start value setting register 608b5 is for the CPU core 601 to set (store) the update start value (start value) of the random number counter 608b7 by the user program. When the random number counter 608b7 makes a predetermined cycle once, this random number update controller 608a sets this start value in the random number counter 608b7. Specifically, for example, when a value larger than the maximum value N set in the maximum value setting register 608b4 is set as the start value S, the maximum value N when the random number counter 608b7 makes one round of a predetermined cycle. Is divided by the start value S, the remainder value is set in the random number counter 608b7. Accordingly, the start value setting register 608b5 functions as a start value storage unit that stores the start value of the random number value, and the random number update controller 608a functions as a start value setting unit.

  The one-round completion notification register 608b6 notifies that the random number counter 608b7 has made a predetermined cycle once. When the CPU core 601 sets a start value in the start value setting register 608b5, it is set to ON and set to ON. After that, when the random number counter 608b7 makes one round of a predetermined cycle and the start value of the start value setting register 608b5 is reset in the random number counter 608b7, the one-round completion notification register 608b6 is set to OFF. Then, the circulation counter 608b12 counts the number of circulations of the random number counter 608b7.

  The random number counter 608b7 is composed of a 12th-order (12-bit) random number sequence, and until a predetermined value is written to the tap setting register 608b2, data can be set and the start value when the random number is turned on can be changed. it can. Therefore, the range of the random number counter 608b7 can take a value between 1 and 4095 in the “random number mode”, and can take a value between 0 and 4095 in the “counter mode”. Become. Further, in the “random number mode”, the same random number value is not generated until the counter value makes one round.

  The work area 608b8 is composed of a RAM or a non-volatile memory backed up by a backup power source, and functions as an update buffer and a backup area for the random number counter 608b7. The work area 608b8 is updated by updating random numbers. The value is stored in the random number counter 608b7. Accordingly, the work area 608b8 functions as a random number update unit, and the random number counter 608b7 functions as a random value storage unit. The work area 608b8 is a register that cannot be read from the CPU, thereby preventing an indeterminate value being updated from being erroneously taken into the CPU. The work area 608b8 is divided into a plurality of areas, and one of the areas holds the value of the initial value counter 608b14 immediately before the power failure when a power failure occurs. Hereinafter, this area is referred to as a backup area, and is distinguished from a random number update area in which a random value is entered.

  When the random number value in the work area 608b8 is instructed to be updated by writing the signal CTC2 from the CTC circuit 609a or the random number update trigger register 608b3, the random number value is continuously updated until it reaches a value in the range indicated by the maximum value setting register 608b4. . While the value in the work area 608b8 is being updated, “0” is set in the random number counter 608b7 regardless of whether it is in the “random number mode” or the “counter mode”. Therefore, in the “random number mode”, if “0” that does not belong to the numerical value (1 to N) within the update range is set in the random number counter 608b7, it indicates that the random number counter 608b7 is being updated. Therefore, the value of the random number counter 608b7 can be regarded as updating information indicating whether or not the random number value is being updated. In the “counter mode”, the count value is updated (−1) in the work area 608b8 by the down-count method.

  The random number updating notification register 608b9 notifies that the random number is being updated, and is set to ON while the random number counter 608b7 is being updated by the CTC circuit 609a or the random number update trigger register 608b3 as a signal generating means. If it is not being updated, it is set to off. Therefore, the random number updating notification register 608b9 functions as an updating information storage unit that stores updating information indicating whether or not the random number value is being updated.

  In the update error notification register 608b10, when the value of the random number counter 608b7 is not updated, a value indicating an error is set by the random number update controller 608a. It is possible to know whether or not. Therefore, the update error notification register 608 b 10 functions as an abnormality information storage unit of the random number generation circuit 608. An update error, that is, whether or not the value of the work area 608b8 has been updated can be determined by the random number update controller 608a.

  The random number circuit reset register 608b11 is for resetting the random number generation circuit 608 from the outside when a random number update error occurs. When the CPU 601 writes a predetermined value in this register, the random number update controller 608a receives a reset command. It is determined that the circuit is in the reset state. The number counter 608b13 counts the number of times the divided signal φ1 is input.

  The initial value counter 608b14 is updated (+1) by the interrupt processing of the random number update controller 608a every time the frequency division signal φ1 from the frequency dividing circuit 609b is input. The value of 608b14 is stored in the work area 608b8, and the value is restored when the power is turned on (including when the system is reset), thereby functioning as an initial value generating circuit that generates a different value every time the power is turned on. The soft random number status register 608b15 is a setting information storage unit in which information (flag) indicating whether or not a value (start value) to be set next time is stored in the start value setting register 608b5 is stored by the random number update controller 608a. Function as. In the present embodiment, the original clock signal CLK is divided by two to generate the clock signal φ1 having a cycle twice the cycle of the original clock signal, but the cycle of the clock signal φ1 is limited thereto. Not.

  Here, in the present embodiment, the outline of the initial value (start value) agitation update process that makes it difficult for fraud related to the random number generation process by the random number counter 608b7 in the random number generation circuit 608 by software (user program). This will be described with reference to FIG. In the present embodiment, this process is applied to the jackpot symbol random numbers 1 and 2 for determining the jackpot stop symbol in each variable display game of the special chart 1 and the special chart 2, and the hit in the general chart variable display game. This is a process for generating a total of three random numbers (not including the big hit random number), which is a random number for determining whether to generate or not, and here, the usual random number agitation update process will be described.

  FIG. 49A is a conceptual diagram of a random number counter 608b7 that generates a normal hit random number. FIG. 49B shows an initial value (start value) that is reset in the random number counter 608b every time the random number counter 608b7 makes a round. It is a conceptual diagram of the initial value random number counter to produce | generate. The random number counter in FIG. 49A is updated (−1) every time the periodic signal CTC2 output from the CTC circuit 609a is input to the random number update controller 608a. The initial value random number counter is a counter provided in the user work RAM 604 in the game processing device 600 of FIG. 47, and is updated (+1) by the user program (initial value random number update process of FIG. 8 of the main process). FIG. 49 shows an example in which the initial value random number counter is composed of 8 bits and “250” is set as the maximum value of the random number counter 608b7. When “N” is set as the maximum value in the maximum value setting register 608b4, the random number counter of FIG. 49A operates as a counter with the maximum value MAX being “N”.

  In this embodiment, when the power is turned on and the system is reset, the value of the initial value counter 608b14 that is restored from the work area 608b8 in the random number generation circuit 608 and becomes a random value every time (“2” in FIG. 49) The initial value is set in the random number counter 608b7 of FIG. 49 (A) and the initial value random number counter (replacement counter) of FIG. 49 (B) (symbol # 1). After that, the random number counter 608b7 in FIG. 49A and the initial value random number counter in FIG. 49B are updated (−1 or +1) at different timings (symbol # 2).

  After that, the value of the initial value random number counter in (B) is the value Ni (“149” in FIG. 49) at that time in the random number update process (S45, FIG. 17) in the timer interrupt process (FIG. 9) of the CPU. It is set in the start value setting register 608b5 (symbol # 3). Then, when the random number counter 608b7 goes around (symbol # 4), the value of the start value setting register 608b5 is reset to the random number counter 608b7 as an initial value (start value) in the next counting cycle, that is, the start value is replaced. (Symbol # 5). Then, the random number counter 608b7 is updated (−1) each time the signal CTC2 is input with the set value Ni (= 149) as an initial value (start value) (reference # 6).

  On the other hand, the initial value random number counter of FIG. 49 (B) is continuously updated (+1) even after the count value Ni (= 149) is set in the start value setting register 608b5 (symbol # 3 '). The initial value (start value) is reset (replaced) in the random number counter 608b7 by storing the value of the start value setting register 608b5 in the work area 608b8, not directly. This is because the value of the random number counter 608b7 is not directly updated, but the actual update is performed in the work area 608b8, and the update result is stored in the random number counter 608b7. Through the processing as described above, the start value of the random number counter 608b7 is agitated, and it is possible to prevent fraud related to random number acquisition from being performed.

  That is, even if the fraudster determines the update timing of the random number counter based on, for example, the transmission timing of the control signal from the game control device of the gaming machine to the various controlled devices, the mechanism for changing the initial value of the lap Unless it is analyzed, it is difficult to determine the value of the random number counter, and it is extremely difficult to perform an illegal act that generates a specific gaming state (big hit state). A random value is generated by the random number generation circuit every time the power is turned on and the system is reset, and a replacement counter that generates the initial value of the first round of the random number counter and the initial value (start value) of the second and subsequent rounds is generated. Since it is set as an initial value, it is difficult to determine the value of the random number counter from the outside, and illegal acts can be prevented in advance.

  Next, a control procedure in the random number generation circuit 608 by the random number update controller 608a will be described. FIG. 50 shows a flowchart of the first half of the main processing by the random number update controller, and FIG. 51 shows a flowchart of the second half of the main processing by the random number update controller. This main process is a loop process that is started every time the power is turned on and the system is reset and is continuously executed while the power is turned on. There are an interrupt process by the input of signals φ1 and CTC2 and an emergency interrupt process that is executed when power interruption is detected. The storage of the value of the initial value counter 608b14 in the work area 608b8 (backup area) can be performed by an emergency interrupt process when power-off is detected.

  The random number update controller 608a starts the control flow of FIG. 50 based on the reset interrupt signal from the reset interrupt control circuit 610 or the power-on reset signal when the power is turned on. First, the values stored in the work area 608b8 are excluded. The values stored in other storage areas and registers are initialized (step S101). At this time, the value of the circulation counter 608b12 is set to “0”. Also, with this initialization process, the value of the initial value counter stored in the backup area of the work area 608b8 can be returned to the initial value counter 608b14.

  Next, the value of the initial value counter stored in the backup area of the work area 608b8 is taken into the random number counter 608b7 (step S102). Subsequently, the change of the random number counter 608b7 by the user program is permitted (step S103), and the setting of the tap setting register 608b2 is awaited (step S104). The change of the random number counter 608b7 is permitted, and the value “0” is written to the tap setting register 608b2, so that the random number counter 608b7 can be updated by writing a predetermined value to the CTC2 signal or the random number update trigger register 608b3. . Therefore, the initial value counter 608b14 and step S102 function as first agitation means that generates a random value every time the power is turned on and the system is reset, and sets it as the initial circulation initial value of the random number counter. Become.

  Thereafter, the random number update controller 608a prohibits the change of the random number counter 608b7 (step S105), stores the value of the random number counter 608b7 at this time in the work area 608b8 (step S106), and the value of the random number counter set by the user After executing random number counter initial value correction processing (step S160, FIG. 52) for correcting the value to a value within a predetermined range, the number counter 608b13 is set to “0” (step S107). Until the change of the random number counter 608b7 is prohibited, an arbitrary value can be directly written to the random number counter 608b7 by the CPU core 601 (FIG. 47). Even if the change of the random number counter 608b7 is prohibited, the update by the random number update controller 608a can be performed at any time.

Next, it is determined whether or not the CTC signal (CTC2) is generated (detected) by the CTC circuit 609a (step S108). In the determination of whether or not the CTC signal is generated by the CTC circuit 609a (step S108), if the CTC signal is generated by the CTC circuit 609a (Yes), it is determined whether or not the CTC use mode is set. It is determined whether or not the permission register 608b1 is set to “permitted” (step S109).
In the determination of whether or not the mode is the CTC use mode (step S109), if the mode is the CTC use mode (Yes), the process proceeds to step S111. On the other hand, if it is not in the CTC use mode in the determination of whether or not it is in the CTC use mode (step S109), that is, if the CTC update permission register 608b1 is set to “impossible” (No), the random number update trigger register 608b3 It is determined whether or not a predetermined value is written in (Step S110).

  In the determination of whether or not the CTC signal is generated by the CTC circuit 609a (step S108), if the CTC signal is not generated by the CTC circuit 609a (No), step S109 is skipped and the random number update trigger register is registered. It is determined whether a predetermined value is written in 608b3 (step S110). In this determination (step S110), when a predetermined value is written in the random number update trigger register 608b3 (Yes), the process proceeds to step S111. On the other hand, when it is determined in step S110 that the predetermined value is not written in the random number update trigger register 608b3 (No), the process returns to step S108.

  Next, after the random number updating notification register 608b9 is set to ON (step S111), the value of the random number counter 608b7 is set to “0” (step S112), and the frequency dividing signal φ1 is input from the frequency dividing circuit 609b. Wait (step S113). Then, it is determined whether the mode set in the maximum value setting register 608b4 is the “random number mode” or the “counter mode” (step S114). In this determination (step S114), when the mode set in the maximum value setting register 608b4 is “counter mode”, it is determined whether or not the value of the work area 608b8 is larger than “0” (step S115).

  In the determination of whether or not the value of the work area 608b8 is greater than “0” (step S115), if the value of the work area 608b8 is determined to be “0” (= No), the value of the work area 608b8 is maximized. A value is set (step S116). On the other hand, if it is determined that the value of the work area 608b8 is greater than “0” (step S115) and the value of the work area 608b8 is greater than “0” (Yes), the value of the work area 608b8 is determined. Is decremented (-1 updated) (step S117).

  Thereafter, it is determined whether the information (start value setting bit) of the soft random number status register 608b15 indicating whether or not the start value (start value) to be set next time is stored in the start value setting register 608b5 is turned off ( Step S118). If the flag is not turned off, that is, if a new start value is not stored (No), the process jumps to step S121. If it is determined in step S118 that the start value setting bit is off (Yes), the start value set in the start value setting register 608b5 and the work area 608b8 are stored in the next step S119. The value of the initial value counter is compared to determine whether or not it matches the previous value. If it is determined in step S119 that they match (Yes), the process jumps to step S121. If it is determined in step S119 that they do not match (No), the next step S120 stores the soft random number status register 608b15. The start value setting bit is set to ON, and the process proceeds to step S121.

  In step S121, the value of the lap counter 608b12 is incremented (+1 updated), and it is determined whether or not the value of the lap counter is greater than or equal to the maximum value of the random number counter (step S122). If the value of the circulation counter is equal to or greater than the value added to the maximum value of the random number counter 608b7 (step S122; Yes), the value of the circulation counter is set to “0” (step S123). On the other hand, in the determination of whether or not the value of the lap counter is equal to or larger than the value added to the maximum value of the random number counter 608b7 (step S122), the value of the lap counter is not equal to or larger than the value added to the maximum value of the random number counter 608b7. In step S122; No, the process proceeds to step S147 in FIG. 51 (symbol B). Therefore, step S122 functions as a round detection means.

Next, the start value setting register 608b5 acquires the start value for random number update and corrects it to be equal to or less than the maximum value (step S124). As shown in FIG. 49, when the range of the initial value random number counter (B) is larger than that of the hit random number counter (A), a value that the hit random number counter cannot take is acquired as a start value from the initial value random number counter. Is taken into account.
Specifically, at this time, if the acquired start value is larger than the maximum value, correction is performed with the remainder value when the maximum value is divided by the start value as the start value. Thereafter, the start value is taken into the work area 608b8 (step S125), and in the next step S126, the start value setting bit of the soft random number status register 608b15 is set to OFF and the value of the start value setting register 608b5 is set. After that, the one-round completion notification register 608b6 is set to ON (step S127).

  Therefore, each time the start value setting register 608b5 and steps S122 to S125 set the initial rotation value of the first round in the random number counter, the random number counter is updated and the random number counter reaches the initial rotation value. It will function as a second stirring means for setting a new initial rotation value of the counter. Thus, since the initial value of the circulation of the random number counter is replaced with the initial value of the rotation set by the second agitator at least once, it is difficult to determine the value of the random number counter from the outside, and fraudulent acts are prevented. Can be prevented.

  Next, according to the sign B, it is determined whether or not the value of the number counter 608b13 has reached a specified value in step S147 which has shifted from step S127. Here, the specified value (specified update time) is, for example, the specified value is “2” in the “counter mode”, the specified value is in the “random number mode”, and the maximum value is “17” or more. In the case of “20” and “random number mode” and the maximum value is “16” or less, the specified value is set to “200”. Data of these specified values (specified update times) is stored in advance in the ROM 111B of the gaming microcomputer 111.

  Therefore, when updating of the random number counter 608b7 is started, the random number is not updated every time the divided signal is input from the frequency dividing circuit 609b to the random number update controller 608a, but until the input divided signal is detected a predetermined number of times. Will not update the random number counter 608b7, and the number of detections will be fixed to a certain number. In other words, in the “counter mode”, in order to update the random number counter 608b7, it takes time for the frequency-divided signal to be generated twice (specified update time). In the case of the “random number mode”, when the maximum value of the random number counter is “17” or more, it takes time to generate the divided signal 20 times in order to update the random number counter 608b7. In the case of the “random number mode”, when the maximum value of the random number counter is “16” or less, it takes time to generate the divided signal 200 times in order to update the random number counter 608b7.

  In the determination of whether or not the value of the number counter 608b13 has reached the specified value (step S147), if the value of the number counter has not reached the specified value (No), the process waits for a frequency division signal (step S150). The counter value is incremented (+1) (step S151), and the process returns to step S147. On the other hand, if it is determined whether or not the value of the number counter reaches the specified value (step S147), if the value of the number counter reaches the specified value (Yes), the value of the work area 608b8 is set in the random number counter 608b7. Then (step S148), the random number update informing register 608b9 is set to OFF (step S149), and the process returns to step S107 in FIG.

  Further, in determining whether the mode set in the maximum value setting register 608b4 is the “random number mode” or the “counter mode” (step S114), the mode set in the maximum value setting register 608b4 is the “random number mode”. In this case, the process proceeds to step S128. Then, the M-sequence random number is updated in the work area 608b8 (step S128), and it is determined whether or not the value based on the M-sequence random number in the work area 608b8 is larger than the maximum value (step S129).

  In this determination (step S129), when the value based on the M-sequence random number in the work area 608b8 is larger than the maximum value (Yes), it is determined whether or not a frequency-divided signal is detected (step S130). If a frequency-divided signal is detected in this determination (step S130) (Yes), the value of the number counter 608b13 is incremented by 1 (step S131), and the process returns to step S124. On the other hand, in the determination of whether or not the frequency-divided signal has been detected (step S130), when the frequency-divided signal has not been detected (No), the process returns to step S128.

If it is determined in step S129 that the value based on the M-sequence random number in the work area 608b8 is not larger than the maximum value (No), the process proceeds to step S132, and the tap value set in the tap setting register 608b2 next time. It is determined whether the tap setting bit of the soft random number status register 608b15 indicating whether (index) is stored is off (step S132). If the tap setting bit is not turned off, that is, if a new tap value is not stored (No), the process jumps to step S135.
If it is determined in step S132 that the tap setting bit is off (Yes), the process proceeds to step S133, and the tap value set in the tap setting register 608b2 matches the previous tap value. Determine whether or not. If the tap value matches the previous value (Yes), the process jumps to step S135. If it is determined in step S133 that the tap value does not match the previous value (No), the tap setting bit is turned on in the next step S134, and the process proceeds to step S135.

  In step S135, it is determined whether or not the start setting bit of the soft random number status register 608b15 is turned off. If the start value setting bit is not turned off (No), the process jumps to step S138. If it is determined in step S135 that the start value setting bit is off (Yes), the initial value counter value stored in the work area 608b8 and the start value setting register 608b5 are set in the next step S136. The start value that has been set is compared to determine whether or not it matches the previous value. If they match (Yes), the process jumps to step S138. If it is determined that they do not match (No) in step S136, the flag of the soft random number status register 608b15 is set to ON in the next step S137. Then, the process proceeds to step S138.

  In step S138, the value of the circulation counter 608b12 is incremented (+1 update), and it is determined whether or not the value of the circulation counter is equal to or greater than the maximum value (step S139). In this determination (step S139), when the value of the circulation counter is equal to or greater than the maximum value (Yes), the value of the circulation counter is set to “0” (step S140). On the other hand, when it is determined whether or not the value of the circulation counter is equal to or greater than the maximum value (step S139), if the value of the circulation counter is not equal to or greater than the maximum value (No), the process proceeds to step S147. Therefore, step S139 functions as a round detection means.

Next, the start value setting register 608b5 acquires the start value and corrects it to be equal to or less than the maximum value (step S141). Specifically, at this time, when the acquired start value is larger than the maximum value, correction is performed using the remainder value when the maximum value is divided by the start value as the start value. Thereafter, a characteristic polynomial (random number calculation formula) corresponding to the tap value set in the tap setting register 608b2 is set (step S142), and the tap setting bit of the soft random number status register 608b15 is set to OFF (step S143).
Subsequently, the start value is taken into the work area 608b8 (step S144), and in the next step S145, the start setting bit of the soft random number status register 608b15 is set to OFF and the process proceeds to step S146. In step S146, the one-round completion notification register 608b6 is set to ON, and the process proceeds to step S147 to determine whether or not the number counter is a specified value. In this determination, if it is determined that the value of the number counter 608b13 has reached the specified value (Yes), as described above, the value of the work area 608b8 is set in the random number counter 608b7 (step S148), and the random number update is performed. The middle notification register 608b9 is set to OFF (step S149), and the process returns to step S107 in FIG.

  Although not shown in FIG. 50 and FIG. 51, the random number update controller 608a checks the value of the random number counter 608b7 after the random number update process, and determines that it is an update error if it has not been updated. The update error notification register 608b10 is configured to set a value indicating that an error has occurred.

FIG. 52 shows an example of a specific procedure of the random number counter initial value correction process performed in step S160 of FIG.
In this random number counter initial value correction process, it is first determined whether or not the value of the initial value counter in the work area 608b8 is larger than the maximum value (step S161). This maximum value is a value set in the maximum value setting register 608b4. If it is determined in step S161 that the value of the initial value counter in the work area 608b8 is not larger than the maximum value (No), the process proceeds to step S163, and the value of the work area 608b8 is larger than the maximum value in step S161 (Yes). ), In step S162, the value of the random number counter in the work area 608b8 is corrected to be equal to or less than the maximum value, and then the process proceeds to step S163.
Specifically, a value obtained by calculating and correcting a remainder obtained by dividing the value of the random number counter in the work area 608b8 by the maximum value is used. Therefore, when the generated random value is set to a value outside the update range defined in the update range information, the value outside the update range is stored in the range information storage means in steps S161 to S162. The calculated remainder value functions as a first agitation means for setting the remainder value calculated as the initial rotation value for the first round of the random number counter.

In step S163, the corrected (or uncorrected) value matches the previous initial value stored in the backup area of the work area 608b8 (the value of the initial value counter 608b14 stored when the power is turned off). If it is determined as NO or not (NO), the process proceeds to step S165, and the value of the work area 608b8 is stored in the random number counter 608b7.
If it is determined in step S163 that it matches the previous initial value (Yes), the initial value counter value in the work area 608b8 is updated in the M series in step S164, and then the process proceeds to step S165. The value of 608b8 is stored in the random number counter 608b7. As a result, it is possible to prevent the random number counter value from starting to be updated from the same initial value as the previous time and to prevent the player from acquiring an illegal jackpot random number. Note that the update in step S164 is not limited to the M-sequence update, and may be an update by another method.

Although an inappropriate value (a value outside the predetermined range) may be stored as the cyclic initial value of the random number counter that is periodically updated by the user program, an inappropriate value (a value outside the predetermined range) is stored. If stored, it is corrected by the initial value correction process of the random number counter and set to a value within a predetermined range, and the initial value of the circulation of the random number counter is always an appropriate value within the predetermined range. Therefore, the game determination process can be performed with a predetermined correct probability.
In the above embodiment, the characteristic polynomial for generating a random number used for selecting the variation pattern as the effect mode of the variation display game is reset every time the generated random number makes a round. The characteristic polynomial may be reset every round, every three rounds, or every predetermined period. Further, in this embodiment, the case where the present invention is applied to the random number generation process for determining the variation pattern of the variation display game has been described. However, the present invention is also applicable to the random number generation processing for determining the off symbol of the variation display game. Can do.

From the above description, in the above embodiment, the variation display is based on the game control means for controlling the execution of the variation display game and the effect control command for instructing the effect of the variation display game supplied from the game control means. A gaming machine comprising: production control means for controlling the production of a game; and random number generation means for generating random values used in the control by the game control means,
The random number generation means includes a random value storage means for storing and holding the random value, a range information storage means for storing update range information for defining an update range of the random value, and a calculation according to a predetermined characteristic polynomial. Update means for updating the random number value, and when the updated random number value is outside the update range, repeatedly updating the random number value until the updated random value becomes a value within the update range, and a predetermined condition A polynomial setting unit that selects one characteristic polynomial from among a plurality of different characteristic polynomials and sets it as a new characteristic polynomial used by the updating unit,
The game control means includes an acquisition condition detection means for detecting that a predetermined random number acquisition condition has occurred, and the random value storage means when the acquisition condition detection means detects the occurrence of the predetermined random number acquisition condition. Random value acquisition means for acquiring a random number value from, and an effect mode used for the effect of the variable display game from among a plurality of effect modes prepared in advance based on the random value acquired by the random value acquisition means It can be understood that the invention includes an effect control command determining unit that selects and determines an effect control command corresponding to the selected effect mode.

  Next, the relationship between the tap value set in the tap setting register 608b2 and the characteristic polynomial pattern used in the M-sequence random number generation process executed in each of the random number blocks 608b to 609g and a specific example of the characteristic polynomial will be described. .

In the random number generation circuit 608 of this embodiment, the characteristic polynomial used for random number generation in each of the random number blocks 608b to 609g in the random number mode is one of eight patterns 0 to 7 as shown in FIG. The characteristic polynomial of which pattern is used to generate a random number is determined by the tap setting value of the tap setting register 608b2. That is, the characteristic polynomial pattern is designated using the tap setting value as an index. For example, when the tap setting value is “0”, the characteristic polynomial of pattern 0, that is, X ¹² + X ¹¹ + X ¹⁰ + X ⁴ +1 is selected.

  FIG. 53B shows the calculation of the characteristic polynomial of pattern 0 as a logic circuit. As shown in the figure, the characteristic polynomial used in the random number generation circuit 608 of this embodiment is a 12-bit shift register and a signal from the most significant bit is fed back to an arbitrary bit position to perform exclusive OR. It is composed of exclusive OR gates Ex-OR 1 to 3 for shifting the signal taken. That is, the logic circuit that implements the characteristic polynomial used in this embodiment has a configuration similar to hardware called a linear feedback shift register.

  In the logic circuit that performs the operation of the characteristic polynomial of pattern 0 shown in FIG. 53 (B), the exclusive OR gate includes bits R4 and R5, bits R9 and R10, and bits R10. And bit R11. When a characteristic polynomial of another pattern is selected, at least one of the three exclusive OR gates is located between bits different from those in FIG. A logic using an exclusive NOR gate instead of the exclusive OR gate is also possible.

FIG. 54 shows a procedure of M-sequence update processing (M-sequence random number generation processing) executed by the update controller 608a of the random number generation circuit 608 when the characteristic polynomial of pattern 0 is selected.
In the M-sequence update process when the characteristic polynomial of pattern 0 is selected, first, the 12-bit value of the random number counter (RAND) is acquired, and all bits are shifted one bit at a time to the upper side (step S191). . Next, the value of the most significant bit 11 overflowed by shifting is acquired (step S192), and an exclusive OR of the bit 11 and the value of bit 10 shifted in step S191 is calculated (step S193). Then, the calculated result is substituted into bit 11 (step S194).

  Next, an exclusive OR of the values of bit 11 and bit 9 shifted in step S191 is calculated (step S195), and the result is substituted into bit 10 (step S196). Further, an exclusive OR of the values of bit 11 and bit 3 shifted in step S191 is calculated (step S197), and the result is substituted into bit 4 (step S199). Thereafter, bit 11 shifted in step S191 is substituted for bit 0, and one random number update process is completed. The random number update controller 608a executes the above process every time the clock φ1 is input from the clock generator 609. When the generated random number makes a round, the tap value in the tap setting register is updated, the characteristic polynomial is changed, and the random number is generated.

In this embodiment, in addition to the generation of random random numbers by each characteristic polynomial, the tap value of the tap setting register is updated at random, so that it is possible to avoid the appearance of offset random numbers, that is, offset special pattern fluctuation patterns. Can do.
The update controller 608a includes a ROM for storing the control sequence (microprogram) and the table data of FIG. 53A, an instruction decoder for decoding the instruction code of the microprogram, a program counter for reading the next instruction code, and a bit shift Are provided, a logical operation such as exclusive OR, an arithmetic unit for performing addition and subtraction, and the like, so that the update controller 608a can execute the random number generation processing as described above. In other words, the update controller 608a itself is configured to have an architecture similar to that of an MPU (microprocessor) or DSP (digital signal processor).

Next, a second embodiment of the present invention will be described with reference to FIGS.
In the second embodiment, the CPU 311 of the effect control device 300 performs the random number generation processing for selecting the variation pattern, which was performed by the random number generation circuit 608 in the CPU of the game control device 100 in the first embodiment. It is a thing.
FIG. 55 (A) shows the procedure of main processing executed by the main control microcomputer (1st CPU) 311 of the effect control device 300.

  This main process is started when the power is turned on. First, initialization processing (step P1) for initializing the CPU is executed, then processing for initializing the VDP (graphic processor) 313 (step P2), and the LED control circuit 332 , 333 (step P3), a process for initializing the scaler 313b for enlarging and reducing the image in the VDP 313 (step P4), and a process for initializing the tone generator LSI 314 for controlling the sound output (step P4) Step P5), a process for initializing the motor control circuits 334 and 335 (Step P6), and a process for initializing drawing-related circuits such as the video RAM 313a in the VDP 313 (Step P7) are sequentially performed.

  Thereafter, screen drawing of the display device 41 by the VDP 313 is prohibited (step P8), and it is determined whether or not the motor control circuit is performing an initialization operation (step P9). Specifically, by monitoring a signal from a photo interrupter or the like that detects the initial position of the gear provided on the rotating shaft of the motor and detecting whether or not the motor is at a predetermined rotation angle, It is determined whether or not an initialization operation for moving the movable member of the apparatus to the initial position is in progress. If it is determined in step P9 that the initialization operation is being performed (Yes), the process returns to step P8 to prohibit screen drawing. As a result, the screen of the display device 41 remains in an erased state, so that if an accessory device has a failure and the movable member has not been moved to the initial position, the attendant at the amusement store can easily recognize the abnormality. it can.

  On the other hand, if it is determined in step P9 that the initialization operation is not in progress (No), the process proceeds to step P10 and screen drawing of the display device 41 by the VDP 313 is permitted. Thereafter, the base game process P11 (FIG. 55B), the random number generation process P12 (FIG. 56A), and the LED lighting process for turning on the LED to be lit from the initial state (before the game is started) (step P13). I do. After the LED lighting process in step P13, the process returns to the normal game process in step P11, and a loop process for repeating the above operation is performed. Note that the order of the normal game process in step P11 and the random number generation process in step P12 may be reversed.

FIG. 55B shows a detailed procedure of the normal game process in step P11.
In this normal game process, a power-on check process P111 for checking whether the power is turned on, a received command check process P112 for checking whether a command is received from the game control apparatus 100, or the display device 41 is displayed first. An initial screen display setting process P113 for setting an initial screen, an effect pattern determination process P114 (FIG. 56B) for determining a display mode (effect pattern) on the screen of the display device 41, and a customer on the screen of the display device 41. A customer waiting demo process P115 for displaying a waiting demo and a BGM fade-out process P116 for gradually lowering the music (BGM) being started up are performed.

FIG. 56 (A) shows a detailed procedure of the random number generation process in step P12 of FIG. 55 (A).
In this random number generation process, 16 types of characteristic polynomials (referred to as RAND0 to RAND15) similar to the M-sequence random number generation process using the characteristic polynomial described with reference to FIG. 53 are prepared, and random numbers generated by all the polynomials RAND0 to RAND15 are prepared. The generation process is executed step by step in order to generate 16 random numbers on the RAM. Therefore, each of the random number generation processing by the characteristic polynomials RAND0 to RAND15 functions as a random number generation means for determining the production mode. In addition, the entire random number generation process in FIG. 56A functions as an effect control random number generation unit that generates a random value used in the control by the effect control unit.

  In the first embodiment, a 12-bit characteristic polynomial is used as the characteristic polynomial. In the second embodiment, a 16-bit characteristic polynomial is used. Therefore, the generated random number is represented by a maximum of 16 bits. FIG. 56B shows examples of 16 types of characteristic polynomials RAND0 to RAND15. Note that the characteristic polynomial in FIG. 56B is an example, and the present invention is not limited to this.

FIG. 57A shows a detailed procedure of the effect pattern determination process in step P114 of FIG. 55B.
In the effect pattern determination process, it is first determined whether or not the background image change timing has come (step P141). If it is determined that it is not the change timing (step P141: No), the process jumps to step P143. If it is determined in step P141 that the change timing is reached (step P141: Yes), the process proceeds to step P142 to perform background image display processing.

  In the next step P143, it is determined whether or not the change timing of the changing symbol has arrived. If it is determined that it is not the change timing (step P143: No), the process jumps to step P145. If it is determined in step P143 that it is a change timing (step P143: Yes), the process proceeds to step P144 to perform a display process of a changing symbol. Thereafter, in step P145, it is determined whether or not the change timing of the start memory hold display (including the hold number and the prefetch notice) has come. Here, if it is determined that it is not the change timing (step P145: No), step P146 is skipped, and the effect pattern determination process ends. If it is determined in step P145 that it is a change timing (step P145: Yes), a hold display process is performed in the next step P146, and the effect pattern determination process ends.

FIG. 57B shows a detailed procedure of the background display process in step P142 of FIG.
In the background display process, a counter that counts an index value INDEX for designating any one of 16 types of characteristic polynomials RAND0 to RAND15 executed in the random number generation process of FIG. Is updated (+1) (step P411). Next, it is determined whether or not the value of INDEX is equal to or lower than an upper limit value (“15” in this case) (step P412). If it is determined that the value is equal to or less than the upper limit (step P412: Yes), the process jumps to step P414. If it is determined in step P142 that the value is not less than or equal to the upper limit value (step P412: No), the process proceeds to step P413 to perform processing for saving an initial value (for example, “0”) in INDEX. As a result, the INDEX value is sequentially updated by +1 up to the upper limit value, and when it exceeds the upper limit value, it returns to “0” and is updated again by +1.

  In the next step P414, a random number value generated by the characteristic polynomial RANDi corresponding to the INDEX value i is acquired. Thereafter, in step P415, a background image to be displayed is determined based on the random number value, and a command signal for instructing display of the determined background image is transmitted to the 2nd CPU (see FIG. 4). The background display process ends. Therefore, Steps P411 and P414 function as an effect random number acquisition unit that acquires a random number value of a different random number generation unit from a plurality of random number generation units for each acquisition, and Step P415 determines an effect mode in the variable display game. It will function as an effect mode determining means for determining the mode. The command signal set in the transmission buffer in the background display process of FIG. 57B is configured to be sequentially transmitted to the 2nd CPU 312.

  Note that the fluctuation display process in step P144 and the hold display process in step P146 in FIG. 57A are also performed in the same procedure as the background display process shown in FIG. It is only necessary to replace “background display” in step P414 in FIG. 57B with “variable display” or “hold display”, respectively. Therefore, illustration and description of the flowcharts of the variable display process and the hold display process are omitted. Steps P411 and P414 in each flowchart also function as an effect random number acquisition unit, and step P415 functions as an effect mode determination unit in the variable display game.

FIG. 58A shows a procedure of random number generation processing executed by the CPU 311 of the effect control device 300 when the INDEX0 characteristic polynomial is selected from the characteristic polynomials of FIG. 56B. This process is almost the same as the M-sequence update process by the random number generation circuit described with reference to FIG.
In the random number generation process when the characteristic polynomial of INDEX0 is selected, first, the 16-bit value of the random number counter (RAND) is acquired, and all the bits are shifted to the upper side by one bit (step P291). Next, the value of the most significant bit 15 overflowed by shifting is acquired (step P292), and the exclusive OR of the bit 15 and the value of bit 14 shifted in step P291 is calculated (step P293). Then, the calculated result is substituted into bit 15 (step P294).

Next, an exclusive OR of the values of bit 15 and bit 11 shifted in step P291 is calculated (step P295), and the result is substituted into bit 12 (step P296). Further, an exclusive OR of the values of bit 15 and bit 9 shifted in step P291 is calculated (step P297), and the result is substituted into bit 10 (step P298). Thereafter, bit 15 shifted in step P291 is substituted for bit 0 (step P299), and one random number update process is completed. This update result remains in the RAM.
FIG. 58B shows a procedure of random number generation processing executed by the CPU 311 of the effect control device 300 when the characteristic polynomial of INDEX8 is selected from the characteristic polynomial of FIG. 56B. This process is almost the same as the random number generation process described with reference to FIG.

  FIG. 59A shows the operation of the characteristic polynomial RAND0 of FIG. 58A as a logic circuit. As shown in the figure, the characteristic polynomial used in this embodiment is a 16-bit shift register and a signal obtained by taking an exclusive OR by feeding back the signal from the most significant bit to an arbitrary bit position. It is composed of exclusive OR gates Ex-OR1 to Ex3 to be operated. In the logic circuit that performs the operation of the characteristic polynomial of pattern 0 shown in FIG. 59 (A), the exclusive OR gate includes bits R9 and R10, bits R11 and R12, and bits R14. And bit R15.

  FIG. 59 (B) shows the calculation of the characteristic polynomial RAND8 of FIG. 58 (B) as a logic circuit. As shown in FIG. 59, in the logic circuit that performs the operation of the characteristic polynomial of INDEX8 shown in FIG. 59 (B), the exclusive OR gate is between bit R7 and bit R8, bit R8 and bit R9, And between bit R10 and bit R11, respectively. When a characteristic polynomial of another pattern is selected, at least one of the three exclusive OR gates is located between bits different from those in FIGS. 59 (A) and (B). A logic using an exclusive NOR gate instead of the exclusive OR gate is also possible.

From the above description, in the above embodiment, the variation display is based on the game control means for controlling the execution of the variation display game and the effect control command for instructing the effect of the variation display game supplied from the game control means. A gaming machine comprising: production control means for controlling the production of a game; and random number generation means for generating random values used in the control by the game control means,
The random number generation means includes a random value storage means for storing and holding the random value, a range information storage means for storing update range information for defining an update range of the random value, and a calculation according to a predetermined characteristic polynomial. Update means for updating the random number value, and when the updated random number value is outside the update range, repeatedly updating the random number value until the updated random value becomes a value within the update range, and a predetermined condition A polynomial setting unit that selects one characteristic polynomial from among a plurality of different characteristic polynomials and sets it as a new characteristic polynomial used by the updating unit,
The game control means includes an acquisition condition detection means for detecting that a predetermined random number acquisition condition has occurred, and the random value storage means when the acquisition condition detection means detects the occurrence of the predetermined random number acquisition condition. Random value acquisition means for acquiring a random number value from, and an effect mode used for the effect of the variable display game from among a plurality of effect modes prepared in advance based on the random value acquired by the random value acquisition means It can be understood that the invention includes an effect control command determining unit that selects and determines an effect control command corresponding to the selected effect mode.

  FIG. 60 shows a modification of the second embodiment. In the second embodiment, the change display process in step P144 and the hold display process in step P146 in FIG. 57A are performed in the same procedure as the background display process in step P142 shown in FIG. 57B. In this modification, as shown in FIGS. 60 (A) to (C), different procedures are used. Among these, the flowchart of the background display process of FIG. 60 (A) is the same as the flowchart of FIG. 57 (B). On the other hand, the flowchart of the variable display process in FIG. 60B and the flowchart of the hold display process in FIG. 60C are slightly different from the flowchart of the background display process in FIG.

  Specifically, the flowchart of the variable display process in FIG. 60B includes a counter that counts an index value INDEX for designating any one of 16 types of characteristic polynomials RAND0 to RAND15. The process is the same up to the process of updating (+1) (step P421), the process of determining whether or not the INDEX value is less than or equal to the upper limit value (step P422), and the process of saving the initial value in INDEX (step P423). Thereafter, a process of determining whether or not the INDEX value matches the INDEX value of the background display process (step P424) is performed. If the INDEX value matches (step P424: Yes), the process returns to step P421 and again. The difference is that the value of INDEX is updated. The process of acquiring a random value corresponding to the INDEX value in step P425 and the process of determining a background image to be displayed based on the random value of step P426 are step P414 in the flowchart of the background display process in FIG. Same as P415.

  The flowchart of the hold display process in FIG. 60C is substantially the same as the flowchart of the fluctuation display process in FIG. The difference is that in step P433, it is determined whether or not the INDEX value matches the INDEX value in the background display process and the INDEX value in the fluctuation display process, and if they match (step P424: Yes). The difference is that the process returns to Step P421 to update the INDEX value again. By performing such processing, when the modification of FIG. 60 is applied, the characteristic polynomial used in the background display processing, the variation display processing, and the hold display processing can be made different in the same variation display game. . As a result, it is possible to avoid any regularity among the background display, the change display, and the hold display.

  FIG. 61 shows a third embodiment. In the second embodiment, the random number generation process P12 in the main process of FIG. 55A performs random number generation by all 16 types of characteristic polynomials every time as shown in FIG. 56A. In the third embodiment, as shown in FIG. 62, only one random number generation using one type of characteristic polynomial is performed in one process. Specifically, first, the value of INDEX in the RAM is acquired (step P121). Then, the value of the acquired INDEX is determined (step P122), and according to the value, any of random number generation processing P123a to 123p by 16 types of characteristic polynomials RAND0 to RAND15 is executed.

  Thereafter, after obtaining the update result (new random value) (step P124), the INDEX value is updated (step P125). Then, in the next step P126, it is determined whether or not the updated INDEX value is less than or equal to the upper limit value (here, “15”). If it is not less than or equal to the upper limit value (step P126: No), the process proceeds to step P127. The initial value is set in the advance INDEX and the random number generation process is terminated. On the other hand, when the updated INDEX value is less than or equal to the upper limit value (step P126: Yes), step P127 is skipped and the random number generation process ends. Therefore, the entire random number generation process of FIG. 60 functions as an effect control random number generation means for generating a random value used in the control by the effect control means. According to the third embodiment, since it is not necessary to generate random numbers using 16 types of characteristic polynomials every time, there is an advantage that the burden on the CPU 311 can be reduced as compared with the second embodiment.

  FIG. 62 shows a modification of the third embodiment. In this modification, as shown in the flowchart of FIG. 55A in the second and third embodiments, the random number generation process P12 performed as a process different from the normal game process P11 is changed to the process shown in FIG.

Is. Specifically, in the background display process, as shown in FIG. 62B, first, a random number generation process P12 as shown in FIG. 61 is executed. Thereafter, the updated random number is acquired (step P414), and the background display is determined based on the acquired random value (step P415).
