The pair of opening / closing members 37b, 37b of the normal variation winning device 37 always holds a closed state (a disadvantageous state for the player) with an interval of about the diameter of the game ball. However, since the start winning port 36 is provided above the normal variation winning device 37, the game ball cannot be won in the closed state.
When the result of the normal variation display game becomes a predetermined stop display mode, it is opened in a reverse “C” shape by a general electric solenoid 37c (see FIG. 3) as a driving device, and a normal variation prize is awarded. The device 37 can be changed to an open state (a state advantageous to the player) in which a game ball easily flows.

   Further, a special variable winning device (large winning mouth) 38 that can be converted into a state where a game ball is not accepted and a state where it is easy to accept depending on the result of the special figure changing display game is arranged below the normal variable winning device 37. Yes.

The special variation winning device 38 has an attacker-type open / close door 38c that can be opened by rotating in a direction in which the upper end side is tilted toward the near side, depending on the result of the special figure variation display game as an auxiliary game. The state is converted from a closed state (closed state unfavorable for the player) to an open state (a state advantageous to the player).
That is, the special variable winning device 38 includes a large winning opening that is opened and closed by an open / close door 38c that is driven by a large winning port solenoid 38b (see FIG. 3) as a driving device. By converting the closed state from the closed state to the open state, the inflow of game balls into the special winning opening is facilitated, and a predetermined game value (prize ball) is given to the player.

In addition, a count switch 38a (see FIG. 3) as a detecting means for detecting a game ball that has entered the special winning opening is disposed inside the special winning opening (winning area).
Below the special variable winning device 38, there is provided an out port 39 for collecting game balls that have not won a winning port.

   Also, outside the game area 32 (for example, at the top of the game board 30), the first special figure fluctuation display game and the second special figure fluctuation display game that form the special figure fluctuation display game, and the winning for the normal figure start gate 34 are awarded. A collective display device 50 is provided for executing a universal map display game with a trigger at one location.

   The collective display device 50 includes a first special figure fluctuation display unit (special figure 1 display) and a second special figure fluctuation for a first special figure fluctuation display game configured by a 7-segment display (LED lamp) or the like. The second special figure fluctuation display section (special figure 2 display) for the display game, the fluctuation display section (general figure display) for the common figure fluctuation display game, and each fluctuation display game which is also composed of LED lamps. A memory display unit for informing the start memory number is provided. In addition, the collective display device 50 is provided with a display unit for notifying the game state, an error display unit for displaying an error, and a round display unit for displaying the number of rounds at the time of the big hit (the number of opening / closing of the special variable winning device 38). Yes.

The special figure fluctuation display game in the special figure 1 display and the special figure 2 display is, for example, while the fluctuation display game is being executed, that is, while the decoration special figure fluctuation display game is being performed on the display device 41, Display blinking drive to indicate that it is changing. When the result of the game is “out of”, for example, the central segment is turned on as a result mode of out of game, and when the result of the game is “win”, the result of out of game (special result mode) is not. A game result is displayed with a result mode other than the result mode (for example, a number such as “3” or “7”) turned on.

   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 change 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. When a game ball wins the general winning opening 35, the start winning opening 36, the normal variation winning apparatus 37, or the special variable winning apparatus 38, the number of winning balls corresponding to the type of the winning opening is awarded by the payout control apparatus 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 variation display game is executed by a variation display unit (common diagram display) provided in the collective display device 50. This figure display unit is composed of LEDs that indicate hits in the lit state as normal identification information (common charts, normal symbols), and LEDs that indicate deviation 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, and is stored up to a predetermined upper limit number (for example, 4), and also to the normal variable winning device 37. The winning game ball is detected as the start winning ball of the second special figure variation display game, and stored up to a predetermined upper limit number (for example, four).

   In addition, when the starting winning ball is detected, 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 memory 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 chart start memory is displayed on the memory display section for notifying the start winning number of the collective display device 50 and also displayed on the display device 41 of the center case 40.

The game control device 100 is configured to display a special figure 1 display or a special figure 2 display (variation) provided in the collective display device 50 based on a winning at the start winning opening 36 or the normal variation winning award device 37, or their start memory. The first or second special figure variation display game is played on the display device.
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 variation display game, when the display form of the special figure 1 display or the special figure 2 display becomes a special result form, it becomes a big hit and a special game state (so-called big hit state). Become. 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.

   Note that the special figure 1 display and the special figure 2 display may be separate displays or the same display, but each special figure variation display game is not to be executed independently or simultaneously. 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. Further, the special game variable display game may be executed only by the display device 41 without providing the game machine 10 with the special map 1 display and the special map 2 display.

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. If 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 the special game state or in the 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.

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 including an input port, an output unit 130 including an output port and a driver, and the like.

   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 is 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, the 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 by the second input port 122 is read 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 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. An error signal indicating that the control is not possible is supplied from the data bus 140 to the trial test apparatus via the buffer 134 and the relay board 70. The relay board 70 is provided with a port that takes in the signal output from the buffer 134 and supplies it to the test test apparatus, a connector that relays and transmits a signal line of a switch detection signal that does not pass through the buffer, and the like. ing. A chip enable signal CE output from the gaming microcomputer 111 is also supplied to the port on the relay board 70, and the signal of the port selected and controlled by the signal CE is supplied to the test firing test apparatus.

   In addition, the output unit 130 is connected to the data bus 140 and is connected to the data bus 140 to open a special variation winning device 38 (a large winning opening solenoid) 38b and a solenoid (normal electric solenoid) 37c to open a movable member 37b of the normal variation winning device 37. The third output port 135 for outputting the opening / closing data of the LED and the ON / OFF data of the digit line to which the cathode terminal of the LED of the collective display device 50 is connected. A fourth output port 136 for outputting ON / OFF data of the segment line connected to the anode terminal, and a fifth output port 137 for outputting information related to the gaming machine 10 such as jackpot information to the external information terminal 71 are provided. It has been. Information relating to the gaming machine 10 output from the external information terminal 71 is supplied to, for example, an information collection terminal installed in a game store or a game hall internal management device (not shown).

   Further, the output unit 130 receives the opening / closing data signal of the big prize opening solenoid 38b output from the third output port 135, and receives the solenoid driving signal and the opening / closing data signal of the power solenoid 37c to generate the solenoid driving signal. A first driver (drive circuit) 138a for outputting, a second driver 138b for outputting an on / off drive signal for a digit line on the current drawing side of the collective display device 50 outputted from the third output port 135, and a fourth output port 136 The external information signal supplied to the external device such as the management device from the third driver 138c and the fifth output port 137 for outputting the ON / OFF drive signal of the segment line on the current supply side of the collective display device 50 output from the external information A fourth driver 138d for outputting to the terminal 71 is provided.

   The first driver 138a is supplied with DC32V from the power supply device 400 as a power supply voltage so that a solenoid operating at 32V can be driven. Also, DC12V is supplied to the third driver 138c that drives the segment lines of the collective display device 50. Since the second driver 138b for driving the digit line is for extracting the digit line corresponding to the display data with a current, the power supply voltage may be either 12V or 5V. A dynamic drive method is achieved by flowing current to the anode terminal of the LED through the segment line by the third driver 138c that outputs 12 V, and drawing the current from the cathode terminal through the segment line by the second driver 138b that outputs the ground potential. The power supply voltage flows through the LEDs sequentially selected in step 1 so that the LEDs are lit. The fourth driver 138d that outputs the external information signal to the external information terminal 71 is supplied with DC12V in order to give the external information signal a level of 12V. Note that the buffer 134, the third output port 135, the first driver 138a, and the like may be provided on the output board 130 of the game control device 100, that is, on the relay board 70 side instead of the main board.

   Further, the output unit 130 is provided with a photocoupler 139 for transmitting information such as an identification code and a program of each gaming machine to the external inspection device 500. The photocoupler 139 is configured to be capable of bi-directional communication so that the gaming microcomputer 111 can transmit and receive data to and from the inspection device 500 through serial communication. Note that such data transmission / reception is performed using a serial communication terminal of the gaming microcomputer 111 as in the case of a general general-purpose microprocessor, and therefore, ports such as the input ports 122 and 123 are not provided.

Next, game control performed in the game control apparatus 100 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 for determining whether or not the first special figure variation display game is missed is performed. Therefore, the CPU 111A functions as a random value acquisition condition detection unit and a random value acquisition unit.

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. A random number value is extracted and compared with a determination value stored in the ROM 111B, and a process of determining whether or not the second special figure variation display game is missed 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 or the special figure 2 display of the collective display device 50, a process for displaying a special figure fluctuation display game to stop display is performed. Therefore, the CPU 111A functions as a game result determination unit that determines a random number value and performs a determination process related to the game.

Further, the effect control device 300 performs a process of displaying a decoration special figure variation display game corresponding to the special figure variation display game on the display device 41 based on the control signal from the game control device 100.
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, when the result of the special figure variation display game is a win, the CPU 111A of the game control device 100 displays a special result mode on the special figure 1 display or the special figure 2 display and generates a special game state. I do.
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).
When the result of the special figure variation display game is out of control, control is performed to display the result form of the deviation on the special figure 1 display or the special figure 2 display.

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 game state after the special game state is ended 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-type 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 Thus, the number of times of opening 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.
As a result, the game ball can easily win the normal variation winning device 37, and the second special figure variation display game can be easily started.
In addition, the time variation operation state of the probability variation state, the normal variation display game, and the normal variation prize winning device 37 can be generated independently, and both can be generated at the same time, or only one can be generated. Is possible.

   Next, the configuration of the gaming microcomputer 111 that constitutes the gaming machine control system of FIG. 3 will be described with reference to FIG. FIG. 4 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 also 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.

   The information area 600B for managing information in the game processing device 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 means 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 game area 600A side is connected). 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. 5 is a block diagram showing details of the random number generation circuit 608 in the game arithmetic processing device 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. Based on the clock signal φ2 from the frequency dividing circuit 609b, a CTC (Counter / Timer Circuit) circuit 609a sends a timer interrupt signal (CTC1) with a predetermined period (for example, 2 milliseconds) to the CPU 601 and the random number controller 608a. A signal CTC2 is generated which gives a trigger for updating the supplied random number. 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 is used to generate a jackpot random number (special figure), the second random number block 608c is used to generate a hit random number (common figure), and the third random number block 608d is a jackpot symbol random number 1. The fourth random number block 608e is used for generating the jackpot symbol random number 2, respectively.

   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 of the present embodiment is configured to input a signal CTC2 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 above 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 for notifying the CPU 601 of the occurrence of an abnormality (error) when random number update abnormality is detected by the random number update controller 608 a, random number circuit reset register 608b11, a circulation counter 608b12 that counts the number of rotations of the random number counter 608b7, a frequency counter 608b13 that counts the number of times the divided signal φ1 is input, power-on (system reset) The included) for an initial value to generate a different value for each counter 608B14, constituted by such software random number status register 608b15 as setting information storage means for indicating the update status of the register in the random number generation circuit or the like.

   The update error notification register 608b10 is provided for each random number block 608b to 608g in this embodiment, but may be a common update abnormality notification register. In that case, the update abnormality notification register may be composed of 6 bits, and each bit may correspond to the random number blocks 608b to 608g, and the update abnormality of each block may be stored in an identifiable manner.

   Among the above registers, the work area (update means) 608b8 and the initial value counter 608b14 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. If the tap setting register 608b2 has not been set, the user program accesses on condition that the random number update controller 608a allows access. 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. If it is set to “permitted”, the signal CTC2 from the CTC circuit 609a is used as a trigger for the random number counter 608b7. 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, “0” is stored in the tap setting register 608b2.
When a value other than "" is written, the random number counter 608b7 is activated. 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 maximum value setting register 608b4 may set the update range in units of bits instead of setting the maximum value.

   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, and 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 RAM or non-volatile memory backed up by a backup power source, and functions as an update buffer and backup area for the random number counter 608b7. The work area 608b8 is updated by updating random numbers. The stored 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, and a random number update error occurs when the CPU 601 reads the value of this register. It is possible to know whether or not. Accordingly, the update error notification register 608b10 functions as update abnormality information storage means for storing update abnormality information indicating that an abnormality has occurred in the random number value update in 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. In this embodiment, the update error notification register 608b10 is configured such that a common flag is set by an update abnormality detection process provided corresponding to each of the random number mode and the counter mode. However, the present invention is not limited to this, and a separate flag may be set by update abnormality detection processing in the random number mode and the counter mode.

   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. 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.

   Next, a control procedure in the random number generation circuit 608 by the random number update controller 608a will be described. FIG. 6 shows a flowchart of the first half of the main processing by the random number update controller, and FIG. 7 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 on. The process by the random number update controller 608a includes the clock generator 609 in addition to the main process. 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. 6 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 S100). 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 S101). Subsequently, the change of the random number counter 608b7 by the user program is permitted (step S102), and the setting of the tap setting register 608b2 is awaited (step S103). 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 S101 function as a 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 rotation value of the first round of the random number counter. Become.

   Thereafter, the random number update controller 608a prohibits the change of the random number counter 608b7 (step S104), stores the value of the random number counter 608b7 at this time in the work area 608b8 (step S105), and the value of the random number counter set by the user After executing random number counter initial value correction processing (step S106) 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. 4). 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.

   In the random number counter initial value correction process S106, it is determined whether or not the value of the initial value counter in the work area 608b8 is larger than the maximum value set in the maximum value setting register 608b4, and the value of the work area 608b8 is the maximum value. If it is determined that the value is larger than (Yes), the value of the random number counter in the work area 608b8 is corrected to be equal to or less than the maximum value. 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. Then, the corrected value (or the uncorrected value if smaller than the maximum value) is the previous initial value stored in the backup area of the work area 608b8 (the initial value counter 608b14 stored at the time of power-off). It is determined whether or not it matches (value), and if it does not match (No), the value of the swork area 608b8 is stored in the random number counter 608b7.

If it is determined that the value after correction (or the value not corrected when it is smaller than the maximum value) matches the previous initial value (Yes), the value of the initial value counter in the work area 608b8 is determined. After updating the M series, the value of the work area 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.
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. When stored, the correction by the initial value correction process of the random number counter is performed, the value is reset 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. Since the value is set, the game determination process can be performed with a predetermined correct probability.

After setting the number counter 608b13 to “0” in step S107 in FIG. 6, 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 the process proceeds to the next step S160 to execute counter mode update abnormality monitoring processing. Accordingly, the random number update controller 608a functions as an update abnormality detection unit. The counter mode update abnormality monitoring process in step S160 will be described in detail later with reference to FIG.
Thereafter, it is determined whether or not the value of the circulation counter is equal to or greater than a value obtained by adding one 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 greater 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 greater 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. 7 (symbol B).

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). When the range of the initial value random number counter is larger than that of the hit random number counter, a case is considered in which a value that cannot be taken by the hit random number counter is acquired and set as a start value from the initial value random number counter.
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 updating notification 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 according to symbol A. 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 status register 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 in step S136 that they do not match (No), the status register flag is set to ON in the next step S137, and step S138 is executed. Proceed to

   In step S138, the value of the circulation counter 608b12 is incremented (+1 updated). Thereafter, after executing the random number mode update abnormality monitoring process (S160 '), 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. The random number mode update abnormality monitoring process (S160 ') is similar to the counter mode update abnormality monitoring process (details are shown in FIG. 8) in step S160 of FIG.

   After setting the value of the circulation counter to “0” in step S140, 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), the start setting bit of the status register is set to OFF in the next step S145, 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.

FIG. 8 shows an example of a specific procedure of the counter mode update abnormality monitoring process performed in step S160 of FIG.
In the counter mode update abnormality monitoring process, it is first determined whether or not the random value in the work area 608b8 matches the previous value (step S161). If it is determined that they match (Yes), the process proceeds to step S167 to turn on the flag of the update error notification register 608b10, and then whether or not the flag of the random number circuit reset register 608b11 is turned on by the CPU 601. Determination is made (step S168). If it is not turned on, it waits until it is turned on by repeatedly executing step S168, and if it is determined that the flag of the random number circuit reset register 608b11 is turned on (step S168: Yes), according to symbol D, FIG. Returning to step S100 of the flowchart of FIG. This is because if the normal update is executed, the random value in the work area 608b8 will not match the previous value. Even when the power is shut off and turned on again in the standby state in step S168, the process returns to S100 by the power-on reset and the processing is sequentially performed.

   On the other hand, if it is determined in step S161 that the random number value does not match the previous value (No), the process proceeds to step S162, and it is determined whether or not the value of the circulation counter 608b12 is greater than “maximum value + 1”. Is done. If it is determined that the flag is large (Yes), the process proceeds to step S167, the flag of the update error notification register 608b10 is turned on, and then it is determined whether the flag of the random number circuit reset register 608b11 is turned on (step S168). ). If it is not turned on, the process waits until it is turned on by repeatedly executing step S168. If it is determined that the flag of the random number circuit reset register 608b11 is turned on (Yes), the process returns to step S100 and the initialization process is started. Try again. This is because the range of the random number update is defined by the set value of the maximum value setting register 608b4, and if the normal update is executed, the value of the circulation counter 608b12 does not become larger than “maximum value + 1”.

   If it is determined in step S162 that the value of the circulation counter 608b12 is smaller than “maximum value + 1” (No), the process proceeds to step S163 to determine whether or not the value of the work area 608b8 is “start value”. Is called. If it is determined that the value of the work area 608b8 is the “start value” (Yes), it is determined in step S164 whether the value of the circulation counter 608b12 is “maximum value + 1”. If it is determined that the value of the circulation counter 608b12 is not “maximum value + 1” (No), the process proceeds to step S167, the flag of the update error notification register 608b10 is turned on, and the flag of the random number circuit reset register 608b11 is set. It is determined whether or not it is turned on (step S168). If it is not turned on, the process waits until it is turned on by repeatedly executing step S168. If it is determined that the flag of the random number circuit reset register 608b11 is turned on (Yes), the process returns to step S100 and the initialization process is started. Try again.

   If the normal update process is executed, if the value of the lap counter 608b12 becomes “maximum value + 1”, the “start value” is set to the value of the work area 608b8 (see step S125). The reason why the value of the circulation counter 608b12 is not “maximum value + 1” even though the value of the area 608b8 is “start value” is that the “start value” is set in the work area 608b8 by mistake or illegally. Because. If it is determined in step S164 that the value of the circulation counter 608b12 is “maximum value + 1” (Yes), the process proceeds to step S165. If it is determined in step S163 that the value of the work area 608b8 is not the “start value” (No), step S164 is skipped and the process proceeds to step S165.

   In step S165, it is determined whether or not the value of the circulation counter 608b12 is “maximum value + 1”. If it is determined that the value of the circulation counter 608b12 is “maximum value + 1” (Yes), the process proceeds to step S166. It is determined whether or not the value of area 608b8 is the “start value”. Here, when it is determined that the value of the work area 608b8 is the “start value” (step S166: Yes), the update abnormality monitoring process is exited. On the other hand, if it is determined in step S166 that the value of the work area 608b8 is not the “start value” (No), the process proceeds to step S167 to turn on the flag of the update error notification register 608b10 and then the random number circuit reset register 608b11. It is determined whether the flag is turned on (step S168). If it is not turned on, the process waits until it is turned on by repeatedly executing step S168. If it is determined that the flag of the random number circuit reset register 608b11 is turned on (Yes), the process returns to step S100 and the initialization process is started. Try again.

If the normal updating process is executed, if the value of the circulation counter 608b12 becomes “maximum value + 1”, the “start value” is set as the value of the work area 608b8 (see step S125). Although the value of the counter 608b12 is “maximum value + 1”, the value of the work area 608b8 is not the “start value” even if the value of the circulation counter 608b12 becomes “maximum value + 1” due to malfunction. This is because it is considered that the “start value” is not set in 608b8. If it is determined in step S165 that the value of the circulation counter 608b12 is not “maximum value + 1” (No), step S166 is skipped and the update abnormality monitoring process is exited.

   The specific procedure of the random number mode update abnormality monitoring process performed in step S160 'of FIG. 7 is substantially the same as the specific procedure of the counter mode update abnormality monitoring process shown in FIG. The only difference from the counter mode update abnormality monitoring process is that “maximum value + 1” becomes “maximum value” in steps S162, S164, and S165. As shown in FIG. 7, in the update process in the random number mode, when the value of the circulation counter 608b12 becomes the “maximum value”, the “start value” is set to the value of the work area 608b8 ( Steps S139 to S144).

Next, the control executed by the game microcomputer (game microcomputer) 111 of the game control device 100 incorporating the random number generation circuit will be described.
The control process by the gaming microcomputer 111 includes a main process (mainly see FIGS. 9 and 10) 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. 13).

[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 rises first and sends the command to the payout control device 200 before the payout control device 200 starts up, thereby avoiding the payout control device 200 from 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).
Also, 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 has not been restored (step S11; No), and if the checksum is not normal in step S13 ( If it is determined as step 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 flag is set in the collective display device 50 after the high probability notification flag is set in step S17. 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 special game big hits (big hit random numbers)). The initial value (start value) of the random numbers that determine the winning symbols for the big hit (big hit symbol random number 1, the big hit symbol random number 2), and the random numbers that determine the hit of the regular game (hit random number) are saved in a predetermined area of the RWM. After that, the interruption is permitted (step S26). The jackpot symbol random number is a random number relating to the determination of the number of rounds in the special game state, the number of short times given after the end of the special game, and the probability variation state.

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, a random number error monitoring process (step S27) for monitoring an update error of the random number generation circuit, and an initial value random number update process (step S28) for updating various initial value random number values to break the regularity of the random numbers are performed. .

   After the initial value random number update process in step S28, 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 S29). If no power failure has occurred (step S29; No), the process returns to step S27, and the initial value random number update process to the power failure monitoring signal check (loop process) are repeated. By permitting an interrupt before the random number error monitoring process (step S27) (step S26), if a timer interrupt occurs during the random number error monitoring process and the initial value random number update process, the interrupt process is preferentially executed. Thus, it is possible to avoid the interruption of the interrupt process by waiting for the timer interrupt by the random number error monitoring process and the initial value random number update process.

   Further, unless a power failure or power interruption occurs, the loop of steps S27 to S29 is repeatedly executed, and during that time, processing by timer interrupt processing (FIG. 13) described later is periodically executed. Since the time required for each interrupt process is different each time, the number of iterations of the loop of steps S27 to S29 from one interrupt to the next interrupt is different each time, thereby generating the initial value random number update process. The initial value random number to be changed will be different each time.

   If it is determined in step S29 that a power failure has occurred (step S29; Yes), processing for temporarily prohibiting interruption (step S30) and processing for turning off all output ports (step S31) 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 S32) and the process of calculating the checksum when the RWM is turned off (step S33), access to the RWM is prohibited. After performing the process (step S34), 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.

[Random number error monitoring processing]
Next, details of the random number error monitoring process (step S27) in the main process described above will be described.
As shown in FIG. 11, in the random number error monitoring process, first, the value of the update error notification register 608b15 in the random number generation circuit 608 is read to check whether an update error has occurred (step S271). If it is determined that no update error has occurred (step S272; No), the random number error monitoring process is terminated without doing anything. On the other hand, if it is determined that an update error has occurred (step S272; Yes), a process of setting the update error flag provided in the RWM to ON (step S273), and turning on the initial value setting flag The setting process (step S274) is sequentially performed. The update error flag is referred to in the next initial value random number update process of FIG. 12, and the initial value setting flag is referred to in the random number update process 1 of FIG.
If an update error has occurred in step S272 (step S272; Yes), restart is performed by turning on the flag of the random number circuit reset register 608b11. If the update error is still not resolved, steps S273 and S274 are performed. May be executed. Further, when an update error occurs, an error display unit (LED) that displays an error of the collective display device 50 may be turned on.
Further, a random circuit error notification command may be transmitted. This command is a command transmitted to the production control device 300 (see FIG. 3). When this command is received, the production control device 300 displays, for example, an error occurrence on the display device 41. The display indicating the occurrence of the error only needs to be recognized by the store clerk of the game store. For example, it is desirable not to affect the game by displaying a predetermined symbol at a predetermined position (such as a corner) of the liquid crystal display. .

[Initial value random number update processing]
Next, details of the initial value random number update process (step S28) in the main process described above will be described.
As shown in FIG. 12, in the initial value random number update process, first, the update error flag in the RWM is read to check the state of the flag (update error flag) (step S281). If it is determined that the update error flag is not turned on (step S282; No), nothing is done and the process exits the random number error monitoring process. On the other hand, if it is determined that the update error flag is on (step S272; Yes), the process of incrementing (updating (+1)) the big hit random number of the special figure (step S283), the normal initial hit random number Is incremented (update (+1)) (step S284), jackpot symbol initial value random number 1 is incremented (update (+1)) (step S285), jackpot symbol initial value random number 2 is incremented (update (+1)) The processing (step S286) is sequentially performed.

   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. Therefore, the main processing by the CPU 111A of the gaming microcomputer 111 refers to the replacement counter updating means for updating the replacement counter that generates a value used as the initial value of the lap, and the update error notification register as the update abnormality information storage means. It functions as an abnormality determination unit that determines whether or not an abnormality has occurred in the update of the random number value in the random number generation circuit 608 as one random number generation unit.

   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. The jackpot random number is a random number common to the variable display games of FIG. 1 and FIG.

[Timer interrupt processing]
Next, timer interrupt processing will be described.
As shown in FIG. 13, 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 in FIG. 13 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 first 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 reading inputs from various sensors (start port 1 switch 36a, start port 2 switch 37a, gate switch 34a, count switch 38a, etc.), ie, 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.

[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 values (start values) of the jackpot random number, the hit random number, the jackpot symbol random number 1, 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. 4: 608) provided in the gaming microcomputer 111 is updated.

   As shown in FIG. 14, in the random number update process 1, first, the update error flag in the RWM is read to check the state of the flag (update error flag) (step S451). If it is determined that the update error flag is not turned on (step S452; No), the process exits the random number update process 1 without doing anything. On the other hand, when it is determined that the update error flag is on (step S452; Yes), the state of the initial value setting flag is confirmed (step S451). If it is determined that the initial value setting flag is not on (step S453; No), the process jumps to step S459.

   If it is determined that the initial value setting flag is on (step S453; Yes), the process proceeds to step S454, and the value of the big hit initial value random number updated in the initial value random number update process (FIG. 12) is set to RWM. Are saved in a predetermined area (a soft random number counter for big hits). Subsequently, the value of the hit initial value random number, the value of the big hit symbol initial value random number 1, and the value of the big hit symbol initial value random number 2 are sequentially saved in the corresponding areas in the RWM (steps S455, S456, S457). Then, the initial value setting flag is set to OFF (step S458), and the process proceeds to step S459. As described above, in the random number update process 1, when the update error flag is turned on, the initial value random numbers of various random numbers updated in the initial value random number update process in step S28 of FIG. 10 are saved once in the RWM. It will be. Here, an initial value random number updated by the random number generation circuit 608 may be used.

   In step S459, processing for reading and updating (+1) the jackpot random number in the RWM in which the value of the jackpot initial value random number was saved in the processing of step S454 is performed. Then, in the next step S460, it is determined whether or not the big hit random number has made a round, and if it is determined that the round has not been made (step S460: No), the update result is saved in the original location (step S461). If it is determined that the big hit random number has been completed (step S460: Yes), the process proceeds to step S462 to save the big hit initial value random number updated in the initial value random number update process (FIG. 12), and then goes to step S463. move on.

   In step S463, a process of reading and updating (+1) the hit random number in the RWM in which the value of the initial random number is saved in the process of step S455 is performed. Then, in the next step S464, it is determined whether or not the corresponding random number has been completed. If it is determined that the random number has not been completed (step S464: No), the update result is saved in the original location (step S465). If it is determined that the winning random number has been completed (step S464: Yes), the process proceeds to step S466 to save the value of the winning initial value random number updated in the initial value random number updating process (FIG. 12), and then to step S467. move on.

   In step S467, processing for reading and updating (+1) the jackpot symbol random number 1 in the RWM in which the value of the jackpot symbol initial value random number 1 is saved in the processing of step S456 is performed. Then, in the next step S468, it is determined whether or not the big hit symbol random number 1 has made a round. If it is determined that the round has not been made (step S468: No), the update result is saved in the original location (step S469). If it is determined that the big hit symbol random number 1 has been completed (step S468: Yes), the process proceeds to step S470 to save the value of the big hit symbol initial value random number 1 updated in the initial value random number update process (FIG. 12). The process proceeds to step S471.

   In step S471, processing for reading and updating (+1) the jackpot symbol random number 2 in the RWM in which the value of the jackpot symbol initial value random number 2 has been saved in the processing of step S457 is performed. Then, in the next step S472, it is determined whether or not the big hit symbol random number 2 has made a round, and if it is determined that the round has not been made (step S472: No), the update result is saved in the original location (step S473). Also, if it is determined that the big hit symbol random number 2 has made a complete cycle (step S472: Yes), the process proceeds to step S474 and the value of the big hit symbol initial value random number 2 updated in the initial value random number update process (FIG. 12) is saved. , Exit from the random number update process 1.

When the initial value setting flag is turned on in step S458, the random number update process 1 is started again at the next timer interruption, and even if it is determined in step S452 that the update error flag is turned on, the initial value setting step 1 is initialized in step S453. Since it is determined that the value setting flag is off and the process jumps to step S459, each random number is updated (+1) every time a timer interrupt occurs until each random number is completed.
Therefore, the interrupt processing of the CPU 111A is the second random number generation means for updating the random number value based on the time-up of the interrupt timer, and the random number counter update that circulates within the predetermined minimum value and maximum value range and updates the random number counter. Each time the means and the random number counter are updated to reach the initial circulation value, it functions as an agitation means for setting a new initial rotation value of the random number counter.

As described above, the update of the random number in the random number update process 1 is executed when the update error flag is turned on, while the random number generation circuit 608 is updating normally, as shown in FIG. This is because the random number updated by the random number update process 1 is loaded when the random number value of the random number generation circuit is loaded in A205 and an update error occurs. In addition, the presence of the random number update process 1 allows game control to be continuously executed without using the random number value of the random number generation circuit 608 when an update abnormality occurs in the random number generation circuit.
In the random number update process 1, since the initial value random number of various random numbers updated in the initial value random number update process in step S28 of FIG. 10 is updated as the start value, the start value of the random number counter can be made random. it can. This makes it difficult to determine the update timing of the random number counter in which a specific gaming state (big hit state) occurs, making it extremely difficult to perform fraudulent acts.
In addition, the update range of various random numbers updated in the random number update process 1 is the same range as the random number value updated in the random number generation circuit (in this embodiment, the maximum random number per map is set to 0 to 250, for example) Since the maximum value of the special figure big hit symbol random numbers 1 and 2 is updated, for example, from 0 to 200), it is not necessary to change the number of judgment values used when judging whether or not the big hit or the hit. A common determination process can be used before and when an abnormality occurs.
In addition, the random number update range is not limited as long as the lottery can be performed with the same probability before the occurrence of the abnormality and at the time of the occurrence of the abnormality. For example, the random number update range is 10 times and the number of determination values is 10 times. It may be.

   The random number update process 2 (step S46) in the timer interruption process of FIG. 13 is a process of updating the fluctuation pattern random numbers 1, 2, and 3 for determining the fluctuation pattern in the fluctuation display game of the special figures 1 and 2. In this embodiment, the update is performed by the user program without using the random number generation circuit (FIG. 4: 608), and thus the description thereof is omitted. However, it is also possible to update using random number blocks 608f, 608g, 608h, etc. in the random number generation circuit 608. In that case, it can be updated by the same method as the big hit random number described above. Also, the processing when an update error occurs in the random number generation circuit can be the same as described above. Further, the fluctuation pattern random numbers 1, 2, and 3 may be updated while updating the tap value set in the tap setting register 608b2 in the random number generation circuit 608.

[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. 15, 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. Details of the start port switch monitoring process (step A1) will be described later with reference to FIG.

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.
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.

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.
Furthermore, if the game processing number is “2” in step A8, if the game result of the special figure variation display game is a big hit, a fanfare command setting corresponding to the type of big hit (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.

In step A8, when the game process number is “3”, setting of the opening time of the big prize opening, updating of the number of times of opening, setting of information necessary for performing the processing during opening of the big prize opening, etc. are performed. The fanfare / interval processing (step A12) is performed.
In step A8, if the game process number is “4”, 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.

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.
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.
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.
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. 16, 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 with reference to FIG.

   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 operating (step A115; No), it is checked whether the number of fraudulent winnings to the normal variation winning device 37 is equal to or greater than the fraud occurrence determination number (step 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 is prepared for setting a start opening winning effect command by the normal variation winning device 37 (starting opening 2) (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. 17, in the special-purpose start port switch common process, the CPU 111A first monitors 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. 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), the start port winning flag of the monitored start port switch is saved (step A203).

   Thereafter, the update error flag state (0 or 1) is referred to by referring to a table (big hit random number address table) showing the correspondence between the update error flag state (0 or 1) and the load address stored in the ROM 111B in advance. Is acquired (step A204). Then, the value stored in the acquired load address is loaded as a big hit random number (the big hit random number is extracted) (step A205).

   In the jackpot random number address table, the address of the random number counter 608b7 in the random number generation circuit 608 is stored in correspondence with the update error flag “0”, and in the RAM 111C (RWM) in correspondence with the update error flag “1”. Since the address of the big hit random number area is stored, in step S205, the value of the random number counter 608b7 is loaded when the update error flag is “0”, and the big hit random number in the RAM 111C when the update error flag is “1”. The region value will be loaded. Therefore, the RAM 111C functions as a storage unit that stores the acquired address table.

   Thereafter, of the start port 1 switch 36a and the start port 2 switch 37a, information on the number of winnings to the monitored start port switch (for example, the start port 1 switch 36a) is sent to the management device outside the gaming machine 10. The number of times output (start port signal control output number) is loaded (step A206). Then, the loaded value is updated (+1), it is checked whether or not the output count overflows (Step A207), and if it is determined that the output count does not overflow (Step A208; No), the updated value is set to RWM. Are saved in the start port signal output frequency area (step A209), 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 A208; Yes), step A209 is skipped and the process proceeds to step A210.

   Then, in step A210, 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, and a process of determining whether or not the special figure holding number is less than the upper limit value (step A211) is performed.

If it is determined in step A211 that the number of special figure hold is not less than the upper limit (step A211; No), it is checked whether or not the input of the start port switch related to step A202 is the input of the start port 1 switch 36a. (Step A212) When it is determined that the input of the start port 1 switch 36a is (Step A213; Yes), a decoration special figure hold number command (overflow command) is prepared (Step A214), and the command setting process (Step A215) is performed. Then, the special figure start port switch common process is terminated.
If it is determined in step A213 that the input of the start port 1 switch 36a is not input (step A212; No), steps A214 to A215 are skipped, and the special drawing start port switch common process is terminated.

On the other hand, if it is determined in step A211 that the number of special figure hold is less than the upper limit (step A211; Yes), the process proceeds to step A216 and the number of special figure hold to be updated (for example, the number of special figure hold 1) After the processing for updating (+1) is performed, a decoration special figure reservation number command (for example, the start port 1 switch 36a) to be monitored among the start port 1 switch 36a and the start port 2 switch 37a ( MODE) is prepared (step A217), and a special figure reservation number command (ACTION) corresponding to the special figure reservation number is prepared (step A218), and a command setting process (step A219) is performed.
Then, after performing processing (step A220) for calculating the address of the random number saving area corresponding to the special figure hold number, the big hit random number is saved in the random number saving area of the RWM using the calculated address (step A221).

   Thereafter, a table (big hit symbol random number address table) indicating the correspondence between the update error flag state (0 or 1) and the load address for each start port switch stored in advance in the ROM is acquired (step A222). Then, the load address corresponding to the update error flag state (0 or 1) is obtained from the table (step A223). Then, the jackpot symbol random number is saved in the random number save area of the RWM using the value stored in the acquired load address as the jackpot symbol random number (step A224). In the jackpot symbol random number address table, the address of the random number counter 608b7 in the random number generation circuit 608 is stored corresponding to the update error flag “0”, and in the RAM 111C (RWM) corresponding to the update error flag “1”. In step S224, when the update error flag is “0”, the value of the random number counter 608b7 is saved, and when the update error flag is “1”, the address in the RAM 111C is stored. The value of the jackpot symbol random number area will be saved.

   Next, a process of extracting (loading) the fluctuation pattern random number 1 from the fluctuation pattern random number 1 area in the RWM and saving the extracted value in the fluctuation pattern random number 1 saving area of the RWM (step A225), a fluctuation pattern random number in the RWM Extracting (loading) the fluctuation pattern random number 2 from the two areas, saving the extracted value in the RWM random number saving area (step A226), and extracting (loading) the fluctuation pattern random number 3 from the fluctuation pattern random number 3 area in the RWM. Then, a process of saving the extracted value in the random number saving area of the RWM (step A227) is performed.

Subsequently, a special figure hold information determination process (step A228) is performed to determine the result related information corresponding to the start memory before the start timing of the special figure variation display game based on the start memory by winning the start opening. Then, the special figure start port switch common process is terminated.
Even when the normal gate switch (34a) is turned on, the random number generation circuit 608 performs the same process as the above (FIG. 17) regarding the normal random number in the general game process S49 of FIG. The generated hit random number (when normal) or the hit random number in the RAM generated by the program (when update abnormality occurs) is acquired.

Next, a modified example of the gaming machine of the above embodiment will be described.
FIG. 18 shows the procedure of random number error monitoring processing in the first modification. This flowchart is a modification of the random number error monitoring process of FIG. 11 in the above embodiment.
As shown in FIG. 18, in the random number error monitoring process of the first modified example, first, the value of the update error notification register 608b15 in the random number generation circuit 608 is read to check whether an update error has occurred (step S271). ). If it is determined that no update error has occurred (step S272; No), the random number error monitoring process is terminated without doing anything. On the other hand, if it is determined that an update error has occurred (step S272; Yes), the process proceeds to step S275, and whether or not the special figure routine process (A9) in the special figure game process (FIG. 15) is being executed. judge. Then, if it is determined that the special figure routine process (A9) is not being executed (step S275; No), nothing is done and the process exits the random number error monitoring process.

   On the other hand, when it is determined that the special figure routine process (A9) is being executed (step S275; Yes), the process proceeds to step S276, and after interrupt prohibition processing, a random number circuit error notification command is transmitted (step S277). ). This command is a command transmitted to the effect control device 300 (see FIG. 3). When this command is received, the effect control device 300 displays an error occurrence message on the display device 41, for example. Further, when the interrupt prohibition process of step S276 is executed, the timer interrupt process of FIG. 13 is not executed. Further, after the command is transmitted, the process jumps to step S31 of the main process (FIG. 10) according to the symbol “3”. As a result, processing for turning off all output ports is executed, and game control is disabled.

   The special figure normal process (A9) is a process for setting the change start of the special figure change display game, setting the effect, setting information necessary for performing the special figure changing process, and the like. Being played means that you are not playing a big hit game. If the progress of the game is interrupted due to the occurrence of an update error in the random number generation circuit 608 during the big hit game, it will be disadvantageous to the player, which is not desirable. Therefore, in this modification, even if an update error occurs, nothing is done during execution of the special figure normal process (A9), and when an update error occurs when the special figure normal process (A9) is not being executed, An interrupt prohibition process is performed and a random circuit error notification command is transmitted.

   On the other hand, in the random number error monitoring process in the first modified example, there is no process corresponding to steps S273 and S274 in the random number error monitoring process of FIG. 11, and therefore steps S281 and S281 in the initial value random number update process in FIG. S282 is unnecessary. For the same reason, when the first modification is applied, steps S453 to S458 in the random number update process 1 in FIG. 14 are not required. Steps S451 and S452 in FIG. 14 may be the same as steps S271 and S272 in FIG. 18, that is, confirmation of the update error notification register 608b15 and confirmation of occurrence of an update error.

FIG. 19 shows the procedure of random number error monitoring processing in the second modification. The random number error monitoring process of this modified example is the same as step S in the random number error monitoring process of the first modified example of FIG.
If 275 and S276 are omitted and it is determined that an update error has occurred (step S272; Yes), the process proceeds to step S277, and a random circuit error notification command is transmitted. Further, after the command is transmitted, the routine does not jump to step S33 of the main process (FIG. 10), but exits from the random number error monitoring process. According to the second modification, the interrupt prohibition process is not executed, and therefore the timer interrupt process of FIG. 13 is continuously executed. That is, the progress of the game is not interrupted by the occurrence of an update error.

From the above description, in the above embodiment, the auxiliary game is executed according to the game area provided with the start area and the passing of the game ball to the start area, and the auxiliary game has a special result. In a gaming machine comprising a game control device for granting a privilege to a player,
The game control device includes a first random number generation unit and a second random number generation unit that update a random value every predetermined time, and whether or not an abnormality has occurred in the update of the random number value in the first random number generation unit. Update abnormality detection means for detecting, update abnormality information storage means for storing update abnormality information indicating that an abnormality has occurred in the update in the first random number generation means, and that a predetermined random number acquisition condition has occurred An acquisition condition detection means for detecting; a random value acquisition means for acquiring a random value from the first random number generation means when the generation of the predetermined random number acquisition condition is detected by the acquisition condition detection means; and the random value Game result determination means for determining a random number value acquired by the acquisition means and performing a determination process related to the game,
The random value acquisition means refers to the update abnormality information storage means when the occurrence of the predetermined random number acquisition condition is detected by the acquisition condition detection means, and stores the first random number generation means in the update abnormality information storage means In the case where update abnormality information indicating that an abnormality has occurred in the update of the random number value is stored, it is understood that the present invention includes an invention for acquiring a random value from the second random number generation means.

   Although the invention made by the present inventor has been specifically described based on the embodiments, the embodiments disclosed herein are illustrative and non-restrictive in every respect. For example, in the above-described embodiment, the update error notification register 608b10 in which a value indicating an error is set when the random number generation circuit 608 has not updated the random number value, the one-round completion notification register 608b6, and the register 608b9 that notifies that the random number is being updated. A soft random number status register 608b15 for storing a start value setting bit and a tap setting bit indicating whether or not a value (start value) to be set next time is stored in the start value setting register 608b5 is provided as a separate register. However, these registers may be configured as one status register. In this way, the number of registers can be reduced. Further, in this status register, an update error in the counter mode and an update error in the random number mode may be set separately.

In the above embodiment, the embodiment has been described in which when one of the six random number generation blocks generates a random number update error, the program is switched to the random number generation processing by the program. If an error occurs, control may be continued by switching to an unused random number generation block. Also, if the random number generation circuit has an architecture in which blocks cannot be switched, for random numbers that are particularly important (big hit random numbers or random numbers per common figure), two random number generation blocks perform random number update processing in parallel. The user program may be configured to load a random number from a random number generation block and load a random number from the other random number generation block when a random number update error occurs in the random number generation block.
Further, in the above-described embodiment, the present invention is applied to a pachinko gaming machine. However, the present invention is not limited to a pachinko gaming machine, and is a gaming machine such as an arrangement ball gaming machine, a sparrow ball gaming machine, and a slot machine. It is also applicable to.
