Description

  The present invention includes variable display means capable of variably displaying a plurality of types of identification information that can identify each of the identification information, and after a predetermined variable display execution condition is satisfied, the variable display start condition is satisfied. The present invention relates to a gaming machine that starts variable display of identification information and shifts to a specific gaming state advantageous to the player when the display result of variable display of identification information becomes a specific display result.

  As a gaming machine, a game medium such as a game ball is launched into a game area by a launching device, and when a game medium wins a prize area such as a prize opening provided in the game area, a predetermined number of prize balls are paid out to the player. There is something to be done. Further, there is provided a variable display section capable of changing the display state, and configured to give a predetermined game value to the player when the display result of the variable display section is in a predetermined specific display mode. is there.

  The game value is the right that the state of the variable winning ball apparatus provided in the gaming area of the gaming machine becomes advantageous for a player who is easy to win, and the right for becoming advantageous for a player. In other words, or a condition for winning a prize ball is easily established.

  In the gaming machine, when a predetermined transition condition is established, the gaming state is shifted to a specific gaming state that is advantageous to the player. For example, in a pachinko gaming machine, a combination of a specific display mode in which a display result of a variable display unit that displays a special symbol is a predetermined combination is generally referred to as “big hit”. When a big hit occurs, for example, the big winning opening is opened a predetermined number of times, and the game shifts to a big hit gaming state in which a hit ball is easy to win.

  Game progress in the gaming machine is controlled by game control means such as a microcomputer. The game control means includes means for generating a pseudo-random number, and whether or not a predetermined transition condition is satisfied based on the value of the random number (for example, whether or not the display result of variable display is a combination of specific display modes) Or). For example, the game control means determines whether or not a predetermined transition condition is satisfied by determining whether or not a random number value matches a predetermined determination value. When it is determined that a predetermined transition condition is satisfied, the game control means shifts the gaming state to the specific gaming state.

  There is a gaming machine in which the mounting area for mounting the random number generation means and the game control means on a board is reduced by using a microcomputer equipped with a random number circuit as the game control means (see, for example, Patent Document 1). In addition, in the gaming machine described in Patent Document 1, the control burden on the microcomputer is reduced by using a random number generated by a random number circuit mounted on the microcomputer. Further, in Patent Document 1, the random number circuit is initialized from the start of power-on to the gaming machine until the timer interrupt is set, and the game control process for controlling the progress of the game is executed. It is described that it comprises.

(For example, when the clock signal output circuit 524 inputs the random number generation clock signal SI obtained by dividing the reference clock signal CLK by 16, the counter 521 updates the count value C). The numerical value updating means may be configured to set the number of clock signal inputs, which is a condition for updating numerical data (for example, the game control microcomputer 560 executes step S156).

  The gaming control microcomputer executes a processing of step S154b in the numerical computing means for computing a predetermined initial value of the numerical data set by the random number circuit initial setting means using the microcomputer identification information (for example, in the gaming microcomputer) The game control microcomputer 560 calculates an ID number and a predetermined value (for example, a part for obtaining a calculated value by adding a predetermined value to the ID number), and the random number circuit initial setting means includes: An initial value is set based on the value calculated by the calculation by the numerical calculation means (for example, when the gaming microcomputer executes the process of step S154b, the calculated calculated value is set as the initial value of the count value).

The random number circuit stores numerical data updated by the numerical value updating means in the random number storage means based on the input of the winning detection signal from the winning detection means. A latch signal output means (for example, a latch signal generation circuit 533) that outputs a latch signal for instructing to perform the instruction, and the latch signal output means that the winning detection signal is continuously input from the winning detection means for a predetermined period. (For example, the random number read signal output from the random number read signal output circuit 526 when the timer circuit 534 measures a predetermined period (for example, 3 ms). (For example, the latch signal generation circuit 533 outputs the random number read signal output from the random value read signal output circuit 526 to the inverted clock signal SI2 output from the inversion circuit 532). The portion may be configured so as to be output to the random value storage circuit 531 as the latch signal SL in synchronization with the rising edge.

The circuit outputs a latch signal for instructing the random number storage means to store numerical data to be updated by the numerical value updating means based on the input of the winning detection signal from the winning detection means. For example, the latch signal generation circuit 533) includes a latch signal output unit that outputs a latch signal (for example, a latch signal generation circuit) on condition that the winning detection signal is continuously input from the winning detection unit for a predetermined period. 533 is the random number value read signal output from the random number value read signal output circuit 526 and the rising edge of the inverted clock signal SI2 output from the inversion circuit 532 is The random number reading means synchronizes with the edge and outputs the random number value storage circuit 531 to the random number value storage circuit 531), and the random number reading means continues to receive the winning detection means while the timer interruption processing is executed a predetermined number of times by the interruption processing execution means. (For example, when the game control microcomputer 560 executes the process of step S322, the number of executions of the timer interrupt process indicated by the interrupt counter is a predetermined number of times (for example, 3), the random number value stored in the random number storage unit is read (for example, the CPU 56 stores the random R value stored as the random number value from the random number value storage circuit 531 of the random number circuit 503). The predetermined period (for example, 3 ms) is shorter than the period (for example, 6 ms) in which the predetermined number of timer interruption processes are executed. It may have been made.

  In the initial setting, the random number circuit initial setting means sets the order of values from a predetermined initial value to a predetermined final value of the numerical data updated by the numerical value updating means (for example, a permutation of count values C updated by the counter 521). Numerical value order setting means for setting whether or not to change (for example, a part for executing step S158 in the game control microcomputer 560), the random number circuit updates the numerical data up to a predetermined final value by the numerical value updating means. A notification signal output means (for example, an output terminal of the counter 521) for outputting a notification signal indicating that the numerical data has been updated to a predetermined final value, and a random number based on the output of the notification signal. When the circuit initial setting means has been set to change the order of numerical data from a predetermined initial value to a predetermined final value, A numerical order changing means for changing the order of numerical data updated by the means from a predetermined initial value to a predetermined final value (for example, a part for executing step S24 in the game control microcomputer 560).

In addition, since the randomness of random numbers can be improved, the timing of random number generation can be made difficult to be recognized by a player or a game store, and by generating a capture signal using a radio signal for a gaming machine It is possible to prevent the condition for shifting to the specific gaming state from being illegally established.

  In the invention described in claim 2, since it is configured to set whether or not each of a plurality of random number circuits having different predetermined ranges of numerical data that can be updated can be used, only the random number circuit to be used is used. By setting, the range of the random number value to be generated can be set appropriately. Therefore, it is possible to prevent unnecessary random numbers from being processed during the execution of the timer interrupt process, and the control burden on the game control microcomputer can be reduced.

  In the invention according to claim 3, since the value as the maximum value of the predetermined range in which the numerical data is updated is set in advance, a value larger than the range of random numbers used during execution of the timer interrupt process Can be prevented, and the processing load on the random number circuit and the game control microcomputer can be reduced. In addition, when the predetermined maximum value that is set is equal to or less than the predetermined lower limit value, the predetermined maximum value is reset, so that a malfunction of the game control microcomputer or a radio signal is used. It is possible to prevent an excessively small value from being set as the maximum value of the random number due to an action such as generating a captured signal to the gaming machine.

  In the invention described in claim 4, since the numerical value updating means is configured to preset the number of clock signal inputs, which is a condition for updating numerical data, the randomness of the random number generated by the random number circuit is further improved. be able to.

  In the invention according to claim 5, since the initial value is set based on the value calculated by the calculation using the microcomputer identification information, the randomness of the random number generated by the random number circuit is further improved. Can do. For this reason, it is possible to make it difficult to recognize the initial value of the random number simply by looking at the microcomputer identification information, and the security can be improved.

  In the invention described in claim 6, since the predetermined initial value is updated when the numerical data is updated to the predetermined final value, the randomness of the random number generated by the random number circuit is further improved. Can do.

  According to the seventh aspect of the invention, when the random number storage means stores the random number based on the output of the latch signal, the latch signal is supplied on condition that the winning detection signal is input continuously for a predetermined period. Since it is configured to output, it is possible to prevent the occurrence of noise from being erroneously recognized as the input of the input detection signal, outputting the latch signal, and storing the generated random number. In addition, it is possible to reduce the possibility that a random number generated by an illegal latch signal is stored due to an output of a latch signal due to an action such as generating a capture signal using a radio signal to the gaming machine. .

  In the invention described in claim 8, when the random number is read from the random number storage means, the random number is read from the random number storage means on condition that the winning detection signal is continuously input while the timer interruption process is executed a predetermined number of times. Therefore, it is possible to prevent the random number from being read again after the random number is read and before the value of the random number stored in the random number storage unit is updated. Therefore, it is possible to prevent a random number having the same value as the random number read from the previous random number storage unit from being read again.

  According to the ninth aspect of the invention, when the numerical data is updated to the predetermined final value, the arrangement order from the predetermined initial value to the predetermined final value is updated, so the random number circuit generates The randomness of random numbers can be further improved.

Of the winning balls that have won the special variable winning ball device 20 and led to the back of the game board 6, the winning ball that has entered one (V winning area: special area) is detected by the V winning switch 22 and then counted by the count switch 23. The game ball that has been detected and entered the other area is detected by the count switch 23 as it is. On the back of the game board 6, a solenoid 21A for switching the route in the special winning opening is also provided.

  When the game ball passes through the gate 32 and is detected by the gate switch 32a, the variable display of the normal symbol display 10 is started. In this embodiment, variable display is performed by alternately lighting left and right lamps (designs can be visually recognized when lit). For example, if the left lamp is lit at the end of variable display, it is a win. When the stop symbol on the normal symbol display 10 is a predetermined symbol (winning symbol), the variable winning ball device 15 is opened for a predetermined number of times. In the vicinity of the normal symbol display 10, a normal symbol start memory display 41 having a display unit with four LEDs for displaying the number of winning balls that have passed through the gate 32 is provided. Each time there is a game ball passing through the gate 32, the normal symbol start memory display 41 increases the number of LEDs to be turned on by one. Each time variable display on the normal symbol display 10 is started, the number of LEDs to be lit is reduced by one.

  The game board 6 is provided with a plurality of winning holes 29, 30, 33, 39, and winning of game balls to the winning holes 29, 30, 33, 39 is performed by winning hole switches 29a, 30a, 33a, 39a, respectively. Detected. Each winning opening 29, 30, 33, 39 constitutes a winning area provided in the game board 6 as an area for accepting game media and allowing winning.

  A game ball launched from the ball striking device by the player's operation enters the game area 7 through the hit ball rail, and then descends the game area 7. When the game ball enters the start winning opening 14 and is detected by the start opening switch 14a, the special symbol on the special symbol display 8 starts variable display (variation) if the variable display of the symbol can be started. If the variable display of the symbol cannot be started, the number of reserved memories is increased by one.

  The variable display of the special symbol on the special symbol indicator 8 stops when a certain time has passed. If the special symbol (stop symbol) at the time of stoppage is a jackpot symbol (specific display result), the game shifts to a jackpot gaming state. That is, the special variable winning ball apparatus 20 is released until a predetermined time elapses or until a predetermined number (for example, 10) of gaming balls wins. When the game ball is won in the V winning area while the special variable winning ball apparatus 20 is opened and is detected by the V winning switch 22, a continuation right is generated and the special variable winning ball apparatus 20 is opened again. The generation of the continuation right is allowed a predetermined number of times (for example, 15 rounds). In addition, without providing the V winning area, the special variable winning ball apparatus 20 may always be allowed to be released up to the final round (for example, up to 15 rounds).

  When the special symbol on the special symbol display 8 at the time of stoppage is a jackpot symbol (probability variation symbol) with a probability variation, the probability of the next jackpot increases. That is, it becomes a more advantageous state for the player in a probable change state.

  When the game ball passes through the gate 32, the normal symbol display unit 10 is in a state where the normal symbol is variably displayed. Further, when the stop symbol on the normal symbol display 10 is a predetermined symbol (winning symbol), the variable winning ball device 15 is opened for a predetermined time. Further, in the probability variation state, the probability that the stop symbol in the normal symbol display 10 becomes a winning symbol is increased, and the opening time and the number of times of opening of the variable winning ball device 15 are increased. That is, the opening time and the number of times of opening of the variable winning ball device 15 can be increased when the stop symbol of the normal symbol is a winning symbol or the stop symbol of the special symbol is a probabilistic symbol. It changes to an advantageous state. Note that increasing the number of times of opening is a concept including changing from a closed state to an open state.

  Next, the structure of the back surface of the pachinko gaming machine 1 will be described with reference to FIG. FIG. 3 is a rear view of the gaming machine as seen from the back side.

  As shown in FIG. 3, on the back side of the gaming machine, a variable display control unit 49 including an effect control board 80 on which an effect control microcomputer for controlling the variable display device 9 is mounted, a game control microcomputer, and the like are mounted. A game control board (main board) 31 is installed. In addition, a payout control board 37 on which a payout control microcomputer for performing ball payout control is mounted is installed. The production control microcomputer controls the variable display device 9 provided on the game board 6, and various decoration LEDs, a decoration lamp 25, a top frame lamp 28a, a left frame lamp 28b provided on the frame side, and The lighting of the right frame lamp 28c is controlled, and the sound generation from the speaker 27 is controlled.

  Further, a power supply substrate 910 and a touch sensor substrate 91 on which a power supply circuit for generating DC30V, DC21V, DC12V, and DC5V is mounted are provided. Most of the power supply substrate 910 overlaps with the main substrate 31, but there is an exposed portion that is exposed so as not to overlap with the main substrate 31. The exposed portion is operated by supplying power to the main board 31 and each electrical component control board (production control board 80 and payout control board 37) in the gaming machine 1 and each electrical component provided in the gaming machine. A power switch is provided as a power supply permission means for executing or shutting off power supply to the component. Furthermore, a replaceable fuse is provided inside the power switch at the exposed portion (inside the substrate).

  An electrical component control means including an electrical component control microcomputer is mounted on the electrical component control board. The electrical component control means is an electrical component (game device: ball payout device 97, variable display device 9, lamp, LED, etc.) provided in the gaming machine according to a command signal (control signal) as a command from the game control means or the like. The light emitter, speaker 27, etc.). Hereinafter, description may be made by including the main board 31 in the electric component control board. In that case, the electrical component control means mounted on the electrical component control board includes a game control means and a means for controlling the electrical components provided in the gaming machine according to a command signal from the game control means or the like. Point to. A substrate on which a microcomputer other than the main substrate 31 is mounted may be referred to as a sub-substrate.

  On the back side of the gaming machine, a terminal board 160 provided with terminals for outputting various information to the outside of the gaming machine is installed above. The terminal board 160 includes at least a ball break terminal for introducing the output of the ball break detection switch 167 and outputting it externally, a prize ball terminal for outputting prize ball information (prize ball number signal) and a ball. A ball lending terminal for externally outputting lending information (ball lending number signal) is provided. Further, an information terminal board (information output board) 36 having terminals for outputting various information from the main board 31 to the outside of the gaming machine is installed near the center.

  The game balls stored in the storage tank 38 pass through the guide rail 39 and reach the ball payout device covered with the payout case 40A through the curve rod. A ball break switch 187 as a game medium break detection means is provided on the upper part of the ball payout device. When the ball break switch 187 detects a ball break, the dispensing operation of the ball dispensing device stops. The ball break switch 187 is a switch for detecting the presence or absence of a game ball in the game ball passage, but the ball break detection switch 167 for detecting the shortage of supply balls in the storage tank 38 is also an upstream portion (storage tank 38). In the vicinity of the head). When the ball break detection switch 167 detects a shortage of game balls, the game machine is replenished to the game machine from the supply mechanism provided on the gaming machine installation island.

  When a large number of game balls as prizes based on winning a prize or a game ball based on a ball lending request are paid out and the hitting ball supply tray 3 is full, the game balls are guided to the surplus ball receiving tray 4 through the surplus ball passage. When the game ball is further paid out, a sensing lever (not shown) presses a full tank switch (not shown) as a storage state detection means, and the full tank switch as a storage state detection means is turned on. In this state, the rotation of the payout motor in the ball payout device stops, the operation of the ball payout device stops, and the driving of the hitting ball launching device also stops.

  FIG. 4 is a block diagram illustrating an example of a circuit configuration in the main board 31. 4 also shows a payout control board 37, a lamp driver board 35, an audio output board 70, an interface board 66, a relay board 77, and an effect control board 80 mounted on the gaming machine. The main board 31 includes a basic circuit (corresponding to game control means) 53 for controlling the pachinko gaming machine 1 according to a program, a gate switch 32a, a start port switch 14a, a V winning switch 22, a count switch 23, a winning port switch 29a, 30a, 33a, 39a and an input driver circuit 58 for supplying a signal from the total winning counting switch 34 to the basic circuit 53, a solenoid 16 for opening / closing the variable winning ball device 15, a solenoid 21 for opening / closing the special variable winning ball device 20, and A solenoid circuit 59 for driving the solenoid 21A for switching the route in the special winning opening according to a command from the basic circuit 53 is mounted.

  It should be noted that switches such as the gate switch 32a, the start port switch 14a, the V winning switch 22, the count switch 23, the winning port switches 29a, 30a, 33a, 39a, the all winning count switch 34, and the like may be referred to as sensors. . That is, the name of the game medium detection means is not limited as long as it is a game medium detection means (game ball detection means in this example) that can detect a game ball. Each of the start port switch 14a, the count switch 23, and the winning port switches 29a, 30a, 33a, and 39a that perform winning detection is also a winning detection means that detects the winning of a game ball in the winning area. Note that even if a passing gate such as the gate 32 is used, if a prize ball is paid out, a game ball entering the passing gate becomes a winning and a switch provided on the passing gate (for example, The gate switch 32a) becomes a winning detection means. Furthermore, in this embodiment, the game ball that has won the V winning area is detected by the V winning switch 22 and also by the count switch 23. Therefore, the number of game balls won in the special winning opening corresponds to the number detected by the count switch 23. However, the game balls won in the V prize area are detected only by the V prize switch 22, and the number of game balls won in the big prize opening is the number detected by the V prize switch 22 and the number detected by the count switch 23. You may make it become the sum. Further, the V winning area may not be provided, and a continuation right may always be generated in rounds other than the final round.

  The basic circuit 53 includes a ROM 54 for storing a program for game control (game progress control), a RAM 55 as storage means (variation data storage means for storing fluctuation data) used as a work memory, and a control operation according to the program. A game control microcomputer 560 having a CPU 56 and an I / O port unit 57 are included. In this embodiment, the ROM 54 and the RAM 55 are built in the game control microcomputer 560. That is, the game control microcomputer 560 is a one-chip microcomputer. The one-chip microcomputer only needs to include at least the RAM 55, and the ROM 54 may be external or internal. Further, the I / O port unit 57 may be built in a one-chip microcomputer.

  In the game control microcomputer 560, the CPU 56 executes control in accordance with the program stored in the ROM 54. Therefore, hereinafter, the game control microcomputer 560 executes (or performs processing) specifically. Is that the CPU 56 executes control according to the program. The same applies to microcomputers mounted on substrates other than the main substrate 31. The game control means is realized by a basic circuit 53 including a game control microcomputer 560.

  The RAM 55 is a backup RAM as a non-volatile storage means that is partially or entirely backed up by a backup power source created on the power supply substrate 910. That is, even if the power supply to the gaming machine is stopped, a part or all of the contents of the RAM 55 is stored for a predetermined period (until the capacitor as the backup power supply is discharged and the backup power supply cannot be supplied). In particular, at least data (a special symbol process flag or the like) corresponding to the game state, that is, the control state of the game control means, and data indicating the number of unpaid prize balls are stored in the backup RAM. The data corresponding to the control state of the game control means is data necessary for restoring the control state before the occurrence of a power failure or the like based on the data when the power is restored after a power failure or the like occurs. Further, the data corresponding to the control state is defined as the data indicating the number of unpaid prize balls and the data indicating the game progress state. In this embodiment, it is assumed that the entire RAM 55 is backed up.

  A reset signal from the power supply board 910 is input to the reset terminal of the game control microcomputer 560. The reset signal from the power supply board 910 is also input to the reset terminal of the payout control microcomputer. When the reset signal becomes high level, the game control microcomputer 560 and the payout control microcomputer become operable, and when the reset signal becomes low level, the game control microcomputer 560 and the payout control microcomputer stop operating. It becomes a state. Accordingly, during the period in which the reset signal is at a high level, an allowable signal that allows the operation of the game control microcomputer 560 and the payout control microcomputer is output, and in the period in which the reset signal is at a low level, An operation stop signal for stopping the operations of the game control microcomputer 560 and the payout control microcomputer is output. The reset circuit may be mounted on each electric component control board (including the main board 31), or a reset circuit is mounted on one or more of the plurality of electric component control boards, and a reset signal is output therefrom. May be supplied to another electric component control board.

  Furthermore, a power-off signal indicating that the power supply voltage from the power supply board 910 has decreased to a predetermined value or less is input to the input port of the basic circuit 53 via the payout control board 37. A clear signal indicating that the clear switch for instructing clearing of the contents of the RAM is operated is input to the input port of the basic circuit 53.

  The clear signal is branched at the main board 31 and is also supplied to the payout control board 37. The state of the clear signal input by the game control microcomputer 560 via the input port may be output to the payout control board 37 via the output port.

  In this embodiment, the effect control means (configured by the effect control microcomputer) mounted on the effect control board 80 receives the effect control command from the game control microcomputer 560 via the relay board 77. The display control and the like of the variable display device 9 that receives and variably displays decorative symbols are performed.

  FIG. 5 is a block diagram showing a circuit configuration of the main board 31 and signal lines of an effect control command transmitted from the main board 31 to the effect control board 80. As shown in FIG. 5, in this embodiment, the game control microcomputer 560 mounted on the main board 31 produces an effect control command by using eight signal lines CD0 to CD7 for transmitting the effect control signal. Transmit to the control board 80. In addition, a signal line of an effect control INT signal for transmitting and receiving a strobe signal is also wired between the main board 31 and the effect control board 80.

  As shown in FIG. 5, wiring from the start port switch 14a is connected to the main board 31. The main board 31 is also provided with wiring from the special variable winning ball apparatus 20 which is a large winning opening, and various switches 29a, 30a, 33a, 39a for detecting the winning of game balls to other winning holes. It is connected. Furthermore, the main board 31 is connected to a solenoid 16 that opens and closes the variable winning ball device 15, a solenoid 21 that opens and closes the special variable winning ball device 20, and a wiring to the solenoid 21A for switching the path in the special winning opening. .

  The main board 31 includes a game control microcomputer 560, an input driver circuit 58, and an output circuit 59. The game control microcomputer 560 operates in accordance with a clock circuit 501, a reset controller 502 that functions as a system reset means, random number circuits 503a and 503b, a ROM 54 that stores a game control program, a RAM 55 that is used as a work memory, and a program. CPU 56, CTC 504 for sending an interrupt request signal to CPU, and I / O port 506 are incorporated.

The clock circuit 501 outputs a system clock signal to the CPU 56, and outputs a reference clock signal CLK having a predetermined period generated by dividing the system clock signal by 2 ⁷ (= 128) to the random number circuits 503a and 503b. . When a low level signal is input for a predetermined period, the reset controller 502 outputs a predetermined initialization signal to the CPU 56 and the random number circuits 503a and 503b to reset the game control microcomputer 560.

  Further, in this embodiment, as shown in FIG. 5, the game control microcomputer 560 is equipped with two random number circuits 503a and 503b having different ranges of random value values that can be generated. The random number circuit 503a is a random number circuit (hereinafter also referred to as a 12-bit random number circuit) that generates a 12-bit pseudo-random number. The 12-bit random number circuit 503a has a function of generating a random number having a value in a range that can be generated by 12 bits (that is, a range from 1 to 4095). The random number circuit 503b is a random number circuit (hereinafter also referred to as a 16-bit random number circuit) that generates a 16-bit pseudo-random number. The 16-bit random number circuit 503b has a function of generating a random number having a value in a range that can be generated by 16 bits (that is, a range from 1 to 65535). In this embodiment, the case where the game control microcomputer 560 includes two random number circuits is described. However, the game control microcomputer 560 may include three or more random number circuits. In this embodiment, when the 12-bit random number circuit 503a and the 16-bit random number circuit 503b are comprehensively expressed, or when indicating either the 12-bit random number circuit 503a or the 16-bit random number circuit 503b, This is called a random number circuit 503.

  Next, the configuration of the random number circuit 503 will be described. FIG. 6 is a block diagram illustrating a configuration example of the random number circuit 503. In this embodiment, the basic configurations of the 12-bit random number circuit 503a and the 16-bit random number circuit 503b are the same. As shown in FIG. 6, the random number circuit 503 includes a counter 521, a comparator 522, a count value permutation changing circuit 523, a clock signal output circuit 524, a count value update signal output circuit 525, a random value read signal output circuit 526, and a random number update. A system selection signal output circuit 527, a selector 528, a random number circuit activation signal output circuit 530, a random value storage circuit 531, an inversion circuit 532, a latch signal generation circuit 533, and a timer circuit 534 are included.

  In this embodiment, the random number circuit 503 determines whether or not the display result of variable display of a plurality of types of identification information is a specific display result (for example, the combination of display symbols of the special symbol display device 8 is a combination of jackpot symbols) A random number for determination is generated. If the game control microcomputer 560 determines that the specific display result is based on the random number generated by the random number circuit 503, the game state is shifted to a specific game state (for example, a big hit game state) advantageous to the player. . It should be noted that a random number for determination other than the jackpot symbol, such as a random number for probability variation determination for determining whether or not the random number generated by the random number circuit 503 is a probability variation, and a random number for variation pattern determination for determining a variation pattern for a special symbol. It may be used as

  The counter 521 receives the predetermined signal selected by the selector 528 and outputs a count value C in response to the signal input from the selector 528. In this case, the counter 521 inputs a predetermined initial value, cyclically updates the count value C from the initial value to a predetermined final value according to a certain rule, and outputs it. Further, when the count value C is updated to the final value, the counter 521 outputs a notification signal indicating that the count value C has been updated to the final value to the CPU 56. In this embodiment, when a notification signal is output from the counter 521, the CPU 56 updates the initial value.

  In this embodiment, every time a signal is input from the selector 528 (every time a rising edge in the signal from the selector 528 is input), the counter 521 increments the count value C from “0” to “4095” by one. Count up. Further, when the counter 521 counts up the count value C to “4095”, the counter 521 outputs a notification signal indicating that the count value C has been updated to the final value to the CPU 56. Then, the CPU 56 inputs a notification signal from the counter 521 and updates the initial value. Then, the counter 521 counts up the count value C again from the initial value updated by the CPU 56 to “4095”. Further, when counting up to “4095”, the counter 521 starts counting from “0” again. Then, the counter 521 outputs a notification signal to the CPU 56 when it counts up to a value (final value) immediately before the updated initial value. In this embodiment, the comparator 522 outputs a notification signal to the counter 521 when all count values are input, as will be described later. In this case, when the notification signal is input from the comparator 522, the counter 521 resets the count value to “0”.

  The count value permutation change circuit 523 includes a count value permutation change register (RSC) 536, an update rule selection register (RRC) 542, and an update rule memory 543. The count value permutation change register 536 stores count value permutation change data “01h” for changing the permutation (order of arrangement from the initial value to the final value), which is the update order of the count value C counted up by the counter 521. . When the numerical value permutation change data “01h” is stored in the count value permutation change register 536, the count value permutation change circuit 523 displays the count value C permutation that the counter 521 counts up and updates. The permutation is changed to a different permutation from when “01h” is not stored.

  FIG. 7 is an explanatory diagram illustrating an example of the update rule selection register 542. The update rule selection register 542 is a register that sets an update rule used for rearranging the order of count values output from the counter 521 (changing the permutation). In this embodiment, an update rule used for changing the permutation of count values output from the counter 521 is set by setting a register value in the update rule selection register 542. As shown in FIG. 7, the update rule selection register 542 is an 8-bit register, and the initial value is set to “0 (= 00h)”. The update rule selection register 542 is configured in a state where bits 0 to 3 can be written and read. In addition, the update rule selection register 542 is configured in a state where bits 4 to 7 cannot be written or read. Therefore, even if control is performed to write values to bits 4 to 7 of the update rule selection register 542, it is invalid, and all the values read from bits 4 to 7 are “0 (= 0000b)”.

  The value (register value) of the update rule selection register 542 is changed from “0 (= 00h)” to “15” in response to the count value permutation change data “01h” being written in the count value permutation change register 536. (= 0Fh) ”is updated cyclically. That is, each time the count value permutation data “01h” is written to the count value permutation change register 536, the register value of the update rule selection register 542 is incremented by “1” from “0”. Return to "0".

  FIG. 8 is an explanatory diagram showing an example of the update rule memory 543. As shown in FIG. 8, the update rule memory 543 stores the value (register value) of the update rule selection register 542 and the count value update rule in association with each other. In the example shown in FIG. 8, for example, when the register value 1 is set in the update rule selection register 542, it can be seen that the permutation of the count values output by the counter 521 is changed using the update rule B. In FIG. 8, the update rule A is the same update rule as that for the counter 521 to update the count value C, and is stored in the update rule memory 543 in association with the register value “0”. Also, in the update rule memory 543, update rules B to P different from the update rule in which the counter 521 updates the count value C are stored in association with the register values “1” to “15”.

  When the count value permutation change data “01h” is written in the count value permutation change register 536, the count value permutation change circuit 523 first counts from the counter 521 until the final count value “4095” is first input. The count value is output as it is according to the currently set update rule. The count value permutation changing circuit 523 changes the count value update rule when the final value “4095” of the count value is input from the counter 521. When the initial value is changed by the CPU 56, the count value permutation changing circuit 523 inputs the final value after the change (the value immediately before the initial value) from the counter 521, and updates the count value. Will be changed.

  The count value permutation change circuit 523 selects an update rule corresponding to the register value of the update rule selection register 542 from the update rule memory 543, and sets it as an update rule used for changing the count value permutation. The count value permutation change circuit 523 changes the permutation from the initial value of the count value to the final value according to the set update rule when the counter 521 starts updating the count value again in order from the initial value “0”. To do. When the initial value is changed by the CPU 56, the count value permutation changing circuit 523 starts counting in accordance with the set update rule when the counter 521 starts updating the count value in order from the changed initial value. The permutation from the initial value to the final value will be changed. Then, the count value permutation change circuit 523 outputs a count value according to the changed permutation.

  In this embodiment, when the maximum random number to be generated is limited by setting the maximum random number in a random number maximum value setting register 535 described later, the count value permutation changing circuit 523 counts The value C is limited to the maximum random number or less, and the permutation is changed and output. For example, it is assumed that the random number maximum value “256” is set in the random number maximum value setting register 535, and the count value permutation changing circuit 523 changes the update rule A to the update rule B to change the count value permutation. Shall. In this case, the count value permutation changing circuit 523 changes the count value permutation to “256 → 255” according to the update rule B based on the random number maximum value “256” set in the random number maximum value setting register 535 of the comparator 522. → → → 0 "and output.

  As described above, when the count value permutation change data “01h” is written in the count value permutation change register 536, the count value permutation change circuit 523 changes the update rule to use the permutation of the count value C. Change and output. Therefore, the randomness of the random number generated by the random number circuit 503 can be improved.

  FIG. 9 is an explanatory diagram illustrating an example in which the count value permutation changing circuit 523 changes the permutation of count values output from the counter 521. As shown in FIG. 9, the CPU 56 writes the count value permutation change data “01h” into the count value permutation change register 536 at a predetermined timing. Then, 1 is added to the register value of the update rule selection register 542. For example, the register value of the update rule selection register 542 is updated from “0” to “1”. When the register value is updated, the count value permutation changing circuit 523 updates the “update rule A” corresponding to the register value “0” before the update until the final value “4095” of the count value is input from the counter 521 for the first time. The count value is updated according to "." At this time, the count value permutation changing circuit 523 outputs the count values in a permutation of “0 → 1 →... → 4095” according to the update rule A.

  When the final value “4095” of the count value is input from the counter 521, the count value permutation changing circuit 523 selects “update rule B” corresponding to the updated register value “1” from the update rule memory 543. To set. When the count value permutation changing circuit 523 starts to input the count values after the initial value “0” from the counter 521 again, the count value permutation changing circuit 523 changes the permutation of the count values according to the selected “update rule B” and outputs it. In this example, the count value permutation changing circuit 523 changes the permutation from “0 → 1 →... → 4095” to “4095 → 4094 →... → 0” and outputs the count value.

  Thereafter, the count value permutation change register 536 is reset in response to the count value permutation change circuit 523 starting the count value updating operation in accordance with the updated update rule, as will be described later. Then, until the next count value permutation change data “01h” is written to the count value permutation change register 536, the count value permutation change circuit 523 counts the permutation as “4095 → 4094 →. Continue to output values.

  When the count value permutation change data “01h” is written again to the count value permutation change register 536 by the CPU 56, the register value of the count value permutation change register 536 is updated from “1” to “2”. When the final value “4095” of the count value is input from the counter 521, the count value permutation changing circuit 523 selects and sets “update rule C” corresponding to the register value “2” from the update rule memory 543. . When the count value permutation changing circuit 523 starts to input the count value after the initial value “0” again from the counter 521, the count value permutation changing circuit 523 updates and outputs the count value permutation in accordance with the “update rule C” selected and set. In this example, the count value permutation changing circuit 523 changes the permutation from “4095 → 4094 →... → 0” to “1 → 3 →... → 4095 → 0 →. Is output.

  As described above, the count value permutation register 536 is reset, and then the count value permutation data “01h” is written again into the count value permutation change register 536, whereby the permutation of the count values can be further changed.

  FIG. 10 is an explanatory diagram illustrating an example of the count value permutation change register 536. The count value permutation change register 536 is a register that sets count value permutation change data “01h” for changing the permutation of count values counted up by the counter 521. As shown in FIG. 10, the count value permutation change register 536 is a readable 8-bit register, and the initial value is set to “0 (= 00h)”. Further, count value permutation change register 536 is configured such that only bit 0 can be written and read. That is, count value permutation change register 536 is configured such that bits 1 to 7 cannot be written or read. Therefore, even if control is performed to write values to bits 1 to 7 of the count value permutation change register 536, it is invalid, and all the values read from bits 1 to 7 are “0 (= 0000000b)”.

  Note that the value of the count value permutation change register 536 is reset by the CPU 56 in response to the count value permutation change circuit 523 starting a count value update operation in accordance with the updated update rule. In this case, the CPU 56 returns the value written in the count value permutation change register 536 from the count value permutation change data “01h” to the initial value “0 (= 00h)”.

  The comparator 522 includes a random number maximum value setting register (RMX) 535 that stores random number maximum value setting data for designating the maximum value of random R (random number maximum value). The comparator 522 limits the update range of the count value updated by the counter 521 according to the random number maximum value indicated in the random number maximum value setting data stored in the random number maximum value setting register 535. In this embodiment, the comparator 522 has a random number maximum value (for example, “00FFh”) indicated by the count value input from the counter 521 and the random number maximum value setting data (for example, “00FFh”) stored in the random number maximum value setting register 535. 256 "). When the comparator 522 determines that the input count value is equal to or less than the random number maximum value, the comparator 522 outputs the input count value to the random value storage circuit 531.

  In this embodiment, the comparator 522 specifically performs the following control. The comparator 522 obtains the initial value of the count value from the CPU 56 when updating the initial value of the count value, and obtains the number of count values from the initial value to the maximum random number. For example, when the initial value of the count value is “157” and the maximum random number value is “256”, the comparator 522 calculates the number of count values from the initial value to the maximum random number value as “100”. Further, the comparator 522 counts up how many count values are input from the initial value as the count values are input from the count value permutation changing circuit 523. When the number of input count values from the initial value reaches “100”, the comparator 522 determines that all count values from the initial value “157” to the maximum value “256” have been input. Then, the comparator 522 outputs a notification signal indicating that all count values have been input to the counter 521. By determining based on the number of count values, even when the count value permutation circuit 523 has changed the count value permutation, the comparator 522 limits the update range of the count value to the maximum random number or less. When all count values are input, a notification signal can be output to the counter 521.

  An operation in which the comparator 522 limits the update range of the count value will be described. In this example, a case where the count value permutation changing circuit 523 selects the update rule A and the random number maximum value “256” is set in the random number maximum value setting register 535 will be described.

  While the counter 521 is updating the count value from “0” to “256”, the count value permutation changing circuit 523 updates based on the random number maximum value “256” set in the random number maximum value setting register 535. In accordance with rule A, the count values from “0” to “256” are output to the comparator 522 as they are. In this case, the count value permutation changing circuit 523 receives the value of the random number maximum value “256” from the comparator 522, determines whether the count value input from the counter 521 is larger than the random number maximum value, and the update rule is changed. Even when it is set (for example, update rule B), the count values from “257” to “4095” are compared based on the random number maximum value “256” set in the random number maximum value setting register 535. The data is not output to the device 522. For example, when the initial value is set to “0” and the count value is updated to the final value “256”, the counter 521 outputs a notification signal to the CPU 56. When the notification signal is output, the CPU 56 changes the initial value of the count value of the counter 521. In this example, it is assumed that the initial value is changed to “50” by the CPU 56.

  Based on the update rule A, while the count value is input from “0” to “255” from the count value permutation changing circuit 523, the comparator 522 inputs the count value below the maximum random number “256”. Therefore, the input count value is output to the random value storage circuit 531 as it is. Next, when the count value input from the count value permutation changing circuit 523 reaches “256”, the comparator 522 outputs the input count value to the random value storage circuit 531 and all the values from the initial value to the maximum value. A notification signal indicating that the count value is input is output to the counter 521. Specifically, the comparator 522 receives an initial value (“0” in this example) of the count value from the CPU 56 when changing the initial value of the count value, and the random number maximum value (the main value) from the initial value “0”. In the example, the number of count values up to “256” (in this example, “257”) is obtained. When the number of count values input from the count value permutation changing circuit 523 reaches 257, a notification signal indicating that all count values have been input is output to the counter 521. In this example, since the CPU 56 changes the initial value to “50”, the counter 521 does not reset the count value even when the notification signal is input from the comparator 522, and the changed initial value “50”. The count value is updated.

  While the counter 521 updates the count value from the changed initial value “50” to “256”, the count value permutation changing circuit 523 sets the random number maximum value “256” set in the random number maximum value setting register 535. Based on the update rule A, the count values from “50” to “256” are output to the comparator 522 as they are. Further, the count value permutation changing circuit 523 does not output the count values from “257” to “4095” to the comparator 522 based on the random number maximum value “256” set in the random number maximum value setting register 535. When the count value to be updated by the counter 521 makes one round (when updated 257 times), when the count value permutation change data is written in the count value permutation change register 536, the count value permutation change circuit 523 Change the permutation of count values and output. For example, when the update rule is changed to the update rule B, the count value permutation changing circuit 523 changes the count value permutation from “256 → 255 →... 50” and outputs the result.

  While the count values from “256” to “50” are input from the count value permutation changing circuit 523, the comparator 522 outputs the input count value as it is to the random value storage circuit 531. Next, when the count value input from the count value permutation change circuit 523 reaches “50”, the comparator 522 outputs the input count value to the random value storage circuit 531 and all the values from the initial value to the maximum value. A notification signal indicating that the count value is input is output to the counter 521. Specifically, the comparator 522 receives the initial count value (“50” in this example) from the CPU 56 when the initial count value is changed, and the random number maximum value (this In the example, the number of count values up to “256” (in this example, “207”) is obtained. When the number of count values input from count value permutation changing circuit 523 reaches 207, a notification signal indicating that all count values have been input is output to counter 521.

  Even when the count value permutation changing circuit 523 changes the count value permutation, the comparator 522 outputs a notification signal to the counter 521 when the number of count values reaches 207. By doing so, even if the permutation of the count values is changed, the notification signal is counted based on the input of all the count values from the initial value “50” to the maximum value “256”. 521 can be output.

  When the notification signal is input from the comparator 522, the counter 521 resets the initial value of the count value and returns it to “0”. Then, the counter 521 updates the count value from “0”. When the value of the counter 521 is updated again from “0”, the count value permutation changing circuit 523 outputs the count values from “49” to “0” to the comparator 522 based on the count value from the counter 521. The comparator 522 outputs the count value to the random value storage circuit 531 based on the count value input from the count value permutation changing circuit 523. When the counter 521 updates the count value to the final value (“49” in this example), the counter 521 outputs a notification signal to the CPU 56. When the notification signal is output, the initial value of the count value of the counter 521 is changed again by the CPU 56.

  By repeating the operation as described above, the comparator 522 causes the counter 521 to continuously count up the count value from “0” to the maximum random number “256”, and the value from “0” to “256”. Is stored in the random value storage circuit 531 as a random R (random number value). In other words, the comparator 522 limits the update range of the count value to the random number maximum value “256” or less, and causes the counter 521 to update the count value.

  FIG. 11 is an explanatory diagram showing an example of the random number maximum value setting register 535. FIG. 11A shows an example of the random number maximum value setting register 535 installed in the 12-bit random number circuit 503a. FIG. 11B shows an example of the random number maximum value setting register 535 installed in the 16-bit random number circuit 503b. First, the random number maximum value setting register 535 mounted in the 12-bit random number circuit 503a will be described. As shown in FIG. 11A, in the 12-bit random number circuit 503a, the random number maximum value setting register 535 is a 16-bit register, and the initial value is set to “4095 (= 0FFFh)”. The random number maximum value setting register 535 is configured so that bits 0 to 11 can be written and read. In addition, the random number maximum value setting register 535 is configured such that bits 12 to 15 cannot be written or read. Therefore, in the 12-bit random number circuit 503a, even if control is performed to write values to bits 12 to 15 of the random number maximum value setting register 535, the values read from bits 12 to 15 are all “0 (= 0000b)”. Is.

  The random number maximum value set in the random number maximum value setting register 535 has a predetermined lower limit value. In this embodiment, when random number maximum value setting data “0000h” to “00FEh” designating a value smaller than the lower limit value “256” is written in the random number maximum value setting register 535, the CPU 56 stores the random number maximum value setting register. The random number maximum value setting data “0FFFh” for specifying the initial value “4095” is set again in 535. That is, the random number maximum value that can be set in the random number maximum value setting register 535 is from “256” to “4095”, and when the CPU 56 determines that a value smaller than the lower limit value “256” is set, the random number maximum value Is reset to a predetermined value “4095”. The CPU 56 controls the random number maximum value setting register 535 in which the random number maximum value setting data is written to be unwritable until the game control microcomputer 560 is system-reset by the reset controller 502.

  Next, the random number maximum value setting register 535 mounted in the 16-bit random number circuit 503b will be described. As shown in FIG. 11B, in the 16-bit random number circuit 503b, the random number maximum value setting register 535 is a 16-bit register, and the initial value is set to “65535 (= FFFFh)”. Further, in the 16-bit random number circuit 503b, the random number maximum value setting register 535 is configured in a state in which all of the bits 0 to 15 can be written and read.

  When random number maximum value setting data “0000h” to “00FEh” for designating a value smaller than the lower limit value “256” is written in the random number maximum value setting register 535, the CPU 56 stores the initial value in the random number maximum value setting register 535 in the initial value. The random number maximum value setting data “FFFFh” specifying the value “65535” is reset. That is, the random number maximum value that can be set in the random number maximum value setting register 535 is from “256” to “65535”, and when the CPU 56 determines that a value smaller than the lower limit value “256” is set, the random number maximum value Is reset to a predetermined value “65535”. The CPU 56 controls the random number maximum value setting register 535 in which the random number maximum value setting data is written to be unwritable until the game control microcomputer 560 is system-reset by the reset controller 502.

  The clock signal output circuit 524 includes a cycle setting register (RPS) 537 for storing cycle setting data for designating the cycle of the clock signal output to the selector 528 and the inverting circuit 532 (that is, the count value update cycle). The clock signal output circuit 524 divides the reference clock signal CLK input from the clock circuit 501 mounted on the game control microcomputer 560 based on the cycle setting data stored in the cycle setting register 537, and generates a random number circuit. A clock signal (random number generating clock signal SI1) used to generate a random number value is generated inside 503. By doing so, the clock signal output circuit 524 operates to output the random number generation clock signal SI1 for updating the count value C to the counter 521 on condition that the clock signal has been input a predetermined number of times. . The period setting data is data for setting how many times the reference clock signal CLK input from the clock circuit 501 is to be divided. The clock output circuit 524 outputs the generated random number generating clock signal SI1 to the selector 528 and the inverting circuit 532. For example, when the cycle setting data “0Fh (= 16)” is written in the cycle setting register 537, the clock signal output circuit 524 divides the reference clock signal CLK input from the clock circuit 501 by 16, and generates random numbers. A clock signal SI1 is generated. In this case, the cycle of the random number generating clock signal SI1 generated by the clock signal output circuit 524 is “cycle of system clock signal × 128 × 16”.

  FIG. 12 is an explanatory diagram showing an example of the cycle setting register 537. As shown in FIG. 12, the period setting register 537 is an 8-bit register, and the initial value is set to “256 (= FFh)”. The cycle setting register 537 is configured in a state where both writing and reading are possible.

  In addition, a predetermined lower limit value is set for the value of the cycle setting data set in the cycle setting register 537. In this embodiment, when the cycle setting data “00h to 06h” designating a value smaller than the lower limit value “system clock signal cycle × 128 × 7” is written in the cycle setting register 537, the CPU 56 In 537, the cycle setting data “07h” for specifying the lower limit value “cycle of system clock signal × 128 × 7” is reset. That is, the period that can be set in the period setting register 537 is from “system clock signal period × 128 × 7” to “system clock signal period × 128 × 256”, and the CPU 56 is set to a value smaller than the lower limit value. If it is determined that it is, the cycle setting data is reset. The CPU 56 controls the period setting register 537 in which the period setting data is written to be unwritable until the game control microcomputer 560 is system reset by the reset controller 502.

  Note that the clock signal output circuit 524 may output the reference clock signal CLK to the counter 521 and the inverting circuit 532 without setting the period setting data in the period setting register 537. In this case, the CPU 56 does not need to perform processing for setting the value of the cycle setting data set in the cycle setting register 537 by comparing it with the lower limit value. Further, the counter 521 updates the count value C every time the reference clock signal CLK is input from the clock signal output circuit 524.

  The count value update signal output circuit 525 includes a count value update register (RGN) 538 that stores count value update data “01h”. The count value update data is data for requesting update of the count value. The count value update signal output circuit 525 outputs the count value update signal SI3 to the selector 528 in response to the count value update data “01h” being written in the count value update register 538.

  FIG. 13 is an explanatory diagram illustrating an example of the count value update register 538. As shown in FIG. 13, the count value update register 538 is an unreadable 8-bit register, and is configured in a state where only bit 0 can be written. Therefore, even if control is performed to write a value to bits 1 to 7 of the count value update register 538, it is invalidated.

  The random value read signal output circuit 526 includes a random value take-in register (RLT) 539 for storing random value take-in data “01h”. The random value acquisition data is data for requesting acquisition of the count value to the random value storage circuit 531. The random value read signal output circuit 526 generates a latch value read signal for requesting reading of the random value in response to the random value take-in data “01h” being written in the random value take-in register 539. Output to the circuit 533.

  FIG. 14 is an explanatory diagram showing an example of the random value fetch register 539. As shown in FIG. 14, the random value fetch register 539 is an unreadable 8-bit register. The random value fetch register 539 is configured so that only bit 0 can be written. In other words, even if control is performed to write a value to bits 1 to 7 of the random value fetch register 539, it is invalidated.

  The random number update method selection signal output circuit 527 includes a random number update method selection register (RTS) 540 that stores random number update method selection data. The random number update method selection data is data for designating one of the random number update methods, which is a method for updating the value of the random R. The random number update method selection signal output circuit 527 responds to the random number update method selection data written in the random number update method selection register 540, and corresponds to the random number update method specified by the written random number update method selection data. The update method selection signal is output to the selector 528 and the latch signal generation circuit 533.

  FIG. 15A is an explanatory diagram illustrating an example of the random number update method selection register 540. As shown in FIG. 15A, the random number update method selection register 540 is an 8-bit register, and the initial value is set to “00h”. The random number update method selection register 540 is configured in a state where bits 0 to 1 can be written and read. The random number update method selection register 540 is configured in a state where bits 2 to 7 cannot be written or read. Therefore, even if control is performed to write a value to bits 2 to 7 of the random number update method selection register 540, it is invalid, and all the values read from bits 2 to 7 are “0 (= 000000b)”.

  FIG. 15B is an explanatory diagram of an example of random number update method selection data written to the random number update method selection register 540. As shown in FIG. 15B, the random number update method selection data is composed of 2-bit data. The random number update method selection data “01b” is used to specify the first random number update method. The random number update method selection data “10b” is used to specify the second random number update method. In this embodiment, the first random number update method is a method of updating the count value triggered by the output of the count value update signal SI3 from the count value update signal output circuit 525. The second random number update method is a method of updating the count value triggered by the output of the random number generation clock signal SI1 from the clock signal output circuit 524. Further, when the random number update method selection data “01b” or “10b” is written in the random number update method selection register 540, the random number circuit 503 is ready to be activated. On the other hand, when the random number update method selection data “00b” or “11b” is written in the random number update method selection register 540, the random number circuit 503 cannot be activated.

  The selector 528 selects either the count value update signal SI 3 output from the count value update signal output circuit 525 or the random number generation clock signal SI 1 output from the clock signal output circuit 524 and outputs the selected signal to the counter 521. When a random number update method selection signal (also referred to as a first random number update method selection signal) corresponding to the first random number update method is input from the random number update method selection signal output circuit 527, the selector 528 outputs a count value update signal. The count value update signal SI3 output from the circuit 525 is selected and output to the counter 521. On the other hand, when a random number update method selection signal (also referred to as a second random number update method selection signal) corresponding to the second random number update method is input from the random number update method selection signal output circuit 527, the selector 528 outputs a clock signal. The random number generation clock signal SI 1 output from the circuit 524 is selected and output to the counter 521. When the first update method selection signal is input from the random number update method selection signal output circuit 527, the selector 528 receives a clock signal according to the count value update signal SI3 output from the count value update signal output circuit 525. A numerical value update instruction signal for instructing update of numerical data synchronized with the random number generation clock signal SI 1 output from the output circuit 524 may be output to the counter 521.

  The random number circuit activation signal output circuit 530 includes a random number circuit activation register (RST) 541 that stores random number circuit activation data “80h”. The random circuit activation data is data for requesting activation of the random number circuit 503. When random number circuit activation data “80h” is written to the random number circuit activation register 541, the random number circuit activation signal output circuit 530 outputs a predetermined random number circuit activation signal to the counter 521 and the clock signal output circuit 537, and the counter 521 and the clock The signal output circuit 524 is turned on. The random number circuit 503 is activated by starting the count value updating operation by the counter 521 and the internal clock signal output operation by the clock signal output circuit 524.

  FIG. 16 is an explanatory diagram showing an example of the random number circuit activation register 541. As shown in FIG. 16, the random number circuit activation register 541 is an 8-bit register, and the initial value is set to “00h”. The random number circuit activation register 541 is configured such that only bit 7 can be written and read. In addition, the random number circuit activation register 541 is configured such that bits 0 to 6 cannot be written or read. That is, even if control is performed to write a value to bits 0 to 6 of the random number circuit activation register 541, it is invalid, and all values read from bits 0 to 6 are “0 (= 000000b)”.

  The random value storage circuit 531 is a 16-bit register, for example, and stores a random R value that is a random number used in the jackpot determination in the game control process. The random value storage circuit 531 stores the count value C output from the counter 521 via the comparator 522 as a random R value in response to the input of the latch signal SL from the latch signal generation circuit 533. Each time the latch signal SL is input from the latch signal generation circuit 533, the random value storage circuit 531 reads the count value C updated by the counter 521 and stores the random R value.

  FIG. 17 is a circuit diagram showing a configuration example of the random value storage circuit 531. As shown in FIG. 17, the random value storage circuit 531 includes two AND circuits 201 and 203, two NOT circuits 202 and 204, 16 flip-flop circuits 2101 to 2116, and 16 OR circuits. 2201-2216.

  As shown in FIG. 17, the input terminal of the AND circuit 201 is connected to the output terminal of the latch signal generation circuit 533 and the output terminal of the NOT circuit 204, and the output terminal is connected to the input terminal of the NOT circuit 202 and the flip-flop circuit 2101. Are connected to clock terminals Clk1 to Clk16. The input terminal of the NOT circuit 202 is connected to the output terminal of the AND circuit 201, and the output terminal is connected to one input terminal of the AND circuit 203.

  The input terminal of the AND circuit 203 is connected to the output terminal of the NOT circuit 202 and the CPU 56 mounted on the game control microcomputer 560, and the output terminal is connected to the input terminal of the NOT circuit 204. The input terminal of the NOT circuit 204 is connected to the output terminal of the AND circuit 203, and the output terminal is connected to one input terminal of the AND circuit 201 and one input terminal of the OR circuits 2201 to 2216.

  The input terminals D1 to D16 of the flip-flop circuits 2101 to 2116 are connected to the output terminal of the comparator 522. The clock terminals Clk1 to Clk16 of the flip-flop circuits 2101 to 2116 are connected to the output terminal of the AND circuit 201, and the output terminals Q1 to Q16 are connected to the other input terminals of the OR circuits 2201 to 2216.

  The input terminals of the OR circuits 2201 to 2216 are connected to the output terminal of the NOT circuit 204 and the output terminals of the flip-flop circuits 2101 to 2116, and the output terminals are connected to the CPU 56 mounted on the game control microcomputer 560. .

  The operation of the random value storage circuit 531 will be described. FIG. 18 is a timing chart showing the timing at which each signal is input to the random value storage circuit 531 and the timing at which the random value storage circuit 531 outputs each signal. As shown in FIG. 18, when the output control signal SC (high level signal in this example) is not input from the CPU 56 mounted on the game control microcomputer 560 (that is, to one input terminal of the AND circuit 203). When the latch signal SL is input from the latch signal generation circuit 533 (when the input is at a low level) (at the timings T1, T2, and T7 in the example illustrated in FIG. 18), the input to the two input terminals of the AND circuit 201 is performed. Both inputs are high. Therefore, the signal SR output from the output terminal of the AND circuit 201 is at a high level. The signal SR output from the AND circuit 201 is input to the clock terminals Clk1 to Clk16 of the flip-flop circuits 2101 to 2116.

  The flip-flop circuits 2101 to 2116 are responsive to the rising edges of the signal SR input from the clock terminals Clk1 to Clk16, and the bit data C1 to C1 of the count value C input from the comparator 522 via the input terminals D1 to D16. C16 is latched and stored as bit data R1 to R16 of the random value. The flip-flop circuits 2101 to 2116 output random R bit data R1 to R16 to be stored from the output terminals Q1 to Q16.

  When the output control signal SC is not input (in the example shown in FIG. 18, the period up to the timing T3 and the period after the timing T6), the input to one input terminal of the AND circuit 203 is at the low level. The signal SG output from the output terminal of the circuit 203 is at a low level. The signal SG output from the AND circuit 203 is inverted by the NOT circuit 204 to be a high level signal. A high level signal is input from the NOT circuit 204 to one input terminal of each of the OR circuits 2201 to 2216.

  As described above, since the input to one of the input terminals of the OR circuits 2201 to 2216 is at a high level, the OR is input regardless of whether the signal input to the other input terminal is at a high level or a low level. The circuits 2201 to 2216 output high level signals. That is, the signals SO1 to SO16 output from the OR circuits 2201 to 2216 are all at a high level regardless of whether the values of the input random R bit data R1 to R16 are “0” or “1”. (“1”). By doing so, the value output from the random value storage circuit 531 is always “65535 (= 1111111111111111b)”, and the random R cannot be read from the random value storage circuit 531. That is, even if an attempt is made to read a random number from the random value storage circuit 531, only the same value “65535” can always be read from the random value storage circuit 531, and when the output control signal SC is not input, the random value storage circuit 531 is in an unreadable (disabled) state. When the 16-bit random number circuit 503b is used, the value “65535” as the random number value may be used. In this case, even if the game control microcomputer 560 reads the value “65535”, it cannot determine whether the value is a random number or an unreadable state. Therefore, in the determination table for each jackpot determination shown in FIG. 27, when the random R is “65535”, it may be set to determine “lost” in advance.

  When the output control signal SC is input from the CPU 56 when the latch signal SL is not input from the latch signal generation circuit 533 (in the example shown in FIG. 18, the period from the timing T4 to the timing T6), Since the inputs to the two input terminals are both at the high level, the signal SG output from the output terminal of the AND circuit 203 is at the high level. The signal SG output from the AND circuit 203 is inverted in the NOT circuit 204 to be a low level signal. A low level signal is input from the NOT circuit 204 to one input terminal of the OR circuits 2201 to 2216.

  As described above, since the input to one input terminal of the OR circuits 2201 to 2216 is at a low level, when the signal input to the other input terminal is at a high level, the output from the output terminals of the OR circuits 2201 to 2216 is high. A level signal is output. In addition, when a signal input to the other input terminal of the OR circuits 2201 to 2216 is at a low level, a low level signal is output from the OR circuits 2201 to 2216. That is, the values of the random R bit data R1 to R16 input to the other input terminals of the OR circuits 2201 to 2216 are unchanged from the output terminals of the OR circuits 2201 to 2216 (that is, the values of the bit data R1 to R16 are “ “1” is output when it is “1” and “0” when it is “0”). By doing so, random R can be read from the random value storage circuit 531. That is, when the output control signal SC is input, the random value storage circuit 531 is in a readable (enable) state.

  However, if the latch signal SL is input from the latch signal generation circuit 533 before the output control signal SC is input from the CPU 56, the input to one input terminal of the AND circuit 203 is at a low level. Even if the output control signal SC is input while the signal SL is being input (in the example shown in FIG. 18, the period from the timing T3 to the timing T4), the signal SG output from the output terminal of the AND circuit 203. Remains low. The signal SG output from the AND circuit 203 is inverted by the NOT circuit 204 to be a high level signal. A high level signal is input from the NOT circuit 204 to one input terminal of each of the OR circuits 2201 to 2216.

  As described above, since the input to one of the input terminals of the OR circuits 2201 to 2216 is at the high level, the OR is input regardless of whether the signal input to the other input terminal is at the high level or the low level. All of the signals SO1 to SO16 output from the circuits 2201 to 2216 are at a high level. Even though the output control signal SC is input, the random R cannot be read from the random value storage circuit 531. That is, when the latch signal SL is input, the random value storage circuit 531 cannot receive the output control signal SC. When the 16-bit random number circuit 503b is used, the value “65535” as the random number value may be used. In this case, even if the game control microcomputer 560 reads the value “65535”, it cannot determine whether the value is a random number or an unreadable state. Therefore, in the determination table for each jackpot determination shown in FIG. 27, when the random R is “65535”, it may be set to determine “lost” in advance.

  Further, when the output control signal SC is input from the CPU 56 before the latch signal SL is input from the latch signal generation circuit 533, the input to one input terminal of the AND circuit 201 is at a low level. Even if the latch signal SL is input while the control signal SC is being input (timing T5 in the example shown in FIG. 18), the signal SR output from the output terminal of the AND circuit 201 remains at the low level. It becomes. Therefore, the signal SR input to the clock terminals Clk1 to Clk16 of the flip-flop circuits 2101 to 2116 does not rise from the low level to the high level, and the random R bit data R1 to R16 stored in the flip-flop circuits 2101 to 2116. Is not updated despite the latch signal SL being input. That is, when the output control signal SC is input, the random value storage circuit 531 cannot receive the latch signal SL.

  The inverting circuit 532 generates the inverted clock signal SI2 in which the polarity of the clock signal is inverted by inverting the signal level in the random number generating clock signal SI1 input from the clock signal output circuit 524. Further, the inverting circuit 532 outputs the generated inverted clock signal SI2 to the latch signal generating circuit 533.

  The latch signal generation circuit 533 is configured using a selector, a flip-flop circuit, and the like. The latch signal generation circuit 533 receives the random number read signal from the random number read signal output circuit 526 and the inverted clock signal SI2 from the inversion circuit 532, and stores the random value in the random value storage circuit 531. Output SL. The latch signal generation circuit 533 outputs the latch signal SL in accordance with the random value update method designated by the random number update method selection signal from the random number update method selection signal output circuit 527. In this case, when the first random number update method selection signal output circuit 527 receives the first random number update method selection signal output circuit 527, the latch signal generation circuit 533 selects the inverted clock signal SI2 output from the inversion circuit 532, and the latch signal It outputs to the random value storage circuit 531 as SL. On the other hand, when the second random number update method selection signal is input from the random number update method selection signal output circuit 527, the latch signal generation circuit 533 inverts the random value read signal output from the random value read signal output circuit 526. In synchronization with the rising edge of the inverted clock signal SI2 output from the circuit 532, the latch signal SL is output to the random value storage circuit 531.

  The timer circuit 534 inputs a winning detection signal SS indicating that a winning of a game ball to the starting port 14 has been detected from the starting port switch 14a. The timer circuit 534 measures the time during which the winning detection signal SS is continuously input from the start port switch 14a. Then, when the measurement time reaches a predetermined period (for example, 3 ms), the timer circuit 534 writes the random number value capture data “01h” in the random value capture register 539 of the random value read signal output circuit 526. For example, the timer circuit 534 is configured by an up counter or a down counter that is activated in response to the input of a high level signal. The timer circuit 534 receives the reference clock signal CLK sequentially input from the clock circuit 501 while the input from the start port switch 14a is at a high level (that is, while the winning detection signal SS is continuously input). Count up or down. Then, when the count value to be counted up or down reaches a value corresponding to 3 ms, the timer circuit 534 determines that the winning detection signal SS is input from the start port switch 14a, and stores the random number value capture data “01h”. Write to the random value fetch register 539.

  FIG. 19 is an explanatory diagram showing an example of an address map of a storage area in the game control microcomputer 560. As shown in FIG. 19, the area from address 0000h to address 1FFFh in the storage area of the game control microcomputer 560 is allocated to the ROM 54. An area from addresses 7E00h to 7FFFh is allocated to the RAM 55. Further, the area from the address FD00h to the address FE00h is allocated to a built-in register such as the random number maximum value setting register 535.

  As shown in FIG. 19, the area from address 0000h to address 1FFFh allocated to the ROM 54 includes a user program area and a user program management area. A program (user program) 550 created in advance by a user (for example, a game machine manufacturer) is stored in the user program area in the area of addresses 0000h to 1F7Fh. Further, data (user program execution data) necessary for the CPU 56 to execute the user program 550 is stored in the user program management area in the area of addresses 1F80h to 1FFFh. Of the areas 7E00h to 7FFFh allocated to the RAM 55, the areas 7E00h to 7EFFh are unused areas, and the areas 7EFFh to 7FFFh are used as work areas.

  FIG. 20 is an explanatory diagram showing an example of an address map in the user program management area. As shown in FIG. 20, in the area of address 1F97h, among the initial value changing methods that are methods for changing the initial value input to the counter 521, the initial value changing method selected by the user is designated. The initial value change method setting data is stored. In addition, in the areas 1F98h and 1F99h, RAM address data for specifying an address (designated RAM address) in the RAM 55 designated in advance by the user among addresses 7EFFh to 7FFFh allocated to the RAM 55 is stored. The In this case, of the values indicating the designated RAM address, the lower value of the designated RAM address is stored in the 1F98h address, and the higher value of the designated RAM address is stored in the 1F99h address.

  FIG. 21 is an explanatory diagram of an example of initial value change method setting data. As shown in FIG. 21, the initial value change data is composed of 8-bit data. The initial value change data “00h” is data specifying that the initial value is not changed as the initial value change method. In this embodiment, when the initial value change data “00h” is set, the counter 521 of the random number circuit 503 updates the count value from a predetermined initial value “0” to a predetermined final value. Become. Further, the initial value change data “01h” is data specifying that the initial value input to the counter 521 is changed to a value based on an ID number for identifying the game control microcomputer 560 as an initial value change method. It is. In this embodiment, when the initial value change data “01h” is set, the initial value of the counter value updated by the counter 521 is changed from “0” to a value based on the ID number. The count value is updated from the initial value to a predetermined final value.

  The user program 550 stored in the user program area will be described. FIG. 22 is an explanatory diagram showing a configuration example of the user program 550. As shown in FIG. 22, in this embodiment, the user program 550 includes a random number circuit setting program 551 composed of a plurality of types of program modules, a display result determination program 552, a count value permutation change program 554, And a numerical value update program 555.

  The random number circuit setting program 551 is a program for causing the random number circuit 503 to execute a random number circuit setting process for performing an initial setting for updating the random R value. That is, the CPU 56 functions as random number circuit setting means by executing processing according to the random number circuit setting program 551.

  FIG. 23 is an explanatory diagram showing a configuration example of the random number circuit setting program 551. As shown in FIG. 23, the random number circuit setting program 551 includes a random number maximum value setting module 551a, a random number update method selection module 551b, a cycle setting module 551c, a random number circuit activation module 551d, as a plurality of types of program modules. An initial value changing module 551e and a random number circuit selecting module 551f are included.

  The random number maximum value setting module 551a is a program module for causing the random number circuit 503 to set the maximum value of the random R preset by the user (for example, the manufacturer of the gaming machine). The CPU 56 executes processing according to the random number maximum value setting module 551a, thereby writing random number maximum value setting data for specifying the maximum value of the random R preset by the user in the random number maximum value setting register 535. By doing so, the CPU 56 sets the maximum value of the random R preset by the user in the random number circuit 503. For example, when “255” is set in advance as the maximum value of the random R by the user, the CPU 56 writes the random number maximum value setting data “00FFh” in the random number maximum value setting register 535 and the maximum value of the random R “255”. Is set in the random number circuit 503.

  The random number update method selection module 551b is a program module for causing the random number circuit 503 to set the random number update method (first random number update method or second random number update method) selected by the user. The CPU 56 writes the random number update method selection data “01b” or “10b” designating the random number update method selected by the user in the random number update method selection register 540 by executing the process according to the random number update method selection module 551b. By doing so, the CPU 56 sets the random number update method selected by the user in the random number circuit 503. Therefore, the game control microcomputer 560 has a function of selecting either the first random number update method or the second random number update method as the random number update method used by the random number circuit 503 for the random number update.

  The cycle setting module 551c is a program for causing the random number circuit 503 to set the cycle of the internal clock signal preset by the user (that is, the cycle in which the clock signal output circuit 524 outputs the clock signal to the selector 528 and the inverting circuit 532). It is a module. The CPU 56 writes the period setting data for designating the period of the internal clock signal preset by the user in the period setting register 537 by executing the process according to the period setting module 551c. By doing so, the CPU 56 sets the cycle of the internal clock signal preset by the user in the random number circuit 503. For example, when the cycle of the internal clock signal is set in advance as “system clock signal cycle × 128 × 16” by the user, the CPU 56 writes the cycle setting data “0Fh” in the cycle setting register 537 and sets the internal clock signal The period “system clock signal period × 128 × 16” is set in the random number circuit 503.

  The random number circuit activation module 551d is a program module for activating the random number circuit 503. The CPU 56 activates the random number circuit 503 by writing the random number circuit activation data “80h” to the random number circuit activation register 541 by executing processing according to the random number circuit activation module 551d.

  The initial value change module 551e is a program module for changing the initial value of the count value updated by the counter 521. The CPU 56 functions as an initial value changing unit by executing processing according to the initial value changing module 551e. The CPU 56 executes the initial value changing module 551e to change the initial value of the count value updated by the counter 521 by the initial value changing method selected by the user. By doing so, the game control microcomputer 560 has a function of selecting an initial value changing method.

  In this embodiment, when initial value change method setting data “01h” is stored in the area of address 1F97h in the user program management area, the CPU 56 sets the initial value of the count value for each game control microcomputer 560. The value is changed to a value calculated based on the assigned unique ID number.

  For example, the game control microcomputer 560 associates, in a predetermined storage area of the RAM 55, the ID number of the game control microcomputer 560 with a calculation value obtained by performing a predetermined calculation based on the ID number. I remember it. In this case, for example, if the ID number of the game control microcomputer 560 is “100”, the calculated value “150” obtained by adding the predetermined value “50” to the ID number “100” is set in advance as the ID number. Are stored in association with each other. Further, for example, the calculated value “50” obtained by subtracting the predetermined value “50” from the ID number “100” is stored in advance in association with the ID number. Further, for example, only a predetermined value may be stored in advance in association with the ID number. Then, the game control microcomputer 560 uses a value “150” obtained by adding an ID number (for example, “100”) to a predetermined value (for example, “50”) stored in advance as an initial value of the count value. In addition, the game control microcomputer 560 uses a value “50” obtained by subtracting a predetermined value (for example, “50”) stored in advance from the ID number (for example, “100”) as the initial count value. It may be a value.

  When the initial value change method setting data “01h” is stored, the CPU 56 changes the initial value of the count value to the calculated value based on the ID number stored in advance. By doing so, the randomness of the random number generated by the random number circuit 503 can be further improved, and the initial value of the random number can be made difficult to recognize only by looking at the ID number of the game control microcomputer 560. . Therefore, it is possible to more reliably prevent the transition condition to the big hit state from being illegally established by an action such as generating a captured signal using a radio signal to the gaming machine, and improving security. Can be improved.

  For example, when initial value change method setting data “01h” is stored, the CPU 56 calculates the ID number of the game control microcomputer 560 and a predetermined value (for example, adds the predetermined value to the ID number). The initial value of the count value is changed to the calculated value obtained. In this case, for example, the CPU 56 may calculate a value that is randomly changed using a random number as an ID number, thereby randomly updating a value used for the calculation and obtaining an initial value. By doing so, the randomness of the random numbers generated by the random number circuit 503 can be further improved.

  The random number circuit selection module 551f is a program module for setting a random number circuit to be used when executing a timer interrupt process including a game control process from among the random number circuits 503 built in the game control microcomputer 560. The CPU 56 executes a process according to the random number circuit selection module 551f, so that any of the two random number circuits (12-bit random number circuit 503a and 16-bit random number circuit 503b) built in the game control microcomputer 560 is selected. Set whether to use when executing timer interrupt processing. For example, the CPU 56 uses a 12-bit random number circuit 503a or 16-bit as a random number circuit used when executing the timer interrupt process according to a predetermined set value (a value set in advance by the user) stored in a predetermined storage area of the RAM 55. The random number circuit 503b is set.

  Note that both the 12-bit random number circuit 503a and the 16-bit random number circuit 503b may be set as random number circuits used when the timer interrupt process is executed. In this case, for example, the game control microcomputer may perform a jackpot determination based on a random number generated by the 12-bit random number circuit 503a and may perform a probability change determination based on the random number generated by the 16-bit random number circuit 503b. . In this embodiment, the random value storage circuit 531 is present in each of the 12-bit random number circuit 503a and the 16-bit random number circuit 503b (that is, a random number storage circuit that stores a random number for 12 bits and a random number for 16 bits). And a random number storage circuit for storing the same). When both the 12-bit random number circuit 503a and the 16-bit random number circuit 503b are set, the game control microcomputer 560 outputs the random number read from the 12-bit random number circuit 503a and the random number read from the 16-bit random number circuit 503b. , And stored in separate buffer areas provided in the RAM 55. Therefore, even when the timing for reading a random number from the 12-bit random number circuit 503a and the timing for reading a random number from the 16-bit random number circuit 503b are the same, two different random numbers can be extracted and stored in different buffer areas.

  The random value update program 555 is a program for updating the value of the random R stored in the random value storage circuit 531 when the first random number update method is selected as the random number update method. The CPU 56 functions as a random value updating means by executing processing according to the random value updating program 555. When the first random number update method is selected, the CPU 56 executes the random number value update program 555 and writes the count value update data “01h” in the count value update register 538, whereby the count value is stored in the counter 521. And the value of the random R stored in the random value storage circuit 531 is updated. When the second random number update method is selected as the random number update method, the counter 521 is updated with the random number generation clock signal output from the clock signal output circuit 537, and the random value storage circuit 531 is updated. The value of random R stored in is updated.

  The display result determination program 552 is a program for determining whether or not the display result in the special symbol display device 8 is a jackpot symbol. The CPU 56 functions as a display result determination unit by executing processing according to the display result determination program 552.

  In this embodiment, the CPU 56 follows the display result determination program 552 in response to the fact that the game ball has won the variable winning ball device 15 and a condition (execution condition) for executing the variable symbol variable display is established. Execute the process. Then, the CPU 56 reads the updated random R value from the random value storage circuit 531 and determines whether or not the display result in the special symbol display device 8 is a jackpot symbol.

  FIG. 24 is an explanatory diagram illustrating an operation in which the CPU 56 updates the random R value or reads the random R value when the first random number update method is selected. As shown in FIG. 24, when the first random number update method is selected, the CPU 56 writes the count value update data “01h” into the count value update register 538, thereby storing the random value stored in the random value storage circuit 531. The value of R (for example, “2”) is updated. Then, the CPU 56 receives the random R value from the random value storage circuit 531 in response to the fact that the game ball has won the variable winning ball device 15 and the condition (execution condition) for executing the variable symbol special display is established. (For example, “2”) is read out.

  When the random R value stored in the random value storage circuit 531 is further updated, an interval equal to or longer than the cycle of the system clock signal output from the clock circuit 501 has elapsed since the random R value was updated during the previous update. Sometimes, the count value update data “01h” must be written to the count value update register 538. This is because it is necessary to secure time for reading the updated random R value from the random value storage circuit 531.

  FIG. 25 is an explanatory diagram illustrating an operation in which the CPU 56 updates the random R value or reads the random R value when the second random number update method is selected. As shown in FIG. 25, when the second random number update method is selected, the CPU 56 writes the random value fetch command “01h” into the random value fetch register 539, thereby outputting the count value output by the counter 521. (For example, “2”) is taken into the random value storage circuit 531 to update the random R value stored in the random value storage circuit 531. Then, the CPU 56 reads the updated random R value (for example, “2”) from the random value storage circuit 531.

  Specifically, when the second random number update method is selected, the counter 521 updates the count value C using the input of the random number generation clock signal SI1 as a trigger. Thereafter, when the random value acquisition command “01h” is written in the random value acquisition register 539, the latch signal generation circuit 533 outputs the latch signal SL to the random value storage circuit 531. Then, the random value storage circuit 531 reads and stores the count value output from the counter 521 with the input of the latch signal SL as a trigger. Then, the CPU 56 reads the value of random R stored in the random value storage circuit 531.

  If the CPU 56 does not write the random value acquisition command “01h” to the random value acquisition register 539, even if the counter 521 updates the count value, the random value storage circuit 531 stores the random value that the counter 521 updates. Do not read. For example, the CPU 56 writes the random value acquisition command “01h” into the random value acquisition register 539, causes the count value “3” output from the counter 521 to be acquired into the random value storage circuit 531, and the random value storage circuit 531 stores it. Assume that the random R value “3” is updated. In this case, if the CPU 56 does not write the random number value capture command “01h” again in the random number capture register 539, the count value output from the counter 521 is updated from “3” to “4” or “5”. The random value stored in the random value storage circuit 531 is not updated, and the random value read from the random value storage circuit 531 remains “3”.

  The count value permutation change program 554 writes count value permutation change data “01h” to the count value permutation change register 536, and executes count value permutation change processing for changing the permutation of count values stored in the random value storage circuit 531. It is a program for. The CPU 56 functions as numerical data permutation changing means by executing processing according to the count value permutation changing program 554. The CPU 56 executes the count value permutation change program 554 and writes the count value permutation change data “01h” in the count value permutation change register 536, whereby the count value permutation change circuit 523 outputs and inputs to the random value storage circuit 531. The permutation of the count values to be changed.

  Further, as shown in FIG. 26, the game control microcomputer 560 includes a special figure holding memory 570, a big hit determination table memory 571, a flag memory 572, and a start winning port switch timer memory 573.

  In the special figure holding memory 570, the game ball wins the variable winning ball device 15 and the execution condition of the variable symbol variable display is satisfied, but the variable display start condition is not yet satisfied (for example, the special symbol display device). 8 is a memory for storing pending data including the number of times the execution condition of variable display is satisfied (8 is still executing variable display). The special figure holding memory 570 includes four entries. Each entry includes a holding number and a random R read from the random number storage circuit 531 according to the winning order in the order in which the game balls win the variable winning ball device 15. A value is stored in association with each other. In addition, each time the special symbol variable display in the special symbol display device 8 is finished once or the big hit gaming state is finished, the variable display start condition based on the top information of the special symbol holding memory 570 is set. It is established, and variable display based on the top information of the special figure holding memory 570 is executed. In this case, when the condition for starting the variable display of special symbols is satisfied, the information registered in the second or lower place in the special figure holding memory 570 is moved up by one place. In addition, when a game ball newly wins the variable winning ball apparatus 15 during the variable display of the special symbol, the value of the random R read from the random value storage circuit 531 based on the new winning is the special R value. It is registered in the empty entry in the figure holding memory 570.

  The jackpot determination table memory 571 stores a plurality of jackpot determination tables used by the CPU 56 to determine whether or not the display result of the special symbol display device 8 is a jackpot symbol. Specifically, as shown in FIG. 27A, the big hit determination table memory 571 stores a normal time big hit determination table 571a used in a gaming state (referred to as a normal state) other than the probability variation state. Further, as shown in FIG. 27B, the jackpot determination table memory 571 stores a probability change big hit determination table 571b used in the probability change state. When the big hit determination is performed using the determination table shown in FIG. 27, the probability of determining a big hit depends on the random number maximum value set in the random number maximum value setting register 535. In this case, for example, if the set random number maximum value is too small, the difference in the probability of determining a big hit between the case where the normal big hit determination table 571a is used and the case where the probability variation big hit determination table 571b is used is small. As a result, the player's interest in the game is diminished. Therefore, a plurality of determination tables (a plurality of normal time big hit determination tables 571a and a plurality of probability variation big hit determination tables 571b) are stored in the big hit determination table memory 571 in association with the random number circuit 503 and the random number maximum value. Also good. Then, the game control microcomputer 560 uses the random number circuit 503 to be used and the determination tables 571a and 571b corresponding to the maximum random number among the determination tables stored in the jackpot determination table memory 571 to display the display result determination program 552. Accordingly, it may be determined whether or not the display result of the special symbol display device 8 is a jackpot symbol. By doing so, even if the type of random number circuit 503 to be used and the maximum random number value are different, it is possible to control so that the probability of determining a jackpot is the same to some extent.

  In the flag memory 572, various flags used in the game control process for controlling the progress of the game are set. For example, in the flag memory 572, a probability change flag indicating that the gaming state is a probability change state and a big hit flag indicating that the game state is a big hit state are set.

  The start port switch timer memory 573 stores a timer value that is added or cleared in accordance with the winning detection signal SS input from the start port switch 14a.

  Next, the operation of the gaming machine will be described. 28 and 29 show main processing executed by the game control microcomputer 560 in response to the start of power supply to the game machine and the reset signal to the game control microcomputer 560 becoming high level. It is a flowchart. When the input level of the reset terminal to which the reset signal is input becomes high level, the game control microcomputer 560 executes a security check process that is a process for confirming whether the contents of the program are valid, The main processing after S1 is started. In the main process, the game control microcomputer 560 first performs necessary initial settings.

  In the initial setting process, the game control microcomputer 560 first sets the interrupt prohibition (step S1). Next, an interrupt mode for maskable interrupts is set (step S2), and a stack pointer designation address is set for the stack pointer (step S3). In step S2, the address synthesized from the value (1 byte) of the specific register (I register) of the game control microcomputer 560 and the interrupt vector (1 byte: least significant bit 0) output from the built-in device is Set to the mode indicating the interrupt address. When a maskable interrupt is generated, the game control microcomputer 560 automatically sets the interrupt disabled state and saves the contents of the program counter in the stack.

  Next, the built-in device register is set (initialized) (step S4). By the processing in step S4, the CTC (counter / timer) and PIO (parallel input / output port), which are built-in devices (built-in peripheral circuits), are set (initialized).

  The game control microcomputer 560 used in this embodiment also incorporates an I / O port (PIO) and a timer / counter circuit (CTC) 504.

  Next, it is confirmed whether or not the power-off signal is in an OFF state depending on the state of bit 0 of the input port 1 (step S5). When the power supply to the gaming machine is started, the output voltage of various power sources such as the + 5V power source gradually reaches a specified value, but the power-off signal is not output by the process of step S5, that is, the high-power signal is not output. The game control microcomputer 560 can confirm that the power supply voltage is stable.

  When the power-off signal is on, the game control microcomputer 560 turns off the power-off signal again after a delay time of a predetermined period (for example, 0.1 second) (step S80). Check if it is. If the power-off signal is off, the RAM 55 is set to an accessible state (step S6), and the process proceeds to a clear signal check process.

  When the power-off signal is in the on state, software delay processing for delaying the start timing of the gaming device control processing (game control processing) for controlling the progress of the game by software may be executed. By such software delay processing, the start timing of the game control processing can be delayed as compared with the case where the software delay processing is not executed. When the delay process is executed, a situation occurs in which another control board cannot receive a command transmitted from the game control board (main board 31) with respect to another control board (for example, the payout control board 37). Can be prevented.

  Note that the game control microcomputer 560 may confirm the state of the clear signal only once via the input port 0, but may confirm the state of the clear signal a plurality of times. For example, if it is confirmed that the clear signal is off, a delay time of a predetermined time (for example, 0.1 seconds) is set, and then the clear signal is reconfirmed. If it is confirmed that the clear signal is in the ON state at that time, it is determined that the clear signal is in the ON state. Further, at this time, if it is confirmed that the clear signal is in the OFF state, after a predetermined delay time, the clear signal state may be reconfirmed. Here, the number of reconfirmations is not limited to once or twice, but may be three or more times. It is also possible to check twice and check again when the check results do not match.

  Next, the game control microcomputer 560 checks whether or not the clear switch-on flag is set (step S7). If the clear switch on flag is not set, whether or not data protection processing of the backup RAM area (for example, power supply stop processing such as addition of parity data) was performed when power supply to the gaming machine was stopped (Step S8). In this embodiment, when power supply is stopped, a process for protecting data in the backup RAM area is performed. When it is confirmed that such power supply stop processing has been performed, the game control microcomputer 560 stores the power supply stop processing, that is, the control state at the time of power supply stop. It is determined that When it is confirmed that the power supply stop process is not performed, the game control microcomputer 560 executes an initialization process.

  Whether or not the power supply stop process has been performed is determined by the value of the backup monitoring timer stored in the backup RAM area in the power supply stop process corresponding to the execution of the power supply stop process (for example, 2). ). Note that such a confirmation method is an example. For example, a flag indicating that the power supply stop process has been executed is set in the backup flag area in the power supply stop process, and the flag is set in step S8. If it is confirmed that the power supply is stopped, it may be determined that the power supply stop process has been performed.

  If it is determined that the control state at the time of stopping power supply is stored, the game control microcomputer 560 performs data check (parity check in this example) of the backup RAM area (step S9). In this embodiment, clear data (00) is set in the checksum data area, and the checksum calculation start address is set in the pointer. Also, the number of checksum calculations corresponding to the number of data to be checksum is set. Then, the exclusive OR of the contents of the checksum data area and the contents of the RAM area pointed to by the pointer is calculated. The calculation result is stored in the checksum data area, the pointer value is incremented by 1, and the checksum calculation count value is decremented by 1. The above processing is repeated until the value of the checksum calculation count becomes zero. When the value of the checksum calculation count becomes 0, the game control microcomputer 560 inverts the value of each bit of the contents of the checksum data area and uses the inverted data as a checksum.

  In the power supply stop process, a checksum is calculated by the same process as described above, and the checksum is stored in the backup RAM area. In step S9, the calculated checksum is compared with the stored checksum. When the power supply is stopped after an unexpected power failure or the like, the data in the backup RAM area should be saved, so the check result (comparison result) is normal (matched). That the check result is not normal means that the data in the backup RAM area may be different from the data when the power supply is stopped. In such a case, since the internal state cannot be returned to the state when the power supply is stopped, the initialization process (the process of steps S10 to S14) executed when the power is turned on, not when the power supply is stopped is stopped. Execute.

  If the check result is normal, the game control microcomputer 560 returns the game state restoration process for returning the internal state of the game control means and the control state of the electrical component control means such as the effect control means to the state when the power supply is stopped. I do. Specifically, the start address of the backup setting table stored in the ROM 54 is set as a pointer (step S91), and the contents of the backup setting table are sequentially set in the work area (area in the RAM 55) (step S92). ). The work area is backed up by a backup power source. In the backup setting table, initialization data for an area that may be initialized in the work area is set. As a result of the processing in steps S91 and S92, the saved contents of the work area that should not be initialized remain. The parts that should not be initialized include, for example, data indicating the gaming state before the power supply is stopped (special symbol process flag, etc.), the area where the output state of the output port is saved (output port buffer), unpaid prize balls This is the part where data indicating the number is set.

  Further, the game control microcomputer 560 sets the head address of the backup command transmission table stored in the ROM 54 as a pointer (step S93), and proceeds to step S15.

  In the initialization process, the game control microcomputer 560 first performs a RAM clear process (step S10). Note that the predetermined data may be left as it is without initializing the entire area of the RAM 55. Also, the initial address of the initialization setting table stored in the ROM 54 is set as a pointer (step S11), and the contents of the initialization setting table are sequentially set in the work area (step S12).

  Control states such as a normal symbol determination random number counter, a normal symbol determination buffer, a special symbol buffer, a total prize ball number storage buffer, a special symbol process flag, an award ball flag, an out-of-ball flag, etc. An initial value is set in a flag for selectively performing processing according to the above. In addition, a bit corresponding to the output port that outputs the connection confirmation signal in the output port buffer is set (corresponding to the ON state of the connection confirmation signal).

  The game control microcomputer 560 also sets the initial address of the initialization command transmission table stored in the ROM 54 as a pointer (step S13), and issues an initialization command for initializing the sub-board according to the contents. Processing to transmit to the sub-board is executed (step S14). As an initialization command, a command indicating an initial symbol displayed on the variable display device 9, an initialization command to the payout control board 37, or the like can be used.

  Further, the game control microcomputer 560 executes random number circuit setting processing for initial setting of the random number circuits 503a and 503b (step S15). In this case, the CPU 56 performs setting according to the random number circuit setting program 551 to make the random number circuits 503a and 503b update the value of the random R.

  The game control microcomputer 560 sets a timer interrupt setting for setting a CTC register built in the game control microcomputer 560 so that a timer interrupt is periodically taken every predetermined time (for example, 2 ms). Processing is executed (step S16). That is, a value corresponding to, for example, 2 ms is set in a predetermined register (time constant register) as an initial value. In this embodiment, it is assumed that a timer interrupt is periodically taken every 2 ms.

  When the setting of the timer interrupt is completed, the game control microcomputer 560 repeatedly executes the display random number update process (step S18). The game control microcomputer 560 disables the interrupt when the display random number update process is executed (step S17), and enters the interrupt enable state when the display random number update process ends (step S19). Note that the display random number is a random number for determining the symbol displayed on the special symbol display 8, and the display random number update processing is to update the count value of the counter for generating the display random number. It is processing.

  Note that when the display random number update process is executed, the interrupt disabled state is executed because the display random number update process is also executed in the timer interrupt process described later. This is to avoid this. That is, if a timer interrupt is generated during the process of step S18 and the count value of the counter for generating the display random number is updated during the timer interrupt process, the continuity of the count value is impaired. There is a case. However, such an inconvenience does not occur if the interrupt is prohibited during the process of step S18.

  As described above, a game clerk or the like can easily perform initial initialization by starting the power supply to the gaming machine (for example, turning on the power switch 914) while the clear switch 921 is turned on and the clear signal is output. Can be executed. That is, RAM clear or the like can be performed.

  Next, the random number circuit setting process (step S15) in the main process will be described. FIG. 30 is a flowchart showing random number circuit setting processing. In the random number circuit setting process, the CPU 56 first executes the process according to the random number circuit selection module 551f included in the random number circuit setting program 551, and from among the random number circuits 503a and 503b built in the game control microcomputer 560, A random number circuit to be used when executing the timer interrupt process including the control process is set (step S151). For example, the game control microcomputer 560 stores, in a predetermined storage area of the RAM 55, specification information for specifying the random number circuit 503 used when executing a timer interrupt process set by a user (for example, a game machine manufacturer). I remember it. Then, the CPU 56 selects either the 12-bit random number circuit 503a or the 16-bit random number circuit 503b according to the designation information stored in the predetermined storage area of the RAM 55, and uses the selected random number circuit when executing the timer interrupt process. Set as a random number circuit. Note that both the 12-bit random number circuit 503a and the 16-bit random number circuit 503b may be set as random number circuits used when the timer interrupt process is executed. In this case, for example, the game control microcomputer may perform a jackpot determination based on a random number generated by the 12-bit random number circuit 503a and may perform a probability change determination based on the random number generated by the 16-bit random number circuit 503b. .

  When the random number circuit 503 used in step S151 is set, the game control microcomputer 560 stops the operation of the counter 521 and the clock signal output circuit 524, for example, so that the counter of the random number circuit that is set not to be used is used. 521 prevents the count value C from being updated. Further, for example, the game control microcomputer 560 updates the count value C of the counter 521 of the random number circuit that is set not to be used, but the game control microcomputer 560 does not output the output control signal SC. The random number value storage circuit 531 may be controlled so as not to read the random number. Further, for example, the game control microcomputer 560 prevents the random value fetch data “01h” from being written into the random value fetch register 539 of the random number circuit that is set not to be used. Control may be performed so that the latch signal SL is not output to the random value storage circuit 531.

  As described above, by setting the random number circuit 503 to be used, by setting only the random number circuit 503 to be used, it is possible to appropriately set the range of the random number value to be generated. Further, it is possible to prevent unnecessary random numbers from being processed during the execution of the timer interrupt process, and the control burden on the game control microcomputer 560 can be reduced. For example, when a big hit determination is performed using a determination table including a distant value (for example, “1” and “100”) as a big hit determination value, the big hit is determined with a predetermined big hit probability (eg, 1/100). As a result, the number of types of determination values to be processed is smaller when the random number by the 12-bit random number circuit 503a is used than when the random number by the 16-bit random number circuit 503b is used, and the game control microcomputer 560 is used. The control burden is reduced.

  Further, the CPU 56 executes processing in accordance with the random number maximum value setting module 551a included in the random number circuit setting program 551, and generates random number maximum value setting data for designating a random number maximum value preset by the user as a random number maximum value setting register 535. (Step S152). By doing so, the random number maximum value of random R preset by the user is set in the random number circuit 503. When the 12-bit random number circuit 503a is set as the random number circuit used when the timer interrupt is executed, the CPU 56 sets the random number maximum value designating the random number maximum value (any value from “0” to “4095”). Data is written into the random number maximum value setting register 535 of the 12-bit random number circuit 503a. Further, when the 16-bit random number circuit 503b is set as the random number circuit used when the timer interrupt is executed, the CPU 56 sets the random number maximum value for designating the maximum random number value (any value from “0” to “65535”). Data is written into the random number maximum value setting register 535 of the 16-bit random number circuit 503b.

  In this embodiment, when “0” to “255” are set as the random number maximum value, the random number maximum value is reset to a predetermined value in the random number maximum value resetting process described later. Even when control is performed to write a value greater than “256” as the random number maximum value, values “0” to “255” are set in the random number maximum value setting register 535 due to garbled data or the like. In the case where it is lost, the random number maximum value is reset to a predetermined value in the random number maximum value resetting process described later.

  As described above, since the maximum value of the random number to be generated is set in advance in the random number maximum value setting register 535 in step S152, a random number having a value larger than the range of random numbers used during execution of the timer interrupt process is generated. Can be prevented, and the processing load on the random number circuit 503 and the game control microcomputer 560 can be reduced.

  Further, the CPU 56 checks whether the random number maximum value set in the random number maximum value setting register 535 in step S152 is not less than a predetermined lower limit value. If the random number maximum value is not more than the lower limit value, the random number maximum value setting register The random number maximum value resetting process for resetting the random number maximum value set in 535 is executed (step S153).

  Further, the CPU 56 executes a process according to the initial value change module 551e included in the random number circuit setting program 551, and executes an initial value change process for changing the initial value of the count value updated by the counter 521 of the random number circuit 503 (step). S154).

  Further, the CPU 56 executes processing according to the random number update method selection module 551b included in the random number circuit setting program 551, and writes the random number update method selection data in the random number update method selection register 540 (step S155). By doing so, the random number update method of the random number circuit 503 is set. In this embodiment, the CPU 56 writes the random number update method selection data “10h” in the random number update method selection register 540. That is, in this embodiment, the second random number update method is set as the random number update method of the random number circuit 503.

  Further, the CPU 56 executes processing in accordance with the cycle setting module 551c included in the random number circuit setting program 551, and sets the cycle setting data (the reference clock signal by how many minutes) that specifies the cycle of the random number generating clock signal SI1 preset by the user. The data for setting whether to circulate) is written in the period setting register 537 (step S156). By doing so, the cycle of the random number generating clock signal SI1 preset by the user is set in the random number circuit 503.

  Further, the CPU 56 sets whether or not to update the initial value input to the counter 521 when the count value is updated to a predetermined final value by the counter 521 of the random number circuit 503 (step S157). For example, the game control microcomputer 560 sets in advance a setting value indicating whether or not to update the initial value input to the counter 521 when the count value is updated to a predetermined final value by the counter 521. And stored in a predetermined area of the RAM 55. Whether or not the CPU 56 updates the initial value input to the counter 521 when the counter 521 updates the count value to a predetermined final value according to a predetermined set value stored in a predetermined storage area of the RAM 55. Set up. In this embodiment, when the CPU 56 determines in step S157 that the initial value input to the counter 521 is to be updated, the count value is updated to a predetermined final value (when a notification signal is input from the counter 521). An initial value update flag indicating that the initial value is updated is set.

  Further, the CPU 56 sets whether or not to change the permutation of the count values updated by the counter 521 when the count value is updated to a predetermined final value by the counter 521 of the random number circuit 503 (step S158). For example, the game control microcomputer 560 sets a preset value indicating whether or not to change the permutation of count values output by the counter 521 when the counter 521 updates the count value to a predetermined final value. Is stored in a predetermined area of the RAM 55. Then, the CPU 56 changes the permutation of count values output by the counter 521 when the count value is updated to a predetermined final value by the counter 521 in accordance with a predetermined set value stored in a predetermined storage area of the RAM 55. Set whether or not. In this embodiment, if the CPU 56 determines in step S158 that the permutation of count values output by the counter 521 is to be changed, the CPU 56 changes the permutation of count values when the count value is updated to a predetermined final value. The indicated count value permutation change flag is set. In this embodiment, the case where the count value permutation change flag is set in step S158 according to a predetermined set value will be described. Then, the CPU 56 changes the permutation of the count values output by the counter 521 based on the fact that the count value permutation change flag is set in the count value permutation changing process described later.

  Then, the CPU 56 executes processing according to the random number circuit activation module 551d included in the random number circuit setting program 551, and writes the random number circuit activation data “80h” in the random number circuit activation register 541 (step S159). By doing so, the game control microcomputer 560 activates the random number circuit 503.

  Next, the random number maximum value resetting process (step S153) in the random number circuit setting process will be described. FIG. 31 is a flowchart showing the random number maximum value resetting process. In the random number maximum value resetting process, the CPU 56 reads the random number maximum value set in the random number maximum value setting register 535 (step S153a). When the 12-bit random number circuit 503a is set as the random number circuit used when the timer interrupt process is executed, the CPU 56 reads the random number maximum value set in the random number maximum value setting register 535 of the 12-bit random number circuit 503a. When the 16-bit random number circuit 503b is set as the random number circuit used when the timer interrupt process is executed, the CPU 56 reads the random number maximum value set in the random number maximum value setting register 535 of the 16-bit random number circuit 503b.

  The game control microcomputer 560 determines whether or not the read random number maximum value is equal to or less than a predetermined lower limit value (step S153b). When the 12-bit random number circuit 503a is set, the maximum random number that can be set in the 12-bit random number circuit 503a is from “256” to “4095”. It is determined whether or not the random number maximum value read from is less than or equal to the lower limit value “256”. When the 16-bit random number circuit 503b is set, the maximum random number that can be set in the 16-bit random number circuit 503b is from “256” to “65535”. It is determined whether or not the maximum random number read from the register 535 is equal to or lower than the lower limit “256”.

  When the read random number maximum value is less than or equal to the lower limit value, the game control microcomputer 560 resets the random number maximum value set in the random number maximum value setting register 535 to a predetermined value (step S153c). When the 12-bit random number circuit 503a is set, the CPU 56 determines that the random number maximum value read from the random number maximum value setting register 535 of the 12-bit random number circuit 503a is equal to or less than the lower limit “256”, the CPU 56 determines the random number maximum value setting register 535. The random number maximum value set in is reset to a predetermined value “4095”. When the 16-bit random number circuit 503b is set, if it is determined that the random number maximum value read from the random number maximum value setting register 535 of the 16-bit random number circuit 503b is equal to or less than the lower limit “256”, the CPU 56 sets the random number maximum value. The random number maximum value set in the register 535 is reset to a predetermined value “65535”.

  As described above, when the random number maximum value set in the random number maximum value setting register 535 is less than or equal to the predetermined lower limit value, the random number maximum value is reset to a predetermined value. Therefore, it is possible to prevent an excessively small value from being set as the maximum value of the random number due to a malfunction of the game control microcomputer 560 or an action such as generating a capture signal using a radio signal for the game machine. be able to. Therefore, it is possible to prevent a situation in which a random number having an excessively small value range from the minimum value to the maximum value is generated.

  Next, the initial value changing process (step S154) in the random number circuit setting process will be described. FIG. 32 is a flowchart showing the initial value changing process. In the initial value changing process, the CPU 56 first reads the initial value changing method setting data stored in the area 1F97h in the user program execution data area, and specifies the initial value changing method selected by the user. In this case, the CPU 56 determines whether or not the value of the read initial value changing method setting data is “01h” (step S154a), thereby specifying the initial value changing method selected by the user.

  When the value of the initial value change method setting data is “01h”, the CPU 56 sets the initial value input to the counter 521 of the random number circuit 503 to a value set based on the ID number unique to the game control microcomputer 560. Change (step S154b). For example, the game control microcomputer 560 associates, in a predetermined storage area of the RAM 55, the ID number of the game control microcomputer 560 with a calculation value obtained by performing a predetermined calculation based on the ID number. I remember it. In step S154b, the CPU 56 changes the initial value of the count value to the calculated value based on the ID number stored in advance. Further, for example, in step S154b, the CPU 56 calculates the ID number of the game control microcomputer 560 and a predetermined value (for example, the ID number (for example, “100”) to a predetermined value (for example, “100”). The initial value of the count value is set to the calculated value (for example, “200”). When the initial value input to the counter 521 is changed, the CPU 56 sets an initial value change flag indicating that the initial value of the count value has been changed (step S154c).

  When the game control microcomputer 560 changes the initial value input to the counter 521 in step S154b, the game control microcomputer 560 checks the value of the random number maximum value setting register 535 of the comparator 522 of the random number circuit 503, and based on the ID number. It is determined whether or not the set value is greater than or equal to the random number maximum value. When it is determined that the value set based on the ID number is equal to or greater than the maximum random number, the game control microcomputer 560 does not change the initial value input to the counter 521 (for example, the initial value is “0”). Do not change). By doing so, it is possible to prevent a situation where the initial value of the count value is set to a value equal to or greater than the maximum random number.

  If the value of the initial value change method setting data is not “01h” in step S154a (that is, the value of the initial value change method setting data stored in the area 1F97h of the user program execution data area is “00h”). In the case), the CPU 56 does not change the initial value of the count value, ends the initial value changing process as it is, and proceeds to step S155.

  By executing the random number circuit setting process, various signals are input to the random number circuit 503 when the timer interrupt process including the game control process is performed, and various signals are generated in the random number circuit 503. FIG. 33 is a timing chart showing the timing at which each signal is input to the random number circuit 503 and the timing at which each signal is generated in the random number circuit 503.

  As shown in FIG. 33, the clock circuit 501 increases the signal level of the output terminal from a low level to a high level at predetermined intervals (timing T11, T21,... Shown in FIG. 33). A reference clock signal CLK (see FIG. 33A) is input to 503.

  The clock signal output circuit 524 divides the reference clock signal CLK supplied from the clock circuit 501 to generate a random number generation clock signal SI1 (see FIG. 33B). For example, the clock signal output circuit 524 raises the signal level of the output terminal from the low level to the high level at timings T11, T12,..., And changes the signal level from the high level to the low level at timings T21, T22,. To output a random number generating clock signal SI1.

  In the example shown in FIG. 33, the clock signal output circuit 524 generates the random number generating clock signal SI1 by dividing the reference clock signal CLK by two for easy understanding. However, in the actual random number circuit, the period that can be set in the period setting register 537 is from “system clock signal period × 128 × 7” to “system clock signal period × 128 × 256”. Therefore, in an actual random number circuit, the clock signal output circuit 524 is set in the cycle setting register 537 in a range from “system clock signal cycle × 128 × 7” to “system clock signal cycle × 128 × 256”. The reference clock signal CLK is divided by a division ratio corresponding to the cycle setting data “07h” to “FFh” to generate a random number generating clock signal SI1. The random number generating clock signal SI 1 generated by the clock signal output circuit 524 is output to the selector 528 and the inverting circuit 532.

  In this embodiment, since the second random number update method is set in the random number circuit setting process, the second random number update method selection signal is input from the random number update method selection signal output circuit 527 to the selector 528. When the second random number update method selection signal output circuit 527 receives the second random number update method selection signal output circuit 527, the selector 528 selects the random number generation clock signal SI1 input from the clock signal output circuit 524 and outputs it to the counter 521. . The counter 521 updates the count value C and outputs it to the count value permutation change circuit 523 every time the rising edge of the random number generation clock signal SI1 supplied from the selector 528 is input.

  The inversion circuit 532 generates the inverted clock signal SI2 (see FIG. 33C) by inverting the signal level of the random number generation clock signal SI1 input from the clock signal output circuit 524. For example, the inverting circuit 532 lowers the signal level of the output terminal from the high level to the low level at timings T11, T12,..., And the signal level from the low level to the high level at timings T21, T22,. As a result, the inverted clock signal SI2 is output. Further, the inverted clock signal SI <b> 2 generated by the inverting circuit 532 is output to the latch signal generating circuit 533.

  When a predetermined time (for example, 3 milliseconds) elapses after the winning detection signal SS (see FIG. 33D) is input to the latch circuit generation circuit 533, the random number value read signal output circuit 526 receives a disturbance. A numerical reading signal is input. For example, when the signal level of the output terminal of the random number read signal output circuit 526 rises from a low level to a high level, the random value read signal is input to the latch signal generation circuit 533. The latch signal generation circuit 533 inverts the random value read signal input from the random value read signal output circuit 526 in response to the input of the second random number update method selection signal from the random number update method selection signal output circuit 527. A latch signal SL (see FIG. 33E) is output in synchronization with the rising edge of the inverted clock signal SI2 supplied from 532.

  As described above, the random number circuit 503 updates the count value C at the timings T11, T12, T13... And outputs the latch signal SL at the timing T22 different from the timings T11, T12, T13. The random number value is stored in 531.

  Next, the game control process will be described. FIG. 34 is a flowchart showing the timer interrupt process. When a timer interrupt occurs during execution of the main process, specifically, during a period when the interrupt is permitted during the execution of the loop process of steps S17 to S19, the game control microcomputer 560 causes the timer The game control process is executed in the timer interrupt process that is activated in response to the occurrence of the game. In the timer interrupt process, the game control microcomputer 560 first executes a power-off process (power-off detection process) for detecting whether or not a power-off signal is output (whether or not it is turned on) ( Step S20). Subsequently, detection signals of switches such as the gate switch 32a, the start port switch 14a, the count switch 23, and the winning port switches 29a, 30a, 33a, and 39a are input via the switch circuit 58, and their state is determined (switch) Process: Step S21). Specifically, if the state of the input port for inputting the detection signal of each switch is ON, the value of the switch timer provided corresponding to each switch is incremented by one.

  Next, the game control microcomputer 560 confirms whether or not the initial value is updated when the count value is updated to a predetermined final value in the random number circuit setting process (see step S157). A process of updating the initial value input to the counter 521 of the random number circuit 503 is performed (initial value update process: step S22). Further, the game control microcomputer 560 performs a process of updating the count value of the counter for generating the display random number (display random number update process: step S23).

  When the initial value update process and the display random number update process are performed, the game control microcomputer 560 causes the count value permutation change circuit 523 to change the count value permutation output by the counter 521 of the random number circuit 503. Is performed (step S24). In this embodiment, whether or not to execute the count value permutation change process is determined depending on whether or not the count value permutation change flag is set in step S158 of the random number circuit setting process. Then, the game control microcomputer 560 executes the count value permutation change process based on the fact that the count value permutation change flag is set.

  Furthermore, the game control microcomputer 560 performs a special symbol process (step S25). In the special symbol process control, corresponding processing is selected and executed according to a special symbol process flag for controlling the pachinko gaming machine 1 in a predetermined order according to the gaming state. The value of the special symbol process flag is updated during each process according to the gaming state. Further, normal symbol process processing is performed (step S26). In the normal symbol process, the corresponding process is selected and executed according to the normal symbol process flag for controlling the display state of the normal symbol display 10 in a predetermined order. The value of the normal symbol process flag is updated during each process according to the gaming state.

  Next, the game control microcomputer 560 performs a process of setting an effect control command related to the decorative symbol synchronized with the variation of the special symbol in a predetermined area of the RAM 55 and sending the effect control command (decorative symbol command control process: step) S27). Note that the fact that the variation of the decorative symbol is synchronized with the variation of the special symbol means that the variation time (variable display period) is the same.

  Further, the game control microcomputer 560 performs information output processing for outputting data such as jackpot information, start information, probability variation information supplied to the hall management computer, for example (step S28).

  Further, the game control microcomputer 560 executes prize ball processing for setting the number of prize balls based on detection signals from the prize opening switches 29a, 30a, 33a, 39a, etc. (step S29). Specifically, a payout command signal such as a prize ball number signal indicating the number of prize balls is output to the payout control board 37 in response to winning detection based on the fact that the prize opening switches 29a, 30a, 33a, 39a, etc. are turned on. . The payout control microcomputer 370 mounted on the payout control board 37 drives the ball payout device 97 in response to receiving a prize ball number signal indicating the number of prize balls.

  Then, the game control microcomputer 560 executes a storage process for checking an increase or decrease in the number of reserved storage (step S30). In addition, a test terminal process, which is a process for outputting a test signal for enabling the control state of the gaming machine to be confirmed outside the gaming machine, is executed (step S31). In this embodiment, a RAM area (output port buffer) corresponding to the output state of the output port is provided. However, the game control microcomputer 560 is related to the solenoid in the RAM area of the output port 2. Is output to the output port (step S32: solenoid output processing). Thereafter, the game control microcomputer 560 sets the interrupt permitted state (step S33), and ends the process.

  With the above control, in this embodiment, the game control process is started periodically (for example, every 2 ms). In this embodiment, the game control process is executed by the timer interrupt process. However, in the timer interrupt process, for example, only a flag indicating that an interrupt has occurred is set, and the game control process has a flag. It may be executed in the main process based on the setting. Further, the processing of steps S21 to S32 (excluding steps S28 and S31) corresponds to a game control process for controlling the progress of the game.

  In addition, the game control microcomputer 560 executes a process of counting the number of times the timer interrupt process has been executed. In this embodiment, each time the game control microcomputer 560 executes the timer interrupt process, the game control microcomputer 560 counts up an interrupt number counter indicating the number of times the timer interrupt process has been executed. For example, when the game control microcomputer 560 completes the solenoid output process in step S32, the game control microcomputer 560 adds 1 to the value of the interrupt counter indicating the number of times the timer interrupt process has been executed.

  Next, the initial value update process (step S22) in the timer interrupt process will be described. FIG. 35 is a flowchart showing the initial value update process. In the initial value update process, the game control microcomputer 560 checks the state of the notification signal indicating that the count value C output from the counter 521 of the random number circuit 503 has been updated to the final value (step S220). When it is detected that the notification signal is on, the game control microcomputer 560 checks whether or not the initial value update flag is set (step S221). That is, the game control microcomputer 560 confirms whether or not the setting for updating the initial value is made when the count value is updated to a predetermined final value in the random number circuit setting process (see step S157). .

  When the initial value update flag is set, the game control microcomputer 560 determines to update the initial value input to the counter 521 when the counter 521 of the random number circuit 503 updates the count value to a predetermined final value. To do. If the initial value update flag is set, the game control microcomputer 560 checks whether the initial value change flag is set (step S222). That is, the game control microcomputer 560 determines whether or not the initial value of the count value is currently changed (that is, whether or not it is changed to a value based on the ID number of the game control microcomputer 560).

  When the initial value change flag is set (that is, the initial value is currently changed based on the value based on the ID number of the game control microcomputer 560), the game control microcomputer 560 inputs the initial value to the counter 521. The value is returned to the original value (for example, “1”) from the value based on the ID number of the game control microcomputer 560 (step S223). Then, the game control microcomputer 560 resets the initial value change flag (step S224), and ends the initial value update process.

  If the initial value change flag is not set (that is, the initial value is not currently changed), the game control microcomputer 560 uses the initial value input to the counter 521 as the ID number of the game control microcomputer 560. The value is changed to the original value (step S225). In this case, for example, when the ID number of the game control microcomputer 560 is “100”, the initial value input to the counter 521 is calculated by adding a predetermined value “100” to the ID number “100”. Change to the value “200”. Further, for example, the initial value input to the counter 521 is changed to the calculated value “50” obtained by subtracting the predetermined value “50” from the ID number “100”. Then, the game control microcomputer 560 sets an initial value change flag (step S226), and ends the initial value update process.

  When both the 12-bit random number circuit 503a and the 16-bit random number circuit 503b are set, in step S225, the game control microcomputer 560 uses the random number read from one random number circuit (for example, the 12-bit random number circuit 503a). An initial value input to the counter 521 may be obtained by adding the ID number as a predetermined value. Then, the game control microcomputer 560 may use the random number read from the other one (for example, the 16-bit random number circuit 503b) as the random number for determining the big hit.

  When the game control microcomputer 560 updates the initial value input to the counter 521 in step S225, the game control microcomputer 560 checks the value of the random number maximum value setting register 535 of the comparator 522 of the random number circuit 503, and based on the ID number. It is determined whether or not the set value is greater than or equal to the random number maximum value. When it is determined that the value set based on the ID number is equal to or greater than the maximum random number, the game control microcomputer 560 does not update the initial value input to the counter 521 with the predetermined value (for example, the predetermined value “ 0 ”is not updated). By doing so, it is possible to prevent a situation where the initial value of the count value is set to a value equal to or greater than the maximum random number.

  If it is determined in step S220 that the notification signal is in the off state, and if it is determined in step S221 that the initial value update flag is not set, the game control microcomputer 560 inputs the initial value to the counter 521. Without updating the initial value update process, the process proceeds to step S23.

  Next, the count value permutation change process (step S24) in the timer interrupt process will be described. FIG. 36 is a flowchart showing the count value permutation changing process. The game control microcomputer 560 executes the count value permutation change process by executing the process according to the count value permutation change program 554. In the count value permutation changing process, the game control microcomputer 560 checks the state of the notification signal indicating that the count value C output from the counter 521 of the random number circuit 503 has been updated to the final value (step S241). When it is detected that the notification signal is turned on, the game control microcomputer 560 checks whether or not the count value permutation change flag is set (step S242). That is, whether or not the game control microcomputer 560 has been set to change the permutation of the count values updated by the counter 521 when the count values are updated to a predetermined final value in the random number circuit setting process ( Confirm step S158).

  When the count value permutation change flag is set, the game control microcomputer 560 displays the permutation of the count values that the counter 521 updates when the counter 521 of the random number circuit 503 updates the count values to a predetermined final value. Judge to change. Then, the game control microcomputer 560 writes the count value permutation change data “01h” in the count value permutation change register 536 (step S243). That is, the game control microcomputer 560 causes the count value permutation change circuit 523 to change the permutation of the count values C input to the random value storage circuit 531 by writing the count value permutation change data “01h”.

  As described above, in the count value permutation changing process, when the random number is updated to a predetermined final value, the permutation of the count value updated by the counter 521 is changed, so that the randomness generated by the random number circuit 503 is more random. Can be improved.

  Next, the special symbol process (step S25) in the main process will be described. FIG. 37 is a flowchart showing an example of a special symbol process processing program executed by the game control microcomputer 560. When performing the special symbol process, the game control microcomputer 560 performs a variable shortening timer subtraction process (step S310), and detects that a game ball has won the start winning opening 14 provided in the game board 6. If the start opening switch 14a for turning on is turned on, that is, if a start winning that causes the game ball to win the start winning opening 14 has occurred (step S311), after performing the start opening switch passing process (step S312), Depending on the internal state, any one of steps S300 to S308 is performed. The variation shortening timer is a timer for setting the variation time when the variation time of the special symbol is shortened.

  Special symbol normal processing (step S300): A state where variable symbol special display can be started (for example, the symbol variation has not been made in the special symbol display 8, and the previous symbol variation in the special symbol display 8 has ended) Wait for a predetermined period of time to elapse, and not a big hit game). When the special symbol variable display can be started, the start winning memory number for the special symbol is confirmed. If the start winning memorized number is not 0, it is determined based on the random R generated by the random number circuit 503 whether or not the result of variable symbol special display is a big hit. Then, the internal state (special symbol process flag) is updated so as to shift to step S301.

  Special symbol stop symbol setting process (step S301): A stop symbol after variable display of the special symbol is determined. Then, the internal state (special symbol process flag) is updated so as to shift to step S302.

  Variation time setting process (step S302): A variation pattern is determined, and variation time in the variation pattern (variable display time: time from when variable display is started until display result is derived and displayed (stop display)) is a special symbol. It is determined to be a variable display variable time. In addition, a variation time timer that measures the variation time of the determined special symbol is started. Then, the internal state (special symbol process flag) is updated so as to shift to step S303.

  Special symbol variation process (step S303): When a predetermined time (the time indicated by the variation time timer in step S302) elapses, the internal state (special symbol process flag) is updated to shift to step S304.

  Special symbol stop process (step S304): A decorative symbol stop command for instructing stop of the decorative symbol is transmitted to the effect control board 80. Moreover, the special symbol in the special symbol display 8 is stopped. If the stop symbol of the special symbol is a big hit symbol, the internal state (special symbol process flag) is updated to shift to step S305. If not, the internal state is updated to shift to step S300. Note that a configuration in which a decorative symbol stop command is not transmitted may be employed. In this case, the effect control board 80 sets the change time in the change time timer based on the change pattern command from the main board 31 and updates the change time timer to uniquely change the change time of the decorative pattern. What is necessary is just to perform the process which stops the decorative design when it monitors and it determines with the fluctuation | variation time having passed.

  Preliminary winning opening opening process (step S305): Control for opening the large winning opening is started. Specifically, a counter (for example, a counter that counts the number of game balls that have entered the grand prize opening) and a flag (a flag used when detecting winning in the prize opening) are initialized, and the solenoid 21 is driven. Open the big prize opening. Also, the process timer sets the execution time of the big prize opening opening process and sets the big hit flag. Then, the internal state (special symbol process flag) is updated so as to shift to step S306.

  Processing for opening a special prize opening (step S306): control for sending a presentation control command for round display of the special prize opening to the production control board 80 and closing conditions for the special prize opening (for example, a predetermined number (for example, 10 for the special prize opening) ) To confirm that the game ball has won a prize). When the closing condition for the special prize opening is satisfied, the internal state is updated to shift to step S307.

  Specific area valid time process (step S307): The presence / absence of passing through the V winning switch 22 is monitored, and a process of confirming that the big hit gaming state continuation condition is satisfied is performed. If the condition for continuing the big hit gaming state is satisfied and there are still remaining rounds, the internal state is updated to shift to step S305. In addition, when the big hit gaming state continuation condition is not satisfied within a predetermined effective time, or when all rounds are finished, the internal state is updated to shift to step S308.

  Big hit end processing (step S308): Control for causing the effect control means to perform display control for notifying the player that the big hit gaming state has ended. Then, the internal state is updated so as to shift to step S300.

  FIG. 38 is a flowchart showing the start port switch passage process (step S312). In the start-port switch passing process, the game control microcomputer 560 has reached the maximum value of 4 for the start winning memory number (or the starting winning memory number stored in the special figure holding memory 570) indicated by the start winning counter. It is confirmed whether or not (step S321). If the start winning memory number has not reached 4, the game control microcomputer 560 determines whether or not the number of executions of the timer interrupt process indicated by the interrupt execution number counter has reached a predetermined number (for example, 3 times). Is confirmed (step S322). When it is detected that the game ball has won the start winning opening 14, the game control microcomputer 560 resets the interrupt execution counter. Then, the game control microcomputer 560 checks whether or not the interrupt execution number counter has reached a predetermined number after the game ball has won the start winning opening 14.

  The value set in advance as the predetermined number of times in step S322 is determined as follows. As described above, the timer circuit 534 of the random number circuit 503 measures the time that the winning detection signal SS is continuously input from the start port switch 14a, and detects that the measurement time has reached a predetermined period, Write numerical value capture data “01h”. In this embodiment, a predetermined period (for example, 3 ms) measured by the timer circuit 534 is a period in which a predetermined number of timer interrupt processes are executed (for example, when the timer interrupt process for every 2 ms is executed three times). The predetermined number (for example, 3 times) used in step S322 is set so as to be shorter than 6 ms). By setting in this way, it is possible to prevent the random number from being read again after the random number is read and before the random number value stored in the random value storage circuit 531 is updated. It is possible to prevent a random number having the same value as the random number read from the circuit 531 from being read again.

  When the number of executions of the timer interrupt process has reached a predetermined number, the CPU 56 can output the output control signal SC to the random number storage circuit 531 of the specified random number circuit 503 and read the random number storage circuit 531 (enable). The state is controlled (step S323).

  The CPU 56 reads the random R value stored as the random number value from the random number value storage circuit 531 of the random number circuit 503 (step S324). Further, the CPU 56 stores the read random R value in, for example, a predetermined buffer area provided in the RAM 55 (step S325). When the CPU 56 stores the value of the random R in the buffer area, the CPU 56 stops outputting the output control signal SC to the random value storage circuit 531 and controls the random value storage circuit 531 to be unreadable (disabled) (step). S326). Further, the CPU 56 resets the interrupt execution number counter (step S327). Then, the CPU 56 sets the value of the random R stored in the predetermined buffer area to the head of the empty entry in the special figure reservation memory 570 (step S328), and adds 1 to the count number of the start winning counter, thereby storing the start winning memory. The number is incremented by 1 (step S329).

  If the start prize is stored in step S321 but the maximum value of 4 has been reached, and if the number of executions of the timer interrupt process has not reached the predetermined number in step S322, the start port switch passing process is terminated.

  As described above, the timer interrupt process has been executed a predetermined number of times in reading the random R from the random value storage circuit 531 in the starting port switch passing process (that is, continued while the timer interrupt process is executed a predetermined number of times). The random number is read from the random value storage circuit 531 on the condition that the winning detection signal SS is input). Therefore, it is possible to prevent the random number from being read again after the random number is read and before the value of the random number stored in the random value storage circuit 531 is updated. Further, it is possible to prevent a random number having the same value as the random number read from the previous random number value storage circuit 531 from being read again.

  Next, the special symbol normal process (step S300) in the special symbol process will be described. FIG. 39 is a flowchart showing a special symbol normal process executed when the big hit game is finished. In the special symbol normal processing, the game control microcomputer 560 is in a state where the variation of the special symbol can be started (for example, when the value of the special symbol process flag is a value indicating step S300) (step S380). ), The value of random R stored in correspondence with the hold number “1” is read from the special figure hold memory 570 (step S381). In this case, the game control microcomputer 560 decrements the number of reserved memories by decrementing the count of the start winning counter by 1, and the second to fourth entries (holding number “2”) in the special figure holding memory 570. To “4”), the value of random R is shifted upward by one entry (step S382).

  Further, the game control microcomputer 560 checks whether or not the probability variation flag is set (step S383). That is, the game control microcomputer 560 checks whether or not the game state is controlled to the certain change state. When the probability change flag is not set, the game control microcomputer 560 determines that the game state is a normal state other than the probability change state, and determines whether or not the display result of the special symbol display device 8 is a jackpot symbol. As a table used to do this, a normal jackpot determination table 571a (see FIG. 27A) is set (step S384). When the probability change flag is set, the game control microcomputer 560 determines that the game state is a probability change state and determines whether or not the display result of the special symbol display device 8 is a jackpot symbol. As a table used for the above, a probability change big hit determination table 571b (see FIG. 27B) is set (step S385).

  The game control microcomputer 560 determines whether or not the display result of the special symbol display device 8 is a jackpot symbol based on the random R value stored in a predetermined buffer area in the start port switch passing process (step S1). S386). In this case, the game control microcomputer 560 determines whether or not to make a big hit using the normal time big hit determination table 571a set in step S384 or the probability change big hit determination table 571b set in step S385.

  If it is determined that the display result of the special symbol display device 8 is a jackpot symbol, the game control microcomputer 560 turns on a jackpot flag indicating that it is a jackpot state (step S387). If it is determined that the display result of the special symbol display device 8 is not a jackpot symbol, the game control microcomputer 560 turns off the jackpot flag (step S388). Then, the game control microcomputer 560 updates the value of the special symbol process flag to a value corresponding to the special symbol stop symbol setting process (step S389).

  As described above, in this embodiment, the random number circuit 503 is initially set (random number circuit setting process) from the start of power-on to the gaming machine until the timer interrupt is set, and the random number circuit In the setting process, a value based on the ID number unique to the game control microcomputer 560 is set as the initial value of the random number. Therefore, the randomness of the random number generated by the random number circuit 503 can be improved. In addition, since the randomness of random numbers can be improved, the timing of random number generation can be made difficult to be recognized by a player or a game store, and by generating a capture signal using a radio signal for a gaming machine It is possible to prevent the condition for shifting to a specific gaming state such as a big hit state from being illegally established.

  In this embodiment, the inverting circuit 532 of the random number circuit 503 generates the inverted clock signal SI2 whose polarity is inverted, and outputs a latch signal for instructing storage of the random number in synchronization with the inverted clock signal SI2. . Therefore, the timing for updating the random number and the timing for storing the random number in the random value storage circuit 531 can be shifted, and the generated random number can be stored stably and reliably.

Embodiment 2. FIG.
In the first embodiment, the clock signal input to the latch signal generation circuit 533 is inverted, and the timing for updating the random number and the timing for storing the random number in the random value storage circuit 531 are shifted. The clock signal input to the generation circuit 533 may be delayed. Hereinafter, a second embodiment in which a clock signal input to the latch signal generation circuit 533 is delayed will be described.

  In the present embodiment, detailed description of the parts having the same configuration and processing as those of the first embodiment will be omitted, and parts different from the first embodiment will be mainly described.

  FIG. 40 is a block diagram illustrating another configuration example of the random number circuit 503. In this embodiment, the basic configurations of the 12-bit random number circuit 503a and the 16-bit random number circuit 503b are the same. As shown in FIG. 40, this embodiment differs from the first embodiment in that the random number circuit 503 includes a delay circuit 532A in place of the inverting circuit 532 shown in FIG.

  The delay circuit 532A delays the random number generation clock signal SI1 input from the clock signal output circuit 524, thereby generating a delayed clock signal SI4 obtained by delaying the clock signal. Further, the delay circuit 532A outputs the generated delayed clock signal SI4 to the latch signal generation circuit 533. Therefore, in this embodiment, the latch signal generation circuit 533 outputs a latch signal to the random value storage circuit 531 in synchronization with the delayed clock signal SI4 obtained by delaying the random number generation clock signal SI1.

  The basic functions of the constituent elements of the random number circuit 503 other than the delay circuit 532A are the same as those functions described in the first embodiment.

  As described above, in this embodiment, the delay circuit 532A of the random number circuit 503 generates the delayed clock signal SI4 and outputs a latch signal for instructing storage of the random number in synchronization with the delayed clock signal SI4. . Therefore, the timing for updating the random number and the timing for storing the random number in the random value storage circuit 531 can be shifted, and the generated random number can be stored stably and reliably.

  Next, the overall configuration of a slot machine (slot machine), which is another example of the gaming machine in each of the embodiments described above, will be described. FIG. 41 is a front view of the slot machine as seen from the front.

  As shown in FIG. 41, in the slot machine 600, a game panel 601 is detachably attached near the center. Further, a variable display device 602 for variably displaying a plurality of types of symbols is provided near the center of the front surface of the game panel 601. In this embodiment, the variable display device 602 has three symbol display areas of “left”, “middle”, and “right”, and the symbol display reels 602a, 602b, and 602c correspond to the symbol display areas, respectively. Is provided.

  Below the game panel 601, an operation table 620 is provided in which various input switches and the like for the player to perform various operations are arranged. On the back side of the operation table 620, a BET switch 621 for betting (paying) coins one by one, and a MAXBET switch 622 for betting coins by the maximum number (three in this example) that can be placed in one game. A settlement switch 623 and a coin insertion slot 624 are provided. Coins inserted into the coin insertion slot 624 are detected by an inserted coin sensor (not shown).

  On the front side of the operation table 620, a start switch 625, a left reel stop switch 626a, a middle reel stop switch 626b, a right reel stop switch 626c, and a coin jam elimination switch 627 are provided. Lamps 628a and 628b are provided on the right and left sides of the operation table 620, respectively. Below the operation table 620, a speaker 630 for outputting sound effects and the like is provided.

  On the upper part of the game panel 601, an image display device (LCD: liquid crystal display device) 640 for notifying a player of a game method, a game state, and the like is provided. For example, when a winning occurs, an image in which a character performs a predetermined action is displayed on the image display device 640 to notify the player that a winning flag described later is set. Two speakers 641L and 641R that emit sound effects are provided on the left and right of the image display device 640.

  The winning combinations generated in the slot machine 600 include a small winning combination, a replay winning, a big bonus winning, and a regular bonus winning. In the slot machine 600, random numbers are extracted at the timing when the start switch 625 is operated, and it is determined whether or not the winning of any winning combination is allowed. The fact that winnings are allowed is said to be “winning internally”. When an internal winning is made, a winning flag indicating that is set in the slot machine 600. In the game with the winning flag set, the reels 602a to 602c are controlled so that the winning combination corresponding to the winning flag can be drawn. On the other hand, in a game in which the winning flag is not set, the reels 602a to 602c are controlled so that no winning is generated.

  Note that the game control microcomputer that controls the progress of the game of the slot machine 600 incorporates a random number circuit (12-bit random number circuit and 16-bit random number circuit) that generates random numbers. Further, the game control microcomputer extracts the random number (random R) generated by the random number circuit at the timing when the start switch 625 is operated. For example, when the start switch 625 is pressed, the game control microcomputer 560 inputs the detection signal SS from the start switch 625. When the timer circuit 534 of the random number circuit detects that the detection signal SS has been input continuously for a predetermined time, the random number value fetch data “01h” is written to the random value fetch register 539 and the latch signal generation circuit 533 is written. Outputs the latch signal SL to the random value storage circuit 531. When the latch signal SL is input, the random value storage circuit 531 reads and stores the count value updated by the counter 521. In addition, when the game control microcomputer 560 detects that the detection signal SS has been input continuously for a predetermined number of times (for example, three times), it outputs the output control signal SC to the random value storage circuit of the random number circuit. Then, a random value (random R) is extracted from the random number circuit. Then, the game control microcomputer determines whether or not the winning is allowed based on the extracted random R.

Next, an outline of the game provided by the slot machine will be described.
For example, when a multiplier is set by inserting a coin from the coin insertion slot 624 and pressing the BET switch 621 or the MAXBET switch 622, the operation of the start switch 625 becomes effective. When the player operates the start switch 625, the symbol display reels 602a to 602c provided in the variable display device 602 start rotating. In addition, when a regular bonus prize or a big bonus prize is won internally at the timing when the start switch 625 is operated, for example, a screen on which a predetermined character performs a predetermined action is displayed on the image display device 640. Thus, the player or the like is notified that the internal winning is made.

  When a predetermined time elapses after the symbol display reels 602a to 602c start rotating, the operations of the reel stop switches 626a to 626c become effective. In this state, if the player presses one of the reel stop switches 626a to 626c, the rotation of the reel corresponding to the operated stop switch is stopped. When the symbol display reels 602a to 602c are left for a predetermined period or longer without being stopped, the symbol display reels 602a to 602c are automatically stopped.

  When all the symbol display reels 602a to 602c are stopped, the symbol display reels 602a to 602c displayed on the variable display device 602 are determined according to the number of symbols in the upper, middle and lower three symbols. Whether or not a prize is won is determined by a combination of symbols positioned on a valid winning line.
