Description

The present invention relates to a gaming machine utilizing the random number value is random number generating means to generate the game control.

Conventionally, in a pachinko gaming machine as a gaming machine using a gaming ball, a winning opening called a starting winning opening is provided in a gaming area on a gaming board, and random numbers are acquired based on winning of a hitting ball on the starting winning opening. There is widespread use of gaming machines in which it is determined to be won, and a predetermined benefit (for example, a so-called big hit game) is provided to a player based on the result of the win.
And, this kind of gaming machine which utilizes random numbers for game control is provided with a plurality of random number counters which perform counting operation in a predetermined cycle as means for generating random numbers, and these random number counters are counting at any timing. Some take values and use their counter values as random numbers.

By the way, in a gaming machine provided with a random number counter as described above, a gaming controller (CPU) acquires a random number at a timing when the value of the random number counter becomes a big hit random number by using an illicit device called a sensation sensor. There are known frauds related to random number acquisition, such as aiming at shooting, and various countermeasures against such frauds are considered.
For example, as in Patent Document 1, the supply of power is started by suppressing the firing of gaming balls until the initial random number initial value (the value at the start of counting in the random number counter) is updated after power is supplied. Even if an attempt is made to operate the launching means by predicting the timing at which the value of the random number counter becomes the big hit judgment value on the basis of the above, by not firing the gaming ball, the invention intentionally prevents the firing aimed at the big hit timing Proposed.

The pair of opening and closing members 37b of the normal fluctuation winning device 37 always maintain a closed state (a disadvantage state for the player) at an interval of about the diameter of the gaming ball. However, since the start winning hole 36 is provided above the normal fluctuation winning device 37, the gaming ball can not win in the closed state.
Then, when the result of the common drawing fluctuation display game becomes a predetermined stop display mode, the common electric power solenoid 37c (see FIG. 4) as a drive device opens in a reverse "ha" shape and receives a normal fluctuation prize The game ball can easily change into the open state (a state advantageous to the player) into which the game ball can flow.
Furthermore, a special variation winning device (big winning opening) 38 which can be converted into a non-accepting state and an easy-to-accepting state according to the result of the special figure fluctuation display game is disposed below the normal symbol start gate 34 There is.

The special variation winning device 38 has an attacker-type opening / closing door which can be opened by turning in the direction in which the upper end side falls to the front side, and as a result of the special figure variation display game as an auxiliary game It changes from the closed state of the winning opening (closed state disadvantageous to the player) to the opened state (advantage to the player).
That is, the special variation winning device 38 has, for example, a special winning opening that is opened and closed by an open / close door driven by a special winning opening solenoid 38b (see FIG. 4) as a drive device. By changing the closed state from the closed state to the open state, the flow of the game ball into the big winning opening is facilitated, and the player is given a predetermined game value (prize ball).

In the inside (winning area) of the special winning opening, a count switch 38a (see FIG. 4) is disposed as a detecting means for detecting the gaming ball having entered the special winning opening.
Furthermore, below the special variation winning device 38, an out port 39 is provided for collecting gaming balls that did not win a prize.
In addition, to the outside of the game area 32 (for example, the lower right part of the game board 30), a first special view change display game or a second special view change display game and a common view start gate 34 making a special view change display game A batch display device 50 is provided which executes a common drawing variation display game triggered by a winning at one place.

  The batch display device 50 is a first special view fluctuation display unit (special view 1 display) 51 for the first special view fluctuation display game configured of a seven-segment type display etc. and a second special view fluctuation display game A second special view change display unit (special view 2 display unit) 52, a change display unit for a common view change display game composed of an LED lamp, and a storage display unit for informing the start memory number of each change display game And an LED display unit 53. In addition, the first game state display unit (the first game state indicator) lights up when a big hit occurs to notify the occurrence of a big hit (first game state indicator) in the LED display unit 53 of the collective display device 50; A second gaming status display section (second gaming status indicator) for reporting status occurrence, and an error display section (third gaming for displaying an error that the probability state of big hit is high probability status when the gaming machine 10 is powered on) A status indicator, a round display unit for displaying the number of rounds at the time of a big hit (number of times of opening and closing of the special variation winning device 38) is provided.

The special view variation display game on the special view 1 display 51 and the special view 2 display 52 is, for example, the middle of the variation display game, ie, while the decorative special view variation display game is being performed on the display device 41. The segment is driven to blink to indicate that it is changing. Then, when the game result is “off”, for example, the central segment is turned on as a result mode of the off, and when the game result is “hit”, the hit result mode (special result mode) is not The game results are displayed with the result modes other than the result mode (for example, the numbers "3" and "7") lit.
As described above, since the special view 1 display 51 and the special view 2 display 52 for executing the special view change display game are provided separately from the display device 41, the change display game of the gaming machine is performed on the display device 41. Even if the effect linked to the effect of the other gaming machine is performed instead of the effect related to, the original variable display game of the gaming machine can be properly executed.

The indicator of the LED display unit 53 blinks the lamp during fluctuation to indicate that fluctuation is occurring. Then, when the result of the game is "off", for example, the lamp is turned off, and when the result of the game is "hit", the lamp is turned on to display the game result.
The special view 1 suspension display displays the number of undivided balls (the number of startup memories = the number of suspension) out of the number of winning balls to the start winning opening 36 serving as the variation start condition of the special view 1 display 51. Specifically, when the number of reservations is “0”, all four lamps are turned off, and when the number of reservations is “1”, only the lamp 1 is turned on. Also, when the number of reservations is "2", lamps 1 and 2 are turned on, when the number of reservations is "3", lamps 1 2 and 3 are turned on, and when the number of reservations is "4", 4 Turn on all four lamps 1 to 4.

The special view 2 hold indicator of the LED display unit 53 is the special view number (= number of reservations) of the starting memory number of the second start winning opening (normal change winning device 37) which becomes the change start condition of the special view 2 indicator 52. 1 Display in the same way as the hold indicator.
The general drawing hold display indicates the number of starting memories (= the number of holdings) of the common drawing start gate 34 serving as the fluctuation start condition of the common drawing display. For example, when the number of reservations is "0", the lamps 1 and 2 are turned off, and when the number of reservations is "1", only the lamp 1 is turned on. Also, when the number of reservations is "2", lamps 1 and 2 are turned on, when the number of reservations is "3", lamp 1 blinks and lamp 2 is turned on, and when the number of reservations is "4" Make lamps 1 and 2 blink.

The first gaming state indicator turns off the lamp in the normal gaming state, for example, and turns on the lamp if a big hit has occurred. The second gaming state indicator turns off the lamp in the normal gaming state, for example, and turns on the lamp in the case of a time saving state. The third gaming state indicator turns off the lamp if, for example, the probability state of big hit is the low probability state when the power of the gaming machine 10 is turned on, and the probability state of the big hit is high probability In the case, turn on the lamp.
The round display unit, for example, turns off the lamp in the normal gaming state, and turns on the lamp (2 rounds or 15 rounds) corresponding to the number of rounds of the big hit when a big hit occurs. The round display unit may be configured by a 7-segment display.

  In the gaming machine 10 of the present embodiment, a game is played by striking a gaming ball (pachinko ball) from a launch device (not shown) toward the gaming area 32. The shot game balls run down the game area 32 while changing the rolling direction by turning members such as obstacle nails and windmills arranged at various places in the game area 32, and the common view starting gate 34 and the general winning opening 35 The start winning hole 36, the normal fluctuation winning device 37 or the special fluctuation winning device 38, or flows into the out port 39 provided at the bottom of the game area 32, and is discharged from the game area. Then, when the game ball wins in the general winning opening 35, the start winning opening 36, the normal fluctuation winning device 37 or the special fluctuation winning device 38, the number of winning balls according to the type of winning opening won by the payout control device 200. From the controlled dispensing unit, it is discharged into the upper tray or the lower tray of the front frame.

On the other hand, in the common view start gate 34, a gate switch 34a (see FIG. 4) including a non-contact type switch or the like for detecting gaming balls having passed through the common view start gate 34 is provided. When the gaming ball driven into the area 32 passes through the common drawing start gate 34, it is detected by the gate switch 34a and the common drawing variation display game is played.
In addition, a state in which the common drawing fluctuation display game can not be started, for example, a state in which the common drawing fluctuation display game is already played and the common drawing fluctuation display game is not ended, or the common drawing fluctuation display game hits If the game ball passes the common drawing start gate 34 when 37 is converted to the open state, the common drawing start memory is added (+1) if the number of common drawing start memories is less than the upper limit number. One figure starting memory will be memorized. The storage number of the common drawing start winning is displayed on the storage display for notification of the number of starting winnings of the LED display 53 of the batch display device 50.

Further, a hit determination random number value for determining hit of the hit of the common drawing variation display game is stored in the common drawing start memory, and the hit determination random number value matches the judgment value. In this case, the game result display game becomes a hit and a specific result aspect (specific result) is derived.
The common drawing fluctuation display game is to be executed by the fluctuation display unit (common drawing display) of the LED display unit 53 provided in the collective display device 50. The common drawing indicator is composed of an LED that indicates a hit in the lighting state as normal identification information (general drawing, normal symbol), and shows a deviation in the off state, and this LED is blinked to display normal identification information The variable display is performed, and the result is displayed by turning on or off the LED after a predetermined fluctuation display time has elapsed.

Note that, for example, a number, a symbol, a character pattern or the like may be used as the normal identification information, and this may be changed and displayed for a predetermined time and then stopped and displayed. If the stop display of this common drawing fluctuation display game becomes a specific result, it becomes a hit of the common drawing, and the pair of movable members 37b of the normal fluctuation winning apparatus 37 are opened for a predetermined time (for example, 0.3 seconds) It becomes a state. Thereby, the game ball easily wins the second starting winning opening inside the normal variation winning device 37, and the number of times the second special view variation display game is executed increases.
When the common drawing random number value extracted at the time of passage detection to the common drawing start gate 34 is a hit value, the normal symbol displayed on the common drawing display of the LED display unit 53 stops in the hit state and becomes the hit state. At this time, the normal fluctuation winning device 37 is in a state in which the movable member 37b is opened for a predetermined time (for example, 0.3 seconds) by driving the built-in common power solenoid 37c (see FIG. 4). It is converted, and winning of the game ball is permitted.

The winning balls to the start winning hole 36 and the winning balls to the normal fluctuation winning device 37 are respectively detected by the start hole 1 switch 36a and the start hole 2 switch 37a provided therein. The game ball that has won the start winning opening 36 is detected as the start winning ball of the first special view variation display game, and is stored within a predetermined upper limit number (for example, four) as a limit. The played game ball is detected as a start winning ball for the second special view variation display game, and is stored within a predetermined upper limit number (for example, four).
Also, when the start winning ball is detected, a big hit random number value, a big hit symbol random number value, and each variation pattern random number value are extracted, and the extracted random value is stored in the special view memory in the game control device 100 (see FIG. 4). Each area (a part of the RAM) is stored as a special map start memory within a predetermined number of times (for example, up to four times). Then, the storage number of the special view start storage is displayed on the storage display unit for notifying the start winning number of the batch display device 50 and is also displayed on the display device 41 of the center case 40.

The game control device 100 is a special display 1 display 51 or a special display 2 display 52 provided on the collective display 50 based on winning on the start winning opening 36 or the normal variation winning device 37 or their start storage. The first or second special view variable display game is played on the (variable display device).
The first special view variation display game and the second special view variation display game are performed by variably displaying a plurality of special symbols (special figure, identification information) and then displaying a predetermined result mode as a stop. In addition, a display special feature variation display game is executed in which a plurality of types of identification information (for example, numbers, symbols, character patterns, etc.) are variably displayed on the display device 41 in correspondence with each special pattern variation display game. ing.
Then, when the display mode of the special view 1 display 51 or the special view 2 display 52 becomes a special result mode as a result of the special view fluctuation display game, it becomes a big hit and a special gaming state (so-called, big hit state) ). Further, in response to this, the display mode of the display device 41 is also a special result mode. In this embodiment, when the stop result mode becomes the special result mode in the second variable display game of the special view 2 display, the stop result mode is special in the first variable display game of the special view 1 display The benefit (for example, the number of rounds) given to the player is set to be larger than that in the case of the result mode.

In the decorative special figure variation display game on the display device 41, for example, the decorative special symbol (identification information) composed of the above-mentioned numerals etc. is on the left (first special symbol), right (second special symbol), middle (third special The fluctuation display is started in the order of the symbols), and the symbols which are fluctuating after a predetermined time are sequentially stopped, and the result of the special view fluctuation display game is displayed. Further, in the display device 41, while performing the variable display game by the decoration special symbol corresponding to the special drawing start memory number, various effect display such as appearance of a character is performed to improve interest.
The special view 1 display 51 and the special view 2 display 52 may be separate displays or the same display, but each special view fluctuation display so as not to be executed independently or simultaneously. The game is displayed. Also, the display device 41 may use separate display devices or separate display areas in the first special view variable display game and the second special view variable display game, or use the same display device or display area. The decoration special feature variation display game is displayed so as not to be executed independently and simultaneously, though it is good.

In addition, the second special view variation display game is executed with priority over the first special view variation display game. That is, when there is a start memory of the first special view variation display game and the second special view variation display game, and the special view variation display game can be executed, the second special view variation display game is It is supposed to be run.
In addition, in the state where the first special view variation display game (the second special view variation display game) can be started, and the number of starting memories is 0, the starting winning opening 36 (or the normal variation winning device 37) When the game ball wins, the start memory is stored along with the generation of the start right, and the number of start memories is incremented by one, and based on the start memory, the first special view fluctuation display game The variable display game is started, and at this time, the number of starting memories is decremented by one.

On the other hand, the first special view variation display game (second special view variation display game) can not be started immediately, for example, the first or second special view variation display game is already played, and the special view variation display game is ended. When the game ball is won in the start winning opening 36 (or the normal variation winning device 37) when the game player is not in the state or in the special game state, the number of starting memories is 1 if the number of starting memories is less than the upper limit number. As a result, one start memory is stored. Then, when the number of starting memories becomes 1 or more, the first special view variation display game (the second special view variation display game) can be started (the previous special view variation display game is ended or in the special gaming state) At the end, the number of starting memories is decremented by one, and the first special view variation display game (the second special view variation display game) is started based on the stored starting storage.
In the following description, when the first special view variation display game and the second special view variation display game are not distinguished from one another, they are referred to simply as a special view variation display game.

  Although not particularly limited, the start opening 1 switch 36a in the start winning opening 36, the start opening 2 switch 37a in the normal fluctuation winning device 37, the gate switch 34a, the general winning opening switches 35a to 35n, and the count The switch 38a includes a non-contact type magnetic proximity sensor (hereinafter referred to as a proximity switch) which has a coil for magnetic detection and detects a game ball using a phenomenon that a magnetic field changes when metal approaches the coil. It is done.

And an output unit 130 having an output port and a driver, and a data bus 140 for connecting the CPU unit 110, the input unit 120, and the output unit 130.
The CPU unit 110 receives signals (starting winning detection signals) from a gaming microcomputer (CPU) 111 called an amusement chip (IC) and an interface chip (proximity I / F) 121 for a proximity switch in the input unit 120. It is equipped with an inversion circuit 112 consisting of an inverter that is logically inverted and input to the gaming microcomputer 111, and an oscillator such as a crystal oscillator, and generates a clock serving as a CPU operation clock or timer interrupt and a reference clock for random number generation circuits. An oscillator circuit (crystal oscillator) 113 or the like is included. The game control apparatus 100 and electronic components such as a solenoid and a motor driven by the game control apparatus 100 are supplied with a DC voltage of a predetermined level such as DC 32 V, DC 12 V, DC 5 V generated by the power supply apparatus 400 to be operable Be done.

The power supply apparatus 400 is a normal power supply having an AC-DC converter that generates the DC voltage of 32 V from an AC power supply of 24 V and a DC-DC converter that generates DC voltages of 12 V and 5 V lower than DC voltage of 32 V. It has a backup power supply unit 420 that supplies a power supply voltage to the RAM in the gaming microcomputer 111 at the time of a power failure, a power failure monitoring circuit and an initialization switch, and informs the game control apparatus 100 of the occurrence and recovery of the power failure And a control signal generation unit 430 that generates and outputs control signals such as a power failure monitoring signal, an initialization switch signal, and a reset signal.
In this embodiment, the power supply 400 is configured separately from the game control apparatus 100, but the backup power supply 420 and the control signal generator 430 are integrated on a separate board or with the game control 100, ie, main It may be configured to be provided on a substrate. Since the game board 30 and the game control apparatus 100 are to be replaced when changing the model, as in the embodiment, the backup power supply unit 420 and the control signal generation unit 430 are mounted on a substrate different from the power supply 400 or the main substrate. By providing it, it can be removed from the target of replacement and the cost can be reduced.

The backup power supply unit 420 can be configured of one large-capacity capacitor such as an electrolytic capacitor. The backup power supply is supplied to the gaming microcomputer 111 (particularly the built-in RAM) of the gaming control apparatus 100, and data stored in the RAM is held even during a power failure or even after the power is shut off. The control signal generation unit 430 monitors, for example, the voltage of 32 V generated by the normal power supply unit 410, detects the occurrence of a power failure when it falls below 17 V, for example, and changes the power failure monitoring signal. Output Also, at the time of power on or recovery from a power failure, a reset signal is output after a predetermined time has elapsed from that time.
The initialization switch signal is a signal generated when the initialization switch is turned on, and forcibly initializes information stored in the RAM 111C in the gaming microcomputer 111 and the RAM in the payout control device 200. . Although not particularly limited, the initialization switch signal is read when the power is turned on, and the power failure monitoring signal is repeatedly read in the main loop of the main program executed by the gaming microcomputer 111. The reset signal is a type of forced interrupt signal and causes the entire control system to be reset.

The gaming microcomputer 111 constitutes gaming control means for overall control of the game. Specifically, the gaming microcomputer 111 includes a CPU (central processing unit: microprocessor) 111A, a read only ROM (read only memory) 111B, a random read out random access memory (RAM) 111C, and a variable display game A random number generation circuit 111D is provided which generates a random number used to control a game such as the occurrence of a big hit.
The ROM 111B stores invariable information (program, fixed data, determination values of various random numbers, etc.) for game control in a non-volatile manner, and the RAM 111C stores a working area of the CPU 111A and storage areas of various signals and random values during game control. It is used as An electrically rewritable non-volatile memory such as an EEPROM may be used as the ROM 111B or the RAM 111C. Instead of using the CPU provided with the random number generation circuit 111D, a program may be used to generate random numbers.

Further, the ROM 111B stores, for example, a variation pattern table for determining a variation pattern that defines the execution time of the special view variation display game, the contents of the effect, the presence or absence of the reach state, and the like.
The variation pattern table is a table for the CPU 111A to determine a variation pattern by referring to the variation pattern random numbers 1 to 3 stored as start storage. Also, the fluctuation pattern table includes a falling fluctuation pattern table selected when the result is a falling, a jackpot fluctuation pattern table selected when the result is 15 R or 2 R, and the like. Furthermore, these pattern tables include a second half fluctuation pattern table and a first half fluctuation pattern table.

  Moreover, the reach (reach state) has a display device capable of changing the display state, and the display device derives and displays a plurality of display results at different times, and the plurality of display results are determined in advance. In the gaming machine 10 in which the gaming state is a gaming state (special gaming state) advantageous to the player when the special result mode is obtained, derivation is already made at a stage where a part of the plurality of display results is not yet derived and displayed. This refers to a display state in which the displayed display results satisfy the conditions for the special result mode. In addition, the reach state is deviated from the display condition which is the special result mode even when reaching the stage before the variable display control of the display device progresses and the display result is derived and displayed. There is no display mode. Then, for example, the reach state includes a state (so-called all-rotation reach) in which variable display is performed by a plurality of variable display areas while maintaining the state in which the special result mode is uniform. Further, the reach state is a display state at the time when display control of the display device progresses to a stage before the display result is derived and displayed, and is determined before the display result is derived and displayed. The display state in the case where at least a part of the display results of the plurality of variable display areas satisfies the condition to be the special result mode.

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

  And, this reach state includes a plurality of reach effects, and the possibility of deriving a special result aspect is different (there is a difference in reliability) as reach effects: normal reach, special 1 reach, special 2 reach, special 3 reach, Premier reach etc. are set. In addition, the degree of reliability is set to increase in the order of no reach <normal reach <special 1 reach <special 2 reach <special 3 reach <premier reach. Further, this reach state is included in the variable display mode at least when the special result mode is derived in the special view variable display game (when it is a big hit). That is, it may be included in the variable display mode in the case where it is determined that the special result mode is not derived in the special view variable display game (in the case of a disconnection). Therefore, the state in which the reach state occurs is a state in which the possibility of a big hit is higher than the case in which the reach state does not occur.

The CPU 111A executes a game control program in the ROM 111B to generate control signals (commands) for the payout control device 200 and the effect control device 300, and generate and output drive signals for solenoids and display devices. 10 Take control of the whole.
In addition, the game microcomputer 111 is a random pattern for the big hit determination of the special view variable display game, a random number for the big hit symbol for determining the symbol of the big hit, a change pattern in the special view change display game A fluctuation pattern random number for determining the execution time etc. of the fluctuation display game in the random number, a random number generation circuit 111D for generating a random number for collision judgment in the common drawing fluctuation display game, and an oscillation signal from the oscillation circuit 113 ( A clock generator (not shown) is provided to generate a clock for giving a timer interrupt signal of a predetermined cycle (for example, 4 milliseconds) to the CPU 111A and an update timing of the random number generation circuit 111D based on the original clock signal).

  In addition, the CPU 111A performs a plurality of fluctuation pattern tables stored in the ROM 111B in the starting opening switch monitoring process (step A1) in the special view game process (see FIG. 12) described later (step A1) and the special view routine process (step A9). Among them, one variation pattern table is acquired. Specifically, the CPU 111A is a game result (big hit or break) of the special figure variation display game, a probability state (normal probability state or high probability state) of the special figure variation display game as the current gaming state, the current game Select and acquire any one fluctuation pattern table from among a plurality of fluctuation pattern tables based on the operation state (normal operation state or short time operation state) of the normal fluctuation winning device 37 as a state, the number of starting memories, etc. Do.

It controls to drive the payout motor of and to pay out the winning balls. Further, the payout control device 200 drives the payout motor of the payout unit based on the ball lending request signal from the card unit, and performs control for dispensing the ball. Furthermore, the game control device 100 sends a firing permission signal or a power failure detection to the firing control device 210 that controls the firing motor 721 (see FIG. 6) that constitutes the bat firing device 72 (see FIG. 2) via the payout control device 200.

As the proximity I / F 121 has an input range of 7 V-11 V, it seems that the lead wire of the proximity switch is incorrectly shorted, the switch is disconnected from the connector, or the lead wire is disconnected and becomes floating. Abnormal state can be detected, and an abnormality detection signal is output.

  The output of the proximity I / F 121 is all supplied to the second input port 122 and read into the gaming microcomputer 111 via the data bus 140, and is also supplied from the main board 100 via the relay board 70 to the non-illustrated test shooting tester It is supposed to be. Further, among the outputs of the proximity I / F 121, detection signals of the start opening 1 switch 36a and the start opening 2 switch 37a are input to the gaming microcomputer 111 through the reversing circuit 112 in addition to the second input port 122. It is configured. The inverting circuit 112 is provided on the assumption that a signal from a micro switch or the like is input to the signal input terminal of the gaming microcomputer 111 and negative logic, that is, low level (0 V) is detected as an effective level. Because it is designed to

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

The circuit 124 has a function of removing noise from these input signals. Among the signals from the power supply device 400, the power failure monitoring signal and the initialization switch signal are once input to the first input port 123, and are taken into the gaming microcomputer 111 via the data bus 140. That is, they are treated as signals equivalent to the signals from the various switches described above. This is because the number of terminals for receiving external signals provided in the gaming microcomputer 111 is limited.

On the other hand, the reset signal RST from which the noise is removed by the Schmitt trigger circuit 124 is directly input to the reset terminal provided in the gaming microcomputer 111 and supplied to each port of the output unit 130.

The reset signal RST is not supplied to the ports 122 and 123 of the input unit 120. It is necessary to reset the data set in each port of the output unit 130 by the gaming microcomputer 111 immediately before the reset signal RST is input, but it is necessary to reset the data of the input unit 120 immediately before the reset signal RST is input. This is because the data read by the gaming microcomputer 111 from the port is discarded when the gaming microcomputer 111 is reset.

Output unit 130 is connected to data bus 140 and outputs a 4-bit data signal output to payout control device 200, a control signal (data strobe signal) indicating validity / invalidity of data, and a data strobe signal SSTB output to effect control device 300. , And a second output port 132 for generating an 8-bit data signal to be output to the effect control device 300.

Further, DC 12 V is supplied to the third driver 138 c that drives the segment lines of the batch display device 50. Since the second driver 138b for driving the digit line is for drawing out the digit line according to the display data, the power supply voltage may be either 12 V or 5 V. A dynamic drive system is achieved by flowing a current into the anode terminal of the LED through the segment line by the third driver 138c that outputs 12 V, and extracting the current from the cathode terminal through the segment line by the second driver 138b that outputs the ground potential. The power supply voltage flows to the LEDs sequentially selected in step S1 and is turned on.

  The reset signal RST generated by the control signal generation unit 430 of the power supply device 400 is a main control microcomputer 311, an image control microcomputer 312, a VDP 313, a sound source LSI 314, control circuits 332 to 335 for driving and controlling a lamp, a motor, etc. Are supplied to the amplifier circuits 337a and 337b for driving these to reset them. Further, in this embodiment, the general-purpose port of the image control microcomputer 312 is used to have a function of generating and supplying a reset signal to the VDP 313. As a result, the cooperation between the video control microcomputer 312 and the VDP 313 can be improved.

Next, rough game control performed in the game control device 100 and the effect control device 300 will be described.
The CPU 111A of the gaming microcomputer 111 of the gaming control apparatus 100 extracts the random determination value for hit determination of the common drawing based on the input of the detection signal of the game ball from the gate switch 34a provided in the common drawing start gate 34 The game is compared with the judgment value stored in the table to determine the hit / off of the common drawing fluctuation display game. Then, after the identification symbol is variably displayed for a predetermined period of time in the LED display unit 53, processing is performed to display a common drawing fluctuation display game which is stopped and displayed. If the result of the common drawing fluctuation display game is a hit, the special display result mode is displayed on the LED display unit 53 and the common electric solenoid 37c is operated to set the pair of movable members 37b of the normal fluctuation winning apparatus 37 for a predetermined time The release control is performed as described above (for example, 0.3 seconds).

In the present embodiment, when the result of the common drawing variation display game is a release, control is performed to display a result mode of the release on the LED display unit 53.
Further, the start winning combination (starting storage) is stored in the RAM 111C based on the input of the detection signal of the game ball from the starting opening 1 switch 36a provided in the starting winning opening 36, and the first special view fluctuation display is displayed based on the starting storage. A process for determining a hit-off of the first special-image variation display game is performed by extracting a random number value for jackpot determination of the game and comparing it with the determination value stored in the ROM 111B.
More specifically, the value of the random number generation circuit (random number counter) is latched in the random number latch register (not shown) every time the start winning is detected. Then, instead of latching the value of the random number generation circuit at the timing when the start winning is detected, the value is latched in the random number latch register at the rising edge of the clock signal immediately after detecting the starting winning. The latched value is a random number value at the timing when the start winning is detected, and the random number value is extracted as a jackpot determination random number value for the first special view fluctuation display game. Therefore, the RAM 111C functions as a start winning storage means.

The memory for starting is stored based on the input of the detection signal of the game ball from the starting opening 2 switch 37a provided in the normal fluctuation winning device 37, and based on the memory for starting, for the big hit judgment of the second special view fluctuation display game The random number value is extracted and compared with the determination value stored in the ROM 111B to determine the hit / off of the second special figure variation display game. Extraction of the jackpot determination random number value based on the detection of the start opening 2 switch 37a is also similar to that of the start opening 1 described above.
Then, the CPU 111A of the game control device 100 outputs control information (rendering control command) including the determination result of the first special view fluctuation display game or the second special view fluctuation display game to the effect control device 300. Then, after the identification symbol is variably displayed for a predetermined time on the special view 1 display 51 or the special view 2 display 52 of the collective display device 50, processing is performed to display a special view fluctuation display game in which stop display is performed.

On the other hand, based on the control signal from the game control apparatus 100, the effect control apparatus 300 performs a process of displaying a decoration special figure change display game corresponding to the special figure change display game on the display device 41. Further, the effect control device 300 performs processing of controlling the output of the sound from the speakers 19a and 19b, the light emission of the various LEDs, and the like based on the control signal from the game control device 100.
And, when the result of the special view fluctuation display game is a hit, the CPU 111A of the game control device 100 displays the special result mode on the special view 1 display 51 or the special view 2 display 52, and generates the special gaming state. Do the process of In the process of generating the special game state, for example, the CPU 111A performs control to open the opening / closing door of the special variation winning device 38 by the special winning opening solenoid 38b and to allow the game ball to flow into the special winning opening. .

Then, a predetermined number (for example, 10) of game balls win in the special winning opening or a predetermined time (for example, 25 seconds or 1 second) elapses from the opening of the special winning opening. One round is to open the special winning opening until it is done, and control (cycle game) to continue (repeat) the predetermined number of rounds (for example, 15 times or 2 times) is performed.
In addition, when the result of the special figure fluctuation display game is a release, control is performed to display a result mode of the deviation on the special figure 1 display 51 or the special figure 2 display 52.
In addition, the game control apparatus 100 can generate the probability change state as the game state after the end of the special game state based on the result mode of the special figure variation display game.
The probability change state is a state (high probability state) in which the probability of being hit in the special figure variation display game is higher than that in the normal probability state. In addition, even if it becomes a definite change state based on the result aspect of the special figure fluctuation display game of the 1st special figure fluctuation display game and the 2nd special figure fluctuation display game, the 1st special figure fluctuation display game and the 2nd special figure fluctuation Both display games are in a state of probability variation.

In addition, the game control device 100 can generate the time saving state as the gaming state after the end of the special game state, based on the result mode of the special figure variation display game.
In the short time state, control is performed to set the common drawing fluctuation display game and the normal fluctuation winning device 37 in the short time operation state. Specifically, in the time saving state, control is performed so that the execution time of the above-described common view fluctuation display game becomes a second fluctuation display time shorter than the first fluctuation display time (for example, 10 seconds is 1 second) ), Whereby the number of times of opening of the normal fluctuation winning device 37 per unit time is controlled to be substantially increased.
Also, in the time saving state, when the regular drawing fluctuation display game hits and the normal fluctuation winning device 37 is released, the opening time is set to a second opening time longer than the first opening time in the normal state. (For example, 0.3 seconds is 1.7 seconds). Moreover, in the time saving state, the number of times of opening of the normal fluctuation winning apparatus 37 is not the number of first opening of one time, but the plural times of two or more times (for example, It is set to the second open frequency of 3). Hereinafter, such control mode is referred to as a common power support.

In addition, the control which makes the execution time of a common drawing fluctuation display game 2nd fluctuation display time (for example, 1 second), and the opening mode of the normal fluctuation winning a prize device 37 open time 2nd opening time (for example, 1.7 The second control (for example, three times) may be performed for the control of setting the number of opening times to one hit result of the common drawing variation display game to the second), or only one of them may be performed. It is good. Further, in the time-saving operation state, control may be performed so that the probability of being a hit result of the common view variation display game is higher than that in the normal operation state.
Thus, the game ball easily wins the normal fluctuation winning device 37, and the start of the second special view fluctuation display game becomes easy.
It should be noted that the probability variation state and the common drawing variation display game and the time variation operation status of the normal variation winning device 37 can be generated independently of each other, and both can be generated simultaneously or only one can be generated. It is possible.

In this embodiment, one of two types of motor control signals is generated by the setting signals SET1 and SET2 according to the pulse motor (stepping motor) to be used, and the solenoid control signal is set so as not to be generated.

Hereinafter, the process executed by the gaming microcomputer (gaming microcomputer) 111 of the gaming control apparatus 100 that executes the above-described gaming control will be described. The control processing by the gaming microcomputer 111 mainly includes the main processing shown in FIGS. 9 and 10, and the timer interrupt processing shown in FIG. 11 which is performed in a predetermined time cycle (for example, 4 msec).
First, the main processing will be described. The main process is started by turning on the power. In this main process, as shown in FIG. 9, an interrupt vector setting process (step S1) is performed to set the vector address of the jump destination to be executed when an interrupt occurs after performing the process (step S1) to prohibit interrupts. S2) Stack pointer setting processing (step S3) for setting a stack pointer which is the top address of an area for saving values of registers etc when an interrupt occurs (step S3), interrupt mode setting processing for setting a mode of interrupt processing (step S4) )I do.

  Next, in order to wait for the program of the payout control device (dispensing substrate) 200 to be started normally, a wait of, for example, 4 msec is performed (step S5). As a result, when the power is turned on, the game control device 100 temporarily sends a command to the payout control device 200 before the payout control device 200 starts up, and the payout control device 200 avoids dropping the command. be able to. After that, the access permission of the readable and writable RWM (read / write memory: RAM 111C) such as the RAM or EEPROM is permitted, and all the output ports are turned off (no output) (steps S6 and S7). Also, the serial port ((a port provided in advance in the gaming microcomputer 111) is not used in this embodiment because it is in parallel communication with the payout control device 200 and the effect control device 300. A process is performed (step S8).

  Subsequently, it is determined whether or not the initialization switch in the power supply device 400 is turned on (step S9). Here, if it is determined that the initialization switch is off (step S9; No), it is checked whether the value of the power failure inspection area 1 in the RWM is normal power failure inspection area check data (step S10), and if normal. (Step S11; Yes), it is checked whether the value of the power failure inspection area 2 in the RWM is normal power failure inspection area check data (step S12). Next, if the value of the power failure inspection area 2 is normal (step S13; Yes), the checksum of a predetermined area in the RWM is calculated (step S14), and the calculated checksum and the checksum at the time of power failure are calculated. After comparison (step S15), it is determined whether they match (step S16). And when it corresponds (step S16; Yes), it transfers to step S17 of FIG. 10, and performs the process in the case of recovering normally from a power failure.

In addition, when it is determined that the initialization switch is on (step S9; Yes), or when it is determined that the check data of the power failure inspection area is not normal data (step S11; No or step S13; No), the checksum Is determined not to be normal (step S16; No), the process proceeds to step S24 in FIG. 10 to perform initialization processing.
In step S17 of FIG. 10, all the power failure inspection areas are cleared, the checksum area is cleared (step S18), and the area relating to error or fraud monitoring is reset (step S19). Next, the area storing the gaming state in the RWM is checked to determine whether the gaming state is in the high probability state (step S20). Here, when it is determined that the probability is not high (step S20; No), steps S21 and S22 are skipped and the process proceeds to step S23.

  If it is determined in step S20 that the probability is high (step S20; Yes), the ON information is saved in the high probability notification flag area (step S21). The error indicator) ON (lighting) data is saved in the segment area (step S22). Then, a process (step S23) for transmitting to the effect control device 300 a command at the time of power restoration corresponding to the process number prepared to rationally execute the special view game process described later is performed, and the process proceeds to step S29. .

  On the other hand, when jumping from steps S9, S11, S13 and S16 to step S24, all work areas before the access prohibited area are cleared (step S24), and all stack areas after the access prohibited area are cleared. (Step S25) The initial value at power on is saved in the area to be initialized (step S26). Then, the time value of the period during which the external information on the RWM clear is output is set (step S27), the command at power on is transmitted to the effect control device 300 (step S28), and the process proceeds to step S29. In step S29, processing for activating a CTC (Counter / Timer Circuit) circuit that generates a timer interrupt signal and a random number update trigger signal (CTC) in the gaming microcomputer 111 (clock generator) is performed.

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

After the CTC activation process of step S29, the random number generation circuit 111D is activated and set (step S30). Specifically, setting of a code (designated value) for activating the random number generation circuit 111D to a predetermined register (CTC update permission register) in the random number generation circuit is performed by the CPU 111A. Then, when the power is turned on, the values of predetermined registers (soft random number registers 1 to n) in the random number generation circuit are set to corresponding various initial value random numbers (random numbers determining big hit symbols (big hit symbol random number 1, big hit symbol random number 2) After saving in a predetermined area of the RWM as an initial value (start value) of a random number (performing random number) for determining a hit of a common drawing (step S31), an interrupt is permitted (step S32). The random number generation circuit 111D in the CPU 111A used in the present embodiment is configured to change the initial value of the soft random number register every time the power is turned on. Therefore, this value is used as the initial value (start value) of various initial value random numbers. By doing this, it is possible to break the regularity of the random numbers generated by the software, and it is possible to make it difficult for the player to obtain an incorrect random number.
Subsequently, an initial value random number updating process (step S33) is performed to update the values of various initial value random numbers and break the regularity of the random numbers.

  After the initial value random number update process of step S33, the number of times the power failure monitoring signal input from the power supply 400 is read and checked via the port and data bus is set (step S34), and the power failure monitoring signal is ON. It is determined whether there is any (step S35). If the power failure monitoring signal is not ON (step S35; No), the process returns to the initial value random number updating process (step S33). That is, when a power failure has not occurred, the initial value random number update processing and the check (loop processing) of the power failure monitoring signal are repeated. By permitting the interrupt (step S32) before the initial value random number update process (step S33), when the timer interrupt occurs during the initial value random number update process, the interrupt process is preferentially executed, and the timer interrupt is performed. By waiting for the initial value random number updating process, it is possible to avoid the pressure on the interrupt process.

  In addition to the main processing, there is also a method of performing initial value random number update processing in the timer interrupt processing in addition to the main processing in the above-described step S33. In order to prevent the value random number update process from being performed, when performing the initial value random number update process in the main process, it is necessary to prohibit the interrupt and then update and cancel the interrupt. There is no problem in canceling the interrupt before the initial value random number update process if the initial value random number update process in the timer interrupt process is not performed but is performed only in the main process, and the main process It has the advantage of being simplified.

  If the power failure monitoring signal is ON (step S35; Yes), it is determined whether the power failure monitoring signal remains ON for the number of checks set in step S34 (step S36). Then, if the power failure monitoring signal is not ON for the number of checks (step S36; No), the process returns to the determination (step S35; Yes) whether the power failure monitoring signal is ON. Also, if the power failure monitoring signal is still ON for the number of checks (step S36; Yes), that is, if it is determined that a power failure has occurred, processing for temporarily prohibiting an interrupt (step S37), all A process (step S38) of outputting the OFF data to the output port is performed.

  Thereafter, the power failure recovery inspection region check data 1 is saved in the power failure recovery inspection region 1 (step S39), and the power failure recovery inspection region check data 2 is saved in the power failure recovery inspection region 2 (step S40). Furthermore, after performing the process of calculating the checksum at the time of the power cut off of the RWM (step S41) and the process of saving the checksum (step S42), the process of prohibiting the access to the RWM (step S43) Wait for the power to the gaming machine to shut off. As described above, by saving check data in the power failure recovery inspection area and calculating a checksum at the time of power shutdown, it is determined whether the information stored in the RWM is correctly backed up before the power shutdown. It can be determined when the power is turned on again.

Next, timer interrupt processing will be described using the flowchart of FIG.
The timer interrupt process shown in FIG. 11 is started by inputting a periodic timer interrupt signal generated by the CTC circuit in the clock generator to the CPU 111A.
When the timer interrupt process is started, a process of saving the register (step S51) is performed to transfer the value held in the predetermined register to the RWM. In the Z80-based microcomputer used as a gaming microcomputer in this embodiment, the process can be replaced by saving the value held in the front register to the back register. Next, input processing from various sensors (starting opening 1 switch 36a, starting opening 2 switch 37a, gate switch 34a of common drawing, count switch 38a, etc.), ie, input processing for reading the state of each input port (step S52) )I do. Then, on the basis of the output data set in the various processes, an output process (step S53) is performed to control the drive of an actuator such as a solenoid (large winning opening SOL38b, Fuden SOL37c).

  Next, a command transmission process (step S54) for outputting a command set in the transmission buffer in various processes to the effect control device 300, the payout control device 200, etc. (step S54), a random number update process 1 (step S55), a random number update process 2 (step Perform S56). After that, monitoring whether or not there is an input of a normal signal from the start port 1 switch 36a, the start port 2 switch 37a, the gate switch 34a of the common drawing, the winning port switch 35a ... 35n, and the count switch 38a A winning opening switch / error monitoring process (step S57) is performed to determine whether the front frame and the glass frame are open. In addition, special figure game processing (step S58) which performs processing concerning a special figure fluctuation display game, and common drawing game processing (step S59) which performs processing concerning a common drawing fluctuation display game is performed.

  Next, segment LED editing processing (step S60) provided in the gaming machine 10 to drive the segment LED for displaying the special view fluctuation game display and various information related to the game to display desired content (step S60), magnetic sensor switch 61 In addition, a magnet fraud monitoring process (step S61) is performed to check the detection signal from the vibration sensor switch 62 and determine whether there is an abnormality. Then, an external information editing process (step S62) is performed in which signals to be output to various external devices are set in the output buffer. Subsequently, processing for clearing the interrupt request and declaring the end of the interrupt (step S63) is performed, and processing for recovering the data of the register saved in step S51 (step S64) is performed, and processing for permitting the interrupt ( Step S65) is performed to end the timer interrupt process.

Next, the details of the special-figure game process (step S58) in the above-described timer interrupt process will be described with reference to FIG.
In the special view game process, the monitoring of the input of the starting opening 1 switch 36a and the starting opening 2 switch 37a, the control of the entire processing related to the special view variation display game, and the setting of the display of the special view are performed.
As shown in FIG. 12, in the special view game process, first, a start switch monitoring process (step A1) is performed to monitor winning of the start opening 1 switch 36a and the start opening 2 switch 37a.
In this starting opening switch monitoring process, when there is a winning of a game ball in the starting winning opening 36 and the normal variation winning device 37 forming the second starting winning opening, various random numbers (big hit random numbers etc.) are extracted, and based on the winnings A game result prior determination is performed in which the game result based on the winning is determined in advance before the start of the special view variation display game.
In the present embodiment, the value of the random number generation circuit (random number counter) is latched in the random number latch register (not shown) every time the start winning combination is detected by the start opening 1 switch 36a or the start opening 2 switch 37a. Then, instead of latching the value of the random number generation circuit at the timing when the start winning is detected, the value is latched in the random number latch register at the rising edge of the clock signal immediately after detecting the starting winning. Further, the value to be latched is a random number value at the timing when the start winning is detected, and the random number value is extracted as a random number value for jackpot determination of the first special view fluctuation display game or the second special view fluctuation display game There is.

Following the start switch monitoring process (step A1), the count switch monitoring process (step A2) is performed. In the count switch monitoring process, a process of monitoring the count number of the count switch 38a provided in the special variation winning device 38 is performed.
Next, the special figure game processing timer is updated (-1), and it is checked whether the game processing timer has timed up (step A3), and the special figure game processing timer has timed up (step A4; If it is determined as Yes, a special figure game sequence branch table to be referred to for branching to a process corresponding to the special figure game process number is set in a register (step A5), and the special figure game is executed using the table. The process (step A6) of acquiring the branch destination address of the process corresponding to the process number is performed.

Then, after the processing (step A7) for saving the return address after the end of the branching processing to the stack area, the game branching processing (step A8) is performed according to the game processing number.
If the game processing number is "0" at step A8, the start of change of the special view change display game is monitored, and the setting of change start of the special view change display game and the setting of the effect, and the processing during the special view change A special drawing routine processing (step A9) is performed to set information necessary for the execution.
In addition, when the game processing number is “1” in step A8, the special figure change processing for setting the stop display time of the special view, setting of information necessary for performing the special view display process, etc. (Step A10) is performed.
Furthermore, if the game processing number is "2" at step A8, if the game result of the special view variation display game is a big hit, the setting of the fanfare command according to the type (2R big hit or 15R big hit), Set the fanfare time according to the big winning opening opening pattern of each big hit (2R big hit or 15R big hit), set the information necessary for performing fan fare / in-interval processing, etc. Process during display (step A11) Do.

Also, if the game processing number is "3" at step A8, the setting of the opening time of the special winning opening and the updating of the number of opening, the setting of information necessary for performing the special winning opening open processing The fan fare / in-interval process (step A12) is performed.
If the game processing number is "4" at step A8, an interval command is set if the big hit round is not the final round, while if it is the final round, a big hit end screen command is set, A special winning opening open processing (step A13) is performed to set information necessary for performing the winning opening residual ball processing.

If the game processing number is "5" in step A8, if the big hit round is the final round, processing to set the time for the remaining balls in the big winning opening to be discharged, and the big hit end processing A special winning opening remaining ball process (step A14) is performed to set information necessary for the execution.
If the game processing number is "6" in step A8, a big hit end process (step A15) is performed to set information necessary for shifting to the special view routine process (step A9).

And after preparing the table for controlling the fluctuation of the special figure 1 display 51 or the special figure 2 display 52 (step A16), the symbol variation control concerning the special figure 1 display 51 or the special figure 2 display 52 A process (step A17) is performed to end the special-figure game process.
On the other hand, if it is determined in step A4 that the special figure game processing timer has not timed out (step A4; No), the process proceeds to step A16 to perform the subsequent processes.
As described above, in the present embodiment, the game control device 100 functions as the variable display game execution means and the special game state control means.

Next, control executed by the main control microcomputer (1st CPU) 311 of the effect control device 300 will be described.
The control process by the main control microcomputer 311 includes a 1st main process shown in FIG. 13 and a command reception interrupt process performed every predetermined time (for example, every 2 msec). In the 1st main process, control of the entire program is performed.
[1st main process of effect control device]
As shown in FIG. 13, in the 1st main processing, first, processing for inhibiting an interrupt (step B1) is performed, then processing for clearing the RAM to 0 (step B2) is performed, and processing for initializing the 1st CPU 311 (step B3). )I do.
Next, a process of setting an initial value in the RAM (step B4) is performed, and a random number initialization process (step B5) is performed. Thereafter, processing for activating timers for various interrupts is performed (step B6), and interrupts are permitted (step B7). Thereafter, the main control microcomputer 311 performs main loop processing steps B8 to B18.

In the main loop process, first, a process (step B8) of clearing the watchdog timer (WDT) is performed. Then, an input process (step B9) from the effect operation button SW 25a is performed, and a game control command analysis process (step B10) is performed.
In this game control command analysis process, it is determined whether or not the game-related command transmitted from the game control apparatus 100 has been correctly received, and if it has been correctly received, the command is determined. One command transmitted from the game control device 100 is configured by a pair of data of a first command (MODE) and a second command (ACTION).

Then, when the combination of the received first command (MODE) and the second command (ACTION) is not inconsistent (for example, when received in the order of MODE → ACTION), it is determined that the command is correctly received, and the first command (MODE) If the combination of the) and the second command (ACTION) is inconsistent (for example, in the order of ACTION → ACTION or in the order of MODE → MODE → MODE), it is determined that the reception of the command is abnormal. .
Subsequently, after the test mode process (step B11) is performed, the scene control process (step B12) is performed to perform the process related to the special figure variation display game. The scene control process (step B12) will be described in detail later.

  Thereafter, a game machine error monitoring process (step B13) for monitoring occurrence of an error such as opening of the front frame (inner frame) 12 or the glass frame 15 (step B13) A sound control process (step B15) which is a process related to the output of sound (a drive process of the speakers 19a and 19b) and a decoration control process (step B16) which is a process related to control of the frame decoration device 18 provided on the front frame are performed. The motor / SOL control processing (step B17) related to the control of the panel effect motor / SOL control circuit 334 for driving the prizes and the like provided in the center case 40 (step B17), the variation mode (variation pattern) of the special figure variation display game, etc. The random number updating process (step B18) for updating the random numbers to determine the details of the process is performed, and the process returns to the process (step B8) for clearing the watchdog timer.

  FIG. 14 shows an example of a specific procedure of the scene control process (step B12) in the 1st main process shown in FIG. In the scene control process, first, it is determined whether the test mode is in progress (step B61). If the test mode is in progress (step B61; Yes), the scene control process is ended. If the test mode is not in progress (step B61; No), it is determined whether a scene change command has been received (step B62).

  The scene change command is various commands regarding the game transmitted from the game control device 100 to the effect control device 300. When this scene change command is received (step B62; Yes), the gaming state to be updated (the current gaming state) is acquired (step B63), and it is determined whether it is a valid command (step B64). In the determination as to whether the received command is a valid command (step B64), it is determined whether the received scene change command is valid for the acquired current gaming state. Then, if it is a valid command (step B64; Yes), the received command is saved (step B65), the presentation request flag is set (step B66), and the branch processing by the command identifier of the received command (step B67) )I do.

On the other hand, when the scene change command is not received (step B62; No) or when it is not a valid command (step B64; No), the branch processing (step B67) is performed by the command identifier of the received command. In this case, the branch is performed with the identifier of the most recent valid command.
In branch processing by the command identifier (step B67), processing to be executed is selected based on the received command. When the power on command is received, the power on process (step B68) is performed to perform the necessary process at the power on. When a power failure recovery command is received, a power failure recovery (other than customer waiting) processing (step B69) is performed to perform processing necessary for power failure recovery. When a customer waiting demo command is received, a customer waiting process (step B70) is performed to perform processing relating to the display of the customer waiting demo.

  When the variation pattern command is received, a variation processing (step B71) is performed to perform processing relating to the execution of the decorative figure variation display game. In the during-variation process (step B71), setting of information necessary to play the decorative-special-figure fluctuation display game is performed. In the setting of the information necessary to play this decorative special figure variation display game, for example, information (whether it is a big hit, mode information, variation pattern information, etc.) included in the variation pattern command transmitted from the game control device 100 Based on the setting of the effect (such as fluctuation pattern and fluctuation time). Further, when the symbol stop command is received, symbol stop processing (step B72) is executed, which is processing for stopping the variable display of the identification information in the decorative special game variable display game and displaying the result mode. In this symbol stopping process (step B72), the setting of the stop display time of the result in the decoration special figure change display game is performed.

  If a fanfare command has been received, fanfare processing (step B73), which is processing relating to the start of the special gaming state, is performed. Further, when the large entry open n-th command is received, the in-round process (step B74) which is a process related to the round game is performed. Also, when an interval command is received, an interval process (step B75), which is a process related to an interval between rounds, is performed. When an ending command is received, an ending process (step B76) which is a process related to the end of the special gaming state is performed.

After performing the above-described each process selected by the branch process (step B67) using the command identifier, the process based on the command not immediately reflected in the image is performed. As this processing, first, symbol command reception processing (step B77) is performed to perform processing based on the decoration special drawing command including information on the stop design of the special drawing fluctuation display game, and the pending number command including information on increase / decrease of starting memory A pending number command reception process (step B 78) is performed to perform processing based on the special figure 1 pending number command, the special figure 2 pending number command).
Furthermore, a pre-reading effect command (starting-up part winning effect command) transmitted by pre-reading effect determination processing (FIG. 16) which determines in advance the special drawing change display game result etc. based on the start memory before executing the special view change display game. Then, a preread effect command reception process (step B79) is performed to perform a process based on the start opening prize effect symbol command). Thereafter, probability information command reception processing (step B80) is performed to perform processing based on a probability information command (probability information command (low probability, high probability)) including information on probability states.
In pre-reading effect command reception processing of step B79, the processing which changes the indicatory feature (pending design) of starting memory according to the pre-reading result is done.

Next, the update timing of the random number generated by the random number generation circuit 111D built in the gaming microcomputer 111 (see FIG. 3), which is a feature of the control system of the gaming machine of this embodiment, The relationship with the output timing (strike launch timing) of the launch control signal generated by the control circuit 211 (see FIG. 8) will be described. In the embodiment described below, it is assumed that the random number generation circuit 111D updates the random number by +1 at a predetermined update timing by the counter method. In addition, instead of +1, -1 may be updated.
In the control system of the conventional game machine, no consideration was given to the relationship between the update timing of the big hit random number and the launch timing of the bat. Therefore, there may occur a moment when the update timing of the random number and the firing timing of the hitting ball are synchronized within a relatively short period, and by continuing the continuous firing, the random value at the time of firing reappears after a predetermined time The sequence of random number values for each shot until firing is always constant, and there is a disadvantage that it is possible to shoot at the big hit timing using synchronization.

Specifically, for example, as shown in FIG. 15 (A), the update range of the random number generation circuit of the big hit random number (special figure variation display game and common drawing variation display game) is set to 0 to 9 and 1 ms (milliseconds) While updating is performed each time, as shown in FIG. 15 (B), when the firing period of the bat is set to 12 ms (pattern 1) or 11 ms (pattern 2), the big hit random number makes a round in 10 ms. It will be. That is, the update period of the random number is 10 ms.
Therefore, as shown in FIG. 16, in the case of pattern 1 (emission cycle 12 ms), the emission timing and the appearance timing of the big hit random number coincide once in 5 times of emission (60 times of update). That is, it synchronizes every 60 ms. Further, in the case of pattern 2 (emission cycle 11 ms), the emission timing and the appearance timing of the big hit random number coincide once in 10 times of emission (the number of updates is 110). That is, it synchronizes every 110 ms.

FIG. 17 shows a table showing the relationship between the random number update period and the firing period under the conditions described above. Here, "12" in the case where 1 ms of the firing cycle 12 ms of pattern 1 is a unit time is "2 × 2 × 3" when represented using a prime number, and 1 ms of a random number updating cycle 10 ms is a unit time “10” in the case is “2 × 5” when expressed using a prime number. Then, multiples of this unit time are compared. The unit time may not be 1 ms. From FIG. 17, it can be seen that the synchronization interval between firing and random numbers is represented by the least common multiple of the random number update cycle and the firing cycle. That is, in order to increase the synchronization interval between the firing and the random number, it is sufficient to increase the least common multiple of the random number updating period and the firing period.
By the way, if it is assumed that the synchronous interval of firing and random number is 12 hours or more, if the operating time of the day in the game arcade is 12 hours, even if the player plays the game all day, the random number appeared at a certain firing timing Since it does not appear again on the same day, it can certainly prevent the jackpot shooting using the synchronization of firing and random numbers. However, in order to prevent acquisition of the same random number consecutively, updating of the random number needs to be performed at least once every several milliseconds, so the synchronization interval between firing and random number is 12 hours or more In this case, it is necessary to make the update range of the random number extremely large, which causes an increase in the size of the random number generation circuit and a reduction in the efficiency of using the RAM.

  Therefore, the inventor examined the minimum time between the firing interval and the random number synchronization interval. As a result, in order to reduce the update range of the random number while surely preventing the big hit shooting using the synchronization of the launch and the random number, the sync interval of the launch and the random number is slightly smaller than the longest one of the variation times of the display game We came to the conclusion that we should do it longer. Since the variation time of the variation display game is determined for each effect, if there is a player who recognizes the synchronization interval, there is a risk that the synchronization interval may be known based on that time, and the synchronization between firing and random numbers When the interval is set to be shorter than the fluctuation time of the fluctuation display game, the same big hit random number is generated again during the fluctuation time of the fluctuation display game in which the big hit occurs. This is because the probability of acquiring the jackpot random number can be increased.

  In the gaming machine of the present embodiment, the oscillation used in the emission control device for determining the emission period so that the synchronization interval between the emission and the random number can be set longer than the longest one of the fluctuation time of the fluctuation display game. The oscillation frequency of the crystal oscillator 212 (see FIG. 7) as a means is selected according to the update period of the random number. Hereinafter, a specific selection method will be described. The emission control circuit 211 in FIG. 7 includes a drive circuit that applies a voltage to a crystal oscillator to cause oscillation, so that a unit including the crystal oscillator and its drive circuit can also be regarded as an oscillation means.

FIG. 18A shows the formula of the firing cycle of the launch control device and the number of shots per minute (the number of revolutions of the firing motor 721) of the gaming machine of this embodiment. Here, the oscillation frequency of the crystal oscillator 212 is PF, and the division ratio of the divider circuit 222 in the oscillation control circuit 220 (see FIG. 8) for dividing the oscillation signal by the oscillator is PC. The firing motor used in the present embodiment is a pulse motor, and the number of pulses required to make one turn of the pulse motor is PN. In addition, it is assumed that the launch control device 210 is configured to launch one game ball when the launch motor 721 is rotated once. Then, the firing cycle is represented by firing cycle = PN × PC / PF, and the number of revolutions of the firing motor (rpm), that is, the number of firings per minute is represented by the number of firings (per minute) = T × PF / PN × PC. Be done. Note that T is 1 minute, that is, 60 seconds.
Therefore, the firing motor as the firing means performs a unit operation of firing one gaming ball when a drive signal of a predetermined number of pulses is applied, and the firing cycle of the firing means is the number of pulses and the crystal to be used. The frequency is determined according to the oscillation frequency specific to the oscillator (oscillation means) and the division ratio of the divider circuit.

The number of firings per minute of the firing control device in a pachinko gaming machine is usually within 100 times. Therefore, if the dividing ratio PC of the dividing circuit 222 is set to 12296, for example, the figure from among the crystal oscillators 212 of a plurality of types of commercially available oscillation frequencies so that the number of firings is 100 or less. As shown in 18 (B), if the frequency is 4.086407 (MHz), 4.084101 (MHz), 3.842500 (MHz), 4.034625 (MHz), 4.098666 (MHz) The firing cycle and the number of shots per minute have values as shown in the middle and right columns of the table of FIG. 18B, respectively. The values shown in the middle column and the right column of the table in FIG. 18B are approximate values. For example, the value in the middle column of (1) is exactly 200 × 12296 / 4.086407 ≒ 601.50. It becomes. Other values are also the same.
On the other hand, as shown in FIG. 19A, the update range (the size of the random number) of the random number in the random number generation circuit 111D in the gaming CPU 111 constituting the gaming control apparatus 100 is “0 to 65535 (2 of 16 If the update time is set to 100 ns (nanoseconds) once using, for example, a 10 MHz frequency of 1/2 of the system clock of 20 MHz, the update period of the random number is as shown in FIG. Since it is expressed by the magnitude / frequency of the random number, the update period of the random number is 6.5536 ms according to this equation.

The inventor considered to quantify the optimal range of the firing timing and the synchronization period TL of the random number. However, when the oscillation frequency or the random number update time as described above is selected, as shown in FIG. 18B and FIG. 19B, the firing period and the update period have values with decimal points. I will. Therefore, as shown in FIG. 20A, the denominator and the numerator can be treated as integers by expressing the firing period and the random number update period as a fraction that is a ratio of integers.
Specifically, the random number update period is represented by m / M, and the emission period is represented by n / N. Here, m and M are integers which are prime to each other. Similarly, n and N are integers that are relatively prime to each other. When 1 / MN (seconds) is treated as a unit time, as shown in FIG. 20B, the synchronization period TL can be conveniently expressed by a multiple of the unit time. If m / M and n / N are in the state of irreducible fractions, then m and M are necessarily "integers prime to each other".

Next, integers Nm and Mn are obtained by multiplying m / M and n / N respectively by the numerical value of MN. Then, when taking this integer Nm and the least common multiple Lcm (Nm, Mn) of Mn, it can be seen that Lcm (Nm, Mn) is MN times the firing timing and the synchronization period TL of the random number. Therefore, by dividing Lcm (Nm, Mn) by the MN value, as shown in FIG. 20B, the value of the original synchronization period TL can be obtained. Furthermore, this upper-stage equation can be transformed into the middle and lower stages using the function Gcd representing the greatest common divisor.
Therefore, under the condition that m and M and n and N are mutually prime integers, the maximum value X of the fluctuation time of the fluctuation display game among the values of TL obtained as described above (for example, Choosing a value greater than 65 seconds) can prevent big hit shooting using fire and random synchronization. The synchronization period TL between the firing timing and the random number may be a relatively long time, such as one hour or 12 hours, as long as it is larger than the value of the equation shown in FIG. If the optimum range of the period TL is quantified, the inequality shown in FIG. 20C can be obtained.

Next, a specific setting example that satisfies the above inequality will be described with reference to FIG.
Here, although not particularly limited, the random number generation circuit 111D is operated in a counter mode that counts up one by one from "0", and the magnitude of the random number m is 65536 (= 2 ¹⁶ ), It is assumed that it is counted up to 2 ¹⁶ -1) (note that the random number generation circuit 111D may count up from "1" to 65,536 one by one, not from "0"). Further, the frequency M of the clock for operating the random number generation circuit 111D is set to 10 MHz. In FIG. 21, 2 ^{^} 16 means 2 16 (= 2 ¹⁶ ), and 10 ^{^} 7 means 10 7 (= 10 ⁷ ).

On the other hand, as for the hitting and launching apparatus, a pulse motor which makes one rotation with 200 pulses was used as a launching motor. In addition, the frequency control circuit 222 (see FIG. 8) of the oscillation control circuit 220 (see FIG. 8) has the frequency N of the quartz oscillator for emission control set to 4.098666 MHz so that the emission period is 60 ms (100 emissions per minute). The division ratio of was set to 12296. As a result, 19637600 seconds were obtained as the synchronization period. This value satisfies the inequality shown in FIG. 20C because the maximum fluctuation time of the fluctuation display game is of course sufficiently longer than 12 hours (43,200 seconds) of the business day of the day, and the firing and the synchronization of random numbers are synchronized. It is possible to reliably prevent the shooting of the jackpot using the. Further, since the random number update range of 65,536 (= 2 ¹⁶ ) is a range conventionally implemented, it does not increase the burden on the gaming control CPU.
Note that mn / Gcd (mN, nM) in the right term of the inequality shown in FIG. 20C is an integer in which m and n are relatively prime, and M and N are also mutually prime integers. Since the greatest common divisor of the product value mN and the product value nM is only “1”, it can be expressed simply by mn. That is, the inequality in FIG. 20C showing the condition of the synchronization period TL is X ≦ TL = mn (X is the maximum fluctuation time of the fluctuation display game).

  Furthermore, the inventor of the present invention has determined five values (4.086407 MHz, 4.084101 MHz, 3.842500 MHz, 4.842101 MHz) as shown in the left column of FIG. 18 (B) as the frequency N of the crystal oscillator for emission control. Assuming that 034625 MHz and 4.098666 MHz), the synchronization interval TL between the update timing of the random number and the emission timing under the same conditions as above, and the number of updates of the random number within the synchronization interval and the number of hits were calculated. As a result, calculated values as shown in FIG. 22 were obtained. In FIG. 22, the equations (2 ^ 2 * 5 * 7 * 19 * 29 * 53, etc.) under the frequency, synchronization interval, random number update frequency, and number of firings are obtained by factoring each value into an equation It is a representation.

As shown in FIG. 22, since the synchronization interval is sufficiently longer than the maximum fluctuation time of the fluctuation display game, the two from the top (when using 4.086407 MHz and 4.084101 MHz as the frequency N of the crystal oscillator) and the bottom are sufficiently long. It turns out that it is applicable. In addition, the third from the top (when using 3.842500 MHz as the frequency N of the quartz crystal) is not applicable because the synchronization interval is about 20 seconds and shorter than the maximum fluctuation time of the fluctuation display game.
Furthermore, the fourth from the top (when using 4.034625 MHz as the frequency N of the quartz crystal), the synchronization interval is about 102 seconds, so it is applicable if the maximum fluctuation time of the fluctuation display game is 65 seconds. However, this is not applicable to a gaming machine that wants to execute a variable display game in which the maximum fluctuation time exceeds 100 seconds.

  FIG. 23 shows an example of progress of the variable display game, and the relationship between the maximum fluctuation time of the variable display game and the synchronization interval of the update timing of the random number and the emission timing when the above embodiment is applied. The variable display game shown in FIG. 23 (A) shows the progress of the game accompanied by the occurrence of reach, and the variable time is set long in order to execute the reach effect. In this embodiment, as shown in FIG. 23B, the frequency of the crystal oscillator is set so that the synchronization interval TL between updating and firing random numbers is longer than the maximum variation time X of the variation display game. Is selected.

FIG. 24 shows an example of distribution of the variable display game. In this embodiment, when the fluctuation time of the fluctuation display game is to be extended, the fluctuation time is divided into the first half fluctuation and the second half fluctuation, and each fluctuation time is set. Moreover, the fluctuation time in time saving mode and the fluctuation time in the case of performing pre-reading effect are also set, respectively. Furthermore, in the case of time saving, the fluctuation time is set to be different values such as “3.8 s” and “12.8 s” depending on whether the number of reservations (number of starting memories) is large or small.
As shown in FIG. 24, when the result is out, the normal fluctuation game without reach is considered to be only the first half fluctuation. The fluctuation display game with the largest fluctuation time is a special reach that is a big hit of 15 rounds, this fluctuation is the fluctuation time of the first half fluctuation time 35s (seconds), the fluctuation time of the second half fluctuation is 30s, the total fluctuation of 65s . In the present invention, the fluctuation time of the fluctuation display game means the total fluctuation time unless specifically limited.

  In the above specific setting example, the update period of the random number is first determined, and the synchronization interval between the update of the random number and the emission is longer than the maximum fluctuation time of the variable display game with respect to the determined random number update period. The frequency of the quartz oscillator is determined as described above, but on the contrary, the frequency (emission period) of the quartz oscillator is first determined, and updating and emission of random numbers are performed for the determined frequency. The random number update period may be determined such that the synchronization interval of the second symbol is longer than the maximum variation time of the variation display game.

Next, how to optimally obtain the value of m and the value of M, which are variables of the above-mentioned expression “random number size / frequency = m / M” defined as the update cycle of the big hit random number will be described.
First, for the value of m, an integer including “2” as a prime factor, preferably a number represented by a power of 2 (for example, 2 ⁹ as shown in FIG. 19), more preferably m = 2 ⁿ Let n be a multiple of 4 (a so-called multiple of bytes).
As described above, when the number represented by the power of 2 is set as the m value, a means (circuit) for defining the range of random numbers to be counted is provided in the random number generation circuit configured with a binary counter circuit or the like. Since a random number having a desired size can be generated, the size of the random number generation circuit can be reduced. When ⁿ is expressed as m = 2 ⁿ and m is a multiple of 4, the data size of the CPU (microcomputer) used in the normal game control device is an integral multiple of bytes Therefore, processing such as generation of random numbers, transfer of random number data, and processing by the CPU is extremely easy, and development of a program becomes easy.

Next, the value of M is an integer including “5” as a prime factor, preferably a number represented by a power of 5 (for example, 5 ⁷ as shown in FIG. 19). m can be easily selected by selecting an integer including "2" or a number represented by a power of 2 as a value of m, and selecting an integer including "5" or a number represented by a power of 5 as a value of M. And M can be integers that are disjoint. Also, relatively many commercially available CPUs having an operating frequency of 10 such as 10 MHz, 100 MHz and 1 GHz are provided, and such an operating frequency can be expressed by 10 ⁿ , 10 ^{Since n} can be transformed into 2 ⁿ × 5 ⁿ , it is apparent that it is expressed by a power of 5, and a system satisfying the above conditions can be easily configured.

From the above description, the present application
Random number generation means for cyclically updating a counter value with a predetermined number as an update range;
Launching means for launching a game ball into the game area of the game board;
Game control means for controlling the game in an integrated manner;
A gaming machine that generates a special gaming state advantageous to a player when an execution result of a variable display game in which a plurality of identification information is variably displayed in accordance with establishment of a start condition is a predetermined special result.
The game control means
The random number generation means acquires the counter value to be updated at any timing, and uses the acquired counter value as a random number for game control.
The launching means is
An oscillation means for generating an oscillation signal of a predetermined oscillation frequency;
Determine the firing cycle of the game ball in accordance with the oscillation frequency,
Firing the gaming ball in a firing cycle based on the oscillation frequency,
It can be seen that the synchronization interval between the firing period and the update period of the counter value by the random number generation means is set to be longer than the maximum fluctuation time of the fluctuation display game.

Here, "synchronization interval" is synonymous with the synchronization period. The “maximum fluctuation time of the fluctuation display game” means the fluctuation time of the fluctuation display game of the maximum fluctuation time when there are a plurality of types of fluctuation display games having different fluctuation times. The "variation display game" includes both the special view fluctuation display game and the common view fluctuation display game in the embodiment. "Oscillator means" means an oscillator (also referred to as a vibrator) such as, for example, a crystal oscillator or a ceramic oscillator, or one including an oscillator and its drive circuit.
Then, according to the invention as described above, since the fluctuation time of the fluctuation display game is determined for each effect, when there is a player who recognizes the synchronization interval, the synchronization interval is known based on that time. Therefore, there is a possibility that a specific random number based on the fluctuation of a specific variable display game may be shot, but as in the above configuration, the firing cycle and the update cycle of the counter value (random number update cycle) updated by the random number generating means By making the synchronization interval longer than the maximum time of the variable display game, it is possible to prevent the shooting of a predetermined random value based on the fluctuation of the specific variable display game, and to ensure the fairness of the game.

Also, the firing period of the firing unit as the launching means is determined according to the oscillation frequency specific to the oscillating means decided to be used, and the synchronization interval between the determined firing period and the random number updating period is the variable display game Because it is set to be longer than the maximum fluctuation time of, the burden on the designer is lightened as compared with the method of simultaneously determining both the firing period and the random number update period.
Furthermore, since the setting of the update range of the counter value of the random number generation means can be performed by software, even if it is desired to change the fluctuation time of the variable display game, setting change capable of preventing shooting of random values simply by rewriting the program. It can be done easily.

Also, in the present application,

And a divider circuit for adjusting the oscillation frequency according to a predetermined division ratio.
The emission period is determined according to the number of pulses, the oscillation frequency, and the division ratio.
The size of the random number updated by the random number generation means is a value that is an integer multiple of m, the update frequency of the random number is a value that is an integer multiple of M, and a multiple is set so that the update cycle of the random number can be represented by m / M. When the m value constituting the numerator of the m / M and the M value constituting the denominator are integers which are relatively prime to each other,
The emission period obtained by dividing the product of the number of drive pulses required for one emission by the drive source and the division ratio by the divider circuit by the oscillation frequency of the oscillation means is represented by n / N. The n value constituting the numerator of n / N and the N value constituting the denominator are integers which are relatively prime to each other,
The product value mn of the m value and the n value is divided by the greatest common divisor Gcd (Nm, Mn) of the product value Nm of the N value and the m value and the product value Mn of the M value and the n value The value D is longer than the maximum fluctuation time of the fluctuation display game,
An invention is included in which the synchronization interval between the firing period and the update period of the random number is set to be longer than the maximum fluctuation time of the variable display game and shorter than the value D.

Here, the "drive source" includes a solenoid as well as the pulse motor, and "unit operation" means one rotation in the case of the pulse motor and one reciprocation in the case of the solenoid.
According to the invention, the frequency divider circuit for adjusting the oscillation frequency is provided, and the firing period is the number of drive pulses of the drive source for driving the ball firing rod and the oscillation frequency of the oscillation means and the division ratio of the frequency divider circuit. Since it is decided correspondingly, it is possible to select an oscillator to be used from among crystal oscillators of a plurality of types of commercially available oscillation frequencies, so that it is possible to avoid a cost increase and to set a firing cycle appropriately. It is possible to easily prevent the shooting of a predetermined random value based on the variation of the display game.
In addition, the synchronization interval of the firing cycle and the update cycle of the random number can be made longer than the maximum time of the variable display game without extremely increasing the range of the random numbers generated by the random number generation means. It can be reduced.

Furthermore, the present application includes the invention in which the m value is a value including “2” as a prime factor, and the M value is a value including “5” as a prime factor.
According to this invention, the m value of the numerator in the equation of “random number size / frequency = m / M” giving the update cycle of the random number is a value including “2” as a prime factor, and the random number generation means is generally When configured as a binary counter circuit or the like, the size of the random number generation circuit can be reduced. In addition, the M value of the denominator in the formula "size of random number / frequency = m / M" is a value including "5" as a prime factor, so that the operating frequency is 10 when the game control means is configured by the CPU Since a CPU that is an exponentiation, that is, an exponentiation of 5, can be easily obtained, a system that satisfies the desired conditions can be easily configured.

Further, the present application includes the invention in which the greatest common divisor of the m value and the n value includes “2” or “a power of 2”.
According to this invention, when the greatest common divisor of m and n values includes “2” or “a power of 2”, the product value mN of m values and N values, M values and n values Since the greatest common divisor Gcd (Nm, Mn) of the product value Mn with a value also includes “2” or “a power of 2”, the product value mn of the m value and the n value is The value D divided by the greatest common divisor Gcd (Nm, Mn) of the product value Nm of the N value and the m value and the product value Mn of the M value and the n value can be made small and easy to handle In addition, when the value of the synchronization cycle is determined, the values that m / M and n / N can take are many, and the options can be expanded.

Furthermore, the present application includes the invention in which "2" and "5" are included in the greatest common divisor Gcd (Nm, Mn).
According to this invention, the greatest common divisor Gcd (Nm, Mn) of the product value mn of m and n values, the product value Nm of n and m values, and the product value Mn of M and n values The value D divided by D can be made smaller, which makes it easier to handle, and when the value of the synchronization cycle is fixed, the values that m / M and n / N can take are more It can be expanded, and it becomes easy to obtain an oscillator or CPU that satisfies the desired conditions.
