  FIG. 5 is a block diagram of the game arithmetic processing device 600 according to the embodiment of the present invention.

  The game processing unit 600 is manufactured as an IC for a so-called amuse chip, and is divided into a game area unit 600A for performing game control and an information area unit 600B for managing information.

  First, the game area unit 600A includes a CPU core 601, a user program ROM 602, an HW parameter ROM 603 (generally referred to as ROM), a user work RAM 604 and a mirrored RAM 605 (collectively referred to as RAM), an external bus interface (I / F) 606, The bus switching circuit 607, random number generation circuit 608, clock generator 609, reset / interrupt control circuit 610, address decoder 611, output control circuit 612, boot block 613, decryption / ROM writing circuit 614, and bus 615. The

  The CPU core 601 performs arithmetic processing for game control. The user program ROM 602 stores a control program. The control program is a game control program for controlling a game when the game arithmetic processing device 600 is the game microcomputer 101 provided in the game control device 100, and the game arithmetic processing device 600 is a payout control device. In the case of the game microcomputer 211 provided in 210, a payout control program for paying out game balls.

  The HW parameter ROM 603 stores validity confirmation information. The legitimacy confirmation information is information in the case of performing a simple check of legitimacy of the gaming arithmetic processing device 600. For example, a unique ID indicating a unique identifier of the pachinko gaming machine 1 and a manufacturer code (pachinko gaming machine 1 A unique identifier assigned to each manufacturer), a rank code indicating the rank (1 type, 2 type, etc.) of the pachinko gaming machine 1, and a model code set by the manufacturer for the type of the pachinko gaming machine 1 The inspection code indicating the inspection number, the RAM backup code indicating whether or not the RAM is backed up when the power is turned on, the tax rate set by the tax rate setting switch 226, the lending fee set by the lending fee setting switch 227, and the like. Further, the HW parameter ROM 603 stores only one unique ID that is a unique identifier of the inspection apparatus that first transmitted the lending information request.

  When the third party organization or the manufacturer of the pachinko gaming machine 1 writes the program in the user program ROM 602, the validity confirmation information is written in the HW parameter ROM 603.

  When performing a simple check of the gaming arithmetic processing device 600, when the gaming arithmetic processing device 600 is powered on, the arithmetic value calculated by the gaming arithmetic processing device 600 itself and the validity confirmation information (ie, third party engine etc.) And a result value set in advance by the above-described (3), the game processing unit 600 can be easily checked.

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

  The external bus interface 606 has interfaces such as a memory request signal MREQ, an input / output request signal IORQ, a memory write signal WR, a memory read signal RD, and a mode signal MODE, and the bus switching circuit 607 is a 16-bit interface. The interface is used for address signals A0 to A15 and 8-bit data signals D0 to D7.

  For example, if the data signals D0 to D7 are added while sequentially increasing the address signals A0 to A15 while the MODE signal is set to [H] level, the writing mode to the user program ROM 602 is set and the pachinko gaming machine 1 The program can be written by the manufacturer or a third party. Note that the write mode allows a program to be written, and does not allow a boot program stored in the boot block 613 to be written. Further, when the writing of the program to the user program ROM 602 is completed, a writing end code is recorded in a predetermined area of the HW parameter ROM 603 (for example, recorded by physically cutting a predetermined code or a predetermined bit). Thus, when a write end code is recorded in the HW parameter ROM 603, a new program cannot be written in the user program ROM 602.

  The random number generation circuit 608 generates a random number related to whether or not to add a game value (for example, jackpot) in the game execution process (random numbers are used to determine jackpots or symbols when stopped). A mathematical method (for example, a congruent method or an M-sequence method) for generating a uniform random number is used. Note that when the gaming arithmetic processing device 600 is the gaming microcomputer 211 provided in the payout control device 210, the random number generation circuit 608 may not be provided.

  The clock generator 609 generates a predetermined clock signal and further divides the generated clock signal to generate a signal related to timing necessary for game control (details will be described later in FIG. 6). A reset / interrupt control circuit (interrupt signal generation means) 610 detects a reset interrupt signal RST from an interrupt signal generation circuit (not shown) and notifies the CPU core 601 of it.

  The address decoder 611 decodes the location of the built-in device and the built-in control / status register group by the memory mapped I / O method and the I / O mapped I / O method.

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

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

  The bus 615 includes a data bus, an address bus, and a control bus, and extends to the information area portion 600B.

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

  The HPG program ROM 616 stores an HPG program for performing various inspection operations.

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

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

  The HPG work RAM 619 is used as a work area (work area) when executing processing based on a program in the information area unit 600B.

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

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

  Various devices constituting the game area portion 600A and the information area portion 600B are mounted on a common semiconductor substrate and packaged as one chip.

  Next, the random number generation circuit 608 will be described in detail with reference to FIG.

  FIG. 6 is a block diagram of the random number generation circuit 608 in the game arithmetic processing device 600 according to the embodiment of the present invention.

  The random number generation circuit (random number generation means) 608 includes a random number update controller 608a, a first random number block 608b, a second random number block 608c, a third random number block 608d, and a fourth random number block 608e.

  The random number update controller (update means) 608a performs arithmetic processing for generating random numbers related to whether or not to add a game value (for example, jackpot) in the game execution process, and generates a uniform random number Mathematical techniques (for example, congruence method or M-sequence method) are used. The random number update controller 608a can access a reset interrupt control circuit 610, a CTC (Counter / Timer Circuit) 609a and a frequency dividing circuit 609b that constitute the clock generator 609.

  The first random number block 608b includes a CTC update permission register (update means) 608b1, a tap setting register 608b2, a random number update trigger register (update means) 608b3, a maximum value setting register (range information storage means) 608b4, a start value setting register 608b5, It is composed of a round completion notification register 608b6, a random number counter (random number storage means) 608b7, a work area 608b8, and a random number update notification register (update information storage means) 608b9. The second random number block 608c, the third random number block 608d, and the fourth random number block 608e have the same configuration as that of the first random number block 608b, and thus the description thereof is omitted.

  The CTC update permission register 608b1 sets whether or not the update of the random number counter 608b7 is permitted / not permitted. If it is set to “permitted”, the generation of the CTC signal based on the CTC 609a is used as a trigger for the random number counter 608b7. Will be updated.

  The tap setting register 608b2 operates the random number counter 608b7 in the “counter mode” and is “0” when the power is turned on. At this time, the random number counter 608b7 does not operate. . Then, when a value other than “0” is written in the tap setting register 608b2, the random number counter 608b7 operates. In the case of the “random number mode”, the type of the M-sequence recurrence formula is determined by the written value.

  The random number update trigger register 608b3 is a register that can be directly written from the CPU core 610, and the random number counter 608b7 is updated when a specified value is written from the CPU core 610. At this time, the random number counter 608b7 is updated regardless of whether the setting of the CTC update permission register 608b1 is “permitted” / “not permitted”.

  The maximum value setting register 608b4 sets the maximum value and mode of the random number counter 608b7. The maximum value is set to a value between 8 and 4095. The mode is set to either “random number mode” or “counter mode”. When the set maximum value is N, the random number counter 608b7 is updated in the range of 1 to N in the “random number mode”, and the random number counter 608b7 is updated in the range of 0 to N in the “counter mode”.

  The start value setting register 608b5 sets the start value of the random number counter 608b7. When the random number counter 608b7 makes one round of a predetermined cycle, this start value is set in the random number counter 608b7. Specifically, for example, when a value larger than the maximum value N set in the maximum value setting register 608b4 is set as the start value S, the maximum value N when the random number counter 608b7 makes a predetermined cycle once. The remainder value obtained by dividing the value by the start value S is set in the random number counter 608b7.

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

  The random number counter 608b7 is composed of a 12th-order (12-bit) random number sequence, and until a predetermined value is written to the tap setting register 608b2, data is set and the initial value of the random number when the power is turned on can be changed. it can. Therefore, the range of the random number counter 608b7 can take a value between 1 and 4095 in the “random number mode”, and can take a value between 0 and 4095 in the “counter mode”. Become.

  The work area 608b8 functions as an update buffer for the random number counter 608b7, and holds a value immediately before the power failure at the time of a power failure. When the update of the random number is instructed by the CTC 609a or the random number update trigger register 608b3, the value of the work area 608b8 is continuously updated until the value is in the range indicated by the maximum value setting register 608b4. While the value in the work area 608b8 is being updated, “0” is set in the random number counter 608b7 regardless of whether it is in the “random number mode” or the “counter mode”. Therefore, in the “random number mode”, if “0” that does not belong to the numerical value (1 to N) within the update range is set in the random number counter 608b7, it indicates that the random number counter 608b7 is being updated.

The random number updating notification register 608b9 notifies that the random number is being updated, and is set to ON while the random number counter 608b7 is being updated by the CTC 609a or the random number update trigger register 608b3. Is set to off.
The CTC 609a generates a timer interrupt signal (CTC signal) generated at a predetermined cycle (for example, 2 milliseconds). The frequency dividing circuit 609b divides the original clock signal input from the outside of the gaming arithmetic processing device 600, generates a clock signal having a longer cycle than the original clock signal, and inputs the generated clock signal to the CTC 609a. At this time, the original clock signal is converted into a frequency-divided signal having a double cycle and input to the random number controller 608a.

  Next, the main process of the game control apparatus 100 will be described with reference to FIG.

  FIG. 7 is a flowchart of the main process in the embodiment of the present invention.

  The main process is executed by the CPU 102 of the game control device 100 when the power is turned on to the pachinko gaming machine 1 or when the power failure is restored.

  First, the game control device 100 prohibits an interrupt performed at a predetermined time period (for example, a period of 2 milliseconds) (step S1).

  Next, the game control device 100 sets each interrupt mode (step S2) and permits access to the RAM 104 (step S3).

  Then, the game control device 100 performs initial setting of peripheral devices of the CPU (step S4) and sets a stack pointer (step S5).

  Next, the game control device 100 determines whether or not the RAM clear switch 162 that is provided in the pachinko gaming machine 1 and initializes the information stored in the RAM 104 of the game control device 100 is ON (step S6). When the RAM clear switch 162 is turned on, the data stored in the RAM 104 is cleared.

  If it is determined in step S6 that the RAM clear switch 162 is ON, the game control device 100 clears the data stored in all the RAMs 104 to be used (step S11).

  And the game control apparatus 100 sets the initial value at the time of power activation in RAM104 (step S12). The initial value when the power is turned on is a predetermined value.

  On the other hand, when it is determined in step S6 that the RAM clear switch 162 is not ON, the game control apparatus 100 determines whether or not the power failure recovery information indicating that the recovery from power failure is set in the RAM 104. Thus, it is determined whether or not the power is turned on when the power failure is restored (step S7).

  If it is determined in step S7 that the power is not turned on when the power failure is restored, the process proceeds to step S11 in order to initialize the pachinko gaming machine 1.

  On the other hand, if it is determined in step S7 that the power is turned on at the time of power failure recovery, the game control device 100 checks the RAM 104 to determine whether the data stored in the RAM 104 is corrupted. Sum is calculated (step S8), and it is determined whether or not the checksum is normal (step S9). Specifically, when there is a power failure, the game control apparatus 100 determines whether or not the checksum of the data stored in the RAM 104 matches the checksum of the data currently stored in the RAM 104.

  If it is determined in step S9 that the checksum is abnormal, the data stored in the RAM 104 is broken, and the data stored in the RAM 104 when a power failure occurs cannot be taken over. In order to initialize the gaming machine 1, the process proceeds to step S11, and a power-on process is executed.

  On the other hand, if it is determined in step S9 that the checksum is normal, the data stored in the RAM 104 is normal and the power failure recovery process can be executed, so the initial value at the time of power failure recovery is set in the RAM 104. (Step S10).

  Next, the game control device 100 sets the CTC 609a which is a timer for measuring time (step S13), and permits the interrupt prohibited in the process of step S1 (step S14).

  Next, the game control device 100 acquires the contents of a power failure inspection region that is a specific region of the RAM 104 and stores a power failure flag indicating that a power failure has occurred (step S15). The power failure flag is set when it is determined whether or not the voltage supplied to the pachinko gaming machine 1 is equal to or lower than a predetermined value.

And game control device 100 judges whether a power failure flag is stored, and judges whether a power failure has occurred (Step S16).

  If it is determined in step S16 that no power failure has occurred, the game control device 100 returns to step S15.

  On the other hand, when it is determined in step S16 that a power failure has occurred, the game control device 100 executes the power failure process of steps S17 to S21.

  First, the game control device 100 sets an interrupt prohibition (step S17), and sets all output ports to OFF (step S18).

  The game control apparatus 100 stores the power failure recovery information in the RAM 104 (step S19), calculates the checksum of the data stored in the RAM 104 before the RAM 104 is turned off, and stores the calculated checksum value. (Step S20).

  Then, the game control device 100 prohibits access to the RAM 104 (step S21), and waits until the pachinko gaming machine 1 is turned off. In addition, since the backup power supply is connected to the game control apparatus 100, even if a power failure occurs, the power supply is not immediately turned off.

  Next, timer interrupt processing executed by the game control apparatus 100 will be described with reference to FIG. The timer interrupt process is executed by interrupting the main process (FIG. 7) when the CTC 609a generates a CTC signal.

  FIG. 8 is a flowchart of timer interrupt processing in the embodiment of the present invention.

  In this timer interrupt process, first, a process of saving register data (step a) is performed. Next, an input process (step b) is performed for processing inputs from various sensors (special drawing start SW 34A, general diagram start SW 31A, etc.). Then, based on the output data set in the various processes, an output process (step c) for performing drive control of an actuator such as a solenoid (large winning opening SOL38, ordinary electric power SOL90) is performed.

  Next, a jackpot random number for determining the hit-off of the special figure fluctuation display game, a jackpot symbol random number for judging the jackpot symbol of the special figure fluctuation-display game, a hit for judging the hit-off of the normal figure fluctuation display game Random number update and winning port switch monitoring processing for updating random numbers and monitoring whether or not signals are input from the count SW 36A, winning port SW 32a,... 32n (whether or not a signal indicating detection of a game ball is input). (Step d) is performed (details will be described later with reference to FIG. 11). Then, an error monitoring process (step e) for monitoring each signal and error is performed, and a special figure / general figure game process (step f) for performing a process related to the special figure fluctuation display game and the normal figure fluctuation display game is performed.

  Next, a segment LED editing process (step g) that is provided in the pachinko gaming machine 1 and displays various information related to the game is performed. Then, an external information editing process (step h) is performed in which a signal to be output to the external management apparatus is set in the output buffer. Next, processing for declaring the end of interrupt (step i) is performed, processing for restoring the saved register data (step j) is performed, processing for permitting interrupt (step k) is performed, and timer interrupt processing is performed. finish.

  Next, the processing of the random number update controller 608a of the random number generation circuit 608 will be described with reference to FIGS.

  FIG. 9 is a flowchart of the first half of the random number update controller processing in the embodiment of the present invention. FIG. 10 is a flowchart of the latter half of the random number update controller processing in the embodiment of the present invention.

  First, the random number update controller 608a initializes values stored in other storage areas and registers, excluding values stored in the work area 608b8, based on a reset interrupt signal from the reset interrupt control circuit 610. (Step S101). At this time, the value of the circulation counter is set to “0”.

  Next, the value of the random number counter stored in the work area 608b8 is taken into the random number counter 608b7 (step S102).

  Next, the change of the random number counter 608b7 is permitted (step S103), and the setting of the tap setting register 608b2 is awaited (step S104).

  Next, change of the random number counter 608b7 is prohibited (step S105), the value of the random number counter 608b7 at this time is stored in the work area 608b8 (step S106), and the number counter is set to “0” (step S107). Until the change of the random number counter 608b7 is prohibited, an arbitrary value can be written to the random number counter 608b7 by the CPU core 601 (FIG. 5).

  Next, it is determined whether or not a CTC signal is generated by the CTC 609a (step S108).

  In the determination of whether or not the CTC signal is generated by the CTC 609a (step S108), if the CTC signal is generated by the CTC 609a (step S108; Yes), whether or not the CTC use mode is set, specifically, the CTC update permission. It is determined whether or not the register 608b1 is set to “permitted” (step S109).

  If it is determined in this CTC use mode (step S109) that the CTC use mode is set (step S109; Yes), the process proceeds to step S111. On the other hand, if it is determined in this CTC use mode (step S109) that the CTC use mode is not set, that is, if the CTC update permission register 608b1 is set to “impossible” (step S109; No), the random number is updated. It is determined whether or not a specified value is written in the trigger register 608b3 (step S110).

  In the determination of whether or not the CTC signal is generated by the CTC 609a (step S108), if the CTC signal is not generated by the CTC 609a (step S108; No), the specified value is written in the random number update trigger register 608b3. Whether or not there is is determined (step S110).

  In the determination of whether or not the specified value is written in the random number update trigger register 608b3 (step S110), if the specified value is written in the random number update trigger register 608b3 (step S110; Yes), the process proceeds to step S111. . On the other hand, in the determination of whether or not the specified value is written in the random number update trigger register 608b3 (step S110), if the specified value is not written in the random number update trigger register 608b3 (step S110; No), step S108 Return to.

  Next, the random number updating notification register 608b9 is set to ON (step S111), the value of the random number counter 608b7 is set to “0” (step S112), and a frequency dividing signal from the frequency dividing circuit 609b is waited (step S112). Step S113).

  Next, it is determined whether the mode set in the maximum value setting register 608b4 is the “random number mode” or the “counter mode” (step S114).

  In determining whether the mode set in the maximum value setting register 608b4 is the “random number mode” or the “counter mode” (step S114), the mode set in the maximum value setting register 608b4 is “counter mode”. In this case, it is determined whether or not the value of the work area 608b8 is larger than “0” (step S115).

  In the determination of whether or not the value of the work area 608b8 is larger than “0” (step S115), when the value of the work area 608b8 is “0” (step S115; No), the value of the work area 608b8 is maximized. A value is set (step S116). On the other hand, if the value of the work area 608b8 is greater than “0” in the determination of whether the value of the work area 608b8 is greater than “0” (step S115) (step S115; Yes), the value of the work area 608b8. Is decremented by 1 (step S117).

  Next, the value of the circulation counter is incremented by 1 (step S118), and it is determined whether or not the value of the circulation counter is greater than or equal to the maximum value of the random number counter (step S119).

  In the determination of whether or not the value of the circulation counter is equal to or larger than the value added to the maximum value of the random number counter 608b7 (step S119), the value of the circulation counter is equal to or larger than the value added to the maximum value of the random number counter 608b7 (step S119). S119; Yes) sets the value of the circulation counter to “0” (step S120). On the other hand, in the determination of whether or not the value of the circulation counter is equal to or larger than the value added to the maximum value of the random number counter 608b7 (step S119), the value of the circulation counter is not equal to or larger than the value added to the maximum value of the random number counter 608b7. In step S119; No, the process proceeds to step S134.

  Next, the start value setting register 608b5 acquires the start value and corrects it to be equal to or less than the maximum value (step S121). Specifically, at this time, since the acquired start value is larger than the maximum value, correction is performed using the remainder value when the maximum value is divided by the start value as the start value.

  Then, the start value is taken into the work area 608b8 (step S122), and the one-round completion notification register 608b6 is set to ON (step S123).

Next, it is determined whether or not the value of the number counter has reached a specified value (step S134). Here, the specified value (specified update time) is, for example, the specified value is “2” in the “counter mode”, the specified value is in the “random number mode”, and the maximum value is “17” or more. In the case of “20” and “random number mode” and the maximum value is “16” or less, the specified value is set to “200”. Data of these specified values (specified update time) is stored in the ROM 103 of the game microcomputer 101 provided in the game control device 100.
In this case, when the update of the random number counter 608b7 is started, the update of the random number counter 608b7 is not completed until the frequency division signal input from the frequency dividing circuit 609b to the random number update controller 608a is detected a predetermined number of times. The number of detections is also fixed to a certain number. In other words, in the “counter mode”, in order to update the random number counter 608b7, it takes time to generate the divided signal twice (specified update time). In the case of the “random number mode”, when the maximum value of the random number counter is “17” or more, it takes time to generate the divided signal 20 times in order to update the random number counter 608b7. In the case of the “random number mode”, when the maximum value of the random number counter is “16” or less, it takes time to generate the divided signal 200 times in order to update the random number counter 608b7.
Thereby, a plurality of prescribed update time storage means for storing a plurality of associated maximum update values and prescribed update times for updating random number values, and a plurality of prescribed update times stored in the prescribed update time storage means. Based on the maximum value of the range information, the selection means for selecting and specifying one of the specified update times, and the time required for updating the random number value by the update means is set to the specified update time selected and specified by the selection means Setting means. In addition, the specified update time is configured such that the specified update time is gradually increased when the maximum value is small compared to the maximum value having a large maximum value.

  In the determination as to whether or not the value of the number counter has reached the specified value (step S134), if the value of the number counter has not reached the specified value (step S134; No), a frequency division signal is waited (step s137). ), The value of the number counter is incremented by 1 (step S138), and the process returns to step S134. On the other hand, if it is determined whether or not the value of the number counter reaches the specified value (step S134), if the value of the number counter reaches the specified value (step S134; Yes), the value is taken into the work area 608b8. The value is set in the random number counter 608b7 (step S135), the random number updating notification register 608b9 is set off (step S136), and the process returns to step S107.

  Further, in determining whether the mode set in the maximum value setting register 608b4 is the “random number mode” or the “counter mode” (step S114), the mode set in the maximum value setting register 608b4 is the “random number mode”. In this case, the process proceeds to step S124.

  Then, the M-sequence random number is updated in the work area 608b8 (step S124), and it is determined whether or not the value based on the M-sequence random number in the work area 608b8 is larger than the maximum value (step S125).

  In determining whether the value based on the M-sequence random number in the work area 608b8 is larger than the maximum value (step S125), if the value based on the M-sequence random number in the work area 608b8 is larger than the maximum value (step S125; Yes) ) Determines whether or not a frequency-divided signal has been detected (step S126).

  In the determination of whether or not the frequency-divided signal is detected (step S126), when the frequency-divided signal is detected (step S126; Yes), the value of the number counter is incremented by 1 (step S127), and step S124 is performed. Return to. On the other hand, in the determination of whether or not the frequency-divided signal has been detected (step S126), when the frequency-divided signal has not been detected (step S126; No), the process returns to step S124.

  Also, in the determination of whether or not the value based on the M-sequence random number in the work area 608b8 is larger than the maximum value (step S125), the value based on the M-sequence random number in the work area 608b8 is not larger than the maximum value (step S125). No) increments the value of the circulation counter by 1 (step S128), and determines whether or not the value of the circulation counter is equal to or greater than the maximum value (step S129).

  In the determination of whether or not the value of the circulation counter is greater than or equal to the maximum value (step S129), if the value of the circulation counter is greater than or equal to the maximum value (step S129; Yes), the value of the circulation counter is set to “0” (step S129). Step S130). On the other hand, if it is determined whether or not the value of the lap counter is equal to or greater than the maximum value (step S129), if the value of the lap counter is not equal to or greater than the maximum value (step S129; No), the process proceeds to step S134.

  Next, the start value setting register 608b5 acquires the start value and corrects it to be equal to or less than the maximum value (step S131). Specifically, at this time, since the acquired start value is larger than the maximum value, correction is performed using the remainder value when the maximum value is divided by the start value as the start value.

  Then, the start value is taken into the work area 608b8 (step S132), the one-round completion notification register 608b6 is set to ON (step S133), and the process proceeds to step S134.

  Next, the random number update and the winning opening SW monitoring process in the timer interrupt process will be described with reference to FIG. In this figure, it is assumed that the CTC update permission register 608b1 is set to “impossible”, and the value of the random number counter 608b7 is not updated when the CTC signal is generated.

  FIG. 11 is a flowchart of random number update and winning opening SW monitoring processing in the embodiment of the present invention.

  First, an effect-related random number used for effects in the variable display game is updated (step d1).

  Next, it is determined whether or not the game ball has won the general winning opening 32, the normal symbol starting gate 31, the starting winning opening 34, or the special variable winning apparatus 36 (step d2).

  In determining whether or not a game ball has won the general winning opening 32, the normal symbol starting gate 31, the starting winning port 34, or the special variable winning device 36 (step d2), the general winning port 32, the normal symbol starting gate 31 are used. When a game ball is won in the start winning opening 34 or the special variable winning device 36 (step d2; Yes), preparation for a prize ball command is performed (step d3). On the other hand, in the determination of whether or not a game ball has won the general winning opening 32, the normal symbol starting gate 31, the starting winning opening 34, or the special variable winning device 36 (step d2), the general winning opening 32, the normal symbol starting. If the game ball has not won any of the gate 31, the start winning opening 34, or the special variable winning device 36 (step d2; No), the process proceeds to step d11.

  Next, it is determined whether or not the winning detected at step d2 is a winning at the start winning opening 34 (step d4).

  If the winning detected at step d2 is a winning at the start winning opening 34 (step d4; Yes), whether or not the number of reserved memories of the variable display game (special figure variable display game) based on the winning is less than four. A determination is made (step d5). On the other hand, when the winning detected at step d2 is not a winning at the start winning opening 34 (step d4; No), the process proceeds to step d10.

  Next, in the determination (step d5) of whether or not the number of reserved memories of the variable display game based on the prize (special figure variable display game) is less than 4, the number of reserved memories of the variable display game based on the prize is less than 4. In the case (step d5; Yes), the pending storage number is incremented by 1 (step d6), and the random number updating notification register 608b9 is referred to (step d7). On the other hand, when it is determined whether or not the number of reserved storages of the variable display game based on the winning is less than 4 (step d5), the number of reserved storages of the variable display game based on the winning is not less than 4 (step d5; No). The process proceeds to step d10.

  Next, it is determined whether or not the random number updating notification register 608b9 referred to in step d7 is set to ON, that is, whether or not the random number counter 608b7 is being updated (step d8).

In the determination of whether or not the random number counter 608b7 is being updated (step d8), if the random number counter 608b7 is being updated (step d8; Yes), the process returns to step d7. On the other hand, if the random number counter 608b7 is not updated (step d8; No) in the determination of whether or not the random number counter 608b7 is being updated (step d8), the random number value (the value of the random number counter 608b7) at this time is used. Store (step d9).
Thereby, the random number updating notification register 608b9 provided separately from the random number counter 608b7 indicates that the random number counter 608b7 is being updated regardless of whether it is the “random number mode” or the “counter mode”. It will function as updating information.

Next, a random value is set in the start value setting register 608b5 (step d10), the specified value is written in the random number update trigger register 608b3 (step d11), and this process is terminated. And the update of the value of the random number counter 608b7 is started by writing the specified value into the random number update trigger register 608b3 (see step S110 in FIG. 9). As a result, the random number counter 608b7 can be updated by using the margin time until the next CTC signal generation.
The processing from step d4 to d11 is performed by updating the reserved memory number of the special figure variable display game when the winning detected at step d2 is winning at the start winning opening 34, and updating the random number updating notification register. It is determined whether or not 608b9 is on and the process of storing the value of the random number counter 608b7 is performed. Even if the winning detected in step d2 is a winning to the normal symbol start gate 31, The same processing may be performed by updating the number of reserved memories of the usual variable display game.
In this case, since each register belonging to the first random number block 608b (FIG. 6) is used exclusively for the special figure variation display game, each register belonging to the second random number block 608c is dedicated to the common figure variation display game. It is set in advance to use. Then, when the normal symbol starting gate 31 is won (passed), the number of reserved memories of the normal symbol display game is updated, and whether or not the random number updating notification register (not shown) of the second random number block 608c is on. And a process of storing the value of the random number counter (not shown) of the second random number block 608c may be performed.
Thereby, the game control device (game control means) 100 has an acquisition condition detection means for detecting that a predetermined random number acquisition condition (such as winning at the start winning opening 34 or winning at the normal symbol starting gate 31) has occurred. When the generation condition detection unit detects the occurrence of a predetermined random number acquisition condition, the acquisition condition detection unit includes a random value acquisition unit that acquires a random value from the random value storage unit.
In step d8, it is determined whether or not the random number updating notification register 608b9 is set to ON, and it is determined whether or not the random number counter 608b7 is being updated. Even without reference, it is also possible to determine whether or not the update is in progress only with the value of the random number counter 608b7. In the case of the “random number mode”, if the random number counter 608b7 is set to “0” that does not belong to the numerical value (1 to N) within the update range, it indicates that the random number counter 608b7 is being updated. It is.
In this case, in the process of step d7 in FIG. 11, instead of referring to the value of the random number updating notification register 608b9, a process of referring to the value of the random number counter 608b7 is performed. Next, in step d8, it is determined whether or not the value of the random number counter 608b7 is “0”. If “0”, the process returns to step d7 to repeat acquisition of the value of the random number counter 608b7. If not, the process proceeds to step d9 to store the acquired value of the random number counter 608b7.
At this time, although limited to the “random number mode”, the random number counter 608b7 itself functions as updating information indicating that updating is in progress. In other words, the updating information is composed of random number values, and if the random number value is outside the update range, it indicates that the random value is being updated, while if it is within the update range, the random value is updated. It shows that it is not in.

  Thereby, the game control device (game control means) 100 executes a timer interrupt process in response to the generation of the interrupt signal while performing a looping process in the main process executed by the game program. During the processing, the random value is acquired by the random value acquisition means, and after the random value is acquired, a predetermined update command for updating the random value is generated by the update means. The random value acquisition means stores the random value when the acquisition condition detection means detects the occurrence of a predetermined random number acquisition condition and indicates that the random value is not being updated with reference to the updating information. A random value is acquired from the means. In addition, the random value acquisition means, when the random value acquired from the random value storage means is a numerical value outside the update range, until the random value acquired is within the update range, the random value from the random value storage means Will be repeated.

  The flowchart of the random number update and winning opening SW monitoring process described above is for the case where the CTC update permission register 608b1 is set to “impossible”. On the other hand, when it is desired to set the CTC update permission register 608b1 to “permitted”, that is, when it is desired to automatically update the value of the random number counter 608b7 when the CTC signal is generated, the processing of the step d11 (random number update trigger register 608b3) is performed. The process of writing the specified value to) is omitted.

From the above, the pachinko gaming machine 1 according to the present embodiment updates the random number value with reference to the updating information when the random number acquisition unit detects the occurrence of the predetermined random number acquisition condition by the acquisition condition detection unit. Random value is obtained from the random value storage means when it is indicated that it is not in the middle, so even if the update time of the random value changes depending on the size of the update range of the random value, refer to the information being updated and the random value It is possible to determine whether or not to acquire a random number value depending on whether or not the value is being updated, and to acquire the random value efficiently.
Further, when creating a game program, it is not necessary to consider the change in the update time of the random number value according to the size of the update range of the random value, and the game program can be developed more efficiently.

  In-update information is composed of random number values. If the random number value is outside the update range, it indicates that the random value is being updated. If it is within the update range, the random value is being updated. Therefore, it is possible to determine whether the information being updated indicates that the random number value is being updated based on the acquired random value, and it is necessary to store the information being updated in addition to the random value. The storage area can be saved.

  In addition, by the prescribed update time storage means, a plurality of candidate prescribed update times are stored in advance by associating the update time for updating the random number value with the maximum value of the update range, and selected and designated based on the maximum value Since the specified update time can be set as the time required for updating the random number value, the time required for updating the random value can be easily estimated, and the game program can be developed more efficiently.

  In addition, during the timer interruption process, the random number value is acquired by the random number value acquisition unit, and after the random number value is acquired, a predetermined update command for updating the random number value is generated by the update unit. Since there is a time lapse between the occurrence of this and the acquisition of the next random value, the processing efficiency can be improved by executing various other processes during that time.

  The gaming machine of the present invention should be considered that the embodiment disclosed this time is illustrative and not restrictive in all respects. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

For example, regarding the configuration in which the specified update time is configured so that the specified update time is gradually increased when the maximum value is smaller than the maximum value, the following may be set as follows. The specified value of the number counter in step S134 in FIG. 10 is for the “random number mode”, and when the maximum value is “8” to “100”, it is for the specified value “120” and “random number mode”. When the maximum value is “101” to “1000”, the specified value is “80”. When the maximum value is “1001” to “4095”, the specified value is “40”. Three update times may be set in stages. Thus, by setting in stages, the time required for updating the random number counter is clarified, and the program design is easy.
Further, the frequency dividing circuit 609b in FIG. 6 outputs the frequency-divided signal obtained by doubling the period of the original clock signal to the random number update controller 608a, but passes the original clock signal to the random number update controller 608a as it is, 608a may accept the original clock signal and perform comparison with the specified value in the determination processing in step S134 of FIG.
