  FIG. 5 is a block diagram showing a more specific configuration of the game microcomputer (game arithmetic processing device) 110 constituting the game control device 100, and FIG. 6 is a block diagram showing a specific configuration of the random number generation circuit. It is. A conventional gaming microcomputer has a random number generation circuit configured and connected as an external circuit, whereas the gaming microcomputer of this embodiment has a significant feature in that it includes a random number generation circuit. is there.

  The gaming microcomputer 110 of this embodiment is divided into a game control block 110A for performing game control and a management block 110B for managing information. One element constituting each circuit block described below is provided on a semiconductor substrate. It is formed as a semiconductor integrated circuit (amusement chip).

  The game control block 110A includes a CPU core 111, a program ROM 112, a work RAM 113, an external bus interface 114, a bus switching circuit 115, a decryption / ROM writing circuit 116, a mirrored RAM 117, an interrupt controller 118 as an interrupt control circuit, and a boot block 119. , A reset interrupt control circuit 120, an address decoder 121, an output control circuit 122, a clock generator 123, a random number generation circuit 124, and a HW parameter ROM 125. These functional blocks and the management block 110B are connected by a CPU bus 126.

  The CPU core 111 includes various register groups, an arithmetic / logic unit (ALU), an instruction register (IR), a decoder, a program counter (PC), a stack pointer (SP), a data bus connecting them, an address bus, and various control units. In the core, for example, configured with Z80 architecture. The CPU core 111 implements various functions necessary for controlling the gaming machine 10 by software by loading and executing the game control program stored in the program ROM 112.

  The work RAM 113 corresponds to the main memory of the CPU core 111, and is composed of a high-speed semiconductor device such as an S-RAM, for example. The work RAM 113 is used as a work area (work area) when executing processing based on the game program in the game block 110A. The work RAM 113 can be provided with a battery backup function using a dedicated terminal assigned to one of the terminal groups of the gaming microcomputer 110, and the stored contents even after the gaming machine 10 is turned off. Hold. In addition, the work RAM 113 is controlled so that the chip enable is prohibited and permitted by a protection circuit (not shown), and is read and written while the chip enable is prohibited (when power is not supplied to the gaming machine 10). None of this can be done.

  The external bus interface 114 is a circuit for performing input / output control of various signals such as a memory request signal, an input / output request signal, a memory write signal, a memory read signal, and a mode signal with an external device. The bus switching circuit 115 is a circuit that performs bus switching to enable input / output of address signals and data signals between an external bus (not shown) and the CPU bus 126 in the chip. For example, when the memory write signal WR is activated while the memory request signal MREQ or the input / output request signal IORQ is activated, an external data signal can be written to a predetermined external I / O, and the memory read signal RD is activated. Then, an external data signal can be taken in from a predetermined external I / O.

  The decryption / ROM writing circuit 116 decrypts data sent after being encrypted, generates a voltage necessary for writing to the electrically programmable program ROM 112 and the HW parameter ROM 125, and controls timing. Circuit. For example, when an external data signal is given from the outside while sequentially incrementing the external address signal while the mode signal MODE is active, it becomes a writing mode to the program ROM 112 and is made by a game machine manufacturer or a third party organization. A game program can be written. However, if the write end code is recorded in a predetermined area of the HW parameter ROM 125 described later after the game program has been written to the program ROM 112, the game program cannot be written to the program ROM 112 thereafter.

  The mirrored RAM 117 stores information obtained by copying information stored in the user work area when the clock falls (if the CPU core is Z80, processing is executed when the clock rises, and thus the mirrored RAM 117 can move in synchronization. Not so).

  The interrupt control circuit 118 is a circuit that makes an interrupt request to the CPU core 111 in response to an interrupt request signal from the outside, and sends a control signal to a circuit (for example, a random number generation circuit) inside the chip. is there. The reset interrupt control circuit 120 resets the CPU core 111 in response to a reset signal input from the outside, and generates a signal for setting various resources inside the gaming microcomputer 110 to an initial state. Circuit.

  The boot block 119 includes a ROM for storing a boot program. When the system of the gaming microcomputer 110 is reset, the boot program starts up and performs a predetermined simple check. If the boot ROM is normal, the protection setting process is executed, and then the process is transferred to a predetermined address of the game program (a predetermined address in the address space of the CPU 111 (generally, the first address 0000h in the address space)).

  The address decoder 121 decodes the address information of the CPU bus 126 and controls the output control circuit 122 according to the decoding result. The clock generator 123 generates an operation clock and a counter clock to be supplied to each block in the gaming microcomputer 110 including the CPU core 111 based on the system clock MCLK and the random number clock EXCLK supplied from the outside. .

  The random number generation circuit 124 is a circuit for generating a random number used for determination of a big hit. The conventional gaming microcomputer has a built-in one that is configured as an external circuit and adds a specific function. It is a thing. The random number generation circuit 124 will be described in detail later with reference to FIG. The HW parameter ROM 125 is used to record the write end code for prohibiting program writing to the program ROM 112 and to set parameters specific to the user system (hardware). It is constituted by a memory (for example, EPROM, EEPROM, flash memory, etc.) that can be written to.

  The management block 110B includes a management program ROM 131, a management work RAM 132, a bus monitor circuit 133, an ID property memory 134, a management control circuit 135, an external communication control circuit 136, and a local bus 137 that connects these circuit blocks. In addition, the bus monitor circuit 133 is connected to both the local bus 137 and the CPU bus 126 of the game control block 110A, so that data can be transmitted to and received from the CPU core 111 via the CPU bus 126. ing.

  The management work RAM 132 is used as a storage area for temporarily storing information of the game control block 110A read via the bus monitor circuit 133. The bus monitor circuit 133 monitors the state of the CPU bus 126. When the CPU bus 126 is not used by the CPU core 111, the program ROM 112 and the user work of the game control block 110A are connected via the CPU bus 126 as necessary. The RAM 113 and the like are accessed, and necessary data (game program, contents of the user work RAM 113, etc.) are taken into the management block 113B.

  In the ID property memory 134, a unique ID (unique information) used for identification of the gaming microcomputer 110 and determination of legitimacy is written. This unique ID is stored in the bus 137 and the external communication control circuit 136. Via a management device (hall computer) outside the gaming machine. This allows the management device to monitor the unique ID of the gaming machine. Specifically, if the unique ID set in advance in the gaming machine does not match the unique ID read by the management device, the management device disables input / output of various signals. Then, it becomes impossible to input / output signals between the various devices connected to the game control device 100 (for example, the big winning opening solenoid 58b and the normal variation winning opening solenoid 57c) and the subordinate control device and the CPU core 111. However, it becomes clear that an abnormality has occurred in the gaming machine due to the fact that the player cannot operate or the decorative lamp does not light.

  In addition to the unique ID, information such as a game type code, a rank code, a manufacturer number, a model code, and an inspection number is written in the ID property memory 134. The game type code is information for distinguishing pachinko gaming machines, throttle machines, and the like, and is represented by, for example, “P” for pachinko gaming machines and “G” for throttle machines. The rank code is a model rank code of the gaming machine 1 (a code for distinguishing between the first type and the second type), a manufacturer number, or a manufacturer ID (or manufacturer code) for identifying the manufacturer of the gaming machine 1. is there. The model code is a product code of the gaming machine 1 set by the manufacturer. The inspection number (or verification code) is a number given to the gaming machine 1 that has passed the inspection by the third party organization.

  Further, the ID property memory 134 includes a ROM and a RAM, and the contents of the ROM are copied to the RAM. That is, the unique ID, game type code, rank code, manufacturer number, model code, and inspection number are stored in the ROM, and are copied to the RAM. The copy timing is performed when the gaming machine is turned on or when the gaming microcomputer 110 is reset, for example, in an initialization process executed by the management block 110B immediately after the system reset.

  The control circuit 135 controls the operation of the management block 110B and has a buffer memory. For example, the control circuit 135 monitors the operation of the CPU core 11 via the bus monitor circuit 133, and copies the contents stored in the user work RAM 113 of the game block 110A to the mirrored RAM 117 during non-operation. Further, the contents of the ID property memory 134 of the management block 110B are transferred to the outside in response to a request from the inspection apparatus, and the program in the user program ROM 112 is sent to the outside via the bus monitor circuit 133 in response to a program request. Or transfer. The buffer memory is used for timing adjustment at the time of transfer.

  The external communication control circuit 136 communicates with an information collection terminal device and an ID inspection device provided outside the gaming machine. For example, when an information collection terminal device is connected, in response to a request from the information collection terminal device, the storage contents of the management work RAM 132 and ID property memory 134 are transferred to the requesting information collection terminal device. When the ID inspection device is connected, at least information on the unique ID stored in the ID property memory 134 is transferred to the requesting ID inspection device in response to a request from the ID inspection device.

  Next, the details of the random number generation circuit 124 built in the gaming microcomputer 110 of the present embodiment and a circuit (clock generator 123) related to the circuit will be described with reference to FIG.

  The clock generator 123 further divides a frequency dividing circuit 231 that divides an externally supplied random number clock EXCLK, a frequency dividing circuit 232 that divides the system clock MCLK, and a clock divided by the frequency dividing circuit 232 And a CTC (counter timer circuit) circuit 233 that generates a signal for frequency-dividing and interrupting the CPU core 111 with a predetermined period. The clocks φ1 and φ2 respectively divided by the frequency dividing circuit 231 and the frequency dividing circuit 232 are supplied to the random number generation circuit 124. In this embodiment, the frequency dividing ratios of the frequency dividing circuits 231 and 232 are the same (both are divided by 1/2).

  The random number generation circuit 124 includes a random number control circuit 240 that controls the entire random number generation circuit, a random number initial value setting register 241 in which an initial value of random numbers is set by the CPU core 111 via the CPU bus 126, and a random number circuit activation register 242. And a counter circuit 243. When a predetermined value is set in the random number circuit activation register 242 by the CPU core 111, the random number control circuit 240 is configured to start control of random number generation. The count range of the counter circuit 243 can be selected from a range of 8 bits (FFh) to 16 bits (FFFFh) by setting a predetermined value in the HW parameter ROM. The random number control circuit 240 has a built-in selection circuit 252 that determines the magnitude of the frequencies of the clocks φ1 and φ2 divided by the frequency dividing circuits 231 and 232, and switches between and shuts off the clock. The counter circuit 243 is caused to perform a counting operation based on this clock. When a plurality of types of random numbers are required, a plurality of counter circuits 243 are provided, and the random number initial value setting register 241 can be configured to set different initial values for each counter circuit.

  Further, the random number generation circuit 124 artificially generates three latch registers 245, 247, and 249 that take in and hold the value of the counter circuit 243, and a start winning detection signal to the counter circuit 243. Latch register trigger circuits 244, 246, and 248 for generating a trigger signal for latching the value of. The latch register trigger circuits 244, 246, and 248 can be configured by registers. The latch registers 245, 247, and 249 normally latch the value of the counter circuit 243 based on the latch signal generated by the random number control circuit 240, but the CPU core 111 supplies a predetermined value to the latch register trigger circuits 244, 246, and 248. Is set, the latch trigger signal is generated, and the value of the counter circuit 243 is latched in the latch registers 245, 247, and 249.

  In this embodiment, as shown in FIG. 7, the counter circuit 243 is updated (counted up) by the rising edge of the clock φ1 (or φ2) divided by the frequency dividing circuit 231 or 232, while the clock φ1 (φ2 ), That is, the clock / φ1 (/ φ2) having a phase difference of 180 ° is used as the latch timing signal, so that the counter value is not latched at the timing when the value of the counter circuit changes.

  The random number control circuit 240 receives the latch signals LAT0, LAT1, and LAT2 from the interrupt controller 118, and causes the latch registers 245, 247, and 249 to latch the counter based on the inputs of the latch signals LAT0, LAT1, and LAT2. Control signal is generated. In this embodiment, the start winning detection signals DET0 and DET1 from the special drawing start switches 56a and 57b are input to the interrupt controller 118, and the value of the counter circuit 243 is latched to the latch registers 245 and 247 each time a start winning is detected. Latched to either Specifically, the interrupt controller 118 detects the start winning detection signal DET continuously over 256 clocks (25.6 μs: when EXCLK or MCLK = 20 MHz is input) with the clock signal supplied to the counter circuit 243. The latch signal LAT is output to the random number control circuit 240 at the timing. The random number control circuit 240 does not latch the counter value at the timing when the latch signal LAT is input, but any one of the latch registers 245, 247, and 249 at the rising edge of the clock signal immediately after the latch signal LAT is input. The counter value is latched in the corresponding register.

  Although not particularly limited, in this embodiment, a signal of the start port switch 1 is input to DET0 (LAT0), and when the signal is input, the counter value is latched in the latch register 245. A signal of the start port switch 2 is input to DET1 (LAT1), and when the signal is input, the counter value is latched in the latch register 247. Of the three inputs of the interrupt controller 118, one DET2 (LAT2) and the latch register 249 are provided so as to be compatible with a gaming machine in which three starting winning holes are provided in the gaming area. It is treated as a spare in gaming machines.

  Instead of the interrupt controller, a control register writable from the outside may be provided, and a counter value latch signal may be generated in response to the writing to the control register. When a control register is provided, a predetermined bit of the control register is set by the start winning detection signals DET0 and DET1, and an interrupt signal is input to the interrupt controller 118. The interrupt controller 118 performs the same control as described above. You may comprise so that it may perform.

  Further, the random number generation circuit 124 includes a status register 250 for informing the CPU core 111 of the internal state of the random number generation circuit 124 and a random number circuit initialization register 251 for initializing the random number generation circuit 124. The status register 250 is provided with a latch permission flag that permits or prohibits the latching of the counter value to the latch registers 245, 247, and 249. By setting this flag, the latch of the counter value is permitted and the flag is set. The latch can be prohibited by clearing it. In this embodiment, the latch permission flag is provided corresponding to each of the latch registers 245, 247, and 249, and is configured to be able to control permission / prohibition of latch for each register. The status register 250 is rewritten by the random number control circuit 240 so that the CPU 111 can only read and cannot write. As a result, it is possible to prevent an illegal act of rewriting the program and causing the CPU to acquire an illegal random number value.

  FIG. 8 shows a latch control procedure of the counter value to the latch register by the random number control circuit 240. In this control, first, it is determined whether any of the latch signals LAT0, LAT1, and LAT2 is input (step S101). If any of the latch signals LAT0, LAT1, and LAT2 is input, the status It is determined whether the latch permission flag of the register 250 is set (step S102). If there is no latch signal input or if there is a latch signal and the latch permission flag is not set, the control is terminated, and if it is determined in step S102 that the latch permission flag is set, the counter circuit 243 The counter value is read and stored in the corresponding latch register (any one of 245, 247, and 249) (steps S103 and S104). Subsequently, the corresponding latch permission flag of the status register 250 is set to a prohibited state, and the control is terminated (step S105).

  FIG. 9 shows a control procedure when the random number control circuit 240 reads latch data. In this control, first, it is determined whether or not the CPU core 111 has read data in the latch register (any one of 245, 247, and 249) (step S111), and when data (counter value) is read, The data in the latch register is cleared, the corresponding latch permission flag in the status register 250 is set to the permitted state, and the control is terminated (steps S112 and S113). By reading the data in the latch register, clearing it, and setting the latch enable flag to the enabled state, the counter value is no longer latched due to some sort of malfunction such as a circuit failure. There is no risk of duplicate counter values being acquired. As a result, when the value held in the counter value holding means immediately before corresponds to the big hit, it is possible to prevent the big hit from occurring continuously.

  In this embodiment, the random number control circuit 240 latches the counter value in the latch register by external start winning detection signals DET0 and DET1. On the other hand, when the start winning detection signal DET0 or DET1 is input to the microcomputer, the CPU core 111 determines that the data (counter value) in the latch register 245 or 247 is a big hit if a predetermined condition is satisfied by the program processing. Read as a random value for. The latch permission flag of the status register 250 is set to the latch prohibited state until the value of the counter is latched in the latch register and is read by the CPU.

  Therefore, by performing the control as described above, even if noise is applied to the latch signals LAT0, LAT1, and LAT2 input to the random number control circuit 240, the counter value of the counter circuit 243 is erroneously latched in the latch register. Is not (overwritten), and the CPU does not read an incorrect counter value (random number value).

  In addition, in a conventional game control circuit in which a random number generation circuit is connected as an external circuit, if a player gives a latch signal at a timing different from the original start winning detection signal by an unauthorized operation, an incorrect counter value (disturbance) In this embodiment, even if the start winning detection signals DET0 and DET1 are illegally input and the counter value is latched in the latch register, the latch data is not read by the CPU. The counter value is latched in the latch register by the start winning detection signals DET0 and DET1 that are normally generated and read by the CPU. As a result, it is difficult to acquire an erroneous random number value due to fraud, and the counter value latched based on the start winning can be reliably used in the game control.

  FIG. 10 shows a procedure of hard random number clock monitoring control by the random number control circuit 240. In this control, it is determined whether the random number clock EXCLK supplied from the outside is input to the clock generator 123 (step S121). Here, when EXCLK is input, the frequency of EXCLK and the frequency of MCLK are compared to determine whether the frequency of EXCLK is higher or not, and when it is higher, the frequency of EXCLK is equal to the frequency of MCLK. It is determined whether or not it is smaller than 1.5 times (steps S122 and S123).

  Only when both conditions are satisfied, the clock φ1 obtained by dividing EXCLK by 1/2 by the clock generator 123 is supplied to the counter circuit 243 to update the counter value (step S124). If the condition is not satisfied, MCLK is supplied to the counter circuit 243, and the system operation and the counter circuit operation are performed with the same clock. The determinations in steps S122 and S123 are actually made based on the clocks φ1 and φ2 divided by the clock generator 123. Whether the frequency of EXCLK is higher than the frequency of MCLK can be determined by providing counters for counting the respective clocks and operating them for the same time to determine the magnitude of the counter value.

  As described above, the counter circuit 243 that gives a random number value is updated only when the clocks EXCLK and MCLK satisfy a predetermined condition, so that an unauthorized person performs an illegal operation on the clock input terminal and performs an illegal operation. Even if it tries to acquire a random value, it can be prevented. In addition, since the clocks φ1 and φ2 are compared and the higher frequency clock is selected and supplied to the counter circuit 243, it becomes difficult to specify the update timing of the counter circuit 243 that generates random numbers, which is illegal. Can be made difficult to do.

  Note that the frequencies of the clocks φ1 and φ2 are compared, the clock with the higher frequency is selected and supplied to the counter circuit 243, and the clock with the lower frequency is supplied to a circuit other than the counter circuit 243 as an operation clock. You may comprise as follows. By counting the counter circuit 243 with the clock with the higher frequency, and latching the counter value into the latch register with the clock with the lower frequency, the target value is latched with an illegal operation than the reverse case. Can make it difficult.

  In this embodiment, when it is determined in steps S122 and S123 that the condition is not satisfied, MCLK is supplied to the counter circuit 243. However, when it is determined that the condition is not satisfied, MCLK is supplied. Further, the supply of EXCLK may not be performed to the counter circuit, and the counter circuit may be disabled.

  Note that it is possible to select either EXCLK or MCLK by providing a clock selection register in the random number generation circuit and setting a predetermined value in the clock selection register via the HW parameter ROM.

  Next, game control executed by the game microcomputer (referred to as game microcomputer) 110 of the game control apparatus 100 will be described.

  The control process by the gaming microcomputer 110 mainly includes a main process shown in FIGS. 11 and 12 and a timer interrupt process shown in FIG. 13 performed at a predetermined time period (for example, every 2 msec).

  The main process is started when the power is turned on. In this main process, as shown in FIG. 11, first, an interrupt prohibition process (step S1) is performed, and then an interrupt vector setting process (step S1) for setting a jump destination vector address to be executed when an interrupt occurs. S2), a stack pointer setting process (step S3) for setting a stack pointer that is the start address of an area in which a value of a register or the like is saved when an interrupt occurs, and an interrupt mode setting process (step S4) for setting an interrupt processing mode. )I do.

  Next, access to a readable / writable RWM (read / write memory) such as RAM or EEPROM is permitted, and all output ports are set to OFF (no output) (steps S5 and S6). Thereafter, it is determined whether or not the clear switch 162 of the backup memory in the power supply device 160 is turned on (step S7). If the clear switch is off, in step S8, after checking the data in the power failure check area in the RWM, check the code for checking whether or not the power failure is restored and the normal / abnormal data called checksum. (Steps S9 and S10).

  If it is determined in step S9 that the power failure has been restored and it is determined in step S10 that the checksum is normal, in step S11, an initial value at the time of power failure recovery is set in the readable / writable RWM, and then the game frame state is set. The memory area in which such data is stored is cleared, a power failure recovery command is transmitted to other control devices (steps S12 and S13), and the process proceeds to step S17 in FIG. On the other hand, if it is determined in step S9 that the power failure has not been restored, or if the checksum is determined to be abnormal in step S10, the read / writeable RWM in use is cleared in step S14. Then, after the initial value at power-on is saved in the RWM, processing for transmitting a power-on command to other control devices (steps S15 and S16) is performed, and the process proceeds to step S17 in FIG.

  If it is determined in step S7 that the clear switch is on, the process jumps to step S14 to clear the read / writeable RWM being used, save the initial value at power-on in the RWM, and so on. Processing for transmitting a power-on command to the control device (steps S15 and S16) is performed, and the process proceeds to step S17 in FIG.

  In step S17, an interrupt timer is started. In next step S18, a code for starting the circuit is set in the random number circuit starting register 242 (see FIG. 6) in the random number generating circuit, and the random number generating circuit 124 is started. Thereafter, interruption is temporarily prohibited (step S19), and an initial value random number update process (step S20) is performed to update the initial value of a random number such as a jackpot determination random number and destroy the temporal regularity of the random number. Then, processing for permitting interruption (step S21) and processing for checking data in the power failure inspection area (step S22) are performed. Then, a determination is made as to whether or not a power failure has occurred (step S23). If no power failure has occurred (No), the process returns to the processing for prohibiting the above-described interrupt (step S19), and steps S19 to S23 are performed. Repeat the process.

  On the other hand, if it is determined in step S23 that a power failure has occurred (Yes), processing for temporarily prohibiting interruption (step S24), processing for turning off all output ports (step S25), and clearing the power failure inspection area The process (step S26) to perform is performed. After that, the process of saving the power failure recovery inspection area check data in the power failure recovery inspection area (step S27) and the process of calculating the checksum when the RWM is turned off (step S28) are performed, and access to the RWM is prohibited. After performing the process (step S29) to be performed, it waits for the power supply of the gaming machine to be cut off. In this way, the check data is saved in the power failure recovery inspection area and the checksum at the time of power shutdown is calculated, so that whether or not the information stored in the RWM before the power shutdown is correctly backed up can be checked. This can be determined when the power is turned on again.

  Next, the timer interrupt process in FIG. 13 will be described. This timer interrupt process is started, for example, every 2 ms when a periodic timer interrupt signal generated by the CTC circuit 233 in the clock generator 123 is input. When a timer interrupt occurs in the gaming microcomputer 110, the timer interrupt process of FIG. 13 is started.

When the timer interrupt process is started, a register saving process (step S30) is performed in which a value held in a predetermined register is first transferred to the RAM. Next, an input process (step S31) for capturing inputs from various sensors (special drawing start switches 56a and 57b, a general drawing start switch 54a, a frame opening switch 12a, a ball break switch 41a, etc.) is performed. Then, based on the output data set in various processes, an output process (step S32) for performing drive control of an actuator such as a solenoid (large winning opening SOL10b, general electric power SOL7b) or the like is performed. As for the input from the switch for detecting the winning and passing of the game ball, the input port is read every 2 ms in the input process of step S31, the chattering removal state is analyzed, and the switch level state is 0. When it changes from 1 to 1, the switch is turned on. Further, in the input process of step S31, as a method of eliminating chattering for the input of the switch when acquiring the input port state, the port state of the switch to be analyzed is read out from the input port for each interrupt and extracted. If the continuous data for two interrupts match, the state is set to a normal port state. Then, the state is determined as the level state and the level state is updated. If the data does not match, the previous level state is continued. Further, the rising edge is updated according to the change of the level state. At this time, the updated rising edge is stored in the RAM. The above processing is performed in all the switches that detect winning and passing of game balls.

  Next, command transmission processing (step S33) and random number update processing (step S34) for outputting commands set in the transmission buffer in various processings to the effect control device 150 and the payout control device 200 are performed. In this random number update process (step S34), the jackpot determination random number for determining the hit loss of the special figure variation display game and the big hit symbol random number for determining the jackpot symbol of the special figure variation display game are updated (taken in). I do. In addition, a winning random number for determining the hit variation of the normal figure fluctuation display game and a fluctuation pattern random number for determining the fluctuation pattern in the special figure fluctuation display game are updated (taken in).

  Next, a special drawing start switch 56a, 57b, an ordinary drawing start switch 54a, a winning opening switch 55a ... 55n, a winning opening switch for monitoring whether there is a normal signal input from the count switch 58a, and monitoring errors. / An error monitoring process (step S35) is performed. Also, a special figure game process (step S36) for performing a process related to the special figure variation display game and a general figure game process (step S37) for performing a process related to the common figure variation display game are performed.

  Next, segment LED editing processing (step S38) is performed (step S38), which is provided in the gaming machine 10 and drives the segment LEDs that display various information related to the game to display desired contents. Then, external information editing processing (step S39) for setting a signal to be output to the external management apparatus in the output buffer is performed. Subsequently, the process of declaring the end of the interrupt (step S40) is performed, the process of restoring the saved register data (step S41), the process of permitting the interrupt (step S42), and the timer interrupt The process ends.

  Next, details of the special figure game process (step S36) in the timer interrupt process of FIG. 13 will be described with reference to FIG.

  As shown in FIG. 14, in the special game process, first, the winning (special drawing start SW1, SW2) is monitored and the winning detection is performed on the normal variable winning device 57 having the start winning port 56 and the second starting winning port. The start port switch monitoring process (step S361) for acquiring and storing various random number values based on the above is executed. The start port switch monitoring process includes a start port SW1 monitoring process (start port switch 1 monitoring process) for monitoring the winning of the start winning port 56 and a start port SW2 monitoring process (starting) for monitoring the winning to the normal variation winning device 57. Mouth switch 2 monitoring process). Thereafter, a count switch monitoring process (step S362) for monitoring the input from the count switch 58a in the special variable winning device 58 and counting the number of inputs is executed.

  Next, it is determined whether or not the game process timer set in each process relating to the execution of the special figure variation display game has expired (step S363). If it is determined that the game process timer has not timed up (No), the special figure variation control process (step S375) relating to the control of the special figure variation display game is performed and the special figure game process is terminated. In addition, in the determination of whether or not the game processing timer has expired (step S363), if it is determined that the game processing timer has expired (Yes), the game provided for reasonably progressing the game A game branching process (step S364) for selecting a process to be executed next based on the process number is performed.

  In the game branching process (step S364), when it is determined that the game process number is “0”, the special symbol variation start is monitored, the special symbol variation start setting, the effect setting, or the special graphic routine processing A special figure routine process (step S365) for setting information necessary for performing the process is performed. Further, in the game branching process (step S364), when it is determined that the game process number is “1”, the special figure first half fluctuation start process (step for setting information related to the first half fluctuation time of the special figure fluctuation display game) S366) is performed. The first half variation time is a period from the start of the special figure variation display game to the occurrence of the reach state. On the other hand, in the game branching process (step S364), when it is determined that the game process number is “2”, the special figure latter half fluctuation start process (step for setting information related to the latter half fluctuation time of the special figure fluctuation display game) (step S364) S367) is performed. The second half variation time is a period from the occurrence of the reach state to the end of the special figure variation display game.

  Also, in the game branching process (step S364), when it is determined that the game process number is “3”, the updating of the symbol and the symbol during the variation of the decorative special symbol variation display game executed on the display device 61 are temporarily performed. A special figure changing process (step S368) for performing control such as changing again after stopping is performed. Also, in the game branching process (step S364), when it is determined that the game process number is “4”, a special figure display process (step for setting a final symbol stop timing in the special figure variation game) S369) is performed.

  Further, in the game branching process (step S364), when it is determined that the game process number is “5”, the sound effect in the special gaming state (big hit), the light emission drive of the lighting unit 17, a predetermined interval (for example, 1 second) A fanfare / interval process (step S370) is performed for performing a plurality of opening operation processes of the special variable winning device 58 (large winning opening) sandwiching the.

  Further, in the game branching process (step S364), when it is determined that the game process number is “6”, a special winning opening opening process (step S371) is performed. In the special prize opening opening process (step S371), if the special gaming state is not the final round, information necessary for performing the fanfare / interval processing (step S370) is set, and the special gaming state is the final round. If there is, the setting of the command for the special game state end screen and the setting of information necessary for performing the next big winning opening remaining ball process (step S372) are performed.

  Further, in the game branching process (step S364), when it is determined that the game process number is “7”, all the game balls remaining in the big prize opening after the big prize opening is closed are detected by the count switch 58a. The winning ball remaining ball processing (step S372) for setting the time until the time is performed. Further, in the game branching process (step S364), when it is determined that the game process number is “8”, the special game state is terminated and the special figure routine process (step S365) is performed. A jackpot ending process (step S373) for setting necessary information is performed.

  Furthermore, after performing each of the above-described processes based on the game process number, the table data saving process (step S374) for saving various set data is performed, and then a process such as updating the game process timer is performed. A control process (step S375) is performed to end the special figure game process.

  Next, details of the first embodiment of the first invention of the start port SW2 monitoring process (start port switch 2 monitoring process) executed in the start port switch monitoring process (step S361) of FIG. 14 will be described with reference to FIG. I will explain.

  In the start port SW2 monitoring process (start port switch 2 monitoring process), first, it is determined whether or not the normal variation winning device 57 is in operation, that is, the open state in which the normal variation winning device 57 is activated and the game ball can be won. It is determined whether or not (step S611). In this determination, when the normal variation winning device is in operation (Yes), the process jumps to step S613 to determine whether the start port switch 2 (57b) is on. If it is determined in step S611 that the normally variable winning device is not in operation (No), it is determined in the next step whether or not the number of illegal winnings is an upper limit (step S612). In the determination of the start port switch in step S613, the presence or absence of the rising edge corresponding to the start port switch stored in the RAM in the input process in step S31 of FIG. ", It is determined that the switch state is ON, and when the updated rising edge is" NONE ", it is determined that the switch state is OFF.

  The normally variable winning device 57 cannot win game balls in the closed state, and can win game balls only in the open state. Therefore, when a game ball wins in a closed state, it is a case where some abnormality or fraud occurs, and when there is a game ball won in such a closed state, the number is counted as an illegal winning number. ing. Then, in determining whether or not the number of illegal winnings is an upper limit value (step S612), it is determined whether or not the number of illegal winnings counted in this way is equal to or greater than a predetermined upper limit value. In this determination, when the number of illegal winnings is the upper limit (Yes), the start port SW monitoring process is terminated. That is, in this case, the start memory is not generated. If it is determined in step S612 that the number of illegal winnings is not the upper limit (No), it is determined in step S613 whether the start port switch 2 (57b) is on.

  If it is determined in step S613 that the start port switch 2 is not on, the start port SW2 monitoring process is terminated. On the other hand, if it is determined in step S613 that the start port switch 2 is on, the process proceeds to step S614, and a start port signal output count update process for updating the number of winning game balls to the normal variation winning device 57 ( Step S614) is performed.

  Next, it is determined whether or not the starting memory number is the upper limit value (step S615). If the starting memory number is not the upper limit value (No) in this determination, the starting memory number is determined in the next step S616. After the increment (+1), the value of the latch register (245, 247, 249) is acquired as a big hit random value and stored in a predetermined area of the RAM (113) (step S617).

  Thereafter, a process of acquiring the big hit symbol random number and storing it in the RAM (step S618), and a process of acquiring the fluctuation pattern random number and storing it in the RAM (step S619). Further, the decorative special figure start memory number command to be transmitted to the effect control device 150 is set in the transmission circuit, and the start port SW2 monitoring process is terminated (step S620).

  If it is determined in step S615 that the start memory number is the upper limit value (Yes), that is, if no more start memory can be stored, the process proceeds to step S621, where the latch registers (245, 247, 249) is obtained, that is, only reading is performed, and the start port SW2 monitoring process is terminated. Even when the starting memory number is the upper limit value, the value of the latch register (245, 247, 249) is acquired, and as described in the latch data reading control process in FIG. When this is done, the counter value can be taken into the latch register from the counter circuit.

  Further, in the starting port switch monitoring process (step S361) of FIG. 14, the starting port SW1 monitoring process (starting port switch 1 monitoring process) is executed following the above-described starting port switch 2 monitoring process. The start port switch 1 monitoring process is substantially the same as the start port switch 2 monitoring process.

  The difference between the start port switch 2 monitoring process and the start port switch 1 monitoring process is that, in the start port switch 1 monitoring process, whether or not the normal variation winning device 57 in step S611 of the start port switch 2 monitoring process of FIG. In step 613, the start port switch 1 (56a) is turned on instead of the start port switch 2 (57b). The point is whether or not there is a determination.

  FIG. 16 shows a second embodiment of the first invention of the start port SW2 monitoring process (start port 2 monitoring process) executed in the start port switch monitoring process (step S361) of FIG. The difference between the start port switch 2 monitoring process in FIG. 16 and the start port switch 2 monitoring process in FIG. 15 is that the start port switch 2 monitoring process in FIG. 15 determines the start memory number in step S615 as an upper limit value or not. The process of acquiring the value of the latch register (step S621) to be executed when it is determined as “Yes” (step S621) is performed before the determination as to whether or not the start memory number in step S615 is the upper limit in the start port switch 2 monitoring process of FIG. It is in the point that it tries to do.

  Also in the start port switch 2 monitoring process (start port SW2 monitoring process) of this embodiment, when the start winning memory reaches the upper limit number, the counter value held in the latch register as the counter value holding means becomes a big hit random number or the like. Therefore, when the start winning is detected next time, the counter value is permitted to be taken into the latch register from the counter circuit, and the desired counter value is set when the start winning memorized number becomes smaller than the upper limit number. The counter value is stored in the counter value holding means. Further, if the start winning memorized number has reached the upper limit number, the acquired counter value is not stored in the start winning memorizing means (RAM), so that the determination by the wrong counter value is avoided. Further, in this embodiment, since the value of the latch register is acquired before determining whether or not the start memory number is the upper limit value, the counter value read from the latch register is stored in the start winning storage means. Will be held in a predetermined area (buffer) until the data is read, and it is possible to avoid the idle reading that simply reads the counter value and does not hold it anywhere like the embodiment of FIG. Can be eliminated.

  Next, a third embodiment of the first invention of the start port SW2 monitoring process (start port 2 monitoring process) executed in the start port switch monitoring process (step S361) of FIG. 14 will be described with reference to FIGS. It explains using. In the third embodiment, a random number latch interrupt process as shown in FIG. 17 is provided as one of interrupt processes for the CPU 111. Then, when the number of times of input of the hard latch signal updated during this interrupt processing is monitored during the start port switch monitoring processing of FIG. 18, when there is an abnormality, the counter value of the counter circuit is latched again in the latch register. There is a feature in making it.

  In this embodiment, based on the start winning detection signal (DET0 to DET2) being input to the interrupt controller 118, a signal (hard latch signal) LAT0 instructing the latch supplied from the interrupt controller 118 to the random number control circuit 240. When .about.LAT2 is input to the CPU 111, the random number latch interrupt process of FIG. 17 is started. Instead of the hard latch signals LAT0 to LAT2 supplied to the random number control circuit 240, a signal output from the random number control circuit 240 to the latch register may be input to the CPU 111 as an interrupt signal to start processing.

  When this random number latch interrupt processing is started, the interrupt is first prohibited, and the values held in various registers in the gaming microcomputer 110 are saved to the stack area in the RAM 113, and then the number of hard latch signal inputs is updated. (Increment) (steps S81 to S83). Thereafter, the end of the interrupt is declared and the value of the register saved in step S82 is restored to the original register, and then the interrupt is permitted and the process is terminated (steps S84 to S86).

  In the starting port SW2 monitoring process (starting port switch 2 monitoring process) in FIG. 18, first, it is determined whether or not the normal variation winning device 57 is in operation, that is, the normal variation winning device 57 is activated and a game ball can be won. It is determined whether or not it is in the open state (step S631). In this determination, when the normal variation winning device is in operation (Yes), the process jumps to step S633 to determine whether or not the start port switch 2 (57b) is on. If it is determined in step S631 that the normally variable winning device is not in operation (No), it is determined in the next step whether or not the number of illegal winnings is an upper limit (step S632).

  The normally variable winning device 57 cannot win game balls in the closed state, and can win game balls only in the open state. Therefore, when a game ball wins in a closed state, it is a case where some abnormality or fraud occurs, and when there is a game ball won in such a closed state, the number is counted as an illegal winning number. ing. In the determination of whether or not the number of illegal winnings is the upper limit (step S632), it is determined whether or not the number of illegal winnings counted in this way is equal to or greater than a predetermined upper limit. In this determination, when the number of illegal winnings is the upper limit (Yes), the start port SW monitoring process is terminated. That is, in this case, the start memory is not generated. If it is determined in step S632 that the number of illegal winnings is not the upper limit (No), it is determined in step S633 whether the start port switch 2 (57b) is on.

  If it is determined in step S633 that the start port switch 2 is not on, the start port SW2 monitoring process is terminated. On the other hand, if it is determined in step S633 that the start port switch 2 is ON, the process proceeds to step S634, and a latch register value acquisition process (step S634) is performed. Next, a start port signal output number updating process for updating the number of winnings of game balls to the normal variation winning device 57 is performed.

  Subsequently, it is determined whether or not the start memory number is the upper limit value (step S636). If the start memory number is the upper limit value in this determination, the monitoring process is terminated and the start memory number is not the upper limit value. If this is the case, in the next step S637, the number of start-port switches and the number of hard latch signal inputs are compared to determine whether the number of hard latch signal inputs is abnormal. Here, the abnormality of the hard latch signal input count is a case where the hard latch signal input count is considerably larger than the start opening switch count. The number of hard latch signal inputs compared to the number of start port switches when a false start detection signal is input due to noise or a false start detection signal is input by the player to illegally generate a big hit. Therefore, by making the determination in step S637, it is possible to prevent malfunction and fraud due to noise as described above.

  If it is determined in step S637 that there is an abnormality (Yes), one of the latch register trigger circuits 244, 246, 248 (see FIG. 6) is set in the next step S638, and a latch signal is generated by software processing. With this latch signal, the value of the counter circuit 243 is latched in one of the latch registers 245, 247, and 249. In step S639, the value of the latch register is acquired, and the process proceeds to step S640. On the other hand, if it is determined in step S637 that there is no abnormality (No), the process jumps to step S640. In step S640, the register value acquired in step S633 or the register value acquired in step S639 is stored in the RAM as a big hit random number.

  After that, after updating (incrementing) the starting memory number in step S641, processing for acquiring the big hit symbol random number and storing it in the RAM (step S642), processing for acquiring the fluctuation pattern random number and storing it in the RAM (step S643) is performed. Further, a process for setting a decoration special figure start memory number command to be transmitted to the effect control device 150 is performed in the transmission circuit (step S644), and the start port SW2 monitoring process is terminated.

  Further, in the starting port switch monitoring process (step S361) of FIG. 14, the starting port SW1 monitoring process (starting port switch 1 monitoring process) is executed following the above-described starting port switch 2 monitoring process. The start port switch 1 monitoring process is substantially the same as the start port switch 2 monitoring process.

  The difference between the start port switch 2 monitoring process and the start port switch 1 monitoring process is that in the start port switch 1 monitoring process, the normal variation winning device 57 in step S631 of the start port switch 2 monitoring process of FIG. 18 is operating. In step S632, the start opening switch 1 (56a) is turned on instead of the start opening switch 2 (57b). The point is whether or not there is a determination.

  FIG. 19 shows a random number latch interrupt as one of the interrupt processes executed based on the signal input from the outside separately from the timer interrupt process (FIG. 13) in the second and third embodiments. The processing procedure is shown.

  This random number latch interrupt processing is a signal (hard latch signal) that instructs the latch supplied from the interrupt controller 118 to the random number control circuit 240 based on the input of the start winning detection signal (DET0 to DET2) to the interrupt controller 118. ) It is started when LAT0 to LAT2 are input to the CPU 111. Instead of the hard latch signals LAT0 to LAT2 supplied to the random number control circuit 240, a signal output from the random number control circuit 240 to the latch register may be input to the CPU 111 as an interrupt signal to start processing.

  When this random number latch interrupt process is started, the interrupt is first prohibited and the values held in the various registers in the gaming microcomputer 110 are saved to the stack area in the RAM 113, and then the latch registers (245, 247, 249) is acquired, and the acquired value is stored in a latch random number area which is a buffer area in the RAM (steps S51 to S54). Thereafter, the end of the interrupt is declared and the value of the register saved in step S52 is restored to the original register, and then the interrupt is permitted and the process is terminated (steps S55 to S57).

  Next, the details of the start port switch 2 monitoring process (step S361) in the second and third embodiments of the special invention game process of FIG. 14 executed in the start port SW monitoring process (step S361) are shown in FIG. 20 will be described.

  In the start port SW2 monitoring process (start port switch 2 monitoring process), first, it is determined whether or not the normal variation winning device 57 is in operation, that is, the open state in which the normal variation winning device 57 is activated and the game ball can be won. It is determined whether or not (step S611). In this determination, when the normal variation winning device is in operation (Yes), the process jumps to step S613 to determine whether the start port switch 2 (57b) is on. If it is determined in step S611 that the normally variable winning device is not in operation (No), it is determined in the next step whether or not the number of illegal winnings is an upper limit (step S612).

  The normally variable winning device 57 cannot win game balls in the closed state, and can win game balls only in the open state. Therefore, when a game ball wins in a closed state, it is a case where some abnormality or fraud occurs, and when there is a game ball won in such a closed state, the number is counted as an illegal winning number. ing. In step S612, it is determined whether or not the number of illegal prizes thus counted is equal to or greater than a predetermined upper limit value. In this determination, when the number of illegal winnings is the upper limit value (Yes), the start port SW2 monitoring process is terminated. That is, in this case, the start memory is not generated. If it is determined in step S612 that the number of illegal winnings is not the upper limit (No), it is determined in step S613 whether the start port switch 2 (57b) is on.

  If it is determined in step S613 that the start port switch 2 is not on, the start port SW2 monitoring process is terminated. On the other hand, if it is determined in step S613 that the start port switch 2 is on, the process proceeds to step S614 to start the start port signal for updating the number of winning game balls to the start winning port 56 and the normal variation winning device 57. An output count update process (step S614) is performed.

  Next, it is determined whether or not the starting memory number is the upper limit value (step S615). If the starting memory number is not the upper limit value (No) in this determination, the starting memory number is determined in the next step S616. After the increment (+1), the value stored in the latch random number area in the RAM in step S54 in FIG. 15 is stored in the predetermined area in the RAM (113) as the big hit random number value (step S617). Then, a predetermined loss value (fixed value) is stored in the latch random number area (step S618). Instead of storing the lost value, the stored value may be cleared to “all 0” or set to a fixed value such as “all 1”. Thus, by storing a fixed value in the latch random number area after storing it as a random number value, even if the random number latch interrupt processing is not performed due to some trouble such as a circuit failure, the acquired counter value is duplicated. Thus, it can be prevented from being stored as a random value. As a result, when the value held in the latch random number area immediately before corresponds to the big hit, it is possible to prevent the big hit from occurring. Note that step S618 may be omitted.

  Thereafter, a process of acquiring the big hit symbol random number and storing it in the RAM (step S619), and a process of acquiring the fluctuation pattern random number and storing it in the RAM (step S620). Furthermore, the process of setting the decoration special figure start memory number command to be transmitted to the effect control device 150 is set in the transmission circuit (step S621), and the start port SW2 monitoring process is terminated. Further, when it is determined in step S615 that the start memory number is the upper limit value (Yes), that is, when the start memory cannot be stored any more, the start port SW2 monitoring process is terminated.

  Further, in the starting port switch monitoring process (step S361) of FIG. 14, the starting port SW1 monitoring process (starting port switch 1 monitoring process) is executed following the above-described starting port switch 2 monitoring process. The start port switch 1 monitoring process is substantially the same as the start port switch 2 monitoring process.

  The difference between the start port switch 2 monitoring process and the start port switch 1 monitoring process is that, in the start port switch 1 monitoring process, the normal variation winning device 57 in step S611 of the start port switch 2 monitoring process of FIG. 20 is operating. In step 613, the start port switch 1 (56a) is turned on instead of the start port switch 2 (57b). The point is whether or not there is a determination.

  Based on the input of the start detection signal from the outside, the value of the counter circuit 243 is latched in the latch registers 245, 247, and 249 in the random number generation circuit 124, and then the value held in the latch register in the timer interrupt processing is used as the random number value. In the case of acquisition, noise is generated in the random number generation circuit 124 between the input of the start detection signal and the start of the timer interrupt process, and the value of the counter circuit 243 is erroneously set to the latch registers 245, 247, and 249 by the noise. If the counter value is latched by any of the above, there is a possibility that the counter value taken into the latch register due to noise is acquired as a random value by the CPU.

  However, as in the above embodiment, the value held in the latch register is acquired as a random value by the random number latch interrupt process of FIG. 15 executed by the CPU based on the input of the start detection signal, and the timer interrupt process thereafter. By storing the random number value already acquired in the start port switch 2 monitoring process executed in step 2 as a regular random number value, it is latched by noise generated between the input of the start detection signal and the start of the timer interrupt process. It is possible to prevent an erroneous random number value from being used for the determination.

  FIG. 21 shows a procedure of random number latch interrupt processing as one of interrupt processing executed based on signal input from the outside separately from the timer interrupt processing (FIG. 13) in the embodiment of the fourth invention. Has been. In the flowchart of FIG. 21, the game board is provided with two start winning openings (56 and 57 in FIG. 3), so that different types of variable display games are executed depending on the winning at each start winning opening. When game control is set, when a start winning occurs after the process by one timer interrupt is finished and the next timer interrupt process is started (2 msec in the embodiment), The winning order can be distinguished and memorized. In the following description, the start winning port 56 is referred to as “start port 1”, and the start winning device 57 is referred to as “start port 2”. The latch registers 245 and 247 are also fixed to the start port 1 and the start port 2 corresponding to the start winning ports. In this way, for example, the special figure 1 fluctuates by winning the start opening 1, and the special figure 2 fluctuates by winning the starting opening 2. When performing game control with different game values, it is possible to prevent a wrong game value from being given by accurately determining the winning order.

  This random number latch interrupt processing is a signal (hard latch signal) LAT0 instructing the latch supplied from the interrupt controller 118 to the random number control circuit 240 based on the start winning detection signal DET0 or DET1 being input to the interrupt controller 118. Alternatively, it is started by inputting LAT1 to the CPU 111. Instead of the hard latch signals LAT0 and LAT1 supplied to the random number control circuit 240, a signal output from the random number control circuit 240 to the latch register may be input to the CPU 111 as an interrupt signal to start processing.

  When this random number latch interrupt processing is started, the interrupt is first prohibited and the values held in the various registers in the gaming microcomputer 110 are saved to the stack area in the RAM 113, and then the corresponding latch register 245 or 247 is stored. Is acquired (steps S51 to S53). Subsequently, it is determined by referring to the latch permission flag of the status register 250 corresponding to the latch register 245 whether or not the latch register 245 is prohibited from latching (step S54). This is because the prohibition flag is set when the counter value is latched based on the start winning.

  If it is determined in step S54 that it is “latching prohibited” (Yes), the starting port number of the starting port 1 is acquired in the next step S55, and if it is determined that it is not “latching prohibited” (No), In step S56, the start port number of the start port 2 is acquired. The starting port number may be stored in the ROM, or may be stored in a predetermined area of the RAM in the program initialization process. Thereafter, the “previous start opening prize information area” and “rear start opening prize information area” in the start opening prize information storage area as shown in FIG. 22 prepared in the RAM (113) are examined, and the data is “0”. It is determined whether or not (step S57).

  Here, if the data are both “0” (Yes), the starting port number acquired in step S55 is stored in the “starting port number information” column of the “first starting port winning information area” in FIG. (Step S58), the value of the latch register acquired in Step S53 is divided and stored in the “Random number (upper)” and “Random number (lower)” fields of the “First starting entry prize information area” in FIG. 22 (Step S59). . On the other hand, if it is determined in step S57 that the data is not “0” (No), the process proceeds to step S60, and the starting port number information acquired in step S55 or S56 is “first starting port winning information area” “ It is determined whether or not it matches the “starting port number information”. Here, if the numbers match, the value of the latch register acquired in step S53 is overwritten in the “random number (upper)” and “random number (lower)” fields of the “pre-start opening prize information area” (step S61). ). Thus, even when the latch register latches the counter value due to noise, the value of the latch register acquired by the random number latch interrupt process can be stored.

  If it is determined in step S60 that the numbers do not match (No), the starting port number acquired in step S55 is set in the “starting port number information” in the “rear starting port winning information area” in FIG. (Step S62), and the value of the latch register acquired in step S53 is stored separately in the "Random number (upper)" and "Random number (lower)" fields of the "Rear start opening prize information area" in FIG. (Step S63). Thereafter, after the end of the interrupt is declared in step S64, the value of the register saved in step S52 is restored to the original register, and then the interrupt is permitted and the process is terminated (steps S65 and S66). By performing the processing as described above, even when a game ball wins in succession at the start port 1 and the start port 2, the counter values latched in the latch registers in accordance with the order are accurately stored as each random number value. be able to.

  Next, the details of the start port switch monitoring process (step S361) in the embodiment of the fourth invention executed in the special figure game process of FIG. 14 will be described with reference to FIGS.

  As shown in FIG. 23, in the start port SW monitoring process (start port switch monitoring process), first, data is stored in the “first start port winning information area” and “rear starting start winning information area” in FIG. It is determined whether or not (step S601). If the data is not stored, the monitoring process is terminated. If the data is stored, the “start port number information” in the “previous start port winning information area” is started in the next step S602. It is determined whether the mouth 1 or not. When the “start port number information” is the start port 1, the start port SW1 monitoring process S610 (FIG. 24) is executed, and then the start port SW2 monitoring process S630 (FIG. 25) is executed. When “information” is not the start port 1, that is, the start port 2, the start port SW2 monitoring process S630 (FIG. 25) is executed, and then the start port SW1 monitoring process S610 (FIG. 24) is executed. The difference between the start port SW1 monitoring process S610 (FIG. 24) and the start port SW2 monitoring process S630 (FIG. 25) is that the start port SW1 monitoring process S610 (FIG. 24) is different from the start port SW2 monitoring process S630 (FIG. 25). This is the point that the determination in step S611 and the determination in step S612 that are performed first do not exist. First, the start port SW2 monitoring process S630 will be described.

  In the start port SW2 monitoring process S630, as shown in FIG. 25, first, it is determined whether or not the normal variation winning device 57 is in operation, that is, the normal variation winning device 57 is activated and the game ball can be won. It is determined whether or not (step S611). In this determination, when the normally variable winning device is operating (Yes), the process jumps to step S613 to determine whether or not the start port switches (56a, 57b) are on. If it is determined in step S611 that the normally variable winning device is not in operation (No), it is determined in the next step whether or not the number of illegal winnings is an upper limit (step S612).

  The normally variable winning device 57 cannot win game balls in the closed state, and can win game balls only in the open state. Therefore, when a game ball wins in a closed state, it is a case where some abnormality or fraud occurs, and when there is a game ball won in such a closed state, the number is counted as an illegal winning number. ing. In step S612, it is determined whether or not the number of illegal prizes thus counted is equal to or greater than a predetermined upper limit value. In this determination, when the number of illegal winnings is the upper limit value (Yes), the start port SW2 monitoring process is terminated. That is, in this case, the start memory is not generated. If it is determined in step S612 that the number of illegal winnings is not the upper limit (No), it is determined in step S613 whether or not the start port switches (56a, 57b) are on.

  If it is determined in step S613 that the start port switch is not on, the start port SW2 monitoring process is terminated. On the other hand, if it is determined in step S613 that the start port switch is on, the process proceeds to step S614, and a start port signal output for updating the number of winning game balls to the start winning port 56 and the normal variation winning device 57 is updated. Update the number of times.

  Next, it is determined whether or not the starting memory number is the upper limit value (step S615). If it is determined in this determination that the starting memory number is the upper limit value (Yes), that is, starting memory is further stored. If it cannot be stored, the start port SW2 monitoring process is terminated.

  If it is determined in step S615 that the starting memory number is not the upper limit value (No), the starting memory number is incremented (+1) in the next step S616, and then the “first starting port winning information area” in FIG. Similarly, the value stored in the random number area is stored as a big hit random number value in a predetermined area in the RAM (113) (step S617). Then, the value stored in the “rear start opening prize information area” is shifted to the “previous start opening prize information area” and stored, and the “rear start opening prize information area” after the shift is cleared (the stored value is “ 0 ”(steps S618 and S619).

  Here, if significant values are stored in the “previous start opening prize information area” and the “rear start opening prize information area”, the stored value of the “following start opening prize information area” is “previous start opening prize information area”. The shift to the “winning information area” is cleared, and the “post-start opening winning information area” is cleared. In the case where a significant value is stored only in the “pre-start opening prize information area”, the value of the “post-start opening prize information area” is originally “0”, which is the “pre-start opening prize information area”. By shifting to, the “preliminary start opening prize information area” is cleared. In addition, when the start port SW2 monitoring process is performed after the start port SW1 monitoring process, the “rear start port winning information area” is cleared after the shift in the start port SW1 monitoring process, and the “after By shifting the value (“0”) of the “start opening prize information area” to the “previous starting opening prize information area”, the “previous start opening prize information area” is cleared.

  After the above process, a process of acquiring the jackpot symbol random number and storing it in the RAM (step S620), a process of acquiring the fluctuation pattern random number and storing it in the RAM (step S621), and further transmitting the decoration feature to the effect control device 150. The process of setting the figure start memory number command in the transmission circuit is performed (step S622), and the start port SW2 monitoring process is terminated.

  As described above, by reading the value in the start opening prize information storage area, storing it as a big hit random number value, and then clearing it, there is no possibility of acquiring the acquired random number value in duplicate. Thereby, when the random number value stored in the start opening prize information storage area immediately before corresponds to the big hit, it is possible to prevent the big hit from being generated. In addition, after shifting the value of the “next start opening prize information area” to the “previous start opening prize information area”, by clearing the “after start opening prize information area”, the information of the “first start opening prize information area” is changed. The clearing operation is omitted, the counter value (random number) reading operation is simplified, the processing speed is increased, and the program capacity can be reduced. Further, it is possible to prevent a malfunction in which the counter value (random number) once acquired is acquired again.

  FIG. 26 shows a procedure of random number latch interrupt processing as one of interrupt processing executed based on signal input from the outside separately from the timer interrupt processing (FIG. 13) in the first embodiment of the fifth invention. It is shown.

  This random number latch interrupt processing is a signal (hard latch signal) that instructs the latch supplied from the interrupt controller 118 to the random number control circuit 240 based on the input of the start winning detection signal (DET0 to DET2) to the interrupt controller 118. ) It is started when LAT0 to LAT2 are input to the CPU 111. Instead of the hard latch signals LAT0 to LAT2 supplied to the random number control circuit 240, a signal output from the random number control circuit 240 to the latch register may be input to the CPU 111 as an interrupt signal to start processing.

  When this random number latch interrupt process is started, interrupts are first prohibited and the values held in the various registers in the gaming microcomputer 110 are saved to the stack area in the RAM 113 (steps S51 and S52). Then, a delay timer including a soft timer provided in the RAM 113 or the like is updated (+1), and it is determined whether or not the delay timer has expired (steps S53 and S54). If the delay timer has not expired, the process returns to step S53 to update the timer. When the delay timer expires, the process proceeds to step S55, the counter value held in the latch registers (245, 247, 249) is acquired, and the acquired value is latched as a buffer area in the RAM. Store in the random number area.

  Next, the counter value acquired in step S55 is added to the value of the delay timer, and the added value is set in the delay timer (steps S56 and S57). Thereafter, the end of the interrupt is declared and the value of the register saved in step S52 is restored to the original register, and then the interrupt is permitted and the process is terminated (steps S55 to S57). Since the counter value acquired in step S55 is different every time, the values obtained by adding the acquired counter value to the delay timer value are set in the delay timer as in steps S56 and S57, so that steps S53 and S54 are performed. The time required to exit, that is, the delay time can be made random. As a result, even if it is attempted to illegally acquire the counter value of the latch register, it is difficult to specify the acquisition timing, and illegal activities can be prevented.

  Next, details of the start port switch monitoring process (step S361) in the embodiment of the fifth invention executed in the start port switch monitoring process (step S361) of the special figure game process of FIG. 14 will be described with reference to FIG. To do.

  In the start port SW2 monitoring process (start port switch 2 monitoring process), first, it is determined whether or not the normal variation winning device 57 is in operation, that is, the open state in which the normal variation winning device 57 is activated and the game ball can be won. It is determined whether or not (step S611). In this determination, when the normal variation winning device is in operation (Yes), the process jumps to step S613 to determine whether the start port switch 2 (57b) is on. If it is determined in step S611 that the normally variable winning device is not in operation (No), it is determined in the next step whether or not the number of illegal winnings is an upper limit (step S612).

  The normally variable winning device 57 cannot win game balls in the closed state, and can win game balls only in the open state. Therefore, when a game ball wins in a closed state, it is a case where some abnormality or fraud occurs, and when there is a game ball won in such a closed state, the number is counted as an illegal winning number. ing. In step S612, it is determined whether or not the number of illegal prizes thus counted is equal to or greater than a predetermined upper limit value. In this determination, when the number of illegal winnings is the upper limit (Yes), the start port SW monitoring process is terminated. That is, in this case, the start memory is not generated. If it is determined in step S612 that the number of illegal winnings is not the upper limit (No), it is determined in step S613 whether the start port switch 2 (57b) is on.

  If it is determined in step S613 that the start port switch 2 is not on, the start port SW2 monitoring process is terminated. On the other hand, if it is determined in step S613 that the start port switch 2 is on, the process proceeds to step S614 to start the start port signal for updating the number of winning game balls to the start winning port 56 and the normal variation winning device 57. Perform output count update processing.

  Next, it is determined whether or not the starting memory number is the upper limit value (step S615). If the starting memory number is not the upper limit value (No) in this determination, the starting memory number is determined in the next step S616. After the increment (+1), the value acquired in step S55 of FIG. 26 and stored in the latch random number area in the RAM is stored in the predetermined area in the RAM (113) as the big hit random number value (step S617). Then, a predetermined loss value (fixed value) is stored in the latch random number area (step S618). Instead of storing the lost value, the stored value may be cleared to “all 0” or set to “all 1”. Thus, by storing a fixed value in the latch random number area after storing it as a random number value, even if the random number latch interrupt processing is not performed due to some trouble such as a circuit failure, the acquired counter value is duplicated. Thus, it can be prevented from being stored as a random value. As a result, when the value held in the latch random number area immediately before corresponds to the big hit, it is possible to prevent the big hit from occurring.

  Thereafter, a process of acquiring the big hit symbol random number and storing it in the RAM (step S619), and a process of acquiring the fluctuation pattern random number and storing it in the RAM (step S620). Furthermore, the process of setting the decoration special figure start memory number command to be transmitted to the effect control device 150 is set in the transmission circuit (step S621), and the start port SW monitoring process is terminated. If it is determined in step S615 that the start memory number is the upper limit value (Yes), that is, if no more start memory can be stored, the start port SW2 monitoring process is terminated.

  Further, in the starting port switch monitoring process (step S361) of FIG. 14, the starting port SW1 monitoring process (starting port switch 1 monitoring process) is executed following the above-described starting port switch 2 monitoring process. The start port switch 1 monitoring process is substantially the same as the start port switch 2 monitoring process.

  The difference between the start port switch 2 monitoring process and the start port switch 1 monitoring process is that in the start port switch 1 monitoring process, the normal variation winning device 57 in step S611 of the start port switch 2 monitoring process of FIG. 27 is operating. In step 613, the start port switch 1 (56a) is turned on instead of the start port switch 2 (57b). The point is whether or not there is a determination.

  Based on the input of the start detection signal from the outside, the value of the counter circuit 243 is latched in the latch registers 245, 247, and 249 in the random number generation circuit 124, and then the value held in the latch register in the timer interrupt processing is used as the random number value. In the case of acquisition, noise is generated in the random number generation circuit 124 between the input of the start detection signal and the start of the timer interrupt process, and the value of the counter circuit 243 is erroneously set to the latch registers 245, 247, and 249 by the noise. If the counter value is latched by any of the above, there is a possibility that the counter value taken into the latch register due to noise is acquired as a random value by the CPU.

  However, as in the above embodiment, the value held in the latch register is acquired as a random value by the random number latch interrupt process of FIG. 26 executed by the CPU based on the input of the start detection signal, and the timer interrupt process thereafter. By storing the random number value already acquired in the start port switch 2 monitoring process executed in step 2 as a regular random number value, it is latched by noise generated between the input of the start detection signal and the start of the timer interrupt process. It is possible to prevent an erroneous random number value from being used for the determination.

  FIG. 28 shows the procedure of random number latch interrupt processing in the second embodiment of the fifth invention.

  In the random number latch interrupt process of FIG. 26, the counter value acquired from the latch register is stored as a random number and added to the delay timer, whereas the random number latch interrupt process of FIG. 28 is added to the delay timer. A value and a value used as a random number are acquired from different latch registers. In applying this embodiment, when data is set in the latch register trigger circuits 244, 246 and 248, a trigger signal for latching the value of the counter circuit 243 in the corresponding latch register is generated. It is necessary that the trigger signal is also supplied to the CPU 111 to be a pseudo start winning detection signal for executing the random number latch interrupt process.

  When this random number latch interrupt process is started, interrupts are first prohibited and the values held in the various registers in the gaming microcomputer 110 are saved in the stack area in the RAM 113 (steps S61 and S62). Next, with reference to the latch permission flag corresponding to the latch register (latch 1) 247 of the status register 250, it is determined whether there is latched data (counter value) (step S63). When the random number latch interrupt processing is started for the first time, it is determined that there is no data (No), and in the next step S64, the counter value latched in the latch register (latch 0) 245 is acquired and the value is delayed. The timer is set (step S65).

  Then, the delay timer is updated (+1), and it is determined whether or not the delay timer has expired (steps S66 and S67). If the delay timer has not expired, the process returns to step S66 to update the timer. When the delay timer expires, the process proceeds to step S68 to set data in the latch register trigger circuit 246 and generate a trigger signal for causing the latch register (latch 1) 247 to latch the counter value. Thereafter, the end of the interrupt is declared and the value of the register saved in step S62 is restored to the original register, and then the interrupt is permitted and the process is terminated (steps S71 to S73).

  When the trigger signal is generated in step S68, the value of the counter circuit 243 is latched in the latch register (latch 1) 247 by the random number generation circuit 124, and the pseudo start winning detection signal is supplied to the CPU 111. Random number latch interrupt processing starts. In step S63, it is determined that there is data (Yes), the process proceeds to step S69, the counter value held by the latch register (latch 1) 247 is acquired, and the acquired value is a buffer area in the RAM. Store in the latch random number area. Thereafter, the end of the interrupt is declared and the value of the register saved in step S62 is restored to the original register, and then the interrupt is permitted and the process is terminated (steps S71 to S73).

  In this embodiment, since the counter value acquired in step S64 is different every time, it is necessary to set the value obtained by adding the acquired counter value to the value of the delay timer in the delay timer so as to exit steps S66 and S67. The time or delay time can be random. When the delay timer expires, a pseudo start winning detection signal is generated and the value of the counter circuit is latched in another latch register, which is acquired as a random number. As a result, even if it is attempted to illegally acquire the counter value of the latch register, it is difficult to specify the acquisition timing, and illegal activities can be prevented.

  FIG. 28 is a flowchart when the start winning detection signal DET0 is input and the hard latch signal LAT0 for latching the value of the counter circuit 243 in the latch register (latch 0) 245 is generated based on the start winning detection signal DET0. When the start winning detection signal DET1 is input, “Latch 1” in Steps S63, S68, and S69 of FIG. 28 is replaced with “Latch 0”, and “Latch 0” in Step S64 is replaced with “Latch 1”. This can be dealt with by performing processing according to a similar flowchart.

  Although the invention made by the present inventor has been specifically described based on the embodiments, the embodiments disclosed herein are illustrative and non-restrictive in every respect. The scope of the present invention is shown not by the above description of the invention but by the scope of claims, and is intended to include all modifications within the scope and meaning equivalent to the scope of claims.

  For example, in the embodiment, the latch permission flag is provided in the status register 250 to control the latching of the counter value to the latch register. However, when the latch signal is input, the counter value is transferred to the destination. When the value is “0000h”, the counter value is stored in the register. When the register value is not “0000h”, the counter value is not stored in the register. By doing so, the latch register may be prevented from being overwritten. In this way, the status register can be omitted.

  Further, by providing a flag indicating prohibition / permission of latch in the status register, the value of the counter circuit can be prevented in the latch register at an incorrect timing due to noise. Therefore, the software processing shown in FIGS. 20 and 21 is applied. In this case, the random number generation circuit 124 may omit the prevention of erroneous latching of the counter value by hardware using the latch permission flag of the status register 250. However, it is possible to realize a gaming microcomputer that is more resistant to noise by applying both prevention of erroneous latching of the counter value by hardware and prevention of erroneous latching of the counter value by software.

  The present invention is not limited to a pachinko gaming machine in which a game ball as a game medium is rented out by a card unit, and can also be applied to a gaming machine such as an arrangement ball gaming machine, a sparrow ball gaming machine, and a slot machine.
