The timer interrupt processing includes: winning determining steps (S125 and S128) for determining winning based on a received winning ball detection signal; a put-out control management step of generating a winning ball specifying command according to the result of winning determination; and an output step of transmitting the generated winning ball specifying command to a put-out control device. The main control CPU interrupts the main routine preferentially with main interrupt processing over the power shut-off time evacuation processing. Interrupt by the main interrupt processing is prohibited while the power shut-off time evacuation processing is executed, and the winning determining steps are not executed if the power shut-off is detected (S124:Yes, S127:Yes) before execution of the winning determining steps in the main interrupt processing.

Description

  The present invention relates to a ball game machine.

  In Patent Document 1, an interrupt is generated when a power-off signal is received, data necessary for recovery of the control state is saved in the interrupt process, and the storage destination address of the saved data is stored. A gaming machine that executes a data saving process is described.

  Patent Document 2 describes a gaming machine that executes a power interruption detection process based on a power interruption detection signal by polling after prohibiting the occurrence of a timer interrupt in the main routine.

Japanese Patent No. 3768419 Japanese Unexamined Patent Publication No. 2007-50109

  In Patent Document 1, since the interruption of the power-off signal is generated immediately, the amount of data to be saved is increased and the restoration program is complicated. On the other hand, in Patent Document 2, since the power interruption detection signal is monitored by polling, the processing load increases as compared with the interrupt processing.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to suppress the amount of data to be saved when the power is cut off, to avoid complication of the restoration program, and to reduce the processing load.

  To achieve the above object, the ball game machine according to the present invention includes a main control device that controls execution of game processing, and a winning ball detection signal for the main control device that detects a winning of a game ball that has been launched into the gaming area. And a payout control device for controlling the payout of the game ball, and operates by receiving power supply from the power supply device.

  The main control device includes power-off detection means and execution control means. The power-off detection unit detects the occurrence of power-off. The execution control means includes a predetermined main routine that starts when the power supply device is turned on, a main interrupt process (timer interrupt process) that starts every predetermined time and interrupts the main routine, and a power-off detection means that detects power-off. Controls the execution of the power-off saving process that starts and interrupts the main routine.

  The main interruption process generates a payout command transmission signal corresponding to the determination result in the winning determination process and the winning determination process for determining whether or not the game ball has won based on the winning ball detection signal received from the winning detection means A payout control management process, and an output process for sending the payout command transmission signal generated in the payout control management process to the payout control device.

  The execution control means interrupts the main interrupt process into the main routine in preference to the save process when the power is cut off, prohibits the interrupt of the main interrupt process during the save process when the power is cut off, and executes the main interrupt process during the execution of the main interrupt process. If the power-off detection means detects a power-off before executing the winning determination process, the winning determination process is not executed.

  The gaming machine may include a power-off signal generating unit that generates a power-off signal when a power-off occurs. It may be detected that has occurred. Further, the power-off signal generating means may transmit the generated power-off signal to the main control device, and the power-off detecting means generates a power-off when receiving the power-off signal from the power-off signal generating means. May be detected.

  In the above configuration, the main interrupt process interrupts the main routine in preference to the power-off save process, so even if a power interruption occurs during execution of the main interrupt process, the main interrupt process is saved when the power is cut off. Without being interrupted by the processing, the power-off saving processing is started after the end of the main interrupt processing. Therefore, it is possible to minimize the amount of data to be saved in the saving process when the power is turned off, and to avoid the complicated return program.

  Moreover, since the power-off signal is not monitored by polling, the processing load can be reduced.

  Furthermore, in the main interrupt process, if the power interruption detection means detects the power interruption before the winning determination process is executed, the winning determination process is not executed. Even if input is made to the main control device, payout based on erroneous input is not performed. Therefore, for example, even when the player intentionally turns off the power to illegally acquire a prize ball, the prize ball is not paid out and the illegal acquisition of the prize ball is prevented. be able to.

  The main interrupt process may include a jackpot determination process in which an electronic winning / notifying lottery for determining whether or not to generate a jackpot gaming state is executed according to a determination result in the winning determination process.

  In the above configuration, since the winning lottery is not executed due to erroneous input of the winning ball detection signal due to noise or the like due to power cut-off, illegal generation of the big hit gaming state can be prevented.

  According to the present invention, it is possible to suppress the amount of data to be saved when the power is turned off, to avoid complication of the restoration program, and to reduce the processing load.

  The prize ball case is provided with a payout motor (for example, a stepping motor) 83, and the payout control device 71 (payout control board unit 63) is provided with a drive circuit (not shown) of the payout motor 83. The payout control device 71 rotationally drives the payout motor 83 based on the prize ball instruction command received from the main control CPU 73, and pays out the designated number of game balls from the prize ball case. The game balls that have been paid out flow down to the front board 4 through a payout passage (not shown).

  A payout counting switch 84 is installed on the downstream side of the payout motor 83, and when a prize ball is actually paid out by driving the payout motor 83, a count signal from the payout count switch 84 is transmitted to the payout control device 71. The payout control CPU 80 detects the actual payout number and the out-of-ball state based on the received count signal, and manages the payout of game balls.

  A tray full tank switch 85 is installed in the supply path of game balls to the upper plate 10 (shown in FIG. 1), and when the lower plate 11 (shown in FIG. 1) is full of game balls, the plate full tank switch 85 is turned on. It becomes ON, and a full tank detection signal is transmitted to the payout control device 71. The payout control CPU 80 that has received the full tank detection signal temporarily holds the prize ball operation according to the prize ball instruction command received from the main control CPU 73, and stores the unpaid prize ball remaining number in the RAM 82. The RAM 82 can be backed up even when the power is cut off, so that even if a power outage (including momentary power outage) occurs during the game, the information on the number of remaining unpaid prize balls will not be lost. .

  The firing device 19 (shown in FIG. 2) is provided with a firing motor 86 and a ball feed solenoid 87, and the firing handle 18 (shown in FIG. 1) has a firing volume 88, a touch sensor 89, a firing stop switch 90, Is provided. The ball feed solenoid 87 sends game balls that have flowed down from the upper plate 10 (shown in FIG. 1) one by one to the launch position, and the launch motor 86 launches the game balls sent to the launch position. In addition, the launch interval of game balls is, for example, about 0.6 seconds (within 100 per minute).

  The firing volume 88 transmits a firing force instruction signal proportional to the rotational operation amount (stroke) of the firing handle 18 (shown in FIG. 1) to the dispensing control device 71. The touch sensor 89 detects that the player's body is touching the firing handle 18 from the change in capacitance, and transmits the detection signal to the payout control device 71. The firing stop switch 90 transmits a firing stop signal (contact signal) to the payout control device 71 when operated by the player.

  When the player rotates the firing handle 18, a firing force instruction signal corresponding to the amount of rotational operation is transmitted from the firing volume 88 to the payout control device 71. The payout control CPU 80 controls driving of the firing motor 86 based on the received firing force instruction signal. Thereby, the launch strength of the game ball is adjusted according to the operation amount of the player. However, the payout control CPU 80 stops driving the firing motor 86 when the detection signal from the touch sensor 89 is off (low level) and when the firing stop signal is input from the firing stop switch 90. In addition, the payout control CPU 80 stops the driving of the firing motor 86 when the CR unit 50 is not connected to the pachinko machine P.

  When the ball lending switch 12 or the return switch 13 is operated, the operation signal is transmitted to the CR unit 50 via the relay board 91. From the CR unit 50, a frequency signal indicating the remaining frequency of the valuable medium is transmitted to the frequency display device 14 via the relay substrate 91.

(Sub-control device 72)
The sub-control device 72 is equipped with a circuit board (composite sub-control board) on which an effect control CPU 92 is mounted. The effect control CPU 92 also includes a CPU core (not shown), like the main control CPU 73, and includes a ROM 93, The semiconductor memory such as the RAM 94 is configured as an LSI. The sub-control device 72 is equipped with an input / output driver and various peripheral ICs (both not shown).

  The ROM 93 of the sub-control device 72 stores an effect control program related to effect control, and the effect control CPU 92 follows an effect command transmitted from the main control CPU 73 in accordance with the stored effect control program. The effect control by the effect display device 31, the various lamps 25 and 60, the sound generator 97 and the movable accessory is executed. The effect display device 31 includes an image processor, a liquid crystal, and the like, and the sound generation device 97 includes a sound processor, a speaker 22, and the like. The production control includes image display control of the production display device 31, light emission control of the various lamps 25 and 60, sound generation control from the speaker 22, and drive control of the movable accessory drive device 95. Note that the image processor and the sound processor may be provided in the sub-control board unit 64.

(Output to the outside)
Various external information signals generated in the main control device 70 and the payout control device 71 are output from the external information terminal board 65 to the outside. The signals output from the external information terminal board 65 are totaled, for example, by a hall computer 68 in a game hall.

[Description of input port of main controller 70]
A plurality of input / output ports (including three input ports of input port 0, input port 1, and input port 2 in this embodiment) are set in the input / output ports of main controller 70. The input port 0 includes a switch abnormality signal (a disconnection signal of the detection sensors 55 to 59 mounted on the game board 5), a door opening signal (contact signals from the door opening switches 78 and 79), and an error detection signal (error detection sensor 98). ), A payout command permission signal (a signal from the payout control device 71), and an RWM clear signal (a signal from the power supply device 61). A winning ball detection signal from the big winning ball detection sensor 58 and the general winning ball detection sensor 59 is assigned to the input port 1. The input port 2 has a winning ball detection signal from the first special figure starting ball detection sensor 56, a winning ball detection signal from the second special figure starting ball detection sensor 57, and a ball passage detection signal from the gate passing ball detection sensor 55. , And a power-off notice signal from the power supply device 61 is assigned. Each input port is provided with a 1-bit reception storage area whose state is switched at the time of reception of each signal (switched at 1/0), and input confirmation of each signal is performed by bit check of the corresponding reception storage area. . The input port 2 functions as a power-off signal receiving unit that receives a power-off notice signal when a power-off occurs, and the state of the corresponding reception storage area is switched while the power-off notice signal is input to the input port 2. .

[Control processing executed by main controller 70]
Next, the control process executed by the main control CPU 73 of the main control device 70 according to the game control program stored in the ROM 74 will be described. The control processing executed by the main control CPU 73 includes CPU initialization processing as a main routine, main loop, serial communication reception interrupt processing, timer interrupt processing (main interrupt processing), and power-off saving processing. Control the execution of these processes.

  As shown in FIG. 6A, the interrupt generation factor of the serial communication reception interrupt process is established by reception of the main command, and the occurrence factor of the timer interrupt process is established every predetermined period (4 ms in this embodiment). The cause of the interruption of the saving process when the power is cut off is established by the occurrence of the INT interruption due to the reception of the power cut notice signal. The serial communication reception interrupt process, the timer interrupt process, and the power-off save process are set so that the interrupt priority becomes higher in this order. The serial communication reception interrupt process and the power-off save process prohibit multiple interrupts, and the timer interrupt process allows multiple interrupts.

  That is, in the main controller 70, as shown in FIG. 6B, the main routine is repeatedly executed as the basic process, and the timer interrupt process is activated at predetermined intervals to interrupt the main loop. When a main command is received during execution of the main routine or timer interrupt processing, serial communication reception interrupt processing is activated and interrupts the main loop or timer interrupt processing (not shown). If a power-off notice signal is received during execution of the main routine (serial communication reception interrupt processing and timer interrupt processing are not being executed and the main command has not been received), the power-off save processing is activated and the main routine is entered. interrupt. Further, when the power interruption notice signal is received during the execution of the timer interruption process, the power interruption interruption process is started after the timer interruption process is completed and the process returns to the main loop. However, the serial communication reception interrupt processing and main interrupt processing are not activated during the power-off save process, and if an interrupt factor is established during the power-off save process, the power-off save process is performed. The corresponding interrupt processing is started after waiting for the end of. Note that the interrupt process is started on condition that the interrupt destination process (the process currently being executed) is in the interrupt enabled state.

  In addition, the main interrupt process is a process of acquiring and storing the contents of the input port 1 and the input port 2 (steps S123 and S126 in FIG. 12) and whether the game ball has won based on the information acquired by the port input process. A winning determination process (a process for generating an on-edge detection flag for the input port 1 (step S125 in FIG. 12), a process for generating an on-edge detection flag for the input port 2 (step S128 in FIG. 12)), and a jackpot A jackpot determination process (switch management process in FIG. 11 (step S69) and a special game management process) in which an electronic winning lottery for determining whether or not to generate a gaming state is executed according to the determination result in the winning determination process (Step S70)) and a payout control management process (FIG. 11) for generating a payout command transmission signal according to the determination result in the winning determination process Step including S74 as), the output process of transmitting a payout command transmit signal produced at the payout control management process to the payout controller 71 (step S79 in FIG. 11). While the main CPU 73 prohibits interruption of the power-off saving process during execution of the timer interruption process, the main CPU 73 receives a power-off notice signal before executing the winning determination process in the timer interruption process being executed (step in FIG. 12). In S124: Yes, step S127: Yes, the winning determination process is not executed.

(CPU initialization process)
When power is turned on to the pachinko machine P, the main control CPU 73 starts a CPU initialization process. A stable game operation of the pachinko machine P is guaranteed by the CPU initialization process.

  7 and 8 are flowcharts showing a CPU initialization process executed by the main control CPU 73.

  When the CPU initialization process is started, the top address (address initial value) of the stack area is set in the stack pointer (step S1), and the vector type interrupt mode (interrupt mode mode 2) is set (step S2). As a result, the main control CPU 73 can refer to an arbitrary address (however, the least significant bit is 0) as an interrupt vector and execute a specified interrupt handler.

  Next, an interrupt vector table is set (step S3), a built-in register is set (step S4), the contents of the input port 0 are read twice (step S5), the result of the input port 0 is logically converted, and the RAM 75 Retreat to the retreat area (step S6).

  Next, a reset standby process is executed. In this process, a certain waiting time (for example, about several thousand ms) is secured at the start of reset (for example, power-on), and the power-off notice signal for the input port 2 is checked during that time. In this embodiment, a loop counter for 2 seconds is set as waiting for the start of sub-control (step S7), and the input port of the power-off notice signal is bit-checked while decrementing the value of the loop counter (step S8). If a power-off notice signal is input before 2 seconds elapse (before the loop counter reaches 0) (step S9: Yes), the process returns to the beginning of the reset standby process (step S7). This process is continued until two seconds elapse without inputting the power-off notice signal (Step S9: Yes → Step S7, or Step S9: No → Step S10: No → Step S8), and the power-off notice signal is inputted. If 2 seconds elapse without (step S9: No-> step S10: Yes), this process is terminated. Thereby, for example, transmission of a control signal from the main control device 70 to the sub control device 72 before the start of the start processing of the sub control device 72 can be prevented. Further, it is possible to protect the system when the operation of turning on and off the main power switch (not shown) is repeatedly performed within a short time (about 1 to 2 seconds).

  Next, access to the work area of the RAM 75 is permitted (step S11). Specifically, the RAM protect setting value in the work area is reset. As a result, the access to the work area of the RAM 75 is permitted thereafter.

  Next, the result of the input port 0 saved in step S6 is restored (step S12), the RWM clear signal of the restored input port 0 is referred to, and the bit of the RWM clear signal is turned on (RWM clear switch 69). Is determined) (step S13).

  When the RWM clear switch 69 is not operated (step S13: No), it is determined whether or not the backup validity determination value (backup validity determination flag) is stored in the RAM 75. Specifically, the data in the backup judgment storage area of the RAM 75 is compared with the backup validity judgment value (step S14), and if they match (when the backup validity judgment flag is set), the power is turned off. It is determined that it is a CPU initialization process after the time saving process has been properly completed (step S15: No), and when there is a mismatch (when the backup validity determination flag is not set), the saving process at the time of power-off is performed. It is determined that the CPU initialization process is not properly completed (step S15: Yes).

  If it is a CPU initialization process after the power-off saving process is properly completed (step S15: No), a sum check is performed on the backup information in the RAM 75. Specifically, the checksum value is calculated for the work area of the RAM 75 (the user work area including the use prohibition area and the stack area) excluding the backup determination storage area and the sum check buffer (step S16). It is determined whether or not the checksum value is a normal value (step S17). Specifically, the checksum value calculated in step S16 is compared with the checksum value saved in the power-off saving process (step S108), which will be described later, and if they match, it is determined to be a normal value. If they are different, it is determined that the values are not normal.

  If the checksum value is a normal value (step S17: Yes), a return process (step S18 to step S20) is executed.

  In the return process, after resetting the power return clear area (for example, the backup determination storage area) (step S18), the effect control return process (step S19) and the payout control return process (step S20) are executed.

  In the effect control return process (step S19), the sub-control device 72 is instructed to return to the sub-control device 72 (for example, model designation command, special symbol probability state designation command, working memory number command, number-of-times counter remaining command, special game) Send a status specification command. Receiving this, the sub control device 72 performs the effect state (for example, internal probability state, effect symbol display mode, working memory count effect display mode, sound output content, various lamps, etc. that were being executed at the previous power-off. Light emission state).

  In the payout control return process (step S20), a payout command for power supply return is transmitted to the payout control device 71. Receiving this, the payout control device 71 restores the previous power-off state and cancels the payout prohibition state.

  On the other hand, if the RWM clear switch 69 has been operated (step S13: Yes), if it is not a CPU initialization process after the power-off saving process is properly completed (step S15: Yes), or the checksum value is If it is not a normal value (step S16: No), an initialization process (steps S21 to S24) is executed.

  In the initialization process, all storage areas other than the use-prohibited area of the RAM 75 are cleared (step S21). As a result, the work area and stack area of the RAM 75 are all initialized.

  Next, the RAM 75 is initialized by setting an initial value at the time of clear activation in the RAM 75 (step S22), and an effect control initialization process (step S23) and a payout control initialization process (step S24) are executed.

  In the effect control initialization process (step S23), a subcommand for RWM clear designation is transmitted to the sub-control device 72. Receiving this, the sub-control device 72 initializes the effect control state. In the payout control initialization process (step S24), a payout command for RWM clear is transmitted to the payout control device 71. Receiving this, the payout control device 71 initializes the payout control state and cancels the payout prohibition state.

  When the payout control return process (step S20) or the payout control initialization process (step S24) ends, the subcommand after power-on is transmitted to the effect control device 73 (step S25), and the contents of the input port 1 are acquired. (Step S26) The contents of the input port 2 are acquired (Step S27), the random number latch register is cleared (Step S28), the main command permission signal is set (Step S29), and the timer interrupt counter is set (Step S29). In step S30, the interrupt daisy chain is reset (step S31), and the process proceeds to the main loop. By resetting the interrupt daisy chain (step S31), when the determination of step S113 (see FIG. 13) in the power-off saving process, which will be described later, shifts to the CPU initialization process in Yes, the RETI when exiting from the interrupt process Since the processing is not performed, even if the interrupt is permitted in step S45 (see FIG. 9) in the main loop to be described later, it is prevented that the processing does not shift to each interrupt processing.

(Main loop)
FIG. 9 is a flowchart showing a main loop executed by the main control CPU 73.

  In the main loop, after interrupts are prohibited (step S41), initial value random number update processing (step S42), main command analysis processing (step S43), subcommand transmission processing (step S44) are executed, and interrupts are permitted. (Step S45), Other random number update processing (Step S46) is executed, and the process returns to Step S41. Therefore, a period during which interruption of the power-off saving process is allowed for the main loop is during the execution of the other random number update process (step S46).

  In the initial value random number update process (step S42), the initial value update random number for winning symbol random numbers is updated. The initial value update random number for the winning symbol random number is a software random number for determining the initial value and the end value of the winning symbol random number. The winning symbol random number is a software random number used for the lottery of the winning type. Note that the reason why step S42 is executed in a state where interrupts are prohibited (step S41) is the same as the timer interrupt process (step S67 in FIG. 11), and therefore overlap (conflict) with this is prevented. Because. In addition, the winning determination random number (normal winning winning random number) and the big winning determining random number (special winning winning random number) of the present embodiment are hardware random numbers generated by the hard random number generation circuit 76, and the update cycle thereof is a timer. Since it is faster (for example, several μs) than the interrupt cycle (for example, several ms), it is not necessary to update the initial value of the jackpot decision random number.

  The main command analysis process (step S43) is a process for analyzing commands received from the payout control device 71 (including payout commands for specifying various error occurrences and payout commands for specifying error cancellation). In the subcommand transmission process (step S44), a subcommand (a subcommand necessary for presentation control) to be transmitted after the initial setting is transmitted to the presentation control device 72. In other random number update processing (step S46), for example, reach group determination random numbers, reach mode determination random numbers, fluctuation pattern random numbers, and the like are updated. The reach group decision random number is a software random number used for the lottery of the special symbol variation pattern reach group, and the reach mode decision random number is a software random number used for the lottery of the special symbol variation pattern reach mode. Is a software random number used for drawing a special symbol variation pattern.

(Serial communication reception interrupt processing)
FIG. 10 is a flowchart showing serial communication reception interrupt processing executed by the main control CPU 73. When the main control CPU 73 receives a main command (for example, various payout commands input from the payout control device 71) while interrupting the main loop or permitting interrupt of the timer interrupt process, the main control CPU 73 gives priority to the received main command. Interrupt the serial communication reception interrupt process to process.

  As shown in FIG. 10, in the serial communication reception interrupt process, the value of the AF register is saved in the save area of the RAM 75 (step S51), and the contents of the status register of channel A (CHA) are loaded (step S52). It is checked whether or not there is data in the FIFO (step S53), the received value is obtained from the CHA data register (step S55), and it is determined whether or not there is data in the reception FIFO (step S55). If there is no data (step S55: Yes), the value of the AF register saved in step S51 is restored (step 57), the interrupt is permitted (step S58), and the serial communication reception interrupt process is terminated. On the other hand, if there is data in the reception FIFO (step S55: No), the reception data is stored in the main command buffer (step S56), the value of the AF register saved in step S51 is restored (step 57), and an interrupt is issued. After permitting (step S58), the serial communication reception interrupt process is terminated. Upon completion of the serial communication reception interrupt process, the process returns to the main loop (program address indicated by the stack pointer).

(Timer interrupt processing)
FIG. 11 is a flowchart showing timer interrupt processing executed by the main control CPU 73. In the main control CPU 73, the counter / timer circuit generates an interrupt request signal every predetermined period, and based on the generation of the interrupt request signal, interrupts the timer interrupt processing in the main loop that is permitted to interrupt.

  As shown in FIG. 11, in the timer interrupt process, all register values used during execution of the main loop are saved in the save area of the RAM 75 (step S61). Another value can be written into the register after saving the value during the timer interrupt processing.

  Next, the interrupt flag is initialized (step S62), the interrupt is permitted (step S63), the dynamic port output process is executed (step S64), and the boat input process is executed (step S65).

  In the port input process (step S65), as shown in FIG. 12, the on-edge detection flag is cleared (step S121), the contents of the input port 0 are acquired and stored (step S122), and the contents of the input port 1 are acquired and stored. After saving (step S123), it is determined whether or not a power-off notice signal is received (step S124). Specifically, the input port of the power-off notice signal is bit-checked to determine whether or not the power-off notice signal is input.

  When the power-off notice signal is not received (step S124: No), the on-edge detection flag of the input port 1 is generated (step 125), and when the power-off notice signal is received (step S124: Yes). In this case, the on-edge detection flag for the input port 1 is not generated. The detection of the winning of the game ball to the big winning opening 52 and the general winning opening 37 is performed by changing the reception storage area (1 bit) corresponding to the big winning ball detecting sensor 58 and the general winning ball detecting sensor 59 to the reception state. For example, when the reception storage area corresponding to the general winning ball detection sensor 59 has been switched to the reception state, the corresponding on-edge detection flag must be received as a power-off notice signal. If the power-off notice signal is received, it is not set to ON and is kept off.

  Next, as with the input port 1, after acquiring and saving the contents of the input port 2 (step S126), it is determined whether or not a power-off notice signal has been received (step S127).

  When the power-off notice signal has not been received (step S127: No), the on-edge detection flag of the input port 2 is generated (step 128), this processing is terminated, and the power-off notice signal is received. In the case (step S127: Yes), this process ends without generating the on-edge detection flag of the input port 2. Receiving storage areas corresponding to the first special figure start ball detection sensor 56 and the second special figure start ball detection sensor 57, respectively, for detecting the winning of the game ball to the first start winning opening 35 and the second start winning opening 36. For example, when the reception storage area corresponding to the second special figure starting ball detection sensor 57 is switched to the reception state, the corresponding on-edge is detected. The detection flag is set to ON if the power-off notice signal is not received, and is kept off without being set to ON if the power-off notice signal is received. The detection of the passage of the game ball to the through chucker 32 is performed by detecting the change (rise) of the reception storage area (1 bit) corresponding to the gate passing ball detection sensor 55 to the reception state. If the reception storage area corresponding to the ball detection sensor 55 has been switched to the reception state, the corresponding on-edge detection flag is set to ON if the power-off notice signal has not been received, and the power-off notice signal has been received. Keep it off without setting it on.

  Thus, in the port input process, the passage detection signal from the gate passage ball detection sensor 55, the first special figure start ball detection sensor 56, the second special figure start ball detection sensor 57, the big winning ball detection sensor 58, and The input state (ON / OFF) of the winning detection signal from the general winning ball detection sensor 59 is read. If it is not when the power is cut off, it detects the passing or winning of the game ball by detecting the change of the receiving storage area to the receiving state, and if the passing or winning is detected, the corresponding on-edge detection flag is set to ON. Then, this process is terminated. On the other hand, when the power is cut off, the process is terminated without detecting the passing of a game ball or winning. When this process ends, the timer update process (step S66) and the initial value random number update process (step S67) in FIG. 11 are executed.

  In the timer update process (step S66), the count value of the counter / timer circuit is updated to the initial value, and the cycle count is restarted. In the initial value random number update process (step S67), the same process as the initial value random number update process (step S42 in FIG. 9) of the main loop is executed.

  Next, a winning symbol random number update process is executed (step S68). In the winning symbol random number update process, the value of the counter for generating the winning symbol random number for jackpot symbol lottery is updated. The counter value is incremented in the counter area of the RAM 75 and loops within a specified range.

  Next, switch management processing is executed (step S69). In the switch management process, a game ball won in the first start winning opening 35 detected in the port input process (step S65), a game ball win in the second start winning opening 36, and a game ball in the through chucker 32 is obtained. The hard random number used for each success / failure determination process is acquired based on the passage of.

  Specifically, when the winning of the game ball to the first start winning opening 35 is detected (when the corresponding on-edge flag is on), the first special figure reserved random number storage area stored in the RAM 75 is stored. It is determined whether or not the number of one special figure reserved random number is less than the upper limit number (4). If the number does not reach the upper limit number, a determined random number per first special figure is obtained and used as the first special figure reserved random number. Store in the first special figure reserved random number storage area. On the other hand, when the number of first special figure reservation random numbers has reached the upper limit, the determined random number per first special figure is not acquired.

  Similarly, when the winning of the game ball to the second start winning opening 36 is detected (when the corresponding on-edge flag is on), the second special figure stored in the second special figure holding random number storage area of the RAM 75 is detected. It is determined whether or not the number of figure-holding random numbers is less than the upper limit number (4). If the number does not reach the upper-limit number, a determined random number per second special figure is obtained and the second special figure holding random number is second. Store in the special figure holding random number storage area. On the other hand, when the number of second special figure reservation random numbers has reached the upper limit number, the determined random number per second special figure is not acquired.

  When the passage of the game ball to the through chucker 32 is detected (when the corresponding on-edge flag is turned on), the number of general-purpose reserved random numbers stored in the general-purpose reserved random number storage area of the RAM 75 is the upper limit number (4 If the maximum number is not reached, a determined random number per map is acquired and stored as a general reserved random number in the general reserved random number storage area. On the other hand, when the number of ordinary-pending random numbers has reached the upper limit, no determined random number is acquired per ordinary figure.

  In addition, when acquiring a determined random number per first special figure or a determined random number per second special figure, a soft random number used as a design display random number is acquired. The symbol display random number is made up of a plurality of independent random numbers (per symbol random number, reach group determination random number, reach mode determination random number, and variation pattern random number). 4) is stored in the RAM 75. Even when the passing of the game ball to the through chucker 32 is detected (in the case of a normal symbol), the symbol display random number is acquired and stored in the same manner as in the case of the special symbol. Compared to the simplified.

  In this way, the random number determined per first special figure or the random number determined per second special figure and the corresponding random number for symbol display (per random symbol random number, reach group determined random number, reach mode determined random number, and variation pattern random number) are acquired. The timing is when a game ball is won in the first start winning opening 35 or the second start winning opening 36 (when the game ball is detected by the first special figure start detection sensor 56 or the second special figure start detection sensor 56). Yes, the timing for acquiring the determined random number per symbol and the corresponding symbol display random number is when the game ball passes through the through chucker 32 (when the game ball is detected by the gate passing ball detection sensor 55).

  Next, special game management processing is executed (step S70). In the special game management process, the internal lottery (special symbol determination process) related to the first special symbol or the second special symbol, and the display mode of symbol variation and stop by the first special symbol display device 40 and the second special symbol display device 41 (Design and variation pattern determination process) is executed.

  In the special symbol determination process, the first special figure reservation random number stored first in the first special figure reservation random number storage area or the second special figure reservation random number stored first in the second special figure reservation random number storage area The first special figure success / failure determination table is set in advance as to whether or not the read special figure holding random number (the determined random number per first special figure or the determined random number per second special figure) is a win. Alternatively, it is determined with reference to the second special figure determination table (special drawing lottery). The first special figure reserved random number is erased from the first special figure reserved random number storage area by being read out as a determined random number per first special figure, and the second special figure reserved random number is read out as a determined random number per second special figure. As a result, it is erased from the second special figure reservation random number storage area. When both the first special figure reservation random number and the second special figure reservation random number are stored, the second special figure reservation random number may be preferentially read and the storage area (the first special figure or the second special figure may be stored). Regardless of whether or not it is a special figure, the stored ball random number stored first may be read.

  In the symbol and variation pattern determination process, the special symbol stop symbol and variation pattern (variation pattern command) correspond to the read random number determined per the first special symbol or the determined random number per second special symbol and the random number for determination per collision. The variation pattern determined by referring to a preset pattern determination table according to the combination of the winning symbol random number, reach group determination random number, reach mode determination random number, and variation pattern random number stored first. Store the command in the port output request buffer. The winning symbol random number defines the stop symbol of the special symbol, and also defines the mode (type) of the jackpot gaming state that occurs when the special symbol lottery is won. The variation pattern defines a variation time, presence / absence of reach, basic production pattern at the time of reach, and the like.

  When the special drawing lottery is won, a big hit gaming state of a mode corresponding to the winning symbol random number is generated. For example, per 2R normal per, 2R normal per change, 15R normal per, 15R per normal change, etc. are set, and the attack device 39 is opened and closed by 2 rounds per 2R, and the attack device 39 is opened per 15R. Open and close for 15 rounds. Further, in the normal hit, the game may be shifted to the normal game state or the short-time game state after the jackpot game is ended (the operation of the attacker device 39 is ended), and in the probability change, the game may be shifted to the probability change game state after the jackpot game is ended.

  In the probability variation gaming state, the success / failure determination table to be referred to in the special symbol determination process is changed from the normal low probability determination table to the high probability determination table (determination table having a higher winning probability than that for normal use). The probable gaming state continues until the next special figure winning, but the short-time gaming state is ended by executing the special drawing lottery a predetermined number of times.

  Also, in the special game management process, the start and end of the fluctuation of the first special symbol and the second special symbol, the start and end of the jackpot gaming state, the number of rounds in the jackpot gaming state, the start and end of the probability variation gaming state, the short-time gaming state Management related to such management (for example, change start instruction command indicating the start of special symbol change, change end instruction command indicating end, etc.) is stored in the port output request buffer. .

  Next, a normal game management process is executed (step S71). In the normal game management process, internal lottery (normal symbol determination process) corresponding to a normal symbol, determination of a display variation and stop display mode (symbol and variation pattern determination process) by the general symbol display device 42, and the like are executed.

  In the normal symbol determination process, the normal figure hold random number stored first in the normal figure hold random number storage area is read, and whether or not the read general figure hold random number (determined random number per common figure) is winning is set in advance The decision is made with reference to the ordinary figure determination table (normal drawing lottery). The general-purpose reserved random number is erased from the general-purpose reserved random number storage area by being read as a determined random number per general-purpose figure.

  In the symbol and variation pattern determination processing, the symbol stop symbol and variation pattern (variation pattern command) are displayed for the symbol display stored in the earliest correspondence with the read random number for each universal symbol and the random number for determining the symbol. It is determined by referring to a preset pattern determination table according to the combination of random numbers.

  In addition, when the normal symbol lottery is won in the normal symbol determination process, the electric tulip 33 is opened a predetermined number of times (in this embodiment, once). Also, in the probability variation gaming state and the short-time gaming state, the normal symbol determination table to be referred to in the normal symbol determination process is changed from the normal low probability determination table to the high probability determination table (determination table having a higher winning probability than the normal one). The pattern determination table that is changed and referred to in the symbol and variation pattern determination processing is changed from the normal pattern determination table to the time reduction pattern determination table (determination table having a shorter variation time than normal).

  Next, error management processing is executed (step S72). In the error management process, if the input of the error detection signal of the input port 0 saved in the port input process (step S122) is confirmed, there is a possibility that fraud using a magnet or the like has been performed. The predetermined error process is executed without executing the process.

  Next, a winning opening switch process is executed (step S73). In the winning opening switch processing, the winning information of the game balls to the first starting winning opening 35, the second starting winning opening 36, the general winning opening 37, and the big winning opening 52 detected in the port input process (step S65) (each ON information of on-edge flag) is acquired.

  Next, a payout control management process is executed (step S74). In the payout control management process, a prize ball instruction command for instructing the payout control device 71 to execute a prize ball operation and the number of prize balls is generated based on the prize information acquired in the prize opening switch process (step S73), and the port Store in the output request buffer.

  Next, external information processing is executed (step S75). In external information processing, an external information signal (for example, prize ball information, door opening information, symbol determination number information, jackpot information, start opening information, etc.) output to the hall computer 68 of the game hall via the external information terminal board 65 is ported. Store in the output request buffer.

  Next, a test signal management process is executed (step S76). In the test signal management process, the main control CPU 73 has various test signals representing its own internal state (for example, normal symbol game management state, special symbol game management state, jackpot, probability variation function in operation, time reduction function in operation). Are stored in the port output request buffer. With this test signal, for example, the internal state of the main control CPU 73 can be tested outside the main controller 70.

  Next, an LED display setting process is executed (step S77). In the LED display setting process, byte data applied to each LED in order to control the lighting state of the first special figure display device 40, the second special figure display device 41, the universal figure display device 42, the state display device 43, etc. Is stored in the port output request buffer.

  For example, for the first special figure display device 40 and the second special figure display device 41, a drive signal for performing lighting display with the special figure stop symbol and the variation pattern determined in the special game management process (step S70). Stored in the ordinary figure display device 42 is stored a driving signal for performing the illumination display with the ordinary figure stop symbol and the variation pattern determined in the normal game management process (step S71). For the display unit 46, a drive signal for performing lighting display indicating the number of second special figure reservation random numbers stored in the second special figure reservation random number storage area is stored. Then, a drive signal for performing a lighting display indicating the number of the general-purpose reserved random numbers stored in the general-purpose reserved random number storage area is stored, and for the round number display section 44, a special game management process (step S70). Managed in Storing a drive signal for causing the lighting display that indicates the current number of rounds in the bonus game to have.

  Next, solenoid output image composition processing is executed (step S78). In the solenoid output image composition processing, a drive signal as a control command output to the attacker drive device 54 and the electric tulip drive device 51 for opening / closing control of the attacker device 39 and the electric tulip 33 is stored in the port output request buffer. .

  For example, for the attacker drive device 54, a drive signal for opening and closing the attacker device 39 based on the round during the jackpot game managed in the special game management process (step S70) is stored, and the electric tulip drive device 51 is stored. On the other hand, a drive signal for opening the electric tulip 33 a predetermined number of times in accordance with the winning of the general drawing lottery in the normal game management process (step S71) is stored.

  Next, a port output process is executed (step S79). In the port output process, each signal stored in the port output request buffer in each process described above (step S70, step S74 to step S78) is output to the corresponding transmission target.

  For example, the variation pattern command and the effect related command stored in the special game management process (step S70) are transmitted to the sub-control device 72, and the prize ball instruction command stored in the payout control management process (step S74) is sent out. 71, the external information signal stored in the external information processing (step S75) is transmitted to the external information terminal board 65, and the drive signal stored in the LED display setting process (step S77) is transmitted to each of the display devices 40 to 43. And the drive signal stored in the solenoid output image composition process (step S78) is transmitted to the attacker drive device 54 and the electric tulip drive device 51.

  Finally, the values of all registers saved in step S61 are restored (step S80), and the timer interrupt process is terminated. Upon completion of the timer interrupt process, the process returns to the main loop (program address indicated by the stack pointer).

(Evacuation process when power is cut off)
FIG. 13 is a flowchart showing the power-off saving process executed by the main control CPU 73. When the main control CPU 73 receives the power interruption notice signal during interruption of the main routine, the main control CPU 73 interrupts the saving process at the time of power interruption. Further, when the power interruption notice signal is received during execution of the timer interruption process, the interruption process is interrupted after the interruption of the timer interruption process and the return to the main loop.

  As shown in FIG. 13, in the power-off saving process, the value of the AF register is saved in the saving area of the RAM 75 (step S101), and it is determined whether or not a power-off notice signal is received (step S102). Specifically, the input port of the power-off notice signal is bit-checked to determine whether or not the power-off notice signal is input. In this way, by checking again the power-off notice signal immediately after the start of the power-off saving process, it is possible to avoid the execution of the processing after step S106 due to erroneous detection due to noise or the like.

  When the power-off notice signal has not been received (step S103: No), the value of the AF register saved at step S101 is restored (step 104), and the interruption is permitted (step S104), and then the power is cut off. End the save process. Upon completion of the power-off saving process, the main loop (program address indicated by the stack pointer) is restored.

  On the other hand, when the power-off notice signal is received (step S103: Yes), the clear value is output to all the output ports (output port request buffers) (step S106). As a result, all signals stored in the output port request buffer before this processing are deleted and not transmitted.

  Next, among the work areas of the RAM 75 (user work areas including the use prohibition area and the stack area), check sum values are calculated for areas excluding the backup determination storage area and the sum check buffer, and the calculated check sum values are summed. Save in the check buffer (step S108).

  Next, a backup validity judgment value (backup validity judgment flag) is stored in the backup judgment storage area (step S108), access to the work area of the RAM 75 is prohibited (step S109), and a power-off standby process is executed.

  In the power-off standby process, a certain amount of standby time (for example, about several tens of ms) is secured when the power is turned off, and the power-off notice signal of the input port 2 is checked during that time. In this embodiment, a loop counter for 80 ms is set to wait for a reset signal (step S110), and the input port of the power-off notice signal is bit-checked while decrementing the value of the loop counter (step S111). If a power-off notice signal is input before 80 ms elapses (before the loop counter reaches 0) (step S112: Yes), the process returns to the beginning of the power-off standby process (step S110). This process is continued until 80 ms elapses without inputting the power-off notice signal (Step S112: Yes → Step S110, or Step S112: No → Step S113: No → Step S111), and the power-off notice signal is input. If 80 ms elapses (step S112: No → step S113: Yes), the power-off saving process is terminated, and the process proceeds to the CPU initialization process (step S1 in FIG. 7). The power-off standby process makes it possible to shift to the CPU initialization process after a stable state in which the power-off notice signal is not input for a predetermined time (80 ms) or longer, thereby stabilizing the process and protecting the system. .

  As described above, according to the present embodiment, the timer interrupt process interrupts the main loop in preference to the power-off save process, so even if the power interruption occurs during the execution of the timer interrupt process The timer interrupt process is not interrupted by the power-off saving process, and the power-off saving process starts after the timer interrupt process ends. Therefore, it is possible to minimize the amount of data to be saved in the saving process when the power is turned off, and to avoid the complicated return program.

  That is, in this embodiment, in the power-off saving process, the backup information saving process for saving the contents of the work area of the RAM 75 as backup information in the saving area of the RAM 75, or the saved backup information is restored to the work area of the RAM 75. Thus, since the state return process for returning to the gaming state that was being executed at the time of the previous power-off occurrence is not executed, the storage amount of the save area of the RAM 75 can be reduced. In addition, since the backup information saving process and the state return process are not executed, the return program can be simplified.

  Further, since the power-off notice signal is not monitored by polling, the processing load on the main control CPU 73 can be reduced.

  Further, in the main interrupt process, when the power interruption notice signal is received before the winning determination process (step S125, step S128) is executed (step S124: Yes, step S127: Yes), the winning determination process is not executed. Even if the winning ball detection signal is erroneously input to the main control device due to noise caused by power interruption, payout based on the erroneous input (step S73, step S4) and winning / failing lottery (step S69 to step S71) are executed. Never happen. Therefore, for example, due to a player's fraudulent act of deliberately turning off the power, prize balls are not paid out or a jackpot gaming state is not generated, and unauthorized acquisition of prize balls can be prevented. it can.

  In addition, although the example which fluctuates two types of special symbols was demonstrated in the said embodiment, one type may be sufficient as a special symbol and three or more types may be sufficient as it. In addition, the winning / losing lottery with only one of the special symbols or the normal symbols may be executed to generate a jackpot gaming state.

  As mentioned above, although the embodiment to which the invention made by the present inventor is applied has been described, the present invention is not limited by the discussion and the drawings that form part of the disclosure of the present invention according to this embodiment. That is, it should be added that other embodiments, examples, operation techniques, and the like made by those skilled in the art based on this embodiment are all included in the scope of the present invention.
