  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In this embodiment, a pachinko machine that is a kind of a ball game machine, in particular, a first type pachinko game machine will be described as an example of the game machine. Note that it is naturally possible to use the present invention for the third kind pachinko gaming machine and other gaming machines.

  FIG. 1 is a front view of a game board of a pachinko machine P according to the present embodiment. Around the game board 1, there are provided a plurality of winning holes 2 through which five to fifteen balls are paid out when a ball wins. In the center of the game board 1, a liquid crystal display (hereinafter simply referred to as “LCD”) 3 for displaying symbols as a plurality of types of identification information is provided. The display screen of the LCD 3 is divided into three in the horizontal direction. In each of the three divided display areas, the symbols are displayed in a variable manner while scrolling in the vertical direction from top to bottom.

  Below the LCD 3, a symbol operating port (first type starting port) 4 is provided, and when the ball wins the symbol operating port 4, the above-described variation display of the LCD 3 is started. Below the symbol operating port 4, a specific winning port (large winning port) 5 is provided. This specific winning opening 5 is a big hit when the display result after the fluctuation of the LCD 3 coincides with one of the predetermined symbol combinations, and a predetermined time (for example, 30 seconds elapses) so that the ball is easy to win. (Or until 10 balls have been won).

  A V zone 5a is provided in the specific winning opening 5, and when the ball passes through the V zone 5a while the specific winning opening 5 is opened, a continuation right is established and the specific winning opening 5 is closed. Thereafter, the specific winning opening 5 is opened again for a predetermined time (or until a predetermined number of balls win the specific winning opening 5). The opening / closing operation of the specific winning opening 5 can be repeated up to 16 times (16 rounds), and the state where the opening / closing operation can be performed is a state where a predetermined game value is given (special game state). is there.

  Note that a state in which a predetermined game value is given (special game state) in the third type pachinko gaming machine is specified when the display result after the fluctuation of the LCD 3 matches one of predetermined symbol combinations. It means that the winning opening is opened for a predetermined time. When the ball wins into the specific winning opening while the specific winning opening is opened, a large winning opening provided separately from the specific winning opening is opened a predetermined number of times for a predetermined time.

  FIG. 2 is a block diagram showing the electrical configuration of the pachinko machine P, and in particular, a main control board C that controls the game content of the pachinko machine P, and a payout control board that performs payout control of prize balls and balls. It is the block diagram which showed the electric constitution with H.

  On the main control board C of the pachinko machine P, an MPU 11 as a one-chip microcomputer which is an arithmetic unit is mounted. The MPU 11 includes a ROM 12 storing various control programs executed by the MPU 11 and fixed value data, and a memory for temporarily storing various data and the like when executing the control program stored in the ROM 12. A certain RAM 13 and various circuits such as an interrupt circuit, a timer circuit, and a data transmission / reception circuit are incorporated. The programs of the flowcharts shown in FIGS. 3 to 5 are stored in the ROM 12 as a part of the control program.

  The RAM 13 of the main control board C includes a prize ball buffer 13a, a prize ball pointer 13b, and a backup area 13c. Further, the RAM 13 is configured so that the backup voltage is supplied from the power supply board 50 even after the pachinko machine P is turned off, and data can be held (backed up).

  The prize ball buffer 13a is a buffer for storing the number of prize balls to be paid out when a ball driven into the game area of the game board 1 wins the prize opening 2 or the like. Since the number of winning balls to be paid out is stored in the winning ball buffer 13a for each winning ball, the winning ball buffer 13a is composed of a plurality of bytes. When the prize ball data stored in the prize ball buffer 13a is transmitted to the payout control board H as a prize ball command, it is erased from the prize ball buffer 13a. Specifically, after the number of prize balls stored in the 0th prize ball buffer 13a is transmitted to the payout control board H, the values of the 1st and later prize ball buffers 13a are sequentially shifted to the smaller address side by 1 byte. As a result, the value of the 0th prize ball buffer 13a is erased.

  Here, the prize ball command is a command for instructing the payout control board H of the number of prize balls to be paid out, and is composed of 2 bytes. The first byte data of the prize ball command is data (for example, “A0H”) indicating that the command is a prize ball command, and the second byte data indicates the number of prize balls to be paid out. The data is shown. Since the maximum number of winning balls for one winning is 15 balls, 15 types of data “01H” to “0FH” corresponding to the maximum number of winning balls are used as the second byte data of the winning ball command. Yes.

  The prize ball command may be composed of 1 byte. As described above, since the maximum number of winning balls for one winning is 15 balls, when the winning ball command is composed of 1 byte, “01H” to “0FH” corresponding to the maximum winning ball number. Fifteen types of data are used as prize ball commands. In other words, when the upper 4 bits of a command composed of 1 byte are “0”, a winning ball command is set.

  The prize ball pointer 13b is a pointer indicating the position of the prize ball buffer 13a for storing the number of prize balls, and the number of prize balls to be paid out is stored in the value-th prize ball buffer 13a of the prize ball pointer 13b. The value of the prize ball pointer 13b is incremented by "1" by writing the number of prize balls in the prize ball buffer 13a, and conversely, the value of the 0th prize ball buffer 13a is transmitted to the payout control board H. “1” is subtracted.

  In the backup area 13c, when the power is cut off due to the occurrence of a power failure or the like, the power of the pachinko machine P is restored to the state before the power is turned off when the power is turned on again. This is an area for storing stack pointers, values of registers, I / O, and the like. The writing to the backup area 13c is executed when the power is turned off by the backup process executed in the main process. Conversely, the restoration of each value written to the backup area 13c is performed when the power is turned on (the power is turned on by eliminating the power failure). The same applies hereinafter (see FIG. 3).

  The MPU 11 incorporating the ROM 12 and the RAM 13 is connected to an input / output port 15, and the input / output port 15 is connected to a payout control board H that performs payout control of prize balls and balls by a prize ball payout motor 21. In addition, a plurality of normal winning switches 17, a first type start port switch 18, a V count switch 19, a 10 count switch 20, another input / output device 25, and a power failure monitoring circuit 50b provided on the power supply board 50. And the clear switch 50c.

  The normal winning switch 17 is a switch for detecting a ball that has won a plurality of winning holes 2 provided on the game board 1, and is provided near the entrance of each winning hole 2. The first type starting port switch 18 is a switch for detecting a sphere that has passed through the symbol operating port (first type starting port) 4, and is provided in the vicinity of the symbol operating port 4. When a ball is detected by any of the normal winning switches 17 or the first type start port switch 18, five paying balls are paid out by the payout control board H.

  The V count switch 19 is a switch for detecting a ball won in the V zone 5 a in the specific winning opening 5, and the 10 count switch 20 is a ball won in a place other than the V zone 5 a in the specific winning opening 5. It is a switch for detecting. When a ball is detected by the V count switch 19 or the 10 count switch 20, 15 prize balls are paid out by the payout control board H.

  Here, the input / output ports 15 and 35 are connected to the main control board C and the payout control board H via a plurality of data lines. Therefore, transmission / reception of a prize ball command or the like between the main control board C and the payout control board H is not only performed in one direction from the main control board C to the payout control board H, but also from the payout control board H to the main control board H. This is also performed on the control board C.

  The payout control board H performs payout control of prize balls and rental balls, and is equipped with an MPU 31 that is an arithmetic unit. The MPU 31 includes a ROM 32 that stores a control program executed by the MPU 31, fixed value data, and the like, and a RAM 33 that is used as a work memory or the like. The programs of the flowcharts shown in FIGS. 4 and 6 to 8 are stored in the ROM 32 as a part of the control program.

  The RAM 33 of the payout control board H includes a remaining ball number counter 33a, an initialization flag 33b, and a backup area 33c. Further, the RAM 33 is configured so that the backup voltage is supplied from the power supply board 50 even after the power of the pachinko machine P is turned off, and data can be retained (backed up).

  The remaining prize ball counter 33a is a counter for storing the number of unpaid prize balls. The value of the remaining prize ball number counter 33a is incremented every time the prize ball is instructed from the main control board C to the payout control board H by the prize ball command. On the contrary, every time the prize ball count switch 22 detects the paid out prize ball, “1” is subtracted. The payout control board H operates the award ball payout motor 21 to pay out the award balls until the value of the remaining award ball number counter 33a reaches “0”. Since the value of the counter 33a is backed up by the backup voltage supplied from the power supply board 50, even if the power of the pachinko machine P is cut off during the payout of the prize ball, the power of the pachinko machine P must be turned on again. Thus, the payout control board H can accurately pay out the remaining prize balls (unpaid prize balls).

  The initialization flag 33b is a flag that is turned on when the payout control board H receives an initialization command transmitted from the main control board C. The initialization command is a command that is transmitted when the start-up process of the main control board C is completed (see S9 in FIG. 3), and the payout control board H is permitted to start paying out a prize ball and launching a ball. Is a command to give The payout control board H requires less processing than the main control board C at the time of start-up, and the main control board C completes the payout of the winning ball and the preparation for launching the ball before the game control can be started. However, if the payout control board H starts to control the game before the main control board C starts to control the game, problems such as the detection of the payout of the prize ball on the main control board C occur. The payout control board H waits for the start of control until the control board C can start controlling the game. When the payout control board H receives the initialization command and the initialization flag 33b is turned on, the payout control board H recognizes that the main control board C finishes the start-up process and the game control is started, The payout control board H turns off the initialization flag 33b and starts control of the game (see FIG. 7).

  Similarly to the backup area 13c of the main control board C described above, when the power is cut off due to a power failure or the like, the backup area 33c returns the pachinko machine P to the state before the power is turned off when the power is turned on again. This is an area for storing values such as a stack pointer at the time of power-off, each register, and I / O. The writing to the backup area 33c is executed when the power is turned off by the backup process executed in the main process, and the return of each value written to the backup area 33c is executed when the power is turned on (FIG. 7). reference).

  The MPU 31 incorporating these ROM 32 and RAM 33 is connected to an input / output port 35. The input / output port 35 is connected to the main control board C described above, as well as a prize ball payout motor 21 and a prize ball count switch. 22, another input / output device 25, and a power failure monitoring circuit 50 b and a clear switch 50 c provided on the power supply substrate 50, respectively.

  The prize ball count switch 22 is a switch for detecting a prize ball paid out by the prize ball payout motor 21, and is mounted on the prize ball payout unit together with the prize ball payout motor 21. The winning ball payout motor 21 is a motor for paying out a winning ball, and the driving of the winning ball payout motor 21 is controlled by the payout control board H.

  The power supply board 50 includes a power supply unit 50a for supplying power to each unit of the pachinko machine P, a power failure monitoring circuit 50b, and a clear switch 50c. The power failure monitoring circuit 50b is a circuit for outputting a power failure signal 51 to the main control board C and the payout control board H when the power is cut off due to the occurrence of a power failure or the like. This power failure monitoring circuit 50b monitors the DC stable voltage of 24 volts, which is the largest voltage output from the power supply unit 50a. If the voltage is 22 volts or higher, a high signal is sent to the main control board C and the payout control board. Output to H input / output ports 15 and 35.

  The power failure monitoring circuit 50b determines that a power failure has occurred when the voltage output from the power supply unit 50a is less than 22 volts, and switches the output of the power failure signal 51 from high to low. The main control board C and the payout control board H monitor the power failure signal 51 input from the input / output ports 15 and 35 by the main processing, and recognize that a power failure has occurred when the power failure signal 51 goes low, A backup process (see FIG. 4) for writing data based on the state to the backup areas 13c and 33c is executed. Further, when the output of the power failure signal 51 is switched from low to high, the main control board C and the payout control board H recognize that the power failure has been resolved, and perform the process before or after the execution of the backup process. Shift to the pre-power failure process and resume game control. Note that the power supply unit 50a outputs an output of 5 volts, which is the drive voltage of the control system, for a time sufficient to execute the process at the time of the power failure even after the DC stable voltage of 24 volts becomes less than 22 volts. The main control board C and the payout control board H are configured to be maintained at normal values, and can reliably execute the processing at the time of power failure.

  Here, in the pachinko machine P of the present embodiment, the power failure signal 51 output from the power failure monitoring circuit 50b is continuously kept low until the power failure is resolved after the occurrence of the power failure. It is output to the input / output ports 15 and 35 of H. For this reason, the main control board C and the payout control board H can be used as an opportunity to check the state of the power failure signal 51 at a convenient timing in the control and start the power failure processing, and to perform the power failure signal multiple times. The state of 51 can be confirmed. Therefore, in the event of an instantaneous power outage that eliminates the power outage during the backup process (see FIG. 4) or a power outage based on an erroneous signal input due to noise or the like, the power outage signal 51 is set again after performing the backup process. If the power failure signal 51 is confirmed to be high and the power failure has been resolved, normal game control can be resumed.

  The clear switch 50c is a switch for clearing data backed up in the RAM 13 of the main control board C and the RAM 33 of the payout control board H, and is configured as a push button type switch. When the power of the pachinko machine P is turned on while the clear switch 50c is pressed (including power-on due to power failure cancellation), the data in the RAMs 13 and 33 is cleared by the main control board C and the payout control board H. Is done.

  Next, each process performed in the main control board C and the payout control board H will be described with reference to the flowcharts shown in FIGS. FIG. 3 is a flowchart of a main process executed on the main control board C of the pachinko machine P. The main control of the pachinko machine P is executed by this main process.

  In the main process, interrupts are first prohibited (S1). Next, a stack pointer is set (S2), and it is confirmed whether or not the clear switch 50c is turned on (S3). If the clear switch 50c is not turned on (S3: No), it is confirmed whether the backup is valid (S4). This confirmation is determined by whether or not the keyword written in a predetermined area of the RAM 13 is correctly stored. If the keyword is stored correctly, the backup is valid. On the other hand, if the keyword is not correct, the backup data is destroyed, so the backup is not valid. If the backup is valid (S4: Yes), the process proceeds to S6, and each state of the main control board C is returned to the state before the power is turned off. On the other hand, if the backup is not valid (S4: No) or the clear switch 50c is turned on (S3: Yes), RAM clear and initialization processing is executed (S5), and the RAM 13 and I / O, etc. Are initialized, and the process proceeds to S8. In the initialization process of S5, a timer interrupt is also set. Examples of the timer interrupt include a timer interrupt that generates a strobe signal for transmitting a control command such as an initialization command or a prize ball command to the payout control board D.

  In the power recovery process from S6, first, the value of the stack pointer is read from the backup area 13c, and this value is written to the stack pointer to return to the state before the power interruption (before power failure) (S6). Next, the data of each register and I / O saved in the backup area 13c is read from the backup area 13c, the data is written to the original register and I / O (S7), and the process proceeds to S8. To do. By the processes of S6 and S7, the game control on the main control board C is restored to the state before the power is turned off.

  In the process from S8, the interrupt is permitted (S8), and an initialization command is transmitted to the payout control board H using the interrupt (S9), and the initialization process is executed on the main control board C. This can be reported to the payout control board H. Since the payout control board H is lighter in processing than the main control board C, the start-up process ends before the main control board C. Therefore, the payout control board H can reliably receive the initialization command transmitted from the main control board C. After transmission of the initialization command, the process proceeds to S10 and game control is started. If there is a control board that takes longer to start than the main control board, a wait process that waits for a predetermined time may be executed before the process proceeds to S10. It is possible to prevent a command from being transmitted from the main control board C before each control board can receive a command for controlling a game transmitted from the main control board C.

  In the process of S10, it is confirmed whether or not the power failure signal 51 is high (S10). If the power failure signal 51 is high (S10: Yes), since the power failure has not yet occurred, the game of the pachinko machine P is controlled. Each process is executed (S11). Each control of the game of the pachinko machine P including the prize ball process shown in FIG. 5 is executed in each process (S11). After the process of S11, the elapsed time from the previous execution of the process of S10 is confirmed (S12). As a result of the confirmation, if the predetermined time (2 ms in the present embodiment) has not elapsed since the start of the previous processing of S10 (S12: No), the elapsed time is confirmed again after waiting for the transition of the processing. When 2 ms elapses from the start of the previous process of S10 (S12: Yes), the process proceeds to S10.

  On the other hand, if the power failure signal 51 is not high in the process of S10 (S10: No), the power may have been cut off due to the occurrence of a power failure or the like. In this case, wait processing for waiting for a predetermined time is executed (S13), and then the power failure signal 51 is reconfirmed to confirm whether a power failure has occurred or whether the power failure signal 51 is erroneously input due to noise or the like. It is confirmed again whether it is high (S14). Note that the wait process of S13 waits for a predetermined time process so as to remove the influence of noise in consideration of the case where an erroneous power failure signal 51 due to noise is input.

  As a result of the confirmation in S14, if the power failure signal 51 is high (S14: Yes), the power failure has occurred due to an instantaneous power failure or noise, and the power failure has been resolved. The game control is resumed. Thus, after confirming whether or not there is a power outage in the process of S10, it is confirmed again whether or not a power outage is occurring in the process of S14, so that an erroneous power outage signal 51 due to noise or the like is instantly eliminated. In this case, the game control can be resumed promptly. Note that the number of times that the power failure signal 51 is confirmed in the process of S14 is not necessarily limited to one. If there is sufficient time to perform the backup process executed in the process of S16 after the power failure occurs and before the control system drive voltage decreases and becomes uncontrollable, the number of confirmations may be increased. A more accurate determination can be made by determining whether or not there is a power outage based on many confirmations.

  In the process of S14, if the power failure signal 51 is not high (S14: No), the power failure state continues, so interrupts are prohibited (S15) and the recovery process after the power failure is resolved (S6, S7). The backup process (S16) shown in FIG. 4 is executed. Here, the backup process will be described with reference to the flowchart of FIG.

  FIG. 4 is a flowchart of backup processing executed separately on the main control board C and the payout control board H when the power of the pachinko machine P is cut off due to the occurrence of a power failure or the like. By this backup processing, the states of the main control board C and the payout control board H when the power is cut off due to the occurrence of a power failure or the like are stored in the backup areas 13c and 33c. Note that the backup process performed on the payout control board H is not completely the same as the backup process (S16) performed on the main control board C, but is the same as the flowchart and will be described with the same numbers.

  In the backup process (S16), first, the values of each register and I / O are written to the stack area (S51), and then the values of the stack pointer are written to the backup areas 13c and 33c and saved (S52). Further, the power failure occurrence information is written in the backup areas 13c and 33c (S53), and the state at the time of power failure due to the occurrence of the power failure is stored. Thereafter, other power failure processing is executed (S54), and the backup processing is terminated.

  Returning to the flowchart of FIG. In the processing from S17, it is confirmed whether or not the power failure signal 51 is high (S17). If the power failure signal 51 is not high (S17: No), the wait processing is executed (S18), and then the processing is performed in S17. Then, the power failure signal 51 is confirmed again (S17). The processes of S17 and S18 are repeatedly executed until the drive voltage becomes less than 5 volts and control becomes impossible or the power failure is resolved.

  In the process of S17, if the power failure signal 51 is high (S17: Yes), it means that the power failure has been resolved, so the value of the stack pointer is read from the backup area 13c and the state before executing the backup process of S16. Return (S19), the game information regarding the game state before the power failure written in the backup area 13c is cleared (S20). Furthermore, the interruption is permitted (S21), the process proceeds to S11, and the game control is continued from the game state before the power failure.

  Here, the conventional pachinko machine is driven when backup processing is performed when an instantaneous power outage that eliminates the power outage during the power outage processing or a power outage based on erroneous signal input due to noise or the like is detected. Before the voltage went down, the power-off standby state was entered, and it was not possible to restore the gaming state before the power failure unless the power was cut off and the backed up data was restored.

  On the other hand, in the pachinko machine P of this embodiment, in the main process of the main control board C, the power failure is resolved after the power failure signal 51 input to the input / output port 15 is high and the occurrence of the power failure is confirmed. Confirm whether or not. If it is determined that the power failure has been resolved, the process is transferred to each process (S11) in which the game control is performed, and the game control is resumed. Therefore, compared to the case where a power failure occurs based on the input of one power failure signal 51 and backup processing is executed, a power failure due to an erroneous power failure signal 51 input or a short-time power failure that instantly eliminates power failure Therefore, the game control can be resumed quickly, and control resistant to noise can be performed. Further, even after the game information is written in the backup area 13c by the backup process (S16), it is confirmed whether or not the power failure has been resolved, so that the game information can be preferentially saved to the backup area 13c. At the same time, when the power failure is resolved after the retreat, the game control can be reliably resumed.

  Further, the power failure signal 51 input to the input / output port 15 is confirmed in the process of S10, and the process proceeds to the backup process (S16) based on the confirmation result. Therefore, the backup is performed during the execution of each process (S11). The process (S16) is not interrupted. In the conventional pachinko machine, the backup process is executed by an interrupt process in which the prohibition setting of the interrupt is impossible. However, the backup process is interrupted and executed because the timing of the occurrence of the power failure cannot be specified. Therefore, it is necessary to program each process for controlling the game and the backup process so that there is no problem when the backup process is executed, and the program becomes complicated and the capacity is increased. However, according to the pachinko machine P, since the power failure signal 51 is continuously input to the input / output port 15 during a power failure, whether or not a power failure has occurred in a predetermined process (S10) as part of the main process. If a power failure occurs, the process can be shifted to the backup process (S16). Therefore, it is possible to simplify the program by specifying the execution time of the backup process (S16) and to reduce the capacity of the program.

  FIG. 5 is a flowchart of the prize ball process executed in each process of the main control board C (see S11 in FIG. 3). The winning ball process includes a winning detection process (S30) for detecting a winning ball in the winning slot 2, the first type starting port 4 or the specific winning slot 5, and a winning ball command transmission for transmitting a winning ball command to the payout control board H. The process is composed of two processes (S40).

  In the winning detection process (S30), first, it is confirmed whether or not a ball is detected by any of the normal winning switch 17 or the first type start port switch 18 (S31). When a ball is detected by any of the switches 17 and 18 (S31: Yes), in order to pay out five prize balls, “5” is given to the value-th prize ball buffer 13a of the prize ball pointer 13b. Write (S32) and add "1" to the value of the prize ball pointer 13b (S33). On the other hand, when a sphere is not detected by any of the switches 17 and 18 (S31: No), the process of S32 and S33 is skipped, and the process proceeds to S34.

  In the process of S34, it is confirmed whether or not a sphere is detected by the V count switch 19 or the 10 count switch 20 (S34). When a ball is detected by any of the switches 19 and 20 (S34: Yes), “15” is set to the value-th prize ball buffer 13a of the prize ball pointer 13b in order to pay out 15 prize balls. Write (S35), and add "1" to the value of the prize ball pointer 13b (S36). On the other hand, if no ball is detected by any of the switches 19 and 20 (S34: No), the process of S35 and S36 is skipped, the winning detection process (S30) is terminated, and the process is awarded in S40. The process proceeds to the sphere command transmission process.

  In the prize ball command transmission process (S40), it is first checked whether or not the value of the prize ball pointer 13b is "0" (S41). If the value of the prize ball pointer 13b is not “0” (S41: No), it means that the prize ball data to be paid out is stored in the prize ball buffer 13a, and therefore the value of the 0th prize ball buffer 13a. Is set as the second byte data of the prize ball command, and the prize ball command is transmitted to the payout control board H (S42). After the prize ball command is transmitted, the value of the first and subsequent prize ball buffers 13a is shifted one byte at a time to the smaller address side (S43), the value of the prize ball buffer 13a is updated, and the transmitted zeroth The value of the prize ball buffer 13a is erased, and the value of the prize ball pointer 13b is subtracted by “1” (S44). On the other hand, if the value of the prize ball pointer 13b is “0” in the process of S41 (S41: Yes), the data of the number of prize balls to be paid out is not stored in the prize ball buffer 13a. Each process is skipped, and the prize ball command transmission process (S40) is terminated. Thereby, the prize ball processing of FIG. 5 ends.

  Next, each process performed on the payout control board H will be described with reference to FIGS. FIG. 6 is a flowchart of command reception processing executed in the interruption processing of the payout control board H. When the payout control board H receives a command transmitted from the main control board C, an interrupt is generated each time, and this command reception process is executed. Note that the interrupt for executing this command reception processing is not a non-maskable interrupt that cannot be set for interrupt prohibition, but an interrupt that can be set for interrupt prohibition.

  In the command reception process, first, it is determined whether or not the received command is an initialization command (S61). If the command is an initialization command (S61: Yes), the initialization flag 33b is turned on to store the reception of the initialization command (S62), and the command reception process is terminated. On the other hand, if the received command is not an initialization command (S61: No), it is determined whether or not the command is a prize ball command (S63). If the received command is a prize ball command (S63: Yes), the number of prize balls designated as the second byte data of the prize ball command is added to the remaining prize ball number counter 33a (S64). The process ends. On the other hand, if the received command is not a prize ball command (S63: No), a process corresponding to the received command is executed (S65), and the command receiving process is terminated.

  FIG. 7 is a flowchart of a main process executed on the payout control board H of the pachinko machine P. In the main process of the payout control board H, interrupts are first prohibited (S71). Next, a stack pointer is set (S72), and it is confirmed whether or not the clear switch 50c is turned on (S73). If the clear switch 50c is not turned on (S73: No), it is confirmed whether the backup is valid (S74). This confirmation is determined by whether or not the keyword written in the predetermined area of the RAM 33 is correctly stored. If the keyword is stored correctly, the backup is valid. On the other hand, if the keyword is not correct, the backup data is destroyed, so the backup is not valid. If the backup is valid (S74: Yes), the process proceeds to S76, and each state of the payout control board H is returned to the state before the power-off. On the other hand, if the backup is not valid (S74: No) or the clear switch 50c is turned on (S73: Yes), RAM clear and initialization processing is executed (S75), and the RAM 33, I / O, etc. Each value is initialized, and the process proceeds to S78. In the initialization process of S75, a timer interrupt is also set.

  In the power recovery process from S76, first, the value of the stack pointer is read from the backup area 33c, and this value is written to the stack pointer to return to the state before the power interruption (before power failure) (S76). Next, each register and I / O data saved in the backup area 33c is read from the backup area 33c, and each data is written to the original register and I / O (S77), and the process proceeds to S78. To do. As a result, the game control on the payout control board H is restored to the state before the power is turned off.

  In the process from S78, the interrupt is permitted (S78), the above-described command reception process of FIG. 6 is made executable, and it is confirmed whether or not the initialization flag 33b is turned on (S79). If the initialization flag 33b is not turned on (S79: No), it means that the initialization command transmitted when the startup process of the main control board C is completed is not received, so the process of S79 is repeatedly executed. And wait. When the initialization flag 33b is turned on in the process of S79 (S79: Yes), the startup process of the main control board C is completed, so the initialization flag 33b is turned off (S80), and the process proceeds to S81. .

  In the process of S81, it is confirmed whether or not the power failure signal 51 is high (S81). If the power failure signal 51 is high (S81: Yes), since the power failure has not yet occurred, the game of the pachinko machine P is controlled. Each process is executed (S82). Control of the payout control board H including a prize ball payout process of FIG. 8 to be described later is executed in each process (S82) except for the interrupt process. After the process of S82, the elapsed time from the previous execution of the process of S81 is confirmed (S83). As a result of the confirmation, if the predetermined time (2 ms in the present embodiment) has not elapsed since the start of the previous processing of S81 (S83: No), the elapsed time is confirmed again after waiting for the transition of the processing. When 2 ms elapses from the start of the previous process of S81 (S83: Yes), the process proceeds to S81.

  On the other hand, if the power failure signal 51 is not high in the process of S81 (S81: No), the power may have been cut off due to the occurrence of a power failure or the like. In this case, a wait process for waiting for a predetermined time is executed (S84), and then a power failure signal 51 is generated in order to reconfirm whether a power failure has occurred or whether an erroneous power failure signal 51 is input due to noise or the like. It is confirmed again whether it is high (S85). Note that the wait process in S84 waits for a predetermined time process so as to remove the influence of noise in consideration of the case where an erroneous power failure signal 51 due to noise is input.

  If the power failure signal 51 is high as a result of the confirmation in S85 (S85: Yes), the power failure has occurred due to an instantaneous power failure or noise, and the power failure has been resolved. Therefore, the processing is shifted to each processing in S82. The game control by the payout control board H is resumed. Similar to the control of the main control board C, after confirming whether or not there is a power outage in the process of S81, it is confirmed again whether or not a power outage is occurring in the process of S85. In the event that a power outage is eliminated or instantaneously, the game control can be resumed promptly. Note that the number of times that the power failure signal 51 is confirmed in the processing of S85 is not necessarily limited to one. If there is sufficient time to perform the backup process of S16 after the power failure occurs and before the control system drive voltage drops and becomes uncontrollable, the number of confirmations may be increased. A more accurate determination can be made by determining whether or not there is a power outage based on many confirmations.

  If the power failure signal 51 is not high in the processing of S85 (S85: No), the power failure state continues, so interrupts are prohibited (S86), and the recovery processing after the power failure is resolved (S76, S77). Then, the backup process (S16) shown in FIG. 4 is executed.

  In the processing from S87, it is confirmed whether or not the power failure signal 51 is high (S87). If the power failure signal 51 is not high (S87: No), the wait processing is executed (S88), and then the processing is performed in S87. Then, the power failure signal 51 is confirmed again (S87). The processes of S87 and S88 are repeatedly executed until the drive voltage becomes less than 5 volts and control becomes impossible or the power failure is eliminated.

  In the process of S87, if the power failure signal 51 is high (S87: Yes), it means that the power failure has been resolved, so the value of the stack pointer is read from the backup area 33c and the state before executing the backup process of S16. Return (S89), the game information regarding the game state before the power failure written in the backup area 33c is cleared (S90). Furthermore, the interruption is permitted (S91), the process proceeds to S82, and the game control is continued from the game state before the power failure.

  Thus, in the main process of the payout control board H, after confirming that the power failure signal 51 is high, it is confirmed again whether or not the power failure has been resolved. Therefore, based on a single power failure signal 51 input. Compared to the case where a power failure occurs and backup processing is executed, the game control is promptly resumed for a power failure caused by an incorrect power failure signal 51 input or a short-term power failure that instantly eliminates power failure. Can do. Further, even after the game information is written in the backup area 33c by the backup process (S16), it is confirmed whether or not the power failure has been resolved, so that the game information can be preferentially saved to the backup area 33c. At the same time, when the power failure is resolved after the retreat, the game control can be reliably resumed.

  FIG. 8 is a flowchart of the winning ball payout process executed in each process (S82) of the payout control board H. With the prize ball payout process, the prize balls are paid out and the prize balls that have been paid out are detected. In the prize ball payout process, first, the value of the remaining prize ball number counter 33a is checked (S101). If the value is not "0" (S101: No), an unpaid prize ball remains, so a prize ball is paid out. The motor 21 is driven to pay out one prize ball (S102). On the other hand, if the value of the remaining prize ball counter 33a is “0” (S101: Yes), there is no unpaid prize ball remaining, so the prize ball payout process in S102 is skipped.

  In the process of S103, it is confirmed whether or not the prize ball count switch 22 is turned on (S103). As a result of the confirmation, if it is detected that the prize ball count switch 22 is turned on (S103: Yes), it means that the prize ball has been paid out. Therefore, in such a case, the value of the remaining prize ball counter 33a is confirmed (S104), and if the value is not “0” (S104: No), the remaining prize ball corresponding to the paid-out prize ball. The value of the number counter 33a is decremented by “1” (S105), and this prize ball payout process is terminated. On the other hand, if the prize ball count switch 22 is not turned on (S103: No) or the prize ball count switch 22 is turned on (S103: Yes), the value of the remaining prize ball counter 33a is “0”. If so (S104: Yes), the process of S105 is skipped and this prize ball payout process is terminated.

  Here, conventionally, there is a pachinko machine that executes a backup process by using an interrupt process when a power failure occurs. In this type of pachinko machine, the backup process may be executed while the counter value is being updated. . For this reason, it is necessary to create a backup processing program that assumes that data being updated is saved, and the progress of the processing must be backed up. Was the cause of the increase in size. However, according to the pachinko machine P of the present embodiment, when a power failure occurs, data is backed up by the backup process (S16) executed in the main process shown in FIG. For this reason, backup processing is not performed during the update of the remaining prize ball number counter 33a and the like, and the value of the remaining ball number counter 33a that has been updated may be saved in the backup area 33c. Therefore, programs such as the backup process (S16) and the return process (S76, S77) can be simplified and the storage capacity required for backup can be reduced.

  Next, a second embodiment will be described with reference to FIGS. In the first embodiment described above, the power failure signal 51 output from the power failure monitoring circuit 50b of the power supply board 50 is input to the input / output ports 15 and 35 of the main control board C and the payout control board H, respectively. The occurrence of a power failure was detected in the main processing performed at H.

In contrast, in the second embodiment, power failure flags 63d and 73d are provided in the MPUs 61 and 71 of the main control board C and the payout control board H, respectively, and a power failure occurs from the power failure monitoring circuit 80b of the power supply board 80 when a power failure occurs. The signal 81 is sent to the NMI (Non Maskable) of each MPU 61, 71.
Interrupt) terminal (non-maskable interrupt terminal), and the power failure flags 63d and 73d are turned on by NMI interrupt processing (see FIG. 10). The states of the power failure flags 63d and 73d are periodically checked in the main processing (see FIGS. 11 and 12) performed on the control boards C and H, and the power failure flags 63d and 73d are turned on to detect the occurrence of a power failure. If a power failure occurs, the power failure signal 51 input to the input / output ports 15 and 35 is confirmed to determine whether or not a power failure has occurred. Hereinafter, in the description of the second embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  FIG. 9 is a block diagram showing an electrical configuration of the pachinko machine P in the second embodiment. The MPU 61 of the main control board C is provided with a power failure flag 63 d in its RAM 63. The power failure flag 63d is a flag for reporting a power failure due to the occurrence of a power failure or the like. When a power failure occurs, the power is cut off, and a power failure occurrence signal 81 output from the power failure monitoring circuit 80b of the power supply board 80 is input to the NMI terminal of the MPU 61, the MPI 61 causes the NMI interrupt shown in FIG. The process is executed and the power failure flag 63d is turned on. When the power failure flag 63d is turned on, the occurrence of a power failure is confirmed in the main processing of the main control board C (see FIG. 11), and backup processing for saving each data indicating the game state (see FIG. 11, S16). The processing shifts to etc.

  Similarly to the MPU 61 of the main control board C described above, the MPU 71 of the payout control board H is provided with a power failure flag 73d in its RAM 73. The power failure flag 73d is also a flag for reporting a power failure due to the occurrence of a power failure or the like. When the power failure occurrence signal 81 output from the power failure monitoring circuit 80b of the power supply board 80 is input to the NMI terminal of the MPU 71, the MPU 71 The NMI interruption process shown in FIG. 10B is executed, and the power failure flag 73d is turned on. When the power failure flag 73d is turned on, the occurrence of a power failure is confirmed in the main processing of the payout control board H (see FIG. 12), and backup processing for saving each data indicating the game state (see FIG. 12, S16). The processing shifts to etc.

  Similar to the power supply board 50 of the first embodiment, the power supply board 80 includes a power supply unit 50a, a power failure monitoring circuit 80b, and a clear switch 50c. The configuration of the power supply unit 50a and the clear switch 50c is the same as that of the power supply board 50 of the first embodiment, and the configuration of the power failure monitoring circuit 80b is different from that of the power failure monitoring circuit 50b of the first embodiment. The power failure monitoring circuit 80b outputs a power failure signal 51 to the main control board C and the payout control board H, and outputs a power failure occurrence signal 81 to the NMI terminals of the MPUs 61 and 71 of the control boards C and H. When the power failure occurrence signal 81 output from the power failure monitoring circuit 80b is input to each of the MPUs 61 and 71, the NMI interrupt processing shown in FIGS. 10A and 10B is executed, and the RAM 63 of each MPU 61 and 71 is executed. , 73 are turned on.

  10A is executed by the main control board C when a power failure occurrence signal 81 is output from the power failure monitoring circuit 80b due to the occurrence of a power failure, and FIG. 10B is executed separately by the payout control board H. It is a flowchart of a NMI interruption process.

  First, in the NMI interrupt process of FIG. 10A executed by the main control board C, when an NMI interrupt occurs, the main control board C process shown in S122 or S14 to S21 of FIG. It is confirmed whether it is in the middle (S111). If the power failure process is not being executed (S111: No), the power failure flag 63d is turned on (S112). Conversely, if the power failure process is being executed (S111: Yes), the process of S112 is skipped and the NMI interrupt process is terminated. Note that the processing being executed when an NMI interrupt occurs is checked by checking the address saved in the stack when the NMI interrupt occurs.

  Similarly, in the NMI interrupt process of FIG. 10B executed by the payout control board H, is a power failure process shown in S132 or S85 to S91 of FIG. 12 described later executed when an NMI interrupt occurs? It is confirmed whether or not (S113). If the power failure process is not being executed (S113: No), the power failure flag 33d is turned on (S114). Conversely, if it is being executed (S113: Yes), the process of S114 is skipped and this NMI allocation is performed. Finish the process.

  FIG. 11 is a flowchart of a main process executed on the main control board C of the pachinko machine P in the second embodiment. In this process, the processes of S121 and S122 are changed with respect to the main process of the first embodiment shown in FIG.

  In this main process, after the initialization command is transmitted to the payout control board H in the process of S9, it is confirmed whether or not the power failure flag 63d is turned on (S121). If the power failure flag 63d is not turned on (S121: No), each process for controlling the game is executed (S11). After the processing of S11, the elapsed time from the start of the previous processing of S121 is confirmed (S12). If 2 ms has not elapsed (S12: No), the elapsed time is confirmed. When 2 ms has elapsed from the start of the previous processing of S121 (S12: Yes), the processing from S121 is resumed.

  If the power failure flag 63d is turned on in the processing of S121 (S121: Yes), since the power failure occurrence signal 81 is input to the NMI terminal of the MPU 61 of the main control board C, the power failure flag 63d is turned off (S122). The process proceeds to S14. Here, in the main process of the first embodiment shown in FIG. 3, the weight process (S13) for removing the influence of noise is performed before the process of S14 is performed. However, in the main process of the second embodiment, The power failure occurrence signal 81 is input to the MPU 61 of the main control board C during the execution of the process of S11 or S12, and since time has elapsed from the input to the process of S14, the process of S121 is performed. It is possible to eliminate the influence of noise without providing a wait process after the operation. Therefore, the process of S14 for confirming the cancellation of the power failure can be immediately executed, and the confirmation of the power failure cancellation and the backup process (S16) can be performed earlier.

  In the processing from S14, it is confirmed whether or not the power failure signal 51 is high (S14), and if the power failure signal 51 is high and the cancellation of the power failure is confirmed (S14: Yes), the game is controlled. The process proceeds to each process (S11). On the other hand, if the continuation of the power failure is confirmed (S14: No), the backup process (S16) is executed to wait for the power-off. Note that the power failure flag 63d is not turned on by the NMI interrupt processing during the processing of S122 and S14 to S21 (processing at power failure) (see FIG. 10A).

  FIG. 12 is a flowchart of the main process executed on the payout control board H of the pachinko machine P in the second embodiment. In this process, the processing part of S131 and S132 is changed with respect to the main process of the first embodiment shown in FIG.

  After the initialization flag 33b is turned off in the process of S80, it is confirmed whether or not the power failure flag 73d is turned on (S131). If the power failure flag 73d is not turned on (S131: No), each process for controlling the game on the payout control board H is executed (S82). After the process of S82, the elapsed time from the start of the previous process of S131 is confirmed (S83). If 2 ms has not elapsed (S83: No), the elapsed time is confirmed. When 2 ms has elapsed from the start of the previous processing of S131 (S83: Yes), the processing from S131 is resumed.

  If the power failure flag 73d is turned on in the process of S131 (S131: Yes), the power failure occurrence signal 81 is input to the NMI terminal of the MPU 71 of the payout control board H, so the power failure flag 73d is turned off (S132). The process proceeds to S85. Here, as in the main process of the main control board C, in the main process of the first embodiment, the weight process (S84) for removing the influence of noise is performed before the process of S85 is performed. In the main process of the example, since time has elapsed from when the power failure occurrence signal 81 is input to the MPU 71 of the payout control board H to the process of S85, the wait process is not provided after the process of S131. Even noise effects can be removed. Therefore, the process of S85 for confirming the cancellation of the power failure can be immediately executed, and the confirmation of the power failure cancellation and the backup process (S16) can be performed earlier.

  In the processing from S85, it is confirmed whether or not the power failure signal 51 is high (S85), and if the power failure signal 51 is high and the cancellation of the power failure is confirmed (S85: Yes), the game is controlled. The process proceeds to each process (S82). On the other hand, if the continuation of the power failure is confirmed (S85: No), the backup process (S16) is executed to wait for the power-off. Note that during the execution of the processing from S132 and S85 to S91 (processing at power failure), the power failure flag 73d is not turned on by the NMI interrupt processing (see FIG. 10B).

  As described above, the power failure flags 63d and 73d are turned on only when the NMI interrupt processing is executed in addition to the processing during power failure of the control boards C and H. That is, even if the power failure occurrence signal 81 is input to the MPUs 61 and 71 of the control boards C and H during the power failure processing, the power failure flags 63d and 73d are not turned on. Even if the output is disturbed and multiple NMI interrupt processes occur, the power failure flags 63d and 73d are not turned on during the power failure process. Therefore, when it is determined that the power failure has been resolved in the middle of the power failure process, and when returning to each process (S11, S82) in which the game is controlled, the power failure flags 63d and 73d must be surely turned off. It is possible to prevent returning to the power failure process by mistake after it is determined that the power failure has been resolved.

  When the power failure flags 63d and 73d are off, it is not necessary to check the state of the power failure signal 51 of the input / output ports 15 and 35 in the main processing of the control boards C and H, and the power failure flags 63d and 73d. It is only necessary to confirm the state of. Only when the occurrence of a power failure is detected, the power failure signal 51 input to the input / output ports 15 and 35 may be confirmed, and normal processing can be performed with simple control.

In the above embodiment, the game control processing means executed by the main control means according to claim 1 corresponds to the processing of S121, S11, S12 of FIG. 11, and the power failure signal interrupt processing executed by the main control means. The means corresponds to the NMI process shown in FIG. 10A, and the power failure information determination processing means executed by the main control means corresponds to the process of S121 in FIG. 11, and the power failure process executed by the main control means. The means corresponds to the processing of S16 in FIG. 11 (backup processing shown in FIG. 4). Further, the game control processing means executed by the sub-control means according to claim 1 corresponds to the processes of S131, S82, and S83 in FIG. 12, and the power failure signal interrupt processing means executed by the sub-control means is illustrated in FIG. The power failure information determination processing means executed by the sub-control means corresponds to the NMI processing shown in FIG. 10B, and the processing of S131 of FIG. 12 corresponds to the power failure information processing means executed by the sub-control means. 12 corresponds to the process of S16 (the backup process shown in FIG. 4).

  The present invention has been described based on the embodiments. However, the present invention is not limited to the above embodiments, and various modifications can be easily made without departing from the spirit of the present invention. It can be guessed.

  For example, in each of the above embodiments, when a power failure occurs when the drive voltage is less than 22 volts and the power failure occurs before the drive voltage of the control system becomes less than 5 volts and the power is cut off, the main control board C and the payout control board H resumed the control of the game from the same state as before the occurrence of the power failure. However, it is not always necessary to restart the game control in the same state as before the occurrence of the power outage.For example, only the number of unpaid award balls or the state of the big win is backed up. Only the state of the game unit may be restored to resume the game control. By limiting the data that needs to be backed up, it is possible to simplify a program such as a backup process, and it is possible to more quickly save the data to be backed up and restore the backed up data.

  In each of the above embodiments, when the power failure is resolved before the power is turned off after the backup process (S16) is executed in the main process of the control boards C and H, the value of the stack pointer is obtained from the backup areas 13c and 33c. The game state was read out to restore the game state, and the game information written in the backup areas 13c and 33c was cleared to resume the game control. However, it is not always necessary to resume the control of the game by providing these processes, and the game state may be restored by using the same restoration process as the backup data restoration process executed when the power is turned on. That is, when the power failure is resolved after the occurrence of the power failure and before the power supply is cut off, the main process of each control board C, H shown in FIGS. 3, 7, 11, and 12 is executed from the top, and the gaming state May be restored. The game state can be restored using the same restoration process without providing a restoration process for each of the case where the power failure is resolved before the power is turned off and the case where the power failure is resolved after the power is turned off. Therefore, it is possible to resume the control of the game from the game state before the occurrence of the power failure while suppressing the change to the program for performing the conventional backup process.

  Also, in each of the above embodiments, when it is confirmed that a power failure has occurred in the main processing of each control board C, H, the game control on each control board C, H is completely stopped, Although only the processing is executed, it is not always necessary to completely stop the control of the game, and the control of the game may be advanced little by little during the processing at the time of power failure.

  Further, in each of the above embodiments, after the occurrence of a power failure is confirmed in the main processing of each control board C, H, the processing is performed once it is confirmed that the power failure signal 51 becomes high and the power failure has been resolved. Transition to each process (S11, S82) and the game control was resumed. However, it is not always necessary to restart the game control based on one confirmation of the power failure signal 51. The power failure signal 51 is continuously confirmed a predetermined number of times (for example, five times), and all confirmation results indicate that the power failure has been resolved. If it is, it may be determined that the power failure has been resolved. When the power failure is resolved, a high signal is continuously input from the power failure monitoring circuit 50b to the input / output ports 15 and 35 of the control boards C and H. It is possible to make a determination based on the determination, and it is possible to prevent erroneous determination of power failure cancellation.

  Further, in the second embodiment, even if the power failure occurrence signal 81 is input to the control boards C and H, the power failure flags 63d and 73d are confirmed to be turned on in the processing of S121 of FIG. 11 and S131 of FIG. The same processing is performed in the main processing of the control boards C and H. However, when the power failure flags 63d and 73d are turned on, it may be controlled to shorten other processes so that the backup process (S16) can be performed earlier. For example, when the power failure flags 63d and 73d are on, processing for skipping the processing of S12 of FIG. 11 and S83 of FIG. After the occurrence of a power failure, the time until the drive voltage of the control system becomes less than 5 volts at which control cannot be performed is limited. However, the backup process (S16) can be executed earlier to ensure data backup. It can be performed.

  You may implement this invention in the pachinko machine etc. of a different type from the said Example. For example, once a big hit, a pachinko machine (commonly known as a two-time right, a three-time right, etc.) that increases the expected value of the big hit until a big hit state occurs (for example, twice or three times). May also be implemented. Moreover, after the jackpot symbol is displayed, it may be implemented as a pachinko machine that enters a special game state under the condition that a ball is awarded in a predetermined area. Further, in addition to the pachinko machine, various game machines such as an alepacchi, a sparrow ball, a game machine in which a so-called pachinko machine and a slot machine are fused may be used.

  In the slot machine, for example, a symbol is changed by operating a control lever in a state where a symbol effective line is determined by inserting coins, and a symbol is stopped and confirmed by operating a stop button. Is. Therefore, the basic concept of the slot machine is that “a variable display means for confirming and displaying a symbol after a symbol string composed of a plurality of symbols is displayed in a variable manner, and the symbol resulting from the operation of the starting operation means (for example, an operating lever). The change of the symbol is stopped due to the operation of the operation means for stopping (for example, the stop button) or after a predetermined time has elapsed, and the fixed symbol at the time of the stop is a specific symbol Is a slot machine provided with a special game state generating means for generating a special game state advantageous to the player. In this case, the game medium is typically a coin, a medal or the like.

  In addition, as a specific example of a gaming machine in which a pachinko machine and a slot machine are fused, a variable display means for displaying a fixed symbol after a variable symbol row consisting of a plurality of symbols is provided, and a handle for launching a ball is provided. What is not provided. In this case, after throwing a predetermined amount of spheres based on a predetermined operation (button operation), for example, the change of the symbol is started due to the operation of the operation lever, for example, due to the operation of the stop button, or With the passage of time, the fluctuation of the symbol is stopped, and a jackpot state advantageous to the player is generated on the condition that the confirmed symbol at the time of stoppage is a so-called jackpot symbol. A lot of balls are paid out.
