  In a state where the gaming machine 1 is connected to an external power source and the power switch 8a is turned on, power is supplied from the main power supply device 8 through the power supply control units 48 and 58 as shown in FIG. 4 and the sub-board 5 are supplied. On the other hand, when the gaming machine 1 is not connected to an external power source or power is not supplied from the main power supply device 8 because the power switch 8a is off, it is connected to the power supply control units 48 and 58. Electric power is supplied from the backup power supplies 45 and 55. That is, power is supplied from the backup power supplies 45 and 55 instead of the main power supply device 8 during the period when the gaming machine 1 is transported from the manufacturing factory to the amusement shop or outside the business hours of the amusement shop. Storage batteries such as lithium ion secondary batteries and nickel metal hydride storage batteries are used for the backup power supplies 45 and 55. The power supply control units 48 and 58 for switching between the main power supply device 8 and the backup power supplies 45 and 55 may apply a known technique related to power supply switching. For example, a known power supply switching IC can be applied.

  As shown in FIG. 6, when the gaming machine 1 is connected to an external power source and the power switch 8a is turned on, the main power signal from the main power supply device 8 is transmitted to the main board 4 and the sub board. Output to the substrate 5. A door signal from the door opening / closing sensor 60 is output to the main board 4 and the sub board 5. Then, game information and an open / close notification signal are output from the main board 4 to the hall computer 70 via the external connection terminal board 44. In addition, game information, effect information, and opening / closing date / time information are output from the sub-board 5 to the image display unit 9, and game information and the like are output to the hall computer 70 via the external connection terminal board 54.

  Next, the configuration of the main substrate 4 will be described. The main board 4 includes a central processing unit (CPU) (hereinafter also referred to as “main CPU”) 42, a read only memory (ROM) 41, a static random access memory (SRAM) 43, a switching circuit 46, a power supply control unit 48, a clock. A generator 49 and a backup power supply 45 are provided.

  The switching circuit 46 includes a multivibrator element 46a and a CR circuit 46b, and receives a door signal output from the door opening / closing sensor 60. When the switching circuit 46 receives an open signal or a close signal from the door opening / closing sensor 60, the CR circuit 46b is discharged, and the multivibrator element 46a thereby outputs a start signal (output pulse) for a predetermined time (for example, several μsec). Output to.

  The clock generator 49 includes two oscillation circuits (OSC: oscillator) of a high-speed oscillation circuit and a low-speed oscillation circuit, and a switching control unit that controls the operation of the two oscillation circuits. The high-speed oscillation circuit outputs a clock frequency of about 33 MHz, for example. The low-speed oscillation circuit outputs a clock frequency of about 33 kHz, for example.

  The clock generator 49 outputs a high-speed or low-speed clock frequency to the CPU 42 depending on whether the current mode is the active mode (normal power mode) or the sleep mode (power saving mode). That is, when the CPU 42 is in the active mode, the clock generator 49 outputs the clock frequency oscillated from the high-speed oscillation circuit to the CPU 42. On the other hand, when the CPU 42 is in the sleep mode, the operation of the high-speed oscillation circuit stops, and the clock generator 49 outputs the clock frequency oscillated from the low-speed oscillation circuit to the CPU 42. As a result, when in the sleep mode, the CPU 42 monitors the opening and closing of the door 3 and operates with the clock frequency lowered to such an extent that the necessary power consumption can be obtained because the information in the SRAM 43 is retained. . For this reason, power consumption can be saved when in the sleep mode. On the other hand, when in the active mode, the CPU 42 operates at a clock frequency that is high enough to execute games, output data, and store data, and consumes high power.

  The clock generator 49 is not limited to the above configuration, and may have any configuration as long as it can selectively output two high and low frequencies.

  The ROM 41 is a read-only memory. The ROM 41 stores various programs and data for performing game execution control, door opening / closing monitoring processing, and the like since the game machine 1 is manufactured. The SRAM 43 is a readable / writable memory. The SRAM 43 stores various data generated in the process of execution by the CPU 42.

  The CPU 42 (corresponding to the “main control unit”) controls the execution of the game according to the program and data stored in the ROM 41, determines whether to open / close the door based on signals output from the door opening / closing sensor 60 and the switching circuit 46, 3 outputs an opening / closing notification signal for notifying that the opening / closing of 3 has been detected to the hall computer 70, and controls switching between the active mode and the sleep mode.

  Regarding the determination of door opening / closing, the CPU 42 refers to the door signal after receiving the activation signal, and in this embodiment, the CPU 42 determines that the door 3 is opened because the door signal is Low, and the door signal is High. It is determined that the door 3 is closed.

  For switching control between the active mode and the sleep mode, the CPU 42 shifts to the sleep mode when the door 3 is closed and no power is supplied from the main power supply device 8 or when the door 3 is opened. When the door 3 is closed and power is supplied from the main power supply device 8, the mode is shifted to the active mode.

  Next, the configuration of the sub-board 5 will be described. The sub-board 5 includes a CPU (Central Processing Unit) 52 (hereinafter also referred to as “sub CPU”), a ROM (Read Only Memory) 51, an SRAM (Static Random Access Memory) 53, a switching circuit 56, a clock module 57, and power supply control. Unit 58, a clock generator 59, and a backup power supply 55.

  The configuration of the switching circuit 56, the power supply control unit 58, the clock generator 59 and the backup power supply 55 has the same configuration as the switching circuit 46, the power supply control unit 48, the clock generator 49 and the backup power supply 45 provided in the main board 4. .

  The clock module 57 is configured to include, for example, a crystal oscillator and measures the date and time.

Are stored in the SRAM 53 (corresponding to the “storage unit”), switching control between the active mode and the sleep mode is performed. Regarding the storage of the opening / closing date / time information, the CPU 52 acquires the current date / time from the clock module 57 when receiving the activation signal, and stores the information indicating the date / time in the SRAM 53 as the opening / closing date / time information. The door opening / closing determination and the switching control between the active mode and the sleep mode performed by the CPU 52 are the same as the control performed by the CPU 42 of the main control unit 4 described above. Detailed control performed by the CPUs 42 and 52 will be described later with reference to flowcharts shown in FIGS.

  The image display unit 9 includes a liquid crystal display 91, a CPU, a ROM, and a VDP (Video Display Processor), and performs display control of characters, images, and the like based on a control signal from the sub board 5. For example, the image display unit 9 receives the opening / closing date / time information stored in the SRAM 53 from the sub-board 5 when the fraud confirmation operation switch 14 is operated, and the CPU of the image display unit 9 is based on the opening / closing date / time information. For example, the door opening / closing history screen shown in FIG. 7 is displayed on the liquid crystal display 91.

Further, when the hall computer 70 receives the opening / closing notification signal from the main board 4, the hall computer 70 acquires the current date / time from the clock module, and stores information indicating the date / time in the storage device as the opening / closing date / time information. When the hall computer 70 receives an opening / closing history display instruction by operating a keyboard or the like from an amusement store employee or the like, the hall computer 70 opens, for example, a door opening / closing history screen shown in FIG. 7 based on the opening / closing date / time information stored in the storage device. Is displayed on the display device.

(Unauthorized monitoring process)
Next, various processing examples of fraud monitoring processing performed by the main board 4 and the sub board 5 will be described with reference to flowcharts shown in FIGS. As an initial state of each fraud monitoring process shown in FIGS. 8 to 11, a case where there is no power supply from the main power supply device 8 (during sleep mode operation by the backup power supply 55) will be described as an example.

(First fraud monitoring process performed by the main board)
First, the first fraud monitoring process performed by the main board 4 will be described with reference to the flowchart shown in FIG.

  The CPU 42 of the main board 4 monitors a signal transmitted as an interrupt signal from the door opening / closing sensor 60 via the switching circuit 46 (step S101).

  As a result of monitoring, an activation signal is detected (step S102; Yes), and if it is determined that the door 3 has been opened by checking the door signal (step S103; Yes), the CPU 42 performs an activation process (step S104). Specifically, the CPU 42 shifts to the active mode by receiving the supply of the clock frequency of the high-speed oscillation circuit from the clock generator 49.

  Next, the CPU 42 performs a power interruption process (step S105). Specifically, information being processed (hereinafter referred to as “main CPU information”) stored in the SRAM 43 and the register of the CPU 42 is saved in the backup area of the SRAM 43.

  Next, the CPU 42 outputs a one-pulse signal to the hall computer 70 as an opening / closing notification signal for notifying that the door 3 has been opened / closed (step S106). The hall computer 70 that has received the one-pulse signal acquires the current date and time from the clock module, and stores information indicating the date and time in the storage device as opening and closing date and time information.

  Next, the CPU 42 of the main board 4 shifts to the sleep mode by receiving the supply of the clock frequency of the low-speed oscillation circuit from the clock generator 49 (step S107), and ends the processing.

  On the other hand, if the activation signal is detected as a result of the monitoring in step S101 (step S102; Yes) and it is determined that the door 3 is closed (step S103; No), the CPU 42 performs the activation process (step S108), 1 pulse. A signal is output to the hall computer 70 (step S109).

  Next, the CPU 42 checks the main power signal (step S110). As a result, when it is determined that there is power supply from the main power supply device 8 (step S111; Yes), the CPU 42 performs a transition process to the normal game mode (step S112). Specifically, the game can be started by performing the initial setting of the CPU 42 and the SRAM 43 (when power interruption processing is performed in step S105, processing for restoring the saved main CPU information is performed). Transition to the state.

  If it is determined Yes in step S111 (that is, it is determined that there is power supply from the main power supply device 8), the gaming machine 1 and the external power supply are connected, but the power switch 8a is connected. A case where a person opens the door 3 and turns on the power switch 8a to close the door 3 in the off state.

  On the other hand, when determining that there is no supply of power from the main power supply device 8 (step S111; No), the CPU 42 shifts to the sleep mode (step S107) and ends the process.

  The above is the first fraud monitoring process. As described above, in the first fraud monitoring process, the main board 4 does not store the opening / closing date / time information, and only outputs a one-pulse signal for notifying that the door 3 has been opened / closed. This is because the main board 4 that controls the execution of the game is more likely to be illegally replaced than the sub board 5 that performs the production control, so that the monitoring result is more reliably stored in the external hall computer 70. It is because it can leave. Further, in this first fraud monitoring process, when the opening / closing of the door 3 is detected when the CPU 42 is operating in the sleep mode (step S102), the process proceeds to the active mode (steps S104, S108), and the hall computer Since one pulse signal is output to 70 (steps S106 and S109), it is possible to operate in the sleep mode until the opening / closing of the door 3 is detected, and power consumption can be saved. Further, when no power is supplied from the main power supply device 8 when the door 3 is closed (step S111; No), a 1-pulse signal is output in the active mode (step S109) to shift to the sleep mode (step S109). S107) The active mode can be set only when one pulse signal is output, and the power consumption of the backup power supply 45 can be saved. Further, when the door 3 is opened (step S103; Yes), after a 1-pulse signal is output in the active mode (step S106), to enter the sleep mode (step S107), the game is played with the door 3 opened. Can be prevented.

  In this first fraud monitoring process, a 1-pulse signal was output both when the door 3 was opened and when it was closed (steps S106 and S109), but the door 3 was closed. The output may be made in either case of the case or the case of being opened.

(Second fraud monitoring process performed by the main board)
Next, the second fraud monitoring process performed by the main board 4 will be described with reference to the flowchart shown in FIG.

  First, the CPU 42 of the main board 4 monitors a signal transmitted as an interrupt signal from the door opening / closing sensor 60 via the switching circuit 56 (step S201).

  If the activation signal is detected as a result of monitoring (step S202; Yes) and it is determined that the door 3 has been opened (step S203; Yes), the CPU 42 saves the main CPU information in the backup area of the SRAM 43, thereby Disconnect processing is performed (step S205).

  Next, the CPU 42 shifts to the sleep mode by receiving the supply of the clock frequency of the low-speed oscillation circuit from the clock generator 49 (step S207), and ends the processing.

  On the other hand, if the activation signal is detected as a result of monitoring (step S202; Yes) and it is determined that the door 3 is closed (step S203; No), the CPU 42 performs activation processing (step S208).

  Next, the CPU 42 checks the main power signal (step S210). As a result, when it is determined that there is power supplied from the main power supply device 8 (step S211; Yes), the CPU 42 performs a transition process to the normal game mode (step S212). Specifically, the game can be started by performing initial settings of the CPU 42 and the SRAM 43 (when power interruption processing is performed in step S205, processing for restoring the saved main CPU information is performed). Transition to the state.

  On the other hand, when determining that there is no power supply from the main power supply device 8 (step S211; No), the CPU 42 outputs a one-pulse signal to the hall computer 70 (step S213), and then shifts to the sleep mode (step S213). S207), the process is terminated.

  The above is the second fraud monitoring process. The second fraud monitoring process is different from the first fraud monitoring process in that the door 3 is opened and the door 3 is closed when power is supplied from the main power supply device 8. This is a point that one pulse signal is output only when the door 3 is closed when no power is supplied from the main power supply device 8 without outputting a pulse signal (step S213). Therefore, in the second fraud monitoring process, the opening / closing date / time information when the door 3 is opened / closed during the operation of the game store is not stored in the hall computer 70, and the employee of the game store stores the game machine 1. Since only the date and time when the door 3 is closed during transportation or when the amusement store is closed can be confirmed by the hall computer 70, it is easy to find fraud. If the door 3 is closed and no power is supplied from the main power supply 8 (step S211; No), the CPU 42 outputs a one-pulse signal to the hall computer 70 in the active mode (step S213). Therefore, since the mode is shifted to the sleep mode (step S207), the active mode can be set only when one pulse signal is output, and the power consumption of the backup power supply 45 can be saved.

  In the second fraud monitoring process, a one-pulse signal is output only when the door 3 is closed when no power is supplied from the main power supply 8. However, the power supply from the main power supply 8 is not supplied. One pulse signal may be output even when the door 3 is opened when there is not.

(Third fraud monitoring process performed by the sub-board)
Next, the third fraud monitoring process performed by the sub board 5 will be described with reference to the flowchart shown in FIG.

  The CPU 52 of the sub-board 5 monitors a signal transmitted as an interrupt signal from the door opening / closing sensor 60 via the switching circuit 56 (step S301).

  As a result of monitoring, an activation signal is detected (step S302; Yes), and when it is determined that the door 3 has been opened (step S303; Yes), the CPU 52 performs activation processing (step S304) and shifts to the active mode.

  Next, the CPU 52 performs a power interruption process (step S305). Specifically, information being processed (hereinafter referred to as “sub CPU information”) stored in the SRAM 53 and the register of the CPU 52 is saved in the backup area of the SRAM 53.

  Next, the CPU 52 acquires the current date and time from the clock module 57, and stores information indicating the date and time in the SRAM 53 as opening / closing date and time information (step S306).

  Next, the CPU 52 shifts to the sleep mode by receiving the supply of the clock frequency of the low-speed oscillation circuit from the clock generator 59 (step S307), and ends the processing.

  On the other hand, if the activation signal is detected as a result of monitoring (step S302; Yes) and it is determined that the door 3 is closed (step S303; No), the CPU 52 performs activation processing (step S308). Next, the CPU 52 acquires the current date and time from the clock module 57 and stores information indicating the date and time in the SRAM 53 as opening / closing date and time information (step S309).

  Next, the CPU 52 checks the main power signal (step S310). As a result, when it is determined that there is power supplied from the main power supply device 8 (step S311; Yes), the CPU 52 performs a transition process to the normal game mode (step S312). Specifically, the game can be started by performing initial settings of the CPU 52 and the SRAM 53 (when power interruption processing is performed in step S305, processing for restoring the saved sub CPU information is performed). Transition to the state.

  On the other hand, when determining that there is no power supply from the main power supply device 8 (step S311; No), the CPU 52 shifts to the sleep mode (step S307) and ends the process.

  The above is the third fraud monitoring process. In the third fraud monitoring process, the sub-board 5 performs only storage without outputting the opening / closing date / time information. This is because the sub-board 5 mainly controls the effect of the game, so that it is difficult to exchange or change the set value compared to the main board 4 that controls the game, and the opening / closing date and time information stored in the sub-board 5 This is because the possibility of being lost is low. In the third fraud monitoring process, when the opening / closing of the door 3 is detected when the CPU 52 is operating in the sleep mode (step S302), after the transition to the active mode (steps S304, S308), the opening / closing is performed. Since the date and time information is stored (steps S306 and S309), it is possible to operate in the sleep mode until the opening / closing of the door 3 is detected, and power consumption can be saved. Further, when the door 3 is closed and no power is supplied from the main power supply device 8 (step S311; No), after opening / closing date / time information is stored in the active mode (step S309), the sleep mode is entered. For this reason (step S307), the active mode can be entered only when opening / closing date and time information is stored, and the power consumption of the backup power supply 55 can be saved. In addition, when the door 3 is opened (step S303; Yes), after opening / closing date / time information is stored in the active mode (step S306), the game is played with the door 3 being opened in order to shift to the sleep mode (step S307). Can be prevented.

  In the third fraud monitoring process, the opening / closing date / time information is stored both when the door 3 is opened and when it is closed (steps S306 and S309), but the door 3 is closed. The opening / closing date / time information may be stored in one of the case and the case of being opened.

(Fourth fraud monitoring process performed by the sub-board)
Next, the fourth fraud monitoring process performed by the sub board 5 will be described with reference to the flowchart shown in FIG.

  First, the CPU 52 of the sub-board 5 monitors a signal transmitted as an interrupt signal from the door opening / closing sensor 60 via the switching circuit 56 (step S401).

  If the activation signal is detected as a result of the monitoring (step S402; Yes) and it is determined that the door 3 has been opened (step S403; Yes), the CPU 52 saves the sub CPU information in the backup area of the SRAM 53, thereby The disconnection process is performed (step S405).

  Next, the CPU 52 shifts to the sleep mode by receiving the supply of the clock frequency of the low-speed oscillation circuit from the clock generator 59 (step S407), and ends the processing.

  On the other hand, if the activation signal is detected as a result of monitoring (step S402; Yes) and it is determined that the door 3 is closed (step S403; No), the CPU 52 performs activation processing (step S408).

  Next, the CPU 52 checks the main power signal (step S410). As a result, when it is determined that there is power supplied from the main power supply device 8 (step S411; Yes), the CPU 52 performs a transition process to the normal game mode (step S412). Specifically, the game can be started by performing initial settings of the CPU 52 and the SRAM 53 (when power interruption processing is performed in step S405, processing for restoring the saved sub CPU information is performed). Transition to the state.

  On the other hand, when it is determined in step S411 that there is no power supply from the main power supply device 8 (step S411; No), the CPU 52 acquires the current date and time from the clock module 57, and displays information indicating the date and time as opening / closing date / time information. Is stored in the SRAM 53 (step S413). Thereafter, the CPU 52 shifts to the sleep mode (step S407) and ends the process.

  The above is the fourth fraud monitoring process. The fourth fraud monitoring process is different from the third fraud monitoring process in that the door 3 opens and closes when the door 3 is opened and when the door 3 is closed when power is supplied from the main power supply 8. The date and time information is not stored, the power is not supplied from the main power supply 8, and the opening and closing date and time information is stored only when the door 3 is closed (step S413). Therefore, in the fourth fraud monitoring process, the opening / closing date / time information is not stored when the door 3 is opened / closed while the game shop is in operation, and the employee of the game shop is transporting the gaming machine 1 or closing the game shop. Only the date and time when the door 3 is closed in the middle can be confirmed on the liquid crystal display 91 of the image display unit 9, so that it is easy to find an illegal act. In the fourth fraud monitoring process, when the door 3 is closed and no power is supplied from the main power supply device 8 (step S411; No), the CPU 52 stores the opening / closing date and time information in the active mode. After that (step S413), since the mode is shifted to the sleep mode (step S407), the active mode can be set only when the opening / closing date and time information is stored, and the power consumption of the backup power supply 55 can be saved.

  In the fourth fraud monitoring process, the opening / closing date / time information is stored only when the door 3 is closed when there is no supply of power from the main power supply 8, but the supply of power from the main power supply 8 is not performed. The opening / closing date / time information may be stored even when the door 3 is opened when there is not.

  As described above, when the door 3 is opened / closed, the CPU 42 of the main board 4 outputs an open / close notification signal for notifying that the door 3 has been opened / closed to the hall computer 70 in the active mode. Since the CPU 52 of FIG. 5 stores the opening / closing date / time information in the SRAM 53 in the active mode, even if one of the main board 4 and the sub board 5 is illegally exchanged, the door opening / closing is monitored on the board that has not been exchanged. The monitoring result can be recorded (that is, the opening / closing date / time information is stored in the hall computer 70 of the output destination, or the opening / closing date / time information is stored in the SRAM 53). Further, since the main board 4 and the sub board 5 can be operated in the sleep mode except when one pulse signal is output or when opening / closing date / time information is stored and when a game is executed, power consumption can be saved.

  In addition, since the gaming machine 1 includes backup power sources 45 and 55 that supply power when power is not supplied from the main power supply device 8, the gaming machine 1 is not connected to an external power source during transportation. The opening and closing of the door 3 can be monitored even when the power switch of the gaming machine 1 is turned off, for example, when the game store is closed. When there is no supply of power from the main power supply device 8, the CPUs 42 and 52 operate in the sleep mode, so that the backup power sources 45 and 55 can be made longer and monitoring can be continued for a long time. Further, since the CPUs 42 and 52 of the gaming machine 1 shift to the sleep mode when the door 3 is opened, it is possible to prevent an unauthorized game from being performed.
