Description of the Related Art A gaming machine that detects a winning ball or a gaming ball paid out when lending a ball is known. In such a gaming machine, there has been a case in which an illegal act of illegally discharging a gaming ball by irradiating a radio wave toward the gaming machine is performed. Specifically, for example, when an electromagnetic induction proximity sensor (discharge sensor) is irradiated with a radio wave when a payout condition is satisfied, the ball is passed though the detection ball of the sensor passes through the sensor. A state of outputting a signal indicating that the signal does not pass is illegally formed.

  In such a case, the payout device (discharge device) does not perform the specified number of payouts, and therefore, by repeating the retry operation, game balls are paid out one after another. The above game balls will be paid out illegally. Therefore, in order to prevent such injustice, a technique for providing a shield that blocks radio waves irradiated from the outside has been proposed (see, for example, Patent Document 1 or Patent Document 2).

  Further, as shown in FIG. 8, the pachinko gaming machine 1 includes a control system centered on the game control device 49, and is configured to control the game progress by the game control device 49. The game control device 49 is a microprocessor that controls game control, a ROM that stores a program for game control, etc., and a RAM that is used as a work area during game control, an input interface, an output interface, an inspection device connection terminal, etc. It is composed of Then, it receives signals from various detection devices (special drawing start sensor 91, universal drawing start sensor 92, count sensor 93, winning port sensor 94, overflow switch 95, ball break switch 96, frame opening switch 97), and fluctuates. Various processes, such as execution of a display game (a common figure change display game, a special figure change display game), generation | occurrence | production of a special game state (big hit state), alert | report to a player, etc. are performed. Furthermore, in addition to various control devices (display control device 47, payout control device 25) serving as sub-control devices, the general-purpose display device 100, the special-purpose display device 101, and the ordinary electric accessory (opening / closing member) 40a of the start winning port 40.

  The payout control device 25 is a control device that functions as a monitoring unit in the present invention, and is used as a microprocessor that controls payout control, a ROM that stores a program for payout control, and a work area during payout control. RAM, an input interface, an output interface, an inspection device connection terminal, and the like. And various detection devices (radio wave detection sensor 71, electromagnetic induction proximity sensor 64, error release switch 106, tax rate setting switch 107, rental charge setting switch 108) not connected to game control device 49, and game control device 49 receives a signal from a detection device (overflow switch 95, out-of-ball switch 96) also connected to 49, and performs processing related to paying out a game ball such as ball rental or prize ball discharge. Further, a command signal is transmitted to the payout motor 66, the launch control device 26, the error number display 109, the tax rate display 110, and the rental charge display 111, and processing information related to payout control is transmitted to the game control device 49. To do.

  When the pachinko gaming machine 1 is equipped with the radio wave detection unit 70 and the payout control device 25 having such a configuration and the power is turned on, the detection dummy body 72 is detected by the detection unit 71a of the radio wave detection sensor 71 under normal conditions. A detection signal indicating that the detected dummy body 72 is detected is sent out, and this detection signal is received by the dispensing control device 25. At this time, since the movement of the detected dummy body 72 is restricted by the movement restricting portion 84 and the center P of the detected dummy body (game ball) 72 is positioned on the central axis L of the through hole 71b, The detection dummy body 72 can be held at a position that can be reliably detected by the detection unit 71a. Further, it is possible to prevent the inconvenience of the detected dummy body 72 moving around inside the through hole 71b and colliding with the detection unit 71a, and further the inconvenience of the detection unit 71a of the radio wave detection sensor 71 being damaged. Further, since the air gap 82 of the radio wave detection unit 70 and the wiring outlet 85 are communicated with each other, heat generated from the radio wave detection sensor 71 is passed through the wiring outlet 85 and released to the outside of the radio wave detection unit 70. And the inconvenience that the radio wave detection sensor 71 is damaged by heat can be prevented. Even if the radio wave detection sensor 71 continuously sends out detection signals, in other words, there is a possibility that the radio wave detection sensor 71 continuously generates heat, the use environment temperature of the radio wave detection sensor 71 is the allowable temperature. And the stability of the detection operation of the radio wave detection sensor 71 can be ensured.

  Then, when a game is executed or when a ball lending operation is performed, an unauthorized person tries to cheat the count of game balls in the payout device 57, and the electromagnetic induction proximity sensor 64 of the ball payout unit 22 has a certain amount. If the radio wave (illegal radio wave) is illegally irradiated at a specific frequency, even if the game ball passes through the through hole 64b of the electromagnetic induction proximity sensor 64, the voltage change due to the magnetic flux change of the detection unit 64a is suppressed. The counting of game balls will be prevented. If the payout process is continued in this state, the payout control device 25 drives the payout device 57 until the specified number of game balls are counted, and the number of fraudulent players playing game balls greater than the specified number. I would get it fraudulently.

  However, in the radio wave detection unit 70, the radio wave detection sensor 71 housed in the housing member 73 is disposed in the vicinity of the electromagnetic induction proximity sensor 64 and in the same posture as the electromagnetic induction proximity sensor 64. Therefore, the unauthorized radio wave is also applied to the detection unit 71 a of the radio wave detection sensor 71. Then, in spite of the fact that the detected dummy body 72 is disposed in the through hole 71b of the radio wave detection sensor 71, the voltage change caused by the magnetic flux change of the detection unit 71a is suppressed, thereby sending the detection signal. Stop and send a non-detection signal (non-detection signal meaning that the detected dummy 72 is not detected) to the payout control device 25. Then, the payout control device 25 determines that the unauthorized radio wave is applied to the radio wave detection unit 70 and the electromagnetic induction proximity sensor 64 based on the reception of the non-detection signal, and performs the payout operation of the game ball in the payout device 57. Processing such as stopping is performed. Therefore, the illegal act of illuminating the electromagnetic induction proximity sensor 64 with an unauthorized radio wave can be detected without requiring a large structure, and can be reliably detected by monitoring performed by the dispensing control device 25. it can. In addition, since the radio wave detection unit 70 is provided between the game board storage frame 5 and the ball payout unit 22, it is possible to avoid the inconvenience that the radio wave detection unit 70 is exposed on the front side or the back side of the pachinko gaming machine 1. It is possible to suppress an illegal act of crafting or damaging the detection sensor 71.

  Further, the radio wave detection sensor 71 (radio wave detection unit 70) is positioned on the game board 5 side, in other words, on the player side relative to the electromagnetic induction type proximity sensor 64, and an unauthorized person is located in front of the pachinko gaming machine 1. The radio wave detection sensor 71 can be brought closer to the operating source of the illegal radio wave to be operated than the radio wave induction proximity sensor 64. Accordingly, the radio wave detection sensor 71 is more susceptible to receiving an illegal radio wave than the radio wave induction proximity sensor 64, and the detection sensitivity of the radio wave detection sensor 71 can be improved.

  Next, the control for realizing the above-described radio wave detection operation will be specifically described based on the flowcharts of FIGS. First, based on the flowcharts of FIGS. 9 and 10, main processing that the payout control device 25 starts executing when the pachinko gaming machine 1 is powered on or restored from a power failure will be described. In the main processing, first, setting of prohibition of timer interruption (S1), setting of each interrupt mode (S2) performed at a predetermined time period (for example, 1 millisecond period), and permission of access to the RAM of the payout control device 25 are performed. (S3) The CPU peripheral device initial setting (S4) and stack pointer setting (S5) of the payout control device 25 are performed.

  Further, it is determined whether or not the RAM clear switch 113 (see FIG. 8) provided in the power supply device 27 is turned on to perform an operation for initializing the RAM of the payout control device 25 (S6). If it is determined that 113 is not ON, whether or not the power is restored when the power failure is restored is determined by determining whether or not the power failure restoration information indicating that the power is restored from the power failure is set in the RAM. Is determined (S7). If it is determined that the power is turned on when the power failure is restored, it is checked whether the checksum is normal in order to determine whether the data stored in the RAM is corrupted (S8, S9). Specifically, it is determined whether or not the checksum of the data stored in the RAM when a power failure occurs matches the checksum of the data currently stored in the RAM. When it is determined that the checksum is normal, that is, when it is determined that the data stored in the RAM is normal, the power failure recovery process is executed and the initial value at the time of power failure recovery is stored in the RAM. Set (S10).

  On the other hand, if it is determined in step S6 that the RAM clear switch 113 is ON, it is determined in step S7 that the power is not turned on when the power failure is restored, or the checksum is abnormal in step S9. If determined, after clearing the data stored in all the RAMs used, the initial value when the power is turned on to the RAM and the lending amount per gaming ball set by the lending fee setting switch 108 are obtained. After setting, the RAM of the payout control device 25 is initialized (S11, S12, S13).

  If the RAM is initialized or the initial value at the time of power failure recovery is set in the RAM, a PRDY signal is output to the card unit 17 to notify that the game ball can be lent (S14). And CTC (Counter Timer Circuit), which is a timer for measuring time, is set (S15), and the timer interrupt prohibited in step S1 is permitted (S16).

  If the timer interrupt permission is set, it is determined whether or not the card unit 17 is connected to the payout control device 25 (S17). If it is determined that the card unit 17 is connected, the launch control device 26 is connected to the game ball. The state is set to allow launching (launching permitted state) (S18), and if it is determined that it is not connected, the firing control device 26 is set to a state not allowing launching of the game ball (launching not permitted state). (S19). If the launch control device 26 is set to either the launch permitted state or the launch non-permitted state, the payout control mode is acquired (S20), and processing is performed according to the acquired payout control mode (mode 0, mode 1, mode 2). Is branched (S21). In the case of mode 0, a payout excessive error monitoring process for monitoring whether or not game balls are being paid out excessively is executed (S22), and in order to actually start paying out game balls, A payout device control start determination process is executed (S23). In the case of mode 1, a prize ball control process for setting the number of game balls to be paid out as a prize ball is executed (S24), a payout control process for controlling the payout motor 66 is executed, and a game ball as a prize ball is executed. Payout (S25). In the case of mode 2, a ball lending control process for setting the number of game balls to be paid out as a lending ball is executed (S26), a payout control process for controlling the payout motor 66 is executed, and the game ball as a lending ball is executed. Payout (S25).

  If the processing corresponding to each mode is executed, an error notification editing process (S27) for editing the notification of an error that has occurred during the game ball payout operation, and the electromagnetic induction type proximity sensor detects illegal radio waves during the game ball payout operation. 64 and a fraud monitoring process (S28) for monitoring whether or not the electromagnetic detection unit is irradiated. The fraud monitoring process will be described later in detail. Further, the content of the power failure inspection area in the RAM of the payout control device 25 is acquired (S29), and it is determined whether or not a power failure has occurred based on this content (S30). If it is determined that a power failure has not occurred, the process returns to step S17. If it is determined that a power failure has occurred, the power failure processing (interrupt disabled setting (S31), all Output port OFF (S32), power failure recovery information stored in RAM (S33), checksum calculation and storage of data in RAM before power supply to RAM is cut off (S34), access to RAM prohibited (S35) ) And wait until the power of the pachinko gaming machine 1 is turned off.

  Further, when the timer interrupt is permitted in the main process, the payout control device 25 executes a timer interrupt process for every predetermined time period. The timer interrupt process will be described with reference to the flowchart shown in FIG. 11. First, the AF register of the CPU of the payout control device 25 is saved (S41), and an external interrupt which is a forced interrupt signal output when a power failure occurs. Only the interrupt is permitted (S42), and after the end of the timer interrupt process is declared, the interrupt is permitted (S43, S44).

  Then, the BC register, DE register, and HL register of the CPU of the payout control device 25 are saved (S45), and output processing is executed (S46). In the output process, a drive signal is output to the payout motor 66, the firing control device 26, the error number display 109, and the like. If the output process is executed, the input process is executed (S47). In the input processing, processing such as chattering removal is performed on the signal input from the electromagnetic induction proximity sensor 64, the radio wave detection sensor 71, the ball break switch 96, the overflow switch 95, the signal input from the card unit 17, and the like. Confirm the input information.

  After executing the input processing, timer update processing (S48), request monitoring processing (S49), input monitoring processing (S50), payout unit output editing processing (S51), and external information output editing processing (S52) are executed. In the timer update process, various timers are updated, and in the request monitoring process, various commands and signals received by the payout control device 25 are analyzed to monitor whether the BRDY signal is output from the card unit 17. Further, in the input monitoring process, based on the signal from the card unit 17, it is monitored whether or not the card unit 17 and the payout control device 25 are connected, and the signal input from the electromagnetic induction proximity sensor 64 is monitored. Based on this, it is monitored whether or not a number of game balls to be paid out have been paid out. Furthermore, in the payout unit output editing process, output information is edited to control the payout motor 66, and in the external information output editing process, information relating to the pachinko gaming machine 1 is collected from the information collection terminal, the game hall internal management device, etc. (Neither is shown in the figure). When the external information output editing process has been executed, the BC register, DE register and HL register are restored (S53), the external interrupt and timer interrupt are enabled (S54), the AF register is restored (S55), and the timer is reset. End the interrupt process and return to the main process.

Next, the fraud monitoring process will be described based on the flowchart shown in FIG.
In the fraud monitoring process, first, it is determined whether or not the payout device 57 is performing the operation of driving the payout motor 66 to pay out the game ball (S61). It is determined whether or not the detected dummy body 72 is detected (S62). If the detected dummy 72 is not detected (in other words, the radio wave detection sensor 71 is sending a non-detection signal), 1 is added to the fraud counter (S63). It is determined whether or not the fraud counter is greater than or equal to a preset fraud determination value (eg, “5”) (S64). If it is equal to or greater than the fraud determination value (in other words, if the non-detection signal is continuously received for a time during which the fraud counter becomes the fraud determination value (non-detection period)), the radio wave detection sensor 71 and the electromagnetic induction It is determined that unauthorized radio waves are irradiated to the proximity sensor 64, an unauthorized flag is set (S65), and the unauthorized monitoring process is terminated. If it is less than the fraud determination value, the fraud monitoring process is terminated without setting the fraud flag.

  Further, when the payout operation is not performed in step S61, or in step S62, the radio wave detection sensor 71 detects the detected dummy body 72 (in other words, the radio wave detection sensor 71 sends a detection signal). In this case, the fraud counter is cleared and set to 0 (S66), the fraud flag is reset (S67), and the fraud monitoring process is terminated.

  When returning to the execution of the main process after the end of the fraud monitoring process, the fraud flag is checked in the payout control process performed in the main process. If the fraud flag is set, it means that the radio wave detection sensor 71 and the electromagnetic induction proximity sensor 64 are irradiated with illegal radio waves, and therefore control for stopping the payout operation is executed. As a result, it is possible to prevent a predetermined number or more of game balls from being paid out due to fraud. In the payout operation, a payout unit operation in which a predetermined unit payout amount is paid out is set, and a plurality of game balls are paid out by executing this payout unit operation a plurality of times. . When the control for stopping the payout operation is executed, the payout unit operation that is scheduled to be performed after the stop control is executed is canceled, and the payout unit operation that is being executed when the stop control is executed For, pay out all the unit payouts without stopping on the way.

  Further, in the fraud monitoring process, based on the fact that the non-detection signal has been continuously received for a preset non-detection period or more, the radio wave detection unit 70 and the electromagnetic induction proximity sensor 64 are irradiated. Since the determination is made, the payout control device 25, which is a monitoring means, receives the same signal as the non-detection signal based on internal noise generated by the game ball that has been paid out or external noise from the outside of the pachinko gaming machine 1. Even if it does, it can prevent misjudging that the unauthorized radio wave was irradiated.

  In the above embodiment, the payout control device 25 can receive only the detection signal and the non-detection signal from the radio wave detection sensor 71. However, the present invention is not limited to this. For example, in the second embodiment shown in FIGS. 13 and 14, the payout control device 25 is a signal that means that the radio wave detection sensor 71 is abnormal, in particular, that the signal wiring 75 of the radio wave detection sensor 71 is disconnected or short-circuited. Is configured to be able to receive. More specifically, as shown in FIGS. 13A and 13B, the radio wave detection sensor 71 sets the detection signal voltage higher than the non-detection signal voltage, and further drives the radio wave detection sensor 71. Therefore, it is set lower than the power supply voltage (operating voltage) applied. Specifically, the voltage of the detection signal is 11.5V, the voltage of the non-detection signal is 6V, and the power supply voltage is 12V.

  Further, as shown in FIG. 14, an output state determination circuit 115 is interposed between the payout control device 25 and the radio wave detection sensor 71 (specifically, the signal wiring 75 of the radio wave detection sensor 71), and the output state determination is performed. The circuit 115 is configured to determine the state of the radio wave detection sensor 71 based on the voltage of a signal received (input) from the radio wave detection sensor 71 side. Specifically, when a signal of 11.5 V is received from the radio wave detection sensor 71 side, the output state determination circuit 115 determines that this signal is a detection signal and sends the detection signal from the radio wave detection sensor 71. This is transmitted to the payout control device 25. Further, when a 6V signal is received from the radio wave detection sensor 71 side, this signal is determined as a non-detection signal, and the fact that the non-detection signal is transmitted from the radio wave detection sensor 71 is sent to the dispensing control device 25. Send. Further, when receiving a signal of 12 V from the radio wave detection sensor 71 side, in other words, the same voltage as the power supply voltage of the radio wave detection sensor 71, the signal wiring 75 or the circuit board of the radio wave detection sensor 71 is disconnected. It determines with a thing (refer Fig.13 (a)), and transmits that the disconnection generate | occur | produced to the payout control apparatus 25. FIG. When a signal of 0 V is received from the radio wave detection sensor 71 side, that is, when no signal is received, it is determined that the signal wiring 75 or the circuit board of the radio wave detection sensor 71 is short-circuited. (Refer to FIG. 13B), the fact that a short circuit has occurred is transmitted to the dispensing control device 25. The output state determination circuit 115 is preferably mounted on a relay board that relays the payout control device 25 and the radio wave detection sensor 71, but may be mounted on a payout control board constituting the payout control device 25. (Neither shown).

  Further, as shown in FIG. 14, an electromagnetic induction proximity sensor 64 having the same structure and performance as the radio wave detection sensor 71 is also connected to the input side of the output state determination circuit 115, and the output state determination circuit 115 is connected to the output state determination circuit 115. The state of the electromagnetic induction proximity sensor 64 is determined based on the voltage of a signal received (input) from the electromagnetic induction proximity sensor 64 side. Specifically, the electromagnetic induction type proximity sensor 64 sets the voltage of the passing signal that means that the game ball has passed higher than the voltage of the non-passing signal that means that the game ball has not passed, Furthermore, it is set lower than the power supply voltage (operation voltage) applied to drive the electromagnetic induction proximity sensor 64. Specifically, the voltage of the passing signal is 11.5V, the voltage of the non-passing signal is 6V, and the power supply voltage is 12V. Further, when the output state determination circuit 115 receives a signal of 11.5 V from the electromagnetic induction proximity sensor 64 side, the output state determination circuit 115 determines that this signal is a passing signal, and the electromagnetic induction proximity sensor 64 pays out from the sprocket 63. The fact that the passing of the played game ball is detected is transmitted to the payout control device 25. Further, when a 6V signal is received from the electromagnetic induction proximity sensor 64 side, this signal is determined as a non-passing signal, and payout control is performed to indicate that the electromagnetic induction proximity sensor 64 has not detected the passing of the game ball. Transmit to device 25. Further, when a signal of 12V from the electromagnetic induction proximity sensor 64 side, in other words, a signal having the same voltage as the power supply voltage of the electromagnetic induction proximity sensor 64 is received, the signal wiring of the electromagnetic induction proximity sensor 64 or the electromagnetic induction proximity sensor It is determined that 64 circuit boards are disconnected, and the fact that the disconnection has occurred is transmitted to the dispensing control device 25. When a signal of 0 V is received from the electromagnetic induction proximity sensor 64 side, in other words, when neither signal is received, the signal wiring of the electromagnetic induction proximity sensor 64 or the circuit board of the electromagnetic induction proximity sensor 64 is It determines with having short-circuited, and transmits that the short circuit had occurred to the payout control apparatus 25.

  In the second embodiment having such a configuration, in the fraud monitoring process, as shown in FIG. 15, first, the dispensing device 57 is notified that a disconnection or a short circuit related to the radio wave detection sensor 71 has occurred from the output state determination circuit 115. (S71), if a disconnection or a short circuit has occurred, a disconnection / short circuit flag is set (S72), and if a disconnection or a short circuit has not occurred, a disconnection / short circuit has occurred. The flag is reset (S73). If the disconnection / short circuit flag is set or reset, it is determined whether or not the payout device 57 is driving the payout motor 66 to pay out the game ball (S74). Then, it is determined whether or not the radio wave detection sensor 71 detects the detected dummy body 72 (S75). If the detected dummy 72 is not detected (in other words, the radio wave detection sensor 71 is sending a non-detection signal), 1 is added to the counter for fraud (S76). It is determined whether or not the fraud counter is greater than or equal to a preset fraud determination value (eg, “5”) (S77). If it is greater than or equal to the fraud determination value, in other words, if the non-detection signal is continuously received for a period of time during which the fraud counter becomes the fraud determination value (non-detection period), the radio wave detection sensor 71 and the electromagnetic induction type It is determined that unauthorized radio waves are irradiated on the proximity sensor 64, an unauthorized flag is set (S78), and the unauthorized monitoring process is terminated. If it is less than the fraud determination value, the fraud monitoring process is terminated without setting the fraud flag.

  Further, when the payout operation is not performed in step S74, or in step S75, the radio wave detection sensor 71 detects the detected dummy body 72 (in other words, the radio wave detection sensor 71 transmits a detection signal). In this case, the fraud counter is cleared and set to 0 (S79), the fraud flag is reset (S80), and the fraud monitoring process is terminated.

  When returning to the execution of the main process after the end of the fraud monitoring process, the disconnection / short circuit flag and the fraud flag are checked in the payout control process performed in the main process. If the fraud flag is set, it means that the radio wave detection sensor 71 and the electromagnetic induction proximity sensor 64 are irradiated with an improper radio wave. If the disconnection / short circuit flag is set, This means that the detection cannot be executed. Therefore, if at least one of the illegal flag and the disconnection / short-circuit flag is set, control for stopping the payout operation is executed. As a result, it is possible to prevent a predetermined number or more of game balls from being paid out due to fraud.

  By the way, in the said embodiment, although the payout apparatus 57 was comprised including the sprocket 63, the payout motor 66, and the electromagnetic induction type proximity sensor 64, this invention is not limited to this. For example, the sprocket 63 and the payout motor 66 may constitute a payout mechanism, and the electromagnetic induction proximity sensor 64 may be arranged separately from the payout mechanism so as to face the payout flow path. Then, a radio wave detection unit 70 is disposed between the payout mechanism section and the game board storage frame 5 or between the payout flow path and the game board storage frame 5, and the radio wave detection sensor 71 is replaced with an electromagnetic induction proximity sensor. It may be positioned in the vicinity and may have the same posture as the electromagnetic induction proximity sensor. If the radio wave detection unit 70 is arranged in this way and the radio wave detection sensor 71 (radio wave detection unit 70) is located on the game board 5 side, in other words, on the player side relative to the electromagnetic induction proximity sensor 64, a pachinko gaming machine The radio wave detection sensor 71 can be brought closer to the source of the illegal radio wave operated by the fraudster in front of the radio wave induction proximity sensor 64. Accordingly, the radio wave detection sensor 71 is more susceptible to receiving an illegal radio wave than the radio wave induction proximity sensor 64, and the detection sensitivity of the radio wave detection sensor 71 can be improved.

  In the above embodiment, the payout control device 25 is a monitoring means in the present invention, and the payout control device 25 receives a signal from the radio wave detection sensor 71 and monitors whether or not an illegal radio wave is irradiated. However, the present invention is not limited to this. For example, a game control device 49 is adopted as a monitoring means and a radio wave detection sensor 71 is connected, and the game control device 49 receives a signal from the radio wave detection sensor 71 and monitors whether an illegal radio wave is irradiated. You may comprise as follows. Further, in the fraud monitoring process in the above embodiment, when the payout device 57 is executing a game ball payout operation, whether or not a non-detection signal is received from the radio wave detection sensor 71 (in other words, an illegal radio wave). However, the present invention is not limited to this. For example, it may be determined whether or not a non-detection signal is received from the radio wave detection sensor 71 regardless of whether or not a game ball payout operation is being executed. In the above embodiment, a through hole through which a game ball can pass is opened in the electromagnetic induction proximity sensor 64 and the radio wave detection sensor 71, but the present invention is not limited to this. In short, any electromagnetic induction type sensor capable of detecting a game ball or a detected dummy body in a non-contact manner by the detection unit may be used. For example, a so-called flat type proximity sensor that does not have a through hole may be used. .

  In the above embodiment, a pachinko gaming machine, which is a typical gaming machine, has been described as an example. However, the present invention is not limited thereto, and a gaming board storage frame for storing a gaming board is provided, and the gaming board storage frame is provided. On the back side of the payout mechanism, a payout mechanism portion that can pay out game balls, a payout passage through which the game balls paid out from the payout mechanism portion flow down, and a count for game balls flowing down through the payout passage Any gaming machine provided with an electromagnetic induction proximity sensor may be used. For example, it may be a gaming machine such as an enclosed ball pachinko machine, an arrangement ball gaming machine, or a sparrow ball gaming machine.
