  However, in the above-described conventional configuration, an illegal act of the piano wire is prevented by adopting a structure in which it is difficult for the piano wire to enter the inside through the gap between the glass unit and the frame body. Therefore, if a player performs a destructive action such as forcibly widening the gap between the glass unit and the frame body or making a hole in the frame body, the player will be prevented from entering the piano wire. It is not possible to prevent an illegal act such that the game nail is arbitrarily adjusted to a state advantageous to the player. In addition, if an employee of a store (hall) where a pachinko machine is installed does not notice the execution of the destructive action, the fraudulent action may be caused by the broken frame body, an improperly adjusted game nail or a prize. Since employees and others find a pachinko machine that has an extremely high rate compared to others, it can be discovered afterwards, so there is a possibility that fraudulent acts will be repeated after destructive acts.

Note that the detection sensitivity (resistance value of the variable resistor) of the contact detection circuit 60 reliably detects that the human body is in direct contact with the game nail 63 and indirectly through the conductive member, and the game The value is set in advance so as not to detect that the ball has come into contact with the game nail 63.

[Injustice detection system]
The fraud detection system according to the present embodiment includes the CPU 13a of the main control device 13, the contact detection circuit 60, the lock detection sensor 66, and the notification means.

  The lock detection sensor 66 outputs a door closing detection signal to the contact detection circuit 60 when the lock lock 25 is locked, and the contact detection circuit 60 has received the door closing detection signal from the lock detection sensor 66. As a condition, a contact detection signal is output to the main controller 13 when the human body directly contacts the game nail 63 or indirectly contacts through a conductive member such as a piano wire.

  When receiving the contact detection signal from the contact detection circuit 60, the CPU 13a of the main control device 13 outputs a fraud detection signal to the sub-control device 14, the payout control device 52, and the external centralized management device 48.

  When the lamp control device 14b and the voice control device 14c of the sub-control device 14 receive the fraud detection signal, the lamp control device 14b and the voice control device 14c execute a notification process for notifying a hall employee that a fraudulent act may be performed. . This notification processing includes lighting processing of the fraud notification lamp 67 and output processing from the speaker 30 of an alarm sound that informs execution of fraud. Instead of or in addition to the lighting process of the fraud notification lamp 67, a lamp lighting or blinking process that notifies the execution of the fraudulent act in the frame door-related lighting 29 may be performed.

  Further, when the payout control device 52 receives the fraud detection signal, the payout control device 52 executes payout stop processing for temporarily stopping payout of the prize ball based on the fraudulent act. In the payout stop process, the game ball payout device 15 receives a signal instructing to stop paying out the game balls from the payout control device 52, and temporarily stops payout of the game balls.

  According to such a fraud detection system, the player makes the game nail 63 advantageous by allowing the conductive member 68 such as a piano wire to enter the game board 7 from the gap between the main body member 5 and the door 8 with the ball tray. If an attempt is made to arbitrarily adjust the state, when the human body comes into contact with the game nail 63 via the conductive member 68, the contact detection circuit 60 outputs a contact detection signal, whereby the fraud notification lamp 67 is turned on. An alarm sound that informs the execution of fraud is output, and the central control device 48 receives a fraud detection signal. Therefore, the employee of the hall can know the execution of the illegal act by the player at an early stage, and can prevent the illegal act.

  Also, when a player performs a destructive action such as forcibly expanding the gap between the main body member 5 and the door 8 with the ball tray or making a hole in the main body member 5, the human body is directly or When the game nail 63 is indirectly contacted via the conductive member 68, the contact detection circuit 60 outputs a contact detection signal, so that the employee of the hall knows early and surely the execution of the cheating by the player. And fraud can be prevented in advance.

  In addition, when a trouble such as a ball clogging occurs during the game by the player, and the employee unlocks the lock lock 25 and opens the door 8 with the ball tray in order to solve such trouble, Even if the door closing detection signal is not output from the detection sensor 66 and the employee directly contacts the game nail 63 or indirectly through the conductive member 68, the contact detection circuit 60 does not output the contact detection signal. . Therefore, it is possible to reliably avoid erroneous detection that an illegal act is being performed during work by an employee for solving a problem during the game.

  In addition, since the conductive sheet 65 is arranged between the plurality of plate members 64, even if the inclination of the game nail 63 is changed by the nail adjustment, each game nail 63 and the conductive sheet 65 are not in contact with each other. Hard to be in contact. Therefore, contact detection by the contact detection circuit 60 can be reliably performed.

  Further, since the guide rail 32 and the game ball regulating rail 33 are electrically connected to the front conductive sheet 65 via the fixed nail 69 driven into the game board 7, the human body is connected via the conductive member 68. Even when the guide rail 32 or the game ball regulation rail 33 is touched, the fraud notification lamp 67 is turned on, an alarm sound is sent to notify the execution of the fraud, and the central control device 48 receives the fraud detection signal. Therefore, the employee can know the execution of cheating earlier.

  In addition, since the conductive sheets 65 are arranged between both the plurality of plate members 64 and on the front surface of the foremost front plate member 64a, each game nail 63 is in contact with the conductive sheet 65 at two positions in the front and rear. Therefore, the contact state between each game nail 63 and the conductive sheet 65 is more reliably maintained, and the contact detection by the contact detection circuit 60 can be more reliably performed.

  Furthermore, this fraud detection system arranges the conductive sheet 65 between at least one of the plurality of plate members 64 or on the front surface of the front plate member 64a, and electrically connects the contact detection circuit 60 to the conductive sheet 65. Since this is a simple configuration, an increase in manufacturing man-hours and costs can be suppressed.

  Instead of or in addition to the lock detection sensor 66, a switch (not shown) for stopping the execution of contact detection by the contact detection circuit 60, for example, a game area other than the game area 31 in the game board 7 is used. It may be provided in a place where the inside player cannot touch.
