PROBLEM TO BE SOLVED: To provide a token game machine capable of detecting the fraudulence using a deceptive implement to actively change the physical quantity corresponding to a sensor to detect passage of tokens. SOLUTION: A passing object detector 41 to be brought into mechanically contact with the deceptive implement which blinks light to deceive the sensor to detect passage of tokens M is mounted on the upstream side of the sensor in a token pathway 21. Then, the deceptive implement inserted into a token slot 11 dislodges a contact piece 41B of the passing object detector 41, so that the contact piece 41B is moved. The movement of the passing object detector 41 is detected by a movement detection sensor 42, and a movement signal output from the movement detection sensor 42 is monitored. In this way, the fraudulence using the deceptive implement can be securely detected. COPYRIGHT: (C)2009,JPO&INPIT
