<p><P>PROBLEM TO BE SOLVED: To provide a game machine, detecting fraudulentness to a sensor of a discharge device without a large-scale device. <P>SOLUTION: This game machine includes the discharge device (330) for discharging a required number of game balls based on the establishment of a predetermined discharge condition. The game machine includes a detecting sensor (112) and a fraudulentness detecting sensor (113) which are respectively formed of a magnetic proximity sensor capable of detecting a discharged game ball, and a monitoring means (210) for monitoring fraudulentness based on the input of the fraudulentness detecting sensor. The fraudulentness detecting sensor is disposed in a predetermined part of the game machine in the state of holding the state similar to that in the case where the detecting sensor detects a game ball, and the monitoring means is configured to detect fraudulentness when the non-detecting state of the game ball is input from the fraudulentness detecting sensor. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
