PROBLEM TO BE SOLVED: To provide a Pachinko machine capable of surely detecting a fraud using a magnet. SOLUTION: A detection waveform obtained by detecting in a switch input processing repeatedly executed for every 4 ms forcibly generates aliasing where the waveform of a pulse wave for energizing a coil of a ball retention-section solenoid 54 cannot be retained rightly. Thereby, a main control board 68 samples a detection signal from a magnetic detection switch MS in a switching processing, creates a history of the detection signal from the magnetic detection switch MS in a magnetic detection switch history creation processing and determines whether it is an ON signal or an ON/OFF signal from the magnetic detection switch MS based on the created history so as to discriminate the magnetism generated by a magnet by a fraud using the magnet from the magnetism generated by energization of the coil of the ball retention-section solenoid 54. This Pachinko machine can surely detect the fraud by the magnet. COPYRIGHT: (C)2010,JPO&INPIT |
