DISHONEST ACT DETECTING CIRCUIT IN GAME MACHINE

摘要

PURPOSE:To exactly detect such a dishonest act as medal thread suspension. CONSTITUTION:On the upstream side and the downstream side of a diagonal line of a selector, sensors SS1, SS2 are provided, and a timer 11, a signal generating circuit 12 and an OR gate 13 are provided. When the timer 11 is operated by an output signal S1 of the sensor SS1 and an output signal S2 of the sensor SS2 is generated after time-up of the timer 11, the signal generating circuit 12 generates a pseudo signal S4 of longer pulse width than a prescribed value. Accordingly, pulse width of a detecting signal S5 in this case becomes longer than the prescribed value, and medal thread suspension can be detected.
