Winning a prize sphere detector and winning a prize detection system

摘要

PURPOSE:To carry out electric detection of a prize winning pinball in many prize winning openings in simple wiring by providing a modulation circuit for modulating and outputting a pulse signal showing detection of a prize winning pinball. CONSTITUTION:A prize winning detector 30b includes a frame body 37 having a prize winning pinball passing opening 36 formed on a part thereof, and incorporates an electronic circuit in the base portion 33. A prize winning detector 30a is electrically constructed so that a detection circuit 74 is connected to an oscillation circuit 73 to which an inductance comprising a coil 38, an amplitude modulation circuit 76 is connected to a waveform shaping circuit 75 connected to the detection circuit 74, and further an oscillator 77 is connected to the waveform shaping circuit. Prize winning pinball detectors 30b, 30c are similarly constructed. The respective lead wires of the prize winning pinball detectors 30a, 30b, 30c are respectively connected parallel by wiring of a printed wiring board 50 and connected to a connector 56, the terminal of which is connected to relay terminal 90 by a single signal line 96.
