BALL EXHAUSTION DETECTOR FOR JAPANESE PIN BALL GAME MACHINE

摘要

PURPOSE: To prevent the malfunction or detection error of a ball exhaustion detecting mechanism by detecting the exhaustion of balls over two stages. ;CONSTITUTION: At a ball replenishing part 25, first and second ball exhaustion operating pieces 20 and 21 are adjacently installed to be respectively oscillated when the number of received pin balls is decreased less than a limit, the first ball exhaustion operating piece 20 is linked to a ball exhaustion detecting switch 28, and the second ball exhaustion operating piece 21 is linked to a transmitting mechanism. When the balls are exhausted at the ball replenishing part 25, first of all, the first ball exhaustion operating piece 20 is operated and the ball exhaustion detecting switch 28 outputs a ball exhaust signal. Continuously, the second ball exhaustion operating piece 21 is operated and corresponding to its action, the transmitting mechanism is operated for dealing with the exhaustion of balls.;COPYRIGHT: (C)1995,JPO
