Inventor: UGAWA SHOHACHI
IPC: A63F7/02
Filed: 1997-12-09
Abstract: PROBLEM TO BE SOLVED: To provide a pachinko game machine in which an illegal circuit board cannot be connected between a starting winning ball detection means and a game control circuit board and the game control circuit board is not adversely affected. SOLUTION: A connection between a starting winning ball detector 93 and a game control circuit board 87 is provided inside a circuit board box 80, and the part of a ball passage 120 from a starting winning hole 43 to the game control circuit board 87 is made from a conductive synthetic resin receiving static electricity from shot balls that entered the starting winning hole 43. Therefore, because the connection between the starting winning ball detector 93 and the game control circuit board 87 is located inside the circuit board box 80, an illegal circuit board is difficult to be interposed between them.  Also, even if the shot balls that entered the starting winning hole 43 are charged with static electricity, the static electricity is released to the outside from the ball passage 120 serving as a conductive member, so that even if the shot balls are guided into the circuit board box 80, they do not adversely affect the game control circuit board 87.
