Inventor: KOBAYASHI SHUICHI
IPC: A63F7/02
Filed: 2000-03-29
Abstract: PROBLEM TO BE SOLVED: To eliminate the evil effect that even noise signals mixed in a signal transmission line to a main controller are expanded and they are erroneously judged as winning ball detection signals in the main controller in a pachinko machine for which winning ball detection leakage is eliminated by expanding the pulse width of the signal and turning it to the winning ball detection signal of a check cycle or more even when a winning ball passes through the detection position at a high speed and the winning ball detection signal of a short time less than the check cycle is outputted. SOLUTION: A pulse width expansion circuit 2 for expanding the pulse width of the winning ball detection signal of a short time less than a winning ball check cycle and turning it to the winning ball detection signal of the check cycle or more is provided not on the side of the main controller but on the side of this winning ball detection switch circuit and the noise signals mixed in the signal transmission line to the main controller are prevented from being expanded in the main controller.
