ABSTRACT:
A game machine encoder with a rotatable rotary contact panel having a top, a bottom, and a rotary shaft, plural contact portions having a comb-shaped contact portion, a common contact portion, and a further contact portion disposed at the bottom of the rotary contact panel, and plural contact brushes biased toward each contact portion of these plural contact portions. The further contact portion has a detection signal portion for detecting the origin position of the rotary contact panel. Each contact portion of the comb-shaped contact portion, common contact portion and further contact portion is disposed on concentric circles having centers corresponding with the center of the rotary shaft. When the encoder rotates, two sets of contact brushes out of the plural contact brushes open and close to provide a first signal and a second signal having waveforms mutually different in phase, and another set of contact brushes opens and closes to provide a detection signal for detecting the origin position. Every time the rotary contact panel returns to the origin position, the count can be corrected.
