設けられていることを特徴とするエンコーダ。 Light transmitting portions or light reflecting portions are provided on the movable plate at predetermined intervals along its rotational direction or linear movement direction,
A photoelectric sensor is fixedly installed corresponding to the moving path of the light transmitting part or the light reflecting part, and each time the light transmitting part or the light reflecting part faces the photoelectric sensor when the movable plate rotates or moves linearly. In the encoder, the photoelectric sensor is adapted to receive transmitted light or reflected light from the light transmitting section or the light reflecting section to output an electrical signal, and the photoelectric sensor is configured to output an electric signal by receiving transmitted light or reflected light from the light transmitting section or the light reflecting section. Three or more of the light transmitting parts or the light reflecting parts are fixedly installed corresponding to the path, and the light transmitting parts or the light reflecting parts are provided at intervals and sizes such that only one of them always faces each other when corresponding to each of the photoelectric sensors. An encoder featuring:
