Title: Multiple optical axes photoelectric switch
Inventor: TANAKA KUNIO
IPC: H03K17/78
Filed: 1994-03-24
Abstract: PURPOSE:To detect a state that the light from a light projecting element is shielded with high accuracy by providing plural amplifier means individually amplifying the output of each of plural light receiving elements and plural selection means selecting this output. CONSTITUTION:Light is successively projected from plural light projecting elements 7a to 7c and light is individually projected to plural light receiving elements 8a to 8c. The output of each of the light receiving elements 8a to 8c is amplified by amplifier means 9a to 9c and each output is selected by a selection means in accordance with a light projecting order. By the selected output of the amplifier means, the light shielding state between the light projecting elements 7a to 7c and the light receiving elements 8a to 8c is detected. When the amplifier means 9a to 9c are made to perform an amplifying operation, the selection means selects the output amplified by the amplifier means 9a to 9c by interlocking with the operation. When the amplifier means 9a to 9c are not made to perform the amplifier operation, the selection means does not select the outputs of the amplifier means 9a to 9c by interlocking with the operation. Thus, the selection means is capable of selecting only the outputs of the light receiving element receiving the light from the light projecting element.
