出器。 A light emitting part and a light receiving part are provided facing each other, and a groove is formed between them for the object to be detected to pass through, and the light emitted from the light emitting element provided in the light emitting part crosses the groove and enters the light receiving part. In a photoelectric detector, the light is detected by a detected object passing through the groove blocking the light. It is covered with metal spring plates so as not to obstruct passage, and these metal spring plates press both the optical elements against the inner surface of the wall forming the case of the light emitting/receiving part by their respective spring forces. photoelectric detector.
