ホトインタラプタ。[Claims for Utility Model Registration] (1) The light emitting part and the light receiving part are juxtaposed with both facing forward, and the light emitted from the light emitting part hits the object to be detected in front and is reflected. In a reflective photointerrupter that detects the presence or absence of an object to be detected by receiving light at a light receiving part, at least a plurality of emitted lights are emitted forward from the light emitting part, and each optical axis of these emitted lights is aligned with the light receiving part. 1. A reflective photointerrupter characterized by intersecting the optical axis of incident light at a plurality of different points. (2) The light emitting section includes one light emitting element and a plurality of light emitting elements that reflect forward the emitted light that is emitted from the light emitting element and spreads away from the optical axis of the emitted light emitted forward. 2. A reflective photointerrupter according to claim 1, which is comprised of a plurality of reflective plates. (3) The reflective photointerrupter according to claim 1, wherein the light emitting section is composed of a plurality of light emitting elements.
