Claims

[Claims for Utility Model Registration] A light emitting element and a light receiving element are arranged with a gap for an optical coupling path, and an object detection signal is output by blocking the optical coupling path with an object. In the interrupter, the light emitting element and the light receiving element are arranged on the same plane at a predetermined interval and facing the same direction perpendicular to the plane, and the light emitting element and the light receiving element are made of a light-transmitting material. The light emitting element is embedded in a light emitting element accommodating part and a light receiving element accommodating part which are molded, and the light emitted from the light emitting element is directed along the optical coupling path to a position facing the light emitting element in the light emitting element accommodating part. a first total reflection slope formed to allow reflection to proceed;
a second total reflection slope formed at a position facing the light receiving element in the light receiving element accommodating portion so as to reflect and advance the light traveling along the optical coupling path toward the light receiving element; An ultra-small interrupter characterized in that a mask means for restricting a light flux surface area of the optical coupling path is provided on opposing side wall surfaces of the optical element accommodating part and the light receiving element accommodating part.
