Claims

[Scope of utility model registration request]

A casing, a main circuit section disposed inside the casing, which includes a light emitting element that emits light to be irradiated onto an object surface, and a light receiving element that receives reflected light on the object surface of the light emitted from the light emitting element, and the light emitting element. a projection optical fiber that guides the emitted light to the object surface;
In a fiber-optic photoelectric switch equipped with a light-receiving optical fiber that guides the reflected light from the object surface to a light-receiving element, the casing is equipped with an optical fiber for introducing the optical fiber, corresponding to the ends of both optical fibers on the light-emitting element and light-receiving element sides. A pair of insertion holes are drilled, and a ring-shaped holding spring is provided between the insertion holes so as to protrude into the insertion holes, and the holding spring is attached to the light emitting element along the longitudinal direction of the insertion hole. an auxiliary spring that biases toward the light-receiving element side; and a release shaft interposed between the holding spring and the auxiliary spring; one end of the release shaft passes through the casing, and the insertion hole A fiber optic photoelectric switch with a long hole formed along its length.
