摘要： A lens frame, made from metal, retaining a light-emitting lens and a light-receiving lens is retained between a second mold and a third mold both of which are made from light-shielding resins. Anchors are formed by filling light-shielding resin for forming the third mold into fixing slots formed in an upper surface of the second mold and through holes formed in the lens frame. Since the lens frame is made from metal, thermal expansion of the lens frame is hardly caused by ambient temperature changes and self-heating. This causes little difference in the amount of change in difference between the lenses. Further, the lens frame is fixed with anchors between the second mold and the third mold. This suppresses the occurrence of sliding caused by difference in thermal expansion coefficient between the lens frame and the second and third molds.

摘要： An optical distance measuring sensor has a plurality of light-emitting elements, a light-emitting lens, a photodetector having a light-receiving surface, a light emission driving part to sequentially drive the light-emitting elements, and a distance signal outputting part. Light emitted from each light-emitting element passes through the light-emitting lens, then is reflected by an object to be detected, and then gets incident on the light-receiving surface of the photodetector, which outputs a signal corresponding to a position of the incident light in the light-receiving surface. Upon receipt of the signal, the distance signal outputting part outputs a distance signal representing a distance to the object.
