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. The lens frame has an asperity structure on its front and back surfaces. This greatly enhances adhesiveness between the light-emitting lens and the lens frame and adhesiveness between the light-receiving lens and the lens frame, thus preventing sliding of the light-emitting lens and the light-receiving lens over the lens frame.

摘要： In this multi-beam optical range sensor, since the diffraction grating splits output light of the light-emitting element into a plurality of beams, a plurality of beams can be outputted from the diffraction grating even with one light-emitting element. Therefore, according to this multi-beam optical range sensor, the numbers of the light-emitting elements and the light-emission side lenses can be cut down, the space on the light emission side can be reduced, and the sensor can be downsized. Also according to this range sensor, there is no need for scanning a plurality of light-emitting elements and so the detection time can be shortened.

摘要： An optical object identifying device has a light-emitting device, a first photodetector and a second photodetector. In the optical object identifying device, an angle of 10 to 30 degrees is formed between the optical axis of the light-emitting device and the surface of the sheet to be identified. Also, an angle of 10 to 30 degrees is formed between the optical axis of the first photodetector and the surface of the sheet. Further, an angle of approximately 90 degrees is formed between the optical axis of the second photodetector and the surface of the sheet. Thus, the light-emitting device, the first photodetector and the second photodetector are arranged in the optimum positions, so that the first photodetector and the second photodetector can obtain two output values varied with each of many types of sheets.

摘要： An optical distance measuring sensor has a plurality of light-emitting elements (51-55), a light-emitting lens (1), a photodetector (4) having a light-receiving surface, a light emission driving part (31) to sequentially drive the light-emitting elements, and a distance signal outputting part (31). Light emitted from each light-emitting element passes through the light-emitting lens, then is reflected by an object (32) 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.
