Patent ID: 7760332

Claim:
An optical range-finding sensor comprising: a light-emitting element that is a vertical cavity surface emitting laser and emits irradiation light; a light-emitting side lens that collects the irradiation light and irradiates the light to a range-finding object; a light-receiving side lens that collects reflected light of the irradiation light reflected by the range-finding object; a position detecting light-receiving element that receives the collected reflected light and detects a position of the range-finding object; a control processing integrated circuit that controls light emission of the light-emitting element and process a detection current of the position detecting light-receiving element; a sensor case that holds the light-emitting side lens and the light-receiving side lens; and a single light transmitting resin sealed package which is fitted to the sensor case and by which the light-emitting element and completely by the light-transmitting resin, the position detecting light-receiving element and the control processing integrated circuit are sealed collectively, wherein said optical range-finding sensor performs triangulation range finding.
