とした光反射式センサ装置。[Claims for Utility Model Registration] Comprising a first light-emitting element and a light-receiving element, the light-receiving element extracts reflected light from an obstacle received by the light-receiving element via a signal detection circuit, and outputs a detection information output circuit that detects a signal above a certain level. In a light reflection type sensor device configured to output reflected light, a predetermined light is sent to the first light emitting element and the light receiving element in a direction rotated by 90 degrees from the light emitting element and the light receiving element, and the light is reflected. A light reflection type sensor comprising: a second light-emitting element and a light-receiving element that receive light; and an addition circuit between each of the first and second light-receiving elements and the detection information output circuit. Device.
