するフオトセンサ。[Claims for Utility Model Registration] The presence of an object, etc. in the detection area is detected by irradiating pulse modulated light from a light emitting element onto a detection area and detecting the reflected light from the detection area with a light receiving element. In this photo sensor, the normal detection function and the barcode reading function can be controlled by switching the mode, and when the barcode reading function is selected, the predetermined information in the barcode table is When the barcode is scanned while facing the light emitting element and the light receiving element, various control settings such as sensitivity and hysteresis characteristics corresponding to the predetermined barcode are performed based on the detected light of the light receiving element. A photo sensor characterized by:
