１記載の光電センサ付き器具。[Scope of Claim for Utility Model Registration] (1) A plurality of light emitting/receiving sections each consisting of a pair of light emitting/receiving elements, a detection section that detects the presence or absence of an object from the received light output of the light emitting/receiving sections, and a time-sharing system for each of the light emitting/receiving sections. A device equipped with a photoelectric sensor, comprising: a control section that operates intermittently cyclically during the light emitting/receiving period of each light projecting/receiving section, and inputs the light reception output of each light projecting/receiving section to a detection section during the light emitting/receiving period of each light projecting/receiving section. (2) When multiple internal mechanisms of the instrument body that operate when an object is detected from the light output of each of the light emitting and receiving sections mentioned above perform a series of operations, the light emitting and receiving section that corresponds to the internal mechanism that operates first 2. The device with a photoelectric sensor according to claim 1, wherein after an object is detected from the output of the received light, a light emitting/receiving section corresponding to an internal mechanism that will be operated later is operated.
