Abstract

PURPOSE:To perform switching without any loss even if the number of terminals increases and prevent an increase in price by selecting a photodetecting element by a gate circuit and receiving an optional light signal selectively among light signals from light emitting elements. CONSTITUTION:Light emitted by light emitting elements 1-1-1-16 is converged through a lens 2-1a and photodetected by a corresponding photodetection part 2-1b. Similarly, a photodetection part 2-2b, etc., photodetect light. Light shield plates 3 and 4 are provided. Further, photodetecting elements x1-x16 are arrayed on the surface of the photodetection part 2-1b, and light from the light emitting element 1-1 is incident on the photodetecting element x1 of the photodetection part 2-1b. An optional output among outputs of the photodetect ing elements x1-x16 is selected by a gate circuit 2-1c. Namely, an optional light emitting element is selected.
