Title: Photoelectric detector
Inventor: IMAZU KEINOSUKE
IPC: G01B11/02
Filed: 1987-01-29
Abstract: PURPOSE:To eliminate mutual interference of optical sensors of a device having plural photoelectric sensors by latching the photodetection signal of one line respectively at the prescribed timings during the driving period of corresponding light emitting elements. CONSTITUTION:The light emitting elements 10a-17a of the plural photoelectric sensors 10-17 are sequentially driven in specified order. Light is emitted from the single light emitting element at each moment thereof. The photodetection signals of light receiving elements 10b-17b are sent by one line 41 to plural latching circuits 20-27. The latching operation of the corresponding latching circuits 20-27 is executed in the driving period of the respective elements 10a-17a. The signal received in the corresponding circuits 20-27 are, therefore, regarded to be the photodetection signals of the elements 10b-17b making a pair with the elements 10a-17a which are driven to emit light even if the photodetection signals of the elements 10b-17b are transmitted by one line 41. The plural photoelectric sensors 10-17 operate time dividedly in such a manner and the mutual interference of the sensors 10-17 is prevented.
