PURPOSE:To decrease the distance between adjacent elements and to eliminate the need for a shield film by arranging a lens collecting an emitted light of a prescribed light emitting element of a light emitting element array to a prescribed photodetecting element of a photodetector array between the light emitting element array and the photodetecting element array, allowing the photodetecting element to receive the emitted light of the light emitting element so as to apply parallel communication of information. CONSTITUTION:In response to a data given from sender side signal lines D0-D7, STB,LED drivers 6a-6i drive light emitting diodes 2a-2i, and an emitted light of the light emitting diode is collected to a photodiode in the optical coupling relation of photo diodes 4a-4i and the emitted light emitting diode in the light emitting diodes 2a4n2i by a lens 5. Photoelectric conversion is applied by the collected photodiode, the output of the photodiodes 4a-4i is amplified by amplifiers 7a-7i and outputted to reception side signal lines STB',D7'-D0' and data communication is attained between the the sender signal lines D0-D7, STB and the reception side signal lines D0'-D7',STB'. |
