Abstract

PURPOSE:To secure the application for the common optical transmission and receiver to many control subjects by providing the light radiation directivity to the optical transmitter and then securing a selective control for the control subject unit. CONSTITUTION:Optical transmitter 1 is constituted so as to deliver the visible light signal featuring the sharp light radiation directivity. And with this transmitter 1, the reception part of optical receiver 2 provided to sockets 4 and 4' is irradiated. The control information sent from transmitter 1 is received at receiver 2 and then decoded by the decoder provided at receiver 2, and thus gate 3 is controlled along with the selective control given to load 5. In case the control is given to other load 5', the light irradiation direction of transmitter 1 is changed toward socket 4'. And load 5' is controlled by gate 3'. In such way, many control subjects can be controlled via common transmitter 1 and receiver 2.
