Abstract

Abstract PURPOSE:To facilitate mutual connections between a host computer and many terminal equipments, by utilizing a space propagation path, and converting a spot signal into a plane signal by a light signal, and performing signal transmission and reception to and from other systems. CONSTITUTION:The light reflecting plate 8 of an optical communication device 10 uses a convex mirror to function to disperse a light signal from an optical transmitter and receiver 6 in many directions and also to converge light signals incident in many directions to a photodetection surface. Therefore, signals outputted from a computer and a terminal equipment 1 are converted into light signals, which are radiated in many directions. Light signals incident in many directions, on the other hand, are converted into electric signals, which are inputted to the computer and terminal equipment 1.
