PURPOSE:To improve the precision of optical communication by keeping invariably normal in the relative position relation between a transmitter and a receiver sides. CONSTITUTION:The incidence direction of a light signal sent by the transmitter side is detected by a photosensor 22 and the axes of rotation of lenses 20 are controlled by the detection signal so that the lenses face invariably in the incidence direction of the light signal. A photoelectric converting element 21 is arranged at the focal point of every lens 20 and the light signal received by the photoelectric converting element 21 is converted into an electric signal for regeneration. Therefore, the transmitter and receiver are kept invariably normal in the relative position relation. |
