PROBLEM TO BE SOLVED: To provide an optical bus circuit board high in light availability and distributive uniformity. SOLUTION: Electrical signals from an electronic circuit board 204 are converted into optical signals by an electric/optic conversion circuit 40, optical signals are generated from a laser diode 414, and generated optical signals are entered into the end surface of a translucent medium 51. The entered optical signals undergo repeated total reflections and are propagated within the translucent medium 51, are exited from the other end surface of the light translucent medium 51 and are received by photodiodes 611-618. Received optical signals are converted into electrical signals by an opto-electric conversion circuit 60 and are transmitted to respective electronic circuit boards 201-208. |
