PURPOSE:To attain high speed communication among modules by forming an optical bus through which an optical signal is propagated to a free space among the plural modules realizing a prescribed function and coupling the plural modules via the optical bus. CONSTITUTION:An optical signal sent from an electronic module 110 is received by a photoelectric circuit 124 of an electronic module 120 on an optical axis at the right side of the electronic module 110 and converted into an electric signal. Then the signal is branched into two circuits, an interface circuit 123 and the circuit 124 and the signal received by the circuit 123 is sent to a processor 121 or a memory 122. Moreover, the signal sent to an electric optic conversion circuit is converted again into an optical signal and sent to an electronic module 130. The transmission reception procedure from the electronic module 130 to an electronic module 150 after that is the same repetition as the procedure by the electronic module 120. Thus, the broadcast type transmission aiming at all the electronic modules is executed. |
