PURPOSE:To eliminate a need for partition of the surface of a bottom side as a transmission and reflection member by sending light from a transmitter means of a master node to a receiver means and reflecting the light on a reflecting face between selected nodes for the communication. CONSTITUTION:An object node 40 is selected by a pixel electronic device relating to each transmitter node 42. A switched signal is sent from the transmitter 42 toward a plane reflector 20 upward in the vertical direction, and a signal is reflected on the plane reflector toward an object receiver decided in advance in the object node 40. Since the light is guided from the transmitter 42 to the object optical receiver by one hopping, a collimation/deflection plane optical member 46 requires an interface 44. Thus, a space between a node division plane 18 and a reflector 20 is shared by layers 52, 54 made of an optically transparent material. The transmission distance is a distance (length of layer 54) between a node division plane 8 and a transparent optical member array in the interface 44. |
