The transmitted signal is converted into an optical signal by an electric-to-optical converter 15, and is transmitted to the optical-to-electrical converter 16 of the receiving side circuit board unit 12, as shown by the dotted arrow in the figure. However, the light-
The light is received by the electrical converter 16, converted into an electrical signal, and input to the receiving side circuit board unit 12. In such a configuration, the circuit board units 11 and 12 on the transmitting side and the receiving side
Since the space between them is electrically insulated, there is no possibility of them having a negative effect on each other. In addition, the electric-to-optical converter 15 and the optical-to-electrical converter 16 are arranged facing each other using the notches 13 and 14, and light is directly transmitted through the space, so it is not possible to use an optical connector or an optical fiber as in the conventional case. There is no need to use any of the above, which improves economic efficiency and is easy to handle. still converter 15
