ABSTRACT:
There is disclosed an electronic apparatus in which signal transmission, for example a command signal from a control unit or a detection signal from a detector, is conducted by light from an emitting unit to a receiving unit. This eliminates signal transmission by cables, thus avoiding complicated wiring operations, preventing noises and reducing the volume of the apparatus.
