Abstract
Microphones and key switches are provided on an operation board mounted on a steering wheel, and an audio signal as well as a control signal generated therefrom are sent to a road-vehicle stationary unit through a light transmission means including plural pairs of light emitting and receiving elements, thereby to supply the audio signal to be transmitted and to make sending/receiving control for a radio communication apparatus incorporated in the road-vehicle stationary unit. The operation board is mounted in a floating relation with respect to the steering wheel and an optical path of the light transmission means is formed in plural number, so that all these optical paths are not interrupted by spokes for supporting the steering wheel simultaneously at the least.
