1. A signal transmission apparatus for a steering control board comprising:

  • a steering control board disposed near a steering wheel in a floating relation with respect to said steering wheel and equipped with switches;

    stationary member for supporting said steering wheel;

    at least two light emitting means disposed on at least either one of said steering control board and said stationary member at different positions located outside of the position where at least one spoke for supporting said steering wheel is supported, so that all of said light emitting means are not entered in the projected area of said spoke at the same time;

    at least two light receiving means disposed on at least the other one of said steering control board and said stationary member at positions opposite to said light emitting means, respectively, whereby at least one light path between one of the light emitting means and the opposed light receiving means is maintained at all times during rotation of the steering wheel;

    a light emission energizing means adapted to energize said light emitting means;

    a modulating means connected to said light emission energizing means;

    a first control means adapted to control said modulating means;
