Abstract

PURPOSE:To obtain a high light receiving gain by a method wherein a focusing device receiving the optical signal of a photoconductive ring in a light transmitting path is provided for transmitting optically the signal outputted by the operation of switches provided on a steering wheel for controlling the loads for a vehicle power. CONSTITUTION:When a plurality of steering switches 17a-17k provided on the steering wheel 13 is operated, a corresponding pulse encoding signal is outputted from an encoder circuit 21 and an optical signal, in accordance with the pulse encoding signal, is outputted from a current to light converting circuit 22 comprising a luminous element 22a consisting of a luminous diode, for example. This optical signal is inputted into a receptor element 24 through the photoconductive ring 23, is converted into an electric signal and is amplified by an amplifier 25 subsequently, thereafter, is impressed into a driving circuit 28 through a threshold circuit 26 and a decoder circuit 27 to drive a corresponding switch of the load. In the above-described constitution, the focusing device 30, collecting the optical signal outputted from the light outputting surface 23a of the photoconductive ring 23 and leading it to the receptor element 24, is equipped.
