Abstract
A mobile telephone holding device is provided for establishing a stable communication between a portable telephone and outside on-board instruments without adjusting the positions of respective infrared optical communication interfaces precisely. The holding device includes a light guide disposed between a plane containing one surface of the portable telephone equipped with an infrared optical communication interface and one end face opposing a housing equipped with an IrDA element . The light guide operates to direct an optical path of a light signal entering through one surface of the guide to a direction of the other surface. The transmission and receiving of optical signals is accomplished between the telephone and the instruments through the light guide
