PURPOSE:To attain cost reduction by commonly receiving remote control signals from two light receiving parts with one remote control sensor. CONSTITUTION:A light transmission body 12 provided with a first incident plane 12A for which a remote control signal (a) photodetected by the first light receiving part is made almost vertically incident from a direction A like an arrow and this signal (a) is straightly advanced as it is and emitted, second incident plane 12B to which a remote control signal (b) photodetected by the second light receiving part is made almost vertically incident from a direction B like an arrow, and reflection plane 12C for almost perpendicularly reflecting and emitting the remote control signal (b) made incident from this second incident plane 12B, is arranged between the first and second light receiving parts and a remote control sensor 9. |
