PURPOSE:To attain various controlling operations by providing a light emission section having a rotary mechanism and a lighting window through which a light radiating from the light emission section passes to the remote controller so as to allow the light emission section to radiate its light almost in the horizontal direction by means of its self-weight and the rotary mechanism. CONSTITUTION:A light emitting section 4 is soldered to a printed circuit board 7 provided with a rotary mechanism 6 and interconnected electrically with a printed circuit board 5 by a wire 8. Moreover, a light emitting window 3 is provided with an opening larger than that of a conventional controller and leading up to a lower face outer package 2. When the wireless remote controller is set upright, the light emitting section 4 and the printed circuit board 7 are turned around the rotary mechanism 6 by their self-weight and the light emitting section 4 is directed in the horizontal direction without fail. That is, when an electronic equipment 9 is operated while the wireless remote controller 12 is stood upright, the light passes along a locus 11 through the light emitting window 3 and reaches a light receiving window 10. Even when the wireless remote controller 12 is stood in any attitude at an optional angle between the horizontal and vertical directions, the light emitting section 4 and the printed circuit board 7 are turned around the rotary mechanism 6 by their self-weight, and the light emitting section 4 is directed in the same horizontal direction without fail and the light reaches the light receiving window 10 of the electronic device 9. |
