Abstract:
1. A remote control transmitter, comprising: an input device that receives an input operation; a controller in communication with the input device to output a control signal in response to the input operation; a light emitting device, which is housed in a front end part of a case and is in communication with the controller, that emits and outputs an optical control signal toward the front of the case in response to the control signal; and a transparent protective filter, which is attached to the transmitter on a front surface of the case, that covers the front of the light emitting device; wherein: the transparent protective filter is formed as a strip shaped, long and thin plate that comprises a transparent material having a refractive index that is larger than the refractive index of air, and is attached to the transmitter so that it is oriented frontwards from the front surface of the case, such that a rear end surface of the transparent protective filter in a longitudinal direction of the transmitter opposes the light emitting device; the optical control signal is emitted and output from a front end surface of the transparent protective filter, which is attached to the case; and a liquid crystal display panel attached to and along a back surface side of the transparent protective filter, the panel being attached to the case so that a face surface of the plate is supported horizontally by the panel, wherein: the input device comprises a transparent touch panel input apparatus, having two transparent electrodes that are disposed on opposing surfaces of two transparent touch panel sheets, which are stacked on and along the face surface of the transparent protective filter so that they are spaced apart by a small gap.
