PROBLEM TO BE SOLVED: To extend a range of receiving an optical remote control signal by arranging a light collection section whose surface is projected and whose inside is recessed in the vicinity of the remote control light receiving section. SOLUTION: An optical remote control signal 7, e.g. an infrared ray outputted from an optical remote controller 6 is refracted on the projection of the surface of a lens 1 and further refracted at a recessed part 4 in the inside of the lens 1 and collected by a light receiving section 5. Thus, according to this system, a control signal from the remote controller at the out side of a light receiving range is received by the light receiving section 5. The light collection section is mounted easily to the light receiving section 5 by using a mount section 3 that is provided with a circular stripe double-sided tape or a soft sponge-like material clipped by a double-sided tape so that the light collection section is easily mounted to a part with more or less projection and recess. In this case, the optical remote control light receiving section extends its directivity up to a range of around 180 deg.. That is, the receptible range of the remote controller is extended widely by mounting the light collection section to the light receiving section 5. |
