Abstract

PROBLEM TO BE SOLVED: To reduce the number of infrared-ray(IR) emitting elements, to improve a light emitting effect by a reflector built in an IR emitting part and to prevent the consumption of a battery by using a display LED for displaying the ON/OFF of a power supply switch also as the IR emitting part in common. SOLUTION: The IR emitting part 13 is composed of a reflector tool 11 and an IR emitting element 12 and fixed on a board 14. A reflection part 11a is worked by a reflecting material or a fluorescent material, and in the fixed state of the tool 11 and the element 12 on the board 14, infrared rays are reflected in optional directions like arrows 12b. Infrared rays emitted from an IR emitting point 12c are passed upwards through a through hole 11b as shown by a symble 12a. The inclination angles of respective reflection parts 11a can be optionally set up, i.e., equally or differently. Since the reflector tool 11 is arranged in the IR emitting part 13 to improve a light emission/ diffusion effect, noise or sound interruption is not generated even at the time of customer's various operation and the display LED for the power supply switch and the IR emitting part are used in common, the number of IR emitting elements can be reduced.
