4 to the inverter power supply section 20, the night light bulb 24 is turned on and off. Also, when the lamps 26 and 27 are blinked or dimmed by the output of the control unit 28, the buzzer 31
is driven, and an audio control confirmation signal is generated.

In addition, a receiving hole 3a formed in the hollow part 2 of the instrument main body 1
Since the lamps 26 and 27 are located at the top, the receiver 25 will not receive visible light or infrared rays emitted from the lamps 26 and 27 and will not malfunction.

Furthermore, since the control device 22 is disposed inside the upper surface of the chassis portion 2 of the instrument body 1, it is close to the receiving section 25, which is preferably disposed at the top, and wiring can be facilitated.

In addition, since the lighting device 16 is disposed below the control device 22 on the cover part 3 of the appliance body 1, the control device 22 and the lighting device 16 are stacked vertically. can be made smaller, resulting in a more compact overall design.

Further, the instrument main body 1 can be almost the same as a conventional instrument without a remote control device.

Further, a shield plate 32 is placed on the circuit board 17 of the lighting device 16 with an insulating surface, and the shield plate 32 is interposed between the lighting device 16 and the control device 22.
