According to the above configuration, since the power switch is incorporated in the receiver exposed to the outside, the power switch can be easily turned on and off without opening the front panel as in the conventional case. Can be. In addition, since the power switch is incorporated in the receiver and the housing does not need to be processed, the manufacturing cost can be reduced.

According to a second aspect of the present invention, in the first aspect of the present invention, the decorative plate is movably fitted into the opening, and a spring is provided for urging the decorative plate outward. A power switch is arranged between the decorative board and the printed circuit board.

According to the above configuration, the power switch can be turned on / off simply by pushing the decorative plate against the spring. In addition, since the power switch is hidden behind the decorative plate, the appearance can be favorably maintained.

According to a third aspect of the present invention, in the second aspect, the spring is built in the power switch.

According to the above configuration, the decorative board is urged outward by using the spring built in the power switch, and the manufacturing cost is lower than when the spring is provided separately from the power switch. Can be cheaper.

According to a fourth aspect of the present invention, in the invention according to any one of the first to third aspects, a light emitting device which is lit when the power switch is turned on is attached to the printed circuit board, and the decorative plate is provided. A lighting display window is provided at a position facing the light emitting device.

According to the above configuration, the ON state of the power switch can be easily confirmed by turning on the light emitter.

According to a fifth aspect of the present invention, in any one of the first to fourth aspects of the present invention, the electronic device is an indoor unit of an air conditioner.

According to the above configuration, it is possible to provide a remote control operation type indoor unit of an air conditioner excellent in energy saving measures.
