FIG. 1 is a cross-sectional view for explaining a configuration of a specific example of a panel operation plate according to the present invention. In the drawing, an operation plate frame 2 and an opening 3 provided on a front surface of the operation plate frame 2 are shown. Switch part 4 inserted in
The panel operation plate 1 includes a light guide 6 for illuminating the switch unit 4 from the inside, and a substrate 7 on which predetermined components including a light source for supplying light to the light guide 6 are mounted. Thus, the substrate support portion 12 is provided on the surface of the light guide 6 opposite to the surface facing the switch portion 4, and at the same time, the substrate support portion 12 and a part of the operation plate frame 2 are provided. The panel operation plate 1 in which the board 7 is fitted and held between the board operating section 11 and the board fixing section 11 is shown.
