るように寸法等を設定しておく。 Hereinafter, one embodiment of the present invention will be described in detail with reference to FIG. In the figure, 9 is a panel made of synthetic resin, and 10 is a display hole provided in a part of the panel. The guide portion 12 has a small diameter and a tapered shape that widens toward the back side. A display light guide 13 made of a colored and transparent synthetic resin is fitted and attached to the large diameter portion 11, and a decorative plate 14 such as a thin aluminum plate is attached to the entire surface of the panel 9 to guide the light. Only the display protrusion 15 at the center of the body 13 is made to protrude forward. On the other hand, 16 is a printed circuit board to which an elastic body 17 such as a sponge is adhered, and a light emitting element 18 such as a light emitting diode is attached thereon by bonding or the like. The electrode 19 of the light emitting element 18 is connected to the printed circuit board 16. Then, the light emitting part 20 of the light emitting element 18 attached in this way is inserted into the through hole 1 of the panel 9.
The printed circuit board 16 is attached to the back surface of the panel 9 with screws 21 while being fitted into the guide portion 12 of the panel 9. At this time, the screw hole 22 for mounting the printed circuit board is made into an elongated shape so that the printed circuit board 16 can be moved up and down a little during mounting, and the elastic body 17 is used to hold the light emitting element 1.
The dimensions and the like are set so that the light emitting section 20 of No. 8 is elastically pressed against the guide section 12.

い。 With the above configuration, when the printed circuit board 16 is attached to the panel 9, the light emitting part 20 of the light emitting element 18 is connected to the guide part 1 of the through hole 10 by the elastic body 17.
2 and make a through hole 10 along its tapered slope.
, that is, the center position of the light guide 13 . At this time, by slightly moving the printed circuit board 16 up and down through the screw holes 22, the light emitting section 20 can be inserted smoothly. Further, it is even better if a recess 23 is provided at the center of the back surface of the light guide 13 so that the tip of the light emitting part 20 is fitted therein.

る。 In this way, the light emitting section 20 is connected to the light guide 1.
Since the panel 9 can be correctly attached in a state aligned with the center position of the panel 3, the display on the front side of the panel 9 can always be displayed with even brightness and with sufficient brightness. Further, by using the guide portion 12 and the elastic body 17 in this way, it is possible to make the work for correctly installing the product extremely easy, and the work efficiency can be significantly improved. Since it can always be installed correctly even by an untrained worker, the quality of the finished product can be made uniform and reliability can be improved.
