FIG. 2 is a perspective view showing the lamp case of the present invention shown in the embodiment of FIG. 1 together with a transparent cover.

That is, the lamp case 10 of the present invention has indicator light opening windows 13 in which display elements such as LEDs are placed on the printed circuit board at two places on the upper part of the transparent cover mounting surface 11.
At the same time, a panel mounting portion 14 is provided with locking pieces 15 cut and raised from four locations on the top, bottom, left and right of the case body, and extends toward the back surface. Furthermore, a stud mounting portion 16 that is open to the front is integrally formed at the lower center of the transparent cover mounting surface 12.

The transparent cover 11 is fitted and fixed to the transparent cover mounting surface 12 of the lamp case 10 with a name plate 19 made of paper or the like in between. The open stud mounting portion 16 becomes invisible from the outside.

Next, the mounting structure of the printed circuit board using the lamp case of the present invention shown in Figs. 1 and 2 will be explained.
First, as shown in FIG.
When pushed in, the lamp case 10 can be supported and fixed to the panel window 2 of the panel board 1 by engaging the locking piece 15 formed by cutting and raising the panel mounting part 14. Next, a commercially available stud member 18 made of synthetic resin is press-fitted into the stud insertion hole 17 of the stud mounting part 16 provided integrally with the lamp case 10 and supported and fixed, and the stud member 18 is attached to the lamp case 10. The printed circuit board 6 on which a display element 7 such as an LED is provided is supported and fixed to the lamp case 10 by fitting it into a stud member 18 supported by the lamp case 10.

According to the support and fixation of the printed circuit board 6 using the stud member 18 supported and fixed to the stud mounting portion 16 of the lamp case 10, the printed circuit board 6 can be simply mounted without requiring screw-in work. Since it is only necessary to push the hole into the stud member 18, it is possible to attach the printed circuit board 6 to the back surface of the panel 1 very easily. 7 can also be easily aligned.

FIG. 3 is a sectional view of another printed circuit board mounting structure using the lamp case of the present invention, and in this embodiment, a stud member 18 of large size is used for mounting the printed circuit board 6.
