DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a display card fixing structure according to the present invention will be described below with reference to the drawings. The present invention, as shown in FIG. 1, employs a display card fixing structure for fixing a display card 4 on which a name and the like are described to an electronic device housing 3 such as an intercom slave unit, and includes electronic components (not shown).
An electronic device housing 3 is configured by fitting a resin cover 1 in order to exteriorize the inner case 2 that houses the electronic device.

In order to fix the display card 4 to the electronic device housing 3, a window 10 through which the display card 4 is inserted and held is formed in the cover 1. The window 10 has a pair of holding parts 10a and 10a either vertically or horizontally. As shown in FIG. 2B, the width M of the window 10 is set to be equal to the width N of the display card 4 so that the window 10 is smaller than the display card 4.
If it is drilled slightly smaller, a pair of windows 10
The display card 4 is pressed from the front side by a and 10a. More preferably, the holding portion 10a that covers the display card 4 with the back surface 10b of the window is made thin, and the corresponding surface 4a of the display card 4 is also made thin to prevent the movement of the display card 4 in the window 10.

At least one pair of elastic claws 12, 12 extend in the direction of the back surface 10b of the window 10 at a position substantially orthogonal to the pair of holding portions 10a, 10a on the outer periphery 11 of the window 10. FIG. 1 shows two pairs of elastic claws 12, 12. Further, in FIG. 1, the elastic claw portion 12 is provided up and down, and the holding portions 10a substantially perpendicular to the claw portion 12 are provided at right and left.
