Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a display board fixing device used for lighting electronic equipment.

Conventional technology FIGS. 4 and 5 show the structure of a conventional display board.

In these figures, 1 is a case of an electronic device, and 2 is a display board, which is usually made of transparent acrylic resin or the like.

3 is a printed circuit board, 4 is a light source lamp attached to a part of the printed circuit board 3, 5 is a switch, and 6 is a button for operating the switch 5, which penetrates the hole 2a of the display board 2 and projects to the front. The user operates it from the front. 7
is attached to the printed circuit board 3 with a volume, and a knob 7b is fitted into the tip of the shaft 7a. Surface 7C of knob 7b or vicinity 7 of knob 7b of case 1
Letters and symbols are often printed on d. A recess 2b is provided at one end of the display board 2, and a hole 2C through which a shaft 7a passes is provided at the other end, and furthermore, on the back side, required characters and symbols 2e are printed on a solid printing section 2d corresponding to each button 6. ing.

Next, the operation of the above conventional example will be explained. Case l display board 2
Adhesive parts 1a and Ib are provided at locations corresponding to the ends of the display board 2, and the display board 2 is adhesively fixed to the case 1. Using the light as a guide, press button 6 or volume 7.
button 6 and the solid printing section 2d.
The characters/symbols 7e, etc. are illuminated, and the vicinity of the knob 7b of the polyurethane 7 is also illuminated by the hole 2C.

Problems to be Solved by the Invention However, according to the above-mentioned conventional display board, when it is fixed, it must be fixed by a method such as gluing, which makes the assembly work troublesome and also causes damage to the inner surface of the case. The disadvantage is that space is required for installation.

SUMMARY OF THE INVENTION An object of the present invention is to provide a display plate fixing device that can solve the problems of the conventional example, can be made thinner, and can be attached with one touch.

Means for Solving the Problems In order to achieve the above object, the present invention provides a shallow recess in the front surface of the case, inserts a display board through a hole at one end of the recess, and supports the display board with the position of the hole as a fulcrum. The display board is rotated and the display board is fixed by engaging means provided between the display board and the side wall of the recess.

Function: Since the present invention is configured as described above, the display board can be attached with one touch, and the display board does not have to be inserted in its entirety into the case, so it has the effect of making effective use of space.

Example An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, 11 is a case made of plastic material, 12 is a display plate made of a transparent material such as acrylic resin, 13 is a boss provided inside the main picture of case 11, and 14
1 is a screw for fixing the printed circuit board 3 to the boss 13;
Reference numeral 5 is a recess formed on the operating surface of the case 11 and has a depth close to the display board 12, 16 is a black plastic sheet, and 17 is an engagement protrusion provided around the display board. The piece 18 corresponds to the protruding piece 17, a small hole provided in the side wall of the recess 15 of the case 11, 19 an air layer, 12a a through hole of the button 6, 12b a groove with a triangular cross section, and 12C a shaft. 7a is a penetrating circular hole, 15a is an engagement hole provided at one end of the recess 15, and 12a is a display plate 12 corresponding to the hole 15a.
The constricted stepped portion 12e is a fixed end. The same reference numerals as in other FIG. 4 represent the same names.

Next, the operation will be explained. First, a method for fixing the display board 12 will be described. As shown in FIG.
Insert the fixed end 12e into the hole 15a of 1).
The display plate 12 is rotated (in the direction of the arrow) so as to press the stepped portion 15a against the fulcrum (b), and the protruding piece 17 serving as an engaging means is engaged with the small hole 18 (c). At this time, the side wall of the recess 15 is slightly bent and opened outward due to the elasticity of the plastic.
Furthermore, the projecting piece 19 is engaged with the small hole 2o. At this time, the elasticity of the display plate 12 is used to facilitate engagement and provide a click sensation.

Next, regarding illumination of the display board, the light emitted from the light source 4 transmits light using the display board 12 as a light guide, and the characters and symbols printed on the back side of the display board 12 are placed on the front surface of the recess 15 with the sheet 16 as a background. 12e is oozed out to illuminate the button 6 from inside, and is emitted into the space from the hole 2c, illuminating the area around the knob 7b.

Note that the protruding piece 17 may be provided on the concave portion 15 side and the small hole 18 may be provided on the display board 12, but in this case, the small hole 18 is visible because it is wedged into the end of the display board 12 and becomes a hindrance. , the configuration described in the above embodiment is more practical.

Effects of the Invention As described above with reference to the embodiments, according to the present invention, a shallow recess is provided in the operating surface of the front of the case, a display board is inserted using the hole at one end of the recess as a guide, and the display board and the side wall of the recess are inserted. The display board is fitted into the case by the engagement means provided between the display board and the display board is configured to transmit light from the light source inside the case using the display board as a light guide. This has the advantage of simplifying the assembly process and reducing the space required for the display board.
