Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention relates to a front panel display device for audio equipment, particularly a car stereo. In detail, the present invention is a car stereo in which the pushbutton that protrudes from the front panel is surrounded by a rib of a transparent display board, and by illuminating the rib with light, it creates an aesthetic effect and improves operability in the dark. The present invention relates to a display device that improves performance.

(B) Prior art A plurality of through holes are formed in the front panel of a car stereo to allow a plurality of push buttons to protrude, but generally nothing is done around the through holes, and the front panel of a car stereo is When using the stereo at night, the push button was difficult to operate in the dark.

For this reason, some push buttons are made of a translucent material and are configured to irradiate light onto the push buttons. However, providing a lighting lamp for each push button is difficult because the front panel of a car stereo requires a small space. Therefore, it was difficult to design and at the same time expensive.

Furthermore, when the push buttons have different sizes, the lighting structure becomes more complicated.

(c) Purpose of the invention This invention uses a single illumination lamp to uniformly illuminate the surroundings of multiple through holes protruding from multiple push buttons of different sizes, making it easy to locate the push buttons even in the dark. It is designed so that it can be recognized.

(d) Structure of the invention The invention consists of a front panel made of black synthetic resin having a plurality of adjacent through holes of different sizes and a plurality of mounting legs formed on the back side;
(b) A plurality of button insertion holes having a similar shape to each of the through holes of the front panel, a protruding rib formed around each of the button insertion holes and fitting into the inner periphery of each of the through holes, and a single light emitting element. It consists of a transparent display plate having a through hole for inserting the element and a V-cut surface formed on the outer circumferential side surface to irradiate the light from the light emitting element to each rib, and ○C a plurality of the transparent display plates on the back surface of the front panel. When the ribs of the transparent display board are positioned and fitted into the through holes of the front panel, a single light emitting element is attached to each rib exposed from each of the through holes of the front panel. The present invention provides a front panel display device characterized in that it is configured to emit light.

(e) Embodiments of the invention Examples of the apparatus of the invention shown in the drawings will be described below.

As shown in FIG. 1, a car stereo 1, which is generally referred to as an induction type, has adjustment shafts 2 and 3 such as a volume that protrude from the left and right at a predetermined distance. A front panel 4 is provided. The front panel 4 is provided with a window 5 for inserting a cassette (not shown) and a plurality of through holes for protruding various push buttons 6.

The embodiment of the present invention, as shown in the perspective view in FIG. It is meant to be done. In this case, the sizes of the through holes 7a and 7b are the same, but the through hole 7c has a larger shape than the others.

In FIG. 2, reference numerals 8, 8, 8, 8 indicate mounting legs integrally formed on the back surface of the front panel 4, and the front panel 4 is molded from black synthetic resin. Reference numeral 9 indicates a plurality of button insertion holes 10a, 10b, 10c having similar shapes to the respective through holes 7a, 7b, 7c.
The transparent display board 9 has mounting legs 8,
8, 8, 8, the four corners are fitted and attached.

Further, on the surface of the transparent display plate 9, protruding ribs 11a, 11b, 11c that fit into the inner circumferences of the through holes 7a, 7b, 7c on the front panel 4 side form button insertion holes 10a, 10b, 10c, respectively. Furthermore, a through hole 13 into which a single illumination lamp 12 is inserted is formed in the center of the transparent display plate 9.

Furthermore, V-cut surfaces 14a, 14b, and 14c are formed on the outer circumferential side of the transparent display plate 9, and the illumination lamp 12 inserted into the through hole 13 is provided with V-cut surfaces 14a, 14c, as shown in FIG. 14b, 14c
The structure is such that the lamp light is evenly distributed around the area as shown by the arrows.

Since the present invention is configured as described above,
When the transparent display board 9 is attached to the back surface of the front panel 4 in close contact with the mounting legs 8, 8, 8, 8, ribs 11a, 11b formed surrounding the button insertion holes 10a, 10b, 10c of the transparent display board 9 , 11c,
By positioning and fitting the single illuminating lamp 12 into the through holes 7a, 7b, and 7c of the front panel 4, and inserting the single illuminating lamp 12 into the central through hole of the transparent display plate 9, the light of this illuminating lamp 12 is V cut side 14
a, 14b, and 14c, which can be evenly distributed around the surrounding area.

Therefore, the light from the single illumination lamp 12 can be irradiated onto the ribs 11a, 11b, 11c exposed from around the through holes 7a, 7b, 7c of the front panel 4, so that As shown, the surroundings of the push buttons 15a, 15b, and 15c can be displayed optically.

Note that the ribs 11a, 11b, 11c that are irradiated with light by the illumination lamp 12 are located on the front panel 4.
Since it is made of black synthetic resin, it emits bright light with almost no light leakage.

(c) Effects of the invention According to the invention configured as described above, the installation work is extremely simple because the transparent display plate is simply fitted and installed into the plurality of through holes in the front panel. In addition, this transparent display board has a cut surface that allows the light from a single illumination lamp to be evenly dispersed around the surrounding area, and the light also shines through the exposed ribs that fit around the inner periphery of each through hole. Because it can illuminate the area around the pushbuttons, it is possible to optically display the area surrounding the pushbuttons, and there is no need to place dedicated lighting lamps for each pushbutton, so it can be used in a small car stereo space. This is a practical display device that effectively displays the front panel of a computer.

According to the device of the present invention, when attaching the transparent display plate to the front panel, the ribs of the transparent display plate can be used for positioning the through holes of different sizes in the front panel, so that there is no possibility of mistakes. It is possible to avoid mounting in the wrong direction.

Furthermore, since the ribs are formed in a protruding shape, they have the effect of condensing the irradiated light into a linear shape, and together with the front panel made of black synthetic resin, the ribs produce a state of vivid light emission.
