As shown in FIG. 2, a light source 12 such as an incandescent bulb is disposed on the back side of the display board 11 to illuminate the display board 11 with transmitted light. A gap 14 is provided between the plate 11 and the outer case 13 in a part or the entire circumference, and the light rays from the light source 12 passing through the gap 14 are reflected on the outer case 13, thereby displaying the display. The purpose is to illuminate the fingers 115 on the front side of the plate 11, and at this point, the outside light is placed so that the direct light from the light source 12 does not directly reach the viewer's field of view and cause dazzling. An eaves 16 is placed on the base 13 with a set number.

Second, by arranging the light source on the back side and installing the gap between the display board and the outer case, this
! Another unavoidable problem is that the 511I display section is large in size as a whole. Thirdly, many of these types of instrument panel displays have a sealed structure, so
As mentioned above, the use of incandescent bulbs and the like as a light source causes an extreme temperature rise, and for this reason, it is necessary to select special materials with excellent heat resistance for the members forming the instrument panel display section. However, there are also problems such as the product being inevitably expensive.

In the method of illuminating the instrument panel display section of an automatic teacup, etc., at least one side of the periphery of the display panel of the instrument panel display section is approximately equal to the display panel. EL (electroluminescence) light-emitting elements for illumination are installed vertically surrounding the display board, and at least a part of the E1 light-emitting elements is positioned in front of the display board. What are the characteristics of h! By providing a method for illuminating a device panel, all of the problems of the conventional illumination methods described above from the first to third points are solved.

尚、図中の符号６は窓ガラスである。What is not indicated by the reference numeral 1 in the figure is a display plate, which can be formed to have an angle of 1° suitable for transmitted illumination, as in the conventional example. This display board 1 is also provided with a light source 2 as in the conventional example, but according to the present invention, the light source 2 is
It is an L (electronic luminescence) light emitting element, and is disposed on the inner surface of the outer case 3 in close contact with the display board 1 so as to be perpendicular to and surrounding the display board 1. , at least a part of which is on the front side (reading side) of the display board 1
It is located at °. Incidentally, the size of the light source 2 disposed on the back side of the display board 1 may be an appropriate size depending on the purpose of illumination, and when the display board 1 is not for transmitted illumination, It is also possible to omit the arrangement altogether. By doing so, the display board 1 can be illuminated by the lighting method of the display board 1 of the present invention.
When there is a need for transmitted light black, the purpose can be achieved by extending the light source 2 to the back side of the display board 1; Since the disposed portion of the light [2] directly illuminates the pointer 4, there is no need to provide any gap provided in the conventional example, and therefore the eaves 5 can also be made extremely small.
In addition, the code|symbol 6 in a figure is a window glass.

3. In the lighting method for the display section, an EL (electroluminescence) light emitting element for illumination is provided on at least one side around the display board of the t11 instrument panel display section so as to surround the display board substantially perpendicularly to the display board. , and at least a part of the E1 light emitting element is located on the curved side of the display panel, thereby eliminating the need for an illumination ring due to the surface light source effect of the EL light emitting element. By positionally overlapping the light source on the rear side with the outer case and eliminating the gap, the light source on the back side, which had to be provided in This kind of 81 panel display section has been put to practical use by solving all the conventional problems, such as not generating heat from an incandescent light bulb as a light source, and making it possible to form a large part on an extremely ordinary part H, making it inexpensive. It has an excellent effect that greatly enhances the above performance.
