DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the display device of the present invention will be described with reference to the drawings. 1A and 1B are views showing an embodiment of the holding member of the present invention, wherein FIG. 1A is a front view, and FIG. 1B is a side sectional view. FIG. 2 is a perspective view showing an embodiment of the display device according to the present invention, in which a plurality of display windows are provided on a panel, and an LED is used as a light emitting member for display.

The holding member has a substantially cylindrical shape and includes a support portion 2, a holder portion 1, and an elastic portion 3. The holder portion 1 has a through hole 101 and a cylindrical outer peripheral portion 102, and has an elastic portion 3 on the upper portion of the holder portion 1, which is integrally formed with a different hardness with a softer hardness than the holder portion and has a thin tip portion. The support portion 2 has a fitting portion 204 on a cylindrical inner wall, and the fitting portion 204 is slidably fitted to the outer peripheral portion 102 of the holder portion 1, and the holder portion 1 is slid by the frictional resistance of the fitted portion. Hold. Support part 2
Has a base portion 203 in contact with the substrate 5, a plurality of (two to three) legs 202 protruding from the base portion 203 and inserted into the mounting holes 501 of the substrate 5, and a snap portion 201 at the tip thereof.

A plurality of display windows 601 are provided on the panel 6, and a boss 7 (not shown) is provided on the back surface of the panel 6. The substrate 5 is inserted into the mounting hole 503 of the substrate 5 so that the light emitting member is positioned opposite the display window 601, and the boss 7 is inserted.
Is screwed into the screw hole 701 with a screw 8. Multiple LEs
In D4, the lead 402 is soldered to the soldering portion 502 of the electronic circuit formed on the substrate 5. A plurality of mounting holes 501 are provided around the soldering portion 502 of the substrate 5 for mounting the holding member.

The holding member is provided in the mounting hole 501 with the support 2.
The legs 202 and the snap portions 201 are inserted against the elasticity, and snap-fitted by the elasticity of the snap portions 201 to be attached to the substrate 5. Even when the LED 4 is bent and attached, the light emitting section 401 is in contact with the inner wall section 101 and the position of the light emitting section 401 deflects the lead 402 so that the light emitting section 401 is corrected.

An embodiment of the display device according to the present invention will be described with reference to cross-sectional views shown in FIGS. The holding member is mounted on the substrate 5 with the leg 202 having a strong elastic force, with the cylindrical outer peripheral portion 102 of the holder portion 1 fitted into the fitting portion 204 of the support portion 2. The holder portion 1 fitted to the support portion 2 has a cylindrical elastic portion 3 made of a flexible material such as a foamed resin integrally molded at the tip of the holder portion 1. The leg portion 202 of the support portion 2 and the snap portion 201 at the tip thereof are inserted into the mounting holes 501 of the substrate 5, the base portion 203 abuts on the surface of the substrate 5, and the elastic snap portion 201 is engaged with the back surface of the substrate 5. And fitted.

The holder section 1 houses the light emitting section 401 of the LED 4 in the through hole 101. The dimension A from the surface of the substrate 5 (the base 203 of the support portion 2) to the tip of the elastic portion 3 is larger than the dimension B from the back of the panel 6 to the tip of the boss 7, and A> B (1 to 2 mm protrusion). The holder A is slid so that the A dimension is adjusted.

When the substrate 5 is inserted through the mounting hole 503 and screwed into the mounting hole 701 of the boss 7 with a screw 8, the inclined surface 301 at the tip of the elastic portion 3 is moved to the panel 6 (or the optical path on the back surface of the display window). Around). The elastic part 3 covers around the optical path of the light emitting part 401 to the display window 601 and is compressed and deformed without light leakage. Light emitting portion 401 of LED 4 held in through hole 101 of holder portion 1
The light from the display does not leak to other display windows.

Even if there is a slight variation in the dimensional difference between A and B, the holder 1 fitted to the support 2 is slid to adjust the slidability so that A> B. When the screw 5 is screwed with the screw 8, the amount of protrusion of the holder 1 is adjusted. Therefore, the holding member is in contact with the back surface of the panel 6 or around the display window 601 in close contact.

According to this embodiment, the display window 60 of the panel 6
Since the elastic portion 3 is in close contact with the periphery of the first optical path, it is possible to prevent light from leaking from the distal end portions of the light emitting member such as an LED and the holding member into the device. Further, since the dimensions of the holding member can be slidably adjusted, the deformation of the panel and the damage to the substrate can be prevented by the holding member when the substrate is assembled to the panel. Further, by preventing light leakage, each display window can prevent light leakage from other LEDs even when a large number of LEDs and light-emitting holes are concentrated on the panel.

[0024]

According to the holding member and the display device of the present invention, it is possible to prevent light leakage from the tip of the holding member to other portions. Further, when the substrate is assembled to the panel, no excessive stress is applied to the panel or the substrate by the holding member, so that deformation of the panel or damage to the substrate can be prevented.
