Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nameplate attached to the surface of various electronic devices.

[0002]

2. Description of the Related Art Conventionally, nameplates have been attached to the surface of various electronic devices in order to operate the electronic devices and display the current operating state of the electronic devices.

In this type of nameplate, a non-translucent paint is usually printed on substantially the entire front or back surface of a translucent sheet, and a predetermined shape / pattern is not printed at a predetermined position. The translucent display part to be formed is provided and comprised.

FIG. 5 is an enlarged side cross-sectional view of a main part showing a portion of a translucent display portion 81 of a conventional nameplate 80 of this type. As shown in the figure, a portion of the nameplate 80 where the translucent display portion 81 is provided has a printing layer 85 made of non-translucent paint printed on the back surface of the translucent sheet 83. shape·
The translucent display portion 81 is formed by forming a portion on which the printed layer 85 made of a pattern is not printed.

A light emitting element 87 is disposed on the back surface side of the translucent display portion 81, and the light emitting element 87 is caused to emit light so that the portion of the translucent display portion 81 is illuminated brightly on the front surface side of the nameplate 80.

By the way, the translucent display section 81 needs to illuminate it uniformly, but on the other hand, there is a demand for reducing the number of light emitting elements 87 as much as possible.

In order to uniformly illuminate the translucent display portion 81 having a large area with a small number of light emitting elements 87, a mat for light diffusion is conventionally provided on the translucent display portion 81 as shown by a dotted line in FIG. 5, for example. The medium print layer 91 was printed.

[0008]

However, since the matte medium printed layer 91 is thin, a single layer cannot sufficiently diffuse light. Even if another matte-medium printed layer is further printed directly on the matte-medium printed layer 91 to form a multi-layer structure, the mat-medium printed layer 91 has a surface irregularity exposed to the air, which is particularly effective in scattering light. Therefore, the light diffusion effect is hardly increased by this multilayer structure in which the number of the surfaces is not increased.

Therefore, it is conceivable to attach a diffusion sheet or attach a diffusion molding resin to the back surface of the mat medium printing layer 91. The diffusion sheet is a resin sheet mixed with a diffusing material, and the diffusion molding resin is a molding resin mixed with a diffusing material.

However, even if a diffusion sheet or a diffusion molding resin is directly attached to the back surface of the matte medium printing layer 91, the light diffusion effect does not increase so much in the case of a light source whose thickness is relatively small. That is, the thickness increases and the degree of light diffusion increases, but conversely, the increased diffusing agent hinders light transmission.

Further, since the diffusing sheet is expensive, it is necessary to attach the small pieces to the back surface of each translucent display portion 81, but this makes the manufacturing operation complicated. In particular, when there are many places to attach the diffusion sheet or the diffusion molding resin, the workability thereof becomes much worse than that of the printing means such as the matte medium printing layer. Further, when the place where the diffusion sheet or the like is attached is small, there is a problem such as displacement.

The present invention has been made in view of the above points, and an object thereof is to provide a nameplate which can effectively diffuse light, is low in cost, is thin, and is easy to manufacture.

[0013]

In order to solve the above problems, the present invention provides a sheet-like nameplate mounted on the surface of various electronic devices, which comprises a translucent display portion provided at a predetermined position of the nameplate. In a nameplate having a structure in which the surface of the nameplate is illuminated by the light of a light-emitting element disposed on the backside of the nameplate, the nameplate is a translucent sheet, and a desired printing is performed on the front or back surface of the sheet and its predetermined position. A printed layer having a light-transmitting display portion that allows light of a predetermined shape and pattern to pass through, a first matte-medium printed layer printed on the back surface of the portion of the sheet provided with the light-transmitting display portion, and the first matte-medium A translucent auxiliary sheet disposed on the back side of the printing layer, and a second mat-medium printing layer printed on the front surface or the back surface of the auxiliary sheet at a position corresponding to the first mat-medium printing layer. Is configured

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is an enlarged side sectional view showing an essential part of a nameplate 1 according to an embodiment of the present invention.

As shown in FIG. 1, the nameplate 1 has a translucent sheet 10, a printing layer 15 printed on the back surface of the sheet 10, and the printing layer 15 provided at predetermined positions on the printing layer 15. A translucent display section 20 which is provided by the absence of the translucent display section, a first matte-medium printed layer 25 printed on a portion where the translucent display section 20 is provided, and an adhesive layer 30 provided around the translucent display section 20. A translucent auxiliary sheet 40 in which an air layer 35 having a thickness of the adhesive layer 30 is provided between the adhesive layer 30 and the first matte medium printing layer 25 by being attached to the back surface of the adhesive layer 30.
And a second mat-medium printing layer 45 printed on the auxiliary sheet 40 at a position corresponding to the first mat-medium printing layer 25. Below this nameplate 1
The structure will be described in detail by explaining its manufacturing method.

2 to 4 are perspective views showing essential parts of the manufacturing process of the name plate 1. As shown in FIG. In order to manufacture the nameplate 1, first, refer to FIG.
As shown in FIG. 3, a transparent synthetic resin sheet 10 made of polyethylene terephthalate, for example, is prepared, and a desired printing layer 15 is printed on the back surface (upper side surface of the figure).

The printing layer 15 is made of a non-translucent printing material, and has a predetermined shape and pattern (characters "timer" in the figure) at a predetermined position thereof.
The translucent display section 20 is formed by forming a portion where 5 is not printed.

The print layer 15 may have a single layer or a multi-layer structure. The printing layer 15 may be printed on the front surface side of the sheet 10 or on both front and back surfaces. In addition, a light-transmitting paint may be applied onto the light-transmitting display section 20.

Next, as shown in FIG. 3, a first matte medium printing layer 25 is printed on the transparent display portion 20 of the printing layer 15 so as to cover the transparent display portion 20.

The first matte-medium printed layer 25 is made by mixing a diffusing material in the paint, and specifically, a matting material (silica grains having a rough grain shape) is put in the paint and coated. The surface of the film is provided with a characteristic that it is finished like a ground glass to scatter (diffuse) light.

Next, as shown in FIG. 4, an adhesive layer 30 is attached to the peripheral portion of the printed layer 15 where the first matte medium printed layer 25 is provided. The thickness of the adhesive layer 30 is made thicker than the thickness of the first mat medium printing layer 25.

On the other hand, as shown in FIG. 4, a transparent auxiliary sheet 40 made of, for example, polyethylene terephthalate and having the same shape as the sheet 10 is prepared, and the back surface (the upper side surface of the figure) of the first matte medium printing layer is prepared. A second mat-medium printing layer 45 made of the same material as the first mat-medium printing layer 25 is printed on a portion corresponding to 25.

The auxiliary sheet 40 is attached to the adhesive layer 3
By pasting on 0, both are integrated. This completes this nameplate 1.

FIG. 1 shows a cross section of the name plate 1 manufactured as described above taken along the line AA in FIG.

In the above embodiment, as shown in FIG. 1, the thickness of the adhesive layer 30 is set to the first matte medium printing layer 25.
Since the thickness is larger than the thickness of the first matte medium printed layer 25 and the auxiliary sheet 40, a thin air layer 35 is formed.

Below the translucent display portion 20 of the nameplate 1 constructed as described above, the light emitting element 50 is arranged as shown by the dotted line.

When the light emitting element 50 emits light, the light is first diffused by the second mat medium printed layer 45, then transmitted through the auxiliary sheet 40 and introduced into the air layer 35. Then, the diffused light is diffused again in the first matte medium printing layer 25, then passes through the sheet 10, and is emitted from the surface of the nameplate 1.

That is, in the present invention, the light emitted from the light emitting element is diffused independently in both the first matte medium printing layer 25 and the second matte medium printing layer 45. The degree becomes large, and it becomes possible to uniformly illuminate the translucent display section 20 having a large area by the small number of the light emitting elements 50. Moreover, since the light emitted from the light emitting element only passes through the two thin mat medium printing layers 25 and 45, the light transmittance is not hindered, and the amount of light emitted from the front side of the translucent display unit 20 is reduced. Many can keep the brightness bright.

Although the second matte medium printing layer 45 is printed on the back surface side of the auxiliary sheet 40 in the above embodiment, it may be printed on the front surface side.

Although the air layer 35 is formed by providing the adhesive layer 30, the air layer 35 is, for example, the printing layer 15.
It may be formed by interposing a spacer film between the auxiliary sheet 40 and the auxiliary sheet 40.

The air layer 35 is not always necessary, and the auxiliary sheet 4 can be directly attached to the first matte medium printing layer 25.
Even if 0 is touched, the first matte medium printed layer 2
As long as the unevenness of the surface of No. 5 is not hindered, the same effect is produced. In this case, it is preferable to increase the thickness of the auxiliary sheet 40 by a thickness corresponding to the thickness of the air layer 35.

[0032]

As described in detail above, the present invention has the following excellent effects. Although the thickness is thin, the light can be sufficiently diffused and even a small number of light emitting elements can uniformly illuminate a translucent display portion having a large area.

The light transmissive display portion can be illuminated brightly without impeding the light transmission.

Since it is manufactured by simply superposing one sheet on which the printing layer or the like is printed and one auxiliary sheet on which the second matte medium printing layer is printed, the manufacturing operation is easy and the cost can be reduced. .
