In recent years, it has been called out that it is necessary to consider recyclability of resin molded products used for industrial products. However, when a resin material is recycled, there are problems such as strength, hue, and deterioration of the material, and it is difficult to introduce the resin material into an electronic device in which appearance is prioritized. In particular, in the case of a resin material, since problems such as sink marks and welds tend to appear on a wide flat surface, it is important for an electronic device in which this flat surface is provided at a position of a housing to be seen by a user. Is an important issue.

For example, in a conventional example of a television receiver or a word processor, a wide flat housing surface formed on a peripheral side surface of a main housing or on a surface of a thin shape in a housed state is seen by a user. That is, in order to enhance the design of the flat casing surface, it is necessary to take measures more than the above-described conventional example.

On the other hand, in the case of industrial products using metal materials, it is necessary to consider resource reduction. But,
In the above-mentioned conventional example, when the metal plate is made thinner corresponding to a small amount of resources, there is a problem in terms of distortion and strength. In order to solve these problems, it is necessary to take measures more than the above-mentioned conventional example.

Further, in the above-mentioned conventional example, the user is provided with a high-tech feeling and a gorgeous feeling by providing a wide flat housing surface. However, the broad flat surface, on the other hand, has a strong impression of minerals, is familiar to humans,
It has an aspect that can not be called a modeling process with a more intimate feeling. In particular, when light hits a wide flat surface, the reflected light reflected on this flat surface enters the eyes of the user in a straight line, giving a sharp impression, but it is not a human-friendly modeling process. It is. Moreover, the reflected light reflected on a flat surface is
Slight distortion of a flat surface is further promoted.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a main object of the present invention is to provide a surface treatment which is gentle to the human eye, has less noticeable distortion, and further has a steel property. An object of the present invention is to provide a device housing structure.

[0011]

According to the present invention, in order to solve the above-mentioned problems, a large pattern having an appropriate size of a substantially square shape is provided on a flat housing surface arranged at a position where the user can see. An uneven pattern in which the uneven portions are uniformly continuous is formed. At this time, the size of the width PW of the uneven portion and the depth PD of the unevenness is 10 mm ≦ PW ≦ 150 mm, and 1
/ 5PW ≦ PD ≦ 1 / 15PW. In a good case, the uneven portion is formed by combining a plurality of surfaces.

In this case, the housing surface may be formed of a resin material having a substantially uniform thickness or a metal plate.
The uneven pattern formed on the housing surface may be formed leaving a flat surface smaller than the width PW of the uneven portion at an end of the housing surface.

[0013]

According to the present invention, in a housing structure of an electronic device having a flat housing surface at a position where the user can see, a large-sized uneven portion having an appropriate size is formed on the housing surface. By forming a large pattern of concavo-convex patterns, the flat casing surface is divided into a plurality of parts by the concavo-convex portions, so that the strength can be increased and the surface distortion can be made less noticeable. At this time, by setting the size of the width PW and the depth PD of the unevenness to the size of a large pattern having an appropriate size corresponding to the size of the housing surface, the steel is enhanced, and the distortion of the surface is less noticeable. Meanwhile, the range in which a good design can be obtained is set. Furthermore, the three-dimensional appearance of light and shadow can be obtained by the concave and convex portions on the case surface provided with the concave and convex portions, and the reflected light can be obtained in a rhythmical manner by changing the concave and convex portions.

Further, by forming the irregularities in combination with a plurality of surfaces, it is possible to further enhance the steel property, make the surface distortion less noticeable, and obtain rhythmical and reflected reflected light.

Further, by forming the casing surface with a resin molded product having a substantially uniform thickness, sink marks and welds can be made less noticeable. Furthermore, by forming the housing surface with a metal plate formed with a substantially uniform thickness, the flat housing surface is divided into a plurality of portions by the uneven portions, so that color unevenness due to painting is less noticeable, and moreover, from electronic devices. The generated electromagnetic wave can be diffused on the divided housing surfaces to reduce the obstacle caused by the electromagnetic wave.

Further, the size of the concavo-convex pattern is made equal to that of the case surface by forming a flat surface smaller than the width PW of the concavo-convex portion at the end of the case surface. Since there is no need, the size of the concave and convex portions can be set freely within the range of the set size.
