JPH06152175A - Enclosure structure of electronic apparatus and its recycling treatment method - Google Patents

Abstract

PURPOSE:To perform the recycling treatment of an enclosure by a method wherein a structure for supporting a conductive sheet is installed at the enclosure for an electronic apparatus and the conductive sheet can be detached easily from the enclosure. CONSTITUTION:A bottom case 1 is constituted of a conductive sheet 2. Holes which are smaller than protrusion parts 3 are made in positions of the protrusion parts 3 in the conductive sheet 2. When the conductive parts 3 are passed through the holes, the bonding of the bottom case 1 to the conductive sheet 2 is supported by the protrusion parts 3. In the recycling treatment of the bottom case 1, the conductive sheet 2 supported only by the protrusion parts 3 can be detached easily from the bottom case, and the bottom case 1 made of a genuine material can be reused. In addition, a conductive sheet 5 is hooked by claws 6 formed at the bottom case 1, and the bonding of the bottom case 1 to the conductive sheet 5 is supported by the claws 6. When a bottom case 4 is recycled and treated, the conductive sheet 5 supported only by the claws 6 can be detached easily.

Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an electronic device having a conductive sheet for the purpose of electromagnetic noise and the like, and a method of reproducing the same.

[0002]

[Field of Industrial Application] When an electronic device is discarded, the housing can be easily recycled, and the raw material of the housing can be newly reused.

[0003]

2. Description of the Related Art A conventional housing for electronic equipment is disclosed in Japanese Patent Laid-Open No. 1-1.
As described in Japanese Patent No. 88000, a conductive material may be mixed with a pure plastic for the purpose of electromagnetic wave noise or the like, a plating treatment may be performed, or an adhesive may be applied by using the conductive sheet. It is common to have

[0004]

The above-mentioned prior art does not take into consideration the reuse of the raw material for the casing of the electronic equipment, and the ordinary casing is made of a conductive material for the countermeasure against electromagnetic noise, Due to the use of plating and the like, impurities are included, so that there is a problem that the casing cannot be recycled.

When the case is attached to the conductive sheet with an adhesive or the like, in addition to the above problems,
There was a problem that it was difficult to separate the conductive sheet from the conductive sheet during the recycling process of the case.

An object of the present invention is to provide a structure for supporting the conductive sheet in a housing of an electronic device so that the conductive sheet can be easily removed from the housing, The purpose is to make it possible to recycle the casing and reuse the casing material of the electronic device.

[0007]

In order to achieve the above object, a structure for supporting the conductive sheet is provided in a casing of an electronic device, and the conductive sheet can be easily disposed when the casing is discarded. Is removable from the case.

[0008]

By making the casing of the electronic device a structure in which the conductive sheet can be easily removed, the casing can be recycled and the raw material of the casing can be reused. Furthermore, the processing time of the housing is shorter and the material cost is lower than in the case where the housing is attached with the conductive sheet by plating and adhesive.
