[0002]

2. Description of the Related Art In general, a television receiver has an image display unit (hereinafter, referred to as a CRT), a control circuit unit, and an exterior body for housing these components.

The exterior body of a conventional television receiver is shown in the horizontal sectional view of FIG. In the figure, the exterior body 30
Is composed of two front and rear parts made of synthetic resin, that is, a front cabinet 31 and a rear plate 32.
1, a bottom plate 33, a side plate 34 and a front part of a top plate (not shown) are integrally formed, and a rear plate 32 is integrally formed with the bottom plate 33, the side plate 34 and a rear part of the top plate. The front surface cabinet 31 and the rear surface plate 32 are configured to be externally mounted on the CRT 35 and the control circuit portion 36 by, for example, screwing the front cabinet 31 and the rear surface plate 32 together.

The front cabinet 31 has a CR
The front opening 3 is formed by forming the exposure opening 37 of T35.
On the inner peripheral surface of No. 1, ribs 40 to be mounted via mounting bolts 39 are integrally formed on the mounting fittings 38 arranged at the four corners of the CRT 35.
Reinforcing ribs (not shown) are formed to support the weight of the RT 35.

[0005]

In the case of discarding the exterior body 30 of the conventional television receiver described above,
The front cabinet 31 and the rear plate 32 are removed, but the exterior body 30 is composed of two parts, the front cabinet 31 and the rear plate 32, and each part integrally forms a part of the bottom plate, the side plate, and the top plate. Therefore, one component is large and difficult to handle, distribution cost increases, and since the ribs 40 are formed on the front cabinet 31 to improve the strength, they are not easily deformed at the time of disposal.

Further, since an additive for preventing combustion and improving flowability is added to the synthetic resin, harmful substances are liable to be generated when burned as it is and recovered as heat energy. , Special treatment must be done.

In the case of further heating and melting and reforming,
Due to the influence of the additive material, the quality of the product is deteriorated (for example, the strength is insufficient).

As described above, the exterior body 30 has a problem that it is difficult to handle and reuse it as it is.

Further, as another conventional technique, there is one in which an outer body is formed of a metal (for example, iron) in consideration of reuse, but after forming by bending and drawing, painting is performed as a countermeasure against surface corrosion. However, there is a problem that the cost is high and the solvent contained in the coating causes environmental damage. Further, since the metal piece in the opening for exposing the CRT on the front plate is discarded, the yield of the material is poor and the television receiver is expensive. Furthermore, since a frame formed by bending an iron plate was provided to support the CRT,
It was a very heavy and expensive television receiver.
