Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic equipment casing for constituting various electronic equipment such as a tape recorder device and a disc player device.

[0002]

2. Description of the Related Art Conventionally, there have been proposed electronic devices which record and reproduce information signals such as audio signals and video signals using a tape cassette or a disk cartridge as a recording medium. Such an electronic device has an electronic device housing, and is configured by housing an electronic substrate and various mechanical parts in the electronic device housing.

In the electronic equipment casing, the tape cassette and the disk cartridge can be inserted into and taken out of the electronic equipment casing. Therefore, as shown in FIGS. Some have a lid 102 that is supported and can be opened and closed.

The lid 102 includes a pair of hinge pieces 103.
have. These hinge pieces 103 have A in FIG.
As shown in FIG. 10 which is a cross-sectional view taken along line A of FIG.
1. A support hole 10 into which a pair of support shafts of 1 are fitted correspondingly.
4 is drilled.

When the lid portion 102 is attached to the body portion 101, the hinge piece 103 is inserted into a hinge piece insertion hole 108 provided in the body portion 101 and the hinge piece insertion hole 108. It is bent in a direction away from a support shaft that is provided inside. Then, when the hinge piece 103 returns to the initial state, the support shaft is fitted into the support hole 104 and is rotatably supported with respect to the support shaft.

The hinge piece 103 has a plurality of ridges so that the hinge shaft 103 does not fall off the hinge shaft 103 due to inadvertent bending after the shaft is fitted into the support hole 104. Ribs 105 are provided. In addition, the hinge piece insertion hole 108 is provided with an inner wall portion and the hinge piece 103 in order to prevent the hinge piece 103 from falling off the support shaft.
It is formed so that the space between and is as narrow as possible.

Inside the main body 101, as shown in FIG. 11 which is a sectional view taken along line BB in FIG.
6 is stored. The bar antenna 107 and various other electronic elements are arranged on the electronic substrate 106. The bar antenna 107 and the electronic element do not come into contact with the hinge piece 103.

[0008]

By the way, in the electronic equipment casing as described above, the hinge piece 103 is
Since the ribs 105 are provided so that the ribs 105 are not easily bent, the ribs 105 are prevented from falling off the spindle. Further, the hinge piece 103 has a narrow gap between itself and the inner wall of the hinge piece insertion hole 108.
It is prevented from falling off from the shaft.

Therefore, when the hinge piece 103 is attached to the support shaft, the hinge piece 103 is not easily bent, and the gap between the hinge piece 103 and the inner wall of the hinge piece insertion hole 108 is narrow, which makes the attachment work difficult. Has become.

Further, when the lid 102 is removed from the main body 101, which is necessary for repair or the like, the hinge piece 103 is difficult to bend, and a gap is formed between the hinge piece 103 and the inner wall of the hinge piece insertion hole 108. Is very difficult due to its narrow size. When the hinge piece 103 is detached from the support shaft, the hinge piece 103 is deformed into an unreasonable shape, so that the rib 105 is crushed or plastic deformation such as whitening of the hinge piece 103 occurs. Therefore, the lid 102 cannot be reused.

It should be noted that it is conceivable that the easiness of bending of the hinge piece 103 is set to an appropriate degree by appropriately setting the height of the rib 105, but in this case,
This makes it difficult to design and manufacture the hinge piece 103.

[0012] Therefore, the present invention is proposed in view of the above-mentioned circumstances, and is an electronic equipment casing having a lid portion rotatably attached to a main body portion, the lid portion It is easy to attach and detach the lid portion to and from the main body portion without causing difficulty in designing and manufacturing the hinge piece to be installed in the hinge piece, and when removing the lid portion from the main body portion. An object of the present invention is to provide a housing for electronic equipment in which plastic deformation of the hinge piece is prevented.

[0013]

In order to solve the above-mentioned problems and achieve the above-mentioned objects, a housing for electronic equipment according to the present invention comprises:
The hinge includes: a main body portion; and a lid portion that has a hinge piece and is rotatably supported by the rotation support portion of the main body portion and rotatably attached to the main body portion. The piece is configured such that a member mounted on the electronic board housed in the main body portion prevents the piece from falling off the rotation support portion.

Further, according to the present invention, in the electronic equipment casing, the member for preventing the hinge piece from falling off the rotation support portion is an antenna holder for holding a bar antenna. .

[0015]

In the electronic equipment casing according to the present invention, the lid portion is rotatably supported by the rotation supporting portion of the main body portion, and the lid portion is rotatable with respect to the main body portion. Since the hinge piece to be attached is prevented from coming off from the rotation support portion by a member attached on the electronic board housed in the main body portion, the engagement state with the rotation support portion is shallow. Even if it is, it will not fall off from the rotation support portion.

Further, in the case for the electronic equipment, when the member for preventing the hinge piece from coming off from the rotation support portion is an antenna holder for holding the bar antenna, the rotation support portion is It is possible to reliably prevent the hinge piece from falling off.
