Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape cassette used in a magnetic recording / reproducing apparatus.

[0002]

2. Description of the Related Art Generally, as shown in FIGS. 3 and 4, a tape cassette used in a magnetic recording / reproducing apparatus such as a video tape recorder covers a tape pull-out opening in the front portion of a cassette body 20 and is a stretched tape. A lid 21 for protecting 23 is provided. The lid body 21 is made of synthetic resin and is formed in a U shape as a whole, and both side pieces are pivotally supported on both side portions of the cassette body 20 by shafts 22 made of synthetic resin.

In the figure, 24 and 25 are reels. When the tape cassette is set in the magnetic recording / reproducing apparatus, the lid 21 is rotated upward so that the tape 23 can be associated with the magnetic head.

[0004]

In the tape cassette having the above construction, when the tape cassette is accidentally dropped on the floor or the like, the lid body 21 and the pivot shaft 22 thereof, which are the mechanically weakest parts, are damaged. For example, when a drop test was performed in which the iron plate was naturally dropped from a height of 1 m, the lid 21 was damaged.

The present invention has been made in view of the above conventional problems, and an object of the present invention is to provide a tape cassette in which the lid body is not easily damaged even when an impact is applied.

[0006]

In order to achieve the above object, the first object of the present invention is to provide a buffer member on the inner surface of the lid body that abuts against the front portion of the cassette body. . A first problem solving means of the present invention is configured such that a reinforcing portion is provided inside a corner portion of a U-shaped lid body.

[0007]

In the structure of the first problem solving means, when a shock is applied to the lid of the cassette, the cushioning material inside the lid cushions the shock and prevents damage to the lid.

Further, in the structure of the second problem solving means, since the corner portion of the lid body which is most easily damaged when the lid body of the cassette is impacted is reinforced, the breakage at this corner portion is eliminated. .

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

In FIG. 1, reference numeral 1 denotes a cassette body, which has reels 2 and 3 therein, and a wound tape 4 is stretched around a tape pull-out opening 7 through tape guides 5 and 6. At the front part of the cassette body 1, there is provided a lid 8 for covering the tape pull-out opening 7 and the tape 4. The lid 8 is made of synthetic resin, and is entirely U-shaped.
Is pivotally supported on both sides of the tape cassette body 1 by a shaft 10, and the lid 8 is rotatable upward. The portions of the lid body 8 corresponding to both sides of the front portion of the cassette body 1 are
A cushioning material 11 made of felt is adhered and provided, and the cushioning material 11 is brought into contact with the front portion of the cassette body 1. Further, the reinforcing portion 12 is provided inside the corner portion of the lid body 8. The reinforcing portion 12 is formed by adhering members or thickening them.

In the tape cassette having the above-mentioned structure, the lid 8 rotates upward when set in the magnetic recording / reproducing apparatus to associate the tape 4 with the magnetic head. Normally, the lid 8 pulls out the tape. The opening 7 is covered and the tape 4 is protected.

When a shock is applied to the lid body 8 by dropping the tape cassette, the cushioning material 11 located between the lid body 8 and the front portion of the cassette body 1 absorbs the shock, so that the lid body 8 is damaged. Hateful. Further, when the lid body 8 is repeatedly opened and closed, abrupt friction and impact between the lid body 8 and the cassette body 1 can be alleviated, and generation of shavings of the synthetic resin material can be prevented. Furthermore, the impact on the shaft 10 that pivotally supports the lid body 8 is mitigated, and the shaft is prevented from being broken. Further, when the tape cassette is dropped, stress concentrates on the corner portion of the lid body 8, but since the corner portion of the lid body 8 is reinforced by the reinforcing portion 12, the corner portion is not damaged. Of course, since the lid body 8 is not easily damaged as described above, the extremely thin tape 4 located inside the lid body 8 is not damaged by a broken piece or the like. Although the cushioning material is made of felt in the embodiment, it may be made of rubber, synthetic rubber or elastic synthetic resin material.

[0013]

As is clear from the description of the above embodiment, since the tape cassette of the present invention has the cushioning material provided inside the lid, the tape cassette may be dropped or otherwise impacted by the shock. Also, the cushioning material cushions the impact and prevents the lid from being damaged. In addition, a reinforcing part is provided inside the corner of the lid to protect the corner of the lid, which is particularly liable to be damaged, and also to prevent breakage of the pivot shaft of the lid and protect the tape. Its practical value is great, such as being damaged.
