Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape cassette storage case for storing a tape cassette.

[0002]

2. Description of the Related Art In recent years, video cameras and the like using a tape cassette as a recording medium have been increasingly miniaturized and can be easily carried. For this reason, opportunities to use a video camera or the like outdoors or the like are increasing, and accordingly, a tape cassette as a recording medium is often carried.

[0003] The tape cassette is usually carried and stored in a case stored in a case. As a case for accommodating a tape cassette, see, for example,
In order to protect the tape cassette from an impact caused by dropping while carrying it, as in a tape cassette case disclosed in Japanese Patent No. 5585 and a tape cassette storage case disclosed in Japanese Patent Application Laid-Open No. 10-258890. There has been proposed a structure in which a cushioning material is provided inside a case so that the shock or the like caused by dropping is absorbed by the cushioning material.

[0004]

However, in recent years,
2. Description of the Related Art Video cameras and the like have been widely used as consumer devices even in ordinary households. Such a tape cassette used for a consumer video camera or the like is assumed to be used under a more severe use environment. Therefore, it is desired that the case for accommodating the tape cassette can reliably protect the tape cassette even under such a severe use environment.

A case for a tape cassette disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 5-85585,
The tape cassette storage case disclosed in Japanese Patent No. 58890 discloses a tape cassette housing case in which four corners of a tape cassette housed in a case are brought into contact with a cushioning material provided in a corner portion inside the case to cause a drop or the like. In addition, the shocks applied to the four corners of the tape cassette are absorbed by these cushioning materials. However, when a large impact is applied, it may be difficult to reliably absorb the shocks by these cushioning materials. .

Further, in the case having the above-described structure, when it is intended to surely absorb the large impact applied to the four corners of the tape cassette by the cushioning material provided at the corner inside the case, the cushioning material is required. It is necessary to increase the elastic absorption of the rubber. If the elastic absorption of the cushioning material is increased, the holding force for holding the tape cassette is reduced by the cushioning material, and when the case is opened due to an impact such as dropping, the tape cassette jumps out of the case and damages the tape cassette. It may be done.

Conventionally, when a cushioning material is mounted inside a case, as disclosed in Japanese Patent Application Laid-Open No. 10-258890, a method of insert-molding a cushioning material into a case and incorporating the cushioning material into a case may be used. It is common to adopt a method of attaching the cushioning material by performing secondary processing such as sonic welding, and such a complicated process has been a factor of increasing the manufacturing cost of the case.

The present invention has been made in view of the above-mentioned conventional circumstances, and has a structure which can be manufactured at a relatively low cost and has a highly reliable tape which can reliably protect a tape cassette. It is intended to provide a cassette storage case.

Specifically, since the length L1 in the longitudinal direction of the tape cassette 100 is 65 mm, the length L2 in the longitudinal direction of the concave portion 21 is set to 65.2 mm, and the higher projections 23 facing each other between the pair of peripheral walls. Is set to 64.6 mm.

By setting the dimensions of the recess 21 and the plurality of protrusions 23 formed on the peripheral wall thereof as described above,
When the tape cassette 100 is placed in the concave portion 21, three of the plurality of protrusions 23 formed on the peripheral wall of the concave portion 21 located at the center of a pair of peripheral walls along the width direction of the concave portion 21. Each of the projections 23a is pushed in by 0.2 mm and elastically displaced,
00 will be in contact with the side portion in the width direction. And
The holding force acts on the tape cassette 100 by the elastic displacement of the three opposing projections 23a, and the tape cassette 100 is held by being sandwiched by the three opposing projections 23a. become. The other protrusions 23 have their apexes facing the side surface of the tape cassette 100 with a small gap therebetween, so that the protrusions 23 do not adhere to the side surface of the tape cassette 100 and Cassette 100

So
For example, the second elastic body 30 can be easily attached without performing a complicated process such as insert molding or ultrasonic welding.

By the way, as shown in FIG. 9, the first elastic body 20 is fitted on the inner peripheral side of the main body 11 of the outer casing 10, and its upper end face is located on the upper side of the main body 11. The thickness is set so as to slightly protrude from the end surface, that is, the surface of the main body 11 that abuts against the lid 13. Specifically, the first elastic body 20 is
When the outer casing 1 is fitted on the inner peripheral side of
The thickness of the first elastic body 20 is set so that the amount of protrusion H of the first elastic body 20 from the upper end surface of the main body 11 at the upper end surface side becomes, for example, 0.2 mm.

As described above, when the first elastic body 20 is fitted to the inner peripheral side of the main body 11 of the outer casing 10, the first elastic body 20
The upper end surface side of the elastic body 20 is the main body 11 of the exterior housing 10.
If the tape cassette storage case 1 is closed, the outer casing 10 can be slightly protruded from the upper end face of the external cassette 10.
Before the main body 11 and the lid 13 abut against each other, first, the upper end face of the first elastic body 20 and the upper end face of the second elastic body 30 come into contact with each other. In this state, a pressing force is applied in a direction in which the main body 11 and the lid 13 of the exterior housing 10 abut against each other, and the upper end face of the first elastic body 20 and the upper end face of the second elastic body 30 are moved. By slightly elastically displacing, the main body 11 and the lid 13 of the exterior housing 10 abut against each other, and the tape cassette storage case 1 is closed. If the upper end surface of the first elastic body 20 and the upper end surface of the second elastic body 30 are elastically displaced when the tape cassette storage case 1 is closed, the tape The sealing performance of the storage section in which the cassette 100 is stored is improved, and the reliability of the tape cassette 100 for long-term storage is improved.

In the above, when the first elastic body 20 is fitted to the inner peripheral side of the main body 11 of the outer casing 10, the first elastic body 20
The upper end surface side of the elastic body 20 is the main body 11 of the exterior housing 10.
An example in which the second elastic body 30 is slightly protruded from the upper end surface of the outer casing 10 has been described.
3, the same effect can be obtained even when the upper end face of the second elastic body 30 slightly projects from the upper end face of the lid 13 of the exterior housing 10 when fitted on the inner peripheral side of the third elastic body 30. Will be done.

According to the tape cassette storage case according to the present invention, the tape cassette stored in the storage portion is covered by the first and second elastic members over the entire outer periphery thereof. When a large impact is applied, the impact can be effectively absorbed by the first and second elastic bodies, and the tape cassette can be effectively protected. In particular, since a plurality of projections are provided on the peripheral wall of the concave portion of the first and second elastic members, the impact applied to the tape cassette due to the elastic displacement of the plurality of projections is dispersed to ensure protection of the tape cassette. It can be.

Further, the tape cassette storage case holds the tape cassette by elastically displacing at least a part of the plurality of projections provided on the peripheral wall of the concave portion of the first elastic body and the second elastic body. Therefore, not only is the tape cassette storage case maintained when the tape cassette storage case is closed, but also when the tape cassette storage case is opened due to an impact such as dropping, the tape cassette is moved to the tape cassette storage case. The inconvenience of jumping out of the storage case and damaging the tape cassette can be effectively suppressed.
