BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic tape cassette storage case, and more particularly to an improvement in a magnetic tape cassette storage case used for storing a plurality of audio magnetic tape cassettes.

[0002]

2. Description of the Related Art Conventionally, when storing or carrying a magnetic tape cassette used in audio equipment or the like,
The magnetic tape cassette is housed in a plastic magnetic tape cassette storage case (hereinafter simply referred to as “cassette storage case”). The cassette storage case has a structure that covers the entire cassette, has a dustproof effect and an impact reducing effect, and has an excellent function of protecting the cassette. Particularly, in the case of a compact audio cassette in which an opening for inserting a magnetic head is provided on the front surface of the cassette, a finger or the like is easy to touch the surface of the magnetic tape, and a cassette storage case is indispensable when carrying.

By the way, in the case of a magnetic tape cassette containing classical music or the like which is generally commercially available, long music is divided into two or more magnetic tape cassettes, for example, as recorded on two or more record boards. Recorded
Provided as a set. However, the conventional cassette storage case can store only one magnetic tape cassette, and a general user needs to store one set of tapes so that they do not fall apart, which is very inconvenient.
In particular, language study tapes and the like must be stored in accordance with the study program, and the fact is that a special storage box is used.

A cassette storage case capable of storing a plurality of such magnetic tape cassettes at the same time is disclosed in Japanese Utility Model Publication No. 57-52781 and Japanese Utility Model Publication No. 60-16541.
No. 59-118874 and 59-118168.
No. 59-189778, No. 59-189779,
And JP-A-63-137787.
These cassette storage cases are composed of a plurality of integrally formed storage portions and a pair of lids provided to be openable and closable to close each storage portion. They are stored alternately in parallel.

[0005]

However, such a cassette storage case for simultaneously storing a plurality of magnetic tape cassettes as described above is formed by a structure in which almost conventional single-unit cassette storage cases are stacked. Therefore, there is a problem that a large storage space is required. That is, in the case of a cassette storage case in which a set of magnetic tape cassettes is stored so as to overlap in parallel in the same direction, the interval between the opposing lid walls is an increased thickness portion of the stored magnetic tape cassette. It is configured with an interval corresponding to twice the thickness of the trapezoid. or,
Even in the case of a cassette storage case for storing a set of magnetic tape cassettes in a staggered manner so as to overlap one another in parallel, the distance between the opposing lid walls is limited by the thickness of the trapezoidal portion of the magnetic tape cassette to be stored. It is configured to have an interval corresponding to the thickness obtained by adding the thickness of the portion excluding the trapezoidal portion. Therefore, the thickness of such a cassette storage case is configured to be considerably larger than the cassette thickness excluding the above-mentioned cassette thickness increasing portion. Generally, these cassette storage cases are stored side by side so that the back label can be seen, so that a large storage space is required if the cassette storage case is thick.

[0006] That is, an object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide a cassette storage case which accommodates a plurality of magnetic tape cassettes, and which is thin and easy to store.

[0007]

SUMMARY OF THE INVENTION The object of the present invention is to provide a pocket member for accommodating an end portion of a magnetic tape cassette, and first and second casing members having rotation preventing projections. In the magnetic tape cassette storage case which can be opened and closed by the pivotal portion of the portion, the thickness of the inside of the pocket member is staggered back and forth so that the thickness increasing portions do not overlap with the other magnetic tape cassette. The present invention is achieved by a magnetic tape cassette storage case, which is formed to have a thickness enough to store a plurality of combined magnetic tape cassettes.

The object of the present invention is that the thickness of the inside of the pocket member is staggered back and forth so that the thickness-increasing portions do not overlap with the other magnetic tape cassette.
The thickness of the first magnetic tape cassette located on the inner wall side of the pocket member on the side of the first casing member is set to a thickness just for accommodating the thin part of the magnetic tape cassette. And a second recess for receiving a thickened portion of the second magnetic tape cassette located on the second casing member side.
The present invention can also be achieved by a magnetic tape cassette storage case, wherein the recess is formed near the open / close end of the second casing member.

The cassette storage case of the present invention is not limited to the configuration of the above-described embodiment, but can be variously modified. For example, three magnetic tape cassettes may be stored. In this case, it is necessary to increase the inner width of the pocket member and to provide a concave portion for receiving the cassette thickness increasing portion at a position facing the pocket member, but the casing member does not need the concave portion.

When four magnetic tape cassettes are to be stored, the inner width of the pocket member need only be twice the inner width described in the above embodiment. That is, although the odd-numbered magnetic tape cassettes are stored and the even-numbered magnetic tape cassette cassettes are stored in different recess formation positions for receiving the cassette thickness increasing portions, the same thinness as described above can be achieved. it can.

Further, in each of the above embodiments, the front end and the rear end of the plurality of magnetic tape cassettes are accommodated in the pocket members. You may comprise so that it may open in a longitudinal direction.
