[Detailed description of the invention] (Field of industrial application) The present invention relates to a storage case for cassette tapes.
In particular, the present invention relates to a storage case for collecting and storing a plurality of cassette tapes.

(Prior art) In the past, the tape width and recording method remained the same as normal cassette tapes (hereinafter referred to as standard cassettes), but small cassette tapes (hereinafter referred to as ``standard cassettes'') in which only the cassette half was approximately 1/3 the size of standard cassettes were developed. There is a small cassette).

As a storage case for small cassettes in which a plurality of small cassettes are stored together, there is a ``cassette tape storage case'' proposed by the present applicant (Utility Application No. 15559/1982).

A feature of this storage case is that its external dimensions are the same as the cassette half of a standard cassette, so it can be easily stored in the storage case (sleeve) of a standard cassette. This storage case is provided with a protrusion that defines the direction of insertion during storage.

(Problems to be Solved by the Invention) In the conventional cassette tape storage case described above, the small cassettes stored in the storage area are fixed with a plurality of ribs on both sides, bottom, and back.
In addition, the reel is fixed by the locking part, and the small cassette is stored in the storage part in such a way that it fits snugly into the storage part, so the small cassette half stored in the storage part and the inside of the storage part Since there is no gap between the cassette and the surrounding surface where you can insert your finger and pick out the small cassette, there are the following problems when taking out the small cassette from the storage part, and there is a disadvantage that it is not easy to take out the small cassette. Ta.

To take out a small cassette without turning the storage case over: While holding the storage case with one hand, use the other hand to grasp the back and front of the small cassette through the notch provided on one side. Pick up the small cassette (on the front side of the cassette) and remove the small cassette by gradually removing the above-mentioned fixation with the storage part of the small cassette, which is fixed with multiple ribs, and pulling it up, but this requires both hands. In addition, since the small cassettes are fixed in the storage part without wobbling, the small cassettes cannot be removed from the storage part unless they are stacked in a well-balanced manner, and it takes time to take them out.

When you turn the storage case over and take out a small cassette, all of the stored small cassettes will fall out towards the opening, making it impossible to take out only the small cassettes you need, and there is also the risk of dropping and damaging the small cassettes. Ta.
