[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage case for a cassette half, and more particularly to a storage case for a cassette half which can be stored regardless of the position of a tape running portion of the cassette half.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 1, a cassette half 1 is formed in a rectangular shape in plan view.
A pair of reel holes 2 are formed at a substantially intermediate portion in the short side direction, and one long side is formed as a tape running portion 3, and the vicinity of the tape running portion 3 is formed as a substantially trapezoidal thick portion 4. ing.

[0003] Such a cassette half 1 is
It is stored in a storage case 5 as shown in FIG.

The storage case 5 has a rectangular bottom plate 6a.
Is surrounded by a front plate 6b and a pair of side plates 6c on three sides thereof, and a main body 6 having an opening 6d facing the bottom plate 6a, and the side plates 6c on the remaining one side of the bottom plate 6a. It is constituted by a lid 7 which is rotatably mounted in between and opens and closes the opening 6d.

As shown in FIG. 2, the lid 7 is formed at the pivotal connection side with the main body 6 so as to be bent in a substantially U-shape opening toward the rotation end. A holding section 7a is provided.

Further, when the cassette half 1 is stored at a predetermined position of the bottom plate 6a, the cassette half 1 is inserted into each reel hole 2 of the cassette half 1 and engaged with the reel 8 in the cassette half 1. A pair of reel detents 9 are projected.

In the storage case 5, the thick portion 4 of the cassette half 1 is attached to the holding portion 7a of the lid 7.
2, the cassette half 1 is temporarily stored as shown by a chain line in FIG. 2, whereby the lid 7 is rotated to a position at which the opening 6 d of the main body 6 is closed, whereby the main body 6 is closed. The cassette half 1 is accommodated in a space formed by the cover 7 and the cover 7.

On the other hand, the storage case 5 has a uniform dimension in the thickness direction according to the thickness of the thick portion 4 so that the thick portion 4 of the cassette half 1 can be stored. As a result, the cassette half 1
A gap is formed between a portion other than the thick portion 4 and the storage case 5, whereby the cassette half 1 has a large shape.

However, in recent years, it has been desired to reduce the size of the storage case in the thickness direction in order to enhance the storage performance.

As a specific method, as shown in FIG. 3, a notch 10 corresponding to the thick portion 4 of the cassette half 1 is formed on one of the opposite walls of the holding portion 7a of the lid 7. It is conceivable that the thickness of the storage case 5 may be reduced as a whole by forming a groove 11 on the other side to absorb a dimensional difference between the thick portion 4 and other portions during storage. I have.

[0011]

In the storage case 5 described above, the storage posture of the cassette half 1 is uniquely determined due to the relationship between the notch 10 and the groove 11 and the thick portion 4 of the cassette half 1. When the cassette half 1 is stored, it is necessary to store the cassette half 1 while checking its direction, which makes the storing operation complicated and causes a problem that the storing operation in a dark environment cannot be performed smoothly.

[0012] Therefore, conventionally, it is desired to cope with the above-mentioned inconvenience, and the present invention is intended to solve such a problem which has been conventionally left.
