Description

[Detailed Description of the Invention] The present invention relates to a cassette storage case in which a cassette holding a magnetic tape wound between two reel frames is stored for the purpose of storage or portability.

Recently, ultra-small cassettes called microcassettes (registered trademark), which are smaller than normal-sized cassettes, have come into wide use.

It is often necessary to carry a plurality of cassettes of this type because of recording time, etc. Therefore, there has been a demand for a cassette storage case that is convenient for carrying a plurality of cassettes.

In view of the above points, the present invention aims to provide a cassette storage case that can store two cassettes compactly, has a conveniently portable shape, and is easy to manufacture.

Embodiments of the cassette storage case according to the present invention will be described below with reference to the drawings.

In FIG. 1, the main body bottom part 1 and the lid bottom part 2A, 2
B is integrally molded from synthetic resin (polypropylene), and a hinge portion 3 is provided by forming a groove at the boundary thereof.

Furthermore, main body side parts 4A, 4B folded back at right angles are formed on both sides of the main body bottom part 1, and two pairs of cassette engaging protrusions 5A, 5B, 6A, 6B are integrally formed in the central part, respectively.

Here, the cassette engaging protrusions 5A and 5B have the function of engaging with the winding frame of the first cassette 7 to be stored and preventing the magnetic tape wound around the winding frame in the cassette from loosening.

Similarly, the cassette engaging protrusions 6A, 6B are adapted to engage with the winding frame of the second cassette.

Polypropylene or the like is selected from the viewpoint of the bending durability of the hinge portion 3 as the synthetic resin constituting the main body bottom portion 1 and the lid bottom portions 2A, 2B.

As shown in FIG. 2, U-shaped grooves 10 are formed in the bottom portions 2A and 2B of the lid body, respectively.

The cross section of this groove 10 is as shown in FIG.
A locking hole 11 is formed in the side surface of 0.

On the other hand, the lid portions 20A and 20B having a substantially U-shaped cross section include a lid flat portion 21, lid side portions 22 on both sides thereof, and a lid bent at a right angle inward from the tip of the lid side portion 22. The body folding portion 23 is made of a transparent synthetic resin such as styrene, and one end is connected to the groove 1 of the lid bottom portion 2A, 2B.
This is a fitting portion 24 that can be fitted to the 0.

A locking convex portion 25 that engages with the locking hole 11 is integrally formed in the fitting portion 24 .

These lid portions 20A and 20B are connected to the fitting portion 24.
are fitted into the grooves 10 of the lid bottoms 2A, 2B, and the locking protrusions 25 are fitted into the locking holes 11, so that they are integrally attached to the lid bottoms 2A, 2B, respectively.

In addition, when fixing firmly, the fitting part 24 should have a plurality of locking protrusions 25 or have a large area for locking and fixing.

Further, an anti-slip uneven portion 26 is formed on the outer surface of the lid body side portion 22 to prevent slipping during opening and closing.

In the configuration of the above embodiment, the lid body portion 20A.

20B is rotatable with respect to the bottom part 1 of the main body along with the lid bottom parts 2A and 2B via the hinge part 3, so open (stand up) the lid parts 20A and 20B and move in the direction shown by the arrow in FIG. Insert the cassette 7 as shown, and while holding the cassette 7 with the lid parts 2OA and 20B, move the lid parts 20A and 20B in the direction of arrow B.
When the cassette 7 is rotated and closed as shown in FIG.

As a result, the cassette can be stored or carried without loosening the magnetic tape inside the cassette.

The outer shape of this cassette storage case is a thin and elongated rectangular parallelepiped that resembles a pencil case, making it convenient to carry.

FIG. 4 shows another embodiment of the invention.

In this figure, there is a notch 30 in the middle of the main body side parts 4A and 4B, and a bending groove 31 on the back surface of the main body bottom part 1.
are formed, respectively, so that the bottom surface portion 1 of the main body is slightly bent as shown by arrow C at the intermediate portion.

This is to make it easier to open only one of the lids 20A and 20B.

Note that the other configurations are the same as in the previous embodiment.

As explained above, according to the present invention, two cassettes can be stored compactly and the shape is convenient for carrying.
A cassette storage case that is easy to manufacture can be obtained.
