Description

[Detailed Description of the Invention] The present invention relates to a cassette storage case, and is designed to securely attach index paper within the case.

First, a conventional cassette storage case will be explained with reference to FIG. A front plate 5 and side plates 6 and 7 that are continuous with the front plate 5 are integrally formed, and cassette regulation plates 8 and 9 are integrally formed inside the side plates 6 and 7, and the regulation plates A rear plate 10 continuous with 8°9 is integrally formed.

The upper case 1 and the bottom case 2 are the side plate 3 of the upper case 1,
4 and the regulating plates 8, 9 of the bottom case 2 are the shafts 11a, 11
They are rotatably connected at b, and the upper case 1 can be opened and closed with respect to the bottom case 2.

In this case, the cutout steps 3a of the side plates 3 and 4 of the upper case 1
, 4a are configured to contact the step portions 6a, 7a of the side plates 6, 7 of the bottom case 2 in a planar manner so as to form a box as a whole.

Denoted at 12 and 13 are cassette hub rotation prevention members integrally formed on the upper surface of the bottom case 2, and the cassette is housed in the bottom case 2 with the pair of hubs engaged with the rotation prevention members 12 and 13. , the upper case 1 is closed and stored.

Here, an index paper 14 for recording, for example, titles of recorded tapes, etc., is also housed in the case.

This inch paper 14 is U-shaped and has two holes 15 and 16 in its center.
The anti-rotation members 12 and 13 are fitted and placed on the inner surface of the bottom case 2, and both ends 14a and 14b are joined to the inner surfaces of the front plate 5 and the rear plate 1D, and are inserted through the transparent bottom case 2. The index written on the index paper 14 can be read.

However, in this conventional case, index paper 1
4 is simply joined to the inner surfaces of the front plate 5 and rear plate 10 at both ends 14a and 14b and placed on the bottom case 2, so the upper case 1 must be opened to store or take out the cassette. There is a drawback that the index paper 14 has the disadvantage that it floats up or falls off.
Since the holes 15 and 16 into which the number 3 is inserted are provided, there is a drawback that there is little space for writing the index.

The present invention eliminates these conventional drawbacks, and one embodiment thereof will be described below with reference to FIGS. 2 to 5.

In FIGS. 2 to 5, the same components as those in the conventional one shown in FIG. Leading edge wall 17
, 1B are provided, and a rear plate 19 is integrally formed at the rear end, and protrusions 20a and 20b are formed on the upper inner surfaces of the side plates 3 and 4. The protrusions 21a and 21b are integrally formed.

The index paper 14 of this embodiment does not have a hole through which a rotation preventing member is passed, and the end portion 14a is folded to form an L-shape.

As shown in FIG. 5, this index paper 14 is inserted from the end 14a between the inner surface of the upper case 1 and the protrusions 20a, 20b with the upper case 1 open, and the index paper 14
The end portion 14 a is positioned along the inner surface of the rear plate 19 by utilizing the fact that the end portion 4 itself elastically returns to its original L-shape.

At this time, the other end of the index paper 14 is connected to the front edge wall 17.
．． Go inside 1B.

With this configuration, the index paper 14 can be seen through the transparent upper case 1 and the index paper 1 can be viewed through the transparent upper case 1.
Not only can you see the index contents written in the index paper 14, but also the index paper 14 has protrusions 20a,
20 b prevents its falling off, and the leading edge wall 17
．． Since removal is prevented by 18, even if the upper case 1 is opened when storing or removing a cassette, or even if the upper case 1 is closed without storing the cassette, there will be no displacement, and the upper case 1 will always be opened and closed integrally with the upper case 1. It is something that

When the upper case 1 is closed, the protrusions 21 a and 21 b of the bottom case 2 face the end 14 a of the index paper 14 with a slight interval, as shown in FIG.
Therefore, there is no possibility that the end portion 14a goes inward.

In the above embodiments, the front edge walls for preventing the index paper from being pulled out are provided at the left and right ends of the front edge of the upper case, but these may be provided over the entire length of the front edge of the upper case.
Various modifications are possible, such as providing it only in the central portion of the front end.

As described above, the present invention provides a front edge wall at the front end of the upper case, a rear plate at the rear of the upper case, a protrusion on the inner surface of the side plate of the upper case, and a connection between the inner side of the front edge wall and the protrusion. By positioning an L-shaped index paper between the inner surfaces of the upper case and aligning the L-shaped bent end of the index paper with the inner surface of the rear plate, the index paper can be dropped off. It is possible to hold the paper along the inner surface of the upper case and the inner surface of the rear plate without any problems, so that the inch paper will not float up or fall when the upper case is opened and closed or when the cassette is stored or removed. Moreover, since the index paper is joined to the upper case, there is no hole for inserting the rotation preventing member, and therefore the space for writing the index is large, and its practicality is great.
