Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a cassette storage case, particularly a large tape cassette storage case having a plurality of through holes and a built-in reel rotation prevention mechanism.

Conventionally, as a case for storing large-sized tape cassettes such as video tape cassettes, a case 3 is used in which appropriate information 2 is silk-printed on a paper box 1, as shown in FIG. 1, in order to reduce costs.

However, paper products like this require more time and effort to process than resin products, which not only increases production costs, but also causes wrinkles and fading when stored for long periods of time. Another drawback is that it is weak.

Therefore, it is conceivable to make the case with the above structure made of resin, but in that case, molding would be difficult, and since the case structure is as described above, there is no means for locking the cassette inserted into the case. Another drawback is that the cassette easily falls out of the case when the button is pressed and the case is turned upside down during transportation.

In order to improve the drawbacks of the conventional cassette storage case, the present invention is characterized in that a cassette fixing boss is provided on the bottom plate made of resin such as polyethylene to be inserted and locked into the through hole of the cassette.

The present invention will be described below with reference to embodiments shown in the drawings.
In FIG. 2, reference numeral 4 designates an embodiment of the case according to the present invention, which is molded from a resin such as polyethylene, and is used for storing and fixing a large cassette 5 having a built-in reel rotation prevention mechanism.

Of course, it can also be used as a Phillips-type compact cassette storage case by adjusting the dimensions to a predetermined size.

The case 4 consists of a bottom plate 6 and a side plate T, and the bottom plate 6 is provided with cassette fixing bosses 9 and 10 that are inserted and locked into a through hole of the cassette 5, for example, a reference hole 8° 8', and a side plate 7. are provided with lips 11 and 12 similar to the cassette positioning lips provided in the Philips type compact cassette storage case.

The bosses 9 and 10 are formed with slots 13 as shown in FIG. 3, for example, and when inserted into the reference holes, they are elastically engaged and the cassette 5 is stably fixed and held.

In conventional handy cases, etc., the hub part 14 is used to lock the case, but in the case of large cassettes, the shape of the reel makes it difficult to use elasticity to secure the case as in the present invention. be.

On the other hand, the reference hole has good dimensional accuracy, and by utilizing this to elastically lock the cassette to the boss, the cassette can be stably fixed, which is a unique idea of the present invention.

Note that the bottom plate 6 may preferably be provided with a notch 15 in order to facilitate the insertion and removal of the cassette 5, for example.

Alternatively, as shown in FIG. 4, left and right side plates 16 and 17 may be provided on the bottom plate 6, and a lid 18 may be placed over the rear side plate 1 by means of a hinge 19.

In this case, a boss 2 that fits into the bosses 9 and 10 on the lid 18
By providing 0°21, the effect of fixing and holding the cassette becomes even more reliable.

Further, if the case of the present invention is placed in a bag made of polyethylene or cellophane paper and sealed, it is effective in terms of dustproofing effect.

As explained above, according to the present invention, it is possible to provide a cassette storage case that is inexpensive, prevents deterioration such as color change due to direct sunlight, and has no problems in terms of strength.
