DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an index card and a label sheet inserted into a cassette storage case.

[0002]

2. Description of the Related Art Generally, a tape cassette is stored in a dedicated cassette storage case as shown in FIG. That is, in FIG. 1, reference numeral 1 denotes a cassette storage case formed of a transparent resin, and 2 denotes a compact audio cassette (hereinafter referred to as a tape cassette) stored in the cassette storage case 1. On both upper and lower surfaces, trapezoidal bulging portions 3 forming front opening portions (magnetic tape exposed portions into which a magnetic head, a pinch roller and the like are inserted) are formed (see FIG. 7).

[0003] An index card (card for writing music or the like) 4 is usually inserted into the cassette storage case 1 while being sandwiched between the inner surface of the case and the tape cassette 2, and a label sheet (tape) is further inserted inside the index card. The label sheet 5 to be attached to the cassette is inserted.

In recent years, in this type of cassette storage case 1, as shown in the drawing, a concave portion 1a in which the trapezoidal bulging portion 3 of the tape cassette 2 is formed is formed on the inner surface of the case, thereby reducing the thickness of the entire cassette storage case. A thin case designed to be thin has been proposed (for example, Japanese Utility Model Laid-Open No. 60-163279).

[0005]

However, even if the recess 1a for accommodating the trapezoidal bulge 3 of the tape cassette 2 is provided on the inner surface of the cassette storage case 1 as described above, the index card 4 and the label sheet 5 may cause obstacles. Become concave 1
The trapezoidal bulging part 3 cannot be accommodated in a.

Here, it is not impossible to forcibly fit the trapezoidal bulging portion 3 in the concave portion 1a, but in this case, the index card 4 and the label sheet 5 are forcibly deformed into a shape along the concave portion 1a, so that wrinkles are formed. Will occur. The index card 4 only needs to have a hole in a portion corresponding to the trapezoidal bulging portion 3, but it has a poor appearance when viewed from the outside of the case.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is to accommodate a tape cassette having a trapezoidal bulging portion forming a front opening on both upper and lower surfaces of a cassette housing. An index card inserted into a cassette storage case having a concave portion in which the trapezoidal bulging portion of the tape cassette fits in the inner surface, wherein a required cut is provided in a portion corresponding to the trapezoidal bulging portion of the tape cassette. is there.

Also, in a label sheet inserted into a cassette storage case for storing a tape cassette having a trapezoidal bulging portion forming a front opening on both upper and lower surfaces of the cassette housing, the tape cassette has a trapezoidal expansion. A portion corresponding to the protrusion is cut out in a concave shape.

[0009]

With the above arrangement, when the tape cassette is stored in the cassette storage case, the trapezoidal bulging portion can be smoothly housed in the concave portion without any obstacle to the index card and the label sheet.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a first embodiment of the present invention; FIG.

FIG. 1 is a cross-sectional view of a main part of a thin cassette storage case 1 showing an embodiment. In this case, first, a cutting process is performed on a portion of an index card 4 corresponding to a trapezoidal bulging portion 3 of a tape cassette 2. It has been given.

That is, as shown in FIG. 2, the index card 4 is provided with streaky cuts 4a corresponding to three sides of the left and right side edges 3a, 3b and the front side edge 3c of the trapezoidal bulging portion 3 of the tape cassette 2. Is formed. In addition, trapezoidal bulging part 3
A portion corresponding to the rear side edge 3d is a bent portion 4b.

With this configuration, when the tape cassette is stored in the cassette storage case 1, the index card 4 is formed so that the portion surrounded by the cut 4a is formed along the recess 1a on the inner surface of the case by the trapezoidal bulging portion 3. It is easily extruded and deformed, so that the trapezoidal bulging portion 3 can be smoothly recessed without the index card 4 becoming an obstacle.
a.

Since the index card 4 is easily deformed by the cuts 4a as described above, wrinkles and the like do not occur. Therefore, when viewed from the outside of the cassette storage case 1, there is only a slight streak due to the cut. It has almost the same appearance.

In addition, as shown in FIG. 3, the index card 4 is cut into portions corresponding to the three sides of the left and right side edges 3a, 3b and the rear side edge 3d of the trapezoidal bulging portion 3 of the tape cassette 2. 4a may be provided continuously, and a portion corresponding to the front side edge 3c of the trapezoidal bulging portion 3 may be a bent portion 4b.

On the other hand, in the label sheet 5 inserted into the cassette storage case 1 together with the index card 4, the portion corresponding to the trapezoidal bulging portion 3 of the tape cassette 2 is replaced with the trapezoidal bulging portion as shown in FIG. A notch 5a is formed in a concave shape following the reference numeral 3.

For this reason, when the tape cassette 2 is stored in the cassette storage case 1, the notch 5a serves as a relief for the trapezoidal bulging portion 3, so that the trapezoidal bulging portion 3 is smooth without the label sheet 5 becoming an obstacle. In the recess 1a.

Further, since the label sheet 5 has leg portions on both sides of the notch 5a, even if the label sheet 5 moves within the cassette storage case 1, the label sheet 5 is located below the trapezoidal bulging portion 3 of the tape cassette 2. Don't come.

Further, the label sheet 5 is not limited to the thin cassette storage case 1 having the concave portion 1a in which the trapezoidal bulging portion 3 of the tape cassette 2 is accommodated, but may be a general cassette storage case as shown in FIG. This is also effective in case 6.

That is, in the case of the general cassette storage case 6, the label sheet 5 is inserted so as to overlap the trapezoidal bulging portion 3 of the tape cassette 2 as shown in FIG. 5A. According to the label sheet 5 of the present embodiment, the notch 5a serves as a relief for the trapezoidal bulging portion 3 and the label sheet 5
Does not come under the trapezoidal bulging portion 3, so that the cassette storage case 6 has the thickness of the label sheet 5 as shown in FIG.
Can be formed thin.

[0021]

As described above, according to the index card of the present invention, in a cassette storage case having a recess for accommodating a trapezoidal bulge of a tape cassette, the index card does not hinder the storage of the tape cassette. Since the trapezoidal bulging portion can be smoothly housed in the concave portion, and the index card is not provided with a hole, the appearance which is almost the same as the conventional index card when viewed from the outside of the case can be obtained.

Further, according to the label sheet of the present invention, in a cassette storage case having a concave portion for accommodating the trapezoidal bulging portion of the tape cassette, the label sheet does not become an obstacle when the tape cassette is stored without trapping. This makes it possible to smoothly accommodate the portion in the concave portion, and also has the effect that the thickness can be reduced by the thickness of the label sheet even in a general cassette storage case.
