A pair of rotation prevention mechanisms 33 and 34 are provided at the bottom of the case body 2 to prevent rotation of the tape reel of the tape cassette that is fitted into the hub hole of the tape reel of the tape cassette to be stored. .

According to the storage case configured as described above, it is possible to accurately position and close the lid without causing a relative shift between the case body 2 and the lid 4, and the lid can be closed without causing any relative displacement between the case body 2 and the lid 4. Since the case itself is not deformed by external force, the stored items can be reliably protected.

Further, since the case body 2 and the lid body 4, excluding the rotation stopper mechanisms 33 and 34, can be integrally formed by molding of synthetic resin, manufacturing is extremely easy.

However, in order to store the tape cassette while reliably protecting it from external forces and other forces, it is necessary to install the left and right walls 7 and 8 surrounding the tape cassette in the case body 2, as well as the front and A rear side wall of 6°9 is required.

The side of the lid 4 that is continuous with the case body 2 and is closed by fitting into the case body 2 must be left open on the side facing the rear wall 9 of the case body 2. .

Therefore, the left and right side walls 17, 18 of the lid body 4 on the rear wall 9 side, that is, on the side where the rear plate 3 is connected, must be configured as open ends 29, 30.

In order to store a tape cassette having a predetermined height, the left and right walls 7, 8, etc. of the case body 2 must also have corresponding heights, and the outside of the E and right walls 7, 8 must also have a corresponding height. The left and right side walls 17, 18 of the upper lid 4, which fit tightly on both sides, must also be formed with a predetermined height.

However, if the left and right side walls 17, 18, which have a predetermined height and have an upright shape with one end serving as the open end portions 29, 30, are molded together with the lid body 4 etc. from synthetic resin, the above-mentioned open ends The vicinity of the end portions 29° and 30 are inclined toward the inner side of the lid body 4, that is, the direction in which they face each other, as shown in FIG.

The open ends 29.3 of the left and right side walls 17.18 as described above.
0 is tilted, when the lid is closed, the bent pieces 31 and 32 provided on the left and right side walls 17 and 1B do not come into close contact with the back plate 3 that connects the case body 2 and the lid 4, and the third As shown in the figure, a gap 35 is created.

This gap 35 is significantly enlarged at the bottom 5 of the case body 2.

Therefore, the bending pieces 31.32 provided to obtain the mechanical strength of the hinge portion 22.23 no longer function, and the reliability of the hinge portion 23 is impaired.

Furthermore, when the lid is closed, the entire storage case 1 is distorted, and the appearance of the storage case 1 is also deteriorated.

Therefore, the present invention effectively prevents the above-mentioned gap that occurs when the lid is closed, and allows the lid to fit tightly into the case body when the lid is fitted into the case body. A protrusion for correcting the fitting position of the lid body is provided on the outer surface of the proximal side of the left and right side walls of the case body where the open end facing the front side wall of the left and right side walls overlaps. It is.

Hereinafter, embodiments for improving the above-mentioned points will be described with reference to the drawings.

As shown in FIG. 4, the open end portions 29.30 of the left and right side walls 17.18 of the lid body 4, which are inclined inward during molding, overlap when the lid is closed. A reinforcing wall 28, 28 is formed continuously on the base end side of the left and right side walls 7, 8 on the side of the hinge portion 22, and forms a part of the left and right side walls 7, 8. Protrusions 36 and 36 for correcting the fitting position of the lid are provided on the outer surface of each of the lids.

As shown in FIG. 4, the protruding portions 36 are connected in the height direction at the side end of the reinforcing wall 28 on the hinge portion 22 side.

As shown in FIGS. 5A and 5B, the protrusion 36 is formed into a triangular pyramid shape whose tip tapers upward from the bottom 5 side.

That is, the protruding portion 36 is formed to have a slope whose protruding amount decreases as it goes in the height direction of the left and right side walls 7 and 8.

The reason why the tip of the protrusion 36 is tapered in this way is to ensure that the tips of the left and right side walls 17° and 18 of the upper lid 4, which have the largest inclination width, overlap smoothly. .

Further, the protruding portion 36 may be formed into a semi-conical shape with a tapered tip as shown in FIGS. 6A and 6B.

The protrusions 36, 36 formed as described above are attached to the reinforcing wall 28.
28, the left side of the lid body 4 tilted inwardly.
The open ends 29, 30 of the right side wall 17, 18 are gradually corrected outward by closing the lid, and the above-mentioned inclination is eliminated.

That is, when the upper cover 4 is fitted to the case body 2, as shown in FIG. The gradually increasing tip rides on the bottom side of the protrusion 36 whose height gradually increases.

Accordingly, the inclination of the open end portion 29 is corrected,
The lid body 4 fits into the case body 2.

As shown in FIG. 8, the bent pieces 32 provided on the left and right side walls 18 of the lid body 4 are in close contact with the back plate 3, and the lid is closed without any gaps.

Note that the protruding portion 36 constituting the present invention is not limited to the above-mentioned example, and may have any shape as long as the tip thereof is tapered.
Several strips may be provided depending on the slope of No. 8.

As described above, according to the present invention, it is possible to effectively prevent the occurrence of a gap when the lid is closed, and to ensure a tight fit between the lid and the case body.

This ensures protection of the hinge portion of the storage case and improves the durability of the storage case itself.
