Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape cassette storage case for storing a tape cassette in a temporarily fixed state.

[0002]

2. Description of the Related Art A conventional tape cassette storage case is shown in FIG.
Is shown in. In FIG. 3, the tape cassette storage case 2 is composed of a bottom surface portion 8, an upper surface portion 9 and a connecting portion 10 for connecting them, and each connecting portion is constituted by a hinge 11. A side wall portion 12 is provided upright on the periphery of the bottom surface portion 8, and the tape cassette 1 is housed in a space surrounded by the side wall portion 12. Further, a pair of reel centering ribs 14 are erected on the bottom surface portion 8, and the pair of reel centering ribs 14 are inserted into the pair of reel holes 6 of the tape cassette 1 when the tape cassette is stored. Further, a temporary fixing rib 15 is provided upright on the bottom surface portion 8, and the temporary fixing rib 15 is inserted into the temporary fixing hole 7 of the tape cassette 1 when the tape cassette is stored. As shown in FIG. 4A, the temporary fixing rib 15 includes a pair of semi-arcuate elastic rib pieces 15a, 1a.
5b, each of the elastic rib pieces 15a, 15b is provided with a projection 16 at the tip end side thereof.

In the above structure, when the tape cassette is stored, the pair of elastic rib pieces 15a and 15b are flexibly deformed in a direction toward each other as shown in FIG. The cassette 1 is temporarily fixed.

[0004]

However, in the above-mentioned conventional configuration, when a shock is applied in the direction of arrow A in FIG. 4 (b) when the tape cassette is stored, the one elastic rib piece 15a is caused by the shock. 4 (b), it is largely bent as shown by an imaginary line, and the elastic deformation causes one elastic rib piece 15a to be bent at its root portion. Also, FIG.
When an impact is applied in the direction of arrow B in (b), the other elastic rib piece 15b is broken for the same reason as above. When the elastic rib pieces 15a and 15b are thus folded, not only the tape cassette storage case 2 becomes a defective product, but also when the tape cassette 1 is lowered with the upper surface portion 9 opened, the tape cassette 1 becomes the tape cassette storage case. Accidents such as falling off from the sheet 2 or one of the folded elastic rib pieces 15a possibly entering the tape cassette 1 occur.

Therefore, an object of the present invention is to provide a tape cassette storage case in which the elastic rib pieces do not break even if an impact is applied by being dropped or the like.

[0006]

A tape cassette storage case according to the present invention for achieving the above object has a temporary fixing rib formed of a pair of elastic rib pieces on the bottom surface thereof, and the temporary fixing rib is provided in the tape cassette. In the tape cassette storage case for temporarily fixing the tape cassette by flexurally deforming the pair of elastic rib pieces in the state of being inserted in the temporary fixing hole, the space between the pair of elastic rib pieces is When one of the elastic rib pieces is flexibly deformed until it comes into contact with the other elastic rib piece, the maximum elastic deformation point of the one elastic rib piece is set to a dimension that does not exceed the elastic limit. Is.

[0007]

When the tape cassette is stored, an impact is applied by dropping or the like, and if the impact direction is a direction in which one elastic rib piece approaches the other elastic rib piece, the impact causes one elastic rib piece to move to the other. The elastic rib pieces may be flexibly deformed until they come into contact with each other, but the distance between the pair of elastic rib pieces is such that the maximum elastic deformation point of one elastic rib piece does not exceed the elastic limit at the maximum deflection. Therefore, one elastic rib piece does not break.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show an embodiment of the present invention. FIG. 2 shows a perspective view of the tape cassette 1 and the tape cassette storage case 2 that stores the tape cassette 1. Figure 2
In the tape cassette 1, a case 3 has a pair of reels 4 rotatably housed therein, and a tape (not shown) is wound around the pair of reels 4. A lid 5 is rotatably provided on the front surface of the case 3, and the tape is covered and exposed by the rotation of the lid 5. Further, a pair of reel holes 6 for rotating the pair of reels 4 is formed on the lower surface of the case 3.
And a temporary fixing hole 7 is formed in the middle of the pair of reel holes 6 and slightly on the front side. The temporary fixing hole 7 is a hole into which the tape end detection sensor is inserted when the drive device is mounted.

The tape cassette storage case 2 is made of a hard synthetic resin, and comprises a bottom surface portion 8 and an upper surface portion 9 and a connecting portion 10 for connecting them, and between the bottom surface portion 8 and the connecting portion 10 and between the upper surface portions 9. The connecting portions 10 are connected to each other via hinges 11. Side wall portions 12 are provided upright on the peripheral edge of the bottom surface portion 8 and the peripheral edge of the upper surface portion 9, respectively.
When covered, both side wall portions 12 are arranged in an overlapped state.

A space surrounded by the side wall portion 12 of the bottom surface portion 8 is configured as a cassette storage chamber 13, and a pair of reel centering ribs 14 and a temporary fixing rib 15 are provided upright on the cassette storage chamber 13 side. There is. The pair of reel centering ribs 14 and the temporary fixing ribs 15 are integrally formed with the bottom surface portion 8 and arranged at corresponding positions of the pair of reel holes 6 and the temporary fixing hole 7 of the tape cassette 1 in the housed state. Has been done.

The temporary fixing rib 15 is composed of a pair of elastic rib pieces 15a and 15b which are arranged at positions opposed to each other, and the pair of elastic rib pieces 15a and 15b each have a substantially semi-arcuate shape when viewed from above. are doing. Each elastic rib piece 1
Projections 16 are provided outward at the tips of 5a and 15b, respectively. Also, a pair of elastic rib pieces 15a, 1
As shown in FIGS. 1 (a) and 1 (b), the distance D between the 5b is one when one of the elastic rib pieces 15a or 15b is flexibly deformed until it contacts the other elastic rib piece 15b or 15a. The root of the elastic rib piece 15a or 15b, which is the maximum elastic deformation point, is set to a dimension that does not exceed the elastic limit. That is, this dimension is equal to the elastic rib piece 15
It is appropriately determined according to the material, shape, thickness, height, etc. of a and 15b.

In the above structure, when the tape cassette 1 is inserted into the cassette housing chamber 13 of the bottom surface 8 with the upper surface 9 opened, the pair of reel centering ribs 16 are inserted into the pair of reel holes 6 of the tape cassette 1. At the same time, the temporary fixing rib 15 is inserted into the temporary fixing hole 7 of the tape cassette 1. The pair of reel centering ribs 16 are inserted into the pair of reel holes 6 with a sufficient gap. As shown in FIG. 1 (b), the temporary fixing rib 15 is a pair of elastic rib pieces 1.
The 5a and 15b are flexibly deformed in a direction in which they approach each other, so that they are inserted into the temporary fixing holes 7, and the elastic restoring forces act on the tape cassette 1 to temporarily fix the tape cassette 1.

Here, for example, when the tape cassette housing case 2 housing the tape cassette 1 is dropped and a shock is applied in the direction of arrow A in FIG. 1B, this shock causes the elasticity of one side via the tape cassette 1. It is transmitted to the rib piece 15a. Then, one elastic rib piece 15a is flexibly deformed until it comes into contact with the other elastic rib piece 15b in the maximum range, as shown by an imaginary line in FIG. 1 (b). However, even if the elastic deformation is maximum, the deformation of the root of the elastic rib piece 15a, which is the maximum elastic deformation point, does not exceed the elastic limit, so that the elastic rib piece 15a does not break. Further, even if an impact is applied in the direction of the arrow B in FIG. 1B for some reason, the other elastic rib piece 15 is for the same reason as above.
b does not break.

In this embodiment, each elastic rib piece 15a,
Although 15b has a substantially semi-circular shape, it may have any shape as long as it can be flexurally deformed in a direction toward each other.

[0015]

As described above, according to the present invention, in the tape cassette storage case for temporarily fixing the tape cassette by bending and deforming the pair of elastic rib pieces inserted into the temporary fixing holes of the tape cassette, Since the space between the elastic rib pieces is narrowed to a predetermined value or less, the elastic rib pieces do not break even when an impact is applied by dropping or the like, and there is an effect that an accident due to the breaking of the elastic rib pieces can be prevented.
