However, such a storage case has the following problems. First, the side ribs 54 and 55 are formed, but the side ribs 54 and 55 are projected relatively long upward from the bottom surface portion 51. Considering the thickness of the bottom surface portion 51, the side ribs 54 and 55 are formed. Since only the portion 55 is extremely thick, when the storage case is resin-molded, as shown by H in FIG. 9 which is a sectional view taken along the line CC of FIG. A sink is likely to occur at a position on the back side of the side ribs 54, 55. And there is a problem that the appearance of the storage case is damaged by the sink mark.

Further, as described above, the front rib 53,
The space surrounded by the side ribs 54, 55 and the back wall portion 52 is referred to as a cassette storage space S.
The side ribs 54 and 55 are spaced apart from each other so that the DAT cassette CT can be easily taken in and out.
It is slightly wider than the lateral size of T, and as shown by W in FIG. 10, the DAT cassette CT and the side ribs 54,
A gap is formed between 55.

As a result, the DAT cassette CT is not pressed into contact with the side ribs 54, 55 and can be easily taken in and out. However, in the storage state shown in FIG. 8B, the DAT cassette CT is loose in the storage case. There is also a problem in that the storage state is not suitable and the storage state is not suitable.

[0008]

In view of such problems, the present invention suppresses the loss of aesthetics due to sink marks, and
It is an object of the present invention to provide a cassette storage case that prevents rattling of a stored cassette and that does not hinder loading and unloading.

For this reason, in the cassette housing case in which the side ribs are integrally projected upward from the vicinity of both sides of the bottom plate portion and the space between the both side ribs serves as the cassette housing portion, the bottom plate portion has a back side of the side rib. The groove is formed at the position on the bottom surface side. Also, on the side ribs,
The lower position projects toward the cassette storage portion side from the upper position to form a thick portion.

[0010]

[Function] If a groove is formed at a position on the bottom surface side, which is the back side of the side rib where the sink mark is likely to occur, the sink mark hardly makes the appearance noticeable by the groove part, and the groove portion is used as a guide for the label sticking position. Can be used. In addition, if the side rib is formed with a portion where the lower position projects toward the cassette housing portion side rather than the upper position and becomes thick, the position fixing action at the time of housing for the cassette housing the thick portion is formed. With the eggplant, the strength of the side ribs also improves.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS. 1 to 3 and a second embodiment will be described with reference to FIGS.

FIG. 1 is a perspective view of the storage case according to the first embodiment in an open state. This storage case is basically the same in shape as the storage case shown in FIG. 8, and is integrally formed of resin so that the lower lid 10 and the upper lid 20 are connected by a hinge 30.

The lower lid 10 has a bottom surface portion 11 and a back wall portion 12.
In addition, front ribs 13 and side ribs 14 and 15 project upward from the bottom surface portion 11. The space S surrounded by the front ribs 13, the side ribs 14 and 15, and the back wall portion 12 serves as a cassette storage space. The upper lid 20 has a front wall portion 22 around the upper surface portion 21,
The side wall portions 23 and 24 are formed.

Then, the side ribs 14 and 15 of the lower lid 10
Engagement holes 14a and 15a are formed in the upper lid 20.
The side walls 23, 24 of the protrusions 23a, 2
4a is formed.

The state in which the DAT cassette CT is placed in the cassette storage space S of the lower lid 10 of the storage case and the upper lid 20 is closed is almost the same as that shown in FIG. When 20 is closed, the front wall portion 22 and the side wall portions 23 and 24 are located outside the front ribs 13 and the side ribs 14 and 15, and in this state, the engagement hole 14a and the protrusion 23a, and the engagement hole 15a and the protrusion 23a. The upper lid 10 and the lower lid 20 are locked to each other by the engagement of 24a, and the state in which the DAT cassette CT is housed is maintained.

Here, 16 is a groove provided on the bottom surface side of the bottom portion 11, and as can be seen from FIG. 2 which is a sectional view taken along line AA of FIG. 1, this groove 16 is a side rib 14 (and 15).
Is formed at a position on the back side of the. Further, it is provided not only on the back side positions of the side ribs 14 and 15 but also along the back wall portion 12 and in the vicinity thereof, and is a U-shaped groove as seen from FIG. 3 viewed from the bottom surface side of the bottom surface portion 11.

Side ribs 14 and 15 on the bottom surface portion 11
Although sink marks are likely to occur at the position on the back side of the sink mark, even if sink marks are generated, in this embodiment, the sink marks are generated in the groove 16, and in practice, the sink marks are almost conspicuous in appearance. Since it disappears, there is no aesthetic loss.

Further, since the groove 16 is formed as shown in FIG. 3, it is suitable when the portion surrounded by the groove 16 is used as the label sticking area L. In other words, the groove 16 serves as a guide for the label sticking position for the user so that the label sticking can be performed in a good appearance.

FIG. 4 is a perspective view of the storage case of the second embodiment. The same parts as those of the first embodiment are designated by the same reference numerals and the description thereof will be omitted. In this example, FIG.
As can be seen from FIG. 5 which is a sectional view taken along line B, the side rib 1
4 and 15, a thick portion 14 whose lower position projects toward the cassette storage portion side more than the upper position and becomes thicker.
b and 15b are provided.

The interval between the thick portions 14b and 15b is substantially the same as the lateral size of the DAT cassette CT. Therefore, when the DAT cassette CT is arranged in the cassette storage space S, as shown in FIG. The thick-walled portions 14b and 15b are in a state of lightly pressing both side portions of the DAT cassette CT.

That is, the DAT cassette CT stored in the storage case of this embodiment has a thick wall portion 14 inside the storage case.
The position is fixed by b and 15b, so DA when stored
The looseness of the T cassette CT is eliminated.

Further, the thick portions 14b and 15b of the side ribs 14 and 15 are only the root portions,
Since the portions above the thick portions 14b and 15b are not made thick, there is a gap shown as W in FIG.
Since the AT cassette CT is not so firmly fixed, it does not become difficult to take it in and out.

The thick portions 14 are formed on the side ribs 14 and 15.
The side ribs 14 and 1 are provided by providing b and 15b.
There is also an advantage that the strength of No. 5 is improved. Of course, also in this embodiment, since the groove 16 is formed on the back side of the side ribs 14 and 15, even if a sink mark occurs, the appearance is not deteriorated. Incidentally, as a modification of this embodiment, an example in which the groove 16 is not provided as in FIG. 7 can be considered.

Although the first and second embodiments of the present invention have been described above, various modified embodiments are conceivable as the present invention. For example, the groove 16 is the front rib 13
It may be provided at the position on the back side of the front rib 13 or may be provided on the back side of the front rib 13 if there is a possibility that a sink may occur at this position as well due to the height of the front rib 13 and the thickness of the bottom surface portion 11. Is preferred. Further, it may be considered that the groove 16 is not provided in the portion along the back wall portion 12.

Further, although the groove 16 is used as a guide for the label sticking area, in addition to this, a rail-like projection is provided on the upper surface portion 21 of the upper lid 20 at the same position as the groove 16 on the bottom surface portion 11. For example, when a plurality of storage cases are stacked, the grooves and the protrusions may be fitted to each other so that the positioning at the time of stacking can be performed.

Further, the thick portions 14b and 15b may not be continuously provided along the side rib main body portion as shown in FIG. 4, but may be formed separately in partial portions.

Although the case of storing the DAT cassette has been described, it goes without saying that the present invention can be applied as a cassette storing case for all cassettes such as tape cassettes and disk cassettes.

[0028]

As described above, in the cassette storage case of the present invention, by forming the groove portion at the position on the bottom surface side which is the back side of the side rib where the sink mark is likely to occur, even if the sink mark occurs, the groove portion is formed. There is an effect that the sink marks are hardly noticeable on the appearance and the aesthetic loss can be almost eliminated. Further, the groove portion can be effectively used as a guide for a label sticking position.

Further, if the side rib is formed with a portion where the lower position projects toward the cassette storage portion side more than the upper position and becomes thick, the thick portion is stored at the position when stored in the cassette. This has the effect of fixing the cassette, eliminating the rattling of the cassette that is stored with a structure that does not hinder the loading and unloading of the cassette, and also improves the strength of the side ribs.
