[0002]
[Prior art]
As shown in FIGS. 5 (a) and 5 (b), a conventional disk case of this kind is provided with a convex portion 103 at the center of a case body 102 as means for supporting the disk when the disk is accommodated in the disk case 101. , 104, the center hole of the disk is fitted into the projections 103, 104, and the disk is removed by pressing the projections 103, 104 when the disk is removed. Was.
However, in this case, if the convex portions 103 and 104 are pressed too hard, the inner peripheral portion of the disk is cracked, and in some cases, the data portion in which the information of the disk is stored cannot be read, and the data may be reproduced. There is a problem that the disc may not be able to be read.
[0003]
In particular, in the disk case shown in FIG. 5A, there was a problem that the fixed portion of the disk was often damaged and the reproduction surface of the disk was often damaged.

[Problems to be solved by the invention]
The present invention solves the above-mentioned conventional problems, and provides a disk case that can prevent the disk case from being damaged, prevent the center side of the disk and the reproducing surface from being damaged, and have a simple structure. It is intended to be.
[0008]
[Means for Solving the Problems]
SUMMARY OF THE INVENTION The present invention has been proposed to solve the above-mentioned problems. The invention according to claim 1 is provided by folding a case body accommodating a disk, which is connected to one side of the case body. A case cover that covers the case body, a substantially semicircular ridge in a plan view is provided at a position near an outer end of a portion of the case body that accommodates the disk, and the bulge of the disk is formed on the ridge. In order to fit one side edge of the shape, an arc-shaped groove is formed so as to bite in. The arc-shaped groove is provided at a position slightly above the surface of the case body and slightly lifts the disk. Arc shape of the disc, wherein the case lid is configured to hold the case body, and the one side edge of the arc shape is fitted into the arc groove when the case body is covered. A locking boss portion for locking the other side edge so as not to come out is provided, and a distal end surface of the locking boss portion is pressed so as not to slip out of the other side edge of the disc and pushed toward the center. It is formed on a downward tapered surface from the inside to the outside with the case lid covered.
[0009]
In the invention described in claim 2, both ends of the substantially semicircular raised portion in plan view provided on the case main body are formed in a curved state while being slightly biased toward the center .
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of a disk case according to the present invention will be described with reference to the drawings.
FIG. 1 is a plan view of a disc case according to an embodiment of the present invention with a case cover opened, FIG. 2 is a partial perspective view of a main part for fitting a peripheral edge of the disc, and FIG. 3 is provided on a case cover of the disc case. FIG. 10 is a partially enlarged cross-sectional view showing a state in which the disc is pressed by the tapered surface of the locking boss portion.
[0011]
As shown in FIG. 1, the disk case of the present embodiment includes a case main body 1 that accommodates a disk D, and a case lid 2 that is connected to one side of the case main body 1 and is folded to cover the case main body 1. And a substantially semicircular raised portion 3 in a plan view is provided near the outer end of a portion of the case body 1 for accommodating the disk D, and the raised portion 3 has one side edge of the arc shape of the disk D. An arc-shaped groove 4 (see FIG. 2) having a bite shape is formed to fit the portion d1.
On the other hand, the case cover 2 is provided with a locking boss portion 5 for locking the other side edge d2 of the disk D so as not to come out when the case body 1 is covered.
[0012]
Further, as shown in FIG. 3, the distal end surface of the locking boss portion 5 provided on the case lid 2 is covered with the case lid 2 so as to hold the disk D so as not to come out and push it toward the center. The tapered surface 5a is formed downward from the inside to the outside.
The arc groove 4 formed in the raised portion 3 provided in the case main body 1 is provided at a position slightly above the surface of the case main body 1 as shown in FIG. It is configured to be held in a state.
Then, after the disk D is fitted into the arc groove 4 of the raised portion 3 of the case main body 1 at one side edge d1, the case main body 1 is covered with the case lid 2, and the locking boss portion 5 of the disk D The other side edge d2 is locked, and the disk D is accommodated in a state fixed in the disk case.
[0013]
Therefore, according to the disk case of the present embodiment, it is possible to prevent the disk case from being damaged, and to prevent the center side of the disk D and the reproduction surface from being damaged.
Moreover, the structure is simple, and the entire disk case can be easily manufactured by integral molding of a synthetic resin, and can be provided at a low cost.
Further, the other side edge d2 of the disk D can be pressed by the tapered surface 5a at the tip end surface of the locking boss portion 5 of the case lid 2 so as to press the disk toward the center, so that the disk D is surely prevented from falling out. It can be accommodated in a fixed state.
Further, since the disk D can be held in a slightly floating state, there is an advantage that the recording surface on the back side of the disk D is not damaged.
[0014]
FIG. 4 is a plan view showing a disk case according to another embodiment, with a case lid opened.
As shown in FIG. 4, the disk case according to this alternative embodiment has a state in which both end portions 3a and 3b of a substantially semicircular raised portion 3 provided in the case main body 1 are slightly biased toward the center. It is curved.
Thereby, when the disk D is fitted into the arc groove 4 of the raised portion 3, the upper and lower edges of the disk D are pressed down by the urging forces of both edges 3a and 3b of the raised portion 3 in the drawing. This has the advantage that the disk D can be held firmly.
[0015]
【The invention's effect】
As described above , according to the first aspect of the invention , it is possible to prevent the disc case from being damaged, and to prevent the center side of the disc and the reproduction surface from being damaged. Moreover, the structure is simple, and the entire disk case can be easily manufactured by integral molding of a synthetic resin, and can be provided at a low cost.
[0016]
In addition, since the case lid is provided with a locking boss that locks the other side edge of the circular arc shape of the disk when the case body is covered, the disk can be securely fixed and held, and the disk can be securely held. It can be prevented from coming off or wobbling. Furthermore, the tip surface of the locking boss provided on the case lid is tapered downward from the inside to the outside with the case lid covered, so that the tip surface of the locking boss is pressed so as not to come out of the disk and pushed toward the center. Since the disk is formed, the disk can be pressed inward by the tapered surface, and the disk can be stored in a securely fixed state so as not to come off. Further, since the disc can be held in a slightly floating state, it is possible to prevent the recording surface on the back side of the disc from being damaged.
[0017]
According to the second aspect of the present invention, since both ends of the substantially semicircular raised portion provided in the case main body are curved while being slightly biased toward the center, the arc groove of the raised portion is formed in the arc groove of the raised portion. When the disc is inserted, the upper and lower edges in the figure of the disc are pressed by the urging forces of both edges of the raised portion, and the disc can be firmly held.
