Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a CD and a CD-RO.
The present invention relates to a disk storage case for storing disk-shaped disks such as M and DVD.

[0002]

2. Description of the Related Art In general, disk-shaped discs such as CDs, CD-ROMs and DVDs are stored in a disc storage case when they are displayed at a store or when they are not used. This disc storage case is composed of a case body that holds the disc in a removable manner and a lid body that is rotatably connected to a side end portion of the case body.

Among such disc storage cases, one in which a holding portion for detachably holding a disc is integrally formed with the bottom plate of the case body is disclosed in Japanese Patent Publication No. 10-5025.
It is proposed in Japanese Patent Publication No. 99. As shown in FIG. 9, in this structure, two radial arms 53 extend inward in a cantilever manner from the outer side of the base portion (bottom plate) 51a of the case main body 51, and the inner end portions of these radial arms 53 extend inward. A semi-cylindrical segment 54 is erected at an interval. And these two segments 54 are connected by the living hinge 55 in the lower part, and form the button-shaped member 56. Further, from the base portion (bottom plate) 51a of the case body 51, four ejection arms 57 extend in the same manner as the radial arm 53 so as to bias the lower surface of the disk D upward. Further, as shown in FIG. 10, a lip 58 that engages with the outer upper surface of the central hole H of the disk D is provided on the outer periphery of the upper end of the segment 54.

When the disk D is taken out from the case body 51, the lid 52 is first opened, and the upper surface of the button-shaped member 56 is pushed down with a fingertip or the like, as shown in FIG. As a result, the two segments 54 are lowered while approaching each other, and the segments 54
The lip 58 on the outer periphery of the upper end of the disk is disengaged from the central hole H of the disk D, and the four ejection arms 57 push the disk D upward. Subsequently, the button member 56 is pushed down until the lip 58 passes the lower surface of the disc D, and then the pushing force for pushing down the button member 56 is released. As a result, as shown in FIG. 12, the disc D is placed on the inner tip portions of the four ejection arms 57, and the disc D can be taken out.

[0005]

However, in the above-mentioned conventional disc storage case, when the upper surface of the button-shaped member 56 is pushed down with a fingertip or the like, the two segments 54 come close to each other, and thus the two segments 54 are not separated. Your fingertips may be pinched and you may feel pain in your fingertips or damage your fingertips.

Further, since the four ejection arms 57 are provided so as to urge the lower surface of the disk D upward, the upper surface of the button-shaped member 56 is pushed downward with a fingertip or the like, and the upper end of the segment 54 is pressed. When the engagement between the outer peripheral lip 58 and the central hole H of the disk D is released, the disk D may jump up and damage the surface of the disk D. If the surface of the disc D is damaged, the information stored in the disc D may not be accurately read. Moreover, the holding portion has a structure including two radial arms 53, two segments 54, four ejection arms 57, etc., and is very complicated.

The present invention has been made in view of such circumstances, and when the disc is taken out, the fingertips are not caught,
Also, without damaging the surface of the disc,
The purpose is to provide a disk storage case having a simple structure.

[0008]

In order to achieve the above-mentioned object, a disc housing case of the present invention has a case body in which an annular holding portion is provided on an upper surface and a disc is held and fixed by an inner peripheral portion of the annular holding portion. And a lid body that covers the case body, wherein a convex portion and a spring piece are provided inwardly protruding from the inner peripheral surface of the annular holding portion, and the convex portion and the case body are The outer peripheral edge portion of the disc is inserted into the gap between the upper surface and the outer peripheral edge portion of the disc, and the elastic force of the spring piece urges the outer peripheral edge portion of the disc toward the convex portion to move the disc. The configuration is such that it is fixed.

That is, the disk storage case of the present invention comprises a case main body for projecting an annular holding portion on the upper surface and holding and fixing the disk at the inner peripheral portion of the annular holding portion, and a lid for covering the case main body. It is a disk storage case equipped with,
A convex portion and a spring piece are provided so as to project inward from the inner peripheral surface of the annular holding portion. The outer peripheral edge portion of the disc is inserted into the gap between the convex portion and the upper surface of the case body to hold the outer peripheral edge portion of the disc, and the outer peripheral edge portion of the disc is protruded by the elastic force of the spring piece. The disk is fixed by urging it in the direction of the part. As described above, in the disc storage case of the present invention, the convex portion and the spring piece are provided inward from the inner peripheral surface of the annular holding portion projecting on the upper surface of the case body, and the disc is held and fixed by utilizing these. Therefore, when removing the disc from the annular holding portion, the disc is fixed by moving the disc against the elastic force of the spring piece while operating the outer peripheral edge of the disc with a fingertip or the like. In addition to releasing, the holding of the disc is released by taking out the outer peripheral edge of the disc from the gap between the convex portion and the upper surface of the case body, and then the disc may be lifted upward. It is not pinched by springs or spring pieces, nor scratches the surface of the disc. Moreover, it is a simple structure in which the convex portion and the spring piece are provided so as to project inward from the inner peripheral surface of the annular holding portion.

In the present invention, when the convex portion and the spring piece are formed at positions facing each other, the elastic force of the spring piece can effectively act on the convex portion side.
