BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case for storing a disk-shaped disk such as a compact disk.

[0002]

2. Description of the Related Art Compact disc, CD-ROM, C
A storage case for a disk-shaped disk as a recording medium such as DI is known, for example, from Japanese Utility Model Laid-Open No. 60-15887. This type of conventional storage case has a rectangular holder body, a storage recess formed on the surface of the holder body with a diameter corresponding to the outer diameter of the disk, and a diameter corresponding to the center hole of the disk. A notch is provided at a plurality of locations around the concave portion for letting the middle finger or the like dive below the disk. A large number of slits are formed in the boss portion radially from the center of the boss portion, and the boss portion is reduced in diameter by pressing the boss portion. Is configured.

Therefore, when the center hole of the disc is aligned with the boss and the periphery of the center hole of the disc is pressed, the center hole is resiliently fitted to the boss, is retained by the boss, and is retained. Is housed in the housing recess. When removing the disc from the storage case, press the upper part of the boss downward with the thumb to reduce the diameter of the boss, and then dip the middle finger, etc. below the peripheral edge of the disc from the notch formed around the recess. This is done by lifting and pulling up.

[0004]

However, such a conventional storage case has a structure in which a disk is held by a boss portion which can be expanded and contracted. When removing the disk, the boss must be strongly pressed. If the boss is pressed strongly, the boss portion defined by the slit may be damaged, and thereafter, the disk may not be securely held. In addition, if the boss portion and the central hole are tightly fitted, the disk cannot be easily taken out. In addition, when the disk is taken out, the disk may be warped and the disk may be adversely affected.

Further, in such a holding structure, there is a concern that the elasticity of the boss portion is reduced by use for a long period of time (several years), and there is a concern that the pressing force to the central hole for holding the disk is lost. In recent years, like CD books,
In view of the fact that a disc is held between papers constituting a book and is distributed in the market, it has been desired to develop a simpler disc holding structure. The present invention has been devised in view of the above circumstances, and an object of the present invention is to provide a disk storage case that can securely store a disk with a simple structure and can easily remove the disk. .

[0006]

In order to achieve the above-mentioned object, a disk storage case according to the present invention comprises a substrate portion for protecting a disk, and a boss portion projecting from the substrate portion and inserted into a central hole of the disk. A stepped portion formed in an annular shape around the substrate portion around the boss portion, abutting against an inner portion of the recording surface of the disk to separate the recording surface of the disk from the substrate portion, and being provided protruding from the substrate portion; The boss portion is inserted into the center hole of the disk, and the inner portion of the recording surface of the disk is held in contact with the step portion at a plurality of positions spaced apart from the outer peripheral edge of the disk to hold the disk. At least three flexible claw portions, and an operation piece protruding in a direction away from the boss portion above at least one of the claw portions, wherein each of the claw portions is the substrate portion A vertical piece standing up from and below the vertical piece A step bulged inward at the same height as the step and an upper end of the vertical piece projecting from the upper end of the vertical piece, cooperating with a step inside the lower part of the vertical piece to form an outer peripheral edge of the disk. And a convex portion sandwiched in the thickness direction.

[0007]

The disk is stored by holding the outer peripheral edge of the disk on the substrate with at least three claws. The removal of the disk is easily performed by pressing the operation piece to bend the claw radially outward of the disk and pressing the disk portion opposite to the bent claw.
