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

[0002]

2. Description of the Related Art Compact disc, CD-ROM, C
A structure for holding a disk-shaped disk which is a recording medium such as DI is known, for example, from Japanese Utility Model Laid-Open No. 60-15887. A conventional holding structure of this type is formed of a rectangular holder body, a receiving 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, if the center hole of the disk is aligned with the boss portion and the periphery of the center hole of the disk is pressed, the center hole is resiliently fitted to the boss portion and is prevented from coming off by the boss portion.
The entire disc is housed in the housing recess and held. When removing the disc from the holder body, press the upper part of the boss part downward with your thumb to reduce the diameter of the boss part, and 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, since such a conventional holding structure is a structure for holding a disk with a boss portion which can be expanded and contracted, when the fitting between the boss portion and the central hole is tight, 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. Also,
If the boss and the central hole are tightly fitted, the removal of the disk will not be easy, and when removing the disk,
There is also a problem that the disk is warped and the disk is 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 holding structure that can reliably hold a disk by a simple structure and that can be easily removed. is there.
