[0001]

[Technical field to which the invention belongs]

 The present invention relates to a disk-shaped recording medium storage device for storing a disk, which is a disk-shaped information recording medium, with the recording surface of the disk horizontal.

[0002]

[Prior art]

 Disc-shaped information recording media (herein referred to as "discs") are used in various fields. Such discs include magnetic discs and optical discs. In particular, optical discs such as CD-ROMs have high utility as portable large-capacity information recording media.

Conventionally, a disk magazine for storing a large number of optical disks has a drawback that the mechanism is large and complicated, so that it is expensive and easy to break down. Was bigger. On the other hand, in a disk magazine storing a relatively small number of sheets, the optical disk is stored in the disk magazine as it is as a standard cartridge, so that the disk magazine has a large shape and the thickness of the disk magazine is thick, and handling of the magazine is inconvenient.

[0004]

[Problems to be solved by the invention]

 As optical disks become more widespread, it is expected that the number of opportunities to use optical disks will increase in ordinary households in the near future. However, when a disk magazine is configured with standardized conventional disk cartridges, there is a limit in reducing the thickness of the entire disk magazine due to the thickness of the disk cartridge. On the other hand, in order to store a plurality of optical disks in a conventional disk magazine in a bare state, it is necessary to have a holding mechanism for contacting any part of the optical disk. Conventionally, a mechanism for holding the center hole of an optical disk is generally used, but the mechanism for inserting and ejecting the optical disk is complicated and the shape becomes large.

The present invention solves such a problem, and provides a lightweight, compact, and easy-to-handle disc magazine which can be used in ordinary households and can be marketed as a single disc magazine for storage and storage purposes, that is, a storage device for a disc-shaped recording medium. It is intended to provide. For this purpose, it is necessary to store multiple optical disks in a thin disk magazine equivalent to the cartridge of a general home video tape recorder in view of the purpose of use of this disk magazine. Disc holding structure is required.
