Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk cartridge storage case for storing a disk cartridge storing a recording disk such as an optical disk or a magneto-optical disk.

[0002]

2. Description of the Related Art Conventionally, a sleeve case is used as a case for storing a disk cartridge containing a recording disk or a tape cassette containing a tape reel around which a recording tape is wound.

The sleeve case is made of polypropylene (P
P) or a sheet material made of a synthetic resin such as polyethylene terephthalate (PET) is formed in a cylindrical shape, and an opening for inserting and removing a cartridge or the like is provided at one end. The disk cartridge and the like are inserted into and removed from the sleeve case through the opening.

[0004]

As described above, since the sleeve case is formed by bending a thin sheet material, it is not possible to form a sleeve case having sufficient rigidity.

If the case for accommodating the disk cartridge does not have sufficient rigidity, the disk cartridge cannot be reliably protected. When the sleeve cases are stacked in a state where the disk cartridges are stored, the sleeve cases may be deformed by the weight of the stored disk cartridges, which may cause deformation or damage to the stored disk cartridges.

Further, since the sleeve case does not hold the housed disk cartridge in the housed state, the sleeve case may come off due to vibration or impact. If the disk cartridge comes out of the sleeve case during transportation, it may be damaged due to a large impact.

Further, since the sleeve case is formed by bending a sheet material, the slit-shaped opening for inserting and removing the narrow disk cartridge is unstable and easily deformed. This makes it difficult to insert the disk cartridge.

Accordingly, the present invention has been proposed in view of the above-mentioned circumstances, and has sufficient rigidity to reliably protect a stored disk cartridge. An object of the present invention is to provide a storage case for a disk cartridge, which can reliably hold a storage state and can easily perform a disk cartridge insertion operation.
