DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case for storing and storing a disk cartridge such as a magnetic disk and an optical disk.

[0002]

2. Description of the Related Art In recent years, optical disks, magnetic disks, and the like have been known as recording media. These discs
It is stored in a special plastic cartridge.
The storage of the disk cartridges is sold one by one in a plastic case. When a user purchases and stores a plurality of disk cartridges after purchasing, a plurality of disk cartridges are collectively stored in one separate case. Alternatively, a plurality of disc cartridges are stored in another large plastic case while being stored in a plastic case.

[0003]

However, when a plurality of disk cartridges, which have been widely used in the past, are put together in one storage case, there is a possibility that dust may enter and adhere from outside when the storage case is opened and closed. is there. In addition, when one of the discs is taken out and carried, the disc cartridge is in a bare state, and dust adheres to the disc cartridge. Further, when the disk cartridge is stored in a plastic case, it is troublesome to take out the disk cartridge, which is inconvenient.

An object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to arbitrarily remove one disk from a case in which a plurality of disk cartridges are stored and stored. An object of the present invention is to provide a disk cartridge storage case for storing a plurality of disk cartridges in which a cap for protecting a center rotating portion and the like is fitted without removing the removed disk cartridge without being naked.

[0005]

In order to achieve the above object, a disk cartridge storage case according to the present invention is characterized in that each rectangular disk cartridge is partially fitted with a plastic cap, and a plurality of plastic cartridges are provided. That the disc cartridge fitted with the cap is held on the upper side of the lower case, and that the portion of the disc cartridge not covered with the plurality of plastic caps is accommodated in the lower case. Features. Further, the invention is characterized in that the cap covers a shutter portion and a center rotating portion of the disk cartridge.

According to the present invention, one disk can be arbitrarily taken out of a case in which a plurality of disk cartridges are housed and stored, and the taken-out disk cartridge does not become naked and the center rotating portion and the like are removed. A storage case for a disk cartridge having a protected cap can be obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A disk cartridge storage case according to the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of a disk cartridge storage case according to the present invention, and FIG.
FIG. 3 is a perspective view showing a cap and a disk cartridge of an embodiment of the disk cartridge storage case according to the present invention; FIG. 3 is a perspective view showing a lower case of the embodiment of the disk cartridge storage case according to the present invention;
FIG. 4 is a schematic sectional view showing a cap of a storage case for a mini disk cartridge and a disk cartridge according to the present invention, and FIG. 5 is a schematic sectional view showing a storage case for a mini disk cartridge according to the present invention.

FIG. 1 is a perspective view showing an embodiment of a disk cartridge storage case A according to the present invention. As shown in FIG. 1, the disk cartridge storage case A has disk cartridges 1 fitted one by one. A plurality of plastic caps 2 and a lower case 10 in which a portion exposed from the plastic caps 2 for fitting the plurality of disc cartridges 1 is accommodated.

FIG. 2 shows a disc cartridge 1 and a plastic cap 2. The disc cartridge 1 is formed of a synthetic resin.
It has a rectangular shape. Inside, a disk 3 as a recording medium is rotatably accommodated. This disk 3 has a central rotating part 5. There is a recording / reproducing opening on one side, and the recording / reproducing opening can be opened and closed by a slidable shutter unit 4.

On the other hand, as shown in FIG. 2, the plastic cap 2 is provided with a shutter 4 which is a part for protecting the disk cartridge 1 from dust and the like, and a center rotating part 5, that is, the disk cartridge 1. 1 /
It is designed to protect two to two thirds.

As the material of the cap 2, for example, polypropylene resin, acrylic resin (such as polymethyl methacrylate), acrylonitrile-butadiene-styrene resin, polyvinyl chloride resin, polycarbonate resin, and polystyrene resin can be used.

The cap 2 has two inner side surfaces 9.
Is provided with an engagement projection 7. The recesses 6 provided on both sides of the disc cartridge 1
The disc cartridge 1 is simply prevented from falling from the cap 2.

Next, as shown in FIG. 3, the lower case 10 houses the disk cartridge 1 in which a plurality of caps 2 are fitted. Examples of the material of the lower case 10 include polystyrene resin, polyvinyl chloride resin, polypropylene resin, acrylic resin (such as polymethyl methacrylate), polycarbonate resin, polyester resin, polyamide resin, acetal resin, acrylonitrile-butadiene-styrene resin, and the like. For example, it can be manufactured by using a known molding method such as injection molding and extrusion molding.

When the disk cartridge 1 in which a plurality of caps 2 are fitted is housed, all the caps 2 are held on the upper side 11 of the lower case 10 and are held. Cartridge 1
The disk cartridge 1 is designed to be suspended by the cap 2 so that the disc cartridge 1 does not contact the bottom 13 of the lower case 10. Therefore, no load is applied to the disk cartridge 1 and no warping or the like occurs. Therefore,
By adjusting the size of the lower case 10, a storage case A for disk cartridges of various storage numbers can be manufactured.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS For example, when designing a case B containing five minidisks, as shown in FIG.
It becomes the form which covers. Specifically, the height of the cap 2 was set to 48 mm while the height of the mini disk cartridge 20 was set to 68 mm. Therefore, the 23 mm portion of the mini disc cartridge 20 is exposed from the cap 2.

The shape of the lower case 10 is designed to accommodate the portion of the mini disk cartridge 20 exposed from the cap 2 as shown in FIG. Cap 2
Is held by the upper side 11 of the lower case 10. Therefore,
The length of the lower case 10 is the same as the length of the cap 2,
80 mm. The thickness of the upper side portion 11 holding the cap 2, that is, the short side wall 13, was 3 mm. The lower end of the mini disk cartridge 20 is located at the bottom 1 of the lower case 10.
The height of the lower case 10 is designed so as not to reach
5 mm.

Further, as shown in FIG.
Was set to 1 mm similarly to the thickness of the front surface 8 of the cap. By making the lower case 10 having the above shape,
The portions exposed from the caps 20 of the five mini disk cartridges fit into the lower case 10, and the five caps 2 are held on the upper side 11 of the lower case 10. FIG.
-C is a diagram showing a state viewed from above.

[0018]

According to the present invention, a case in which a plurality of disk cartridges are stored and stored can be arbitrarily set to one.
The disc cartridge can be removed, and the removed disk cartridge has a cap that protects the rotating part of the center without being naked, so foreign matter such as dust adheres to the disk from outside when carrying it. Is preventing. Of course, even during storage, the attachment of foreign matter from outside is prevented.
