Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a protective case for a disc cartridge for protecting a disc cartridge housing a disc-shaped record carrier.

[Prior Art] In recent years, disc-shaped recording media such as optical discs have been used frequently, and at the same time, recording media such as VHDs in which recording media are housed in disc cartridges have been used more frequently. Therefore, in order to prevent disk cartridges from getting dirty or being damaged during storage or transportation, it has been considered to store them in a protective case.

FIG. 2 is a perspective view of a conventionally used protective case I and disk cartridge D. The protective case 1 is constructed by overlapping a substantially rectangular bottom part 2 and a lid part 3, and by connecting one side of these parts by a shaft part 4, the lid part 3 can be freely rotated with respect to the bottom part 2. ing. Further, the substantially rectangular disk cartridge D is housed so that the spine label L is in contact with the opposite side of the shaft portion 4 . A wall 5 is provided at the edge of the bottom 2 and the lid 3, but in order to make it easier to take in and take out the disk cartridge D, the front 6 of the bottom 2 is not provided with a wall, but is instead provided with a lid. The front wall portion 7 of No. 3 is made larger so as to enclose the disk cartridge D. Further, in this case, the front wall portion 7 is formed of a transparent member so that the back label L of the disk cartridge D housed inside can be seen through. Furthermore, stepped portions 8 are provided at four locations, two on the left and right sides of the inner edges of the bottom portion 2 and the lid portion 3, so that the surface of the disk cartridge D comes into contact with the inner surface 9 of the bottom portion 2 and the lid portion 3 to prevent scratches. It looks like this.

The conventional protective case l is formed in this way, but when the user wants to take out the disk cartridge D from the protective case l, the user opens the bottom part 2 with the front part 6 of the protective case l tilted downward. If this occurs, the disc cartridge D may slip down, and there is a risk that the disc cartridge D and the recording medium inside may be damaged.

In order to prevent this, it is conceivable to arrange a wall 10 on the front part 6 of the bottom part 2 as shown in FIG. Because it gets stuck, it becomes troublesome to take it out. Further, in order to see through the back label L of the disk cartridge D, this wall portion 1O must also be made transparent, which poses problems such as a cumbersome design.

[Object of the Invention] An object of the present invention is to solve the above-mentioned problems and to provide a protective case for a disc cartridge that is easy to handle and safe even when the disc cartridge is stored in a transport number.

[Summary of the invention] The gist of the present invention is to achieve the above objects.

A protective case for accommodating a disc cartridge consisting of a bottom part and a lid part and having a recessed part on the side surface, characterized in that a convex part that fits into the four parts of the disc cartridge is provided on the inner surface of the bottom part. It is a case.

[Embodiments of the Invention] The present invention will be explained in detail based on the embodiment shown in FIG.

FIG. 1 is a perspective view of a protective case 1 and a disk cartridge D, and the same reference numerals as in the conventional example indicate the same members. On the left and right sides of the disc cartridge D, there are recesses A that are originally provided in order for the disc autocharger installed inside the information recording/reproducing apparatus (not shown) to grip the disc cartridge D when the disc is loaded into the information recording/reproducing apparatus (not shown). exists.

Therefore, when the disk cartridge D is housed in the protective case I, a convex portion 11 is protruded from the inner surface 9 of the bottom portion 2, which is in contact with the aforementioned concave portion A. One protrusion 11 is provided on each side, and the disk cartridge D is positioned with respect to the bottom 2. In addition, this convex portion 11
is formed into a semicircular shape with a rounded top, so that when storing the disk cartridge D, the convex portion 11 and the concave portion A can be easily fitted together.

Therefore, even if there is a gap between the disc cartridge D and the protective case 1, it is possible to prevent the disc cartridge D from moving inside the protective case 1 during transportation or storage and from being scratched due to frictional contact. Furthermore, even if the protective case 1 is tilted forward with the lid 3 open, there is no risk that the disk cartridge D will slip because the convex portion 11 is secured to the concave portion A.

Note that the convex portion 11 does not need to be provided on both sides of the bottom portion 2, and the same effect can be obtained even if it is placed only on one side.

[Effects of the Invention] As explained above, the disk cartridge protective case according to the present invention enables stable storage by providing the bottom of the protective case with convex portions that fit into the four portions provided on the sides of the disk cartridge. This also prevents the disc cartridge from falling out of the protective case when taking it out.
