Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk housing case, and more particularly to a structure in which the housing case serves as a cartridge.

[0002]

2. Description of the Related Art As shown in the perspective view of FIG. 7, a conventional disc housing case has a disc 3 on the inner surface of a case body 31.
Although not shown in the drawing, the center hole of the disk 32 is locked and held by a cylindrical stair-like holding surface, and the lid 33 is opened and the upper part of the holding surface is pushed by a finger when not in use. Thus, the outer shape of the holding surface is tightened to reduce the size of the disk 32.
It was taken out and mounted on a drive device for reading or recording and used. According to these conventional techniques, the disk 32 is taken out from the disk housing case at the time of use, and the disk 32 is housed according to the above-described procedure at the time of housing. In particular, it is necessary to use one hand to perform these operations inside the moving vehicle, and it is easy to take them out.
