DISCLOSURE OF THE INVENTION It is desired that a disc case used for, for example, music or reading materials has a distinctive design for individualization with other products.
If a convex portion is provided in the center of the lower case as in the conventional case, design restrictions are imposed, and the appearance is not very good.

Therefore, it is conceivable that the disc is accommodated in a paper tray having a flat bottom plate without the projections. However, damage to the recording surface due to contact between the bottom plate and the recording surface of the disc is considered. In order to prevent this, it is necessary to provide a soft protective sheet such as a nonwoven fabric on the bottom plate. In this case, even if beautiful printing is performed on the bottom plate, the printed surface is hidden by the protective sheet, so that a desired design cannot be utilized.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a disk case capable of securely holding a disk so as to protect a recording surface without providing a convex portion at the center of a bottom plate, and giving a sense of quality by printing or the like. Is to provide.

To store a disk in the disk case of the present invention, the tray is pulled out halfway from the outer case, and the disk is inserted into the disk storage recess of the tray. At the time of insertion, the leading end of the disc enters the inside of the tray while contacting the tray bottom plate from obliquely above, so that the leading end of the disc enters the gap between the terminal holding piece at the back of the tray and the bottom plate. .

[0007] The disk that is thus accommodated in the disk accommodating recess is supported with the recording surface slightly floating by contacting the lower surface of the peripheral edge with the supporting projection, so that the disk can be used without using a protective sheet such as a nonwoven fabric. Is protected. Then, the tip of the disc is held between the terminal holding piece and the bottom plate inside the outer case, and the disc surface is supported by the inner face of the outer case and the folded front portion of the tray. The movement is stopped.

When the tray is pulled out of the outer case to take out the disk, the tip of the protruding piece of the tray moves toward the opening of the outer case while being in contact with the inner surface of the outer case.
When the tray is pulled out to some extent, the projecting piece enters the back side of the stopper piece of the outer case, and the projecting piece and the stopper piece engage with each other, so that the tray cannot be further drawn out. Therefore, the tray is prevented from falling out of the outer case, and the disk in the disk accommodating recess is held at a predetermined position in the tray by the outer case, so that the disk is prevented from being accidentally dropped.

According to the present invention, as described in claim 2,
By making the outer case made of transparent plastic, the design may be further diversified. In this case, the tray may be made of transparent plastic.
