TECHNICAL FIELD OF THE INVENTION
The present invention relates to a case for an optical disc such as a compact disc and a digital versatile disc, and more particularly to a disc case having a disc folder.
[0002]
[Prior art]
A disk-shaped (disk-shaped) recording medium case such as a CD (compact disk) and a DVD (digital versatile disk) usually has a columnar convex portion for fixing the disk, and the convex portion is located at the center of the disk. The holes are fitted and fitted.
[0003]
For this reason, if there is an error in the diameter of the convex portion and the fitting is too tight, it is difficult to remove the disk from the case, and further, when removing the disk, a large force is applied to the disk, which may cause distortion. Therefore, at the time of recording / reproducing, distortion of the disk appears as a runout, which leads to a decrease in recording / reproducing performance.
[0004]
Further, in the conventional case, the disc is directly held by hand, and there is a possibility that a deposit such as a fingerprint or dirt may be left on the recording surface of the disc, which also decreases the recording / reproducing performance. It will be connected.
[0005]
Therefore, there has been conventionally known a disk cartridge in which the disk can be easily taken out without directly touching the disk and the reproduction / recording performance can be prevented from deteriorating (for example, see Patent Document 1). 1).
[0006]
Separately, there has been conventionally known a case in which a tongue piece is provided on a lid of a case so that a disk can be taken out from a convex portion of a case body (for example, see Patent Document 2). .).
[0007]
Further, in addition to the above, a tray in which a disk is held by a pair of arms is conventionally known (for example, see Patent Document 3).

[Problems to be solved by the invention]
Although the prior art described above takes care to prevent a finger or the like from touching the disk, it has the following problems.
[0012]
First, in the case of the above-mentioned disc cartridge, it is necessary to provide a mechanism for writing and reading signals in a state where a disc is stored in the disc cartridge, and the reproducing / recording apparatus side must have a mechanism. This may lead to an increase in cost, and there is a risk that a finger or the like may come into contact when returning the disk to the case.
[0013]
In addition, in the case of the above-mentioned disk case, since the disk is sandwiched between the tongue pieces, it is inevitable that the tongue pieces come into contact with the recording / reproducing surface, and there is a possibility that a problem may occur in the deterioration of the disk reproduction / recording performance. There is.
[0014]
Further, in the case of the above-mentioned tray, when setting the disc in the reproducing / recording apparatus, the disc is manually removed from the lid of the case. Therefore, there is no problem or influence on the insertion of the disc. When returning the disc to the case, it would be extremely difficult to work without touching it directly.
[0015]
