This invention relates to a disk storage case that is stored and placed in a shape.

[Background technology and its problems]

2. Description of the Related Art Conventionally, an automatic disk playing device has been used which selectively takes out and plays a large number of disks, such as record disks, stored in a disk storage section. The disks to be played in this type of automatic performance device are each stored and mounted in a disk storage case, and the disk storage cases are inserted into a disk storage section formed in the shape of a housing in a multi-tiered manner so as to be freely removable. , the applicant has proposed a device that is stored and held in this disk storage section. Since a large number of the disk storage cases are stored in the disk storage section according to the number of disks, the disk storage case is lightweight and made of, for example, plastic material, so it is important to note that the total weight is large. It was designed to be avoided. Further, the disc is stored in a state in which it is simply placed in a storage recess formed in the disc storage case, and can be easily separated from the disc storage case during performance.

By the way, the disk storage part in which the disk storage case formed in this way is stored is formed by, for example, injection molding of plastic material, so there may be some errors caused during processing or subtle changes due to temperature changes. In consideration of expansion and contraction, the insertion portion of the disk storage case is designed to have a slight gap in advance. However, if such a gap is provided, a certain gap will be formed between each disk storage case stored in this disk storage section, and in particular, the automatic performance device may be affected by external disturbances. If the disk storage cases and the disks stored there shake, the gaps between the disk storage cases will become larger, and the thin plate-shaped disks will come out of this gap. It has the disadvantage that it can pop out and fall out of this disk storage section. There is also a risk that this dropped disk may damage other equipment in the automatic performance device.

In particular, in the above-mentioned automatic performance device, it is common for the disk and the disk storage case to be immediately stored in the disk storage section while being transported, and vibrations during transportation may cause Falling of the disk from the disk storage portion cannot be easily avoided.
