[0002]

2. Description of the Related Art Conventionally, a disk storage case has been used to store and transport a plurality of disk-shaped media such as compact disks not contained in a cartridge. Such a disk storage case usually has a main body having a bottom plate, a guide cylinder projecting upward from the center of the upper surface of the bottom plate, and being inserted into each center hole of a plurality of disk-shaped media stacked on the bottom plate. And a cover body having an outer peripheral wall and having a storage space for storing a plurality of disk-shaped media stacked on a bottom plate therein, and a means for locking the cover body over the main body.

[0003] Japanese Utility Model Application Laid-Open No. 62-90381 discloses that an independent screw is used as a locking means, and the screw is screwed into the leading end of the guide cylinder of the main body through the center of the upper plate of the lid at the time of locking. ing.

However, the former requires three parts of the main body, the lid, and the screw, so that the number of parts is increased. Further, the screw must be removed each time the disk-shaped medium is taken in and out, which is troublesome, and the screw may be lost. Further, since the main body and the lid are locked at only one position on the center line of the storage case, the bonding strength is weak and the strength is slightly inferior. Note that the guide cylinder is inserted through the center hole of the disk-shaped medium, and the thickness cannot be changed to increase the strength.

In this respect, in the latter, since the lower end of the outer peripheral wall of the lid is locked at a plurality of locations with the outer peripheral portion of the bottom plate of the main body, a stable coupling force can be obtained and the strength is superior to the former. However, since the locking positions at multiple locations are at the same height and the engagement timing is the same, the lid may be accidentally forgotten to lock, or even if locked, a shock may be applied to some beat, etc. When rotated, all locks are released at the same time. At this time, there is a possibility that the main body is tilted by the lid when the storage case is lifted or the lid is removed, or the lid comes into contact with the disk-shaped medium and is damaged.

The present invention has been made in view of such a conventional problem, and is composed of two parts, a main body and a lid, and a locking portion between the lid and the main body is arranged in the height direction of the storage case. It is an object of the present invention to provide a disk storage case that is dispersed and arranged at different positions, obtains a stable coupling force, ensures locking, and has excellent strength.

[0007]

In order to achieve the above object, a disk storage case according to the present invention has a circular bottom plate,
A body having a guide cylinder projecting upward from the center of the upper surface of the bottom plate and being inserted into each center hole of a plurality of disk-shaped media stacked on the bottom plate; a circular upper plate and an outer peripheral wall; And a lid provided with a storage space for storing a plurality of disk-shaped media stacked on the bottom plate.

The main body is provided with a plurality of first engaging portions on the outer peripheral portion of the bottom plate, and further provided with a second engaging portion on the distal end portion of the guide tube. A corresponding first engaged portion with which each of the first engaging portions can be engaged is provided, and a corresponding second engaged portion with which the second engaging portion is engageable is provided inside a central portion of the upper plate. An engaging portion is provided.

Further, by rotating the main body and the lid relatively, each of the first engaging portions is engaged with the corresponding first engaged portion, and the second engaging portion is engaged with the corresponding second engaged portion. It is preferable that the lid is locked to the main body by engaging with the engaged portion.

Further, the timing of engagement of each first engagement portion with the corresponding first engaged portion is different from the timing of engagement of the second engagement portion with the corresponding second engaged portion. Good.
