Is provided.

Next, the operation of storing the disk D in the disk storage case of the present embodiment will be described. First, the lid 20 is removed from the case body 10 and the bottom surface 30 of the case body 10 is opened. In this state, inserting the raised portion 33 to the central opening D ₀ of the disc D. The disk D descends along the inclined surface 36 of the raised portion 33 until the lower surface contacts the ring-shaped projections 31 and 32. The remains disc D is simply lowered, the peripheral edge portion D ₁ of the disc D as shown in FIG. 6 is projected outward beyond the notch 17 of the front side wall 11 _F.

Next, the lid 20 is attached to the case body 10. When the lid 20 is mounted, the guide projection 25
After the lid 20 is lowered by fitting the
Is performed by sliding the guide projection 25 along. At this time, the lid 20 slides in the mounting direction I,
The outer peripheral part D _{1 of the} disk D protruding outward is
It is pushed into the disc housing space side 0 of the front side wall 23 _F. The lid 20 is provided with the engagement projections 1 on the engagement recesses 26 _R and 26 _L.
The slide is performed in the mounting direction I until the 4 _R and 14 _L are fitted.

Also, the rear outer peripheral portion D ₂ of the disk D displaces the repression head 45 rearwardly against the elastic restoring force of the arm 44 as shown in FIG. However, the reaction force caused by the displacement of the resilient head 45 is caused by the engagement protrusions 14 _R and 14 _L and the engagement recesses 26 _R and 2.
By meshing with 6 _L is received by the front side wall 23 _F of the lid 20 which is fixed to the case body 10. When mounting the lid 20, the printed matter S can be stored together with the disk D. At this time, since the amount of movement of the lid 20 with respect to the case main body 10 is small, the printed matter S is stored at a regular position without wrinkles or waist breaks.

Therefore, when the lid 20 is moved to the closed position, the disk D is supported by the ring-shaped projections 31 and 32 while slightly rising from the bottom surface 30 without rubbing the upper surface. And the peripheral part D
_1, the rear outer peripheral portion D ₂ and the front side wall 23, respectively to the front inner peripheral edge portion D _{3 F,} by the eaves portion 42 and the restricting portion 34 is pressed against and is maintained in position in the disc accommodation space. Further, the lid 20 is securely fixed to the case body 10 because the engagement projections 14 _R and 14 _L are fitted into the engagement recesses 26 _R and 26 _L.

When taking out the stored disk D, the engaging projections 14 _R and 14 _L and the engaging recesses 26 _R and 26 _L
Is released, and the lid 20 is slid rightward in FIG. The sliding of the lid 20, away front side wall 23 _F from the periphery portion D ₁ of the disc D, the force to push the disc D is released. As a result, the arms 44 of the detachable mechanism 40 is elastically restored, push the rear outer peripheral portion D ₂ of the disk D in repression head 45 as shown in FIG. 8 (b) the dotted line position D _4. By an elastic restoring force of the arm 44, the rear outer peripheral portion D ₂ is escape from between the eaves portion 42 and the bottom portion 30, the front inner peripheral edge portion D ₃ escape from between the restraining portion 34 and the bottom portion 30. As a result, the disk D enters an unrestricted free state. Further, the peripheral edge portion D ₁ protrudes slightly outward from the front side wall 11 _F of the notch 17, as shown in FIG. Therefore, with the peripheral edge portion D ₁ which protrudes, it is possible to remove the disc D with ease.

In either case of storing the disk D or removing the stored disk D, nothing rubs the upper surface of the disk D. Therefore, no defect such as a flaw is generated on the upper surface, and the recorded information is stored in the initial state. Moreover, the lid 20
When attaching / detaching, the slide amount of the lid 20 is small, so that it is easy to store the printed matter by overlapping the disk. In addition, since the case body 10 and the lid 20 are transparent, the presence or absence of the disk D and the printed matter S can be easily confirmed, and the printing performed on the disk D itself can be easily seen.

[0020]

As described above, in the disk storage case of the present invention, the disk is stored with a small sliding amount without rubbing the upper surface of the disk. Therefore, even if storage and retrieval are repeated, recorded information can be reproduced in the initial state without damaging the disk surface. Further, it is possible to easily store the printed matter in a state of being superimposed on the disk without causing wrinkles, waist breaks, and the like. In addition, since the disk is in the restrained state or the free state in accordance with the sliding of the lid, the operation of releasing the elastic force or the like seen in the case incorporating the spring or the like becomes unnecessary when storing and removing the disk. Further, the lid can be easily attached to and detached from the case main body, and the disc is maintained at a fixed position in the stored state.
