Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is a case for storing a disc-shaped recording medium such as a CD or DVD. Even when the storage case is deformed by an external pressure, the disc-shaped recording medium does not come off from the thigh (engagement convex portion). It is related to the storage case devised.
[0002]
[Prior art]
A disc-shaped recording medium such as a CD or a DVD is placed in a thin storage case including a main body case (A) and a lid case (B). FIG. 8 shows a conventional storage case in a state where a lid case is opened, and a disk-shaped recording medium (C) is attached to the main body case (A). An engagement projection (e) protruding from the base surface (d) is provided at the center of the main body case (a), and this engagement projection (e) is fitted into the center hole of the disc-shaped recording medium (c). By combining, the disc-shaped recording medium (C) is attached, and the lid case (B) is closed in this state.
[0003]
FIG. 9 shows a cross section with the lid case (b) closed. By the way, the disc-shaped recording medium (C) has a configuration in which an engaging convex portion (E) is fitted and attached to the center hole, and the disc-shaped recording medium (C) is engaged with the center hole of the disc-shaped recording medium (C). Align with the convex part (e) and press from above. On the other hand, when removing, the upper surface of the engaging convex portion is pressed to bend and deform and can be separated from the central hole.
[0004]
The engagement projection structure (engagement projection configuration) provided so as to protrude from the base surface (d) of the main body case (b) is also devised in various ways so that the disk-shaped recording medium (c) can be easily attached and removed. However, this also makes it easy to come off at any time. That is, a situation occurs in which the main body case (b) or the lid case (b) is deformed and the disc-shaped recording medium (c) is detached from the engaging convex part (e) alone. As shown in FIGS. 8 and 9, the central portion of the base case (A) has an engaging convex portion (e) at the center portion and a mounting portion (e) around the engaging convex portion (e). F). The disc-shaped recording medium (c) is placed on the mounting part (f) and the central hole is fitted to the engaging convex part (e). The outer periphery is supported on the outer periphery (g).
[0005]
Therefore, as shown in FIG. 10, when a pressing force acts from above the lid case (b) to bend and deform, the lid case (b) hits and presses the upper surface of the engaging projection (e). Become. As a result, the engaging projection (e) contracts and comes out of the central hole of the disc-shaped recording medium (c). That is, the same phenomenon occurs when the disc-shaped recording medium (c) is removed from the engaging projection (e). Once removed, the center hole will not fit into the engaging projection (e), and the disc-shaped recording medium (c) will be rattled in the storage case, causing scratches on the surface, resulting in disc-shaped recording. The function as a medium (c) is lost, and recording and reproduction cannot be performed.
[0006]
[Problems to be solved by the invention]
Thus, the conventional storage case has the above problems. The problem to be solved by the present invention is this problem. The disc-shaped recording medium prevents the disc-shaped recording medium from being detached by itself by pressing the engaging convex portion even when the lid case is bent and deformed inward. A medium storage case is provided. The storage case of the present invention can be used for both sales and rental.
