BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover case which can accommodate disc shaped record media such as CD, DVD, game software, etc., can be attached stably, and can be easily removed.

Disc shaped recording media such as CDs have a thin disc shape and have a small circular hole in the center thereof. The disc-shaped recording medium is housed in a thin cover case, which is composed of a box-shaped main body having a base side lightest surface and a cover having a cover side lightest surface. The cover is connected to the main body via a joint and can cover the main body. Of course, there are some cover cases that do not have the above seam, and there are also cover cases in which the main body is drawn out in a withdrawal form.

By the way, the disk-shaped recording medium is attached to a holding portion provided to protrude from the center of the base of the main body to a hole provided in the center of the disk-shaped recording medium. The shape of this holding part is known in various ways, and it is required that the disc-shaped recording medium fitted in the hole be functioned so as not to be rattled and stable, of course, not to fall out, but to be easy to be pulled out when taken out.

The "compact disk holding device" according to Japanese Patent Laid-Open Publication No. 2002-539578 is "a base portion and a radial arm which is formed elastically from the base and the base and extends inwardly, and the center hole of the disk is openable. In order to engage and separate from the base to support the central portion of the disk, a disk engaging means is provided at the inner end of the arm. Each arm has a first rotating means positioned in an area engaged with the base and a second rotating means positioned radially inward from the first rotating means. By pushing down the disk engaging means towards the base, the inner end of each arm and the central portion of the disk are pressed down towards the base, each arm initially rotating about the first pivoting means, and then the disk engaging means. Rotates around the second rotating means until the holding force of the disk is released. &Quot;

The disc is engaged with the engaging means in the center hole. When the disc is pulled out, it is necessary to press the engaging means engaged with the hole from above and detach it from the hole. Acting and bending. As a result, a problem often occurs when the disc is ejected. However, in order to make it easier to pull out, when the engaging means is loosely fitted in the disc center hole, the disc in the stored state will come out by itself.

Such a problem is not limited to the "holding apparatus for compact disks" according to Japanese Patent Laid-Open Publication No. 2002-539578, and the "apparatus for holding a compact disk" according to Japanese Patent Laid-Open Publication No. 2000-508997, Japanese Patent Publication No. 10 The same problem arises also in the "apparatus holding a compact disk" concerning -502599.

As described above, the cover case of the conventional disc-shaped recording medium has the same problem as described above. SUMMARY OF THE INVENTION The problem to be solved by the present invention is this problem, and provides a cover case of a rental or sales recording medium which is stable because the disc-shaped recording medium stored there is no rattling and can be removed without overdoing it.

Fig. 1 is an embodiment showing a cover case of a recording medium according to the present invention, where 1 is a main body and 2 is a lid. The main body 1 has a box shape having a base side lightest surface, the cover 2 has a cover side lightest surface, and the cover 2 is connected to the main body 1 through a joint 3. Thus, the main body 1 can be covered. At the center of the base surface 4 of the main body 1, a support pedestal 5 is projected, and the outer periphery edge 6 is protruded and installed around the support pedestal 5, and the periphery edge 6 Cutouts 7 and 7 are formed in four places.

And arm 8a, 8b is formed in the mounting surface 13 of the said support base 5, and the support base 5 is slit by the slit grooves 9 and 9, and the arm tip is outlined. It protrudes from the semicircular engaging protrusions 10a and 10b. Thus, a gap is interposed between the convex convex portions 10a and 10b so as to be contracted. The convex convex portions 10a and 10b are combined to form a lower circumference, and the convex convex portions 10a and 10b are fitted to the disk center hole and engaged. . In addition, the release preventing click 11 stands up from the base surface 4 at the joint side, and the tip of the click 11 is located at a position where a part of the outer peripheral edge 6 is cut off and placed on the outer peripheral edge 6. When the lid 2 is closed, the back of the release preventing click 11 is pressurized so as not to be pulled out.

2 (a) shows the receiving pedestal 5, and since the arms 8a and 8b are jointed by the slit grooves 9 and 9 from the receiving pedestal 5, the engagement projections 10a and 10b are shown. Pressing) can bend and deform. Fig. 2 (b) shows a cross section in which the disk 12 is attached to the support base 5, which is placed on the mounting surface 13 of the support base 5 and at the same time convex convexity. The portions 10a and 10b are engaged by being fitted in the center hole of the disk 12.

The disk 12 may be mounted on the receiving pedestal 5 so that the engagement protrusions 10a and 10b are fitted into the center hole, and FIG. 3 (a) is attached to the receiving pedestal 5 by placing the disc 12 on the receiving pedestal 5. This is the case. When the disk 12 is placed on the receiving pedestal 5, the edges of the engagement protrusions 10a and 10b are tightly pressed against the inner circumferential surface of the disk center hole, and the arms 8a and 8b are flexibly deformed as shown in the figure. do. As a result, the engagement protrusions 10a and 10b can contract and fit in the center hole. Since some clearance is interposed between both engagement convex parts 10a and 10b, it can shrink | contract in this way.

The state pinched by the center hole is a state shown in Fig. 2 (b). When the arms 8a and 8b return to their original positions and once the contracted convex portions 10a and 10b that have been contracted are enlarged, they are placed in the center hole. Is fitted. In this manner, the arms 8a and 8b are flexibly deformed and can be attached to the support base 5 without difficulty on the disk 12. The outer periphery of the disc is carried by the outer periphery 6, and the outer periphery 6 has a support surface for supporting the outer periphery of the disc.

On the contrary, when the disk 12 is pulled out from the receiving base 5, as shown in FIG. 3 (b), the engagement protrusions 10a and 10b are pressed from above. When pressurized, the arms 8a and 8b flexure and deform, and the engagement protrusions 10a and 10b contract. In this case, the disk 12 is mounted on the mounting surface 13 of the support base 5, so that the center portion of the disk 12 does not bend even when the engaging projections 10a and 10b are pressed.

Then, once the engagement convex portions 10a and 10b are contracted and removed from the disk center hole, the disk 12 is simply pulled out without being inserted into the center hole again. When the central portion of the disk 12 is mounted by being attached to the receiving pedestal 5, the disk outer circumference is supported by being loaded on the outer circumferential edge 6 which protrudes from the base surface 4 of the main body 1. In addition, since the notches 7 and 7 are formed in various places of the outer peripheral edge 6, it is also possible to lift and remove the disk 12 by inserting a finger into the notches 7.

4 shows that the disk 12 is mounted on the receiving pedestal 5, and the outer circumference thereof is supported on the outer circumferential edge 6 to be supported. A case is shown in the outer periphery of. The disc outer circumference is supported by being carried by the outer circumferential edge 6 and held by the release preventing click 11 standing on the base surface 4 as shown in the figure. And when the cover 2 is closed, the restraining piece 14 which protrudes and is provided in the joint part 3 can contact and support the back surface of this fall prevention click 11, and the disk 12 is spontaneous. There is no fall out from the engagement protrusions 10a and 10b. Here, the restraining piece 14 does not necessarily need to be attached to the joint part 3, and may be formed in the cover itself depending on the shape of the cover case.

Fig. 5 is another embodiment showing the cover case of the disc-shaped recording medium according to the present invention. The basic form is the same as that of the cover case shown in FIG. 1, the main body 1 has a box shape having a base side lightest surface, the cover 2 has a cover side lightest surface, and the cover 2 is It is connected to the main body 1 via the joint part 3, and can cover this main body 1 with it. At the center of the base surface 4 of the main body 1, a support pedestal 5 is protruded, and the periphery edge 6 is protruded and installed around the support pedestal 5, and the periphery edge 6 is formed. Cutouts 7 and 7 are formed in four places.

FIG. 6 is an enlarged view of the receiving pedestal 5 of the cover case shown in FIG. 5 and shows a plan view. The arms 15a and 15b are cut off by the slit grooves 16 and 16 from the mounting surface 13 of the support base 5, and project the engaging projections 17a and 17b to the tip of the arm. The engaging projections 17a and 17b are connected by a soft resin, and have engaging clicks 18a and 18b standing up in pairs, and the engaging clicks 18a and 18b are formed of the engaging projections 17a and 17b. Although extending from the arm as part, the engaging clicks 18a, 18b can bend independently of the arms 15a, 15b.

In this support base 5, the engaging clicks 18a and 18b are located at the cutouts formed in the engagement protrusions 17a and 17b, and stand up, but are bent independently of the arms 15a and 15b. It can deform and latch to the center hole of the disk 12. However, when the disk 12 is mounted on the receiving pedestal 5 and pressurized, as shown in Fig. 7 (a), the engagement clicks 18a and 18b standing up in pairs with the engagement protrusions 17a and 17b are It bends, fits in a center hole, and locks so that the disk 12 may not come out.

Since the engagement clicks 18a and 18b can bend and deform independently of the arms 15a and 15b, the engagement clicks 18a and 18b can be simply inserted into the disc center hole and locked. That is, FIG. 8 (a) shows the case where the disk 12 is placed on the receiving base 5 and attached. When the disc 12 is mounted on the support base 5, the ends of the engaging clicks 18a and 18b are pressed into the inner circumferential surface of the disc center hole and pressed down, and the arms 15a and 15b are bent and deformed as shown in the figure. . As a result, the engagement protrusions 17a and 17b and the engagement clicks 18a and 18b can be contracted and fitted into the central hole. Since some clearance is interposed between both engagement convex parts 17a and 17b, it can shrink | contract in this way.

On the contrary, when the disk 12 is pulled out, as shown in Fig. 8 (b), when the engagement projections 17a and 17b fitted to the center hole are pressed, the arms 15a and 15b are warped and deformed. At the same time, the engaging clicks 18a and 18b move together with the engaging projections 17a and 17b toward the center and are removed from the central hole. Once removed from the center hole, even if the finger is removed from the engaging projections 17a and 17b and returned to the original position, the center hole is not engaged again.

By the way, although the disk storage case of the said embodiment consists of a main body and a cover, and this cover is made into the form connected through the joint part, the form of the cover case of this invention is not limited.

Fig. 9 shows another form of the cover case, in which the lid can be opened and closed without having a joint. For example, a thinner hinge may be formed or connected through an axial pin. 10, the main body 1 may be stored in the cover case 19. Of course, the base and the outer circumference of the main body is formed to protrude from the base surface is the same.

As described above, the cover case of the present invention is provided with a support base provided at the center of the base surface of the main body with the disc center protruding from the center of the disc and protruding the engagement convex portion fitted into the center hole. It is installed by protruding the outer periphery of which the outer periphery is supported, and the following effects can be obtained.

In the cover case of the present invention, the center portion of the disc-shaped recording medium is mounted on the support pedestal provided on the main body, and the outer periphery is supported by the outer periphery. The arm has a pair of arms on the support base, and the engaging projection is standing on the tip. Since the arm is separated from the mounting surface of the support base via the slit groove, the arm can be flexibly deformed.

Thus, in the case of attaching the disk, if the engaging projection is tightly pressed into the center hole and pushed down, the arm may bend and both engaging projections may contract and fit into the central hole. On the contrary, when the disc-shaped recording medium is pulled out, the engaging convex portion inserted into the hole is bent so that the arm is bent and the engaging convex portion contracts and disengages from the central hole. At this time, since the disk is supported by being mounted on the mounting surface of the support base, the disk is not curved, and the disk is prevented from being damaged. By providing the engaging click on the engaging convex portion, attachment and detachment of the disk is made smoother, and the attached disk is stabilized.
