Description

  The present invention relates to a storage case for a disk-shaped recording medium that can store two disk-shaped recording media such as CDs, DVDs, and game software, and can be changed to store one disk if necessary.

  A disc-shaped recording medium such as a CD has a thin disc shape and is provided with a small circular hole in the center. The disc-shaped recording medium is stored in a thin storage case, and the storage case is composed of a box-shaped main body having a base-side widest surface and a cover having a cover-side widest surface. The lid is connected to the main body via the connecting portion and can cover the main body. Of course, there are cover cases that do not have the connecting portion, and there are also storage cases in which the main body is pulled out by a drawer type.

  By the way, the disc-shaped recording medium is attached by fitting a holding portion protruding from the central portion of the base of the main body into a hole provided at the center of the disc-shaped recording medium. The shape of the holding portion is known in various ways, but the disk-shaped recording medium fitted in the hole is stable without rattling, and of course, does not come off, but functions so that it can be easily removed when removed. Is required.

  If the disc-shaped recording medium comes off from the holding portion, there is a risk that the disc-shaped recording medium itself may be damaged due to play in the case and scratches on the recording surface. On the other hand, there is a storage case configured to be able to store two disc-shaped recording media. If a partition plate is provided by storing two sheets in the same case, the storage case The thickness becomes large. However, when two disc-shaped recording media are accommodated in the same space without providing a partition plate, the frequency of occurrence of scratches due to rubbing against each other by detachment from the holding portion increases.

  The applicant has filed a patent application for a “storage case for recording media for rental or sale” on February 21, 2003 (Japanese Patent Application No. 2003-44292). The “storage case for recording medium for rental or sale” is “a storage case for storing a disc-shaped recording medium such as a CD,” and a plurality of engagements that fit into the central hole of the disk-shaped recording medium at the center of the base surface of the main body. Elevating claws are raised, and a plurality of engaging claws that fit into the center hole of another disc-shaped recording medium are also raised at the center of the base surface of the lid. A storage case for a recording medium for rental or sales characterized in that the engagement claw standing on the base surface of the claw and the lid is engaged with each other and prevented from being bent and deformed toward the center side.

The storage case capable of storing two sheets targeted by the present invention not only stabilizes the disc-shaped recording medium stored and held by the holding unit without rattling, but can be changed to a storage case for one sheet. It was made possible.
CDs and DVDs are overwhelmingly one, but there are also two-disc sets. The lending storage case is prepared for 1 sheet and for 2 sheets. The storage case for 1 sheet is provided with a holding portion at one place, and the storage case for 2 sheets is provided at 2 places on the main body and the lid. A holding part is provided.

  As a rental shop, we have prepared both rental storage cases for 1 sheet and 2 sheets, but the ratio of 1 set to 2 sets in the store may change. It is difficult to match the number of recording media. In this case, it is possible to prepare a large number of rental storage cases for two sheets and use them as a rental storage case for one sheet.

However, when a disc-shaped recording medium is accommodated in a rental case for two discs, a question arises because the borrowed customer does not know whether it is a single disc set or a double disc set. Since the disc-shaped recording medium can be attached to either the main body side or the lid side when returning, the disc-shaped recording medium accommodated in the rental case is managed by a bar code in the rental shop. The position of is important. That is, when a disc-shaped recording medium is attached to the opposite side and returned, the barcode becomes difficult to read.
"Storage or storage case for recording media for rental or sale" according to Japanese Patent Application No. 2003-44292

  As described above, when the “rental or storage recording medium storage case” according to Japanese Patent Application No. 2003-44292 of the above-mentioned two-disc set is used as a single rental case, there are the above-mentioned problems. The problem to be solved by the present invention is this problem, and even if one disc-shaped recording medium is accommodated in a case that can accommodate two disc-shaped recording media, the customer is questioned. Provide a case that can be stored in the correct position when returned.

  The storage case for a disc-shaped recording medium according to the present invention includes a main body and a lid, and the lid can cover the main body. A holding portion is provided in the base central portion of the main body and the base central portion of the lid, and the central portion of a disc-shaped recording medium such as a compact disc is held. Here, although the specific form of the holding part is not limited, it has an engaging convex part, and the engaging convex part fits into the central hole of the disc-shaped recording medium so as not to be easily detached and removed. Consists of a support structure that can be easily detached.

  By the way, the storage case according to the present invention can store two disc-shaped recording media, but can be changed to one if necessary. Therefore, a cover is attached to the holding portion to which the disc-shaped recording medium is attached so that the disc-shaped recording medium cannot be attached to the holding portion. In addition, the holding part of either the main body or the lid can be removed. The form of the holding part cover is not particularly limited, and the specific attaching / detaching structure of the holding part is also free.

  The storage case for the disk-shaped recording medium according to the present invention can store two disk-shaped recording media, and can store one disk-shaped recording medium as required. However, when used for a single sheet, a cover can be attached to the holding portion to which the disc-shaped recording medium is attached, so that the disc-shaped recording medium cannot be attached to the holding portion.

  Further, by removing the holding portion, it is possible to prevent the disk-shaped recording medium from being attached. Therefore, even if the storage case is for two sheets, it is possible to store one disk-shaped recording medium, and since only one type of mold is required, the mold cost is reduced. The storage case management is convenient because it is not necessary to distinguish between one case and two cases. Further, when used for one sheet, the disc-shaped recording medium cannot be attached to one holding portion, so that it is not different from the two-case storage case.

  FIG. 1 shows an embodiment of a disc-shaped recording medium storage case according to the present invention. Reference numeral 1 denotes a main body, 2 denotes a lid, the main body 1 has a box shape having a base-side widest surface, and the lid 2 has a cover-side widest surface. The lid 2 is connected to the main body 1 through the connecting portion 3 and meshes with the connecting portions 4, 4... Provided on the edges of the main body 1 and the lid 2, and the connecting portions 4, 4. By inserting the shaft pins 5 and 5 into the shaft hole, the lid 2 can be opened and closed, and the main body 1 can be covered.

  In this figure, the lid 2 is assembled as a storage case by inserting the shaft pins 5 and 5 through the connecting portions 4, 4. Since the boundary between the main body 1 and the lid 2 is thinned, the connecting portion 3 is bent and bites the connecting portions 4, 4 provided on the lid 2 with the connecting portions 4, 4. The shaft pins 5 and 5 are inserted through the shaft holes. Therefore, the lid 2 can be opened and closed with respect to the main body 1 through the shaft pins 5 and 5 of the connecting portions 4, 4.

  A holding portion 7 is provided at the center of the base surface 6 of the main body 1, and a holding portion 9 is also provided on the base surface 8 of the lid 2. The holding part 7 of the main body 1 and the holding part 9 of the lid 2 are provided so as to protrude from the base surfaces 6, 7, and the shapes of the holding parts 7, 9 are substantially oval, and their directions cross each other in the vertical direction doing.

  In FIG. 2, disks 10 and 10 serving as disk-shaped recording media are attached to holding parts 7 and 9 on the main body 1 and the lid 2. That is, it is a case where two discs 10 and 10 are stored. FIG. 3 shows a case for storing one disk 10 in the main body 1 and for one sheet in which the disk 10 is not stored in the lid 2. A ring-shaped cover 11 is attached to the holding portion 9 of the lid 2 so that the disk 10 cannot be attached.

  FIG. 4 shows a case where the disk 10 is attached to the holding part 9 of the lid 2. The ring-shaped cover 11 is fitted to the holding part 7 of the main body 1 so that the disk 10 cannot be attached. Here, the structure and form of the holding portions 7 and 9 to which the disk 10 is attached are not limited, and FIG. 5 shows a specific example thereof.

  This figure is an enlarged view of the holding portions 7 and 9 provided on the main body base surface 6 and the lid base surface 8, but arms 13 a and 13 b are formed on the mounting surface 12 of the holding portions 7 and 9. The surface 12 is separated by slit grooves 14 and 14, and approximately semi-cylindrical engaging convex portions 15a and 15b project from the arm tip. Therefore, the coupling 16 is interposed between the engaging convex portions 15a and 15b so as to be contracted. However, the engaging convex portions 15a and 15b are combined with each other to form a column with a low height. To engage and engage. Here, if the engaging convex portions 15a and 15b are pressed from above, the arms 13a and 13b are bent, and the thin joint 16 is curved and deformed, so that the engaging convex portions 15a and 15b contract. I can do it.

  Since the arms 13a and 13b are separated from the mounting surface 12 by the slit grooves 14 and 14, the arms 13a and 13b can be bent and deformed by pressing the engaging convex portions 15a and 15b. The arms 13a and 13b are provided at positions protruding slightly upward from the base surfaces 6 and 8 so that the arms 13a and 13b can be bent and deformed. Then, engagement claws 17a and 17b separated from the arms 13a and 13b through another slit groove are provided, and the engagement claws 17a and 17b make a pair with the engagement convex portions 15a and 15b.

  That is, the engagement claws 17a and 17b stand up at a position where a part of the engagement convex portions 15a and 15b of the substantially semi-cylindrical shape is cut out. Moreover, the tips of the engagement claws 17a and 17b stand slightly higher than the engagement protrusions 15a and 15b. Therefore, the disc 10 is placed on the placement surface 12 of the holding portions 7 and 9, and the engaging convex portions 15 a and 15 b and the engaging claws 17 a and 17 b are fitted into the central hole of the disc 10 and engaged. The engagement claws 17a and 17b are engaged with the inner peripheral edge of the central hole.

  The disc 10 is placed on the mounting surface 12 of the holding portions 7 and 9 so that the engaging claws 17a and 17b fit into the central holes. The engaging convex portions 15a and 15b and the engaging claws 17a and 17b are located at the center of the disc 10. As a result, the arms 13a and 13b are bent and deformed. And engagement convex part 15a, 15b and engagement nail | claw 17a, 17b can shrink | contract and can fit in a center hole. Since the deformable joint 16 is interposed between the engaging projections 15a and 15b, the engaging projections 15a and 17b can be contracted and fitted into the central hole, and the engaging claws 17a and 17b are bent and deformed toward the center.

  Engaging projections 15a and 15b fitted in the central hole expand once after the arms 13a and 13b return to their original positions and then fit into the central hole. Then, the engagement claws 17a and 17 are engaged with the inner peripheral edge of the central hole. As described above, the arms 13a and 13b are bent and deformed, so that they can be attached to the holding portions 7 and 9 without exerting excessive force on the disk 10.

  On the contrary, when the disk 10 is removed from the holding portions 7 and 9, the engaging convex portions 15a and 15b are pressed from above. If pressed, the arms 13a and 13b are bent and deformed, and the engaging protrusions 15a and 15b and the engaging claws 17a and 17b contract and come out of the center hole. In this case, the disk 10 is placed on the mounting surface 12, and even if the engaging protrusions 15a and 15b are pressed, the central part of the disk 10 does not bend forcibly.

  Once the engaging projections 15a and 15b and the engaging claws 17a and 17b contract and come out of the central hole of the disk 10, the disk 10 can be easily removed without fitting into the central hole again. . On the other hand, when the disk 10 mounted on the holding portions 7 and 9 is removed, not only can the engaging projections 15a and 15b be pressed, but also the outer periphery can be picked and pulled up. That is, the engagement claws 17a and 17b that can be easily bent are disengaged from the inner peripheral edge of the central hole, so that the disk 10 can be removed.

  FIG. 5B shows a case where the ring-shaped cover 11 is fitted to the engaging projections 15a and 15b of the holding portions 7 and 9, and FIG. 5C shows the ring-shaped cover 11. The ring-shaped cover 11 has an L-shaped cross section and is easily engaged with the engagement claws 17a and 17b. The operation for fitting the ring-shaped cover 11 to the engaging projections 15a and 15b is the same as that for attaching the disk 10, and the operation for removing it is the same.

  Thus, if the ring-shaped cover 11 is fitted to the engaging convex portions 15a and 15b, the disk 10 cannot be attached. However, the cover that prevents the disk 10 from being attached to the engaging projections 15a and 15b is not limited to the ring-shaped cover 11, and the U-shaped cover 18 shown in FIG. Can be attached to.

  FIG. 6A shows the form of the holding portions 7 and 9, and FIG. 6B shows the case where the U-shaped cover 18 is attached to the holding portions 7 and 9. Here, the basic structure of the holding portions 7 and 9 is the same as that in the case of FIG. 5A, but the mounting surfaces 12 and 12 are extended to both sides to provide L-type engaging portions 19 and 19, and the base Engagement holes 20 and 20 are formed between the surfaces 6 and 8. A state where the U-shaped cover 18 is attached to the holding portions 7 and 9 is shown in FIG.

  The U-shaped cover 18 has two arms 21 and 21, and the arm base is provided with a covering plate 22. The arms 21 and 21 are fitted into the engaging holes 20 and 20 of the holding portions 7 and 9 and covered. The plate 22 covers one arm 13a. Small claws 23 and 23 project from the end of the arm, and the claws 23 and 23 are locked to the L-shaped engaging portions 19 and 19 so as not to be detached. Thus, by attaching the U-shaped cover 18, the arm 13 a is covered with the covering plate 22, and as a result, the disk 10 is not attached to the engaging convex portions 15 a and 15 b.

  FIG. 7 is an embodiment showing a storage case in which the U-shaped cover 18 shown in FIG. 6C is attached to the holding portion 9 provided on the lid 2. Although the disk 10 is attached to the holding part 7 of the main body 1, the disk 10 cannot be attached to the lid side by attaching the U-shaped cover 18 to the holding part 9 of the lid 2. As described above, the cover may be a ring-shaped cover or a U-shaped cover, but may be any other form as long as the disk cannot be attached to the holding portion.

  FIG. 8 shows another embodiment of the storage case according to the present invention. Although the basic structure is the same as in the case of FIG. 1, the holding portion 9 provided on the lid 2 has a detachable structure. When used as a storage case for one sheet, the holding portion 9 9 can be removed. That is, mounting guides 24, 24 are provided on the base surface 8 of the lid 2, and the holding portion 9 is fitted and attached to the mounting guides 24, 24.
