BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mini disk storage case for storing a mini disk having an optical disk-shaped record carrier housed in a casing.

[0002]

2. Description of the Related Art Recently, an information storage device for audio called a mini disk (MD) is about to be put into practical use. As shown in FIG. 11, the mini disc 1 includes an optical disc-shaped record carrier 2 and a rectangular thin casing 3.
It has a structure similar to that of a micro floppy disk. The casing 3 is formed by connecting an upper casing member 4 and a lower casing member 5, and has a concave shutter incorporating portion 6 formed on one side thereof. The shutter incorporating portion 6 has a disc-shaped record carrier. A window hole 7 is formed so as to face 2 and a shutter 8 for opening and closing the window hole 7 is slidably incorporated. A label surface 9 is formed on the surface of the upper casing member 4. The size of the mini disc 1 as described above is about 70 mm in each length and width, which is relatively small.

Of course, the mini disk 1 as described above
For protection, it is desirable to store it in a storage case when storing it. For example, in another floppy disk, which is a disk for storing information, a storage case in which a plastic cover is openably and closably attached to a plastic base is used. However, the storage case consisting of the base and the cover which are separately molded in this way is costly,
In particular, the mini disk 1 having a relatively small size is disadvantageous. Also, since the size of the mini disc 1 is small, it is necessary to particularly consider the ease of storing and taking out the mini disc 1 in the mini disc storage case.

[0004]

As described above, with respect to the mini disk storage case, it is necessary to reduce the cost and increase the ease of taking out the mini disk 1 having a small size.

An object of the present invention is to solve the above problems, and an object thereof is to provide a mini disk storage case which can be manufactured at low cost and from which mini disks can be easily taken out.

[0006]

In order to achieve the above object, the present invention provides a mini disk storage case integrally molded of plastic for storing a mini disk in which a disk-shaped record carrier is stored in a rectangular thin casing. A base and a cover rotatably and unrotatably connected to the base integrally with each other, and a mini disk is detachably accommodated in a surface of the base facing the cover in parallel with the facing surface. And a rib that is formed on the facing surface and that surrounds and holds the edge of the mini disk. A part of this rib is separated from the edge of the mini disk. As the curved portion that is curved to the inside, the inside of this curved portion is used as the finger insertion portion.

[0007]

In the mini disk storage case of the present invention, when storing the mini disk, the base and the cover are opened, and the mini disk is stored in the storage portion of the base opposite to the cover, and then the base and the cover are Close. In this housed state, the mini disk is positioned parallel to the facing surface, and ribs projectingly formed on the facing surface surround and hold the edges of the mini disk, and the housing portion is covered by the cover. On the other hand, when taking out the mini disc, after opening the base and cover, put your fingers in the finger rest inside the curved part where a part of the rib curves away from the edge of the mini disc. Put your finger on the edge of the mini disc and take out the mini disc from the storage compartment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the mini disk storage case of the present invention will be described below with reference to FIGS.
The mini-disc storage case 11 is integrally molded of plastic having a certain elasticity, and a pair of left and right rectangular plate-shaped bases 12 also serving as covers are rotatably openable and closable via a back plate portion 13. It is one that is connected together. That is, the back plate portion 13 integrally connects the long sides of both bases 12, and the rotatable thin hinge portions 14 are formed along both longitudinal edges of the back plate portion 13. ing. Then, on the opposing surfaces of both bases 12 when these are closed, outer peripheral ribs 15 having a substantially U-shape in a front view are formed to project along the edges excluding the thin hinge portion 14, and the outer peripheries thereof are formed. A partition rib 16 is formed so as to project from the center of the rib 15 toward the thin hinge portion 14. Further, a pressing rib 17 along the long side of the base 12 is projectingly formed in the central portion on the side of the thin hinge portion 14 on both of the facing surfaces, and from the central portion of the pressing rib 17 toward the partition rib 16. Partition ribs 18 are formed so as to project. Further, the outer peripheral ribs 15 are provided on the opposite surfaces.
Pressing ribs 19 projecting from the inner surfaces of both ends of the pressing ribs and located on the extension lines of the pressing ribs 17 are formed so as to project. In this way, half of the outer peripheral ribs 15, partition ribs 16 and 18 and pressing ribs
A storage unit 20 is formed between the storage units 17 and 19 in which the mini disc 1 is detachably fitted and stored. More specifically, the ribs 15,
16, 18, 17 and 19 surround and hold the peripheral edge of the mini disk 1, and the mini disk 1 is positioned parallel to the base 12. Then, the storage unit 20 includes the bases 12
There are two in each, and there are a total of four in the storage case 11. Further, on the inner surfaces of the outer peripheral rib 15 and the pressing rib 17, pressing claw portions 21 and 22 for pressing the mini disk 1 into the storage portion 20 are formed at positions near both sides of the partition ribs 16 and 18, respectively. The pressing claws 21 and 22 have a triangular shape that is pointed toward the opening side of the storage section 20. Further, each storage portion 20 is provided on the long side portion of the outer peripheral rib 15.
On the other hand, a curved portion 23 that is curved in an arc shape is formed toward the side away from the edge of the mini disk 1 stored here, and the inside of this curved portion 23, that is, the curved portion 23 and the stored mini-disk 23 are formed. A finger inserting portion 24 is formed between the disc 1 and the edge thereof. With this, the base 12 has
Thin hinge portions 25 are formed symmetrically with respect to 23. Further, the opposing surfaces of the bases 12 are respectively located outside the central portion of the outer peripheral rib 15, and are engaged with each other in a detachable manner to hold the bases 12 in a closed state. 27 is formed to project. The clamp claws 26 and 27 and the outer peripheral rib 15 are integrally connected by a reinforcing rib 28.

Next, the operation of the above configuration will be described. When the mini disk 1 is stored in the storage case 11, first, both bases 12 are rotated and opened in the thin hinge portion 14. At this time, both bases 12 as shown in FIG.
From the closed state, by pushing the clamp claw portion 26 side of the lower one base 12 toward the thin hinge portion 14 in the figure, elastic deformation of the storage case 11 itself made of plastic causes both bases 12 to move. The clamp claws 26, 27 can be removed from each other. After opening both the bases 12 in this way, the mini disk 1 is fitted and stored in the vacant desired storage part 20 among the four storage parts 20 in total. In this stored state,
The mini disc 1 is located parallel to the base 12 and has ribs 15 and 1
6, 17, 18, and 19 surround and hold the peripheral edge of the mini disk 1. Along with this, the outer peripheral rib 15 and the pressing rib 17
The holding claw portions 21 and 22 are hooked on both side edge portions of the mini disc 1, so that the mini disc 1 is securely held in the storage portion 20, and the mini disc 1 is prevented from easily falling off. In addition, when the mini disk 1 is fitted into the storage portion 20,
The presser pawls 21 and 22 having an inclined shape are the mini disc 1
As the storage case 11 itself elastically deforms as it is pushed by, the mini disk 1 gets over the pressing claws 21 and 22. Then, after the mini disk 1 is fitted into the storage portion 20, both bases 12 are rotated and closed. Both bases
When closing the 12 ends, clamp claws of these two bases 12
26 and 27 are elastically deformed and engaged with each other, and thereafter, the two bases 12 are surely kept closed by the mutual engagement of the clamp claws 26 and 27. In this state, both bases 12
The ribs 15, 16, 17, 18, 19 of the base 12 abut each other, the opening of the storage portion 20 of the base 12 is closed by the other base 12, and the mini disk 1 is positioned in the closed storage portion 20. .. On the other hand, when taking out the mini disk 1 from the storage case 11, first, both bases 12 are opened. And FIG.
Support the storage case 11 from below with one hand,
The finger F of the other hand is put in the finger insertion portion 24 between the curved portion 23 of the outer peripheral rib 15 and the edge of the mini disc 1, and the finger F is hung on the edge of the mini disc 1 here. At this time, the base 12 is elastically bent so as to warp at the thin hinge portion 25, and the width of the finger inserting portion 24 is expanded, so that the finger F can be easily inserted here. Then, the edge of the mini disk 1 on which the finger F is hung up is lifted and the mini disk 1 is rotated and taken out from the storage section 20. At this time, the holding case 11 itself is elastically deformed, so that the holding claw portion 21 of the outer peripheral rib 15 is disengaged from the mini disc 1, and the end edge portion of the mini disc 1 is located below the holding claw portion 22 of the holding rib 17. Is pulled out.

As described above, according to the configuration of the above-described embodiment, since the entire mini disk storage case 11 is integrally molded of plastic, the cost can be reduced. In addition, a pair of bases 12 are connected so as to be rotatable and openable and closable along their long sides, and a pair of storage portions are respectively attached to both bases 12 along their long sides.
20 is formed, which is the most reasonable in terms of the size of the mini disc 1 of about 70 mm square. That is, the storage case 11 can be easily handled in both the closed state and the open state, and the storage case 11 can be properly stored in a rack or the like, and as many mini discs 1 as possible can be stored in one storage case 11. Can be stored. This also leads to cost reduction. Also, each mini disc 1
Each mini disk 1 can be reliably protected by being stored in the storage section 20 one by one. Furthermore, the curved portion on the outer peripheral rib 15
Since the finger insertion portion 24 is formed between the curved portion 23 and the end edge of the mini disc 1, the mini disc 1 can be easily taken out. Moreover, since the thin hinge portion 25 is formed on the base 12 so as to correspond to each curved portion 23, the curved portion 23 portion of the base 12 can be elastically deformed, and the width of the finger inserting portion 24 can be easily expanded. Disk 1 is even easier to remove.

The present invention is not limited to the above embodiment, and various modifications can be made. For example,
The thin hinge portion 25 is not always necessary. Further, in the above-described embodiment, the pair of bases 12 connected to the long side so as to be rotatable and openable are provided with the pair of storage portions 20 along the long side direction.
However, the number and arrangement of the storage units in the base are not limited to that. For example, it may be a storage case that stores only one mini disk 1. Further, in the above-described embodiment, the base 12 itself also serves as the cover, but with respect to the base having the storage portion for the mini disk 1,
You may provide the cover which does not have a storage part.

[0012]

According to the present invention, the base and the cover are rotatably opened and closed and integrally connected to each other, and the entire mini disk storage case is integrally molded with plastic, so that the cost can be reduced. In addition, since a part of the rib that is formed to project on the base and surrounds and holds the edge of the mini disk is a curved part that is curved away from the edge of the mini disk, and the inside of this curved part is the finger insertion part, You can easily take out the mini disc from the storage part of the base.
