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

[0002]

2. Description of the Related Art Recently, an information storage device for audio called a mini disk (MD) is being put to practical use. As shown in FIG. 11, this mini-disc 1 comprises an optical disc-shaped record carrier 2 and a rectangular thin casing 3.
It has the same structure as a micro floppy disk. The casing 3 is formed by coupling an upper casing member 4 and a lower casing member 5, and has a concave shutter assembly 6 formed on one side thereof. 2, and a shutter 8 for opening and closing the window hole 7 is slidably incorporated therein. A label surface 9 is formed on the surface of the upper casing member 4. The dimensions of the mini-disc 1 as described above are about 70 mm each in the vertical and horizontal directions, and are relatively small.

[0003] Of course, the mini disc 1
Is preferably stored in a storage case during storage for protection. For example, in a micro floppy disk, which is another information storage disk, a storage case in which a plastic cover is pivotally attached to a plastic base so as to be freely opened and closed is used. However, the cost of the storage case including the base and the cover separately formed is high,
In particular, it is disadvantageous for the mini-disc 1 having a relatively small size. In addition, since the size of the mini-disc 1 is small, it is necessary to give special consideration to the mini-disc storage case in terms of ease of storing and taking out the mini-disc 1.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a mini disk storage case according to the present invention will be described below with reference to FIGS.
The mini disk storage case 11 is integrally formed of plastic having a certain degree of elasticity, and a pair of left and right rectangular plate-shaped bases 12 each serving also as a cover are rotatably opened and closed via a back plate portion 13. They are integrally connected. That is, the back plate portion 13 integrally connects one long side of both bases 12, and a rotatable thin hinge portion 14 is formed along each longitudinal side edge of the back plate portion 13. ing. On the opposing surfaces of the bases 12 when they are closed, an outer rib 15 having a substantially U-shape in a front view is formed to protrude along an edge excluding the thin hinge portion 14, respectively. A partition rib 16 protruding from the center of the rib 15 toward the thin hinge portion 14 is formed. A pressing rib 17 along the long side of the base 12 protrudes from a center portion of the thin hinge portion 14 side of the opposing surfaces, and a pressing rib 17 extends from the center portion of the pressing rib 17 toward the partition rib 16. A projecting rib 18 is formed. Further, the outer peripheral rib 15
Pressing ribs 19 protruding from the inner surfaces of both ends of the holding rib 17 and located on an extension of the pressing rib 17 are formed to protrude, respectively.
In this way, a storage portion 20 in which the mini-disc 1 is detachably fitted and stored is formed between the half of the outer peripheral rib 15, the partition ribs 16, 18 and the holding ribs 17, 19, respectively.
More specifically, in the storage section 20, the rib 1
The peripheral edge of the mini-disc 1 is surrounded and held by 5, 16, 18, 17, and 19, and the mini-disc 1 is positioned parallel to the base 12. There are two storage sections 20 in each base 12, and a total of 4
There are two. On the inner surfaces of the outer peripheral rib 15 and the holding rib 17, holding claws 21, 22 for holding the mini-disc 1 into the storage section 20 are formed at positions near both sides of the partition ribs 16, 18. These holding claws 21 and 22 are
It has a triangular shape that is pointed toward the opening side. Further, each of the storage portions 20 is provided at a long side portion of the outer peripheral rib 15.
A curved portion 23 which is curved in an arc shape away from the edge of the mini-disc 1 stored therein is formed inside the curved portion 23, ie, the curved portion 23 and the stored mini-disk. A finger holder 24 is formed between the edge of the disk 1 and the edge. At the same time, the base 12 has
Thin hinge portions 25 are formed symmetrically with respect to each other. Further, on the opposing surfaces of the two bases 12, clamp claws 26, which are located outside the center of the outer peripheral rib 15 and engage with each other in a detachable manner to hold the two bases 12 in a closed state, 27 are protrudingly formed. 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 storing the mini-disc 1 in the storage case 11, first, both bases 12 are rotated and opened at the thin hinge portion 14. At this time, both bases 12 as shown in FIG.
From the closed state, the clamp claw portion 26 side of the one base 12 on the lower side in the figure is pushed toward the thin hinge portion 14, so that the elastic deformation of the plastic storage case 11 itself causes the two bases 12 The clamp claws 26, 27 can be removed from each other. After the two bases 12 are opened in this way, the mini-disc 1 is fitted and stored in an empty desired storage part 20 among the four storage parts 20 in all. In this storage state, the mini-disc 1 is positioned parallel to the base 12 and the rib 1
5, 16, 17, 18, and 19 surround and hold the peripheral edge of the mini-disc 1. At the same time, the holding claw portions 21 and 22 of the outer peripheral rib 15 and the holding rib 17 are hooked on both side edges of the mini-disc 1, so that the mini-disc 1 is securely held in the storage section 20, and Is prevented from falling off. When the mini-disc 1 is fitted into the storage section 20, the storage case 11 itself is elastically deformed as the holding claw portions 21 and 22 having an inclined shape are pressed by the mini-disc 1. 1 is the presser claw 21,
Get over 22. Then, after fitting the mini-disc 1 into the storage section 20, both bases 12 are rotated and closed. When the two bases 12 are completely closed, the clamp claws 26 and 27 of the two bases 12 are engaged with each other while being elastically deformed.
Is securely held closed. In this state, the ribs 15, 16, 17, 18, 19 of both bases 12 abut each other,
The opening of the storage section 20 of the base 12 is closed by the other base 12, and the mini-disc 1 is located in the closed storage section 20. On the other hand, when taking out the mini disk 1 from the storage case 11, the bases 12 are first opened. Then, as shown in FIG. 1, the storage case 11 is supported from below by one hand, and the finger F of the other hand is held in a finger-inserting portion 24 between the curved portion 23 of the outer peripheral rib 15 and the edge of the mini disc 1. Then, a finger F is hung on the edge of the mini disc 1. 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 insertion portion 24 is increased, so that the finger F can be easily inserted here. Then, the user lifts the edge of the mini-disc 1 on which the finger F is hooked, and removes the mini-disc 1 from the storage section 20 by rotating the mini-disc 1. At this time, the holding claw 21 of the outer peripheral rib 15 is disengaged from the mini-disc 1 due to the elastic deformation of the storage case 11 itself, and the edge of the mini-disc 1 is located below the holding claw 22 of the holding rib 17. Is extracted.

As described above, according to the configuration of the above-described embodiment, since the entire mini disk storage case 11 is integrally formed of plastic, the cost can be reduced. In addition, a pair of bases 12 are rotatably opened and closed at their long sides, and a pair of storage portions are respectively connected to both bases 12 along the long side direction.
This 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 is easy to handle in both the closed state and the open state, and the storage case 11 can be appropriately stored in a rack or the like. Can be stored. This leads to cost reduction. Also, each mini disk 1 is 1
Each mini disk 1 can be reliably protected by being stored in the storage section 20 one by one. In addition, the outer rib 15 has a curved portion
Since the finger insertion portion 24 is formed between the curved portion 23 and the 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 in correspondence with each curved portion 23, the curved portion 23 of the base 12 can be elastically deformed, and the width of the finger insertion portion 24 can be easily expanded. The disk 1 is more easily taken out. And, the finger pad 24 is large in design.
Since there is no need to make
Enlargement can be prevented.

Note that the present invention is not limited to the above-described embodiment, and various modifications can be made. For example ,
In the previous SL embodiment, to form a respective pair of the housing part 20 along its longitudinal direction to a pair of base 12 is rotated openably connected at the long sides, the number of housing portion in the base and sequences Is not limited to this. For example, a storage case for storing only one mini disk 1 may be used. Further, in the above-described embodiment, the base 12 itself is also used as a cover. However, a cover having no storage portion may be provided on the base having the storage portion for the mini disc 1.

[0013]

According to the present invention, the base and the cover are rotatably opened and closed and integrally connected, and the entire mini disc storage case is integrally formed of plastic, so that the cost can be reduced. In addition, since a part of the rib formed so as to protrude from the base and surround and hold the edge of the mini-disc is a curved portion curved away from the edge of the mini-disc, and the inside of this curved portion is a finger insertion portion, The mini disk can be easily removed from the storage section of the base.
