DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage case for storing a disk cartridge represented by a magneto-optical disk such as an MD or MO.

[0002]

2. Description of the Related Art Various types of storage cases for floppy disks (named 3.5 inches) are commercially available as storage cases of this kind. One of the storage cases is composed of a case main body having an entrance opening on the upper surface, and a lid pivotally supported by the case main body so as to be swingably openable and closable.
Several partition members are provided inside the case main body to support each floppy disk in a posture inclined obliquely backward. According to this, the floppy disk housed in the case is
It is supported diagonally while leaning against the partition, so even if a large number of floppy disks are accommodated in a state of being stacked back and forth, it is easy to identify individual floppy disks and take them out of the case. ing.

[0003]

As described above, the storage case for accommodating the disk cartridges in a state inclined in the thickness direction is suitable for selecting each cartridge and taking out one by one. Is inclined in one direction, so that the number of disk cartridges that can be accommodated for the size of the storage case is small.

In order to increase the number of disk cartridges to be accommodated, it is most effective and wasteful to arrange the cartridges side by side in a vertical standing posture. However, since the thickness of the disk cartridge is small, it is difficult to remove only one of the rows out of the row when a large number of disk cartridges are stored in a side-by-side configuration. troublesome.
When the number of disk cartridges accommodated in the case is small, there is also a disadvantage that each cartridge cannot stand up and falls to the bottom of the case.

An object of the present invention is to store more disk cartridges side by side in a substantially vertical standing posture,
In addition, it is an object of the present invention to provide a storage case in which a target disk cartridge can be easily taken out of a case from a group of disk cartridges. Another object of the present invention is to allow a group of disk cartridges to be lifted above the bottom wall of the case with the lid open, and to lift the adjacent disk cartridges stepwise so that each disk cartridge can be easily moved out of the case. To provide a storage case that can be taken out of the storage case.

[0006]

The storage case of the present invention comprises:
A box-shaped case body 10 for accommodating a plurality of disk cartridges M side by side in a standing posture;
1 that covers the upper and lower surfaces of the door to open and close the doorway 11
2 is provided. The lid 12 is the entrance 1 of the case body 10.
1 is supported so that it can swing open and close about a shaft 23 provided near the lower front part of the front. Push-up wall 22 facing the majority front portion of the bottom surface of disk cartridge M housed in case body 10
Are formed to extend rearward at the bottom of the lid 12. With the lid 12 opened to the open position and the entrance 11 opened, the disc cartridge M is pushed up by the wall 22.
Thus, the push-up operation can be performed above the bottom wall 15 of the case body 10. The disc cartridge M when pushed up may be in a forwardly inclined position as shown in FIG. 1 or in a position substantially parallel to the accommodation position as shown in FIG.

More specifically, as shown in FIG. 2, a plurality of partition walls 17 for holding the disk cartridge M in an upright posture are protruded inside the case body 10. The partition walls 17 extending in the front-rear direction can be arranged at regular intervals in the left-right direction so that one disk cartridge M can be fitted between adjacent partition walls 17 one by one. The front-rear length (rear projecting length) of the push-up wall 22 is set to be different in the left-right width direction. Specifically, the front-rear length of the push-up wall 22 is gradually increased from one side in the left-right width direction to the other side.

As shown in FIG. 4, for example, the case body 10 includes a pair of left and right side walls 13 and a rear wall 14 connecting the both side walls 13.
And a bottom wall 15, and a front regulation wall 35, which is provided between the side walls 13 and cooperates with the rear wall 14 to regulate the back and forth movement of the disk cartridge M.
Thus, in the state where the lid 12 is fully opened, the disk cartridge M can be lifted up by the push-up wall 22 almost in parallel with the storage posture.

[0009]

When the door 12 is opened by opening the lid 12, the bottom surface of the disk cartridge M is
2 can be lifted above the bottom wall 15 by the lifting operation at the rear end of the push-up wall 22 provided on the disk drive 2. Can be easily taken out. Since the disk cartridge M is housed in the case body 10 in the upright posture in the left and right side-by-side shape, compared with the storage case that accommodates the disk cartridge in the inclined posture arranged front and rear,
More disk cartridges M can be accommodated in the case.

A plurality of partition walls 17 are provided inside the case body 10.
When the disk cartridge M is protruded, the disk cartridge M can be held almost vertically and can be prevented from falling down to the bottom of the case even when a small number of disk cartridges M are accommodated in the case. If the front and rear lengths of the push-up wall 22 are set to be different from each other in the width direction, the push-up height of the adjacent disk cartridges M changes. It is possible to avoid taking over the M as much as possible and to further facilitate its removal. If the front-rear length of the push-up wall 22 is gradually increased from one side to the other side, the front portions of the adjacent group of disk cartridges M can be projected stepwise as shown in FIG.

As shown in FIGS. 4 to 6, according to the storage case provided with a front regulation wall 35 for regulating the front and rear movement of the disk cartridge M in front of the case in cooperation with the rear wall 14, the push-up wall 22 is used. Since the disk cartridge M to be moved up and down can be slid while being restricted by the front regulation wall 35 and the rear wall 14 while being tilted, the disc cartridge M can be lifted substantially in parallel with the posture at the time of storage.

The front edge of the wall 15 is joined or closely opposed.

(Embodiment 2) FIGS. 4 to 6 show another embodiment of the storage case. Case body 1 in this embodiment
0 has a pair of left and right side walls 13 and a rear wall 14 and a bottom wall 15 connecting the side walls 13 as shown in FIG. 6, and connects the side walls 13 to an upper half near the front edges of the side walls 13. The front regulation wall 35 is provided, and the opening on the upper surface side is the entrance 11. The front-rear distance between the front regulation wall 35 and the rear wall 14 is set slightly larger than the front-rear dimension of the disk cartridge M. The vertical height of the side walls 13 is set smaller than the vertical height of the disk cartridge M. Therefore, the upper part of the disk cartridge M housed in the case is located at the entrance 11
(See FIG. 5). However, the vertical height of the rear wall 14 is set slightly larger than the vertical height of the disk cartridge M. The partition wall 17 protrudes from the inner surface of the rear wall 14 and the inner surface of the front regulation wall 35 so as to face each other.

The lid 12 is connected to the upper wall 19 covering the upper part of the entrance 11 of the case body 10, the front wall 20 covering the front outer surface of the front regulation wall 35, and the side wall 13 of the case main body 10. And a side wall 21 covering the upper side surfaces, and similarly to the first embodiment, a push-up wall 22 is protruded rearward from the lower end of the front wall 20, and the rear edge is directed from one side to the other side. It is gradually increasing. At the inner corners of the upper wall 19 and the front wall 20, ribs 36 also serving as reinforcing members are provided so as to correspond to the positions where the partition walls 17 are provided. The rib 36 also functions as a partition wall.

In a state where the lid 12 is closed and the entrance 11 is closed, the disk cartridges M are held upright in the left and right side. In addition, the joining wall 21a provided on the side wall 21 of the lid 12 enters the upper edge inner surface and the front edge inner surface of the side wall 13 of the case main body 10, respectively, and regulates the lid 12 from shifting in the left-right direction.

When the lid 12 is opened 90 degrees from the above-mentioned lid closed position as shown in FIG. 4, the push-up wall 22 swings upward to push up the disk cartridge M housed in the case. By this push-up operation, the disk cartridge M tends to tilt upward and forward.
However, the front surface is received by the front regulation wall 35 and tilting is regulated. Therefore, the disk cartridge M is lifted up in a slightly upwardly inclined position. That is,
It is lifted almost parallel to the posture at the time of storage, and the entire bottom surface is lifted above the bottom wall 15. Further, along the inclination of the rear edge of the push-up wall 22, the adjacent disk cartridge M
The upper part protrudes stepwise. Therefore, the individual disk cartridge M can be easily taken out.

In the above embodiment, the group of disk cartridges M is pushed up by the push-up wall 22 in a linear stepwise manner. For example, as shown in FIG.
By alternately providing the protrusions 31 and the recesses 32 on the rear edge of the disk cartridge M, the adjacent disk cartridges M may be made to protrude in an uneven manner with the lid 12 opened. FIG.
In this embodiment, a partition wall 17 is provided on the inner surface of the rear wall 14 of the case body 10 so as to protrude forward. The other parts are the same as those of the previous embodiment, and the same members are denoted by the same reference numerals and description thereof will be omitted.

In addition to the above, the shaft 23 may be provided on the side wall 21 of the lid 12 and the bearing hole 24 may be provided on the case body 10 side. A configuration in which several disk cartridges M are stored between the partition walls 17 adjacent to each other on the left and right may be employed. FIG.
The convex portion 31 and concave portion 32 can have their left and right widths expanded so that two or three disk cartridges M can be simultaneously pushed up. The planar shape of the rear edge of the push-up wall 22 when viewed from above may be a curved shape such as a protruding arc or a concave arc. When the number of accommodated disk cartridges M is small, the front-rear length of the push-up wall 22 can be made constant in the width direction.
