Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a storage case for storing disk cartridges typified by magneto-optical disks such as MD and MO.
[0002]
[Prior art]
Various types of storage cases are commercially available for floppy disks (named 3.5 inches). One of the storage cases is composed of a case main body with an entrance opening on the upper surface and a lid that is pivotally supported by the case main body so as to swing open / close. Several partitions are provided to support the disc in an obliquely inclined posture. According to this, the floppy disk accommodated in the case is supported obliquely in a state leaning against the partition, and therefore even if a large number of floppy disks are accommodated in a state where they overlap each other, It can be easily discriminated and taken out of the case.
[0003]
[Problems to be solved by the invention]
As described above, the storage case that accommodates the disk cartridges in a state of being inclined in the thickness direction is suitable for selecting each cartridge and taking out one cartridge at a time, but since all the accommodated cartridges are inclined in one direction. The number of disc cartridges that can be accommodated for the size of the storage case is small.
[0004]
In order to increase the number of disc cartridges accommodated, it is most effective and wasteful to arrange the cartridges in a vertical standing posture in a side-by-side arrangement. However, since the thickness of the disk cartridge is small, it is difficult to pull out only one disk from the storage case when multiple disk cartridges are stored side by side. troublesome. When the number of disk cartridges accommodated in the case is small, there is a disadvantage that each cartridge cannot stand and falls to the case bottom.
[0005]
An object of the present invention is to store a larger number of disk cartridges in a left-right side-by-side configuration with a substantially vertical standing posture, and from the group of disk cartridges, the target disk cartridge can be easily taken out of the case one by one. Is to provide.
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 individual disk cartridges out of the case by lifting the adjacent disk cartridges in a stepped manner. It is to provide a storage case that can be taken out.
[0006]
[Means for Solving the Problems]
The storage case of the present invention includes a box-shaped case main body 10 that accommodates a plurality of disc cartridges M in an upright posture and a lid 12 that covers the upper surface and the front surface of the case main body 10 and opens and closes the doorway 11. I have. The lid 12 is supported so as to be swingable and openable about a shaft 23 provided near the lower part of the front surface of the entrance 11 of the case body 10. A push-up wall 22 facing the majority front part of the bottom surface of the disk cartridge M accommodated in the case body 10 is formed to extend rearward on the bottom part of the lid 12. Thus, the disk cartridge M can be pushed up above the bottom wall 15 of the case body 10 by the push-up wall 22 in a state where the lid 12 is opened to the open position and the doorway 11 is opened. The posture of the disk cartridge M at the time of pushing up may be a forwardly inclined posture as shown in FIG. 1 or a substantially parallel posture as shown in FIG.
[0007]
Specifically, as shown in FIG. 2, a plurality of partition walls 17 that hold the disc cartridge M in an upright posture are provided 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 the disk cartridges M can be fitted one by one between the adjacent partition walls 17. The front-rear length (rear protrusion length) of the push-up wall 22 is set so as to be different in size in the left-right width direction. Specifically, the longitudinal length of the push-up wall 22 is gradually increased from one side to the other side in the left-right width direction.
[0008]
For example, as shown in FIG. 4, the case body 10 is constructed between a pair of left and right side walls 13, a rear wall 14 and a bottom wall 15 that connect both side walls 13, and both side walls 13 to allow the disk cartridge M to move forward and backward. A front regulating wall 35 that regulates in cooperation with the rear wall 14 may be provided. Thus, the disk cartridge M can be lifted by the push-up wall 22 substantially in parallel with the storage posture in a state where the lid 12 is fully opened.
[0009]
[Action]
In a state in which the lid 12 is opened and the doorway 11 is opened, the bottom surface of the disk cartridge M can be lifted at the rear end of the push-up wall 22 provided on the lid 12 and floated above the bottom wall 15. The disk cartridge M can be easily taken out of the case while being put on the upper or lower surface of the individual disk cartridge M and shifted out of the row. Since the disc cartridge M is accommodated in a side-by-side configuration in a standing posture inside the case body 10, a larger number of disc cartridges M are accommodated in the case than a storage case that accommodates the disc cartridge in an inclined posture arranged in front and back. it can.
[0010]
When a plurality of partition walls 17 project from the inside of the case body 10, the disk cartridge M is held upright almost vertically, and even when a small number of disk cartridges M are accommodated in the case, the disk cartridge M moves toward the bottom of the case. It can prevent falling down. When the longitudinal length of the push-up wall 22 is set to be different in the left-right width direction, the push-up height of the adjacent disk cartridge M changes, so that when the disk cartridge M is taken out and operated, the fingertip is adjacent to the adjacent disk cartridge. Taking out M as much as possible is avoided as much as possible. If the longitudinal length of the push-up wall 22 is gradually increased from one side to the other side, the front portions of a group of adjacent disk cartridges M can be projected stepwise as shown in FIG.
[0011]
As shown in FIGS. 4 to 6, according to the storage case provided with the front regulating wall 35 for regulating the back and forth movement of the disk cartridge M in cooperation with the rear wall 14 on the front surface of the case, the raising and lowering operation is performed by the push-up wall 22. The disc cartridge M can be slidably guided while being restricted by the front restricting wall 35 and the rear wall 14, so that the disc cartridge M can be lifted and operated almost parallel to the posture at the time of accommodation.

In FIG. 1, a disk cartridge M accommodates a disk 2 in a thin rectangular box-shaped main body case 1, and a pickup window 3 opened on both the front and back surfaces of the main body case 1 can be slid by a shutter 4. A drive shaft insertion hole 5 is opened at the center of the back surface of the case, and a hub 6 for rotating the disk 2 is disposed so as to face the hole 5. As shown in FIG. 3, the case peripheral wall is provided with a shallow recess for attaching the label 7 and a protect notch 8 for preventing erroneous erasure.
[0013]
The storage case is composed of a box-shaped case main body 10 and a lid 12 that swings and opens the entrance / exit 11 of the case main body 10. In the illustrated example, ten disk cartridges M are placed in an upright position inside the case main body 10. It can be accommodated in a side-by-side configuration.
[0014]
In FIG. 2, the case body 10 is made of a transparent plastic molded product in which a pair of left and right side walls 13 and a rear wall 14 and a bottom wall 15 that connect the side walls 13 are integrally formed. As open. On the upper surface of the bottom wall 15, a large number of partition walls 17 that stand upright and hold the respective disk cartridges M vertically are provided in parallel with the side walls 13 at regular intervals. The front-rear inner dimension and the upper-lower inner dimension of the case body 10 are set slightly larger than the front-rear dimension and the upper-lower dimension of the disc cartridge M, respectively. Accordingly, the disc cartridge M can be moved in the front-rear direction and the up-down direction in a state where the disc cartridge M is accommodated in the case main body 10 in a left-right parallel manner.
[0015]
The lid 12 is formed integrally with the upper wall 19 and the front wall 20 that block the entrance / exit 11 of the case body 10, a pair of left and right side walls 21, and the lower ends of the front wall 20 and both side walls 21 so as to extend integrally to the rear of the case. It consists of a transparent plastic molded product integrally formed with the push-up wall 22. The distance between the left and right outer surfaces of the side walls 21 is set slightly smaller than the distance between the left and right inner surfaces of the side walls 13 of the case body 10. In order to support the lid 12 so as to be swingable and openable, shafts 23 project from the lower sides of the front surfaces of the side walls 13 of the case body 10 so as to face each other, and the shafts 23 pass through the side walls 21 of the lid 12. The bearing hole 24 is pivotally supported. In a state where the lid 12 is closed, the upper wall 19 and the front wall 20 close the entrance 11 and cooperate with the case main body 10 to define a rectangular parallelepiped accommodation space.
[0016]
The lid 12 can be opened 90 degrees around the shaft 23 from the closed position. In order to define the opening limit, a circular recess 25 is formed on the inner surface of each side wall 13 of the case body 10. Further, a circular protrusion 26 is formed on the outer surface of each side wall 21 of the lid 12 so as to fall into the recess 25 and engage therewith. Finger hooks 27 and 28 are provided on the outer upper surface of the upper wall 19 of the lid 12 and the outer surfaces of the side walls 13 of the case body 10 as slip stoppers when the lid 12 is opened.
[0017]
Using the opening operation of the lid 12, the disk cartridge M accommodated in the case is lifted up to the front upward inclined posture above the bottom wall 15, and the push is applied to the bottom of the lid 12 in order to facilitate its removal. A raising wall 22 is provided. The push-up wall 22 protrudes rearward so as to be flush with the bottom wall 15 of the case body 10 when the lid 12 is closed, and the upper surface thereof faces the front portion of the bottom surface of the disk cartridge M. ing. That is, in the accommodated state where the lid 12 is closed, the internal disk cartridge M is in a state where the front end of the lower end straddles the upper surface of the push-up wall 22.
[0018]
The longitudinal length of the push-up wall 22 is increased from one side to the other side in the left-right direction, and the rear edge is inclined in a plan view in the closed state. As a result, when the disk cartridge M is pushed up as shown in FIG. 3, the upper surface of the adjacent disk cartridge M protrudes from the inlet / outlet 11 in a stepped manner, thereby facilitating the removal of the individual disk cartridge M. . Further, the case peripheral surface on which the label 7 is attached can be inclined obliquely upward so that the label display such as the title and the file name can be easily seen. The bottom wall 15 of the case body 10 is formed with an opening 30 for receiving the push-up wall 22 at the front end, and the rear edge and bottom of the push-up wall 22 in the closed state as shown in FIG. The front end edge of the wall 15 is joined or closely opposed.
[0019]
(Example 2)
4 to 6 show another embodiment of the storage case. As shown in FIG. 6, the case body 10 in this embodiment has a pair of left and right side walls 13, a rear wall 14 and a bottom wall 15 that connect the side walls 13, and the upper half of the side walls 13 near the front edge. A front regulating wall 35 for connecting the side walls 13 to each other is provided, and the opening on the upper surface side is used as the entrance / exit 11. The front-rear distance between the front regulating 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 to be smaller than the vertical height of the disk cartridge M. Accordingly, the upper part of the disk cartridge M housed in the case protrudes from the doorway 11 (see FIG. 5). However, the vertical height of the rear wall 14 is set to be slightly larger than the vertical height of the disk cartridge M. The partition wall 17 protrudes from the rear wall 14 and the inner surface of the front regulating wall 35 in a front-rear facing manner.
[0020]
The lid 12 includes an upper wall 19 covering the upper side of the entrance / exit 11 of the case body 10, a front wall 20 covering the front outer surface of the front restriction wall 35, and both sides above the entrance / exit 11 continuously to the side wall 13 of the case body 10. And a side wall 21 that covers the surface, and as in the first embodiment, a push-up wall 22 protrudes rearward from the lower end of the front wall 20, and the rear edge is gradually increased from one side to the other side. is there. At the inner corners of the upper wall 19 and the front wall 20, ribs 36 that also serve as reinforcements are provided in a protruding manner corresponding to the protruding positions of the partition wall 17. This rib 36 also acts as a partition wall.
[0021]
In a state where the lid 12 is closed and the doorway 11 is closed, the disc cartridge M is held upright in a left-right parallel manner. Moreover, 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 restricts the lid 12 from shifting in the left-right direction.
[0022]
As shown in FIG. 4, when the lid 12 is opened 90 degrees from the lid closed position, the push-up wall 22 swings upward and pushes up the disc cartridge M accommodated in the case. By this push-up operation, the disk cartridge M tends to tilt upward. However, the front surface is received by the front regulating wall 35 and the tilting is regulated. Therefore, the disc cartridge M is lifted in a posture slightly tilted upward. That is, it is lifted substantially parallel to the posture at the time of accommodation, 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 upper part of the adjacent disk cartridge M protrudes in a stepped manner. Accordingly, the individual disk cartridge M can be easily taken out.
[0023]
In the above embodiment, the group of disk cartridges M are pushed up in a linear staircase shape by the push-up wall 22, but, for example, as shown in FIG. By alternately providing the, the adjacent disc cartridge M may be protruded in a concavo-convex shape with the lid 12 open. Further, in the embodiment of FIG. 7, a partition wall 17 is projected forward on the inner surface of the rear wall 14 of the case body 10. Since others are the same as the previous embodiment, the same reference numerals are assigned to the same members, and descriptions thereof are omitted.
[0024]
In addition to the above, the shaft 23 may be provided on the side wall 21 side of the lid 12 and the bearing hole 24 may be provided on the case body 10 side. Several disc cartridges M may be housed between the partition walls 17 and 17 adjacent to the left and right. The left and right widths of the convex portion 31 and the concave portion 32 in FIG. 7 can be increased so that two or three disk cartridges M are simultaneously pushed up. The planar shape when the rear edge of the push-up wall 22 is viewed from above may be a curved shape such as a salient arc shape or a concave arc shape. When the number of stored disc cartridges M is small, the longitudinal length of the push-up wall 22 can be made constant in the width direction.
[0025]
【The invention's effect】
In the present invention, a push-up wall 22 is provided at the bottom of the lid 12, and the bottom front portion of the disc cartridge M in the case is lifted above the bottom wall 15 by the push-up wall 22 in a state where the lid 12 is opened. Therefore, even when a group of disk cartridges M are accommodated in the case in a left-right parallel manner, the target disk cartridge M can be easily removed while being shifted out of the row. Therefore, it is possible to obtain a storage case that can simultaneously satisfy the contradicting requirements of accommodating a larger number of disk cartridges M and easily taking out the target disk cartridge M from the cartridge group in the case. In particular, when the longitudinal lengths of the push-up walls 22 are different from each other in the width direction, the adjacent disk cartridges M can be lifted in a stepwise manner, so that the individual disk cartridges M can be taken out more easily.
