Description

[Detailed description of the invention] [Industrial application field] Conventionally, disk cartridges, which are represented by floppy disks, generally have a jacket enclosing a magnetic disk made of a relatively flexible plastic sheet, and an envelope made of non-woven fabric. However, recently, a hard case has been proposed for this type of disk cartridge in which the jacket is a hard case.

Although this invention is not necessarily limited to such a hard case type, it relates to a storage box suitable for individually storing flat disk cartridges of this type.

[Conventional technology]

As a conventionally known technique, there is no dedicated storage box for individually storing this type of hard case type disk cartridge.

Of course, a storage box for a Philips-type magnetic tape cassette is provided with a box body and a lid pivotally connected to the box body so as to be rotatable in opening and closing.
For example, there is a type of box in which the tape cassette is inserted into the lid and installed, and then the lid is closed to the box body to seal the tape cassette.
It is known from the publication No. 12415. In order to prevent the tape cassette from moving back and forth and from side to side and falling off when the tape cassette is inserted into the lid from above and is held on the bottom wall of the lid, Front and rear side walls and left and right side walls are erected. In addition, a slot is provided at the upper end of one side wall of the lid to guide the insertion of the tape cassette into the lid, and one of the existing protrusions on the left and right outer surfaces of the tape cassette is guided into the slot. It takes a form.

[Problem that the invention attempts to solve]

However, in the storage box seen in the conventional example mentioned above,
The slot provided in one side wall of the lid is only for guiding the tape cassette when it is inserted into and removed from the lid. When the tape cassette is attached to the lid, the opposing side walls provided on the lid prevent the tape cassette from falling off in the thickness direction. In this way, in the thickness direction of the tape cassette, if the lid is provided with two side walls for holding the tape cassette, the overall thickness of the storage box will increase.

However, the disk cartridges to which the present invention is directed are used in large numbers, and the thicker each storage box is, the more extra storage space is required. Therefore, the above-mentioned conventional form cannot be adopted as a storage box for the disk cartridge. It is necessary to improve the means for holding the disk cartridge to the lid.

[Purpose of invention]

The present invention has been proposed in order to eliminate such conventional problems.

An object of the present invention is to reduce the thickness of a storage box for storing flat disk cartridges as much as possible.

The object of the present invention is to provide a storage box in which a disk cartridge can be easily inserted and removed, can be held securely, and can prevent rattling of the disk cartridge as much as possible in the stored state.

[Means for solving problems]

The object of the present invention is a flat disk cartridge A in which a disk 2 is rotatably mounted on a disk case 1, and guide grooves 20, 20 are formed on the left and right outer surfaces 18, 18 of the disk case 1.

The storage box of the present invention has a box body 36 whose top surface is open.
and a lid 37 that closes the opening top surface of the box body 36 so as to be openable and closable, and has a basic form in which the rear end of the lid 37 is pivotally supported on the rear end side of the box body 36 so as to be rotatable in opening and closing. . In addition, in the present invention, the lid body 37 has left and right side pieces 46, 46, and a rear wall 47 at the rear end, and the guide grooves 20, 20 are slidably fitted into the left and right side pieces 46, 46. Part 49, 49
was formed.

[Effect]

In such a case, open the box body 36 as shown in Figure 6.
Then, by rotating the lid 37 upward and sliding the disk cartridge A along the inner surface of the lid 37 while being guided by the left and right side pieces 46, 46, the left and right sides of the disk cartridge A can be moved. Guide groove 2
0 and 20 fit into protrusions 49 and 49 provided on the left and right pieces 46 and 46 of the lid body 37, respectively. The insertion end of the disk cartridge A is connected to the rear wall 47 of the lid body 37.
It was accepted, and now disk cartridge A
is held on the inner surface of the lid body 37. Next, box body 3
When the lid 37 is closed at 6, the disk cartridge A is stored in a sandwiched state between the box body 36 and the lid 37.

Conversely, when taking out the disk cartridge A from the storage box, when the lid 37 is rotated upward from the box body 36, the entire disk cartridge A held on the inner surface of the lid 37 is exposed, so that the lid can be removed. The disk cartridge A can be easily extracted from the body 37.

[Effect of idea]

According to the present invention as described above, by guiding the disk cartridge A along the inner surface of the lid body 37, the disk cartridge A can be easily inserted into and removed from the lid body 37.

Moreover, when the disk cartridge A is completely inserted into the lid 37, the left and right guide grooves 20, 20 on the side of the disk cartridge A automatically fit into the left and right protrusions 49, 49 of the lid 37. , the insertion end of the disk cartridge A is the lid body 37.
It is received by the rear wall 47 of. Therefore, the pair of left and right protrusions 49, 49 provided on the lid 37 and the rear wall 47 allow the disk cartridge A to be attached to the lid 37.
It is possible to securely hold and temporarily fix the material by preventing it from falling off in the vertical and horizontal directions. Furthermore, when the lid body 37 is closed to the box body 36 side from this state, both 3
6 and 37, the disk cartridge A can be held in a pinched state, and the wobbling of the disk cartridge A in the stored state can be prevented as much as possible.

In particular, the lower surface of the lid body 37 may remain open, and there is no need to provide a wall member here to prevent the disk cartridge A from dropping downward. Therefore, the overall thickness of the storage box can be reduced by eliminating the need for this extra wall member, which means that when a large number of disk cartridges A are stored in each storage box and arranged side by side, the storage space is saved. This means that it can be made smaller, which is extremely significant.

Further, if the guide grooves 20, 20 are configured such that one end thereof, for example, the front side of the disk cartridge (the side where the magnetic head insertion window 4 is present) is open as shown in the illustrated example, and the rear side is closed, It is now possible to give direction when installing the disk cartridge A to the lid 37, and since the magnetic head insertion window 4 is always located on the rear side of the lid 37, it is easy to use your fingers when removing the disk cartridge A. Contact with the magnetic head insertion window 4 can also be effectively prevented.
