DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case device and can be applied to, for example, a case device in which 3.5 inch magneto-optical disks stored in a cartridge are stored one by one.

[0002]

2. Description of the Related Art Conventionally, in a magneto-optical disk device,
Some recording media use a 3.5-inch magneto-optical disc. Such a 3.5-inch magneto-optical disk is housed in a resin cartridge body like a 3.5-inch micro-floppy disk, and can be loaded into and removed from the magneto-optical disk device for each cartridge body. In addition, it is possible to prevent dust from adhering to or scratching the disk surface.

The 3.5-inch magneto-optical disc is housed in a plastic case one by one in a state of being housed in the cartridge body, so that the magneto-optical disc itself is not damaged when being carried or stored. Has been made.

[0004]

However, in the case of a single-package plastic case as described above, the inner wall of the plastic case and the cartridge body come into contact many times due to the vibration when the product is transported as truck cargo or air cargo. Repeatedly, there was a problem that shaving powder was attached to both.

Usually, as shown in FIG. 4, the cartridge body 1 is constituted by storing a magneto-optical disk (not shown) in two halves 1A and 1B. Are the most convex portions 2A.

This is a half 1A of the cartridge body 1,
This is because the outer surface 1B needs to have a gradient of the outer periphery when it is removed from the mold, and it is unavoidable that the parting surface 2 becomes the most convex portion 2A. In addition, in some cases, burrs may protrude from the parting surface 2 during molding.

When vibration is applied as in the case of transportation in such a state, the parting surface 2 of the cartridge body 1 always contacts the inner wall 3A of the plastic case 3,
The projections 2A of the parting surface 2 and burrs at the time of molding are shaved, and as a result, dusting due to shaved powder occurs.

[0008] Such dusting not only impairs the appearance of the product as a magneto-optical disc, but also causes damage to the disc surface if shavings enter the cartridge body 1. Was.

The present invention has been made in view of the above points, and it is an object of the present invention to propose a case device that can prevent the generation of shavings on a parting surface of a cartridge in a state where the cartridge is stored.

[0010]

In order to solve this problem, the present invention provides two injection molded halves 1A,
1B, the cartridge body 1 is housed between the openable and closable upper case 11 and the lower case 13. In the case device 10, the inner wall portion 12A of the upper case 11 and / or the lower case 13 is housed. A relief portion 20 having a concave cross section is provided at a portion facing the mating surface 2 projecting outward from the cartridge body 1 so that the mating surface 2 of the cartridge body 1 does not contact the inner wall portion 12A.

[0011]

When the cartridge body 1 is housed between the upper case 11 and the lower case 13, the outwardly projecting mating surface 2 of the cartridge body 1 is guided into the escape portion 20 so that the cartridge body 1 is Mating surface 2
Can be prevented from contacting the inner wall portion 12A, and thus dusting due to shavings caused by the mating surface 2 of the cartridge body 1 contacting the inner wall portion 12A can be prevented.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.

FIG. 1 in which parts corresponding to those in FIG.
In the figure, reference numeral 10 designates a case device according to the present invention as a whole, after the cartridge body 1 is inserted as shown by an arrow a into a bag portion 12 formed on one side of an upper case 11 made of a substantially square transparent plastic. , Upper case 1
The cartridge body 1 can be housed in the case device 10 by rotating the cartridge body 1 as shown by an arrow b and closing the lower case 13 formed of a square-shaped transparent plastic in accordance with the upper case 11. It has been done.

A pair of projections 14 are integrally formed on the left and right sides of the bag portion 12 of the upper case 11, and the projections 14 are formed in a pair of through holes 15 formed at corresponding positions of the lower case 13. , Whereby the upper case 11 is held openably and closably with respect to the lower case 13.

A skirt portion 16 is integrally formed on the left and right sides of the upper case 11 with the bag portion 12 therebetween, at a height lower than the thickness of the lower case 13, whereby the cartridge body 1 is indicated by an arrow a. Thus, when inserted into the bag portion 12 of the upper case 11, it can be easily guided.

Further, at a position corresponding to the skirt portion 16 of the upper case 11 in the lower case 13, a projection 17 for receiving the skirt portion 16 in a state where the upper case 11 and the lower case 13 are closed is formed. 1 is stored in the case device 10 and the cartridge body 1
Are made so that the bag 12 does not rattle left and right.

In the case of this embodiment, as shown in FIGS. 2 and 3 in which the same reference numerals are given to the portions corresponding to FIG. 1, predetermined inner walls 12A of the bag portion 12 of the upper case 11 are provided. An escape portion 20 having a concave shape with a depth is formed.

The side wall of the concave portion of the escape portion 20 is formed so as to be continuous with the surrounding inner wall 12A with a smooth curved surface, so that the cartridge body 1 is stored in the case device 10 while the cartridge body 1 is housed in the case device 10. Numeral 1 is such that an arbitrary position of the outer peripheral slope is in contact with the side wall of the escape portion 20. Thus, in the case of this embodiment, by forming the relief portion 20, the parting surface 2 of the cartridge body 1 can be prevented from contacting the inner wall 12A of the case device 10.

In the above-described configuration, even when various vibrations are applied when the product composed of the cartridge body 1 housed in such a case device 10 is transported as truck cargo or air cargo, the cartridge body 1 can be removed from the outer periphery. Since it is configured to come into contact with the side wall of the escape portion 20 at an arbitrary position on the slope, it is possible to prevent the occurrence of dusting caused by shavings caused by the contact of the parting surface 2.

According to the above configuration, the cartridge body 1
Inner wall 1 of case device 10 against which partitioning surface 2 contacts
By forming the concave relief portion 20 in 2A, the case device 10 that can prevent the dusting due to the shavings beforehand can be realized.

In the above-described embodiment, the concave escape portion 20 is formed on the left and right inner walls 12A of the bag portion 12 of the upper case 11.
As described above, the present invention is not limited to this. A concave relief portion may be formed as necessary, such as an inner wall of the bag portion 12 of the upper case 11 or an inner wall of a side of the lower case 13 facing the bag portion 12. Even if it does, the same effect as the above embodiment can be realized.

In the above-described embodiment, the present invention is applied to a case in which a 3.5-inch magneto-optical disk housed in a cartridge is used as one disk.
Although the case where the present invention is applied to a case device for storing each sheet has been described, the present invention is not limited to this, and may be applied to a case device for storing a 3.5-inch floppy disk. It is suitable for wide application to case devices that are stored individually.

[0023]

As described above, according to the present invention, a case device in which a cartridge body formed by laminating two injection-molded halves is stored between an openable and closable upper case and a lower case. In the method described above, a relief portion having a concave cross section is formed in a portion of the inner wall portion of the upper case and / or the lower case facing a mating surface protruding outwardly of the cartridge body during storage. Surface may not contact the interior wall portion,
Thus, it is possible to realize a case device that can prevent the dusting due to the shavings.
