Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a protective case for various magnetic recording type floppy disks, and more specifically, storage of floppy disks,
Another object of the present invention is to improve portability, reduce manufacturing cost, improve the effect of preventing damage due to external impact, and enable storage in an upright state.

(Prior Art) Various storage containers have been proposed for storing floppy disks.

Most commonly, there are many structures in which a pair of upper and lower square cylinders made of cardboard are fitted in a cage-like manner in the directions in which their openings are abutted against each other.

Further, as disclosed in Japanese Utility Model Laid-Open No. 59-194179, in consideration of convenience in use, a pair of inner side walls which are made to rise in the same direction at both ends in the width direction by a plastic material are bridged between the inner side walls. A bottom wall having a rotating body, a pair of external side walls that are similarly raised at both ends in the width direction, and a front wall that is raised at the one end in the height direction in the same direction as the external side wall, Further, the upper wall having a void portion formed at the other end portion thereof is rotatable with respect to the left and right outer side wall end portions corresponding to the void portion of the upper wall and the rotary body side end portion of the inner sidewall of the bottom wall. It is known that the structure is bound to.

Further, as disclosed in Japanese Utility Model Laid-Open No. 61-156677, a case body having a back plate, a bottom plate, and side plates erected from both ends of the back plate, and a pivot body pivotably mounted on the case body. In the one that is provided with a supported lid and stores an object to be stored,
There has also been proposed a floppy disk storage box in which the case body is formed of a back plate, a bottom plate, and a side plate, and the side plate is provided with a ridge for holding an object to be stored.

In addition, in order to enhance the magnetic shield effect of storage or transportation containers such as magnetic tapes, magnetic disks, and magnetic recording cards,
It has also been proposed to construct a container with a plastic plate embedded with a net made by weaving ferromagnetic wire. (Jitsuko Sho 49-13890).

(Issues to be solved by the device) However, a container made of cardboard has poor rigidity and durability,
There is a problem that the disc cannot be sufficiently protected, and paper dust is generated when the disc comes in and out, which adversely affects the disc.

Also, in the cases disclosed in Japanese Utility Model Publication No. 59-194179 and Japanese Utility Model Publication No. 61-156677, since all of them are containers made of transparent hard plastic, the disk moves inside the container and is damaged. It is not suitable for portable use because it is inferior in impact resistance against dropping and drops, it is inadequate for magnetic protection of floppy disk due to poor magnetic shield property, and it is difficult to print on the container itself and designability There is a problem that it is poor.

Furthermore, in order to improve the magnetic protection of plastics, even in the case of a structure in which a net made by weaving a ferromagnetic wire in a plastic plate is embedded as in Japanese Utility Model Publication No. Sho 49-13890, the processing is remarkable. There are various problems that are impractical because they require labor and experience.

(Means for Solving the Problems) The present invention solves various problems in the above-mentioned conventional technology, has easiness of processing, cost reduction, and impact resistance, and protects, saves, and carries a floppy disk. Which is most suitable for, specifically, a metal lower lid and an upper lid that can be opened and closed by a hinge mechanism, and an inner plate that can be stored in the lower lid. The opening edge is curled inward and the opening edge of the top lid is curled outward. By providing projections that also project inward at symmetrical positions, they serve as contact parts with the curl portion in the lower lid when the lid is closed, and the cushioning material is attached to the inner surface of the upper lid, and Project toward the bottom And a flange that can be engaged with the inner curl portion of the lower lid is formed at the opening edge thereof, and the opening / closing side edge of the upper lid has a length substantially equal to the length of the upper lid, The present invention relates to a floppy disk protection case in which a rectangular index is attached that substantially matches the height of the lower lid when the upper lid is closed.

(Function) However, in the present invention, when the upper lid is opened, one or more floppy disks are accommodated in the inner plate, and the upper lid is closed again, the floppy disk is pinched between the cushioning material of the upper lid and the inner plate. It can be retained, stored as it is, and used for carrying. Further, a constant gap is maintained between the upper lid and the lower lid by a cushioning material, and between the lower lid and the lower lid by a concave projection. As a result, the floppy disk accommodated is adversely affected even when an external impact is applied. Never.

Furthermore, when the index is attached to the top lid, the title and contents of the stored floppy disk can be displayed on the surface, and it is easy to take out from many stored,
It can be stored in a state of standing upright on a large number of storage shelves using the square index end faces.

(Embodiment) The concrete contents of the present invention will be described below with reference to an embodiment shown in the drawings. Reference numerals 1 and 3 are plate-shaped metal lower parts configured to be opened and closed by a hinge mechanism (not shown).
