Cartridge accommodation case

Abstract

A case 100 for accommodating cartridges 27 each of which incorporates a magnetic tape reel 25 is provided with plural partitioned rooms 33 for holding respective cartridge groups in each of which plural cartridges 27 are arranged side by side in their thickness direction so as to assume a block form, and a partition 33 (grooves 53a) formed between partitioned rooms 33 arranged in the axial direction of the magnetic tape reels 25.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a cartridge accommodation case for accommodating (flat-body-shaped) cartridges each of which incorporates a magnetic tape reel. More particularly, the invention relates to an improved technique which increases the resistance to impact on the accommodated cartridges as well as the efficiency of the work of housing cartridges.BACKGROUND OF THE INVENTION[0002]Conventionally, to pack one-reel-type magnetic recording tape cartridges together, as shown in FIG. 4, one cartridge 1 is housed in each case 3 and plural cases 3 are packed in a corrugated cardboard box 5. Necessary buffering performance is thus attained.[0003]However, in this accumulated packing, since cartridges 1 are accommodated in a corrugated cardboard box 5, to check the presence / absence, types, etc. of cartridges 1 it is necessary to open the corrugated cardboard box 5, which is low in convenience. Another problem is that in the event of flooding a corrugated ca...

Benefits of technology

[0009]The present invention has been made in view of the above circumstances, and an object of the invention is therefore to provide a cartridge accommodation case capable of realizing high efficiency of housing work and assuring the quality of cartridges by securing sufficient resistance to impact.

[0027]According to this cartridge accommodation case according to the invention, even if impact is exerted on it in the axial direction of the magnetic tape reels when it is dropped, an external object collides with it, or a like event occurs, the partitions absorb part of the impact and thereby prevent the magnetic tapes from hitting the flanges of the magnetic tape reels. The quality of the cartridges can thus be assured. Furthermore, the accommodation case is produced by performing integral forming on a plastic resin and one partition is projected inward by forming at the prescribed height. Therefore, the accommodation case is given a certain degree of elasticity along this partition and this partition can make some contribution to absorption of external impact. As such, the accommodation case can hold the magnetic cartridges in the prescribed winding state and thereby assure the quality of the cartridges. Still further, since in a partition forming process the degree of drawing in the side walls of the accommodation case is set equal to the prescribed value corresponding to desired case elasticity, the optimum degree of drawing can balance the rigidity and the impact absorbing ability of the accommodation case.

Problems solved by technology

Therefore, in actual housing work, cartridges 1 are put into the case 7 one by one, which is inconvenient particularly in the case where a large number of cartridges 1 need to be stored.

This raises a problem that the case 7 is low in the resistance to impact and hence in the ability to absorb impact when the case 7 is dropped.

In the worst case, reading and writing are disabled.

Therefore, a problem remains that it is difficult to prevent each magnetic tape from contacting its flange.
