Claims

1. A cartridge accommodating case for accommodating flat body-shaped cartridges in each of which a reel with a magnetic tape wound therearound is disposed, comprising: an upper case; anda lower case, the upper case and the lower case being adapted to be superposed on each other to form at least one partitioned chamber for holding a cartridge group formed into a block by juxtaposing a plurality of cartridges in a thicknesswise direction thereof,wherein a tab is extendedly provided on a peripheral edge of each of the upper case and the lower case.

2. The cartridge accommodating case according to claim 1, wherein each of the upper case and the lower case is formed by a quadrangular outer shape having four corner portions at its periphery, and a bevel portion is formed at at least one corner portion of each of the upper case and the lower case by removing the corner portion along an inclined side, the tab being formed on the bevel portion.

3. The cartridge accommodating case according to claim 2, wherein the tab extendedly provided on the bevel portion is formed on an inner side of a quadrangular region enveloping four outer sides of the case.

4. The cartridge accommodating case according to claim 2, wherein the bevel portion is formed at at least two adjacent ones of the corner portions, and the tabs extendedly provided respectively at the two corner portions are each disposed in such a manner as to be offset from a center of the inclined side of the bevel portion.

5. The cartridge accommodating case according to claim 1, wherein each of the upper case and the lower case is constituted by an integrally molded piece of a plastic resin.

6. The cartridge accommodating case according to claim 5, wherein the plastic resin includes at least one of polyethylene terephthalate, polypropylene, and polystyrene.

7. The cartridge accommodating case according to claim 5, wherein the plastic resin is translucent.

8. The cartridge accommodating case according to claim 5, wherein each of the upper case and the lower case is formed by subjecting a plastic resin sheet having a thickness of from 0.5 to 2.0 mm to drawing.

9. The cartridge accommodating case according to claim 1, wherein the upper case and the lower case have an identical structure for forming the partitioned chamber by engaging with each other and each have a tapered shape in a direction away from an engaging portion thereof, and biting preventing means are provided which have different shapes at portions at diagonally opposing positions within a range of a peripheral edge portion of the case.

10. The cartridge accommodating case according to claim 9, wherein each of the biting preventing means is a portion of a cushioning rib which is projectingly formed on an outer side surface including the range of the peripheral edge portion of the case.
