Abstract
A storage case for housing a magnetic tape cassette is effective for preventing rotational movement of supply and/or take-up reels of such a tape cassette, even if the case is dropped, transported or subjected impact, or the like. The storage case includes upper and lower halves joined by an elongate hinge which are integrally formed. Projected hub portions are provided on the inner surface of the lower half for engaging drive spaces in the hubs of the reels of the tape cassette to be stored. The hub portions are formed with caps made of a material having the same thermal expansion coefficient as a material from which the reels of the tape cassette are made. In addition, a resilient member may be provided around the outer side of the hub portions for providing added insertion force for surely preventing unwanted rotation of the reels even according to long term storage of the tape cassette at varying temperatures.
