Abstract A magnetic tape cassette storage case of a type suitable for storing operational-type video tape cassettes in which the reels can freely rotate when unloaded from a video tape recorder. The storage case is composed of a box-shaped body receiving the tape cassette and a cover for a opening and closing the box-shaped body, wherein the body is provided with engaging parts on an inner surface of the bottom thereof shaped so as to engage with corresponding reel hub holes of the magnetic tape cassette. Each of the engaging parts includes a rotation preventing structure in the form of a discontinuous ring composed of a plurality of protrusions extending from the inner surface of the bottom of the case body inwardly of the case, and a positioning structure arranged inside the rotation preventing structure composed of at least one protrusion extending from the inner surface of the bottom the case body inwardly of the case.
A magnetic tape cassette storage case comprising a box-shaped body for receiving a magnetic tape cassette and a cover for opening and closing said box-shaped body, wherein the improvement comprises: said body has engaging parts on an inner surface of a bottom thereof which are shaped to engage with corresponding reel hub holes of said magnetic tape cassette, and wherein each of said engaging parts comprises: rotation preventing means in the form of a discontinuous ring comprising a plurality of protrusions extending from said inner surface of said bottom of said body inwardly of said case; and positioning means arranged inside said rotation preventing means comprising at least one protrusion extending from said inner surface of said bottom of said body inwardly of said case.
