Abstract
A cassette accommodating case in which a tape cassette can be inserted in either a forward or backward orientation, and for preventing slackening of a magnetic tape, and to secure the tape cassette to eliminate play. Positioning projections having inclined surfaces are provided on each side of a casing section. When the casing section and a cover section are closed, the inclined surfaces abut against the ends of side projections on side surfaces of the tape cassette to push the tape cassette when the casing and cover sections are closed. A rotation-preventing projection of an accommodating case protrudes into a common area of the hubs when a cassette is loaded in the forward and backward orientations, and the projection includes two plate-like portions of different heights, disposed in parallel, and with a predetermined interval therebetween. A distal end of the long plate-like portion has a guiding inclined surface for correcting the positional offset of the hub by contacting its inner peripheral surface. The hub is retained by the two plate-like portions. Backward-pressing surfaces are provided in opposing corner portions of the case to secure the cassette tape within the case.
