ABSTRACT:
A case arranged such that a cover having a pocket and a casing portion having stoppers are pivotally secured to each other in the manner of a door, in which the stopper is formed such that a portion coming into contact with spokes of the cassette has a bent or curved portion extending substantially along the direction of winding and tightening the hub. The curved or bent portion is provided with an inclined upper end surface for decreasing the projecting height in the direction of its projecting end. Accordingly, when the cover is closed with respect to the casing portion after the magnetic tape cassette is placed in the pocket, the spoke is engaged with the inclined upper end surface of the stopper, so that the spoke is guided along the inclined upper end surface in the direction of winding and tightening the magnetic tape, thereby allowing the hub to rotate and effecting the winding and tightening of the tape. After the tape is wound and tightened, the spoke is finally retained at the terminating end or in the vicinity of the terminating end of the curved or bent portion. Hence, shaking movement of the hub in the loosening direction is prevented, thereby preventing tape slackening when the cassette is stored in the case.
