Abstract: A reel includes a pair of segments which are demountable from each other and one of which is moulded integrally with a flange, while the other segment includes a segmental inner member and a segmental outer member which are connected by a pair of connecting members at their ends. The outer member is prevented from deforming polygonally by providing a sectorial space between the inner member and the outer member, with a clearance between the inner member or the outer member and the adjacent rib which extends almost across the sectorial space.

Abstract: A storage case for storing a tape cassette that includes a tape reel hub having a cylindrical wall defining a cylindrical recess in the hub with a bottom wall extending across the recess and having a plurality of drive holes formed therein. The case includes an enclosure for receiving and enclosing the tape cassette and a hub engaging member movably mounted in the case for reciprocal movement between retracted and extended positions with respect to one wall of the case. The hub engaging member is located to be received in the reel hub recess when the tape cassette is inserted in the case, and it includes at least one locking button for engaging one of the drive holes of the reel. The hub engaging member is biased towards its extended position to engage the locking button in one of the drive holes of the reel hub when there is alignment therebetween.
