Abstract
Abstract A casing for receiving a cassette is including a casing body for receiving a tape cassette, the casing body having a rectangular opening, a lid member attached to the minor side of the opening and capable of being opened and closed, and a pair of engaging members provided to the lid and arranged at the same plane as the opening and closing direction of the lid and for regulating the position of reel hubs which are rotatably mounted to the cassette. The engaging member has a slanted portion provided at the opposite position of the tip thereof and for making the central axis of the reel hub eccentric, and a notched portion provided at the opposite position to the slanted portion and for preventing engagement to projections which are formed at the inner peripheral surface of the reel hub.

Claim 1
Independent Claim
261 words
A case for receiving therein a tape cassette having a pair of spaced apart tape hubs with centrally located openings therein comprising: a box member having an open top for receiving therein said cassette, and a first and a second pair of generally parallel opposed sides, said box member being shaped to receive said cassette in a position where said hubs are spaced apart in a direction extending parallel to said first pair of sides; a cover for opening and closing said open top of said box member; hinge means mounting said cover for pivotal movement to open and close said top of said box member along one of the sides of said second pair of sides; and a pair of engaging members mounted on the inner side of said cover positioned for engagement, respectively, within said openings in said tape hubs, one of said engaging members being located closer to said hinge means and the other of said engaging members being located further away from said hinge means; said engaging members each being formed with a pair of opposed slanting surfaces, one surface each of said pair facing toward said hinge means and the other surface of each of said pair facing away from said hinge means; with the slanting surface on said one engaging member facing toward said hinge means being steeper than the slanting surface facing away from said hinge means; and with the slanting surface on said other engaging member facing away from said hinge means being steeper than the slanting surface facing toward said hinge means.
