ABSTRACT:
A tape clamp mechanism for the reel hub of a tape cassette has a clamp block for clamping a tape to the reel hub. The clamp block has a main block having spaced opposite ends, an outer curved surface and an inner surface corresponding to the outer circumferential curved surface of the reel hub. A first pair of prongs project from the inner surfaces of both ends of the clamp block. A bridge member is provided on the inner surface of the main block. A second pair of prongs projects from the bridge member. The reel hub has a recess for receiving the clamp block. The recess has cavities for interacting with the first and second pairs of prongs of the clamp block. The clamp block is settable in the recess of the reel hub by a snap mounting or friction fit mounting method.
