Abstract
A reel spring including a wire having a flat central portion and two angled arms, each terminating in substantially planar pads, curved portions or pivot buttons. The flat central portion includes two spaced, open loops which receive corresponding projections formed on the cassette cover. The pads, curved portions or pivot buttons abut and bias the tape reel hubs downwardly when the cassette cover and base are mated. The methods of assembly include the steps of moving the loops against the projections until the corresponding projections are received by the loops and caulking or swaging the projections. The wire reel spring can be removed by merely moving the wire reel spring in the opposite direction.
