Abstract
Reel leaf spring/cassette cover combinations are described, wherein the leaf spring is removably mounted on the cover. In a cam fit embodiment, the spring is held within opposing pairs of projections. In a press fit embodiment, the spring includes lateral pointed members, which are caught between parallel projecting members formed on the cover. A related method of assembly includes the steps of: forming a cassette cover to include a plurality of opposing projections; inserting a leaf spring against the cover diagonally between the projections; and rotating the leaf spring to be removably engaged by the projections. In an alternate embodiment, the leaf spring includes lateral pointed members and the spring is installed straight down, such that the pointed members catch the plurality of projections.
