In each of these three embodiments, the upper lips and lower ledges or ridges cooperate to receive the borders of a window opening formed in the cassette cover, and a label can be applied between the windows and optionally covering one or more windows. In each embodiment of the method, the window is flexed to position opposing ledges under the borders and the window is returned to its original planar position so that the upper lip abuts the top of the border.

Abstract: A static tape cassette reel lock is described. In one embodiment a tape reel flange has on the outer circumference thereof a plurality of teeth, and the cassette base includes a plurality of slanted vertical ribs and a centered slanted horizontal rib. The teeth of the flange are able to move past the angled ribs so that the tape reel can rotate in one direction, but does not allow rotation in the other direction. In another embodiment the reel hub includes a chamfered ring of teeth. The cassette base includes a corresponding ratchet ring of ramped teeth. Again, rotation in one direction is allowed, but not in the opposite direction.

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.

Abstract: An apparatus for storing a plurality of disc-shaped recording media includes a housing and a plurality of thin, substantially C-shaped lever members, each of which has an inner circumferential surface for holding a disc-shaped recording media by an outer circumferential surface of the recording media. Each lever member is pivotally connected to the housing by a pivot post and is pivotally movable into and out of the housing. A lock mechanism prevents the lever members from pivoting out of the housing, while a detent mechanism holds the unlocked lever members in either a closed or open position. The inner circumferential surface of the C-shaped lever members subtends an angle greater than 180.degree. in order to create a spring force in two arms of the lever member, the spring force acting to hold the disc-shaped recording media on the circumferential surface of the lever member.
