摘要:
A tape cassette (79) has a separate, plastic molded, elongated, tape guide subassembly (80), which incorporates two bearing extensions (116,118) integrally molded at the left and right ends thereof. Each bearing extension has a pair of opposing, parallel, planar members (120,122) extending from support members (123) each of which is parallel to the planar top and bottom of the tape guide subassembly. Each planar member includes a roller receiving means (124) integrally formed therein and the rotational axles for the tape rollers (110) are either integrally molded as part of the bearing extension or the tape roller itself. The planar members in each pair have the ability to flex only in the direction perpendicular to their planes, allowing the rollers to be easily snapped into place during assembly. Once the rollers are inserted into the tape guide subassembly, the latter is assembled into the front of the tape cassette, wherein the rollers form part of the central tape support area of the tape cassette. Related methods are also described for manufacturing the tape guide subassembly and the whole cassette.

摘要:
A write enable tab (12) is repeatedly movable from a first position, enabling writing on a signal storage unit, to a second position, disabling writing thereon. The write enable tab preferably includes a central body (42) and a flexible member (46) which exert force against first and second walls of a tape cassette shell. The flexible member is attached at a first end to the central body. A second end (52) of the flexible member projects into first and second depressions in the first wall when the central body is in the first and second positions, respectively.
摘要:
There is disclosed a storage container for a recording medium, e.g. a compact disc comprising (a) a base (12); (b) a recording medium holder (14) including means (16) for holding the recroding medium thereon and being pivotally attached at a first end (54) thereof to a first end (24) of the base such that a second, free end (64) thereof is adapted for movement between a first position and a second position; (c) a cover (20) pivotally attached at a first end (90) thereof to the first end (24) of the base; and (d) means (22) for actuating movement of the holder relative to the base, whereby, when the cover (20) is pivoted relative to the base (12), the actuating means (22) causes the holder (14) to move from the first position to the second position and to present the recording medium (18) for use away from the base (12). There is also described a method of manufacturing such a storage container.
