    摘要: A plate spring for tape cassettes advantageously consists of two long and two short spring arms whose shapes and dimensions are optimized to achieve minimum wastage of material during punching from a sheet-metal strip. The length of the fastening arms is preferably about the same as the width of the ends of the long spring arms or less or at most 1.5 times the width. The spring can be used for all types of tape cassettes, regardless of whether they contain magnetic tape, film or other recording media. A tape cassette possesses a plate spring which has this form and is fastened by welding.

    摘要: A transparent window member for a tape cassette, which together with a reel pressure spring, forms a subassembly of the cassette. The reel pressure spring has a U-shaped central portion, the bight of the U being parallel to the plane of the spring arms, and the reel pressure spring having a longitudinal edge with two transverse slits spaced the same as the legs of the U of the central portion of the pressure spring. The central portion may thus be transversely inserted in the longitudinal edge of the window member and it thus forms a locating element for the pressure spring.

    摘要: A tape cassette is provided with a pressure plate spring which has a tape-length indication comprising indicator elements which have been cut in or cut out mechanically. Advantageously, both long arms possess such indicators, which may even be of different types. In a particularly advantageous spring shape, one long spring arm has an edge possessing incisions and the other long spring arm has an edge possessing projections, as a result of which the springs can be arranged for punching in such a way that waste is avoided.

    摘要: A packaging container (1) for a tape reel device, e.g. a tape cassette, which has one or more reel-locking elements (9, 10) possesses on at least one of these elements (9, 10) a friction element (14), e.g. of rubber, for holding and, if necessary, clamping the reel of the tape reel device. The element (14) can be annular, rib-shaped or knob-shaped, and can be used for any type of tape reel, inside or outside audio, video or film cassettes.
