摘要:
A tape cassette has a housing, at least one tape reel, a front wall and a pressure spring for exerting a spring force on the tape reel(s). The pressure spring is held, e.g. jammed or wedged, between the front wall and a connecting pin connecting parts of the housing together by means of anchoring means forming part of the spring itself.

A guide means for tapes to be transported, in particular in tape cassettes or tape apparatus, comprises a support element and a flexible guide strip, in particular one made of metal foil, fixed on this, and at least one holding element for the end sections of the flexible guide strip. The guide strip possesses a predetermined thickness and may be drop-shaped or pear-shaped in the operating position. The tape guide means may also comprise a support element whose surface is at least partially cylindrical and a flexible guide strip which is fastened thereon. As a separable unit which can be preassembled, the tape guide means can therefore also be employed for automatic manufacture. The tape guide means can be used for tape guides which are either stationary or movable within limits, in the field of tape-like recording media, such as films, magnetic tapes, punched tapes, etc.

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.
