  • Patent number: 4736904
    Abstract: 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.

  • Patent number: 4687157
    Abstract: 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.

  • Patent number: 4210266
    Abstract: A device for ejecting a loop of leader tape from a magnetic tape cassette, in which a portion of the leader tape is blown out of the cassette so as to form a loop, by means of a stream of air issuing from at least one nozzle which is connected to a source of pressurized air and projects into one of the apertures in the front wall of the cassette which is located in a holder.

  • Patent number: 3977626
    Abstract: A magnetic tape cartridge having at least one tape pack contains liners which form guide channels for the outer turns of the pack and/or for magnetic tape being wound or unwound and also include resilient sections for locating the tape pack and/or the winding hub in the central plane of the cartridge. The magnetic tape cartridge of the invention can be used with particular advantage as a compact cassette beacause of its outstanding reliability in operation.

  • Patent number: 3942744
    Abstract: The invention relates to magnetic tape cartridges in general in which between the tape packs and the upper and lower cartridge walls liners are provided which have regions that resiliently guide the tape packs and/or the magnetic tape. By means of specifically shaped regions of the liners, guide channels for the outer turns of the tape pack and/or for the winding or unwinding magnetic tape are formed according to the invention. By virtue of particular spatial arrangements of these guide channels, slipping and folding of the turns of tape already wound is avoided and the magnetic tape is maintained in the correct position as it leaves and joins the packs, irrespective of the type of bearing means used for the tape winding reels and irrespective of the shape of the tape packs, so that disturbances in operation are avoided and the tape is correctly positioned relative to the scanning means.
