The invention relates to a magnetic tape cassette and a tape recorder for use with such a cassette. More specifically, the invention relates to the provision of movable holding means within the cassette, which means -- in a first position -- prevent unwinding of the packs of tape and thus hold the magnetic tape taut and -- in a second position -- release the packs and the magnetic tape for operation in conjunction with guide, scanning and driving means on the recorder. The said holding means are in the form of spring elements which engage teeth in the hubs to prevent the packs from unwinding. In a special embodiment, the holding means are in the form of flat members, one on each side of the packs between the side surfaces thereof and the upper and lower walls of the cassette, individual springs being provided which resiliently support said members relative to the wall of the cassette and permit movement of said members from a first, pack-locking position to a second, pack-releasing position.

A locking/unlocking means for cassettes, in particular those having swivel cover flaps, consists partially or completely of elastically deformable material and is pivotably mounted at two or more points. In the rest position of the locking/unlocking means, advantageously a swivel plate, an essentially tension-free arrangement is obtained by means of a supporting extension above the bearing axis, by actuation from outside, the said arrangement being converted in the operating state, without further spring elements, into a state of tension and into a position in which the supporting extension rests against the inside of an outer cassette wall and a reaction force corresponding to the actuating force is generated without any additional spring. Such a locking/unlocking means is suitable for cassettes of all types.

A magnetic tape transport apparatus wherein at least one capstan simultaneously drives the take-up and supply reels, and wherein tape tension is generated by a braking device allotted to each tape reel, each braking device consisting of an assembly of levers (A, B, C, and D, E, Z) and a braking cable which is wound around the axle supporting the tape reel, and by means of which the braking forces are so adjusted that it is always the axle of the supply reel which is braked, while the axle of the take-up reel runs relatively freely. In a practical embodiment, the lever assembly comprises at least three hingedly connected levers (A, B, C and D, E, Z), viz. two lateral levers and an interconnecting lever, it being possible to obtain different lever arrangements by varying the locations of the movable pivot points (G) and the fixed fulcrum points (F) FIGS. 1 to 3). The tape transport with such braking devices is suitable for all types of magnetic tape recorder, such as audio, video and data recording apparatus, and can be used with particular advantage in compact portable recorders.

The invention relates to a process for the manufacture of a tape guide of large surface area for tape transport apparatus and to the tape guide manufactured thereby. In manufacturing the guide, a strip of material is elastically deformed, after which the deformation is maintained. One of the sides of the strip of material serves as guide surface for the magnetic tape. The strip can be located on the periphery of one or more bodies, if appropriate in a groove provided therein, and can be attached to the said bodies by suitable means, for example with the aid of integral hooks provided at the ends of the strip.The guide may be used for all types of tape transport apparatus. Since the guide of the invention offers extremely accurate tape guidance, it can be used particularly advantageously for magnetic tapes having a plurality of tracks and transported at a high speed, such as is usual, e.g., in video recording or in the recording of digital data.

A magnetic tape cartridge consisting essentially of two hollow boxes which are connected together, by means of a closing spring, with their single open sides facing each other so as to be pivotable in one plane, a closing force being exerted upon said hollow boxes by said spring. This magnetic tape cartridge is suitable for all applications where cartridge halves must be frequently pivoted relative to one another, while being economical to manufacture.

A container for tape cassettes is provided with one or more locking elements which comprise one or more ring segments which are roughly adapted to the drive orifice of the cassette. An advantageous embodiment is formed integrally with a web and, preferably, an ejector peg. Overlaps in the edge contour part of a joint and the height of the peg adapted to the internal dimension of the container provide greater stability to lateral compressive forces and forces acting during fall.

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 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.
