    摘要: This invention relates to a tape transport mechanism, particularly an improved contact winding tape transport system modified to protect it against tape transport disturbances occasioned by mechanical impacts. A shock-resisting coupling means is provided which is allocated to the reel carriers and which allows slow movements of the carriers toward and away from a drive capstan during normal working of the mechanism but prevents sudden movements of the carriers induced by mechanical shocks for instance. Piston/cylinder assemblies and magnetic rope/drum arrangements are disclosed as such shock-resisting means. The transport mechanism can be used advantageously in portable apparatus, preferably in magnetic tape recorders and especially in video cameras.

    摘要: 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.

    摘要: 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.

    摘要: A tape cassette has a two-reel brake system having identical brake levers and an actuating element possessing actuating arms for the brake levers, the actuating arms being arranged at least close to the ends of the swivel axle. The brake system is suitable for all two-reel tape cassettes, in particular video cassettes.
