A cassette tape deck for use with a tape cassette having a magnetic tape wound on reels in a casing, which is designed to record signals on the tape or reproduce them therefrom based upon loading of the cassette, and in which at least one guide pin having slidably mounted thereon a sliding member biased toward the upper end of the guide pin and the sliding member has formed therein a groove or aperture extending perpendicular to the sliding direction thereof and has associated therewith a movable member biased toward the guide pin, whereby when the cassette has been loaded on the tape deck at a predetermined position, the groove or aperture of the sliding member receives the movable member to detect the loading of the cassette at the predetermined position and actuation of tape driving means is allowed based upon the detection of the loading of the cassette; in which left and right braking members attached to a lever associated with left and right actuating levers for urging left and right pinch rollers into rotary contact with left and right capstans with the tape being gripped therebetween respectively and for pressing the magnetic head against the tape is selectively brought into contact with left and right wheels mounted on left and right reel shafts, whereby the tape is driven across the magnetic head while being subjected to required back tension; and in which the tape is driven to the right (or left) under such conditions that left and right pinch rollers are held in rotary contact with left and right capstans with the tape being gripped therebetween respectively and the contact pressure of the left (or right) pinch roller to the left (or right) capstan is held lower than that of the right (or left) pinch roller to the right (or left) capstan, whereby the tape is driven across the magnetic head while being subjected to required back tension.

A tape feeder in a tape recorder comprising, a pair of reel support drive gears mounted on a pair of reel supports, a pair of tape winding gears capable of being brought into or out of mesh with the corresponding reel support drive gears, a pair of capstans driven by a motor for rotating the corresponding tape winding gears, a pair of pinch rollers connected to a head base plate and capable of being brought into and out of pressing engagement with the corresponding capstans, a pair of reverse action members rotatably supported on the corresponding capstan bearing, a pair of springs provided to the corresponding reverse action members, said springs being adapted to press the pinch roller against the capstan when the head base plate advances and at the same time urge the tape winding gear to mesh with the reel support drive gear, and a slider member slidably provided between the pair of reverse action members.
A recording and/or reproducing apparatus (1), for a record carrier (2) in tape form which extends between two rotatingly driveable hubs (4, 5), has two winding spindles (10, 11) for driving the hubs, each of the winding spindles being connected to one drive wheel (12, 13). For braking the two drive wheels (12, 13), a braking device (30) is provided which has a carrier (33) displaceable perpendicularly to a plane (34) through the axes (31, 32) of the two drive wheels (12, 13) and having two braking surfaces (39, 40) for the two drive wheels. The carrier (33) is of frame-shaped design and has two carrier portions (35, 36) passing through the plane (34) through the axes (31, 32) of the two drive wheels (12, 13), each of which carrier portions is arranged so as to run laterally along one of the two drive wheels (12, 13) outside the region between the two drive wheels (12, 13).
A magnetic tape cartridge and tape transport apparatus for use therewith, comprising a cartridge housing and a support which is movable inside the housing in all directions in the plane of the latter and on which hubs are rotatably mounted, between which hubs a magnetic tape can be wound to and fro, and further comprising spring elements which urge the support toward the front wall of the housing, which wall is provided with openings, the tape transport apparatus having means for receiving the cartridge housing, for which guide elements and actuatable locking means are provided, and a magnetic head and capstans which can pass through the openings in the front wall, the capstans being urged, by spring pressure, into contact with the rolls of magnetic tape.
This invention relates to a tape transport for use with a transducer to transport tape along a predetermined path extending past the transducer, comprising two capstans, each disposed at a respective end of the predetermined path; two rollers, each disposed adjacent a respective one of the capstans and arranged to guide tape beyond the respective end of the path in partial wrapping engagement about its respective capstan; two motors each coupled to a respective one of the capstans; and a control circuit coupled to the motors and arranged to control operation thereof to drive the capstans at differing torques whereby to induce a controlled tension in tape extending along the path. One of the motors is driven by an independent source of signals, and the other is driven so as to be dependent, in part, of the operation of the first motor.
A unit for transmitting the movement of a motor to the cassette spool driving gears in an autoreverse cassette tape recorder is disclosed comprising a drive mechanism automatically operating in normal forward and reverse and in fast forward and rewind both for normal forward and reverse operations and a braking mechanism adapted to automatically brake both in normal forward and in reverse and in fast forward and rewind. The drive mechanism has first and second double gears carried by a movable support, an operation lever for the support, a control mechanism for the operation level, and a transmission output mechanism. The braking mechanism has an elastic plate pivoted in the middle between two cassette spool driving gears and a disc pivoted with the plate.
