A magnetic recording and reproducing apparatus comprising leader block guide and drive means to guide and drive a leader block provided at a leading end of a magnetic tape on a single tape reel in a tape cartridge from the tape cartridge to a winding reel having a recess provided therein to mount the leader block on the winding reel so that the magnetic tape is guided along a tape running path including a magnetic head, the leader block guide and drive means comprising a spur gear (20) rotationally driven by a reduction drive mechanism (102,103,104,106,107) and an arm (22) pivotally supported on the spur gear (20) and having a drawing pin member (23) provided thereon to be engageable with the leader block whereby the leader block is guided along a predetermined path to the winding reel (48).

A disk playback device holds a disk in a playback position. A turntable moves toward the disk to a raised position where its support surface is adjacent a back of the disk. A spindle inserts through a center hole of the disk to align the disk with the turntable. A clamper is held above the disk on a side of the disk opposite the turntable. The clamper is supported close enough to the disk that when the turntable is in the raised position, a magnet in the turntable exerts a substantial force on a piece of ferromagnetic material in the clamper. When the clamper is released it clamps the disk to the turntable. By bringing the clamper and turntable to the disk rather than moving the disk toward one or the other, no space is required for the displacement of the disk in a direction perpendicular to its surface. The clamper is supported by a pair of holders, slidable in a direction parallel to the surface of the disk. Wedge-shaped surfaces on the holders engage a flange on top of the clamper to lift and hold the clamper above the disk. If a disk is misaligned with the spindle when the turntable is brought to the raised position, the disk is pressed against the clamper. The clamper in turn presses against inclined surfaces of the holders causing the holders to spread apart. The spreading is detected to invoke a control routine to correct the misalignment.
摘要:
An apparatus for drawing out a leader block (9) in a tape cartridge (5) for a magnetic instrument comprising engagement means (30) movably provided in leader block guide means (25) for guiding and driving the leader block (9) along a predetermined guide path in the form of guide groove (26), for example, so that the leader block (9) is associated with the leader block guide means (25) when the tape cartridge (5) enters the magnetic instrument and is released from the leader block guide means (25) when the tape cartridge (5) is removed from the magnetic instrument.
