ABSTRACT:
A tape drive system for tape play-back and/or recording devices is disclosed herein. The drive system comprises a first belt driven flywheel whose sole purpose is to control the rotary motion of a tape capstan. A second flywheel, which is also driven by the same belt that drives the first flywheel, is selectively coupled to a toothed pinion which is in constant meshing engagement with a toothed wheel rigidly connected to the collecting reel shaft of the play-back and/or recording device. For fast forward operation an idler pulley, which is directly driven by the same belt that drives the first and second flywheels, has a toothed surface coupled to the pinion while the pinion is decoupled from being driven by the second flywheel. For fast rewind operation, the toothed surface of the idler wheel is directly coupled to a mating toothed surface of a wheel rigidly connected to the supply reel shaft of the play-back and/or recording device while the second flywheel is again decoupled from the toothed pinion. The positioning of the idler wheel is controlled by movement of a T-shaped lever pivotally mounted at two points to the frame of the play-back and/or recording device.
