Abstract
Abstract A tape transport assembly for a cassette tape cartridge adapted for releasably mounting the cartridge for a transducing operation. A pivotal headplate is mounted on the base member adjacent to a capstan and carries a pinch roller and a transducer to allow the pinch roller to engage the capstan with the tape for advancing the tape from reel to reel when the plate is swung towards the capstan to effect a transducing operation. A radius arm is pivoted to the transport assembly and pivotally carries the head plate. The radius arm may be automatically controlled for moving it into engagement with a resilient mounting means for the head plate to pivot the radius arm and thereby the head plate to allow a tape rewind operation.
