ABSTRACT:
A cassette reel drive mechanism is disclosed for providing fast forward and reverse drive for the supply and takeup reels of the cassette. The mechanism includes a simple mechanism, all of which is desirably mounted on the shaft of a DC reversible motor, and utilizes a portion of the torque of the motor, coupled through a clutch mechanism, to pivot a linkage arm. An idler wheel is mounted on the arm and is driven by the motor. Pivoting of the arm brings the idler wheel into driving contact with a respective turntable associated with the supply and takeup spindles on which a cassette may be mounted to provide the desired fast forward or reverse drive, and disengages a brake mechanism to allow unencumbered rotation of the appropriate turntable.
