ABSTRACT:
A hub drive assembly includes three pairs of pivoted arms, each supporting a friction pad, which may be clamped against the inner cylindrical surface of a tape supply reel. The assembly also includes a central sleeve, rotatably driven by a motor, and a second sleeve concentric with the central sleeve. The second sleeve is provided with gear teeth, which couple with gear teeth of one arm, which in turn couple with gear teeth of the other arm of each pair. Means are also provided to rotate the two sleeves relative to each other, thereby causing rotation of the arms about their pivot points via the gear couplings, so as to bring the frictional pads into, and out of, frictional engagement with the reel.
