ABSTRACT:
A placing stand for use with a microfilm copying device or the like is driven by means of a step motor connected to the stand by wires or the like. A flywheel is coupled to the shaft of the step motor via a one way clutch so as to damp vibrations of the step motor, while allowing the stand to be quickly returned; the flywheel is not a load on the motor in the return direction.
