ABSTRACT:
A compact drive assembly for a hand-held scanner device may comprise a roller mounted for rotation in the hand-held scanner device and a motor having an output shaft. A first worm mounted to the output shaft of the motor engages a first worm gear. A second worm is operatively associated with the first worm gear so that the second worm rotates with the first worm gear. A second worm gear mounted to the roller engages the second worm so that the motor drives the roller via the first worm, the first worm gear, the second worm and the second worm gear. An encoder assembly operatively associated with the second worm provides an indication of the angular position of the second worm. A control system operatively associated with the encoder assembly and the motor operates the motor to drive the roller within a predetermined speed range.
