Abstract
The present invention provides a hand held scanner with a motorized drive capability. The motorized drive employs a clutchless motor system. In manual operation, the scanner operates as a standard non-motorized scanner in which the user can neither see nor feel any effects of the motor system. In the motorized mode, a worm gear mounted on the motor's drive shaft causes the drive gear/friction wheel assembly to engage the drive rollers.
