Abstract
Abstract In bar code symbol scanning systems employing laser, optical and sensor components, mirrorless scanner arrangement mounts one or more of these components on a drive for repetitive reciprocating movement either about an axis or in a plane to effect scanning. The system has a movable exit port to permit scanning from opposite sides of a housing.
