ABSTRACT:
A compact assembly for electro-optically scanning indicia includes an oscillatable component operative for focusing, and for sweeping, a light beam across the indicia and, optionally, for correcting for scan aberration. A laser diode for emitting the beam is inserted into a central opening surrounded by an electromagnetic coil to conserve space. A magnet on the component interacts with the coil to effect oscillation. A floating flexure returns the component to an equilibrium position.
