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.
