Abstract
An optical indicia reader for reading information encoded in optical indicia is disclosed. In one embodiment of the invention, the optical indicia reader comprises a light source positioned within the indicia reader to illuminate an imaging area containing optical indicia, an oscillatory system for scanning a light beam over the optical indicia, and a controller for controlling the oscillatory system. The controller is capable of directing the oscillatory system to position the light beam in a fixed relationship to an aiming axis of the reader. The oscillatory system may be fixed in position when the optical indicia reader is in a proximity sensing mode.
