Hand-held optical indicia reader having a controlled oscillating system for optimal indicia reading
First Claim
1. An optical indicia reader for reading information encoded in optical indicia, said optical indicia reader comprising:
- (a) a light source positioned within the indicia reader to illuminate an imaging area located externally of the reader;
(b) an oscillatory system positioned to scan a light beam generated by said light source over optical indicia to be read; and
(c) a controller capable of controlling said oscillatory system;
wherein said controller is capable of directing said oscillatory system to become fixed in position so that the light beam is in a substantially fixed relationship to an aiming axis of the optical indicia reader.

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.
