Abstract
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.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
101 words
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.
Claim 2
Dependent Claim
101 words
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.
Claim 3
Dependent Claim
115 words
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 with a light beam; (b) an oscillatory system positioned to scan the light beam generated by said light source over optical indica 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 a position that will direct light beam to an area in the neighborhood of an aiming axis of the optical indicia reader throughout a reading range of the optical indicia reader.
Claim 4
Dependent Claim
115 words
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 with a light beam; (b) an oscillatory system positioned to scan the light beam generated by said light source over optical indica 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 a position that will direct light beam to an area in the neighborhood of an aiming axis of the optical indicia reader throughout a reading range of the optical indicia reader.
Claim 5
Dependent Claim
31 words
The optical indicia reader according to claim 2 wherein the controller directs said oscillatory system to become fixed in position when the optical indicia reader is in a proximity sensing mode.
