Abstract
Abstract An optical reader is suitable for reading 2-dimensional indicia. The optical reading device, that may include a bar code reader, comprises a lens assembly and a guide detachably mounted on a front portion of the housing for establishing a distance between the lens assembly and an equipment target that is displaced a predetermined distance from a mark target wherein the optical reader further comprises an attaching member for supporting the lens assembly on the guide to form a detachable lens-guide assembly.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
143 words
A hand held optical reader comprising: a housing; a lens assembly having an optical axis, and a depth of field; and a guide detachably mounted on a front portion of said housing for establishing a distance between said lens assembly and an equipment target that is displaced a predetermined distance from a mark target, said guide having a proximal end adapted to be mounted on said housing, and a distal end adapted to contact the equipment target, and means for supporting said lens assembly on said guide to form a detachable lens-guide assembly; and an imaging assembly mounted to said housing in image receiving relationship to said lens assembly; wherein the length of said guide is such that the positioning of said distal end on said equipment target assures that said mark target is within said depth of field of said lens assembly.
