Abstract
An imaging engine includes a multi-functional structure. This structure functions as an optics barrel. In other words, at least one lens is positioned within the structure. In addition, the structure functions as an attachment/mounting apparatus for an image sensor board, an illumination board, and possibly an illumination/targeting lens structure as well. The structure may also provide a mechanism for attaching/mounting the imaging engine to another structure, such as the housing of a graphical code reader.
Claims16
An imaging engine, comprising:
- an optics barrel;
- at least one lens positioned within the optics barrel, wherein the at least one lens focuses light onto an image sensor;
- an image sensor board that is attached to the optics barrel, wherein the image sensor board comprises the image sensor;
- and
- an illumination board that is attached to the optics barrel, wherein the illumination board comprises multiple light sources;
- wherein:
- when the imaging engine is in an unassembled state, the optics barrel comprises a first set of support posts and a second set of support posts;
- when the imaging engine is in an assembled state, the illumination board is attached to the first set of support posts and the image sensor board is attached to the second set of support posts;
- the optics barrel comprises a first set of lenses that are positioned within the optics barrel so that there is a first optical path through the first set of lenses to a first section of the image sensor;
- the optics barrel additionally comprises a second set of lenses that are positioned within the optics barrel so that there is a second optical path through the second set of lenses to a second section of the image sensor;
- and
- both the first optical path and the second optical path pass through a same opening in the illumination board.
