Abstract
A barcode scanning head includes a body portion having a first pathway for discharging light and a second pathway to receive light. The second pathway is disposed at an angle from the first pathway to form a fixed focal point position in front of the scanning head.
Claims24
An optical scanner head for use in a scanner device, comprising:
- a body portion including a first pathway to discharge light and a second pathway to receive light, the second pathway disposed at an angle from the first pathway, wherein the angle forms a predetermined focal point position of the optical scanner head;
- wherein light discharged from the first pathway is isolated from the second pathway, the first and second pathways forming a centralized opening, comprised of side-by-side holes, in a front face of the optical scanner head;
- wherein each pathway is configured with an identical cross-sectional shape, the shape chosen from the group consisting of circular, oval, and of a geometry having at least three sides;
- wherein each of the pathways have corresponding front and rear ends, the front ends disposed alongside each other and the rear ends disposed laterally from each other;
- wherein one pathway and an adjoining pocket is adapted to receive the photoemitter assembly and the other pathway and an adjoining pocket is adapted to receive the photodetector assembly;
- and
- wherein each pathway and adjoining pocket is identical, each pocket having a respective upstanding, centrally disposed pin projecting from the floor that is aligned with the photo axis of the respective pathway.

A scanner device comprising:
- a housing formed of a top piece connectable to a bottom piece, a front of the housing including an opening in communication with an interior of the housing;
- an optical scanner head received within the interior of the housing;
- an attachment assembly for holding the optical scanner head adjacent the opening;
- and
- a manual operator push button, the push button disposed within the interior behind the optical scanner head and having a front ledge surface that abuts a back end of the optical head scanner, thereby preventing longitudinal movement of the optical scanner head.
