Patent ID: 7686223

Claim:
An aiming pattern assembly for an imaging-based bar code reader wherein the bar code reader includes an imaging system generating image frames of a target object within a field of view and having a working range over which a target bar code within the field of view is capable of being imaged and decoded, the working range being subdivided into a near range and a non-overlapping far range, the near range being closer to the reader and the far range being further from the reader, the aiming pattern assembly comprising: a light source assembly generating focused light; a pattern shaping assembly receiving focused light from the light source assembly and including a first area and a non-overlapping second area, focused light passing through the first area creating a first aiming pattern projected toward the field of view and passing through the second area creating a second aiming pattern projected toward the field of view, a center line of the first aiming pattern intersecting a center line of the field of view within the near range of the working range and a center line of the second aiming pattern intersecting the center line of the field of view within the far range of the working range; and a pattern selection assembly receiving the first and second aiming patterns and passing at least one of the first and second aiming patterns.
