Multiple aperture data reader for multi-mode operation
First Claim
1. A data reading device comprisinga housing;
- a first window disposed on a first side of the housing;
a rotating facet wheel within the housing, the facet wheel having a facet wheel axis;
a light source producing a reading beam directed onto the facet wheel;
first generating optics for generating a first scan pattern passing through the first window;
wherein the rotating facet wheel includes at least one corner comprised of a corner cube containing first and second corner facets disposed at an inward angle perpendicular to one another, the corner facets intersecting to form a line which is parallel to the facet wheel axis.

Abstract
A data reader and method for data reading, such as a barcode scanner, wherein the scan pattern generating optics and other features are optimized for different modes of operation. In a preferred embodiment, different patterns are projected from different apertures in the scanner housing, one scan pattern optimized for handheld operation and the other optimized for fixed operation. Other optimizable features include the presence or absence of an aiming beam, which may be generated from the same laser source as the scan pattern or from another source, and enabling or disabling decoding of the signal received signal during a portion of a facet wheel rotation. Decoding may be disabled while the scan line(s) for handheld use is generated unless a switch or trigger is actuated.
