Multiple aperture data reader for multi-mode operation
First Claim
1. A data reading device comprising a housing;
- a first window disposed on a first side of the housing;
a second window disposed on a second side of the housing;
a beam scanning mechanism within the housing;
a light source producing at least one reading beam directed onto the beam scanning mechanism;
first generating optics for generating a first scan pattern passing through the first window;
second generating optics for generating a second scan pattern passing through the second window, wherein the first scan pattern is optimized for fixed mode scanning and the second scan pattern is optimized for portable mode scanning.

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.

22. A method of producing a scan line comprising the steps of:
-
arranging a facet wheel with a plurality of primary mirror facets;
arranging a corner between a pair of the mirror facets, the corner comprising first and second corner facets disposed at an inward angle relative to the primary mirror facets;
rotating the facet wheel;
directing a light beam onto the rotating facet wheel;
scanning the light beam by double reflecting the light beam impinging on the first and second corner facets, wherein the light beam impinging on the first corner facet is reflected off the first corner facet and onto the second corner facet and out into a scan volume, and wherein the light beam impinging on the second corner facet is reflected off the second corner facet and onto the first corner facet and out into the scan volume.
