  • LASER BARCODE SCANNER
    Publication number: 20150169924
    Abstract: The present laser barcode scanner employs (i) a simplified scan mechanism made from a semi-flexible substrate that eliminates complicated optical assemblies, (ii) a layout with location features eliminating the need for special alignment, and (iii) a layout with all surface mounted devices on a single layer eliminating the need for extra soldering. Together these strategies, when used with a method of mitigating stray-light by separating light paths with a circuit board, combine to achieve a laser barcode scanner of unique simplicity and performance.
