Abstract
An automatically-activated laser scanning 2-D bar code symbol reading system employing a visible linear-type laser scanning pattern and an audible feedback signal during scan data capturing and buffering operations. The system includes a laser scanning 2-D bar code symbol reading mechanism that automatically produces a visible linear-type laser scanning pattern for scanning a 2-D bar code symbol structure on an object as its hand-supportable housing is manually transported past a 2-D bar code symbol along a height-wise direction by an operator, automatically capturing lines of scan data from the scanned 2-D bar code symbol structure, decode processing the scan data, and generating a symbol character data string representative of the read 2-D bar code symbol.
