Automatic hand-supportable omnidirectional laser projection scanner with scan-head directed projection axis for intuitive hand-supported omnidirectional scanning of bar code symbols within a narrowly confined scanning volume extending thereabout

摘要

A fully automatic bar code symbol reading system comprising an automatic (i.e., triggerless) portable bar code symbol reading device with an omnidirectional projection laser scanning engine mounted within the head portion of its hand-supportable housing, and an associated base unit positioned within the data transmission range thereof without a physical wiring connection thereto. The hand-supportable bar code symbol reading device produces a narrowly confined scanning volume for omnidirectional scanning of code symbols presented therein, while preventing unintentional scanning of code symbols on nearby objects located outside thereof.
