ABSTRACT:
A fully automatic bar code symbol reading system which has 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 of the portable unit without a physical wiring connection to the portable unit. The hand-supportable bar code symbol reading device produces a narrowly confined scanning volume for omnidirectional scanning of code symbols presented within the scanning volume, while preventing unintentional scanning of code symbols on nearby objects located outside of the scanning volume.
