SYSTEM AND METHOD FOR READING BAR CODE USING LASTER BEAM

摘要

PURPOSE: A system and a method for reading bar code using a laster beam are provided to increase the readability by generating a rate value of a laster beam reflected and projected from a reading object, by rearraying the value according to a movement direction of the laster beam, by reproducing a rate value using the density of the beam, and by detecting the condition of a bar. CONSTITUTION: A bar code reading system is largely composed of a bar code reader(10), a decoder(20) and a controller(30). In case that a height adjustment value of a beam is set by an input device(32) of the controller(30), an input/output controller(31) transmits a scan height value of the laster beam to a control unit(40). A scan height adjustment setting device(13) sets up a scan area of the beam.
