ABSTRACT:
A barcode information recognizing and processing method enabling a high speed scanning to be obtained and no error in reading the barcode information to occur.
The method comprises storing to an accumulator by a microprocessor (15) a parity discrimination signal (PRT), count signals of one character (CTa, CTb, CTc), a count signal (CTa+CTb) indicating the total length of one character, and a similar character discrimination signal (VAMB) which are outputted in turn from a FIFO memory 14 of a barcode reader decoding system.
Storing shares (M1)(M2)(M3) obtained by dividing the count signal (CTa+CTc)by the count signals (CTa), (CTb), (CTc), respectively; and
transmitting through a transmitting/receiving unit 16 a denary data according to a result obtained by recognizing an original barcode information from said shares (M1), (M2), (M3).
