Abstract
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).

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
113 words
A barcode information recognizing and processing method comprising the steps of: 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 (first-in first-out) 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 share (M1), (M2), (M3).
Claim 2
Dependent Claim
113 words
A barcode information recognizing and processing method comprising the steps of: 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 (first-in first-out) 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 share (M1), (M2), (M3).
Claim 3
Dependent Claim
140 words
The method as claimed in claim 1, wherein when the parity discrimination signal (PRT) is an odd parity, share (M1-M3) are M1=2, M2=M3=1 and the similar character discrimination signal (VAMB) is in a high potential or a low potential, a denary data 1 or 7 is outputted, when M1=1, M2=M3=2 and the similar character discrimination signal (VAMB) is in a high potential or a low potential, a denary data 2 or 8 is outputted, when M1=3, M2=2, a denary data 0 is outputted, when M1=2, M2=3, a denary data 9 is outputted, when M1=1, M2=3, a denary data 6 is outputted, when M1=3, M2=1, a denary data 3 is outputted, and in another case, a denary data 5 is outputted and the above data are transmitted through the transmitting/receiving unit (16) and an interface (17) to a host computer (18).
Claim 4
Dependent Claim
149 words
