Abstract

PURPOSE:To perform reading operation with an extremely low misreading rate, by providing a check digit discrimination part, composed of a microcomputer, in an intermediate processing part. CONSTITUTION:An optical input signal inputted by scanning data on read data 2 to be scanned is inputted to a data processing part 5 through a character discrimination processing part 4. A check digit discrimination part 6 is connected to the data processing part 5, which checks whether the read data is correct or not by a check-digit system modulus 10. Namely, each digit of the read data is weighted to find the total, which is checked by arithmetic; when a difference 4 obtained by subtracting the total from a numeral at the tens position higher than the total is coincident with the numeral 4 of a check digit 9, a correct read is discriminated to output the read data to a host processor 7.
