ABSTRACT:
A detecting and decoding circuit detects and decodes a multiple-row bar code consisting of n rows, each of which has a left block and a right block. A bar code data editing circuit extracts one bar code data a decoded signal received from the detecting and decoding circuit and performs a modulo 10 check for the bar code data. In addition, a determination circuit receives the edited result of the bar code data editing circuit and determines whether or not the number of each of right block data and left block data is n, whether or not the number of valid data in the modulo 10 check is n, whether or not the number of sequence data is n-1, and whether or not any two data of each of the left block data and the right block data are not the same as each other, and for outputting a reading valid signal when all these conditions are satisfied.
