ABSTRACT:
When bar code data of a left or right block flanked by a guard bar and a center bar is input, several characters including the first character are demodulated, and a decision is made as to whether demodulation should be continued or not. If demodulation has already been performed a specified number of times, or demodulation free from significant distortion has already been performed, on the block currently subjected to demodulation, the demodulation process is discontinued and demodulation is not performed on the remaining characters.
