A bar code recognition apparatus comprises a manual scanner for reading each code bar, a comparison circuit for comparing a width value detection signal to a reference value to produce a width value amplitude comparison signal, a ratio circuit for making a ratio between one and another of said width value detection signals to produce a ratio signal, and a character decoder for decoding the comparison signal and the ratio signal. Accordingly, one character output is provided corresponding to the width value detection signal of a detected code bar.
