摘要：
A bar code reading method deals, as valid data, with demodulated data obtained by synthesizing demodulated data obtained by reading a first data block A of an upper stage of a bar code (having two column codes structured by arranging WPC codes up and down in two columns) with demodulated data obtained by reading a second data block B of the upper stage, and demodulated data obtained by synthesizing demodulated data obtained by reading a first data block C of a lower stage of the bar code with demodulated data obtained by reading a second data block D of the lower stage, only if both of the demodulated data obtained by reading the first data block A of the upper stage and the demodulated data obtained by reading the first data block C of the lower stage, contain a portion corresponding to data characters of the second data block (B, D), and further only if these sets of demodulated data are different from each other.
