ABSTRACT:
A CPU demodulates data obtained by a "continuous reading", data obtained by a "block reading" and data obtained by a "divided reading" among a variety of bar width data sets stored in a bar width data set storage buffer before demodulated data corresponding to a whole bar code are first synthesized. Once the demodulated data corresponding to the whole bar code are synthesized, whether the data used for the synthesization include the data obtained by the "divided reading" is checked. Then, if the data used for the synthesization do not include the data obtained by the "divided reading", only the data obtained by the "continuous reading" and the data obtained by the "block reading" are demodulated.
