ABSTRACT:
A demodulated data storage buffer is stored with bar width data sets obtained by scanning a coupon code with a scan optical system. A CPU first executes a demodulating process on these bar width data sets in accordance with a demodulation algorithm in a WPC code system. If an end guard bar (RGB) of the WPC code is contained in the demodulated data by the demodulating process, the demodulating process is executed on the same bar width data sets in accordance with a demodulation algorithm in a CODE 128 code system.
