摘要：
This invention is intended to contribute to improvements of the reading accuracy of a bar code reader and performance of a POS system or the like. To attain this object, according to the invention, when one of the data blocks constituting a bar code cannot be detected, addresses of the non-detected data block are determined based on a width of the detected data block and addresses of the center bar. The invention is constituted such that data of the previously non-detected data block is detected based on its addresses.
