ABSTRACT:
A bar code reader decodes a bar code in different directions if the bar code contains special characters whose bar widths have been corrected. The bar code reader compares the decoded results in the different directions with each other, to improve the bar code reading reliability. If the decoded results agree with each other, the results are accepted, and if not, they are discarded.
