Abstract
A bar code reading apparatus including a reader for reading a bar code expressing a plurality of characters, and a CPU for decoding the characters according to a result of reading by the reader. A ratio between a character length C of an already decoded character E and a length C of a character E to be decoded is calculated. When this ratio is greater than a threshold value, the black bar width B and black bar width B are corrected according to a reference black bar width X. The CPU decodes the character E to be decoded according to the corrected black bar width B and black bar width B .
