Abstract
A bar code reading apparatus for detecting the space between characters (the character space) by counting the number, which is a fixed number in the bar code, of edges, or transition points, of the bars and spaces for each character code, and either inhibits the count value by its bar/space width counter for the space beyond the fixed number of bars/spaces for one character (i.e., the count value for the character space) from being supplied to its decoder portion, or supplies the decoder portion with a specific code which the decoder will neglect in decoding, whereby the character space is prevented from adversely affecting the bar code reading.
