Abstract
A plurality of vertically aligned sensing members scan a matrix type bar code on a document. During the scanning of the bar code, the time period between the detection of succeeding bars is determined. An average time period which occurs during the detection of a number of bars is then generated. Each succeeding time period generated as a result of detecting the next bar is divided by the average time period to determine the presence or absence of the bar in addition to the number of spaces preceding the detected bar. This information is used in decoding the bar code label.
