ABSTRACT:
There is disclosed a bar code processing system in which a plurality of vertically aligned sensing devices are positioned adjacent a moving document on which is located a plurality of dot matrix printed coded bars. Each of the sensing devices is positioned so as to sense one of the matrix dots which form the coded bar and output an analog signal whose signal level varies directly in accordance with the ink intensity of the sensed dot. Signals are then amplified, filtered and converted to digital signals which are then examined. If a predetermined number of dots in the bar have been sensed and of the dots sense, no more than two dots are found to be separated by more than one blank space where a dot would normally be located, a signal is generated indicating that a valid bar has been sensed. These signals are then used in decoding the bars sensed.
