ABSTRACT:
A bar code is constructed from individual characters that are laid out along a first straight line. Each character is formed by a series of bars and spaces that are parallel to the first straight line and that are laid out along a second straight line which is perpendicular to the first straight line and which passes through the center of the character. The resulting bar code is scanned manually by an operator who propels a hand-held scanner across the bar code in a direction parallel to the first straight line. The hand-held scanner contains a linear photodetector array mounted opposite optical elements in such a manner that a line image of a bar code character roughly perpendicular to the first straight line is projected upon the linear array as the stylus passes over a character. As the bar code is manually scanned, the linear array scans through each bar-coded character at numerous points and thereby generates numerous sets of digital data each representing the width of the successive bar and space regions which comprise each character. The resultant digital data is filtered, decoded and error-checked. When a series of consecutive scans over a given character result in the detection of identical error-free data, that data is accepted as a proper representation of the given character and is forwarded to a data capturing device. The scanning then commences to look for bar space patterns indicating that the scanning has progressed to the region which separates adjoining characters from each other. Then the scanning for data recommences. In this manner, a single pass of the hand-held scanner over the bar code results in the accurate capture of the data represented by the code without the necessity of multiple passes over the ticket.
