<P>PROBLEM TO BE SOLVED: To provide a printing method for bar-coding a large amount of information and expressing the bar-coded information in a small space. <P>SOLUTION: A plurality of circles different in radius and thickness of line are superposed to form concentric circles, and a bar code is formed by cutting them to make an aggregate of minor arcs of a central angle θ. The bar code is disposed at one end of a two-dimensional image. The minor arc is approximated by a rectangle or an approximate rectangle. The bar codes are adjacently arranged with alternately turning upside down. At least two patterns functioning as an index is arranged in the two-dimensional image. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
