<p>Realized is a code system wherein a color sequence usable as an optical automatic recognition code representing data by means of the order of colors is continuously marked on an article such as a cord and the same correct data can be read even if any cell of the color sequence is started to be read. The color sequence (code symbol) is determined so that cyclic codes of the color sequence also represent the same data. The cyclic codes are color sequences determined by shifting (rotating) the code symbol in such a way that the cells are cyclic. When a color sequence is composed of six cells, five cyclic codes are determined from the color sequence. Since six color sequences in total represent the same data, the data can be correctly read even if any cell is started to be read when the color sequences are continuously marked.</p> |
