PURPOSE:To increase the information amount of a barcode with a limited area. CONSTITUTION:An endless barcode 1 is generated by combining the line kinds of the lines with which division is executed between two concentric circles with different diameters by at least a five-degree dividing method or different line length with the concentric circles as reference and ultraviolet ray reflection ink is used for the lines with which division is executed. The endless barcode is generated by combining the line kinds of the line with which division is executed between two polymn. long-sidway ellipses with different diameters by at least the five-degree dividing method or different line length with the ellipses as reference. Moreover, the endless barcode is generated by combining the line kinds of the line with which division is executed between two polymn. shapes with different areas by at least the five-degree dividing method or different line length with the polymn. shapes as reference. |
