Abstract
The invention discloses a six-coding element article bar code. The invention belongs to an improved EAN-13 bar code, and relates to a one-dimensional code field. The object of the invention is to provide the improved EAN-13 bar code, and by adopting the improved EAN-13 bar code, accuracy of automatic identification of photoelectric equipment is higher. In order to achieve the above mentioned object, coding rules of ten numeric characters are changed; from original eight coding elements into six coding elements, namely, bar, bar bar, bar bar bar, null, null null, null null null, and the left and right width of every numeric character is only five units, and in addition, an arrangement structure is (odd integer position) two bars and one null (even integer position) one bar and two nulls, or, (odd integer position) one bar and two nulls (even integer position) two bars and one null. The six-coding element article bar code is advantageous in that the accuracy of the automatic identification of the photoelectric equipment is higher.
Description
technical field [0001] The invention relates to the field of one-dimensional barcodes, in particular, it belongs to an EAN-13 barcode. Background technique [0002] Item barcodes include one-dimensional barcodes and two-dimensional barcodes, as well as three-dimensional barcodes for new technologies in the future. This invention only involves one-dimensional barcodes, and only the most popular and universal one-dimensional item barcodes --- EAN-13 item barcodes . [0003] The EAN-13 article barcode is a relatively mature article barcode that has been used for decades. But everything has two sides, and its mature and reliable backside also has the disadvantage that the coding width is not short enough. [0004] The coding left and right width of each numeric character in the EAN-13 article barcode is 7 units, and the total left and right width of 12 numeric characters is 84 units. If the EAN-13 item barcode is improved and the left and right width of each numeric character...
