Abstract:
1. A 4-state bar code printing system comprising: a bar code information acquiring section for acquiring or inputting a mail piece sorting information; an information recorded density enhancing section for evaluating a value of a character to produce values of bars, by using of a compression method depending upon a type of the information and digit, which are determined by the bar code information acquiring section; an input information encoding section for arranging the values of the bars produced by the information recorded density enhancing section in order of values of bars of the 4-state bar code, dividing the values of the bars into groups as a unit of three bars in order of the inputted information, and if the values is not divided into groups as a unit of three bars, adding the number of insufficient bars to the values, to allow the values of the bars to be a multiple of 3; an error correcting codeword producing section for producing an error correcting codeword by use of an Exclusive-OR bit operation method, based on the result of the information encoding section the input value of an error correcting level, of which a coefficient value of a index function is standardized; and a print frame producing section for arranging the error correcting codeword produced from the error correcting codeword producing section and the data produced from the information recorded density improving section in order of a start bar, a data, an error correcting codeword, and a stop bar, to print a 4-state bar code print font on a mail piece.
