SYSTEM FOR PRINTING AND READING 4-STATE BARCODE AND CONTROLLING METHOD THEREOF

摘要

PURPOSE: A system for printing and reading a 4-state barcode and a controlling method thereof are provided to effectively carry out the postal service by improving the reading for an automatic postal matter classification process and the barcode information acquirement of a customer. CONSTITUTION: A barcode information acquirer acquires and inputs the customer recognition information, the article information and the postal matter classification information, and stores and judges the postal matter classification information(101,102). An information density enhancer generates a value of a bar by finding out a character value through the application of a compression method according to an information type and a cipher(103). An input information encoder arranges the value in an order of a bar value of the 4-state barcode(104). An error correction code word generator generates an error code word by an exclusive-OR bit operation method standardized by a coefficient value of an exponent function(105). A print frame generator prints a 4-state barcode font on the postal matter by arranging a start bar, the data generated by the information density enhancer, the error correction code word and a stop bar(107).
