摘要： This invention is related to a system and a method for reading high precision printed barcodes and their specification verification. The presented invention has a technique of reading both logistic sorting barcode (one or two dimension) and multi-layered structure barcode such as four-state barcode for automatic postal matter sorting. The invention also investigates height of high densely reduced barcodes in more than 3 steps, and precisely measures and reads the values of black bars thickness and white spaces. Previous techniques used laser beam for reading barcodes, but could not read barcodes, which have print density of less than 1/100 mm˜1/1,000 mm unit, and, it was also impossible to read precise specification values in case that barcode specification was composed of length unit indexes. The presented invention overcomes the previous said problems by using a laser diode array.

摘要： A system and a method for automatic mail operation with four state barcode are provided. An automatic mail operation processing system with four state barcode in accordance with the present invention includes customer barcode supporting system, mail operation supporting system, and automatic sorting system. The customer barcode supporting system converts information into four state barcode and prints the barcode on mail and mail receiving form when a customer supplies the information. The information is necessary for shipping the mail. The mail operation supporting system receives the mail and the mail receiving form, determines postal fee, and reports result of receipt to the customer through the customer barcode supporting system. The automatic sorting system reads the four state barcode on the mail and sorts the mail automatically.
