发明名称 BAR CODE ENCODING SYSTEM USING FOUR-STATE CODES
摘要 A bar code encoding system comprising a representing unit for representing an input character by an information symbol of m bits excluding a bit pattern of all "0" bits, a calculating unit for subjecting a series of a k-number of information symbols to error-correction encoding and calculating a check symbol series of a q-number of check symbols, a converting unit for respectively converting an n=(k+q) number of symbols to predetermined bar code patterns, and arrangement converting unit for converting arrangement of the n-number of symbols so that at most three bar code patterns corresponding to the check symbols may not be consecutively arranged.
