BAR CODE DECODING APPARATUS AND METHOD

摘要

An apparatus and method for decoding data read from any one of a plurality of different types of bar code labels includes circuit means (66,172,186,194) for detecting the occurrence of two equal continuous characters in the data generated by an optical scanner (31) in reading a bar code label and a filter (38,40,42) for each of the different bar code labels receiving simultaneously the two equal characters for decoding the character data and inserting locating bits in the data delimiting valid characters in the data.
