CODABAR LABEL READER |
摘要 |
<p>Title "CODABAR" LABEL READER A method for reading bar-coded labels by taking ratios of successive bars and spaces, then discriminating and categorizing the ratios of one of four possibilities. This output is combined and decoded into characters using a read-only-memory. The characters along with information on spacing between the characters is then passed to a microprocessor. The microprocessor decides which of the characters are valid and assembles a complete scans worth of information by making use of the data relating to the separation between characters. Handling the data in this fashion provides a means to assemble data from partial scans of the label into one complete scan. RD-3046</p> |
