Code reading learning system

摘要

PROBLEM TO BE SOLVED: To provide a code reading learning system configured to simply improve read efficiency, in accordance with a use environment, to improve work efficiency.SOLUTION: A learning section 25 compares teacher data, which is a reference value of a decoding threshold for decoding a bar-code, with data on spaces and bars extracted by an extraction section 23, to calculate a difference between corresponding data. The reference value of the decoding threshold is updated so as to reduce the difference.SELECTED DRAWING: Figure 2
