摘要

A method of and an apparatus for reading a bar code, in which a plurality of types of bar codes which may coexist can be demodulated with higher accuracy and higher speed, are disclosed. A bar code data detector (31) extracts the features of a guard bar and a center bar. This information is searched for by a search section (39a) and the features and the bar code types read are identified. The bar code data are demodulated in a bar code demodulator (32) by a method corresponding to the result of identification of the features and the bar code types. <IMAGE>
