Abstract
A method and an apparatus are set forth for the reading of a bar code consisting of a predetermined number of code elements in which a bar code reader which scans the code elements generates a binary signal with sequential high-low phases, the lengths of which correspond to the widths of the sequentially scanned code elements. Only those high-low phases whose lengths lie within a defined region are processed further as permissible code elements. Permissible code elements belonging to directly sequential high-low phases are respectively grouped into segments, and only those segments are processed further as being permissible which have at least the predetermined number of code elements. If the number of code elements of a permissible segment exceeds the predetermined number, the code elements which actually belong to the bar code to be found are determined by a start marking, a stop marking and/or a center marking contained in the segment and the bar code which has been found is decoded.
