Abstract
A method of reading of a bar code consisting of a predetermined number of code elements for the generation of a binary signal with sequential high/low phases, the length of which correspond to the widths of the sequential code elements. The bar code is sensed by at least two scanning beams from different directions along different scanning lines. At least some of the regions of the bar code are scanned by a scanning beam and are respectively detected as a code segment, and wherein at least some of the detected code segments are selected with respect to predetermined decision criteria and combined for the reconstruction of the scanned bar code. Furthermore an apparatus is described for carrying out the method.
