ABSTRACT:
A system for reading coded characters, in particular characters coded in the CMC7 code, includes at least one reading head, two threshold switching circuits which receive output signal from the reading head, two recognition channels which receive signals from the two threshold switching circuits, a multiplexer MX which enables either one or other of groups of outputs from the two recognition channles to be selected, and error detecting circuits which control the position of the multiplexer MX to enable certain reading errors to be corrected automatically.
