Abstract (en)

[origin: DE19625767A1] The invention relates to a reader comprising a projection device for projecting of light emitted from a radiation source (117) to a section of a marked surface (20) and an optical unit (4) for receiving and visualising the reflected light on an image sensor (114) which transforms the reflected light into a sequence of electronic signals. The reader also has a motion detector (2) for generating synchronisation signals during movement parallel to the marked surface, and also a signal processing unit which converts the signals of the image sensor into information packets containing independently of the character code the alphanumerical, graphic or pictorial information of a freely selectable part of the marked surface, and stores said signals in a memory unit from which they can be retrieved.
