Abstract

The invention relates to an optoelectronic code reader and to a method for the reading in of codes, which move relative to the code reader within a reading zone, by scanning the reading zone at least along one scan direction. For the reading of codes which are arranged along the scan direction at different distances to the code reader, at least one first scanning device and one second scanning device are provided which are controlled along the scan direction at different focal positions.
