Abstract

A code scanning device for detecting an optical code on an object in a reading area, comprising a light transmitter for transmitting a reading beam, a deflection unit for periodically deflecting the reading beam over the reading area with a scanning frequency fscan, a light receiver for generating a received signal from the returning reading beam, a distance sensor for detecting a distance d from the object, and a control and evaluation unit configured to read a code content of the optical code on the basis of the received signal and to set the scanning frequency fscan as a function of the distance d.
