Abstract
A code reader for reading one- and/or two-dimensional codes. A position resolving light receiver () is mounted in a housing (). An imaging optics made of several components is associated with the light receiver and is also disposed in the housing. The imaging optics has at least one stationary optics () and a deflecting optics arranged on an optical axis () in front of the light receiver (). A pivot arm is mounted on a pivot axis () in the housing. Pivoting of the pivot arm results in a positional and angular change of the effective back optical focal distance measured from the vortex of the last back surface of the lens to the focal point thereof. If the objects to be identified are at different distances from the identification apparatus, the pivot arm () is pivoted. As a result, the deflection optics mounted on the pivot arm changes the effective back focal distance as well as the focal length of the imaging optics to thereby project an exact image onto the light receiver.
