Abstract
The spacing distance D between a scale and a scanner element of a scanner unit is adjusted simply through the use of a positioning element which is part of the scanning unit. The scanner unit has a mounting element on which the scanner element is supported. The scanner element is displaceable perpendicularly to a surface of the scale from a first reference position to a second reference position. A screw is used to actuate for the displacement and the reference positions are predetermined by stop faces of the screw and stop faces of the mounting element.
