Abstract

The invention relates to a scanner device having a mirror arranged so as to be pivotable about an axis of rotation, an iron core with an air gap, a coil arranged about a portion of the iron core, and two permanent magnets. The two magnets have differently directed magnetizations and are arranged inside the air gap at different angular rotation positions with respect to the axis of rotation. An armature made of a soft-magnetic material is arranged on the mirror in such a manner that the armature is residing inside the air gap and, by means of application of electric current to the coil, the armature is moved toward one of the two magnets, depending on the direction of the current, and the mirror rotates.
