发明名称 Position-measuring device
摘要 A position-measuring device for measuring linear and/or angular positions includes at least two measuring standards on which at least one code track is applied, and includes a scanning unit for scanning the code tracks. The measuring standards are positioned with respect to each other such that at least one code track of a first measuring standard and at least one code track of a second measuring standard at least partially overlap and the position information of at least one of the code tracks is scannable by the scanning unit in the region of overlap.
