Abstract: A position-measuring device includes a scale having first and second measuring graduations, which each include graduation structures that respectively extend parallel to first and second directions. A first scanning unit is associated with the first measuring graduation, and second and third scanning units are associated with the second measuring graduation. A fourth scanning unit is associated with the first or second measuring graduation. In the former case, a first straight connecting line running through scanning locations of the first and fourth scanning units and a second straight connecting line running through scanning locations of the second and third scanning units are parallel or form a predetermined angle therebetween that is not equal to a sum of the angles of the first and second directions. In the latter case, the scanning locations of the second, third and fourth scanning units do not lie on a common straight connecting line.

Abstract: A position-measuring device includes a carrier body and scanning units movable relative thereto. At least three surfaces of the carrier body each carry a first and second measuring graduation, each having a series of graduation lines. Each of the measuring graduations is associated with a scanning unit for scanning the respective measuring graduation at a scanning location such that, for each surface, two scanning units are disposed for scanning the respective measuring graduations. In each case, these two scanning units are disposed in such a way, and the graduation lines of the two measuring graduations are inclined with respect to each other in such a way, that two normal planes extending respectively in the direction of the respective graduation lines through the respective scanning locations of the two scanning units have a common axis of intersection, whereby the three resulting axes of intersection extend through a common point.
