The device has two measuring units (14,18) that are attached to the respective mechanical elements (10,12). A unit (24,32) is provided in the former measuring unit for generating two light beams (28,30) that are emitted in same direction. The latter measuring unit has a reflector arrangement (38), which is arranged facing the former measuring unit for reflecting the light beams to a position-sensitive optical detector (36) of the former measuring unit. A surface (40) facing the former measuring unit is formed as a color separator. |
