In the absolute measurement of the position of an object (10) over a plurality of cyclical scannings performed on a material measure, a coding unit (18) is employed to record the cycles. The coding unit (18) is coupled to the measured object (10) by an effective mechanical link (22, 24). The effective link consists of a driving gearwheel (22) and a driven input wheel (24), which belongs to the coding unit (18). To minimize wear on the toothed connection, the connection is allowed a large degree of play and the driven input wheel (24) is run by a motor (26) synchronously with the drive gearwheel (22), as controlled by the scanner (12). The result is that the effective connection occurs within the area of play, without mechanical engagement of the toothings.
A device for the absolute measurement of the linear or rotary position of an object, with a material measure which is coupled to the measured object (10) and is scanned cyclically by a scanner (12), and with a coding unit (18) which records the position of the material measure over a plurality of scanned cycles, such that the coding unit (18) exhibits an input wheel (24) which is coupled to the measured object (10) by an effective mechanical link,
