摘要

PCT No. PCT/EP96/05078 Sec. 371 Date Jun. 26, 1997 Sec. 102(e) Date Jun. 26, 1997 PCT Filed Nov. 18, 1996 PCT Pub. No. WO97/19324 PCT Pub. Date May 29, 1997In a length measurement device for measuring the relative position of two objects in which a scale is connected with one object via retaining elements and the ruling of the scale is sensed by a sensing unit formed of a measurement head and a measurement carriage, wherein the sensing unit is coupled to the other object via a coupling point by drivers which are constructed as a deflectable, elastic coupling device. The coupling device is fastened to the measurement carriage at two connection locations, wherein the coupling point is arranged between these connection locations for coupling the sensing unit to the other object.
