摘要： A device for positioning a measuring element is provided in which the measuring element is suspended by two parallelogram linkage systems in a pivotable manner, the parallelogram linkage systems being arranged at an angle relative to one another. Each lever of the parallelogram linkage systems is provided with a ball joint and is drivingly connected via the ball joint to a respective threaded spindle. The threaded spindles are drivable by a reversible stationary stepping motor. With this arrangement it is possible for the measuring element to perform planar and circular movements in addition to the commonly performed pivoting movements. Furthermore, an adjustment of the pivoting point is possible, and each individual lever of the parallelogram linkage system may be adjusted individually.
