Abstract
Abstract A device for the precision displacement of an article within a plane in which two piezoelectric plates are arranged in one plane, each plane being connected, with its end, to a coordinate table by means of a corresponding flat spring, with its other end being rigidly secured onto a platform, and a piezoelectric plate for turning the coordinate table within the plane, with the latter plate being connected to the platform by means of a screw pair.
