Patent ID: 7834519

Claim:
A precise and high load resistance moving method comprising: (a) fixing a first piezoelectric element which generates a shear deformation, to a bottom surface of a wedge-shaped moving element which is placed on a base having wall surfaces to both sides and has a triangular shape having two inclined surfaces on the upper side in a cross section, and fixing second and third piezoelectric elements which generate shear deformations in a depth direction of the page surface to each upper inclined surface of both sides of the wedge-shaped moving element, and (b) moving the wedge-shaped moving element is laterally moved on the base by rapidly deforming and driving the first piezoelectric element, and striking or extracting the wedge-shaped moving element to/from two moving bodies movable in a vertical direction to the base and in a depth direction to the page surface, whereby a fine movement positioning of the moving bodies in the vertical direction is performed so that a total of potential energy of the two moving bodies in the vertical direction is not changed, and, by rapidly deforming and driving the second and third piezoelectric elements, whereby a fine movement positioning of the moving bodies in the depth direction of the page surface is also performed.
