Abstract
A piezoelectric scanning device comprises X-direction and Y-direction piezoelectric drive sections coupled to mutually perpendicular Z-direction piezoelectric clamping members. The selective application of voltages to the piezoelectric elements included in the X-direction and Y-direction drive sections and the Z-direction clamping members enables movement of the scanning device in two directions.
