Stage utilizing ultrasonic motor and printer utilizing the stage

摘要

It is an object to improve positioning accuracy and to provide a simple and compact mechanism which can be used in an environment where magnetization is avoided. A stage including a first moving body which is movable in one direction and a second moving body which moves in one direction with said first moving body and which is movable in another direction different from said one direction, comprising: a first piezoelectric actuator or ultrasonic motor which is put in contact with said first moving body for moving the moving body in said one direction; and a second piezoelectric actuator or ultrasonic motor which is put in contact with said second moving body for moving the moving body in said other direction. <IMAGE>
