<p>A drive device (100a) comprises a base portion (110), a movable stage portion (130) on which objects (12) to be driven are mounted, elastic portions (120) connecting the base portion and the stage portion and having elasticity allowing the stage portion to move along one direction (Y-axis), and applying portions (141, 142, 22) for intermittently applying excitation force to move the stage portion in such a manner that the stage portion resonates along the one direction at a resonant frequency determined by the stage portion and the elastic portions. The excitation force is caused by a piezoelectric effect.</p> |
