<p>A drive device (100q) comprises a first base portion (110-1), a first stage portion (130-1), first elastic portions (120-1) having elasticity allowing the first stage portion to move along one direction (Y-axis), a second stage portion (130-2) which is provided on the first stage portion and on which objects to be driven (12) are mounted, second elastic portions (120-2) having elasticity allowing the second stage portion to move along a different direction (X-axis), first applying portions (151-1, 152-1, 22) for applying excitation force to move the first stage portion in such a manner that the first stage portion resonates along the one direction at a resonant frequency determined by the first stage portion and the first elastic portions, and second applying portions (151-2, 152-2, 22) for applying driving force to move the second stage portion stepwise or continuously along the different direction.</p> |
