ABSTRACT:
A driving apparatus (100q) is provided with: a first base portion (110-1); a first stage portion (130-1); a first elastic portion (120-1) which has elasticity to displace the first stage portion in one direction (Y axis); a second stage portion (130-2) which is disposed on the first stage portion and on which a driven object (12) is mounted; a second elastic portion (120-2) which has elasticity to displace the second stage in other direction (X axis); a first applying device (151-1, 152-1, 22) for applying an excitation force for displacing the first stage portion such that the first stage portion is resonated in the one direction at a resonance frequency determined by the first stage portion and the first elastic portion; and a second applying device (151-2, 152-2, 22) for applying a driving force for displacing, in a stepwise manner or in a continuous manner, the second stage portion in the other direction.
