Patent ID: 7843108

Claim:
A driving apparatus comprising: a stage portion which can be displaced; two first elastic portions whose one ends are connected to the stage portion and which have elasticity to displace the stage portion in one direction; two driving source portions each of which comprises: a first applying device for applying, to other ends of the first elastic portions, an excitation force for displacing the stage portion such that the stage portion is resonated in the one direction at a resonance frequency determined by the stage portion and the first elastic portion; and a second applying device for applying a driving force for displacing, in a stepwise manner or in a continuous manner, the stage portion in other direction which is substantially perpendicular to the one direction, the other ends of the first elastic portions being connected to the respective two driving source portions; two second elastic portions whose one ends are connected to the respective driving source portions and which have elasticity to displace the stage portion in the one direction; a third elastic portion whose one end is connected to other ends of the second elastic portions and which has elasticity to displace the stage portion in the other direction; and a base portion to which other end of the third elastic portion is connected, the driving apparatus shifting at least one of a direction and a phase of the excitation force applied by each of the two driving source portions.
