Patent ID: 7843110

Claim:
A driving apparatus comprising: a stage portion which can be displaced; a first elastic portion whose one end is connected to the stage portion and which has elasticity to displace the stage portion in one direction; a driving source device, to which other end of the first elastic portion is connected, comprising: a first applying device for applying, to the other end of the first elastic portion, 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; a second elastic portion whose one end is connected to the driving source device and which has elasticity to displace the stage portion in the one direction; a third elastic portion whose one end is connected to other end of the second elastic portion 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.
