Patent ID: 6945045

Claim:
A driving apparatus, comprising: a shape memory alloy member connected to a movable member; and an electric supplier for heating the shape memory alloy member by applying a voltage or current thereto, the supplier making the shape memory alloy member expand and contract, through generation of heat based on the application by the supplier and through dissipation of heat therefrom resulting from suspension of the application by the supplier, so as to drive the movable member to move, wherein the shape memory alloy member is configured to operate at a temperature of 70° C. or higher, and the driving apparatus is for driving a hand shake correction apparatus and includes an actuator that is controlled by a servo and whose temperature is controlled continuously, the driving apparatus further comprising: a loading mechanism for loading the movable member with a force that acts in the direction opposite to that exerted by the shape memory alloy, wherein by operating the shape memory alloy at a temperature of 70° C. or higher, hand shake by the hand shake correction apparatus can be corrected.
