<P>PROBLEM TO BE SOLVED: To attain a drive device that is capable of accurate positioning and proper controllability, has small power consumption, and is abundant in reliability, and has a small and simple structure. <P>SOLUTION: The drive device has an operation part, an elastic member, whose one end is fixedly provided to the operation part and whose the other end is fixedly provided to a support member, and a piezoelectric actuator whose one end is fixedly provided to the operation part and whose the other end is fixedly provided to the support member. The operating member is operated in a first direction due to a displacement of the piezoelectric actuator. The rigidity of the elastic member in the first direction is lower than that of in the direction that is orthogonal to the first direction. <P>COPYRIGHT: (C)2008,JPO&INPIT |
