Abstract:
1. A drive apparatus, comprising: a first frame; a second frame supported movably in a first direction with respect to the first frame; a third frame supported movably in a second direction that intersects the first direction with respect to the second frame; a first drive mechanism provided between the first frame and the second frame, and configured to move the first frame and the second frame relative to each other; and a second drive mechanism provided between the second frame and the third frame, and configured to move the second frame and the third frame relative to each other, wherein each of the first drive mechanism and the second drive mechanism has a drive generator configured to generate drive with a piezoelectric element, and a drive receiver that is pressed relative to the drive generator and receives the drive generated by the drive generator, and the direction in which the drive generator acts on the drive receiver in the first drive mechanism is parallel and opposite to the direction in which the drive generator acts on the drive receiver in the second drive mechanism.
