Abstract
A drive apparatus includes a first, a second, and a third frame, and a first and a second drive mechanism. The second frame is supported movably in a first direction with respect to the first frame. The third frame is supported movably in a second direction that intersects the first direction with respect to the second frame. The first drive mechanism is provided between the first and the second frames, and configured to move the first and the second frames relative to each other. The second drive mechanism is provided between the second and the third frames, and configured to move the second and the third frames relative to each other. Each of the first and second drive mechanism has a drive generator configured to generate drive with a piezoelectric element, and a drive receiver pressed relative to the drive generator and receive the drive generated by the drive generator.
