ABSTRACT:
A linear motor driving device includes a pair of actuators each having a first piezoelectric element, a pair of levers connected to the first piezoelectric element, and an apparatus for magnifying the displacement caused by the first piezoelectric element. A second piezoelectric element is connected to the pair of actuators. The second piezoelectric element translates the levers in a direction perpendicular to the direction of actuation of the levers.
