ABSTRACT:
An actuator comprises a piezoelectric element and a mechanical amplifier. Displacement caused by the piezoelectric effect of the piezoelectric element is amplified mechanically by a lever-link system having a lever portion and a fulcrum. The lever-link system comprises multiple steps. The amplified displacement is effectively provided by a transmitting arm for use in a electronic equipment such as printers.
