ABSTRACT:
A mechanical amplifier for a piezoelectric actuator employs a lever-link system having a lever and a fulcrum to amplify a displacement caused by the piezoelectric effect of the piezoelectric element. A fulcrum supporting a last amplified lever forms a semi-pivotal construction to strengthen the stiffness of the amplifier. The invention converts electrical energy into mechanical energy for application to a printer or other electronic instruments.
