  • Vibrator-type actuator
    Patent number: 5130599
    Abstract: An actuator includes a pillar shaped ceramic piezoelectric body, a pair of electrodes formed on both base surfaces of the piezoelectric body, and a moving element made to contact with the side surface of the piezoelectric body in the longitudinal direction. A sheet provided in the longitudinal direction between two piezoelectric bodies is moved by driving the piezoelectric bodies. A roller is made to contact with the side of the piezoelectric body and a paper is pressed against the roller for feeding the paper. The side surface in the longitudinal direction of the foregoing piezoelectric body can alternatively be made to contact with the surface of a rail which guides the piezoelectric body movement.
