Abstract

This paper describes sheet feeding method and its design concept using the ultrasonic vibration actuator. The ultrasonic vibration is generated by two sets of piezoelectric actuators. It is an elliptic vibration mode, which rotates two vibration modes in the Y-Z and X-Y planes. This paper also presents a direct drive method using vibratory rotor and an indirect drive method using the idling rotor about sheet feeding mechanism, and it verifies theoretical relations between amplitude UZ1 and sheet feeding speed VH ,VH* and feeding force FH ,FH*. As a result of fundamental experiments, it was proved that a sheet, such as paper and telephone card, could be easily fed using either of their methods and a the highly reliable and compact sheet feeding mechanism could be obtained.
