This study describes sheet feeding method and its design concept using ultrasonic vibration actuator. The ultrasonic vibration is generated bv two sets of piezoelectric actuator. It is an elliptic vibration mode, which rotates two vibtaton modes in the Y-Z and X-Y planes. This paper presents a direct drive method using vibratory rotor and an indirect drive method using idling rotor about sheet feeding mechanism, and proves theoretical relations between amplitude U_<Z1> and sheet feeding speed V_H, V_H^* and feeding force F_H, F_H^*. As a result of fundamental experiments, it was proved that a sheet, such as paper and telephone card, could be fed easily using either of their methods, and high reliable and compact sheet feeding mechanism could be obtained.
