Document Type and Number:
WIPO Patent Application WO/2004/003930
Kind Code:
A1
Abstract:
A feeder for feeding a movable piece (27) by driving legs (21 and 22) having an expansion−contraction deformation unit (23) and a shear deformation unit (24). A high−speed operation of the feeder is realized and the average voltage is set to almost zero by applying sinusoidal drive voltages to expansion−contraction deformation unit (23) and the shear deformation unit (24) of the driving legs (21 and 22).
