This paper deals with cluster feeding mechanism using loop type resonator's train. The resonator consists of loop and leg part, respectively. Each part was actuated by bimorph type piezoelectric members. The deflection of loop part and the bending of leg part generated by piezoelectric bimorphs makes an elliptic motion at the center point of the upper member. If resonators are put in a train and are actuated at the same frequency, it can feed objects on the upper surface of its train. The trial feeder, we developed, consists of 8 resonators (4 resonator pair). It could generate elliptic motion in arbitrary phase and could feed thin or soft objects that could not be fed with usual feeders. The feeding speed, that is obtained by dividing the feeding distance at the feeding time with camera vision, changed by phase shift of the input to leg part (z) with the input to loop part (y). The principle of feeding with the cluster feeder was clarified, and it was shown that the theoretical feeding speed fairly agree with the experimental ones. The cluster feeder can feed a thin or a soft object without damaging.
