Claims

[Claims for Utility Model Registration] 1. A printing head driving device 100 comprising a printing head 1, a carrier 2 supporting the printing head 1, and a driving means for driving the carrier 2, wherein the driving means comprises a first printer. an elastic body 31 having a plane and a second plane substantially perpendicular to the first plane; a first excitation body 32 that is attached to the first plane and excites vibration in one direction in the elastic body; a second excitation body 33 that is attached to a second plane and excites vibration in the other direction different from the one direction in the elastic body; and approximately elliptical vibration due to the combination of the vibration in the one direction and the vibration in the other direction. 1. A print head drive device characterized in that it comprises an ultrasonic vibrator 3 having a vibrating surface 34 on which a vibrating surface 34 is excited. 2. In the print head driving device 100 according to claim 1, the vibration in one direction excited in the elastic body is a bending vibration of the elastic body 31, and the vibration in the other direction is a stretching vibration of the elastic body 31. A print head drive device characterized by:
