PRINTING HEAD OF WIRE-DOT IMPACT PRINTER A printing head includes a plurality of impact printing wires constituting a dot matrix and a plurality of actuators for driving the printing members, respectively. Each of the actuators comprises a movable member to which a printing wires is connected, and electro-distortion device, a pair of parallel resilient members having one ends connected, via an electrodistortion device and directly, respectively, to the frame and the other end connected to the movable member, so that a displacement of the electro-distortion device is enlarged by the movable member and transmitted to the printing wire. A third resilient member is arranged substantially perpendicular to the first and second resilient members to connect the movable member to the frame. |
