Claims

[Claims for Utility Model Registration] 1. Printing by a dot printer having a plurality of adjacent piezoelectric elements having substantially rectangular cross sections arranged in a ring shape, and two lead wires for supplying voltage to each piezoelectric element. In the head, one lead wire connection portion to the piezoelectric element is provided at the center width portion of two of the four sides having a rectangular cross section to prevent the connection portions of adjacent piezoelectric elements from coming into contact with each other. Print head of dot printer. 2. A printing head for a dot printer according to claim 1, characterized in that the connecting portions are provided offset from each other in the longitudinal direction of the piezoelectric element.
