More Information
Summary:An apparatus for driving a printing head of a wire-dot printer, the apparatus including a plurality of electroexpansive elements (2) for driving respective printing wire (4) cooperatively constituting a wire-dot matrix. The electroexpansive element (2) is expanded and shrunk by an electrical charge/discharge, to move the printing wire (4). The times for the charge T1 and discharge T2 are: in the case of continuous dots, T1 = A, T2 = B' for the first dot, T1 = A', T2 = B' for later dots, and T1 = A', T2 = B for the last dot, and in the case of a single dot, T1 = A, T2 = B, provided that A > A', and B > B'.
