ABSTRACT:
A print wire drive assembly for a dot-matrix printer having a plurality of solenoids selectively driving print wires. The solenoids are disposed, in plural groups which are not energized simultaneously, such that at least one solenoid of one group is disposed so adjacent to a solenoid of another group that the two solenoids are mutually inductive. The drive assembly comprises a solenoid drive circuit including first and second connection lines by which high- and low-level terminals of one of the two adjacent solenoids are connected to low- and high-level terminals of the other of the adjacent solenoids, respectively. At least one of the first and second connection lines includes a rectifying element which allows a current flow through the connection line in one direction from the low-level terminal to the high-level terminal when a reverse voltage is produced between the high- and low-level terminals of one of the adjacent solenoids upon deenergization thereof immediately before energization of the other solenoid.
