ABSTRACT:
A wire dot print head having long thin print wires capable of axially advancing and withdrawing with respect to a print surface, and a wire driving device connected to the proximal end of each of the print wires so as to drive the print wire to advance and withdraw axially. The wire dot print head includes a distal end guide for guiding the distal end portions of the print wires so as to prevent them from shifting diametrically, and an intermediate guide for guiding portions of the print wires which are at an antinode in the secondary natural vibration mode of the print wires so as to prevent the print wires from oscillating diametrically.
