Abstract
The printing head for a wire-type dot printer includes a plurality of electromagnetic coils, a wire, a permanent magnet, and a leaf spring. The arrangement of the wire and the leaf spring allows the print head to operate stably during high-speed operation. The wire dot print head has a head body in which the wire drive units are assembled so there is no problem with magnetic interference between the electromagnets. In addition, the wire dot print head may be comprised of a multiplicity of wires, and may be of a double-deck construction type which renders the unit more compact. This arrangement allows the construction of a multiwire high speed print head which can be easily assembled from simple parts.
