Abstract
The multi-wire dot print head is provided with a plurality of print wires with a wire driving armature associated with each of the print wires and being operable to move the print wire toward a print position. The wire driving armatures each include an actuator lever and a cylindrical movable core mounted intermediate opposite ends of the actuator lever with an electromagnetic actuator associated with each of the armatures for imparting movement thereto. The outer end of the actuator lever is provided with a downwardly depending pivot leg and pivot or fulcrum support means for the actuator lever is positioned in a plane below the level of the open end of a cylindrical bore in the electromagnetic actuator so that a minimum amount of clearance may be provided between the cylindrical core and the cylindrical bore.
