Abstract
A print head for use in dot matrix printers for producing characters and symbols formed from dots. The print head is composed of a plurality of stylus actuator assemblies arranged one after the other in two interlocking rows and with all the styli level with each other on a head frame. Each of the stylus actuator assemblies comprises an electromagnetic actuator fixed to the head frame and energized by an impact driving current, a yoke base fixed to the stylus actuator assembly, and an armature pivotally supported on the yoke base and at one end thereof having a stylus for printing and at the other end thereof having a plunger attracted by the electromagnetic actuator, whereby the stylus is impacted onto a recording paper. All armatures of the stylus actuator assemblies have bent portions provided on the same side thereof with respect to the direction in which the print head traverses.
