ABSTRACT:
A stylus actuator unit for dot matrix line printers in which each electromagnetic actuator drives each stylus.
An armature is rockably supported by the electromagnetic actuator while fixing a stylus for printing to one end thereof and having at the other end thereof a plunger to be attracted by the electromagnetic actuator. At an intermediate between the stylus fixing end and the plunger fixing end of armature is provided an armature support member composed of a torison leaf spring which is supported by a yoke base mounted on the electromagnetic actuator.
The torsion leaf spring has a configuration of the letter E and both side portions are fixed to the yoke base and the central portion supports the armature. When the electromagnetic actuator attracts the plunger, the armature on the side of the stylus is driven in the opposite direction to the direction of attraction, thereby enabling the stylus to impact to the paper placed over the outer periphery of the platen.
