ABSTRACT:
An armature support device for rotatably supporting, in a print head, one end of an armature which holds a print wire at the other end thereof. The support device comprises a support member and a spring member. The spring member is made of a piece of a resilient wire, including a fixed portion of a hair pin shape to be secured to the armature, a pair of arm portions extending oppositely on the same axis from both ends of the fixed portion for functioning as a rotational fulcrum for the armature, a pair of leg portions further extending, by being perpendicularly bent, from both ends of the arm portions for being firmly fixed to the support member. The armature is biased toward a predetermined position by torsional resilient force of the arm portions of the spring member, and it is rotated about the arm portions by an electromagnetic device twisting the same to advance or restore the print wire.
