ド。[Scope of Claim for Utility Model Registration] 1. An armature to which a printed wire is fixed is mounted on a split piece of a leaf spring, and the biasing and unbiasing of the split piece is performed by an electromagnetic part with a core having a permanent magnet and a coil. A wire dot print head for driving printing by a print wire, characterized in that a hole slightly larger than the core is formed in the split piece of the plate so that the core can directly attract the armature. 2. A wire dot print head characterized in that the leaf spring according to claim 1 is made of a non-magnetic material.
