Claims

[Scope of Claim for Utility Model Registration] 1. An armature to which a printing wire is fixed is mounted on a plurality of divided pieces formed on a leaf spring, a yoke is arranged on the top of the leaf spring, and the divided pieces are driven by the magnetic flux of a permanent magnet. Leave it biased,
In a wire dot print head that drives a print wire by selectively exciting an electromagnet formed by a core and a coil to eliminate or create a magnetic flux of a permanent magnet to bias or eliminate the bias of a leaf spring, a divided piece of the leaf spring is used. A wire dot print head characterized in that a hollow part is formed in the hollow part, and a joint and a plate are formed in the hollow part. 2. A wire dot print head according to claim 1 of the utility model registration, characterized in that a yoke is supported and fixed slightly inside the center of rotation of the divided pieces of the leaf spring.
