。[Claims for Utility Model Registration] A spacer is provided adjacent to the leaf spring and forms a predetermined gap between the armature and the core,
The armature is attracted to the core by the magnetic flux of the permanent magnet and the leaf spring is bent. By energizing the coil, the magnetic flux of the permanent magnet is canceled and the armature is released. By doing so, the printing wire fixed to the tip of the armature is removed. A dot printing head that is driven, characterized in that the spacer includes a spacer spring portion that comes into contact with a flexible portion of a leaf spring, and the spacer spring portion has a spring function.
