ト印字ヘツド。[Claims for Utility Model Registration] A leaf spring supporting the armature at its tip to which the printing wire is fixed is attracted to the core by the magnetic flux of the permanent magnet and bent, and the coil attached to the core is energized to release the magnetic flux. In a dot printing head that performs printing with the wire by restoring the leaf spring by canceling out the above, the upper end of the core is formed to protrude in the horizontal direction,
A dot printing head characterized in that the point of attraction when the leaf spring is attracted to the core is close to the tip of the leaf spring.
