ト印字ヘッド。An armature having a dot wire at the tip is arranged on the lower center surface of the tongue piece of a leaf spring, which has an H-shaped slit in the center part of a plurality of tongue pieces that protrude to the outer periphery in a substantially disk shape. The plate spring is fixed to the tongue piece in the outer circumferential direction of the piece, and the plate spring is attached to a disc-shaped yoke having a plurality of radial grooves, and the armature of the plate spring is movable within the groove of the disc-shaped yoke. By arranging the armature loosely, the armature stores strain energy against the elasticity of the leaf spring and is attracted to the electromagnetic core by the magnetic flux of the permanent magnet, and the magnetic flux of the permanent magnet is reduced by energizing the electromagnetic coil attached to the electromagnetic core. In a dot print head that performs printing by driving a dot wire together with an armature by the strain energy of the leaf spring, the outermost and innermost edges of the H-shaped slit in the tongue of the leaf spring are removed. The dot print head is characterized by having an effective spring part that is thinner than the other parts, avoiding the edges.
