Claims

[Scope of utility model registration request]

In a print head that attracts an armature using a magnetic attraction force, releases the magnetic attraction force, and drives a printing wire by strain energy stored in a leaf spring that supports the armature, ferromagnetic plates are formed into different thicknesses. and a thick part is an armature, a thin part is integrally formed as an armature hinge spring, and a plurality of the print head armatures are connected by an extension part of the spring part to form an integral spring. A wire dot type print head is used.
