回路。[Scope of claim for utility model registration] An armature with a printing wire fixed to the tip,
A core provided opposite to the armature, a leaf spring to which the armature is joined and supported in a cantilevered manner, and a magnetic flux is generated to resist the elastic force of the leaf spring to move the armature to the core. In the print head drive circuit of an impact printer, which consists of a permanent magnet that attracts the permanent magnet, and a coil that is wound around the core and generates magnetic flux from the core when energized, canceling the magnetic flux of the permanent magnet and releasing the armature, (a ) Piezoelectric elements are arranged so as to make the spring force of the leaf spring variable, and (b) the coil and the piezoelectric element are connected to each other so that the reactance is opposite and impedance matching is performed. Head drive circuit.
