Title: Ink jet printer head
Inventor: MIYAZAWA HISASHI
IPC: B41J2/055
Filed: 1990-09-10
Abstract: PURPOSE:To obtain stable ink discharge properties by guiding an amplitude conversion actuator of a magnetic material using a magnet guide plate consisting of a paramagnetic material. CONSTITUTION:If a pulse is applied to a piezoelectric element 1, the piezoelectric element 1 becomes stretched sharply and an amplitude conversion actuator 4 is guided by a magnet guide plate 5 to come close to a nozzle orifice 6a in a nozzle plate 6. If an ending pulse is applied, the piezoelectric element 1 becomes contracted instead of stretched. Subsequently, the amplitude conversion actuator 4 further approaches the nozzle plate 6 by its inertia, as the upward movement of the actuator 6 is not restricted by the piezoelectric element 1. Then the speed is reduced to 0 when the actuator 4 comes in contact with the nozzle plate 6. Next, the actuator 4 shifts to a restoration process due to a reaction force generated by the weight and impact with the nozzle plate 6 of the actuator 4 and further, a magnetic force portion generated by the magnet guide plate 5 becoming offset from a neutral line. Finally the actuator 4 comes in contact with the upper surface 1a of the piezoelectric element 1 to be initialized.
