Title: Ink jet recording head
Inventor: MATSUMOTO HIROZO
IPC: B41J2/20
Filed: 1987-03-13
Abstract: PURPOSE:To prevent the formation of an electric field in an ink cavity at the time of voltage application, eliminate the electrolysis of water soluble ink and generation of air bubbles and prevent the clogging of an ink nozzle attributable to the air bubbles, by depositing a conductive layer to serve as electrostatic shielding to the inner surface of an ink cavity. CONSTITUTION:A switch 9 is selectively turned on under a condition where ink is supplied to an ink supply channel 2 from outside and a voltage is applied to between split electrodes 5a, 6a in the area of an ink cavity 3 corresponding to a designated ink nozzle 4. Subsequently, the volume of the cavity 3 is permitted to shrink and liquid droplets are ejected forward from the nozzle 4. At that time, the internal peripheral surface of the cavity 3 is surrounded with a conductive layer 7. This arrangement results in the generation of no electric field at all in the ink cavity 3 when the voltage is applied. For this reason, no air bubbles generate due to the electrolysis of ink even if a water base ink is used, and at the same time, the clogging of the ink nozzle 4 attributable to the air bubbles is prevented.
