Ink jet head with an integrated charging control circuit

摘要

In an ink jet head for performing charging and discharging between diaphragms and electrodes to transform the diaphragms to thereby eject ink drops from nozzle holes, a control circuit (60) of this ink jet head is constituted by an integrated circuit which is provided on a nozzle plate (300), a diaphragm substrate (200) or an electrode glass substrate (100) of an ink jet head chip (7).
