摘要： A method of driving an ink jet recording head comprising the steps of: retreating a vibrating plate to a predetermined position from a nozzle opening at such a speed as to allow a meniscus at the nozzle opening to be jetted from the nozzle opening while applying a drive voltage to a piezoelectric vibrating element; holding the vibrating plate at the position; and advancing the vibrating plate toward the nozzle opening when the meniscus has returned to a position 1/3 or more of the farthest retreat position thereof. As a result, a pressure chamber contracted to thereby apply pressure to ink when inertial stream of the ink become stable and heads toward the nozzle opening, producing an ink droplet to be jetted at a predetermined speed irrespective of the position of the meniscus.

摘要： An ink jet type recording head driving circuit comprises: a capacitor which is connected through a first switching transistor and a charging time constant adjusting resistor to a power source, and grounded through a second switching transistor and a discharging time constant adjusting resistor; and a current buffer through which the terminal voltage of the capacitor is applied to a pressure generating member scanning switch circuit. In the circuit, a first pulse for contracting a pressure generating member forming the recording head is applied to the first switching transistor, and a second pulse for expanding the pressure generating member is applied to the second switching transistor, so that the pressure generating member is contracted at a rate set by the capacitor and the charging time constant adjusting resistor, to supply ink into the pressure chamber of the recording head, and then it is expanded at a rate set by the capacitor and the discharging time constant adjusting resistor.
