Patent ID: 7578580

Claim:
An inkjet head for ejecting ink droplets in an inkjet manner, comprising: a nozzle unit having a plurality of metal thin plates and a piezoelectric device, adapted to eject the ink droplets; a printed circuit board supplying to the piezoelectric device a drive signal for causing the nozzle unit to eject the ink droplets; a support supporting the nozzle unit and the printed circuit board in opposing relationship to each other; an earth contact disposed on the nozzle unit; a ground contact disposed on the printed circuit board, held at a reference potential; an electrically conductive elastic member disposed between the earth contact and the ground contact, such that a first portion of the elastic member electrically contacts the earth contact, while a second portion of the elastic member electrically contacts the ground contact, to thereby provide electrical continuity between the earth contact of the nozzle unit and the around contact of the printed circuit board, both of which are electrically held at the reference potential; and a movement limiter limiting movement of the elastic member, to thereby prevent the elastic member from being disengaged from the earth and ground contacts.
