Patent ID: 7438389

Claim:
An inkjet head comprising: (a) a passage defining unit having a plurality of nozzles and a plurality of pressure chambers held in communication with said nozzles; (b) an actuator unit superposed on said passage defining unit and having a plurality of lands, such that said actuator unit is operable based on a drive signal supplied to each of said plurality of lands, to apply an ejection energy to an ink stored in a corresponding one of said pressure chambers of said passage defining unit; (c) first and second driver circuits each having (c-1) a plurality of control signal terminals and (c-2) a plurality of drive signal terminals, such that a control signal can be input to each of said control signal terminals, and such that the drive signal generated based on the control signal can be output from each of said drive signal terminals; and (d) a flat cable on which said first and second driver circuits are disposed, wherein said flat cable has: (d-1) a plurality of output terminals connected to said lands and located between said first and second driver circuits, said output terminals being disposed on said flat cable and being grouped into first output terminals and second output terminals; (d-2) first drive wires connecting said first output terminals and said drive signal terminals of said first driver circuit; (d-3) first controller wires extending from said control signal terminals of said first driver circuit; (d-4) second drive wires connecting said second output terminals and said drive signal terminals of said second driver circuit; (d-5) second controller wires extending from said control signal terminals of said second driver circuit, and (d-6) connector terminals located on one of opposite sides of said second driver circuit that is remote from said first driver circuit, such that said first and second controller wires extend to said connector terminals from said control signal terminals of said first and second driver circuits, and wherein said output terminals includes at least one of (i) a terminal which is most distant from said first driver circuit among said output terminals and which is one of said second output terminals, and (ii) a terminal which is most distant from said second driver circuit among said output terminals and which is one of said first output terminals.
