Patent ID: 7234790

Claim:
An ink jet recording apparatus comprising: a head main body having a nozzle array in which a plurality of nozzles for discharging ink onto a recording medium are arranged; a plurality of actuators provided respectively for each of said nozzles, for discharging ink from said nozzles; and a plurality of drive circuits for outputting to said actuators a driving signal based on print data to cause ink to be discharged from said nozzles, wherein said drive circuits comprise a plurality of individual amp circuits connected individually to each of said actuators in order to switch said actuators between either one of a conductive state and a non-conductive state in accordance with said print data, whereby in said conductive state, said driving signal is outputted to said corresponding actuator via a unique individual resistance of said drive circuit, said plurality of nozzles is distributed among a greater number of groups than the number of said drive circuits, and from among adjacent groups, the actuators corresponding to the nozzles belonging to one of said adjacent groups connect to said individual amp circuits belonging to one of said drive circuits, and the actuators corresponding to the nozzles belonging to the other of said adjacent groups connect to said individual amp circuits belonging to another of said drive circuits.
