摘要： A multi-nozzle ink jet head formed through semiconductor processes. The multi-nozzle head has a head substrate in which are formed a plurality of nozzles and a plurality of pressure chambers, a diaphragm that acts as a common electrode and covers the plurality of pressure chambers, piezoelectric body layers that are provided in correspondence with the pressure chambers on the diaphragm, and individual electrode layers that are provided on the piezoelectric body layers and have individual electrode parts corresponding to the pressure chambers and wiring parts for the individual electrode parts. By interposing a low-dielectric-constant layer or an insulating layer in the region of the wiring parts, or not disposing the common electrode in the region of the wiring parts, the electrical capacitance of the driving parts is reduced, and hence a driving lag is prevented from occurring, and moreover unwanted vibration of the piezoelectric bodies is prevented.

摘要： A multi-nozzle ink jet head having a diaphragm that effectively utilizes the force generated by thin-film piezoelectric elements is disclosed. The head (2) has a head substrate (28) in which are formed a plurality of nozzles (39) and a plurality of pressure chambers (29), a multi-layer diaphragm (23-1, 23-2), piezoelectric elements (27), and individual electrodes (26). By making the thickness of the common electrode layer (23-1) of the multi-layer diaphragm be thin but such that problems do not occur during multi-pin driving, optimization of the rigid layer becomes possible, and hence it is possible to use the force generated by the thin-film piezoelectric elements efficiently in ink ejection.

摘要： In a multi-nozzle ink jet head having a plurality of nozzles, cross talk between adjacent elements is suppressed. The head has the nozzles (12), pressure chambers (15), and bimorph drivers. The bimorph drivers have piezos (19) formed on a diaphragm (18). The diaphragm (18) has linear parts (18-1) that convert the generated force from the piezos (19) into displacement, and non-linear parts (18-2) that are provided between the linear parts (18-1) and diaphragm fixing parts. Due to the non-linear parts (18-2), transmission of strain energy to the fixing parts is suppressed, and hence cross talk is suppressed.
