Abstract: PROBLEM TO BE SOLVED: To process a piezoelectric actuator to a thin constitution without paying attention to a handling convenience by constituting the piezoelectric actuator simply of a sheet and a first, a second conductor layers. SOLUTION: A sheet 50 of a piezoelectric material, a first conductor layer 51 and a second conductor layer 52 are layered to form a multilayer plate 53. The multilayer plate is attached via an adhesive to one face 41A of a channel plate 41. A resist layer 55 is layered on the conductor layer 52. An exposed part of the conductor layer 52 of the multilayer plate 53 is removed by using sandblasting, etching or the like method with use of the resist layer 55 as a mask. The conductor layer 52 is accordingly formed in the same pattern as each upper electrode layer 47 of a piezoelectric actuator 42. An ink-jet print head 40 is thus manufactured. The piezoelectric actuator can be processed to a thin constitution without taking a handling convenience into consideration and a productivity is improved.

Abstract: PROBLEM TO BE SOLVED: To achieve various expressions accurately by jetting ink droplets by driving signals with different wave forms. SOLUTION: A wave form selecting part 141-1 selects any of a plurality of driving signals 145-1 to 145-N from a driving wave form generating part 142 by time sharing based on a wave form selecting signal 146-1 from a driving wave form selecting control part 143 so as to supply it to a piezoelectric element of the corresponding nozzle. Accordingly, the jetting control of ink droplets can be conducted by wave form driving signals different according to the time. The driving signals 145-1 to 145-N also include a driving signal with a predetermined wave form, which is not a certain voltage wave form but cannot have ink droplets jetted by itself. According to the time sharing selection not only per the jetting cycle but also within the jetting cycle, a new driving signal wave form can be synthesized. The other wave form selecting parts 141-2 to 141-n operate in the same manner.
