    摘要: A time from a start end of a contraction portion of a first middle dot drive pulse of a first drive signal to a start end of the contraction portion of a second middle dot drive pulse of a second drive signal is set to Tc/2 or more and Tc or less in the same unit period. In addition, a time from a start end of a preliminary portion of a first small dot drive pulse to a start end of a preliminary portion of a second small dot drive pulse is set to Tc or more. Thus, while a piezoelectric vibrator corresponding to the other side of adjacent nozzles is driven by the second drive signal, a piezoelectric vibrator corresponding to one side of adjacent nozzles is driven by the first drive signal.

    摘要: A liquid ejecting apparatus includes: a liquid ejecting head which includes nozzles, pressure generating chambers communicating with the nozzles, and pressure generating elements causing a pressure change in a liquid of the pressure generating chambers and which ejects the liquid from the nozzles in response to an operation of the pressure generating elements; and a driving signal generating unit which drives the pressure generating elements to repeatedly generate a driving signal containing an ejection driving pulse used to eject the liquid from the nozzles. The ejection driving pulse has a pulse waveform containing a first pressure generating chamber expansion component which expands the pressure generating chamber to draw a meniscus toward the pressure generating chamber side, a pressure generating chamber contraction component which contracts the pressure generating chamber expanded by the first pressure generating chamber expansion component to push the meniscus toward the liquid ejection side, and a second pressure generating chamber expansion component which expands the pressure generating chamber contracted by the pressure generating chamber contraction component to draw the meniscus toward the pressure generating chamber side again. Each of the pressure generating chamber expansion components has a plurality of different potential change ratios.
