Patent ID: 7871141

Claim:
A liquid ejecting apparatus comprising: a liquid ejecting head that includes: a pressure chamber that is in communication with a nozzle opening; and a pressure generating device that is configured to generating pressure fluctuation in liquid present in the pressure chamber, wherein the liquid ejecting head discharges the liquid present in the pressure chamber from the nozzle opening in the form of a liquid droplet by operation of the pressure generating device; and a driving signal generating device that generates a driving signal that includes a discharge pulse for discharging the liquid droplet by driving the pressure generating device during every discharge period, wherein the driving signal generating device sets, into the discharge pulse, an expansion element for expanding the pressure chamber, a discharge element for discharging the liquid droplet by contracting the pressure chamber that is expanded by the expansion element, and a vibration damping element for suppressing residual vibration, which occurs in the pressure chamber after the liquid droplet is discharged, by further contracting the pressure chamber, and the driving signal generating device sets a period of time from a trailing edge of the discharge element to a leading edge of the vibration damping element in a range of ⅓ to ⅔ of a characteristic vibration period Ta of the pressure generating device.
