摘要： In an apparatus for measuring a natural period of liquid in a pressure chamber formed in a head device which is provided with a nozzle orifice communicated with the pressure chamber and an actuator which varies pressure of the liquid contained in the pressure chamber, a driver generates a plurality of drive signals, each of which drives the actuator to eject a liquid droplet from the nozzle orifice under a condition different from the conditions established by the other drive signals. A light emitter emits a light beam so as to intersect a space through which the liquid droplet passes. A light receiver receives the light beam which has been passed through the space. A first calculator calculates an ejection velocity of the liquid droplet based on a timing at which the actuator is driven and a change in a photo-receiving state of the light receiver, with regard to every drive signal. A second calculator calculates a natural period of the liquid based on a change in the ejection velocity which is obtained from the plural drive signals.

摘要： A liquid ejecting apparatus includes a liquid ejecting head and a driving signal generating device. The liquid ejecting head includes a pressure chamber and a pressure generating device. The pressure chamber is in communication with a nozzle opening. The pressure generating device is capable of generating pressure fluctuation in liquid present in the pressure chamber. 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. The driving signal generating device generates a driving signal that includes a discharge pulse for discharging the liquid droplet by driving the pressure generating device during every discharge period. 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. 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.
