摘要： In an apparatus for measuring an ejection velocity of a liquid droplet ejected from a nozzle orifice of a head device which is provided with a pressure chamber communicated with the nozzle orifice and an actuator which varies pressure of liquid contained in the pressure chamber, a driver generates a drive signal to drive the actuator to eject a liquid droplet from the nozzle orifice. A photo emitter emits a light beam so as to intersect a space through which the liquid droplet passes. A photo receiver receives the light beam which has been passed through the space. A 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 photo receiver.

摘要： A recording head includes a nozzle orifice, a pressure chamber communicated with the nozzle orifice, and an actuator which varies a volume of the pressure chamber. A drive signal generator generates a drive signal in which a plurality of drive pulses are arranged within a unit recording period. The drive pulses includes at least a first drive pulse composed of an expanding element, which drives the actuator so as to expand the pressure chamber, an expansion holding element, which drives the actuator such that the expanded state of the pressure chamber is held in a first time period roughly equal to a first natural vibration period which is a natural vibration period of ink stored in the pressure chamber, and an ejecting element, which drives the actuator so as to contract the pressure chamber so that the ink in the pressure chamber is ejected from the nozzle orifice.

摘要： The drive signal supplied to the piezoelectric vibrator includes the expansion waveform elements (P1, P2, and P3) for expanding the pressure generating chamber, the contraction waveform element (P5) for contracting the pressure generating chamber expanded by the expansion waveform element and jetting an ink drop from the nozzle opening, and the vibration damping waveform element (P7) changing from the terminal voltage (VL) of the contraction waveform element (P5) to the vibration damping voltage (VM) so as to suppress the residual vibration of the meniscus of the pressure generating chamber after jetting an ink drop. The initial and terminal voltages of the drive signal are equal to each other and equivalent to the standby voltage (VL) set as a voltage of the piezoelectric vibrator at the time of non-supply of the drive signal. The vibration damping voltage (VM) lies between the standby voltage VL and the maximum voltage VH of the drive signal. Accidental jetting of ink drops, at the time of recovery of the vibrator voltage using the voltage recovery device, can surely be prevented.
