Abstract: An inkjet recording device includes a nozzle module, a switching unit, a waveform generating unit, an image recognizing unit and a pulse width modulating unit. The image recognizing unit determines an ejection condition of the ink droplet ejected from the nozzle while referring to ejection data indicating a type of each pixel to be recorded, and generates switch pulse width data that includes the ejection data and the ejection condition. The pulse width modulating unit generates the switch pulse based on the switch pulse width data. The switching unit opens and closes in response to a switch pulse. An opening duration of the switch unit is variable depending on the switch pulse.

Abstract: In a droplet ejection device, a latch circuit acquires discharge data in which a resolution is set up for each resolution section in a transport direction of a recording medium, and sets data elements in each resolution section for respective ones of a plurality of nozzles. An output enable signal generating unit generates an output enable signal periodically at intervals of a different distance. A drive waveform applying unit applies a drive waveform to a common electrode line of piezoelectric elements of the nozzles in synchronization with the output enable signal, the drive waveform having a time to discharge each piezoelectric element gradually. A switching circuit turns on or off a switch based on a logical AND of the output enable signal and the discharge data and grounds an individual electrode of each piezoelectric element.

Abstract: A charge/deflecting electrode is provided on an orifice surface of an inkjet head near nozzle orifices formed in the orifice surface. A suction tube is pressed against the orifice surface and the electrode to retain a space therebetween. When a negative pressure is generated in a suction hole of the suction tube, ink and foreign matter are sucked from the nozzle orifices. The space is asymmetric on left and right sides so the negative pressure develops a whirlpool-shaped flow including a mixture of air and ink near the suction hole.

Abstract: A back electrode 30 is provided at a rear surface side of a recording sheet 60. An orifice electrode 11 is attached to an orifice plate 15 of a head module 10. The orifice electrode 11, the orifice plate 15, and ink filling in a nozzle element 2 are electrically connected to the ground. The back electrode 30 has the potential corresponding to that of a charging/deflecting signal. With this configuration, the orifice electrode 11, a pressure chamber 13, and the back electrode 30 together generates an inclined electric field 85 at a position a close to a center trajectory 90. A charged ink droplet is deflected greatly by the inclined electric field 85, at an early stage of the ink flight, and even greater deflection can be achieved as the flight proceeds.
