摘要： For printing, the principle of the continuous deflected jet is used: a device discharges a continuous stream of a liquid, which is deflected by an electric field created by a plurality of deflecting electrodes and directed toward a gutter. The printing of drops is performed by fragmenting the continuous jet into a segment formed opposite a shield electrode upstream of the deflecting electrode, so that the segment is not deflected and can be directed toward a substrate.The deflection electrodes are separated by an insulator and a variable potential is applied to each electrode; the potential for the entire set of electrodes cancels out such that the jet is not charged.

摘要： An ink jet apparatus electrifies ink (2) in a nozzle (4), and ejects the ink (2) from an ink ejecting hole (4b) onto a printing medium (8) by a first electric field generated between the nozzle (4) and the printing medium (8). The ink jet apparatus includes an ink catching device which includes an ink catching portion (14) provided at a position adjacent to the nozzle (4) and catches an ejected substance ejected from the nozzle (4). In addition, between the nozzle (4) and the ink catching portion (14), the ink jet apparatus applies a voltage for generating a second electric field which (i) causes the ejected substance, which is formed from the ink (2) or the ink (2) whose viscosity is changed, to be ejected from the nozzle (4) and (ii) causes the ink catching portion to attract the ejected substance. With this, in a configuration which utilizes an electrostatic force to eject fluid, it is possible to promptly remove a clogging of an ejection head at any position, and it is also possible to realize less initial ejection fluctuation and improve the reliability of ejection.
