摘要： A printer head with overlapping nozzles. A plurality of head chips are formed in an array pattern on the printer head wherein a plurality of nozzles are associated with each head chip. Nozzles associated with one head chip and nozzles associated with an adjacent head chip partly overlap to form an overlapped area. When an ink-ejecting mechanism drives across a print object, the nozzles of the one head chip and the nozzles of the adjacent head chip respectively eject inks which are mixed in the overlapped area to reduce dot density differences on the print object.

摘要： The present invention provides an apparatus for discharging liquid in which nozzles (31) allocated to head chips (25) are so arranged as to overlap at parts of adjacent head chips (25), and the distance Ls between nozzles of adjacent head chips of the same color is set to be even number pitches, while the distance Ld between nozzles of head chips of different color is set to be even number pitches. Thus, tiling part can be printed in the hound's tooth manner in driving line heads employing tiling which has overlapped parts formed therein under time division drive. The problem that coloring of superposed colors at overlapped parts becomes different from that at non-overlapped parts can be prevented.

摘要： An ink-jet printer and an apparatus and a method of driving a recording head for an ink-jet printer are provided for faithfully performing various image representations through ink droplet ejection driving signals of different waveforms. Based on a waveform selection signal from a selection controller, a waveform selector selects one of a plurality of drive signals from a drive waveform generator in a time-division manner. The selected signal is supplied to a piezoelectric element of a corresponding nozzle. Control is thereby performed on ink droplet ejection with a drive signal having a temporally varying waveform. The drive signals include a signal having a varying voltage waveform that disables ink droplet ejection in isolation from another waveform. A new composite drive signal waveform is generated by time-divisional selection not only at a point between ejection cycles but also at a point during the ejection cycle.

摘要： An ink-jet printer and a drive method for driving a recording head of an ink-jet printer are provided for controlling a size and a velocity of an ejected ink droplet. The ink-jet printer includes a droplet outlet orifice through which an ink droplet is ejected, an ink chamber communicating with the outlet orifice, an ink feed duct for feeding ink to the ink chamber, and a piezoelectric element for expanding and contracting the ink chamber in response to an applied voltage. A process for ink ejection includes a first step in which a meniscus in the outlet orifice is retracted towards the ink chamber by expanding the ink chamber, a second step in which the meniscus is moved towards the orifice by filling the chamber with ink, and a third step in which an ink droplet is ejected by contracting the ink chamber. The size and the velocity of the ink droplet ejected in the third step are controlled by controlling a position and a velocity of periodic travel of the meniscus at a start point of the third step.

摘要： An ink-jet printer and an apparatus and a method of driving a recording head for an ink-jet printer for suppressing satellite droplets. Two piezoelectric elements are provided for every ink chamber corresponding to each nozzle. Timing of displacement of the piezoelectric elements is adjusted by applying a drive signal for ink droplet ejection to one of the piezoelectric elements and a drive signal for suppressing satellite droplets when a droplet is ejected to the other piezoelectric element. An auxiliary pressure generated by the displacement of the latter piezoelectric element is superimposed on an ejection pressure generated by the displacement of the former piezoelectric element. Trailing of an ink droplet is cut off at an early stage and generation of satellite droplets is suppressed.

摘要： An inkjet print head includes one nozzle sheet (23) and a plurality of head chips (25) including a plurality of heaters. The nozzle sheet (23) is formed of an electroformed metal layer made of nickel or a material comprising nickel, and has discharge nozzle rows for respective colors disposed so that the discharge nozzles are in staggered arrangements and so that each set of discharge nozzles partly overlaps another set of discharge nozzles in a sheet-feed direction. The head chips are positioned at and affixed to a growth surface side of the nozzle sheet (23) in staggered arrangements so that the positions of the discharge nozzles and the positions of the heaters correspond to each other. Accordingly, reduction in printing quality caused by displacement of any of the discharge nozzles is prevented from occurring, and landing positions of discharged ink on a recording sheet are stabilized.
