Abstract
A recording head for ink mosaic printers has a plurality of channels communicating with an ink supply each of which has an individually controllable electro-mechanical transducer operable to eject ink droplets from respective channels and each channel further having at least two nozzle openings through which the ink is ejected toward a carrier medium for achieving a finer pattern of droplets on the carrier medium for improved resolution and adaptability to different types of texts.
Claims1
A recording head for use in an ink mosaic recording device comprising a plurality of channels in said recording head communicating with an ink supply, said channels terminating at a common face adjacent to a recording medium, an individually operable electro-mechanical transducer associated with each channel for selectively ejecting droplets of ink from said channels, each channel terminating in four nozzle openings disposed at the corner of a rhombus on said face and said nozzle openings being disposed in at least two parallel rows, with a lowest nozzle opening of a rhombus in a first row of nozzle openings and an uppermost nozzle opening of a rhombus in a row parallel thereto being disposed at the same level.
