摘要： An ink cartridge for a printing apparatus providing ink to a print head through a tapered ink supply needle and removably attached to the print head. The ink cartridge includes an ink chamber for containing ink, an ink supply port, a packing member and a valve device. The ink supply port supplies ink from the ink chamber to the print head of the printing apparatus, the ink supply port including an external opening. The packing member is provided in the ink supply port and forms an ink channel for allowing a flow of ink. The packing member seals the ink supply needle of the printing apparatus by fitting therewith. The valve device is contained in the ink supply port and elastically abuts against the packing member. The valve device selectively opens and closes the ink channel in conjunction with the ink supply needle.

摘要： An ink jet recording apparatus achieves increased print speed without reformation of the recording head and without printing quality impairment. The ink jet recording apparatus has a print mode judging means 35 for judging a print mode from an externally applied command, an image developer 32 for developing a single pixel in print data into a plurality of pieces of bit map data and outputting the developed plurality of pieces of bit map data to an image buffer 33, an image reader 34 for thinning the bit map data developed in the image buffer 33 so that at least a single dot is included per pixel and for outputting the thinned data to a recording head 6 when a high speed printing mode has been specified, and a carriage controller 37 for increasing the speed of the carriage to correspond to the thinning operation. Since the dot data includes at least a single dot per pixel, there is no significant impairment of printing quality, and print speed can be increased in proportion to the number of dots reduced.

摘要： A drop-on-demand ink-jet printing head provided with an array of a plurality of piezoelectric elements arranged at regular intervals and fixed at their one ends to a base, the other ends of the respective piezoelectric elements being free ends which are disposed in opposition to nozzle respective apertures, the piezoelectric elements being formed by cutting, at predetermined width, a piezoelectric plate obtained by firing a lamination of paste-like piezoelectric material conductive material stacked alternately in layers. Since each piezoelectric element is composed of a thin piezoelectric plate interposed between electrodes, if a voltage of only about 30 V, which is sufficient to drive the thin piezoelectric plate, is applied across the electrodes, it is possible to largely flex the whole of the piezoelectric element. By this transformation, ink between the top end of the piezoelectric element and the nozzle aperture is discharged to the outside as an ink drop. Because the driving voltage required for forming an ink drop is as low as possible, it is possible to simplify a driving circuit, and because of cutting a piezoelectric plate, it is possible to form small-sized piezoelectric elements with the same accuracy as in a process of producing a semiconductor.

摘要： A recess is formed in a surface confronting an actuator unit of an ink supply inlet forming substrate. When a flow path unit and the actuator unit are bonded together using a fusible film, thermally expanded air is released into the recess to thereby reduce pressure. Further, by arranging the recess at a position confronting a pressure generating chamber, an air layer formed by the recess is allowed to function as a vibration shielding member.
