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： An inkjet printing press is provided which can hold sheets extremely stably. In an inkjet printing press, an inkjet head 3 is provided at the outer periphery of a printing drum 1 rotated in one direction. The printing drum 1 is provided with holding claws 15 which are opened and closed to hold the leading end of the sheet S, and clamps 21 which can be opened and closed for clamping the trailing end of the sheet S. When the clamps 21 are moved from their open positions to their closed positions, the clamps 21 are moved backward with respect to the rotating direction of the printing drum 1 to impart a tensile force to the trailing end of the sheet S and tighten the sheet so that the trailing end of the sheet is held by a clamp 21 with the sheet in its tight state. Also, the clamp 21 is brought into contact with the periphery of the printing drum 1 by an attracting device to assure the holding of the sheet.

摘要： A printing apparatus includes transporting belt transporting a printing sheet in a flat surface region opposing to respective ejection openings of printing heads, suction force generating means for generating an electrostatic suction force on a transporting surface of the belt and control means for controlling to generate the suction force only in a region opposing to the head. The control means applies positive and negative high potential to the suction force generating means with reference to a potential of the head.
