摘要： An ink-jet recording apparatus includes a pressure chamber that contains ink, a nozzle communicating with the pressure chamber, which ejects the ink from the pressure chamber, an ink-jet head having an actuator that increases and decreases the capacity of the pressure chamber, and a driving signal generation unit that supplies the actuator with a driving signal to eject an ink drop from the nozzle. When no ink is ejected from the nozzle, the actuator is supplied with a very low pressure driving signal to increase the capacity of the pressure chamber and then return the increased capacity to an original size. The pulse width of the very low pressure driving signal is about twice as long as a pressure propagation time period during which a pressure wave in the ink propagates through the pressure chamber.

摘要： The invention provides a process for producing a dot printer head wherein a plurality of needles having their ends arranged along a straight line have gradually increasing lengths towards opposite outer end ones thereof so that when the needles are being inserted into respective needle holes in a needle guide, they can be positioned one after another each under the guidance of a needle located outwardly adjacent thereto. Thus, even where an arrangement of needles is such that there remain some gaps between adjacent needles, the needles can be guided one after another beginning with the outermost ones thereof and be inserted smoothly into the needle holes.

摘要： A dot printer head in which a radial array of armatures are disposed opposite to a yoke and cores equipped with coils, and the armatures are actuated together with needles by exciting the coils to perform a desired printing operation. In this arrangement, a magnetic flux generated from each core flows to the yoke via the associated armature and then returns to the former core while partially flowing through another magnetic path by way of the adjacent armature to the yoke and returning to the former core, whereby required magnetic paths are obtained without the necessity of increasing the areas of the mutually opposed surfaces of the armature and the yoke. Thus, the radial width of the yoke is reduced as well as the distance from the fulcrum of the armature to the core, so that the distance from the fulcrum of the armature to the fore end thereof can be sufficiently lengthened against the distance from the armature fulcrum to the core. Consequently, a great force of magnetic attraction is producible while the air gap between the armature and the core is maintained to be narrow, and furthermore the equivalent mass of the armature can be reduced to achieve high-speed printing with an economy of the power consumption.
摘要翻译：一种点式打印头，其中电枢的径向阵列与磁轭相对设置并配备有线圈，并且通过激励线圈来使电枢与针一起致动以执行期望的打印操作。在这种布置中，从每个核心产生的磁通量通过相关联的电枢流到磁轭，然后返回到前一个磁芯，同时通过另一个磁路通过相邻的电枢到磁轭并返回到前一个磁芯，由此可以获得所需的磁路，而不需要增加电枢和轭的相互相对的表面的面积。因此，轭的径向宽度以及从电枢的支点到芯的距离减小，使得从电枢的支点到其前端的距离可以相对于距电枢的距离被充分地延长支点到核心。因此，可以在电枢和铁芯之间的空气间隙保持较小的同时产生大的磁吸引力，并且还可以降低电枢的等效质量，从而实现高耗电量的经济性。

摘要： An ink-jet head is formed by partitioning a plurality of ink chambers made from piezoelectric members from each other. Ink chambers which emit ink and dummy ink chambers which do not emit ink are arranged alternately, and ink is supplied to the ink chambers from a common ink chamber. This ink head is used to sequentially perform emission of an ink drop from the ink chambers for a plurality of times, to achieve gradation printing, while the emission speed of the ink drops is gradually increased such that ink drops emitted later are merged with ink drops emitted earlier thereby to form a one-dot liquid drop. In this case, where adjacent ink chambers with a dummy ink chamber inserted therebetween are simultaneously driven, timings of drive pulse voltages q1 and q2 applied to both of the adjacent ink chambers are shifted from each other such that the pressure in one of the adjacent ink chambers is decreased when the pressure in the other of the adjacent ink chamber is increased.

摘要： A sheet passage is formed so as to extend from a sheet feed position via a printing position to a sheet delivery position, delivery rollers driven by a driving unit are disposed between the printing position and the sheet delivery position on the sheet passage, pressure rollers are disposed on one side of the sheet passage so as to be in contact respectively with the delivery rollers disposed on the other side of the sheet passage, a back sheet guide is disposed between the delivery rollers and the sheet delivery position, and a printed sheet delivered by the delivery rollers and guided by the back sheet guide is transferred to a printed sheet storage unit by sheet transfer arms. Thus, the time required to transfer the printed sheet from the delivery rollers to the printed sheet storage unit is extended so that the time between the delivery of the preceding sheet to the printed sheet storage unit and the delivery of the succeeding sheet to the printed sheet storage unit is extended to prevent the smearing of the preceding printed sheet previously stored in the printed sheet storage unit with the ink by the succeeding printed sheet.
