    摘要: A liquid jet head is provided with discharge ports for discharging liquid, liquid flow paths conductively connected with the discharge ports, air bubble generating areas for creating air bubbles in the liquid, and movable members arranged to face the air bubble generating areas, each having a free end in a position relatively near to the discharge port with respect to a fulcrum thereof. This movable member is inclined to position the free end of the movable member to release the air bubble generating area partly to the discharge port so as to enable the tangential line of the free end of the movable member on the side of the air bubble generating area or the extended line thereof to reach directly the discharge port formation area having the discharge port on the liquid flow path side before the creation of air bubble on the air bubble generating area, and with this position as reference, the movable member is displaced following the creation of air bubble on the air bubble generating area. With this arrangement, the liquid discharging efficiency and speed are significantly enhanced as compared with the conventional liquid jet head, and due to more stabilized discharge of droplets from the discharge ports, the quality of recorded images is improved.

    摘要: An apparatus uses a liquid ejection head including a first liquid passage communicating with an ejection port, a second liquid passage separated from the first liquid passage by a separation wall, and a movable member formed as a part of the separation wall. In the second liquid passage, a thermal energy generation device is arranged at a position opposing to the movable member. The movable member has a free end portion and a fulcrum. Recovery of the first and second liquid passages is performed by suction and/or pressurization. Upon recovery by discharging the liquid in respective liquid passage having higher flow resistance, the pressurizing force and/or the suction force for the liquid passage having higher resistance is set to be greater that the pressurizing force and/or the suction force for the other liquid passage having lower flow resistance.

    摘要: A method for preserving a liquid-ejection head is disclosed. The method uses the liquid-ejection head having a first liquid-flowing passage that receives a supply of a first liquid and communicates with an ejection port; a second liquid-flowing passage that receives a supply of a second liquid that differs from the first liquid; a bubble generation area formed on the second liquid-flowing passage for heating the second liquid to generate a bubble in said second liquid; and a movable member positioned between the bubble generation area, having a free end on an ejection port's side of the first liquid-flowing passage and a supporting end on other side of the first liquid-flowing passage, where the free end of the movable member is displaced toward the first liquid-flowing passage by a pressure caused by a generation of the bubble when said second liquid is heated. The method includes a step of performing a replacement of one of the fist liquid and the second liquid with the other at least at a periphery of the ejection port or a periphery of the movable member. Thus the liquid-ejection head is able to perform an excellent recording whether it has not been used for a long time.

    摘要: Disclosed are an ink-jet printing method and apparatus for jetting ink successively from nozzles of an ink-jet head at a prescribed frequency and forming each of a number of pixels by a plurality of dots conforming to the tone of the pixel. Each nozzle of the ink-jet head has a heater A and a heater B. Printing is performed by changing the number of heaters actuated to jet an ink drop, thereby to control the formation of a large or small dot by each nozzle, and by changing the method of driving the heaters A and B in dependence upon the density of the ink used. In regard to the timings at which the large and small dots are formed by each nozzle, the small dot is formed first. As a result, the large and small dots can be made to overlap so that an image having excellent tone reproducibility can be printed.

    摘要: Small dots and large dots are recorded with a sufficient difference between them by such structure that a plurality of heat generating elements are disposed inside of each nozzle. A single pulse is applied to one heat generating element for recording of a small dot, whereas a single pulse and a divided pulse are applied to two heat generating elements for recording of a large dot. When the divided pulse is applied to the heat generating element, a larger amount of the ink is ejected than upon application of the single pulse. Therefore, the sufficient difference can be generated between the sizes of dots by applying the driving pulses as described above.
