    摘要： Two arrays of ejection openings which eject relatively large amounts of ink are provided for each of different color inks and are disposed at symmetrical positions in the order of colors in a direction corresponding to a record scan. In addition, a single array of ejection openings which eject relatively small amounts of ink is disposed for at least one color ink. Since the symmetrical disposition in the color order of the ejection opening arrays which eject large amounts of ink prevents color unevenness from appearing even when the bidirectional recording is performed. Since the single array is formed of the ejection openings which eject small amount of ink, and which is used for highly precise recording, it is possible to avoid image deterioration due to the shift of dot formed positions, even when the recording head is mounted in an inclined manner attributable to the variation in manufacturing.

    摘要翻译： 针对每种不同颜色的墨水提供两个排出相对大量墨水的排出口阵列，并且在与记录扫描相对应的方向上以颜色的顺序设置在对称位置。 此外，为至少一种彩色墨水设置排出相对少量墨水的单个喷射口阵列。 由于排出大量油墨的排出口阵列的颜色顺序的对称布置即使在执行双向记录时也防止颜色不均匀。 由于单个阵列由喷射少量墨水的喷射口形成，并且用于高精度记录，所以即使当记录头安装在其中时也可以避免由于点形成位置的移动而引起的图像劣化 一种倾向于制造变化的原因。

    摘要： The present invention discloses an elastic transformable body for adjusting vapor pressure, a vapor pressure adjustment chamber using the same, an ink-jet recording head having a vapor pressure adjustment device and an ink-jet recording device having the recording head, and more particularly to a vapor pressure adjustment device for adjusting negative pressure generated in a liquid chamber in an ink-jet recording head when discharging ink. The pressure adjustment chamber has at least one elastic transformation body having a changeable volume according to vapor pressure to adjust the vapor pressure in a container communicated thereto and a support for supporting the elastic transformation body to the container. In the pressure adjustment chamber, the elastic transformation body includes an approximately circular opening and two surfaces approximately flat before transformation at an outer circumference, in which the two surfaces have a shape extended through a curved portion at a front end opposite to the opening.

    摘要： In a liquid ejecting apparatus in which ink is supplied from an ink tank to a print cartridge detachably mounted on a carriage through a tube, connection between an ink needle at a tube side and an interconnecting member at a cartridge side can sealingly be effected positively, and ink supplying and connecting means can be made compact. A closing film having a small hole and a central slit is provided at a tip end of an interconnecting member made of soft material and fitted into an ink flow-in projection portion of the print cartridge into which an ink needle is inserted. Further, a notched needle tip end avoiding configuration is provided at a lower part of a tip end of the projection portion so that abutment between the projection portion and the ink needle can be avoided when the print cartridge is mounted and dismounted, thereby reducing a shifting amount of a needle holding member.

    摘要： A charging circuit detects a battery voltage Vp and a charging voltage of a main condenser. When a charge of the condenser is instructed, if the battery voltage is smaller than prescribed value Vpo, the charge is performed in a single control mode. And then, when the charging voltage of the main condenser is larger than a prescribed value Vco, the mode is changed to a push-pull control mode from the single control mode. When the charge of the condenser is instructed, if the battery voltage is larger than prescribed value Vpo, the charge is performed in a push-poll control mode independent of the charging voltage.
