摘要： In accordance with the invention, in order to increase the volume of an ink cartridge containing color inks, to prevent the ink cartridge from being improperly mounted on a print head, to ensure that required rigidity of an ink cartridge, and to ensure the viscosities of different inks remain uniform, in an ink cartridge body, a plurality of ink chambers are arranged in at least two linear arrays, and ink supplying ports associated with the ink chambers are also arranged in two linear arrays, whereby the size of the ink cartridge can be reduced, and easy loading of the ink cartridge can be insured. Additionally, the ink supply ports may be arranged in a zig-zag, offset manner to allow for a further reduction in the size of the ink chambers and ink cartridge. The open outer ends of the ink supply ports are formed substantially flush with the bottom walls of the ink chambers. Therefore, the volumes of each of the ink chambers is increased. Further, at least one or the like is provided on the outside of the ink cartridge, to insure the strength and rigidity of the ink cartridge. Circuitous grooves are formed in the surface of a cover member so that the grooves communicating with ink chambers having a smaller volumes are longer than grooves communicating with ink chambers having larger volumes, thus insuring uniform viscosities of all of the inks.
摘要翻译：根据本发明，为了增加含有彩色墨水的墨盒的体积，为了防止墨盒被错误地安装在打印头上，以确保墨盒所需的刚性，并且确保墨盒的粘度不同的油墨保持均匀，在墨盒主体中，多个墨室布置在至少两个线性阵列中，并且与墨室相关联的供墨口也布置成两个线性阵列，由此墨盒的尺寸可以减少，并且可以保证墨盒的容易装载。另外，供墨口可以以锯齿形的偏移方式布置，以允许进一步减小墨室和墨盒的尺寸。供墨口的敞开的外端形成为与油墨室的底壁基本齐平。因此，每个墨室的体积增加。此外，在墨盒的外侧设置至少一个等，以确保墨盒的强度和刚性。在盖构件的表面中形成有凹槽，使得与具有较小体积的墨室连通的凹槽比与具有较大体积的墨室连通的凹槽更长，从而确保所有油墨均匀的粘度。

摘要： Reinforcing ridges are formed so as to project from corner portions of peripheral walls, and an opening end edge is made thick-walled, so that an ink cartridge having a sufficient rigidity can be molded using vapor impermeable soft synthetic resins. In addition, shape keeping ribs are formed so as to project from the outer sides of longitudinal ribs that are formed on an inner surface of a cover body, so that deformation of the cartridge can be suppressed during vibration welding. Further, an engaging recess arranged in a lower surface of an ink cartridge is adapted to receive a support rod of an ink cartridge loading mechanism. A carriage cover body of the loading mechanism is closed as a lifter is guided with a guide groove which is parallel to the axial center of an ink supply needle so that the ink cartridge is allowed to descend correctly toward a recording head, so that the ink cartridge can be loaded correctly without breaking the ink supply needle.
摘要翻译：形成隆起凸起以从周壁的角部突出，并且开口端缘被制成厚壁，从而可以使用不透气的软合成树脂来模制具有足够刚性的墨盒。此外，形状保持肋形成为从形成在盖体的内表面上的纵向肋的外侧突出，使得在振动焊接期间可以抑制盒的变形。此外，布置在墨盒的下表面中的接合凹槽适于容纳墨盒装载机构的支撑杆。装载机构的托架盖主体被关闭，因为升降机被引导与导向槽平行，所述引导槽平行于供墨针的轴心，使得墨盒被允许正确地向记录头下降，使得墨水墨盒可以正确装入，不会损坏墨水供应针。

摘要： An ink cartridge including: an ink chamber for retaining liquid ink; a foam chamber maintained in fluid communication with the ink chamber through a communication hole. An ink supply port for supplying ink from a porous body accommodated in the foam chamber to a recording head is provided. The portion of the foam body confronting the ink supply port is compressed by the ink supply port. The ratio between the amount of ink initially charged in the ink chamber and that of ink absorbed in the porous body is in the range from 1:1 to 1:3. When a cartridge uses more than one color of ink for printing in color, a plurality of foam and ink cartridges are used. The cartridge is filled under reduced pressure while the interior of the cartridge is further evacuated before filling with ink.
