摘要： An on-demand type ink jet print head including a drive assembly formed from a vibrating plate formed of a piezoelectric layer with an electrode layer on one surface and an electrically conductive, physically resilient layer on the opposite surface of the piezoelectric layer. The vibrating plate is secured to a base and has two opposing edges defining a free space therebetween. The vibrating plate is slit into a plurality of strips and these strips are cross-slit in the widthwise direction to form a row of reed pieces secured to each opposing edge of the base in a cantilever configuration and extending into the free space from each edge toward the reed pieces extending from the opposite edge with a space therebetween. The reed pieces are electrically and mechanically independent of each other and have negligible electrical and mechanical interference with each other. Selective application of an electric field to the piezoelectric layer causes the reed pieces to deflect and jet ink from the print head onto a recording medium.

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。
