摘要： A liquid supply device for supplying liquid to a recording head is disclosed. The device includes a liquid container for holding liquid to be supplied to the recording head, a first connecting portion for connecting the recording head and the liquid container, and a second connecting portion having one end thereof in the liquid container, and the other end being open to the air outside and positioned lower in height than the liquid discharge port of the recording head. The device is capable of adjusting negative pressure against the nozzle of the recording head to prevent ink leakage without depending on the deformation of an ink bag.

摘要： The present invention provides a liquid ejection head for which the peeling of an orifice plate from a substrate seldom occurs, even in a structure such that the walls that define each energy application chamber are narrowed toward a ejection port. The walls that define a first pressure chamber are inclined inward within the first pressure chamber, so that the first pressure chamber is narrowed, toward an ejection port, along a direction perpendicular to the heater formation face on which heaters are arranged. Further, the walls that define each ink flow path are inclined in the ink ejection direction. Furthermore, the angle at which the walls that define the ink flow path are inclined relative to the ink ejection direction is smaller than the angle at which the walls that define the first pressure chamber are inclined inward, within the first pressure chamber.

摘要： To provide an inkjet head which includes high-density nozzle rows and which does not easily cause an ejection failure due to adhesion of ink mist around ejection orifices when a high-density image of a secondary color is printed with a small number of paths. An inkjet head includes at least two or more types of nozzle rows that eject different amounts of ink. When A is the cross section, with respect to an ink supplying direction, of an ink supply path from each ejection orifice to a supply port and L is the length of the ink supply path, the value of A/L differs between the two or more types of nozzle rows. The nozzle row of which the value of A/L is small is disposed outside an area between the nozzle rows that eject a largest amount of ink and that are arranged next to each other.

摘要： While the print head is reduced in size, the adverse effect of air flows produced by ink droplets as they are ejected from a small number of ejection opening arrays is minimized. A small number of first ejection opening arrays eject one of three primary colors—cyan, magenta and yellow—and a large number of second and third ejection opening arrays eject the remaining two primary colors. A fourth ejection opening array is disposed between the first ejection opening array and the second or third ejection opening array.
