摘要： An ink jet head includes a substrate provided with heat generating members for generating a bubble in ink on a surface of the substrate, a plurality of discharge ports for discharging the ink, the ports opposed to the surface of the substrate, and a plurality of ink flow passages communicating with the plurality of discharge ports to feed the ink. A plurality of the heat generating members is provided in each of the ink flow passages, and the discharge port is arranged on an extension line extending from a center of a pressure generating area composed of the plurality of heat generating members toward the surface of the substrate in a normal direction. Moreover, a distance dhc between centers of each of two heat generating members arranged most apart from each other among the plurality of heat generating members is set to be larger than a diameter do of an aperture of the discharge port. In the ink jet head, even if the center position of the discharge port and the center position of the pressure generating area are somewhat shifted from each other, main liquid droplets of the ink are discharged from the discharge port without generating no shift in their discharge directions.

摘要： The present invention provides a print head that allows the characteristics of ejected ink to be adjusted for each ejection port in spite of a variation in the distance from an ink supply port to the heating element. In the print head according to the present invention, the area of the heating element decreases with increasing distance from the ink supply port and increases with decreasing distance from the ink supply port. The heating element is shaped like a rectangle that is longer in a direction orthogonal to a direction in which the plurality of ejection ports are arranged than in the direction in which the plurality of ejection ports are arranged. The aspect ratio of the heating element depends on the length of an ink channel through which ink is introduced into the bubbling chamber.

摘要： An ink jet head movable in a main scan direction includes first and second groups of ejection outlet arrays disposed on either side of a common liquid chamber and including plural ejection outlet arrays. In the first group, amounts of liquid ejected from outlets of first and second ejection outlet arrays, which are staggered, differ from each other. In the second group, a common ejection amount ejection outlet array ejects the same amount of liquid as that of one of the first and second ejection outlet arrays and a non-common ejection amount ejection outlet array ejects an amount of the liquid that differs from that of the first ejection outlet array group. The ejection outlets of the common and non-common ejection amount ejection outlet arrays are disposed in a staggered arrangement. The ejection outlets of the second ejection outlet array group are disposed with deviation of ½ of an interval at which the ejection outlets of the first ejection outlet array group are arranged. Different sets of the same cyan and magenta colors in the non-common ejection amount ejection outlet arrays are disposed with deviation of ½ of an interval at which the ejection outlets of the non-common ejection amount ejection outlet arrays of other sets are arranged.
