Abstract:
An ink-jet print head comprising: a manifold having an ink supply channel opened on its one surface; an actuator formed with a plurality of ejection channels in a plurality of rows, the actuator having first and second end surfaces opposite to each other, the plurality of ejection channels extending between the first and second end surfaces to open at both of the first and second end surfaces, the actuator being connected, at its first end surface, to the manifold so that the ink supply channel is provided on a side of the manifold in correspondence with the plurality of rows of ejection channels and the plurality of ejection channels are in fluid communication with the ink supply channel for receiving ink from the ink supply channel the actuator selectively ejecting ink from the opened ends of the ejection channels at the second end surface; and means for providing an ink flow path on the first end surface of the actuator to ensure that ink flows from the ink supply channel to the ejection channels, where the ejection channels, in each ejection channel row are connected with one another along the direction in which the subject channel row extends, and where the ink supply channel and the ink flow path are integrated together to allow ink to flow in the direction in which the ejection channel rows extend, ensuring supply of ink to each ejection channel in each ejection channel row.
