Abstract: A liquid jet head includes an actuator portion having a first recessed portion, second recessed portions, and left and right channel rows provided between the first and second recessed portions, respectively, and being offset in a row direction by 1/2 of a channel pitch. Each of the left and right channel rows includes channels each having one end portion opened to the first recessed portion and another end portion opened to one of the second recessed portions. The channels are formed of grooves each sandwiched by two of a series of walls extending from the first recessed portion to one of the second recessed portions. A width of the walls corresponding to one of the left and right channel rows being equal to a width of the grooves corresponding to the other of the left and right channel rows.

Abstract: A liquid jet head includes a flow path member having a supply port through which liquid is supplied and a discharge port through which the liquid is discharged, and a cover plate having a liquid supply chamber that communicates with the supply port and a liquid discharge chamber that communicates with the discharge port. An actuator substrate has a plurality of parallel channels that extend between the liquid supply chamber and the liquid discharge chamber and the channels communicate with respective nozzles formed in a nozzle plate. The flow path member, cover plate, actuator substrate and nozzle plate constitute a laminated structure. A communication path is provided in one or both of the cover plate and flow path member for bypassing the liquid from the liquid supply chamber to the liquid discharge chamber so that air bubbles trapped in the liquid can be effectively discharged to the outside.

Abstract: A method of manufacturing a liquid jet head comprises forming a terminal region on a top surface of an actuator substrate in the vicinity of a rear end thereof, and forming on the top surface a plurality of alternately arrayed ejection grooves and dummy grooves arranged in parallel to each other from a front end toward the terminal region. Shallow grooves are formed in the terminal region, and a conductive film is formed on the top surface, side surface and bottom surface of each of the ejection grooves, and on the side surface and bottom surface of the shallow grooves. The conductive film is removed from the top surface by grinding, and a cover plate is bonded to the actuator substrate so as to expose the terminal region and cover the ejection grooves. A nozzle plate is adhered to a side surface of the actuator substrate at which the ejection grooves are opened.
