FLOW CHANNEL MEMBER FOR LIQUID DISCHARGE HEAD, LIQUID DISCHARGE HEAD USING THE SAME, AND RECORDING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a flow channel member for liquid discharge head converting the head to that having few fluctuation in discharge characteristic when the hole position on a plate being a flow channel is displaced, and to provide the liquid discharge head and recording device using the flow channel member.SOLUTION: A flow channel member 4 for liquid discharge head is configured by laminating the plates 4a to 4m and includes a first plate 4c having a first hole 7c, a second plate 4d having a second hole 7d and a third plate 4e having a third hole 7e. The opening 7cb of the lower side of the first hole 7c, and the opening 7ea of the upper side of the third hole 7e have the areas overlapping with each other and those which do not overlap with each other, and the above openings 7cb and 7ea fall into the inside of the second hole 7d.SELECTED DRAWING: Figure 5
