LIQUID DISCHARGE HEAD AND RECORDING DEVICE USING SAME |
摘要 |
<p>[Problem] The objective of the present invention is to provide: a liquid discharge head that can reduce crosstalk; and a recording device that uses same. [Solution] The liquid discharge head (2) is provided with: a duct member (4) having a plurality of discharge holes (8) and a plurality of compression chambers (10); and a piezoelectric actuator substrate (21) that has a plurality of second electrodes (25) and that is laminated to the duct member (4) side. In a plan view, the plurality of compression chambers (10) each include: a main electrode body (25a) that has a diamond shape having two obtuse angles (10b) and two acute angles (10a), is disposed at roughly equivalent intervals over rows and columns that are along the diagonals of the diamond shape, and is disposed in a manner so that a second electrode (25) overlaps the compression chamber (10); and a lead-out electrode (25b) of which one end is connected to the main electrode body (25a) and of which the other end is led out to the outside of the compression chamber (10). The lead-out electrodes (25b) pass through one of the acute angles (10a) of the compression chambers (10) and the aforementioned other end is led out to a region that does not overlap the columns.</p> |
