Title:
LIQUID-DISCHARGING HEAD AND RECORDING DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2013/145259
Kind Code:
A1
Abstract:
[Problem] The purpose of the invention is to provide a liquid-discharging head with a low discharge variability and for which the reliability of the wiring board can be increased, and a recording device using same. [Solution] A liquid-discharging head (2) provided with: a channel member (4), which has pressurizing chambers (10) disposed at roughly equal intervals in both the rows and the columns and a common channel (5); and a piezoelectric actuator circuit board (21), which has second electrodes (individual electrodes) (25). The common channel (5) extends in the column direction and is connected to pressurizing chambers (10), one column each of which are lined up on either side thereof. The second electrodes (25) comprise: a main electrode body (25a); a first extracting electrode (25b-1) extracted from the main electrode body (25a) in a first region (10-1) that overlaps the common channel (5); and a second extracting electrode (25b-2) extracted from the main electrode body (25a) in a second non-overlapping region (10-2). One or the other of the two kinds of extracting electrodes is electrically connected to the wiring board (92) and the two kinds are alternately connected in the column direction.
