Title:
LIQUID DISCHARGE HEAD AND RECORDING DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/097255
Kind Code:
A1
Abstract:
This liquid discharge head comprises a plurality of discharge holes 8, a plurality of pressure parts 30, a plurality of drive circuits (D1-Dn), a switch circuit SW, a first control circuit 101A, and a second control circuit 101B, the liquid discharge head having multiple types of drive signals including a first signal S1 for a pixel of a first size and a second signal S2 for a pixel of a second size. The first control circuit 101A controls the drive circuits so that drive signals of different types are output from different drive circuits. The second control circuit 101B controls the switch circuit SW so that the plurality of pressure parts 30 are connected to the drive circuit outputting the first signal S1 when discharging a droplet that forms a pixel of the first size and are connected to the drive circuit outputting the second signal S2 when discharging a droplet that forms a pixel of the second size. The first control circuit 101A controls the drive circuits so that the drive circuit in charge of outputting the first signal S1 is changed among the plurality of drive circuits.
