Patent ID: 8246148

Claim:
A liquid discharge device, comprising: a liquid discharge head, which includes: a plurality of liquid flow channels including a plurality of nozzles configured to discharge liquid; a plurality of pressure applying units configured to apply discharge pressures to the liquid inside the plurality of liquid flow channels, selectively, so that the liquid is selectively discharged from the plurality of nozzles; and a plurality of input terminals formed on a surface of the liquid discharge head, the plurality of input terminals corresponding to the plurality of pressure applying units, respectively; and a first printed circuit board configured to supply drive signals causing the pressure applying units to operate, respectively, wherein the first printed circuit board is formed with: a connection area where a plurality of first connection terminals to be connected with the plurality of input terminals of the liquid discharge head are formed; a pair of extending portions oppositely extending from the connection area, the pair of extending portions being bent with respect to the connection area to form a C-like cross section so that end portions of the pair of extending portions face each other; a plurality of positioning members configured to position the end portions of the pair of extending portions so that the end portions of the pair of extending portions face each other, the plurality of positioning members being configured to be movable along the surface of the liquid discharge head with maintaining a positional relationship among the plurality of positioning members.
