PROBLEM TO BE SOLVED: To provide a liquid discharge device which can reduce or avoid problems caused by extension of transfer wiring for a driving signal while inhibiting enlargement of a carriage in a large format printer.SOLUTION: A large format printer has: a carriage 24 equipped with a print head; a control circuit board 10 which generates a driving signal generation control signal for controlling generation of a driving signal; a driving circuit board 30 which generates the driving signal on the basis of the driving signal generation control signal; a first cable 19 which transfers the driving signal generation control signal from the control circuit board 10 to the driving circuit board 30; and a second cable 19 which transfers the driving signal from the driving circuit board 30 to the print head. A shortest distance between the control circuit board 10 and the moving carriage 24 is longer than a shortest distance between the driving circuit board 30 and the moving carriage 24. The driving circuit board 30 is provided at a position higher than the control circuit board 10 in a direction of gravity.SELECTED DRAWING: Figure 16 【課題】ラージフォーマットプリンターにおいて、キャリッジが大型となることを抑制しつつ、駆動信号の転送配線が長くなることに起因する問題を、低減及び回避することが可能な液体吐出装置を提供する。【解決手段】プリントヘッドを搭載したキャリッジ２４と、駆動信号の生成を制御する駆動信号生成制御信号を生成する制御回路基板１０と、駆動信号生成制御信号に基づいて駆動信号を生成する駆動回路基板３０と、制御回路基板１０から駆動回路基板３０に駆動信号生成制御信号を転送する第１ケーブル１９と、駆動回路基板３０からプリントヘッドに駆動信号を転送する第２ケーブル１９とを備え、制御回路基板１０と移動するキャリッジ２４との間の最短距離は、駆動回路基板３０と移動するキャリッジ２４との間の最短距離よりも長く、駆動回路基板３０を重力の方向において制御回路基板１０よりも高い位置に設けた。【選択図】図１６
