To provide a liquid discharge device that can reduce a risk that accuracy in detecting residual vibrations may be deteriorated due to noise occurring in generating a driving signal.SOLUTION: A liquid discharge device comprises: a first discharge part that has a first piezoelectric element and discharges liquid when the first piezoelectric element is driven by a driving signal; a driving signal generating part that generates the driving signal; a first selecting part that performs selection-operation of selecting whether respective voltages of a plurality of driving waveforms included in the driving signal should be applied to the first piezoelectric element or not, on the basis of a print data signal; a residual vibration detecting part that detects residual vibrations of the first discharging part after the voltage of the first driving waveform of the plurality of driving waveforms is applied to the first piezoelectric element; and a control part that generates the print data signal. The control part stops the driving signal generating part, when making the residual vibration detecting part detect the residual vibrations.SELECTED DRAWING: Figure 3 【課題】駆動信号の生成において発生するノイズによって残留振動の検出精度が低下するおそれを低減することが可能な液体吐出装置を提供すること。【解決手段】第１の圧電素子を有し、駆動信号によって前記第１の圧電素子が駆動されることにより液体を吐出する第１の吐出部と、前記駆動信号を生成する駆動信号生成部と、印刷データ信号に基づいて、前記駆動信号に含まれる複数の駆動波形の各々の電圧を前記第１の圧電素子に印加するか否かを選択する選択動作を行う第１の選択部と、前記複数の駆動波形のうちの第１の駆動波形の電圧の前記第１の圧電素子への印加後の前記第１の吐出部の残留振動を検出する残留振動検出部と、前記印刷データ信号を生成する制御部と、を備え、前記制御部は、前記残留振動検出部に前記残留振動を検出させるときは、前記駆動信号生成部を停止させる、液体吐出装置。【選択図】図３
