PROBLEM TO BE SOLVED: To improve usability by allowing intensity of a pulse liquid jet to be set according to the user intension.SOLUTION: In a liquid injection control device 70-1, an operation unit 71 includes an adjustment lever 713 for inputting an indication value of a momentum or kinetic energy of the pulse liquid jet injected by a liquid injection device. A control unit 75 includes a frequency setting unit 752 for setting a build-up frequency of a driving voltage waveform to be applied to a piezo electric element 45 so that the momentum or the kinetic energy becomes the corresponding indication value, and an amplitude setting unit 753 for setting the amplitude of the driving voltage waveform.SELECTED DRAWING: Figure 11 【課題】パルス液体ジェットの強さを、ユーザーの意図に沿った設定とすることを可能とし、使い勝手を向上させること。【解決手段】液体噴射制御装置７０−１において、操作部７１は、液体噴射装置から噴射されるパルス液体ジェットに係る運動量又は運動エネルギーの指示値を入力するための調整レバー７１３を含む。また、制御部７５は、運動量又は運動エネルギーがそれぞれの指示値となるように、圧電素子４５に印加する駆動電圧波形の立ち上がり周波数を設定する周波数設定部７５２と、駆動電圧波形の振幅を設定する振幅設定部７５３とを備える。【選択図】図１１
