PROBLEM TO BE SOLVED: To allow intensity of a pulse liquid jet to be set in accordance with intention of a user and to improve user-friendliness.SOLUTION: In a liquid injection control device 1, an operation section 71 includes an adjustment lever 713 for variably operating a rising frequency, voltage amplitude or the like of a driving voltage waveform applied to a piezoelectric element 45. Further, in a control section 75, a rising frequency setting section 752 sets the rising frequency in response to operation input to the rising frequency adjustment lever 713 such that a variation per unit operation quantity of the rising frequency adjustment lever 713 in a state of the voltage amplitude of the driving voltage waveform being set to be a predetermined value becomes constant, the variation being related to momentum associated with a pulse liquid jet injected from a liquid injection device.SELECTED DRAWING: Figure 11 |
