<P>PROBLEM TO BE SOLVED: To achieve a liquid ejection method where an excision force and an excision speed can be adjusted independently. <P>SOLUTION: The liquid ejection method related to a liquid ejection apparatus 1 includes: a pulse generation part 20 for ejecting a liquid so that the liquid is made to be pulsed from a liquid ejection inlet 96 by changing capacity in a pressure chamber 80 using a piezoelectric element 30 and a diaphragm 40; and a pump 10 for supplying the liquid into the pulse generation part 20. The method changes an amount of a liquid supplied from the pump 10 and a frequency (equivalent to a drive frequency of the piezoelectric element 30) of capacity change of the pressure chamber 80 in a relative relation. A capacity change amount (excluded volume) of the pressure chamber 80 changes the excision force, and product of the excluded volume and the drive frequency change the excision speed. Thus, the excision force can be adjusted independent from the excision speed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
