Abstract
Official abstract text for this publication.
In a liquid ejection control device, an operation unit includes a momentum dial for inputting a momentum instructing value related to momentum of a pulsed liquid jet ejected from a liquid ejection device, and a repetitive frequency dial for inputting a repetitive frequency instructing value related to the number of times ejection of the pulsed liquid occurs per unit time. In addition, a controller includes a voltage magnitude setting section that sets voltage magnitude of the drive voltage waveform such that the momentum becomes the momentum instructing value, based on a rising index value related to rising of the drive voltage waveform and the repetitive frequency instructing value.
First claim
Opening claim text (preview).
1 - 13 . (canceled) 14 . A liquid ejection apparatus comprising: a nozzle configured to eject liquid in a pulsed manner; and a monitor configured to display a momentum of liquid to be ejected from the nozzle. 15 . The liquid ejection apparatus according to claim 14 , wherein the monitor displays a number of times an ejection of liquid is performed per unit time. 16 . The liquid ejection apparatus according to claim 15 , wherein the monitor displays a force calculated on the basis of the momentum and the number of times. 17 . The liquid ejection apparatus according to claim 14 , further comprising: a piezoelectric element configured to eject liquid from the nozzle, wherein the monitor displays a voltage magnitude of a drive voltage waveform applied to the piezoelectric element. 18 . The liquid ejection apparatus according to claim 14 , further comprising: a dial or switch configured to input a first instructing value related to the momentum. 19 . The liquid ejection apparatus according to claim 18 , further comprising: a piezoelectric element configured to eject liquid from the nozzle; and a controller configured to generate a drive voltage waveform applied to the piezoelectric element, wherein the controller sets voltage magnitude of the drive voltage waveform such that the momentum becomes the first instructing value.
