摘要：
PROBLEM TO BE SOLVED: To realize a control method for a fluid ejection device capable of switching between pulse flow ejection and continuous flow ejection.SOLUTION: A fluid ejection device comprises: a pulsating flow generation section that has a fluid chamber and capacity change means for changing a capacity of the fluid chamber and ejects fluid as pulse flow or continuous flow from a fluid ejection opening portion fluid supply means for supplying the fluid to the pulsating flow generation section at a predetermined pressure and ejection command switch means for selectively switching between pulse flow ejection and continuous flow ejection. A control method for the fluid ejection device selectively switches between the pulse flow ejection that drives the capacity change means, converts the fluid into pulsating flow and ejects the fluid in a pulse manner and the continuous flow ejection that stops the capacity change means, increases a fluid supply pressure from the fluid supply means in comparison with the pulse flow ejection and ejects the fluid as the continuous flow by the ejection command switch means.COPYRIGHT: (C)2014,JPO&INPIT【課題】パルス流噴射と連続流噴射とを切替え可能な流体噴射装置の制御方法を実現する。【解決手段】流体噴射装置の制御方法は、流体室と前記流体室の容積を変更する容積変更手段とを有し、流体噴射開口部から流体をパルス流または連続流として噴射させる脈流発生部と、前記脈流発生部に所定の圧力で流体を供給する流体供給手段と、パルス流噴射と連続流噴射とを選択的に切り替える噴射指令切替え手段と、が備えられる流体噴射装置の制御方法であって、前記容積変更手段を駆動し流体を脈流に変換してパルス状に噴射させるパルス流噴射と、前記容積変更手段を停止し、パルス流噴射の場合よりも前記流体供給手段からの流体供給圧力を高めて流体を連続流として噴射させる連続流噴射と、に前記噴射指令切替え手段により選択的に切替える。【選択図】図5
