Abstract
An ejection device includes: ejection portions that eject liquids; supply portions that supply the liquids to the ejection portions respectively; a common pressure applying mechanism that applies pressure onto the liquids at the supply portions; and a pressure difference generating mechanism that generates a relative pressure difference between the ejection portions for the liquids to be supplied from the supply portions to the ejection portions.
Claims14
An ejection device comprising:
- ejection portions that eject liquids;
- supply portions that supply the liquids to the ejection portions respectively;
- a common first pressure applying mechanism that applies pressure onto the liquids at the supply portions;
- a first pressure difference generating mechanism that generates a relative pressure difference between the ejection portions for the liquids to be supplied from the supply portions to the ejection portions;
- collection portions that collect the liquids from the ejection portions respectively;
- a common second pressure applying mechanism that applies pressure onto the liquids at the collection portions;
- and
- a second pressure difference generating mechanism that generates a relative pressure difference between the ejection portions for the liquids to be collected from the ejection portions into the collection portions.

An ejection device comprising:
- ejection portions that eject liquids;
- supply portions that supply the liquids to the ejection portions respectively;
- a common first pressure generating mechanism that generates reference pressure as a reference for the liquids to be supplied from the supply portions to the ejection portions respectively;
- a first change mechanism that changes the reference pressure generated for the liquid to be supplied from one of the supply portions to one of the ejection portions, to different pressure;
- collection portions that collect the liquids from the ejection portions respectively;
- a common second pressure generating mechanism that generates reference pressure as a reference for the liquids to be collected from the ejection portions into the collection portions;
- and
- a second change mechanism that changes the reference pressure generated for the liquid to be collected from one of the ejection portions into one of the collection portions, to different pressure.
