Title:
LIQUID EJECTION HEAD AND LIQUID EJECTION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2012/014379
Kind Code:
A1
Abstract:
Provided is a continuous liquid ejection head that collects droplets which are not used for printing (unused droplets) without affecting the flight of droplets which are used for printing (used droplets). An ejection nozzle (101) and a collection nozzle (102) collect an unused droplet by causing a liquid surface to project out from the aperture of the collection nozzle (102) so as to be positioned along the trajectory through which droplets ejected from the ejection nozzle (101) fly, causing the unused droplet to collide and unite with the liquid surface projected from the collection nozzle (102), and causing the liquid surface to retreat.
