LIQUID JET STRUCTURE, INK JET TYPE RECORDING HEAD AND PRINTER

摘要

A liquid jet structure equipped with a nozzle (11) for jetting a liquid (6), characterized in that the flow passage (140, 130) inside the nozzle is set in such a fashion that its degree of affinity for the liquid (6) to be jetted varies depending on the flowing direction of the liquid. The straight moving property of the droplets can be improved and the diameter of the droplets can be stabilized by controlling this affinity. This liquid jet structure is suitable for an ink jet recording head.
