LIQUID DELIVERING METHOD AND LIQUID DELIVERING APPARATUS

PROBLEM TO BE SOLVED: To realize to drive a liquid delivering head appropriately and universally which can effectively prevent satellite from being generated regardless of various conditions such as physical properties of a liquid delivered and a head structure. SOLUTION: The liquid delivering head is driven based on the change in volume so that a liquid elongated in a pillar shape when a liquid droplet (main droplet) is separated becomes gradually to a thicker shape from the separated part toward a delivering opening, and in a period when the length of the liquid elongated in the pillar shape after the liquid droplet is separated becomes shorter, the liquid is protruded from the delivering opening. It is possible thereby to prevent effectively the liquid pillar from being divided furthermore after the main droplet is separated, and to suppress generation of the satellite regardless of the various conditions such as physical properties of the liquid delivered and the head structure.
