ELECTROSTATIC ATTRACTION FLUID JET DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an electrostatic attraction fluid jet device capable of putting a versatile recorder to practical use while satisfying both high resolution and safety. SOLUTION: A nozzle 4 has a shape corresponding to a meniscus equal to the forward end part of a Taylar cone being formed during an electrostatic attraction process of ink 2 as a conventional fluid. Diameter of the ejection hole 4b of the nozzle 4 is set substantially equal to the diameter at the forward end part of the meniscus 14 immediately before ink ejection and not larger than the diameter of a liquid drop of ink 2 immediately after ejection.
