ELECTROSTATIC SUCTION TYPE FLUID JETTINT DEVICE

摘要

An electrostatic suction type fluid jetting device, comprising a nozzle (4) formed in a shape corresponding to a meniscus equal to a tailor cone-shaped tip part formed in a conventional electrostatic suction process of ink (2) as a fluid, wherein the diameter of the ink discharge hole (4b) of the nozzle (4) is set to a diameter generally equal to the diameter of the tip part of the meniscus (14) immediately before the jetting of the ink and equal to or lower than the diameter of the droplet of the ink (2) immediately after the jetting, whereby both an increase in resolution and safety can be assured and a highly versatile recording device can be commercialized.
