INK JET APPARATUS FOR PARTICULATE-CONTAINING INK

摘要

PROBLEM TO BE SOLVED: To provide an ink jet apparatus for a particulate-containing ink capable of suppressing closure of an ink jet head by a particulate and stably delivering the particulate-containing ink by an ink jet system for a long period of time. SOLUTION: The ink jet apparatus has an ink feed part 1 having a feed tank 1a, a liquid-feed pump 1b and an intermediate tank 1c and feeding the particulate-containing tank to the ink jet head 3; the ink jet head for delivering the particulate-containing ink fed from the ink feed part; an ink liquid feed pipe 1d connected to the ink feed part and the ink jet head and for feeding the particulate-containing ink from the ink feed part to the ink jet head. An ultrasonic vibrator 4 is mounted to the ink liquid-feed pipe. COPYRIGHT: (C)2007,JPO&INPIT
