PROBLEM TO BE SOLVED: To provide a liquid coating device that avoids ejection amounts of liquid from increasing sharply at an initial stage of ejection of the liquid.SOLUTION: The liquid coating device comprises: a first gas supply piping 51 and a second gas supply piping 53 which supply gas from a gas supply source 50; a liquid coating part 10 that is provided near the first gas supply piping 51 and has a trigger 18 for performing liquid coating operation; a liquid supply pump 40 that is provided near the second gas supply piping 53, driven by gas from the second gas supply piping 53 and supplies liquid to the liquid coating part 10; a normal close type valve 60 that is provided on the second gas supply piping 53 closer to the gas supply source 50 than the liquid supply pump 40 and performs opening/closing operation by gas; and a third gas supply piping 55 that is connected to an opening/closing operation gas supply part 61 of the normal close type valve 60 and supplies the opening/closing operation gas supply part 61 with the gas supplied to the first gas supply piping 51 in interlock with triggering motion of the liquid coating part 10.SELECTED DRAWING: Figure 2 |
