LIQUID DISPENSING APPARATUS

摘要

A coater for fluid is provided to reduce the time required for measuring the height of the plane where fluid is coated by allowing the height of a nozzle to be changed in real time according to the movement of a roller. A coater(100) for fluid comprises a roller(110) which moves in one direction along a substrate with irregular surface; a drive part which moves the roller in one direction; an elastic member(132) which is installed between the roller and the drive part and is shrunk or expanded according to the change of the height of the roller; and a nozzle(140) which is installed at the one side of the elastic member, whose position is changed according to the change of the position of the roller and which coats fluid on the substrate.
