Coating apparatus, dryer, light irradiation device and coating system

Abstract

A coating apparatus 10 for applying a film-forming liquid to a peripheral edge of a board while moving a board and a coating unit 20 relative to each other, wherein the coating unit 20 includes a coating mechanism 21 and an extension mechanism 30, and wherein the coating mechanism 21 has a coating part 22 for applying the film-forming liquid to at least a peripheral edge face of the board, and wherein the extension mechanism 30 has a coating part 22 for applying the film-forming liquid to at least a peripheral edge face of the board. The extension mechanism 30 has an extension part 31 that extends the film-forming liquid applied by the application part 22 to the peripheral edge face and the peripheral upper and lower faces of the board in the form of a thin film, and a force mechanism 34 that forces the extension part 31 toward the peripheral edge face and the peripheral upper and lower faces of the board, and the extension part 31 is configured to be removable without removing the force mechanism 34 from the extension mechanism 30.
