Abstract:
1. An applicator device comprising: a reservoir tank being configured to trap embrocation; a stage being configured to hold a substrate to which embrocation is applied; a ferrule having a slit-shaped opening section and being installed above the stage; a fluid transfer pump being configured to guide the embrocation within the reservoir tank to the ferrule by carrying out suction and discharge operations alternately, the fluid transfer pump having a first opening and closing valve disposed between the suction opening of the fluid transfer pump and the reservoir tank and being in an opened condition when the suction operation is carried out and being in a closed condition when the discharge operation is carried out; a second opening and closing valve disposed between the discharge opening of the fluid transfer pump and the ferrule and being in an opened condition when the discharge operation is carried out and being in a closed condition when the suction operation is carried out; a driving device being configured to move relatively the ferrule and/or substrate to one another under a condition where the slit-shaped opening section and the substrate are adjacent to one another; a vacuum pump being connected to a chamber of the cylinder, the chamber being arranged not to contact fluid; and a positive pressure imparting device being configured to impart a predetermined positive pressure within the reservoir tank.
