[Abstract] An ink fountain device for a printing machine includes an ink fountain roller, a bottom plate, an ink fountain, and a scraper. The ink fountain roller is rotatably supported and the bottom plate is arranged at a position where the distal end portion is close to the ink fountain roller. The ink fountain has a pair of ink dams. The ink dams are arranged in a direction substantially perpendicular to the bottom plate and are opposed to each other in the axial direction of the ink fountain roller. Each of the ink dams includes an elastic member and first and second pushers. The elastic member abuts against the outer surface of the ink fountain roller and the bottom plate. The first and second urging members urge the elastic member toward the outer surface of the ink fountain roller and the bottom plate. The scraper is arranged further downstream of the relative position of the ink fountain roller against the downstream roller in the rotation direction of the ink fountain roller and serves to return the ink attached to the ink fountain roller into the ink fountain.
