LIQUID SUPPLY APPARATUS

A rotary screen apparatus (100) includes: a hollow cylinder (121) having multiple holes formed therein and configured to come into contact, at its outer peripheral surface, with the surface of a sheet held on an impression cylinder (110); a rotary screen (120) including a squeegee (124) configured to extrude ink (1) delivered to the inner peripheral surface of the hollow cylinder (121) through the holes by coming into contact with the inner peripheral surface of the hollow cylinder (121); and a restricting plate (127), disposed on the downstream side of the squeegee (124) in the moving direction thereof in relative movement of the hollow cylinder (121) and the squeegee (124) performed when the ink (1) is extruded through the holes in the hollow cylinder (121), for restricting movement of the ink (1) such that the ink (1) is kept within a space (121a) present on a downstream side of the portion of the squeegee (124) in contact with the hollow cylinder (121) in the moving direction.
