Patent attributes
A plate handling apparatus includes a loader, first and second air cylinders, and first and second detection units. The loader is supported to be movable substantially parallel to a paper convey direction and swingable in directions to come close to and be spaced apart from an outer surface of a plate cylinder to perform plate removal/supply. The first air cylinder moves the loader among a first position close to the plate cylinder, a second position spaced apart from the first position in the paper convey direction, and a third position which is between the first position and the second position. The second air cylinder swings the loader among a first swing state where the loader is substantially perpendicular to the paper convey direction, a second swing state where the loader is inclined such that its distal end faces the plate cylinder, and a third swing state which is between the first swing state and the second swing state. The first detection unit detects a position of the loader in the paper convey direction. The second detection unit detects a swing state of the loader.
