PROBLEM TO BE SOLVED: To provide a cylinder device of a printer which has a simple configuration and can adjust a printing pressure in at least three cylinders with a high accuracy.SOLUTION: A cylinder device of a printer includes: an assembly plate cylinder 22 which is so supported as to approach and be separated from an assembly rubber cylinder 21 and a rubber cylinder 19; an eccentric inner metal 42 which rotatably supports the assembly plate cylinder 22, and so rotates the assembly plate cylinder 22 that the assembly plate cylinder 22 approaches and is separated from the assembly rubber cylinder 21; a hydraulic cylinder 45 for rotating the eccentric inner metal 42; an eccentric outer metal 43 which pivots the eccentric inner metal 42 and so rotates the eccentric inner metal 42 that the assembly plate cylinder 22 approaches and is separated from the rubber cylinder 19; a drive unit 46 for rotating the eccentric outer metal 43; a stopper 49 provided on a frame 44 of this device; and an adjusting bolt 47 which is provided on the eccentric inner metal 42, and contacts the stopper 49 when the assembly plate cylinder 22 makes contact with the assembly rubber cylinder 21. |
