。[Claims for Utility Model Registration] (1) An ink applicator roller, a doctor blade that can freely move forward and backward with respect to the ink applicator roller, and an eccentric roller that adjusts the pushing amount of the doctor blade with respect to the ink applicator roller according to eccentric rotation. and a control section that controls the amount of rotation of the eccentric roller. (2) The phase of the eccentric roller is selected so that as the pushing amount of the doctor blade increases, the leg of the moment acting around the roller axis becomes shorter. The inking device described in section. (3) The maximum pushing value of the doctor blade by the eccentric roller is set to a value that does not cause permanent deformation to the ink form roller, as described in claim (1) or (2) of the utility model registration claim. inking device.
