キ装置。[Scope of Claim for Utility Model Registration] 1. In an inking device of a rotary printing press that holds ink in an ink reservoir and controls ink deposition by forming the ink into a thin layer, , an ink metering blade arranged in parallel with the ink dispenser roller and having one edge fixed to the ink reservoir and the other edge held so as to be able to come into contact with the circumferential surface of the ink dispenser roller; a hard ink amount setting roller that is arranged parallel to the back of the blade in contact with the blade and is rotatable concentrically; the circumferential surface of the ink amount setting roller has a thin step near the center; In an inking device of a rotary printing press, the length of the step in the axial direction gradually decreases in the rotational direction. 2. By providing an operating lever on the back of the ink amount setting processing roller and adjusting this operating lever according to the scale, the contact between the ink dispenser roller and the ink metering blade can be made at the center. 2. The inking device of a rotary printing press according to the above item 1, which is formed by varying minute gaps from side to side around the center.
