Claims (1)

[Scope of Claim for Utility Model Registration] (1) In a printing machine in which an inking unit can be set and released at a predetermined position on a printing press body, an ink forming roller, an ink mixing roller, and an ink mixing roller are connected to the ink forming unit. A roller operating mechanism for pressing the forming roller is provided in the inking unit, and an operating member for operating and deactivating the roller operating mechanism in conjunction with the setting/unsetting operation of the inking unit is provided in the inking unit. A printing machine characterized by being installed on the printing machine main body side. (2) The roller operating mechanism includes an operating lever that is pivotally connected to the inking unit so that it can be raised and lowered, and is connected to the operating lever and moves the ink mixing roller in conjunction with the lowering and raising movements of the operating lever. and a link mechanism for press-contacting and releasing the press-contact with the ink form roller, and the actuating member is disposed at a predetermined position of the printing press body and operates the actuating lever to fall in conjunction with the setting operation of the inking unit. The printing machine according to claim (1) of the utility model registration, which is a spring.
