Claims (1)

[Scope of Claim for Utility Model Registration] (1) A plate cylinder that is held in the printing press body and can be freely attached to and taken off from the blanket cylinder; an inking unit rotatably supported on a printing press body; a drive mechanism that drives the inking unit to and from the plate cylinder; and a drive mechanism that drives the inking unit to and from the plate cylinder; An offset printing machine comprising an inkling pressure regulating member that maintains the plate cylinder in a predetermined inkling state. (2) The inking pressure regulating member includes a shaft having one end pivotally connected to the rotating shaft of the plate cylinder and having a holding portion provided at the other end to hold the roller shaft of the ink forming roller driven to ink the cylinder. An offset printing machine according to claim (1) of the utility model registration claim, which is a distance regulating member.
