ABSTRACT:
A mechanism which has a first cam plate pivotally mounted on an operating shaft having an operating lever joined thereto and a second cam plate pivotally mounted on an eccentric shaft of a master cylinder and moved with an arm fixed to the operating shaft. The first cam plate is formed with a pump switch cam, a set cam for operating the operating lever stepwise and a paper feed control cam. The second cam plate is formed with a form roller-separating cam and a master cylinder-separating cam. The form roller-separating cam causes press contact between a form roller and the master cylinder when the operating lever is set at the I position. When the operating lever is set at II, the master cylinder-separating cam forces the master cylinder to maintain its contact with a blanket cylinder, and when the operating lever is set at IV, the paper feed control cam allows a suction foot to move down to start paper feed through an auxiliary operating lever.
