ABSTRACT:
A stencil printer of the present invention includes an ink drum and a press drum rotatable with a paper or similar recording means wrapped therearound while pressing the paper against the ink drum. A moving mechanism selectively moves the press drum into or out of contact with the ink drum in synchronism with the feed of the paper order to prevent the press drum from contacting the ink drum when the paper is absent therebetween. Even when the moving mechanism angularly moves the press drum, the press drum is free from a change in peripheral speed and can surely catch the leading edge of the paper. Drive transmission to the press drum is implemented by an Oldham coupling or a universal coupling.
