Abstract
A stencil printer capable of conveying a paper by clamping the leading edge portion of the paper and printing an image on the paper is disclosed. Even when an envelope or similar relatively thick paper is used, the printer protects a master wrapped around an ink drum from ripping which would bring about various troubles including the contamination of printings due to ink.
