Abstract
A stencil printer includes an ink drum having a hollow cylindrical porous support and a pair of flanges supporting opposite ends of the support. Annular elastic members are respectively affixed between the inner periphery of the porous support and the outer circumferences of the flanges. When the ink drum is pressed against a press roller, the elastic members deform and cause an ink roller disposed in the ink drum to be displaced. As a result, the ink roller contacts the inner periphery of the porous support brought into contact with and positioned by the press roller. The ink roller and the inner periphery of the ink drum can therefore contact each other under uniform pressure without the rigidity of the drum being reduced and without any shaking.
