Title: Stencil printer

Abstract: A stencil printer operable with a master wrapped around a print drumincludes a rotatable print drum. An ink roller is rotatable in the samedirection as the print drum for feeding ink to the inner periphery of thedrum. An ink replenishing roller is rotatable in the same direction as theprint drum and ink roller and movable between a first position where it isspaced from the inner periphery of the drum and ink roller and a secondposition where it contacts the inner periphery of the drum and ink roller.An ink collecting member is located downstream of the ink replenishingroller in the direction of rotation of the print drum and movable ininterlocked relation to the ink replenishing roller. The printer iscapable of surely removing excess ink from the inner periphery of theprint drum and desirably forming even the first image after a long time ofsuspension. The ink collecting member is interlocked to the inkreplenishing roller and has its edge initially spaced from the innerperiphery of the print drum, so that friction between the ink collectingmember and the inner periphery of the print drum is obviated. In addition,ink is prevented from being collected more than necessary. Consequently,there can be obviated noise and short image density.
