Abstract: A stencil printing apparatus allows printing on coated paper as in ordinary paper (uncoated paper), and can make a contribution to the diversification of printing needs. The stencil printing apparatus comprises a printing apparatus body comprising a printing drum having UV curable ink, and an UV irradiation device connected to a paper output unit of the printing apparatus body. When the paper type is recognized as coated paper on the basis of a signal from paper type input means or the like, control means controls a master-making energy supplied to a thermal head serving as master-making means, to be larger than a master-making energy supplied in the case of uncoated paper. The paper onto which an ink image corresponding to the characteristics of coated paper has been transferred is then fed into the UV irradiation device, where the ink is dried and cured.

A first shift display section displays an amount of shift of the position adjusted by the first adjusting section. A first moving mechanism shifts the position of the stencil image in accordance with the operation of the first adjusting section. A second shift display section displays an amount of shift of the position adjusted by the second adjusting section. A second moving mechanism shifts the position of the non-stencil image in accordance with the operation of the second adjusting section.

Abstract: A master roll includes a cylindrical core, a long-formed stencil wound around the core, and a ring-like identity member inserted in at least one side of inner periphery of the core. The identity member has a feature according to a variety of the stencil. The feature of the identity member is identified by size of the identity member, inserted position of the identity member or the like, so that many varieties of the master roll can be easily manufactured. A master roll holding apparatus can hold the master roll.

Abstract: A stencil printer includes a multistage paper feeding device capable of selectively feeding different kinds of papers and an ink drum shiftable in a direction perpendicular to a direction of paper conveyance, i.e., in the widthwise direction of a paper. A paper is conveyed along a path coincident with a center line connecting the coincident centers of paper stocking portions included in the paper feeding device and the center of a paper discharge tray, so that the paper can be accurately conveyed without any skew. Further, side fences provided on the paper discharge tray are interlocked to each other and movable in the widthwise direction of a paper symmetrically with respect to the center line of the transport path, neatly laying the paper on the tray between the side fences. In addition, the ink drum shiftable in the above direction allows an image position to be adjusted without varying the paper transport path.

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.

Abstract: A printer for printing an image on a paper paid out by a pick-up roller and separated from the other papers by a separating device includes a kind-of-paper setting device for allowing the operator of the printer to select and input the kind of papers to be used. A controller automatically selects, among transport conditions stored beforehand in correspondence to the kinds of papers, optimal transport conditions matching with the kind of papers input by the operator in response to a signal received from the kind-of-paper setting device. The operator should only select and input the kind of papers while watching an LCD (Liquid Crystal Display) provided on an operation panel. The printer obviates troubles relating to the transport of papers.

Abstract: A paper feeder for feeding papers to an image forming apparatus and a paper tray elevation device therefore are disclosed. A first tray is movable up and down with a plurality of papers stacked thereon. A paper feed member feeds the papers from the first tray in a preselected direction of paper feed. A second tray is positioned beside the first tray in substantially the horizontal direction and movable up and down with a plurality of papers stacked thereon. A shifting device shifts the entire paper stack from the second tray to the first tray. A horizontal elevating mechanism elevates the first tray while maintaining it in substantially the horizontal position. An interlocking mechanism at least elevates, when papers of greater in size than the papers to be stacked on the first or second tray are stacked over the first and second trays in a single stack, the second tray in interlocked relation to the elevation of the first tray while maintaining the second tray in substantially the horizontal position.
