摘要： A stencil printing apparatus is provided, which comprises a pressure chamber having a first wall and a second wall both of which face each other and are built up together via a frame-like packing, said first wall comprising a frame member which has flexibility in all directions and on which a diaphragm having flexibility is extended; means for supporting a stencil so as to have the stencil disposed opposite to said diaphragm in the pressure chamber; means for supporting printing paper so as to have the printing paper disposed between the stencil and the second wall in the pressure chamber, and means for reducing pressure in the pressure chamber. The diaphragm may be extended on the frame member by laminating it onto the frame member, and the packing and the means for supporting a stencil may be installed on part of said diaphragm overlapping with the frame member. The means for supporting a stencil may be a pair of fabric fastener, one half of the pair being fixed to the frame member.

摘要： A light-curing ink fixing device comprising a light source for illuminating with fixing light the recording surface of a recording medium printed in a light-curing ink, a fixing body disposed in the carrying path of the printed recording medium, formed in a circular column, and capable of transmitting the fixing light, a carrier opposed to the fixing body with the carrying path interposed therebetween, and pressing means for nipping the fixing body and the carrier, wherein the recording medium is moved into the space between the fixing body and carrier nipped by the pressing means, the recording surface of the recording medium is brought into close contact with the fixing body, and the fixing light transmitted through the fixing body is projected onto the contact portions of the fixing body and the recording surface so as to cure and fix the light-curing ink in which the recording surface is printed.
