孔版印刷装置
Document Type and Number:
Japanese Patent JP4410352
Kind Code:
B2
Abstract:
A stencil printer of the present invention includes a porous hollow cylindrical print drum rotatable with a perforated master having a porous resin film as a base wrapped therearound. A pressing member is selectively movable into or out of contact with the print drum for pressing a paper or similar recording medium fed from a paper feeding device against the print drum. As a result, ink is transferred from the inside of the print drum to the paper via perforations formed in the master. The pressing member is implemented as a roller having a plurality of layers including an inner layer having a hardness of 8° to 14° (JIS (Japanese Industrial Standards)-A) and an outer layer having a hardness of 30° to 40° (JIS-A). With this configuration, the entire roller has surface hardness of 18° (JIS-A) and prevents the resin film of the stencil from partly coming off due to stress ascribable to the edges of relatively thick papers.
