Patent number: 6631674Abstract: On each of plural printing drums (25, 26) in a stencil printing machine (1), a stencil sheet (11) made corresponding to printing data is rolled. The machine (1) for a stencil printing process, in which a printing paper is pressed on each printing drum and the used stencil sheet is disposed, has a mode designation section (101) and a controller (102). The section (101) designates whether or not a stencil printing process is performed for plural printing information including common printing data. The control section (102) controls the stencil making process, the stencil disposing process, and the stencil printing process for the printing information. When the printing information includes common printing data, the controller (102) controls the printing drum on which the stencil sheet for the common printing data is rolled so that the stencil making and disposal processes are not performed.Type: GrantFiled: July 27, 2001Date of Patent: October 14, 2003Assignee: Riso Kagaku CorporationInventors: Yoshikazu Hara, Takeshi Koishi
