Abstract: A stencil printing apparatus for wrapping a master around an outer circumferential surface of a plate cylinder to perform printing, the stencil printing apparatus being capable of preventing the occurrence of abnormal images or afterimage phenomenon which causes confidential information leakage, without increasing cost or causing any problems. This stencil printing apparatus has time measuring means for measuring a leaving time during which the apparatus is left stand, and when a plate discharge command is output before the leaving time exceeds a first predetermined time while the master is wrapped around the outer circumferential surface, the stencil printing apparatus is shifted to a standby state after the master is discharged from the outer circumferential surface.

Abstract: In a stencil printing apparatus capable of duplex printing, in which a front surface printing process for printing a front surface image on one surface of a sheet of paper fed by a sheet feeding unit is performed, the sheet is re-fed to a sheet re-feeder, and then a rear surface printing process for printing a rear surface image on the other surface is performed. The positions of the front surface image and rear surface image to be formed on the sheet can be moved together by a predetermined amount in a single direction side of a sheet conveyance direction.

Abstract: In a stencil printing apparatus capable of duplex printing, in which a front surface printing process for printing a front surface image on one surface of a sheet of paper fed by a sheet feeding unit is performed, the sheet is re-fed to sheet re-feeding means, and then a rear surface printing process for printing a rear surface image on the other surface is performed, the positions of the front surface image and rear surface image to be printed on the sheet can be moved together. The stencil printing apparatus comprises: a printing unit having a printing cylinder and pressing means; the sheet feeding unit for feeding the sheet toward the printing unit; and the sheet re-feeding means for temporarily accommodating the sheet after a printed image is formed on the front surface thereof in the printing unit, and then re-feeding the sheet toward the printing unit.
