PROBLEM TO BE SOLVED: To provide a stencil printer capable of executing one stroke double- side printing with a simple constitution while preventing occurrence of a conveying jam or a curling and obtaining a double-side printed matter of stable density and quality. SOLUTION: The stencil printer 1 comprises a first plate cylinder 28 arranged at a position corresponding to a first surface of a printing sheet P, a pressing means 29 separably provided on an outer peripheral surface of the cylinder 28, a second plate cylinder 59 arranged at a position corresponding to a second surface of the sheet P at a downstream side of a sheet conveying direction of the first cylinder, and an impression cylinder 60 separably provided on an outer peripheral surface of a second plate cylinder 59. In this case, a diameter of the cylinder 60 is the same as that of the first cylinder 28. Its rotating speed is the same as that of the first cylinder 28. Further, a distance L1 from a contact position of the cylinder 28 with the means 29 to a contact position of the cylinder 59 with the cylinder 60 is set shorter than a length L2 of the sheet of a minimum size to be used. |
