PROBLEM TO BE SOLVED: To prevent a printing surface from being stained and a drum from being stuck with due to the usage of a separating claw and prevent image variations from developing due to separating timing variations of printing paper. SOLUTION: In stencil printing equipment, which has a drum 21, on which a base stencil paper is installed, a press roll 23, which presses the printing paper 30 to be fed between the drum and the press roll in order to transfer images from the base stencil paper on the printing paper during the passing process of the fed printing paper between the drum and the press roll and finally deliver the printing paper, on which the images are transferred, to the downstream side in the conveying direction of the press roll, a suction nozzle 41 is provided movably between the sucking position near the outer peripheral surface of the drum and a carrier orbital position, which locates nearly in the same height as that of a carrier passage and further a suction fan 47 for sucking outside air of the drum side through the suction nozzle is provided in order to energize the sucking position side and, at the same time, a spring 44 having an energizing force, which is weaker than a sucking force action on the suction nozzle under the state being blocked by the printing paper, is provided.
