Stencil printing machine

A stencil printing machine, comprising:

• a rotationally driven drum, in which a stencil sheet is mounted on an outer peripheral surface;
• a pressure roller which presses a print sheet fed to between the drum and the pressure roller and rotates together with the drum, in which the print sheet is fed from an upstream side of the pressure roller in a conveying direction to between the drum and the pressure roller, an image is transferred from the stencil sheet onto the fed print sheet in a process where the print sheet passes between the drum and the pressure roller, and the print sheet on which the image is transferred is discharged to a downstream side of the pressure roller in the conveying direction;
• a suction port forming plate which is provided at a position close to a downstream peripheral surface of the pressure roller in the conveying direction and has a sheet conveying surface, in which a suction port is formed between the peripheral surface of the pressure roller and the suction port forming plate;
• and
• a suction fan which sucks air on an outer side of the sheet conveying surface from the suction port
• wherein the pressure roller is freely movable between a press position of pressing the drum and a standby position of being spaced from the drum, the suction port forming plate is provided to be freely movable together with the pressure roller and
• wherein effective width of the suction port is larger than the maximum width of the print sheet feedable.
