In perforating a stencil sheet, platen motor and feed motor are driven and thermosensitive perforation of the stencil sheet is started. From the state, the platen motor is driven continuously for γ second. When upstream side stencil sheet awaiting sensor is made ON and α second has elapsed, speed of platen motor is controlled to reduce and actual perforation speed is made constant. Thereafter, when downstream side stencil sheet awaiting sensor is made ON and α second has elapsed, feed motor is made OFF and stopped and lower side movable guide plate is moved to lower limit position by driving downstream side movable guide motor. Thereafter, when downstream side movable guide plate lower limit sensor is made ON, feed motor is made ON and driven again. When downstream side stencil sheet feed sensor is made ON and δ second has elapsed, feed motor is made OFF and stopped.
