ABSTRACT:
In a stencil printer, a first conveyor portion conveys a stencil master toward a printing drum and includes a rotatable platen roller which rotates to convey the stencil master pinched between the platen roller and a thermal head and associates with the thermal head to thermally make a perforating image on the stencil master. A second conveyor portion which is disposed between the first conveyor portion and the printing drum and conveys the stencil master toward the printing drum. When making the perforating image on the stencil master, the first conveyor portion operates at a first speed with the second conveyor portion stopped or operated at a low speed after the leading end of the stencil master is delivered to the second conveyor portion. When conveying the leading end of the stencil master, on which the perforating image has been made, toward a master clamping mechanism disposed on a generatrix of the printing drum, the second conveyor portion operates at a second speed lower than the first speed with the first conveyor section stopped.
