Abstract
A stencil printing machine includes a thermal head for perforating a stencil sheet; a platen roller situated adjacent to the thermal head, the platen roller conveying the stencil sheet in a predetermined direction while holding the stencil sheet in contact with the thermal head; a printing drum situated near the thermal head and the platen roller, the printing drum being adapted to receive the stencil sheet perforated by the thermal head and the platen roller; and a discharging member situated near the platen roller on a downstream side of the predetermined direction relative to the thermal head and the platen roller, the discharging member discharging static electricity charged on the stencil sheet.
Claims5
A stencil printing machine comprising:
- a thermal head for perforating a stencil sheet;
- a platen roller situated adjacent to the thermal head, said platen roller being adapted to convey the stencil sheet in a predetermined direction while holding the stencil sheet to contact the thermal head;
- a printing drum situated near the thermal head and the platen roller, said printing drum being adapted to receive the stencil sheet perforated by the thermal head;
- and
- a discharging member situated near the platen roller to be spaced apart therefrom on a downstream side of a moving direction of the stencil sheet, said discharging member being disposed on a side of the platen roller and directed to the stencil sheet so that the discharging member is adapted to contact a lower side of the stencil sheet passing between the thermal head and the platen roller, said discharging member configured to support the stencil sheet to prevent the stencil sheet from curling around the platen roller and to discharge static electricity charged on the stencil sheet.
