Master making device and stencil printer using the same
A stencil making device of the present invention includes a front tension roller pair located downstream of the nip of a thermal head and a platen roller for applying tension to a stencil. The front tension roller pair is made up of an upper roller formed of rubber and a lower roller formed of metal. The lower roller is formed with a plurality of groove portions spaced from each other in the axial direction and each having a small diameter not contacting the stencil. The groove portions therefore reduce the area of contact with the stencil for thereby reducing the influence of static electricity on the stencil.
