ABSTRACT:
In the stencil-producing apparatus of the present invention, both the stencil production and the thermal printing are possible. In the apparatus, a thermal head performs stencil production by forming dot-shaped perforations in a heat-sensitive stencil medium and prints images by forming dot-shaped images in a heat-sensitive imaging medium by heating a plurality of thermal elements aligned in a main scanning direction. During thermal printing, the pitch of the relative movement between the heat-sensitive medium and the thermal element in the auxiliary direction is set to a minimal. During stencil production, heat drive of the thermal elements is selectively precluded in the main scanning direction. Heat drive of the thermal elements is selectively precluded also in the auxiliary scanning direction. Or otherwise, the pitch of the relative movement between the thermal head and the heat-sensitive stencil medium in the auxiliary scanning direction is increased to a pitch longer than the pitch during printing. This provides spaces between adjacent dots of the resultant stencil. Stencil printing with no blurring and no set off can be achieved with such a stencil. Also, good thermal printing on heat-sensitive imaging medium with no spaces between adjacent dots during printing can be achieved.
