PURPOSE:To ensure the separation of an original drawing paper from a photosensitive paper by sucking air between opposite air-hole faces alternately. CONSTITUTION:A pair of guide-boxes 10 with air-holes are respectively provided with shield plates 15a and 15b to intercept air streams, and positions of the shield plates are optionally changed. Thereby, suction forces are optionally caused in the guide boxes 10 with air-holes, and necessary suction forces are generated and removed in accordance with the progressing state of an original drawing paper A and a photosensitive paper B. This construction permits to ensure the separation of the original drawing paper from the photosensitive paper. |
