PURPOSE:To prevent gas accumulation without making constitution complex, by specifying the shape of a press roll on a discharge side for conveying by overlapping a photosensitive material and an original with each other for printing, and discharging accumulated gas together with the photosensitive material. CONSTITUTION:A transparent sheet 8 and a belt 5 provided with through-holes for vacuum suction which are moved by a driving and a press roller forming a conveying means convey the photosensitive material 16 and original 17 one over another to perform contact printing through a light source arranged in the conveyance path. The discharge-side press roll 10' coupling with the roll 3 is shaped in a star, etc., having notched parts 15, which stride over a accumulated gas 14 to discharge the gas. Consequently, the gas is prevented from being accumulated between the photosensitive material and original without complex constitution to perform excellent contact printing processing successively. |
