Abstract

PURPOSE: To prevent copying deviation of photosensitive paper and original drawing by making the tension of belts other than photosensitive paper width weaker than the tension of the belts of the photosensitive paper width at the time of pressure contacting the plural conveying belts having a built-in light source, superposing and inserting the original drawing and photosensitive paper and printing and conveying the same.
CONSTITUTION: A plurality of conveying belts 2 are pressure contacted to a cylinder drum 1 having a built-in light source and an original drawing and photosensitive paper are superposed and inserted between the belts and drum 1, whereby these are printed and conveyed. Paper width detecting microswitches 10 are provided in the paper conveying path of the belts 2. The operations of the switches 10 cause the solenoids 12 of the tension rollers 11 provided to the respective belts corresponding to these to turn OFF, thus loosening the tension rollers 11 like dotted lines and the belts other than for paper width like dotted lines. Thereby, the deviation action between the photosensitive paper and original drawing in the cylinder drum winding part is eliminated and the deviation and out-of-focus of the copy are surely prevented.
