PURPOSE:To improve the efficiency of copying operation by loading plural negatives and films previously, and performing contact printing operation of each negative automatically on set conditions through the operation of a controller. CONSTITUTION:A start button is depressed after various conditions are set. A driver C2 operates firstly to move an elevation case C1 to necessary height and then a negative drawing-out device C3 operates to draw the 1st negative holder H out of the elevation case C1 to a printing surface P. At the same time, an opening and closing device operates to open light shield lids of trays D1 and E1. Then, a film feeder F operates to convey suctionally the film J as the uppermost stage in the tray D1 onto the negative on the negative holder H drawn out to the printing surface P. In this state, the contact printing of the film J is carried out through an optical device B. The exposed film J is conveyed to the tray E1. Those operations are carried out automatically and efficiently on the set conditions.
