(Abstract of the disclosure) 1) In the present invention, displacement of lens of photographic printing apparatus is made possible with the result that the said lens is positioned at regular position when printing is to occur, while in operations other than photographic printing,the said lens is evacuated to a position far from the negative film so that lensprotection and adjustments are easier. 2) In the present invention, a sample-print detector apparatus that consists of CCD cameras, line sensors and the like measures the shift in the center of exposure,and the correction required is automatically registered. 3) In the present invention, by rotating negative mask member, lens member andexposure station by an identical angle of rotation, a predetermined angle of exposure can be obtained. In addition, added to the motion by rotational mechanism, by minutely sliding the lens, a 3D photographic apparatus of greater accuracy is constituted. 4) In the present invention, by incorporating means of displacement into the enlarging lens and exposure station, printing by trimming is executed. 5) In the present invention, a photographic paper cut by a cutter is machined for removing wastes on the frontal region of the leading edge of the photographic paper by an edge-shaper that functions in the direction perpendicular to the progressing direction of said photographic paper, and the wastes removed are sent to a waste-box by a suction mechanism.
