ABSTRACT:
A photographic processing apparatus capable of printing films having different widths. An exposure unit for printing film images on photographic paper has a negative mask to guide the movement of the films. The negative mask is provided with a plurality of film guide paths which correspond to widths of the films. A transfer unit is provided to move the negative mask in a direction perpendicular to the feed direction of the film. Along the film feed path toward the negative mask are provided sensors to detect the film size. Printing is carried out in such a manner that after the film size has been detected by the sensors, the transfer unit is controlled by the signal from the sensors to bring one of the film guide paths which corresponds to the film size into alignment with the exposure axis.
