Abstract

PURPOSE:To accurately project only a desired area of an image by fitting a masking device which cuts off an optical path properly rotatably by a rotating means nearby a film. CONSTITUTION:An image projecting device radiates the film loaded on a carrier part 3 with light from a light source. Then its image has a desired area enlarged and projected on an image receiving body through the masking device 22 which cuts off the optical path properly and a projection lens 17. Here, if the image P is photographed slantingly to the film, if the film is loaded slantingly on the carrier part 3, or if the image P slants, the masking device is rotated by the rotating means nearby the film to make the mask area follow up the slanting image. Therefore, the image and mask area never slant to shift on the image receiving body even in said cases, and only the desired area of the image is accurately projected.
