Abstract
The photographic projector is adapted that a lens seating plate to which a projecting lens is fixed is provided so that it maybe moved in the optical direction with respect to the lens holder. When the base of the lens holder reaches even to the end of its stroke, distance of the original picture or that of the picture image from the base of the lens holder is still deficient in reaching to the value which corresponds to desired magnification, the lens seating plate is moved a desired amount along the optical axis so that the lens may be set up a position corresponding to any desired magnification.
