Abstract

PURPOSE: To make interlocking mechanism simple and eliminate the disturbances of images by keeping the speed ratio of a mirror and a projection face always at 1:2 irrespective of varying magnifications.
CONSTITUTION: The image of a subject 1 is projected by a projecting lens 2 to a mirror 6, is reflected by other mirror 7, and only the image passing a slit 10 reaches a projection face 3, whereby printing is accomplished. When the mirrors 6, 7 move to positions 6a, 7a, the optical path 8a corresponding to their reflection angles is passed through the slit 10 and copying is carried out on a photosensitive material which moves along with the movement of a flat plate 3a or drum 3b moving at a twice faster speed in the same direction as that of said optical path 8a with respect to its movement, and when the optical path 8b by the change in the reflection angles like the mirrors 6b, 7b, successively ends moving over the entire surface of the subject 1, the copying ends. If it is desired to increase the magnification, the lens is exchanged with a projection lens for wide angles.
