Abstract
PURPOSE: To enlarge and print the panoramic photograph continuously, by disposing slits just before the specified distance corresponding to the magnification across a lens for enlargement, and feeding the photographic paper in the reverse direction of the film at a feed speed proportional to the magnification with respect to the feed speed of negative film.
CONSTITUTION: A slit for negative film 3 and a slit for photographic paper 4 are disposed in upper and lower positions across a lens for enlargement 2 in a dark box 1, and a negative film 5 is sent by a feed roller 7 in the direction of arrow 6 at the position of distance a upwards from the center S of the lens for enlargement 2. At the position of distance b downwards from the center S of the lens for enlargement 2, a photographic paper 8 having the width corresponding to the magnification is sent in the direction of arrow 9 in the reverse direction of feeding the negative film 5 at a feed speed proportional to the magnification with respect to the feed speed of the negative film 5 by means of the feed roller 10. As a result, the relative speed of the photographic paper 8 and magnified image becomes zero, so that the magnified image passing through the slit 4 is clearly photographed on the photographic paper 8. Thus, continuous enlargement of panoramic photographs or continuous printing of frame pictures may be realized.
