Abstract: A cutter for cutting a thin material by engagement between a movable blade and a fixed blade comprises a spring member which is disposed between the movable blade and a movable base for moving the movable blade in the direction of engagment and is adapted to urge the movable blade in a direction perpendicular to the linearly reciprocal motion of the movable base so as to bring the movable blade into contact with the fixed blade.

Abstract: An apparatus for automatically winding up a photographic paper that has been photographically processed onto a take-up spool is arranged such that the leading end portion of the photographic paper is passed through the area between a pair of guide plates so as to be guided to the outer periphery of the take-up spool and is then wound up onto the spool while being pressed against the outer periphery of the spool by means of rollers respectively mounted on a pair of guide arms. These guide arms expand or separate from each other in accordance with increase in the diameter of the roll of photographic paper being wound up onto the spool.

Abstract: A photographic printing apparatus has a supply spool with a flange which is movable in the lateral direction of the photographic paper to be used, a guide roller with a flange which is movable in the lateral direction of the photographic paper, a printing section, and a take-up spool with a flange which is movable in the lateral direction of the photographic paper. The supply spool, the guide roller, the printing section and the take-up spool are disposed in series. A continuous photographic paper wound in layers is loaded on the supply spool and is transported to the printing section through the guide roller, and the photographic paper printed therein is then wound up onto the take-up spool.
