Abstract
In an apparatus for developing a picture on a sheet of developing paper from an exposed sheet of photo-sensitive material by pressing together the sheets of developing paper and photo-sensitive material, and in which such sheets in contact with each other are intermittently transported in a predetermined direction of sheet travel across a back-up surface, and a rotatable roller having its axis of rotation extending substantially at right angles to a longitudinal median of the back-up surface is transported relative to the back-up surface in directions parallel to the longitudinal median thereof while the roller is urged toward the back-up surface with the sheets of developing paper and photo-sensitive material therebetween so as to be pressed together at a relatively narrow stripe-like area defined by the rolling path of the peripheral surface of the roller; standby surfaces extend from the opposite ends of the back-up surface and are raised relative to the latter for defining shoulders therebetween by which the sheets are guided in being transported across the back-up surface, and the roller is situated on one of the standby surfaces during the transporting of the sheets and, when…
