PCT No. PCT/EP87/00632 Sec. 371 Date Jun. 15, 1988 Sec. 102(e) Date Jun. 15, 1988 PCT Filed Oct. 24, 1987 PCT Pub. No. WO88/03280 PCT Pub. Date May 5, 1988.The picture changer comprises a housing with a window and a slider member, on the actuation of which a pile of pictures housed in the changer is cyclically rearranged. To simplify construction and give the change-over movement any easy action, the process of separating the individual picture, which takes place under strong spring bias, is restricted to a short partial travel. As the change-over movement continues, the individual sheet is stiffened in the conveying direction so that it holds the remainder of the pile at a distance from the separating gap and itself is held by stop members. The change-over function can be interrupted by displacing the separating gap. |
