A device for cyclically rearranging a pile of square or rectangular photographic sheets comprises a first and a second frame parts (12, 14) movable according to a reciprocating motion with respect to each other and in parallel to the main plane of the pile contained therein. A separator bar (20) arranged in the second frame part (14) forms a separator passage for separating a photographic sheet and a passage for returning the photographic sheet. A holding device in the first frame part (12) holds a photographic sheet separated from the pile of photographic sheets, pulled from one side and brought through a separation passage. A guiding device displaces the held picture transversally to the pile of photographic sheets and brings it back by the return passage to the other side of the pile. A visualization window (35) is provided in one of the frame parts (12). The two frame parts (12, 14) are coupled by means of a free run device which allows both frame parts (12, 14) to freely move from their extreme positions whether to return from the position wherein they are completely separated or to perform a separation motion from the position wherein they are completely engaged. The free run device locks their return and separation motion upon a change of direction at least in the two reverse areas before the extreme positions. |
