PCT No. PCT/EP85/00616 Sec. 371 Date Jul. 11, 1986 Sec. 102(e) Date Jul. 11, 1986 PCT Filed Nov. 12, 1985 PCT Pub. No. WO86/03030 PCT Pub. Date May 22, 1986.The invention relates to a device for the cyclic rearrangement of a pile of rectangular or square pictures, with a first and a second frame part (12, 14), which can be moved back and forth parallel to the principal plane of the pile of pictures held by them, with a separator bar (20), arranged in the second frame part (14), which defines a separating through-gap for a picture and a return through-gap for the picture, with a retaining element in the first frame part (12) for retaining a picture taken from one end of the pile and guided through a separating through-gap, and with a guide element for shifting the retained picture transversely to the pile and returning it through the return through-gap to the other end of the pile, and with a viewing window (35) in one of the frame parts (12), wherein the two frame parts (12, 14) are coupled by way of a free-wheel-type device which, when the two frame parts (12, 14) are in the end position where they are pulled completely apart, frees the return movement and, in the end position where they are pushed completely together, frees the withdrawal movement, but when there is a change in the direction of movement blocks this at least in the two respective areas of reversal of withdrawal and return movement adjacent the two end positions.
