Abstract: The invention relates to a container for a pile of sheets essentially of like format with a housing (12), which has a viewing window (35) exposing to view the uppermost sheet in the pile, and with a slider member (14), which can be pulled out of the housing parallel to the plane of the window, having a front wall (61) essentially flush with one edge of the housing, which wall is joined by side-pieces (44) to a slider member rear wall (20), as well as a grip arrangement (56, 57) that fits-in in the direction of the window (35) from the front wall (61) and comprises a grip top plate or wall part (56) and a grip bottom plate or wall part (57), the outer faces of which are essentially flush with the surrounding outer faces of the housing, and having at least one housing part (627) that extends parallel to the or one of the grip plates and, when the slider member (14) is in the pushed-in state, is covered by this grip plate (57).

Abstract: A device for cyclically rearranging a pile of rectangular or square sheets (such as photographic prints) by repeatedly performing the operation of removing one sheet from one end of the pile and returning the removed sheet to the other end of the pile. To facilitate removal of each sheet from the pile, the sheet to be removed is pressed against a frictional surface by a roller on the separator structure which moves relative to the sheet to be removed in order to separate that sheet from the remainder of the pile. The frictional surface moves with the sheet to be removed, and the roller helps ensure that the sheet to be removed stays in contact with the frictional surface and is moved thereby.

Abstract: Apparatus for the cyclic rearrangement of a pile of rectangular or square sheets, especially a pile of photographic prints, is provided. The apparatus has a first and a second frame part which may be moved relative to one another and parallel to the main plane of the pile, and a picture changer which, on movement of the frame parts backwards and forwards, removes an individual sheet at one end of the pile and adds it to the other end of the pile. The picture changer includes a first and second separating member which, resiliently biased towards each other, define a through-gap which for the entry of the sheet being separated has a spacing greater than the thickness of one sheet and less than the thickness of two sheets, which spacing is, during the outward movement of the frame parts, maintained or reduced to the thickness of the sheet being separated, as appropriate.

Abstract: 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 t

Abstract: A device for the cyclic rearrangement of a pile of rectangular sheets, especially photographic prints. The device includes first and second frame parts (12, 14), of which one has a viewing window (35) in front of a principal face of the pile. The frame parts can be pulled away from each other and pushed back together again parallel to the plane of this face. A single sheet is removed from one end of the pile when the frame parts are pulled away from each other and returned to the other end of the pile when the frame parts are pushed together. During its movement relative to the window, the sheet facing the window is held spaced from the window by elements on the frame parts which are arranged and designed so that they overlap all edges of the picture but nevertheless render possible the passage of the picture through the gap defined by those elements.

Abstract: A container for accommodating a pile of pictures, having a picture exchanging mechanism, is provided. The container has a window under which the pile of pictures is held in a viewing and storage position. At least one picture in the pile can be pulled out on a slider member such that when the slider member is pushed back in, the at least one picture is returned to the other end of the pile, so that a different picture can be viewed in the window. A hold-down member which prevents the withdrawn picture or pictures from falling out of the slider member while the slider member is pulled out is at least partially retracted when the slider member is pushed back in, so that it is not visible in the window.

Abstract: Disclosed is a picture viewer for viewing a stack of pictures sequentially through a viewing window. The picture viewer comprises a housing member, a slider member, a bias means for urging the stack of pictures against the viewing window, and an exchange means for sequentially changing the picture that is presented at the viewing window. The exchange means comprises: (a) a retentive element to hold one picture in the housing member when the slider member is moved out of the housing member and (b) a separator bar which pushes the remainder of the stack out of the housing when the slider member is moved out of the housing. To permit relatively smooth operation of the picture viewer, the bias means is mounted on the slider.
