Abstract:
Apparatus is disclosed for viewing a preselected one of a plurality of information-bearing media, such as microfilm in fiche format, from a container housing a plurality of such media. The apparatus includes a frame, with the frame having a viewing area associated therewith; first means operatively associated with the frame for moving a container housing the plurality of information-bearing media between a first and second position which includes the viewing area therebetween; and selection means for retaining a preselected one of the media in the viewing area when the container is moved from the second position back to the first position. Each medium in the container includes a trailing border portion and the length of travel of the container between its first and second positions is less than the total length of the medium such that the trailing border portion remains interleaved between remaining ones of said plurality of media when the carriage returns to its initial first position. In this manner, a medium which has been selected for viewing can be easily returned into its container. The entire frame is movably mounted on a support structure for motion in transverse directions with respect thereto such that a desired "row" and "column" frame on the information-bearing medium can be properly positioned with respect to a light source positioned therebeneath.
Apparatus For Removing A Sheet From A Stack Of Sheets
Apparatus is disclosed for removing any sheet selected from a stack of sheets without removing adjacent unselected sheets in the stack. The apparatus includes means for selecting and withdrawing the desired sheet in a forward direction from the lead end of the stack, and support means, such as a plate, arranged adjacent to the stack of sheets. Mounted on the plate are sheet-engaging means in the form of a pair of buckling fingers, which extend alongside the lead end of the stack and are adjacent the stack corners. The buckling fingers extend in a direction perpendicular to the forward direction that the selected sheet is moved upon being withdrawn from the stack. The buckling fingers serve a dual purpose: they are operable to resist the forward movement of the unselected sheets as they are withdrawn with the selected sheet; and they are also operable to apply a force against the sides of the selected sheet to buckle it as it is being withdrawn in the forward direction from the stack by the selecting means and past the buckling fingers. The buckling of the selected sheet overcomes the forces tending to maintain the selected sheet in contact with the adjacent unselected sheets which forces include frictional drag, electrostatic adhesion, and inertia. By overcoming these forces, the selected sheet, when buckled, can be easily withdrawn from the stack without removing the adjacent unselected sheets.

Abstract:
Apparatus is provided for viewing a preselected one of a plurality of information-bearing media, such as microfilm in fiche format, from a container housing a plurality of such media. The apparatus includes a viewing area and clamps for removably receiving the microfilm container. Selection apparatus is provided for selecting one of the media from the container and moving it to the viewing area while the container is held in position on the frame. A movable carriage is provided for moving the selection apparatus and the selected media from the container into the viewing area.
