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.
Abstract: 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fingers extend in a direction perpendicular to the forward direction that the selected sheet is moved upon being withdrawn from the stack.
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.
