Abstract
Abstract A dual focus microfiche viewing system wherein an x-y table carries a pair of superimposed transparent fiches. A map spaced from the table bears indicia corresponding to the microimages on at least one of the fiches and is large as compared to the fiches. A dual focus lens is located adjacent the superimposed fiches and is capable of focusing on either of a pair of superimposed microimages on the fiches. A locater is movable over the map to produce corresponding movement of the pair of fiches relative to the lens, such corresponding movement being produced by a pantograph having an input end connected to the locater and having an output end connected to the table. The input end of the pantograph is movable through relatively large distances proportional to the size of the map while the output end is movable through relatively small distances proportional to the size of the fiches. By positioning the locater over a desired indicium on the map, a corresponding pair of superimposed microimages is positioned in the field of the lens. In some embodiments, the x-y table carries two pairs of superimposed transparent fiches either of which may be moved relative to the table into the field of view of the lens. The map is capable of corresponding movement to bring a corresponding set of indicia thereon into view through a windowed plate. In one embodiment, the fiches of each pair bear related information and the map is movable between two positions respectively corresponding to the pairs of fiches. In another embodiment, the fiches bear unrelated information and the map is orbitally movable between four positions spaced 90* apart and respectively corresponding to the four fiches. In one embodiment of the invention, one microimage of each superimposed pair bears a transportation schedule from point A to point B and the other microimage of such pair bears a transportation schedule from point B to point A.
