HAND HELD MICROFICHE VIEWER ABSTRACT OF THE DISCLOSURE The microfiche card has micro images arranged in horizontal rows and vertical columns. The card is inserted into the slots at the fronts of the sides of the housing and can be moved to align the desired column with the lens. The lens is vertically movable on the front of the housing and can be aligned with the desired row of images. The back of the housing has a light gathering lenticular panel which transmits light into the light chamber where it is diffused and illuminates the light diffusing (Opal) glass and the micro image. Under low ambient light conditions the switch on the handle may be depressed to illuminate the bulb in the light chamber. The handle houses the batteries which power the bulb. The focal length of the ocular is selected to provide the proper magnification of the image to make the image readable. 1.
