6191 ABSTRACT OF THE DISCLOSURE A microfiche system for recording a regular pattern of micro image frames on a transparency film unit, preferably of the self-developing type, and thereafter for projecting enlarged images of the recorded frames for viewing. The system includes as separate cooperable components a microfiche camera, a microfiche projector and a console. The console includes a combination document mounting glass and image display screen area, a camera/projector mount for alternatively receiving the camera or projector and a pair of mirrors for transmitting images between the mounting and display area and the mount. For recording the camera is located on the mount and incrementally movable camera exposure and film advance mechanisms provide the capability of recording an orthogonal pattern of images of documents supported successively on the document mounting glass. After film processing, the system is converted for viewing by replacing the camera with the projector and locating the image display screen over the mounting glass. The projector includes a mechanism for moving the film unit relative to a projecting lens for projecting an image of any micro frame on the film unit onto the image display screen.
