An apparatus is disclosed for permitting a seated operator to microfilm documents. A structure similar to an office desk has a central aperture in its top in which a transparent exposure plate is mounted and beneath which lighting tubes are mounted. A microfilm camera is mounted in an upper drawer to one side of the knee hole. Mirrors are provided to reflect the image rays toward the rear of the structure, then beside the knee hole, and ultimately to the camera. A hinged removable panel is mounted in the aperture flush with the top surface of the structure. When the panel is removed, the exposure plate moves upwardly to a flush position for receipt of the documents to be recorded.
