A film driving assembly includes a second casing having a detachable bottom removably positioned on the top surface of the first casing. A light-transmitting window is defined in the bottom, having a length and a width. A film driving mechanism is arranged inside the second casing, including a film container for containing a length of film and a film spool for windingly receiving the film roll, respectively arranged on opposite longitudinal ends of the window. A motor drives a toothed wheel engaging perforations defined in the film for moving the film across the length of the window. A light source projects light through the film and the window toward the optical scanning module for performing scanning operation of the film.
