Abstract:
1. A photographic film driving device mounted on an image scanning device capable of scanning an image of a photographic film, comprising: a casing removably mounted on the image scanning device, including a detachable bottom plate; a light-transmitting window including a length and a width, defined in the bottom plate; a film container capable of containing the photographic film comprising a series of successive frames, the film including a width substantially corresponding to the width of the light-transmitting window, wherein the film container is disposed adjacent to a first side of the light-transmitting window; a guide disposed adjacent to the film container; a film driving mechanism comprising a motor to which a toothed wheel and a drive pulley are coupled, wherein the motor is capable of rotating the toothed wheel and the drive pulley, wherein the toothed wheel is capable of engaging the film and capable of driving the film in a predetermined direction across the length of the light-transmitting window, and wherein the film driving mechanism is disposed adjacent to a second side of the light-transmitting window; a film receiving device capable of receiving the film driven by the film driving mechanism from the film container, the film receiving device mechanically coupled to the motor of the film driving mechanism by a drive belt and a secondary pulley, wherein rotation of the film receiving device via the motor of the driving mechanism is capable of winding the film on the film receiving device; and a light source capable of emitting a light that transmits through the frames of the film present on the light-transmitting window to project images of the frames onto the image sensing device.
