Abstract

The automatic document feeder includes an upper scan module and a paper delivery path. The upper scan module includes a scanning unit and a scanning platform. The paper delivery path is configured below the upper scan module. The scanning platform is arranged between the scanning unit and the paper delivery path. The paper delivery path transports the paper through the scanning unit and flips it over. Since the paper delivery path is arranged below the upper scan module, the paper may pass through the scanning unit as soon as it begins to traverse a partial range of the paper delivery path, eliminating the need for the paper to traverse most of the paper delivery path before reaching the scanning unit. By configuring the components and designing the passage of the paper delivery path, the time taken for the paper to pass through the paper delivery path may be shortened.
