In a double-sided document transport device having a document reverse mechanism for suppressing the occurrence of jam and deterioration of read image, after a document is transported to a reading position, it is transported to the reading position again to read a rear side thereof through a reverse path. In some cases, the front plate may have a recessed portion that is recessed back toward the rear plate and align with the aperture in the rear plate. The second output is coupled to the first output through a series resistance element. System components are mounted to the second passivation layer and electrically connect to the second conductive layer.
