Abstract: 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. The device has discharge rollers disposed on an upper side and pinch rollers disposed on a lower side. The discharge rollers discharge a document as well as guides it to the reverse path by reversing it while claming the rear end thereof. The pinch rollers are fixed, and the discharge rollers are separated therefrom approximately upward about a rotation shaft of a transport unit. For this purpose, the discharge rollers are pressed against the pinch rollers and separated therefrom by a cancel lever. A drive system has two transmission routes one of which is reversed through a torque limiter and the other is reversed through an electromagnetic clutch.
