A document transport moves the documents at a high speed for entrance, flip-over and exit, and at about one-fifth that speed for video scanning while moving for producing the video signal. Servo control provides a forward and back initial motion to obtain top to bottom scanning. The servo circuit is electrically protected. The video sensor is firmly coupled to the optical system.
