A scanning apparatus for scanning an object includes a casing, a scanning module, at least one sensor, and a control unit. The control unit is electrically connected to the scanning module and the sensor for receiving a detecting signal generated by the sensor so as to actuate the scanning module to scan, and the scanning module then generates a first image of a first scanned page and a second image of a second scanned page. The control unit further includes a recognition unit for recognizing whether the first image along with the second image are continuous. As the recognition unit recognizes the first image and the second image to be discontinuous, the control unit generates an insertion image between the first image and the second image.
