<p>PROBLEM TO BE SOLVED: To provide a scanned image calibration device and calibration method.SOLUTION: A scanned image calibration device and calibration method includes: a scanning unit mounted on a paper feeding path, and configured to scan a document which passes; a first paper feeding roll disposed on the upstream of the scanning unit; and a second paper feeding roll disposed on the downstream of the scanning unit. Any other paper feeding roll is not disposed between the first power feeding roll and the second paper feeding roll, and a distance between the first paper feeding roll and the second power feeding roll is smaller than the length of the document. A sensor unit is disposed on the paper feeding path, and configured to detect the position of the document and a distance between the front and rear documents. The control unit is connected by an electric signal to the sensor unit, and configured to control the rotational speeds of the first power feeding roll and the second power feeding roll in accordance with a signal generated by the sensor unit. Thus, it is possible to prevent the change of the feeding speed of the document by adjusting the rotational speed of the paper feeding roll in a real time in accordance with the detection of the document position.</p> |
