PURPOSE:To always obtain an output picture at a normal position by providing an oblique running detecting part, an arithmetic part calculating a feeding condition for returning a paper in the normal position form an oblique degree, and an oblique running correction part receiving correction information of the arithmetic part and adjusting feeding speed on both sides of an original, and correcting the oblique running of feeding. CONSTITUTION:When the original 4 is inputted to an equipment from an operator, the feeding of the original 4 is started by feeding rollers. When the tip of the original 4 is inputted to the original passage part 5, photo sensors 6 and 7 detect the degree of obliquencess. Information of the oblique running detection part 1 is transmitted to the operation part 2, which calculates the correction value. The operations part 2 transmits the correction value to the oblique running correction part 3. Said part 3 adjusts the rotational frequency of either of the rollers 10 and 11 in driving parts 8 and 9, and corrects feeding. A correcting action is executed until the tip of the original 4 attains vertical with respect to the direction of the movement of the original 4. After the original is corrected, the rollers 10 and 11 rotate with the same rotational frequency.
