Abstract

PURPOSE:To prevent a sheet from falling outside an apparatus by stopping the rotation of a pair of switchback transport rollers, with a sheet projected from a discharge opening, at the time of discharging a sheet of an improper size from an opening of a re-feed device to the outside. CONSTITUTION:In a mode of both-sided copying or composite-copying a sheet inserted from a manual feed portion 32, when the size of the sheet is detected by a sensor PS3 just before a timing roller 40 and a timer, it is judged that the size is improper for re-feed, a re-feed mode is canceled to discharge a one- sided copy sheet from an opening 83 to the outside by a pair of carry-out rollers 44, a pair of transport rollers 64, and a pair of switchback transport rollers 75. In this case, the rotation of the paired transport rollers 75 is stopped at a point of time the improper sheet is still held by the paired rollers 75, with the sheet projected from the discharge opening 83. Thus, the discharged sheet of an improper size is held by the paired switchback transport rollers to be prevented from falling outside an apparatus.
