<p>PURPOSE:To smoothly carry out transport and intermediate stack of recording paper sheets during double sided recording and to precisely and stably guide the recording paper sheets by inverting the recording paper sheets carried in a carrying path below the bottom part of an intermediate tray upward and feeding them to the intermediate tray through a guiding means. CONSTITUTION:When a copying set to a double sided copying mode is started, leading and one side copied paper sheet passes carrying rollers 131, 132, 133 via paper sheet feed and carrying processes, then presses a branch plate upward, is housed in an intermediate tray 110 from a paper sheet feed and deliver means. Subsequently, succeeding paper sheets P2, P3 are also sequentially piled on the upper face of the preceding recording paper sheets in the intermediate tray 110. At this time, a feed roller 122 is driven in rotation in a reverse direction and the lock of a reverse roller 123 is released to be free and comes into contact with the feed roller 122. Then, it is driven in its counterclockwise rotation. Recording paper sheets fed by these feed rollers 122, 123 are sequentially stored in the intermediate tray.</p> |
