PURPOSE:To reduce both any loss time at the time of both-face copy and the jam of form at the time of refeeding the form by placing, at the open end of a transport route, a sheet belt which takes in a plurality of transfer sheets from each of the front ends sequentially as if bricks are built up, and which rewinds them from each of the rear ends and makes them inverted. CONSTITUTION:A sheet belt 31 which functions as an intermediate tray is located at the open end of a transport route 26 formed by transport rollers 21, 22 and 28 and guide boards 23 and 24. The sheet belt 31 is formed in the inverted form of S by connecting a winding part 32 which takes up and takes back a transfer form 25 to a winding part 33 which turns in the reverse direction to take up and take back the sheet belt 31 itself. In such constitution the transfer form 25 is taken in from the front end thereof at the part of the sheet belt 31 and then taken back from the rear end. As a result, the form is delivered to the transport route 26 in the inverted state so that the high speed both-face copy may be enabled. |
