<p>PURPOSE:To facilitate maintenance and at the same time miniaturize a sheet turning-over device by considering the arrangement of a transport drive system and a drive force transmission unit in the sheet turning-over device, arranging in division a forward rotation drive system and a forward/backward rotation drive system. CONSTITUTION:In the case of a sheet turning-over device equipped with a casing portion and a sheet turning-over unit that is loaded into the casing portion so as to be able to be drawn out, a drive system to transport sheets to a turning-over path and a re-paper feed path is divided into two. In addition, the members 437, 438, 439 of a forward rotation drive system are arranged on one side of the sheet turning-over unit 407, and the member 449 of a forward/ backward rotation drive system is arranged on the other side, and in the rear of the forward/backward rotation drive system, a drive force transmission unit 450 which transmits drive force to both of the drive systems at the time of the sheet turning-over unit being loaded and cuts off drive force at the time of being pulled out, is arranged on the casing portion 406 side.</p> |
