<p>PURPOSE:To surely transfer paper with simple constitution without paper jamming even if it has folding deflection. CONSTITUTION:The rotary shaft 15a of an idler roller 15 is not on the vertical line H passing through the rotary shaft 14a of a driving roller 14, and set downstream from the rotary shaft 14a of the driving roller 14, with respect to the paper transfer direction. For example, when a paper sheet P which is folded to A4 size from A0 size is transferred, the folding deflection part P1 at the top edge and the folding crease part P2 at first collide with a driving roller 14, and the pushing-up of the idler roller 15 is prevented. Accordingly, the revolution force of the driving roller 14 is surely transmitted to the idler roller 15 through the paper sheet P, and paper clogging is prevented.</p> |
