<p>PURPOSE:To make compensation for a positional slip possible to be done even in case of a sheet of paper being yieldable and different in size, by installing an attitude controller, which conveys the paper as pulling it with each other with tensile force commensurate to the positional sllipage of a center line between a conveying passage and the paper, at both of the paper conveying passage. CONSTITUTION:When paper 32, producing a positional slip to a center line B, is conveyed to a controller 10, both sides of it is held between a drive roller 14 and an adler roller 16, and since contact area between these rollers 16 and 14 becomes smaller according to a positional slippage T, thrust force F1 of the roller 16 becomes small whereby maintenance of the state comes to be difficult, therefore the roller 16 is pushed back to the side of a small diametral part 14b by dont of resilient force F2 of a resilient member 26 stronger than the thrust force F1. And, the contact area between these rollers increases again and the thrust force F1 also increases so that the roller 16 comes to a stop at a position commensurable with the F1 and the F2. Therefore, the paper 32, being conveyed by the drive roller 14, is corrected in its attitude as a center line D approximates to the center line B of a conveying passage 12 so that it is stably conveyable irrespective of its size and characteristic, thus a paper jam or the like is preventable from occurring.</p> |
