PURPOSE:To provide a sheet conveyor system that is able to perform any skew compensation of the sheet simply and accurately. CONSTITUTION:Axial length in a center roller (sub roller) 30 is made shorter enough than that of a main roller 28, and this center roller 30 is paralleled with the main roller 28 and opposed almost to a central part in the axial direction of this main roller 28, while it is set up in a state of being added with nip pressure. Accordingly, in a film (sheet) 20, tension by means of tensile force of the center roller 30 is imparted to a central part of this film 20, whereby each feed rate in both right and left parts is varied to sane extent, so that the film 20 is displaced so as to become a vertical direction to the axial direction of the main roller 28 with the center roller 30 as the center. |
