Abstract
The invention provides a thin sheet conveying device, which is driven by a single driving unit and meanwhile achieves thin sheet inclination prevention and subsequent second thin sheet conveying before a first thin sheet is discharged in a condition when a thin sheet is conveyed in a way to have the two faces read. If paper conveyed on a normal conveying path (130) reaches a paper discharging roller (125) position, then a control part makes the driving unit rotate in a reverse direction. Consequently, the paper discharging roller (125) rotates in a reverse way and makes the paper conveyed on a coordinated conveying path (131). If the paper reaches a drawing-out conveying roller (114) position, then the control part makes driving force transferred to the drawing-out conveying roller (114). Meanwhile, the driving unit is made to rotate in a forward direction. If the rear end of the paper passes through the drawing-out conveying roller (114) position, then the control part stops the driving force transfer towards the drawing-out conveying roller (114) and further transfers the driving force to a feeding roller (113).
