When a conveying force is increased in order to switch back a sheet only by a pair of paper discharge rollers, when the conveying force of the conveying belt is small, each feed after the sheet is nipped between the pair of paper discharge rollers (in this case, The paper is pulled intermittently by the pair of paper discharge rollers and the conveyance unit (conveyance belt)), so the feeding accuracy deteriorates and noise is generated due to the tension generated when the paper is pulled To solve the problems. The drive start timing of the paper discharge roller pair 12 when the paper P is being conveyed intermittently by the transport belt 7 and the paper discharge roller pair 12 is delayed from the drive start timing of the transport belt 7. A time lag Tα is provided between the drive start timings. [Selection] Figure 2 |
