  • Publication number: 20200071105
    Abstract: A sheet conveying device includes a correcting unit. The correcting unit corrects displacement of a sheet conveyed from an upstream side conveying path, and conveys the sheet to a downstream side conveying path. The correcting unit includes a first conveying part conveying the sheet, a first moving part moving a first frame supporting the first conveying part and a detecting part detecting a side end edge of the sheet at a reference position without displacement. The first conveying part stops conveyance of the sheet when a leading end of the sheet reaches the detecting part. While the driving of the first conveying part is stopped, the first moving part moves the first frame to move the sheet, and stops movement of the first frame, when detection result of the detecting part is changed, to position the side end edge to the reference position to correct displacement of the sheet.
