Abstract:
1. A decoloring apparatus comprising: a first sheet conveying path for guiding a sheet, which is fed from a feeding port, to a discharge port; a second sheet conveying path that branches from the first sheet conveying path, for guiding the sheet conveyed through the first sheet conveying path to another conveyance destination; a decoloring processing section configured to decolor an image formed with a decolorable colorant on the sheet at a location between the feeding port and a branching point where the second sheet conveying path branches from the first sheet conveying path; a first flapper configured to switch a destination of the sheet conveyed through the first sheet conveying path to be the discharge port in the first sheet conveying path or the second sheet conveying path; an image reading section located between the decoloring processing section and the branching point and configured to read the image on the sheet decolored by the decoloring processing section; a sensor located between the feeding port and the decoloring processing section and configured to detect a leading end and a trailing end of the sheet conveyed through the first sheet conveying path; and a path control section configured to control the first flapper so that the destination of the sheet through the first sheet conveying path is the discharge port when the sensor does not detect the trailing end of the sheet within a time from when the sensor detects the leading end of the sheet to when the leading end of the sheet arrives at the branching point.
