Decoloring apparatus, controlling apparatus, method for displaying

摘要

According to one embodiment, an decoloring apparatus includes: an decoloring processing unit configured to apply decoloring processing decoloring a color of an decolorable colorant; a sheet conveying unit configured to convey the sheet and cause the sheet to pass through the decoloring processing unit; an image reading unit arranged further on an upstream side than the decoloring processing unit in a sheet conveying direction by the sheet conveying unit and configured to read the image formed on the sheet conveyed by the sheet conveying unit; a thickness sensor arranged further on the upstream side than the decoloring processing unit in the sheet conveying direction by the sheet conveying unit and configured to detect thickness of the sheet conveyed by the sheet conveying unit; an decolorability determining unit configured to determine, on the basis of a detection result in at least one of the image reading unit and the thickness sensor, executability of the decoloring processing in the decoloring processing unit of the sheet set as a detection target; a storing unit configured to store information indicating a number of sheets determined as decoloring processing unexecutable by the decolorability determining unit; and a display control unit configured to cause, when the apparatus is started, a display to screen-display the information stored in the storing unit indicating the number of sheets determined as decoloring processing unexecutable by the decolorability determining unit.

主权项

1. A decoloring apparatus comprising:
a sheet conveying unit configured to convey a sheet; a decoloring unit configured to decolor a color of an image formed with a decolorable colorant on the sheet conveyed by the sheet conveying unit; a processing unit configured to determine a number of sheets made reusable by having color thereon successfully erased in the decoloring unit, to calculate an environmental load contribution ratio calculated by multiplying the number of sheets made reusable with a specified coefficient, and to determine a number of sheets on which decoloring by the decoloring unit is impossible; and a display control unit configured to cause a display unit to display the number of sheets made reusable and the environmental load contribution ratio calculated by the processing unit, and to cause the display unit to display the number of sheets on which decoloring by the decoloring unit is determined to be impossible by the processing unit.
