Image erasing apparatus and image erasing method
An image erasing apparatus according to an embodiment includes a sheet supply portion that supplies a sheet and an ejector. A first conveying path conveys the sheet from the sheet supply portion toward the ejector. A reader arranged on the first conveying path reads an image on the sheet. A second conveying path branches from the first conveying path at a downstream of the reader on the first conveying path and merges with the first conveying path at an upstream of the reader on the first conveying path. An erasing unit is arranged on the second conveying path. A conveying path changing portion is arranged at a branching portion. An operating portion receives a setup of the processing to the sheet. A controller changes a conveying path of the sheet in accordance with the setup received by the operating portion before the sheet is supplied from the sheet supply portion.
1. An image erasing apparatus, comprising:
a sheet supply portion configured to supply a sheet;
conveying rollers configured to convey the sheet;
an ejector to which the sheet is ejected;
a first conveying path configured to convey the sheet from the sheet supply portion toward the ejector;
a reader arranged on the first conveying path configured to read an image on the sheet;
a second conveying path that branches from the first conveying path downstream of the reader, and that merges with the first conveying path upstream of the reader;
a decoloring unit arranged on the second conveying path and configured to decolor the image on the sheet;
a conveying path changing portion arranged at a branching portion at which the second conveying path branches from the first conveying path;
an operating portion that receives a setting of a process to be performed the sheet; and
a controller that:
controls the conveying path changing portion to change a conveyance path of the sheet in accordance with the setting received by the operating portion before the sheet is supplied from the sheet supply portion, and
controls the conveying path changing portion and the conveying rollers to convey the sheet in an order of first to the reader and subsequently to the ejector if the operating portion receives the setting of the process to be performed which does not include decoloring the image on the sheet by the decoloring unit.
2. The apparatus of claim 1 , wherein the processing which does not include decoloring the image on the sheet by the decoloring unit is a reading processing which reads the image on the sheet by the reader.
3. The apparatus of claim 1 , wherein the processing which does not include decoloring the image on the sheet by the decoloring unit is a sort processing to sort the sheet when the controller determines the sheet is reusable or not.
4. A control method of an image erasing apparatus including a sheet supply portion configured to supply a sheet, an ejector to which the sheet is ejected, a first conveying path configured to convey the sheet from the sheet supply portion toward the ejector, a reader arranged on the first conveying path configured to read an image on the sheet, a second conveying path that branches from the first conveying path downstream of the reader and that merges with the first conveying path upstream of the reader, a decoloring unit arranged on the second conveying path configured to decolor the image on the sheet, a conveying path changing portion arranged at a branching portion in which the second conveying path branches from the first conveying path, and an operating portion that receives a setting of the processing to the sheet, the method comprising:
receiving, with the operating portion, a setting of the processing performed to the sheet before the sheet is supplied from the sheet supply portion;
supplying the sheet from the sheet supply portion;
conveying the sheet from the sheet supply portion to the reader;
conveying the sheet after passing the reader to the ejector or the second conveying path based on the received setup, wherein the sheet is conveyed in order of the reader and the ejector if the operating portion receives the setting of the processing does not include decoloring the image on the sheet by the decoloring unit.
5. The method of claim 4 , wherein the processing which does not include decoloring the image on the sheet by the decoloring unit is a reading processing which reads the image on the sheet by the reader.
6. The method of claim 4 , wherein the processing which does not perform by the erasing unit is a sort processing to sort the sheet when the controller determines the sheet is reusable or not.
