Abstract
An erasing apparatus includes a sheet feeding unit from which a sheet is fed into the erasing apparatus, an erasing unit configured to perform an erasing processing on both surfaces of the sheet, a scanning unit configured to scan and generate image data of a bottom surface and a top surface of the sheet, a first storing unit, a second storing unit, and a controller. The controller is configured to determine, based on the image data, whether the bottom surface of the sheet is reusable and whether the top surface of the sheet is reusable. Further, the controller is configured to cause, if both the bottom and top surfaces have been subject to the erasing processing and are determined to be reusable, the sheet to be conveyed to one of the first and second storing units based on a both-sides-erased criteria.
Claims14
An erasing apparatus, comprising:
- an erasing unit configured to perform an erasing process with respect to a plurality of sheets, each having images on both surfaces;
- a sheet scanner configured to scan both surfaces of each of the sheets and generate image data of each surface of said each sheet, before and after the erasing process;
- a sheet storage unit;
- and
- a controller configured to:
- determine, based on the image data, whether or not each surface of each of the sheets has become reusable as a result of the erasing process, and
- with respect to sheets of which only one surface is determined to be reusable, cause the reusable surfaces to face the same side in the sheet storage unit.
A method for processing a plurality of sheets, each having images on both surfaces, the method comprising:
- scanning both surfaces of each of the sheets and generating image data of each surface of said each sheet;
- after the scanning, performing an erasing process with respect to the sheets;
- after the erasing process, scanning both surface of each of the sheets and generating image data of each surface of said each sheet;
- determining, based on the image data before and after the erasing process, whether or not each surface of each of the sheets has become reusable as a result of the erasing process;
- and
- with respect to sheets of which only one surface is determined to be reusable, placing said sheets in sheet storage, such that the reusable surfaces face the same side therein.
