Abstract
According to an embodiment, an image erasing apparatus includes a reading unit, an erasing unit, an image forming unit, and a controller. The reading unit reads identification information formed on a sheet conveyed. The erasing unit erases a part or all of a first image formed on the sheet after the identification information is read. The controller obtains image data corresponding to the identification information that is read by the reading unit. The controller controls the image forming unit so as to form a second image, which is indicated by the obtained image data, onto the sheet from which the first image has been erased.
Claims10
An image erasing apparatus comprising:
- a feeding unit which supplies a sheet to a conveyance path, the sheet having formed thereon:
- in a first region, a first image having first information relating to a predetermined purpose, and
- in a second region different from the first region, identification information from which one of the sheet and a user can be identified;
- a reading unit which reads the identification information formed on the sheet conveyed on the conveyance path;
- a storage unit which stores, in advance, image data corresponding to a second image, in association with the identification information, the second image having second information relating to the predetermined purpose, the second image being different from the first image;
- an erasing unit, provided on the conveyance path at a downstream side with respect to the reading unit in a conveying direction of the sheet, which decolors a part or all of the first image formed on the sheet;
- an image forming unit, provided on the conveyance path at a downstream side with respect to the erasing unit in the conveying direction of the sheet, which forms an image onto the sheet after the erasing unit finishes decoloring the first image;
- and
- a controller which receives the identification information that is read by the reading unit, obtains from the storage unit the image data corresponding to the second image based on the received identification information, and controls the image forming unit to form the second image based on the obtained image data, onto the first region of the sheet from which the first image has been decolored.
An image erasing method comprising:
- conveying a sheet having formed thereon:
- in a first region, a first image having first information relating to a predetermined purpose, and
- in a second region different from the first region, identification information from which one of the sheet and a user can be identified;
- storing, in advance, image data corresponding to a second image, in association with the identification information, the second image having second information relating to the predetermined purpose, the second image being different from the first image;
- reading the identification information formed on the conveyed sheet;
- decoloring a part or all of a first image formed on the sheet after reading the identification information;
- receiving the identification information that has been read;
- obtaining the stored image data corresponding to the second image based on the received identification information;
- and
- forming the second image, which is based on the obtained image data, onto the first region of the sheet from which the first image has been decolored.
