Embodiment Construction

[0020] Hereinafter, embodiments will be described with reference to the drawings.

[0021] figure 1 It is a diagram schematically showing a configuration example of an image erasing device according to an embodiment.

[0022] like figure 1 As shown, the image erasing device 10 includes a supply unit 11 , a main transport path 12 , an erasing unit 13 , a sensor 14 , a switching mechanism 15 , a reverse transport path 16 , a discharge unit 17 and a controller 18 .

[0023] The main transport path 12 is used to transport paper P to be image erased. The main transport path 12 transports the paper P from the supply unit 11 to the discharge unit 17 . For example, the main transport path 12 takes out one sheet of paper from, for example, a paper tray as the supply section 11 . The main transport path 12 transports the paper P from the supply unit 11 to the erasing unit 13 . The main transport path 12 transports the paper P passing through the erasing unit 13 to the sensor 14 . ...

Abstract

According to one embodiment, an image erasing apparatus decolors an image printed on a paper sheet using an ink containing at least a leuco dye, a developer, water, a water-soluble organic solvent, and a surfactant. The image erasing apparatus includes a heating unit, a feedback mechanism, and a control unit. The heating unit heats the paper sheet. The feedback mechanism supplies the paper sheet heated by the heating unit to the heating unit again. The control unit causes the feedback mechanism to supply the paper sheet to the heating unit a plurality of times so as to heat the paper sheet a plurality of times.

Description

[0001] Cross References to Related Applications [0002] This application is based upon and claims the benefit of priority from Japanese Patent Application No. 2010-197043 filed September 2, 2010, the entire contents of which are hereby incorporated by reference. technical field [0003] Embodiments of the present invention relate to an image erasing device and an image forming apparatus including the image erasing device. Background technique [0004] In recent years, in order to protect the global environment and suppress CO 2 As a result of the greenhouse effect, the efficient use of paper resources has become a major issue. In order to efficiently use paper resources, "reuse (リュース)" technology is adopted. As a “recycling” technique, there is a technique of printing an image on paper (image recording medium) with erasable ink, and then heating the paper to erase (decolorize) the image. The paper after the image is erased has a problem that if the image is printed again...
