Problems solved by technology

Therefore, in the case of erasing a paper whose background color is other than white with a decolorizing device, there is a disadvantage (problem): although the decolorizing toner is sufficiently erased, the background color is still detected, and it is misjudged that the decolorization is not completed. Completed, the paper that could have been reused is not discharged to the reuse tray, or the result of this decolorization is recorded and saved as storage or historical data

[0032] figure 1 It is the structural diagram of the decolorizing device. The decolorizing device 100 of the first embodiment can decolorize images of paper (recording media) on which various images (printed information) have been formed, and realize reuse of paper. The color erasing device 100 has a paper feeding section 10, a first transport path 11, a second transport path 12, a first reading section 13A, a second reading section 13B, a color erasing section 15, transport rollers 16, and a path changing section (switching). Section) 17, the first paper discharge section 19, and the second paper discharge section 20.

[0033] In order to decolorize the image of the paper P to be reused, the paper feeding unit 10 feeds the paper into the decolorizing device 100 . The paper feeding unit 10 has a paper feeding tray 22 and a pickup roller 18 . Paper P is loaded on the paper feed tray 22 . The pickup roller 18 takes out the paper P one by one from the paper feed tray 10 and se...

[0068] Hereinafter, a second embodiment will be described. The description of the same parts as those in the above-mentioned first embodiment will be appropriately omitted.

[0069] In the second embodiment, the user designates the background color of the paper to be used by the decolorizing device before decolorizing. Other major structures such as figure 1 and figure 2 As explained, the difference will be described below.

[0070] In the second embodiment, in order to judge whether the paper P is usable or not, the reading of the paper surface before the decolorization process is exclusively performed, and therefore, the processing of extracting blank areas and specifying the background color as in the first embodiment is not performed.

[0071] Figure 5 The screen displayed for selecting the setting mode of the background color information is shown. This screen is displayed on the display unit 211 of the decolorization process before execution of the decolorization p...

[0086] Hereinafter, a third embodiment will be described. Description of the same parts as those in the first embodiment described above will be appropriately omitted.

[0087] Figure 8 It is a system configuration diagram of the third embodiment. As a system configuration, the decolorizing system includes, for example, a decolorizing device 100 , a client PC (Personal Computer: personal computer) 101 , and a printer 102 as a printing device for printing background color identification information. In addition, the various components of the system are interconnected via the network 103 .

[0088] In the third embodiment, the decolorizing device 100 decolorizes the image of the paper (recording medium) on which the ground color identification information and various images are formed, so as to realize the reuse of the paper. Other major structures such as in figure 1 and figure 2 As explained in , the differences are explained below.

[0089] The client PC 101 communica...

Abstract

The invention relates to a decoloring device, a reuse management method for a recording medium, and an image forming device. The occurrence of erroneous detection is suppressed in the case of decoloring a recording medium whose ground color is other than white. The decoloring device of the embodiment includes: a reading part for reading an image on a recording medium; a decoloring part for decoloring an image on the recording medium; a conveyance part for conveying the recording medium from the reading part to the decoloring part, and for conveying the recording medium to the recording part again; a ground color information acquisition part for acquiring the ground color information of the recording medium prior to decoloring by the decoloring part; and a control part for comparing the ground color of the recording medium prior to decoloring acquired by the ground color information acquisition part with the image posterior to decoloring read by the reading part, and for executing processing based on the result of comparison.

Description

technical field [0001] The embodiments described in this specification relate to the reuse management control technology of the recording medium in the decolorization device, and particularly relate to the reuse management control technology when decoloring the printed image of the recording medium other than white. Background technique [0002] Conventionally, a recording medium (paper) on which an image is formed using a decolorizing toner is erased by a decolorizing device for reuse. The decolorizing device conveys the paper to the decolorizing section and executes the decolorizing process of the toner, then judges whether the decolorization is completed, and discharges the paper decolorized to the specified standard to the reuse tray, thereby maintaining and managing the quality of the recording medium. In the decolorizing device, it is judged whether or not the decolorization is complete by reading the image of the paper again with a scanner after the decolorizing opera...
