Abstract

A document administration system includes an administration unit, a discrimination information image discriminating unit, and an image forming apparatus which, forms an image on a recording medium in case that the discrimination information image discriminating unit discriminates that the recording medium has the discrimination information image before the image is formed on the recording medium, and forms the image and the discrimination information image based on the discrimination information connected to the image on the recording medium in case that the discrimination information image discriminating unit discriminates that the recording medium does not have the discrimination information image before the image is formed on the recording medium.

First claim

What is claimed is:

1. A document administration system, comprising:
an image forming device to form an image on a recording medium;
an administration apparatus configured to administer administration information of the image formed on the recording medium in connection with discrimination information of the recording medium, the administration information including security information representing a security level; and
a decoloring apparatus configured to decolor a decoloring image formed on the recording medium, the decoloring apparatus including:
a reading device to read the discrimination information image based on the discrimination information formed on the recording medium;
a display unit to receive a decolor entry of the decoloring image and display a decolor entry image plane;
a decoloring device to decolor the decoloring image formed with erasable coloring agent on the recording medium and displayed on the display unit as a function of the security level and based on a reading result of the reading device, the reading result including the security information;
a first eject tray to recover the recording medium which is reusable after the decoloring image has been decolored by the decoloring device;
a second eject tray to recover the recording medium which is not reusable and is normally to be disposed for recycling processing; and
a third eject tray differing from the first and second eject trays to recover and perform a security disposition on the recording medium with a high security level recognized from the discrimination information image read by the reading device.

2. The system of claim 1 , wherein the administration apparatus includes an information memory device to store the administration information in connection with the discrimination information, and updates the information memory device each time the decoloring device in the decoloring apparatus decolors the image.

3. The system of claim 1 , further comprising:
a non-decoloring image forming device to form the image with unerasable coloring agent, and forms the discrimination information image on the recording medium by the non-decoloring image forming device.

4. The system of claim 1 , wherein the third eject tray keeps the security by a key.

5. The system of claim 1 , wherein the third eject tray keeps a security key by a password.

6. A decoloring apparatus comprising:
an image forming device to form an image on a recording medium;
a reading device to read a discrimination information image based on the discrimination information formed on the recording medium, the discrimination information being connected with the administration information of the image formed on the recording medium, the administration information being interested by an administration device and including a security information representing a security level;
a decoloring device to decolor a decoloring image formed with erasable coloring agent on the recording medium as a function of the security level and based on a reading result of the reading device, the reading result including the security information, the decoloring device including a display unit to receive a decolor entry of the decoloring image and display a decolor entry image plane, wherein the decoloring device decolors the decoloring image displayed on the display unit; and
a first eject tray to recover the recording medium which is reusable after the decoloring image has been decolored by the decoloring device;
a second eject tray to recover the recording medium which is not reusable and is normally to be disposed for recycling processing; and
a third eject tray differing from the first and second eject trays to recover and perform a security disposition on the recording medium with a high security level recognized from the discrimination information image read by the reading device.

7. The device of claim 6 ,
wherein the third eject tray includes a security box, the recording medium being conveyed to the security box to perform the security disposition on the recording medium.

8. The device of claim 7 , wherein the security box keeps the security by a key.

9. The device of claim 7 , wherein the security box keeps the security by a password.

10. A document administration method in a document administration system including an administration apparatus and a decoloring apparatus, comprising:
forming an image on a recording medium;
administering, in the administration apparatus, administration information of the image formed on the recording medium in connection with discrimination information of the recording medium, the administration information including security information representing a security level;
reading, in the decoloring apparatus, the discrimination information image based on the discrimination information formed on the recording medium;
receiving a decolor entry of a decoloring image and displaying a decolor entry image plane;
decoloring, in the decoloring apparatus, the decoloring image formed with erasable coloring agent on the recording medium and displayed in the displaying step as a function of the security level and based on the reading the discrimination information image based on a reading result of the reading step, the reading result including the security information; and
recovering the recording medium which is reusable after the decoloring image has been decolored by the decoloring device in a first eject tray;
recovering the recording medium which is not reusable and is normally to be disposed for recycling processing in a second eject tray; and
recovering and performing a security disposition on the recording medium with a high security level recognized from the discrimination information image read in a third eject tray differing from the first and second eject trays.

11. The method of claim 10 , further comprising:
storing the administration information in connection with the discrimination information in an information memory device.

12. The method of claim 11 , further comprising:
updating the information memory device each time the decoloring the decoloring image formed on the recording medium.
