In some cases, it was unavoidable that there was a need to view the document after cutting it.

On the other hand, if it is thought that it may be necessary to browse the document later, it cannot be decided to destroy the confidential document unless it turns out to be completely unnecessary, and the number of confidential documents continues to increase. There is also an inconvenience that it becomes difficult to secure the storage space.

As disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 2-72384, even if the configuration in which the shredder mechanism is mounted on the OA equipment is adopted, the miscopy and the abnormal termination which are clearly determined to be unnecessary are made. It merely shreds printed materials and the like to achieve confidentiality protection, and does not provide a solution to the proposition of how to handle normally created documents.

Furthermore, even if a confidential document is judged to be unnecessary because the original purpose was achieved, it is guaranteed that there is a large amount of important information and the confidential information will not be leaked if the individual contents described in the document itself are examined. If so, it can be said to be a treasure trove of information that should be stored and freely browsed as needed.

Therefore, although the number of prepared documents is increasing due to the development of OA equipment, even the confidential documents which are considered to be almost unnecessary, the fact that the disposal cannot be easily judged has not been improved. . for that reason,
It has been desired to realize confidential document management that ensures efficient use of office space while maintaining confidentiality of confidential documents.
