置を提供することにある。However, in recent years, there has been an increasing movement to promote the reuse of used paper due to environmental problems, resource problems, etc., and attention has been paid to the use of recycled paper. In the shredded waste paper, there is a problem that the fibers are fined by cutting the paper fibers, and the production yield of waste pulp from these shredded waste papers is reduced. Further, since the cutting direction of a waste document shredded in a dry state is constant, it is relatively easy to restore a state in which a shredded paper piece, particularly a strip-shaped shredded paper piece, to a state before shredding, and the waste document Was also an inevitable problem. Also, since the shredded paper pieces cut into such a band shape are bulkier and bulkier than the state of the documents before shredding, the storage of the shredded paper waste is much more than before shredding. There is also a problem that a large space is required and that it takes time to carry out processing such as transportation of the shredded paper pieces. In order to reduce this "bulk", there is also a method in which waste paper is shredded with both a roll cutter and a spiral cutter and the shredded paper pieces are made into a fine rectangular shape. Further, there is a problem that the production yield of waste paper pulp from shredded waste paper is further reduced. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a novel document processing apparatus which improves the above-mentioned disadvantages of the prior art.

That is, the present invention relates to a document processing apparatus which performs a disposal process of a document by a wet method, wherein a rotary conveyor part of which is disposed in a water tank, and which is located above the rotary conveyor part and communicates with the rotary conveyor part. And that only the water in the waste treated paper including the water conveyed by the rotary conveyor from the inside of the water tank is discharged into the water tank by the treated paper storage section. This is a document processing apparatus characterized by the following.

理も容易となる。According to the document processing apparatus of the present invention, it is possible to easily dispose of a document by a wet method without extremely reducing the size of the paper fiber, thereby increasing the production yield of waste paper pulp from the discarded document. I can do it. In addition, since the document is swollen in water, the risk of secret leakage from the discarded document is reduced. Further, the space for storing the waste after the disposal can be reduced, and the processing such as transportation of the waste can be facilitated.
