ABSTRACT:
In the disposal device for paper documents according to the present invention, the feeding of paper that is to be disposed can be done either automatically with a feeding unit or manually from a manual inlet. Therefore, the disposal of sensitive paper documents can be carried out sheet by sheet by placing the paper on the automatic paper feed unit while paper documents which do not require any security measures may be manually fed into the disposal device for an immediate shredding process. Therefore, the present invention allows both appropriate and efficient disposal of paper documents without regard to whether the paper documents to be disposed require security measures or not.
