Patent number: 5612766Abstract: A device for regenerating a sheet-like recoding medium which feeds a printed sheet-like recording medium. A regenerating treatment unit eliminates a image formed on the recording medium. The recording medium is then discriminated and separated based on whether the regenerated recording medium is reusable or not and whether the regenerated recording medium is to be treated again by the regenerating treatment unit, and a storing unit stores the separated reusable recording medium. Further, a control section controls the regenerating treatment unit to treat the regenerated recording medium again when the regenerated recording medium is judged to be treated again by the regenerating treatment unit.Type: GrantFiled: April 14, 1995Date of Patent: March 18, 1997Assignee: Ricoh Company, Ltd.Inventors: Toru Iida, Michihito Ohashi, Yoshihiro Sakai, Shin-ichi Kuramoto, Shunichi Chiba, Yasuo Asahina, Junko Tomita
