Title: Document reader
Inventor: YOSHIMIZU HIDEKI
IPC: H04N1/31
Filed: 2000-08-17
Abstract: PROBLEM TO BE SOLVED: To stably feed a document passed through a separative paper feed part in a reading part, and allows the document to be driven by a drive motor in a document reading portion. SOLUTION: A feed roller for load removal 11 is installed in a document feed route 10 between a separative paper feed part 3 and a feed roller for reading 7. The linear speeds of the feed roller for reading 7 and the feed roller for load removal 11 are differentiated to absorb a feed load on the document applied at the separative paper feed part 3 by the feed roller for load removal 11. Thus, an acting force such as a tension is prevented from being transmitted directly from the separative paper feed part 3 to the feed roller for reading 7.
