Apparatus for and method of preventing paper double feeding in printer |
摘要 |
An apparatus for and method of preventing paper double feeding in a paper feeding unit of a printer include a stripper which is installed to be inclined at a predetermined angle and attached to at least one front side of a plurality of paper guides, a lever which is installed at a rear side of the stripper and has a contact surface with paper transferred by a pickup roller, and a lever shaking unit which shakes the lever so that the contact surface intermittently contacts a back side of the paper transferred by the pickup roller. The method includes applying a first paper feeding resistance force to a first sheet of paper which is picked-up by the pickup roller and transferred into the printer, and intermittently applying a second paper feeding resistance to a rear side of a second sheet of paper.
