Abstract
A sheet feeder includes a separation roller having a circumferential surface that contacts a first sheet to be fed first among stacked sheets and picks up the first sheet and one or more second sheets adjacent to the first sheet, a separation arm that is closer to the circumferential surface of the separation roller downstream in a feeding direction and configured to apply higher frictional resistance to the second sheets than the first sheet to feed the first sheet ahead of the second sheets, and a guide member including a guide portion that has a lower-friction surface than the separation arm and extends from the separation arm with a distal end thereof in contact with or close to the circumferential surface of the separation roller. The guide portion guides the first and second sheets along the circumferential surface of the separation roller.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
