Patent ID: 7637497

Claim:
A document feeding device for feeding documents, comprising: a document input tray on which documents to be fed are placed; a document output tray to which the documents are ejected; a feeding mechanism which is provided for a feeding path connecting the document input tray and the document output tray via a scanning position and feeds each document from the document input tray to the scanning position and from the scanning position to the document output tray; a turnover mechanism which is provided for a turnover path connected to the feeding path and returns the document after passing through the scanning position to a position on the upstream side of the scanning position while interchanging the front end and the rear end of the document in a feeding direction; a pair of ejection rollers which ejects each document to the document output tray; an ejection mechanism which switches between a first ejection mode for successively ejecting each document while stacking the ejected document on documents previously ejected to the document output tray and a second ejection mode for successively ejecting each document while sliding the ejected document under the documents previously ejected to the document output tray by relatively moving a nipping position of the pair of ejection rollers and an upstream end, in a feeding direction, of the document output tray in a vertical direction; a pressing member which is configured to pivot up and down on the downstream side of the pair of ejection rollers in the feeding direction and which presses down the ejected documents on the document output tray from above in the first ejection mode; and a retracting mechanism which retracts the pressing member by pivoting the pressing member upward in the second ejection mode.
