Abstract:
1. A document feeding device for feeding documents, comprising: a document input tray on which documents to be fed are configured to be placed; a document output tray to which the documents are configured to be 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 an upstream side of the scanning position while interchanging a front end and a rear end of the document in a feeding direction; and an ejection mechanism which is configured so that its document ejection mode can be switched between a first ejection mode for successively ejecting each document while stacking each document on documents already ejected to the document output tray and a second ejection mode for successively ejecting each document while sliding each document under the documents already ejected to the document output tray, wherein the document output tray includes a tray part and a flap part which is attached to the tray part to be pivotable, situated on an upstream side of the tray part in the feeding direction, and equipped with a projecting part, wherein a switching drive mechanism pivots the flap part in a vertical direction, wherein the flap part includes a first flap which is attached to the tray part to be pivotable on the upstream side of the tray part in the feeding direction and a second flap which is attached to the first flap to be pivotable on the upstream side of the first flap in the feeding direction and is equipped with a bent part, wherein, when the flap part pivots upward in the second ejection mode, the bent part of the second flap forms the projecting part, and wherein, when the flap part pivots downward in the first ejection mode, the bent part relatively sinks with respect to the second flap compared to its relative position in the second ejection mode due to pivoting of the second flap with respect to the first flap.
