Patent ID: 7637501

Claim:
A document feeding device for conveying a document onto a reading position, comprising: a sheet feeding tray; an upstream guide member extending from the sheet feeding tray for guiding the document from the sheet feeding tray, said upstream guide member forming an upstream path of a document conveying path; a downstream guide member extending from the upstream guide member for guiding the document from the upstream guide member onto the reading position; an opposite guide member located opposite the downstream guide member, said opposite guide member forming a downstream part of the document conveying path; a support member pivotally supporting the upstream guide member so that the upstream guide member is movable in a direction to open the document conveying path; and a guide moving device for slidably moving the downstream guide member away from the opposite guide member upon a pivoting opening operation of the upstream guide member, wherein the downstream guide member includes one end portion, and the guide moving device slidably moves the one end portion so that a guide surface of the downstream guide member is separated from the opposite guide member, and wherein the guide moving device comprises a lever member pivotally supported by a shaft and having an engaging portion engageable with a part of the upstream guide portion during opening of the upstream guide member and a rotating support portion pivotally supporting the other end portion of the downstream guide member.
