Abstract
A sheet feeding device includes a guiding member having an upper guiding surface for guiding the upper surface of a document and a lower guiding surface for guiding the lower surface of the document to guide the document to a support portion. The guiding member is movable to a set position for guiding the document to the support portion without causing the document to come into contact with a feeding roller, a recording-sheet separation position withdrawn for separating one sheet from the other recording sheets and feeding the separated sheet, a document separation position for guiding the document to the feeding roller, and a sheet return position for returning the recording sheet or the document to a corresponding support portion using a return lever. The guiding member is held via a spring such that the guiding member can be returned by itself from the sheet return position to the set position.
