  • Publication number: 20080157459
    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portion without causing the document to come into contact with a feeding roller, a recording-sheet separation position withdrawn for separating one sheet from the other recording sheets and feeding the separated sheet, a document separation position for guiding the document to the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.

  • Patent number: 5938188
    Abstract: A sheet feeding apparatus has a sheet container which contains sheets and is removably mounted to a main body of the sheet feeding apparatus, a separation device including a conveyer and a separation member are urged against the conveyer with a predetermined separating pressure to separate the sheets fed out from the sheet container one by one, and a pressure increasing unit for increasing contact pressure between the conveyer and the separation device above the predetermined separating pressure. The pressure increasing unit increases the contact pressure until the mounting of the sheet container to the body of the sheet feeding apparatus is completed so that, even if the sheet container is inserted into the sheet feeding apparatus vigorously, the sheets are prevented from entering between the conveyer and the separation member, thus preventing poor sheet separation.
