  • Patent number: 11591175
    Abstract: In a case where feeding of a subsequent sheet by a feed roller is started after the trailing edge of a preceding sheet is detected by a post-registration sensor, a control unit of a sheet feeder controls the feed roller to rotate at a first feeding speed, and in a case where the leading edge of the subsequent sheet has passed through a nip position between the feed roller and a separation roller, the control unit controls the feed roller to rotate at a second feeding speed.

  • Patent number: 10815091
    Abstract: An apparatus includes a housing provided with a conveyance path, a conveyance unit which conveys a sheet along the conveyance path, a discharge port from which the sheet conveyed along the conveyance path is discharged, a discharge tray on which the sheet discharged from the discharge port is stacked, and an attitude change unit which changes an attitude of the discharge tray. The discharge tray includes a first sheet receiving surface which is a portion facing the discharge port in a discharge direction of the sheet and on which a leading edge of the sheet lands, and a second sheet receiving surface which is formed at a predetermined inclination with respect to the first sheet receiving surface. The attitude change unit changes the attitude of the discharge tray so that the first sheet receiving surface of the discharge tray is inclined toward the discharge port.
