  • Patent number: 9126793
    Abstract: A sheet feed device has a tray with holding surface for holding sheets, a feed unit for feeding sheets from the tray, and a separation plate. The separation plate has an inclined surface and two or more separation portions that separate a sheet from the sheets held in the tray. At least one of the separation portions projects a first distance from the inclined surface. The separation plate also has a projection positioned on the inclined surface that projects a second distance from the inclined surface. The second distance is greater than the first distance. A first of the separation portions is positioned upstream of the particular projection in the sheet feed direction, and a second of the separation portions positioned downstream of the particular projection in the sheet feed direction.
