    摘要： An image scanner includes a stationary original plate on which a stationary original is placed and a moving original plate, over which a moving original is conveyed, aligned with the stationary original plate in a sub-scanning direction and tilted relative to the stationary original plate by a given angle. A reader is movable in the sub-scanning direction between a stationary original reading span disposed opposite the stationary original via the stationary original plate to read an image on the stationary original and a moving original reading position disposed opposite the moving original via the moving original plate to read an image on the moving original. The reader pressingly contacts the stationary original plate and the moving original plate as the reader moves in the sub-scanning direction.

    摘要： A sheet conveyance unit including a sheet tray on which a stack of sheets is placed, a sheet feed member to feed sheets from the stack of sheets, a separation/feed unit to separate a topmost sheet from the rest of sheets fed by the sheet feed member and feed the topmost sheet to a predetermined position, and a pre-separation unit disposed between the sheet tray and the separation/feed unit. The pre-separation unit includes a downward sloped portion to guide a leading edge of each sheet diagonally downward, and an upward sloped portion provided downstream from the downward sloped portion in a conveyance direction of the sheets to guide the leading edge of each sheet diagonally upward. Both ends of the upward sloped portion in a lateral direction are sloped upward more gently than the center of the upward sloped portion.

    摘要： An automatic sheet feeder includes a sheet setting unit to set a sheet to be fed by a sheet feeding member, an openably closable cover rotatably disposed over an upper portion of the sheet setting unit, a sheet detector rotatably supported on the cover to detect whether or not a sheet is set on the sheet setting unit and including a detection member, a rotary shaft about which the detection member rotates, and a sensor to detect the setting of the sheet according to a movement of the detection member, and a rotating member to cause the detection member to rotate in a direction such that an angle between a line extending in a longitudinal direction of the detection member and a surface of the sheet set on the sheet setting unit decreases as the cover rotates from an open position to a closed position.
