Abstract:
1. An automatic sheet feeder, comprising: a sheet setting unit including a housing, 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, the sheet detector comprising a detection member, a rotary shaft about which the detection member rotates and to which the detection member is fixedly attached, and a sensor to detect the sheet set on the sheet setting unit according to a movement of the detection member; and a rotating member to cause the detection member of the sheet detector to rotate in a direction such that an angle between a line that extends 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, wherein the rotating member includes a lever that is fixedly attached to the rotary shaft and contacts the housing of the sheet setting unit, as the cover closes, to rotate in a direction such that an angle between the detection member and the surface of the sheet decreases.
