Abstract
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.
