Abstract
A sheet feeding apparatus includes a sheet stacking portion, a lift plate, an actuating segment, driving unit, a sheet feeding portion, a first detecting portion, a remaining amount detection portion. The remaining amount detection portion includes a detection piece, a link mechanism, a second detecting portion, a controller. The link mechanism couples together the driving shaft and the detection piece at a coupling position attained by pivoting the lift plate through a predetermined angle from a lower limit position in rotation direction, so as to let the driving shaft and the detection piece rotate together. The second detecting portion senses whether or not the detection piece is present. The controller determines the remaining quantity level of the stacked sheets according to whether or not the second detecting portion is detecting the detection piece being present.
