1. An image reading apparatus comprising:
a stacking portion on which a sheet is to be stacked;
a feeding unit configured to feed the sheet stacked on the stacking portion in a feeding direction;
a reading unit configured to read an image on the sheet fed by the feeding unit; and
a discharge portion provided below the stacking portion and configured to discharge the sheet having the image read by the reading unit,
wherein the stacking portion includes:
a first support surface configured to support the sheet,
a second support surface configured to move, in a widthwise direction perpendicular to the feeding direction, between a first position where the second support surface supports the sheet together with the first support surface and a second position where the second support surface retracts from the first position, wherein the second support surface is positioned under the first support surface when the second support surface is positioned at the second position,
a first regulating unit provided on the first support surface to be movable in the widthwise direction, having a first regulating surface with which one end of the sheet in the widthwise direction comes into contact, and configured to regulate a position of the sheet stacked on the stacking portion in the widthwise direction, and
a second regulating unit provided on the second support surface to be movable in the widthwise direction together with the second support surface, having a second regulating surface with which an other end of the sheet opposite to the one end in the widthwise direction comes into contact, and configured to regulate a position of the sheet in the widthwise direction,
wherein the first support surface includes a downstream support portion configured to support the sheet on a downstream of the second support surface in the feeding direction, and
wherein a part of the second regulating surface overlaps the downstream support portion of the first support surface as viewed in a direction perpendicular to the first support surface.
