Abstract
A sheet feeding apparatus includes a stacking portion, a feed member provided above the stacking portion and configured to feed an uppermost sheet among the sheets stacked on the stacking portion, and a trailing-end regulating member movable in the sheet feeding direction and configured to regulate a position of a trailing end of the sheets stacked on the stacking portion in the sheet feeding direction. The trailing-end regulating member includes a support portion configured to support a lower surface of the sheets stacked on the stacking portion. The support portion has a projecting shape in which a center portion of the support portion in a sheet width direction projects upward as compared with end portions of the support portion in the sheet width direction.

A sheet feeding apparatus comprising:
- a stacking portion on which sheets are stacked;
- a feed member provided above the stacking portion and configured to feed an uppermost sheet among the sheets stacked on the stacking portion toward a sheet feeding direction;
- and
- a trailing-end regulating member movable in the sheet feeding direction and configured to regulate a position of a trailing end of the sheets stacked on the stacking portion in the sheet feeding direction,
- wherein the trailing-end regulating member includes a support portion configured to support a lower surface of the sheets stacked on the stacking portion,
- wherein the support portion has a projecting shape in which a center portion of the support portion, in a sheet width direction, projects upward as compared with end portions of the support portion in the sheet width direction, the sheet width direction being a direction perpendicular to both the sheet feeding direction and an up-down direction,
- wherein the trailing-end regulating member further includes a body portion to which the support portion is detachably attached, and
- wherein the body portion from which the support portion is detached is capable of regulating the position of the trailing end of the sheets on the stacking portion.
A sheet feeding apparatus comprising:
- a stacking portion on which sheets are stacked;
- a feed member provided above the stacking portion and configured to feed an uppermost sheet among the sheets stacked on the stacking portion toward a sheet feeding direction;
- and
- a trailing-end regulating member movable in the sheet feeding direction and configured to regulate a position of a trailing end of the sheets stacked on the stacking portion in the sheet feeding direction, wherein:
- the trailing-end regulating member includes a first support portion configured to support a lower surface of the sheets stacked on the first stacking portion, and
- the first support portion has a projecting shape in which a center portion of the support portion, in a sheet width direction, projects upward as compared with end portions of the first support portion in the sheet width direction, the sheet width direction being a direction perpendicular to both the sheet feeding direction and an up-down direction;
- a second support portion provided downstream of the first support portion in the sheet feeding direction and configured to support the lower surface of the sheets stacked on the stacking portion, wherein:
- the second support portion has a projecting shape in which a center portion of the second support portion, in the sheet width direction, projects upward as compared with end portions of the second support portion in the sheet width direction;
- and
- a friction portion provided at a downstream end of the second support portion in the sheet feeding direction, the friction portion being configured to come into contact with the lower surface of the sheets on the stacking portion and reduce displacement of the sheets on the stacking portion caused by force received from the feed member.
