Abstract
A sheet stacking device includes a base member and a sheet stacking portion on which a sheet is stacked. The sheet stacking portion is supported by the base member swingably in a first direction orthogonal to a second direction, and swings and changes an inclination angle for holding the stacked sheet.
Claims7
A sheet feeding device comprising:
- a body;
- a storage portion configured to be drawn out from the body;
- a supporting portion provided on the storage portion and configured to support sheets;
- a feed portion configure to feed a sheet supported by the supporting portion;
- a driving mechanism which is able to lift the supporting portion such that an uppermost sheet of the sheets supported on the supporting portion is kept at a position where the uppermost sheet can be fed by the feed portion;
- a sheet stacking portion, provided on the supporting portion, on which a sheet is stacked, the sheet stacking portion being swingable in a width direction orthogonal to a sheet feeding direction in which the feed portion feeds the sheet;
- and
- a pair of widthwise restricting portions restricting both ends, in a width direction, of the sheets stacked on the sheet stacking portion on the supporting portion,
- wherein the sheet stacking portion on the supporting portion is swingable in the width direction while the supporting portion is lifted by the driving mechanism, and an uppermost surface of the sheets stacked on the sheet stacking portion is changed from an inclined state to a substantially horizontal state according to a lifting of the sheet stacking portion.

A sheet feeding device comprising:
- a body:
- an envelope stacking portion configured to stack the plurality of enevelopes;
- a supporting portion configured to support the envelope stacking portion;
- a feed portion configured to feed an envelope stacked on the envelope stacking portion;
- a driving mechanism which is able to lift the supporting portion such that an uppermost envelope stacked on the envelope stacking portion is kept at a feed position where the uppermost envelope can be fed by the feed portion;
- a storage portion on which the supporting portion is provided, and that can be drawn out from the body;
- and
- a pair of widthwise restricting portions restricting both ends, in the width direction, of the envelopes stacked on the envelope stacking portion on the supporting portion,
- wherein the envelope stacking portion is swingable in a width direction orthogonal to a feeding direction in which the feed portion feeds the envelope, while the supporting portion is lifted by the driving mechanism,
- and an uppermost surface of the envelopes stacked on the envelope stacking portion is changed from an inclined state to a substantially horizontal state according to a lifting of the supporting portion.
