Abstract
A sheet stacking apparatus includes a stacking portion, a conveyance member, an abutment portion, a belt member having elasticity and configured to move the sheet toward the abutment portion, a driving source, and a controller configured to control the driving source such that (i) the belt member rotates at a first speed after the belt member contacts the current sheet and before the leading edge of the current sheet abuts against the abutment portion, and (ii) a rotational speed of the belt member is set at a second speed slower than the first speed in at least a part of a period of time after the leading edge of the current sheet abuts against the abutment portion and before the belt member contacts the next sheet.
Claims14
A sheet stacking apparatus comprising:
- a stacking portion on which a sheet is stacked;
- a conveyance member configured to convey the sheet toward the stacking portion;
- an abutment portion against which a leading edge of the sheet in a sheet conveyance direction is abutted;
- a belt member having elasticity and configured to move the sheet conveyed to the stacking portion, toward the abutment portion in the sheet conveyance direction;
- a driving source configured to drive and rotate the belt member;
- and
- a controller configured to control the driving source such that, in a case where the belt member moves a current sheet and then moves a next sheet to be stacked on the stacking portion after the current sheet is stacked on the stacking portion, (i) the belt member rotates at a first speed after the belt member contacts the current sheet and before the leading edge of the current sheet abuts against the abutment portion, and (ii) a rotational speed of the belt member is set at a second speed slower than the first speed in at least a part of a period of time after the leading edge of the current sheet abuts against the abutment portion and before the belt member contacts the next sheet.
