Abstract
A conveying unit receives a sheet from an upstream unit and conveys the sheet on a conveying path. A stacking unit stacks the sheet conveyed from the conveying unit. An aligning unit sets the sheet back in a direction opposite to a sheet conveying direction and aligns the sheet by bumping the sheet against a reference wall. A sheet discharging unit discharges the sheet aligned on the stacking unit. When a predetermined condition is satisfied, a control unit sets a timing for discharging the sheet by the sheet discharging unit earlier than a normal sheet discharge timing.
Claims17
A sheet aligning device comprising:
- a conveying unit that receives at least one sheet from an upstream unit and conveys the at least one sheet on a conveying path;
- a stacking unit that stacks the at least one sheet conveyed from the conveying unit;
- a first aligning unit that sets the at least one sheet back in a direction opposite to a sheet conveying direction and aligns the at least one sheet by bumping the at least one sheet against a reference wall;
- a sheet discharging unit that discharges the at least one sheet from the stacking unit in the sheet conveying direction;
- and
- a control unit that, when a predetermined condition is satisfied, sets a timing for the discharging unit to discharge the at least one sheet as the first aligning unit is setting the at least one sheet back in the direction opposite to the sheet conveying direction but prior to the first aligning unit successfully completing the bumping of the at least one sheet against the reference wall.
A sheeting processing device comprising:
- a sheet aligning device that includes
- a conveying unit that receives at least one sheet from an upstream unit and conveys the at least one sheet on a conveying path,
- a stacking unit that stacks the at least one sheet conveyed from the conveying unit,
- a first aligning unit that sets the at least one sheet back in a direction opposite to a sheet conveying direction and aligns the sheet by bumping the at least one sheet against a reference wall,
- a sheet discharging unit that discharges the at least one sheet from the stacking unit in the sheet conveying direction, and
- a control unit that, when a predetermined condition is satisfied, sets a timing for the discharging unit to discharge the at least one sheet as the first aligning unit is setting the at least one sheet back in the direction opposite to the sheet conveying direction but prior to the first aligning unit successfully completing the bumping of the at least one sheet against the reference wall.
An image forming apparatus comprising:
- a sheeting processing device that includes a sheet aligning unit, the sheet aligning unit including
- a conveying unit that receives at least one sheet from an upstream unit and conveys the at least one sheet on a conveying path,
- a stacking unit that stacks the at least one sheet conveyed from the conveying unit,
- a first aligning unit that sets the at least one sheet back in a direction opposite to a sheet conveying direction and aligns the at least one sheet by bumping the at least one sheet against a reference wall,
- a sheet discharging unit that discharges the at least one sheet from the stacking unit in the sheet conveying direction, and
- a control unit that, when a predetermined condition is satisfied, sets a timing for the discharging unit to discharge the at least one sheet as the first aligning unit is setting the at least one sheet back in the direction opposite to the sheet conveying direction but prior to the first aligning unit successfully completing the bumping of the at least one sheet against the reference wall.
