Abstract

A recording material processing apparatus includes: a first stacking unit configured to stack a recording material; a second stacking unit provided on a downstream side of the first stacking unit in a conveyance direction of the recording material; an alignment unit configured to align the recording material stacked in the first stacking unit before the recording material is discharged to the second stacking unit; and a control unit configured to perform control of discharging the recording material to the second stacking unit by switching between first control not to align the recording material by the alignment unit and second control to align the recording material by the alignment unit.

First claim

What is claimed is:

1. A recording material processing apparatus comprising:
a conveyance unit configured to convey a recording material;
an alignment unit including a first alignment member and a second alignment member, the first alignment member and the second alignment member being configured to support the recording material conveyed by the conveyance unit, wherein at least the first alignment member approaches the second alignment member to align the supported recording material in a direction perpendicular to a conveyance direction of the recording material;
a stacking unit on which the recording material is stacked, wherein the supported recording material is discharged to the stacking unit when at least the first alignment member separates from the second alignment member; and
a control unit configured to perform control of discharging the recording material to the stacking unit by switching between a first control not to align the recording material by the alignment unit and a second control to align the recording material by the alignment unit,
wherein, in a case where the control unit performs the first control after performing the second control, the control unit is further configured not to discharge the recording material supported by the alignment unit to the stacking unit at the end of the second control, and
wherein, in a case where the control unit does not perform the first control after performing the second control, the control unit is further configured to discharge the recording material supported by the alignment unit to the stacking unit at the end of the second control.

2. The apparatus according to claim 1 , wherein the control unit is further configured to stack a recording material over the recording material supported by the alignment unit, in the first control performed after the second control.

3. The apparatus according to claim 2 , wherein the control unit is further configured to discharge the recording material supported by the alignment unit to the stacking unit at the end of the first control performed after the second control.

4. The apparatus according to claim 1 , wherein the control unit is further configured to perform control to discharge the recording material to the stacking unit by switching, for a unit of processing, the first control and the second control.

5. The apparatus according to claim 4 , further comprising a controller configured to notify the control unit of the unit of processing.

6. The apparatus according to claim 5 , wherein the controller is further configured to determine the unit of processing based on a print job designated by a user.

7. The apparatus according to claim 1 , wherein the control unit is further configured to monitor a number of recording materials supported by the alignment unit.

8. The apparatus according to claim 7 , wherein the control unit is further configured to discharge the recording material supported by the alignment unit to the stacking unit when the number of the recording materials supported by the alignment unit reaches a threshold.

9. The apparatus according to claim 1 , wherein the first alignment member is further configured to support one end of the recording material in the direction perpendicular to the conveyance direction, and
the second alignment member is further configured to support the other end of the recording material in the direction perpendicular to the conveyance direction.

10. The apparatus according to claim 1 , further comprising an intermediate stacking unit configured to support the recording material conveyed by the conveyance unit together with the first alignment member and the second alignment member.

11. The apparatus according to claim 10 , further comprising a discharging roller movable between a first position and a second position, the discharging roller being in contact with the recording material supported by the first alignment member, the second alignment member and the intermediate stacking unit at the first position, and not in contact with the recording material at the second position,
wherein the supported recording material is discharged to the stacking unit when the first alignment member separates from the second alignment member and the discharging roller moves to the first position and rotates.

12. An image forming apparatus comprising:
an image forming unit configured to form an image on a recording material;
a conveyance unit configured to convey the recording material on which the image has been formed;
a recording material processing unit that includes:
an alignment unit including a first alignment member and a second alignment member, the first alignment member and the second alignment member being configured to support the recording material conveyed by the conveyance unit, wherein at least the first alignment member approaches the second alignment member to align the supported recording material in a direction perpendicular to a conveyance direction of the recording material, and
a stacking unit on which the recording material is stacked, wherein the supported recording material is discharged to the stacking unit when at least the first alignment member separates from the second alignment member; and

a control unit configured to perform control of discharging the recording material to the stacking unit by switching between a first control not to align the recording material by the alignment unit and a second control to align the recording material by the alignment unit,
wherein, in a case where the control unit performs the first control after performing the second control, the control unit is further configured not to discharge the recording material supported by the alignment unit to the stacking unit at the end of the second control, and
wherein, in a case where the control unit does not perform the first control after performing the second control, the control unit is further configured to discharge the recording material supported by the alignment unit to the stacking unit at the end of the second control.

13. The apparatus according to claim 12 , wherein the control unit is further configured to stack a recording material over the recording material supported by the alignment unit in the first control performed after the second control.

14. The apparatus according to claim 13 , wherein the control unit is further configured to discharge the recording material supported by the alignment unit to the stacking unit at the end of the first control performed after the second control.

15. The apparatus according to claim 12 , wherein the first alignment member is further configured to support one end of the recording material in the direction perpendicular to the conveyance direction, and
wherein the second alignment member is further configured to support the other end of the recording material in the direction perpendicular to the conveyance direction.

16. The apparatus according to claim 12 , further comprising an intermediate stacking unit configured to support the recording material conveyed by the conveyance unit together with the first alignment member and the second alignment member.

17. The apparatus according to claim 16 , further comprising a discharging roller movable between a first position and a second position, the discharging roller being in contact with the recording material supported by the first alignment member, the second alignment member and the intermediate stacking unit at the first position, and not in contact with the recording material at the second position,
wherein the supported recording
