  • Patent number: 12600594
    Abstract: A sheet dropping portion abuts on a sheet conveyed in a first conveyance direction by a pair of conveyance rotary members from above to drop the sheet onto a placement portion by pivoting from an upper position to a lower position. The guide portion is arranged above the placement portion and extends toward the placement portion, and guides the sheet toward an abutment portion in a case where the sheet on the placement portion conveyed in a second conveyance direction opposite to the first conveyance direction by a reverse conveyance portion comes into contact with the guide portion. The sheet dropping portion located at the lower position overlaps a part of the guide portion when viewed in a rotational axis direction of the pair of conveyance rotary members.

  • Patent number: 12441577
    Abstract: In a binding discharge process, a binding process is performed on a plurality of sheets positioned at a binding position by repeating a process in which, after a conveyed sheet is conveyed in a reverse direction on a placement portion by a second conveyance portion to cause a downstream end of the sheet to abut an abutment portion, the sheet is moved in a shift direction and positioned at the binding position by a first shifting portion, and the plurality of sheets subjected to the binding process are discharged onto the stacking portion by a discharge portion. In a switchbackless shift discharge process, the conveyed sheet is shifted in the shift direction by the first shifting portion by driving a driving portion without conveying the sheet in the reverse direction by the second conveyance portion, and is discharged onto the stacking portion by the discharge portion.
