Abstract
A sheet processing apparatus includes an endless belt configured to convey the sheet by coming in contact with an upper surface of the sheet stacked on the sheet stacking portion, a shaft extending in a direction orthogonal to the sheet conveying direction, and a supporting portion rotatably supporting the drive rotating member and supporting the endless belt through the drive rotating member. The supporting portion is configured to be swingable about the shaft and the endless belt is raised and lowered by the supporting portion being swung by a lifting portion.
Claims21
A sheet processing apparatus comprising:
- a sheet conveying portion configured to convey a sheet;
- a sheet stacking portion on which the sheet conveyed by the sheet conveying portion is stacked;
- an endless belt configured to convey the sheet by coming in contact with an upper surface of the sheet stacked on the sheet stacking portion;
- an aligning portion configured to align a position of the sheet in a sheet conveying direction of the sheet by abutting against an end of the sheet conveyed by the endless belt;
- a drive rotating member configured to rotate the endless belt while being in contact with the endless belt;
- a shaft extending in a direction orthogonal to the sheet conveying direction;
- a supporting portion configured to be swingable about the shaft, rotatably supporting the drive rotating member, and supporting the endless belt through the drive rotating member;
- and
- a lifting portion configured to raise and lower the endless belt by swinging the supporting portion.
