Abstract
A postprocessing apparatus includes a support unit that supports a sheet that is transported, an abutment unit against which a leading end of the sheet supported by the support unit abuts, a postprocessing unit that performs a postprocessing operation on the sheet abutting against the abutment unit, a detection unit that detects an image formed at a predetermined position on the sheet and detects a position of the image when the sheet abuts against the abutment unit, and a changing unit that changes a position of the abutment unit relative to the postprocessing unit on the basis of the position of the image detected by the detection unit.
Claims6
A postprocessing apparatus comprising:
- a support unit that supports a sheet that is transported;
- an abutment unit against which a leading end of the sheet supported by the support unit abuts;
- a postprocessing unit that performs a postprocessing operation on the sheet abutting against the abutment unit;
- a detection unit that detects an image formed at a predetermined position on the sheet and detects a position of the image when the sheet abuts against the abutment unit;
- and
- a changing unit that changes a position of the abutment unit relative to the postprocessing unit on the basis of the position of the image detected by the detection unit.
An image forming system comprising:
- an image forming unit that forms an image on a sheet;
- a transport unit that transports the sheet on which the image forming unit has formed an image;
- a support unit that supports the sheet transported by the transport unit;
- an abutment unit against which a leading end of the sheet supported by the support unit abuts;
- a detection unit that detects an image formed at a predetermined position of the sheet and detects a position of the image when the sheet abuts against the abutment unit;
- and
- a driving unit that moves the abutment unit closer to or away from the support unit on the basis of the position of the image detected by the detection unit.
