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;
- 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;
- a first driving unit that moves the abutment unit closer to or away from the support unit in a vertical direction;
- and
- a second driving unit that moves the detection unit in a region located above the postprocessing unit, which performs the postprocessing operation on the sheet in the support unit, wherein the detection unit faces an upper end side of the support unit and is located above a middle of portion of the support 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 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 of the sheet and detects a position of the image when the sheet abuts against the abutment unit;
- a first driving unit that moves the abutment unit closer to or away from the support unit in a vertical direction on the basis of the position of the image detected by the detection unit;
- and
- a second driving unit that moves the detection unit in a region located above the postprocessing unit, which performs the postprocessing operation on the sheet in the support unit, wherein the detection unit faces an upper end side of the support unit and is located above a middle of portion of the support unit.
