Abstract

A sheet processing apparatus includes alignment plates, which are provided outside a main body housing of a sheet processing apparatus, shift in an alignment direction orthogonal to a transport direction of a sheet loaded on a load tray to load sheets discharged from a discharge opening, and align opposite sides of the sheet, and a sheet support surface provided in a different position adjacent to a processing tray in the alignment direction to support sheets inserted from a manual feed opening provided outside the main body housing. A binding apparatus shifts to the processing tray or the sheet support surface, and binds sheets placed on the processing tray or the sheet support surface. Neat alignment plates are positioned not to block the manual feed opening during the binding processing on manually fed sheets on the sheet support surface.

First claim

The invention claimed is:

1. A sheet processing apparatus comprising:
a transport path adapted to transport a sheet in a predetermined transport direction;
a processing tray adapted to place the sheet transported from the transport path;
a binding processing apparatus adapted to perform binding processing on sheets placed on the processing tray;
a discharge opening adapted to discharge the sheet from the processing tray to outside an apparatus main body housing;
a load tray provided on a downstream side of the processing tray in the transport direction to load sheets discharged from the discharge opening;
neat alignment plates provided outside the main body housing to shift in a width direction orthogonal to the transport direction of the sheet loaded on the load tray and align opposite sides of the sheet;
a sheet support surface provided in a different position adjacent to the processing tray in the width direction to support a sheet inserted from a manual feed opening provided outside the main body housing; and
a width-direction drive mechanism adapted to shift the neat alignment plates in the width direction,
wherein the binding processing apparatus shifts to the processing tray and the sheet support surface, and is provided to be able to perform the binding processing on sheets placed on the processing tray or the sheet support surface, and
the apparatus is further provided with a regulation member for regulating so that the neat alignment plates do not overlap with the manual feed opening in the width direction viewed from a downstream side of the transport direction, during the binding processing for manually fed sheets on the sheet support surface.

2. The sheet processing apparatus according to claim 1 , wherein the regulation member is a regulation portion that comes into contact with the neat alignment plates to regulate so that a movable range of the neat alignment plates by the width-direction drive mechanism does not overlap with a downstream side of a manual binding processing section viewed from the downstream side of the transport direction.

3. The sheet processing apparatus according to claim 1 , wherein the regulation member is a controller for controlling the width-direction drive mechanism so that the neat alignment plates are positioned in positions not to overlap with the manual feed opening viewed from the downstream side of the transport direction during the binding processing on manually inserted sheets on the sheet support surface.

4. The sheet processing apparatus according to claim 1 , wherein a surface positioned on the manual feed opening side of one of the neat alignment plates positioned on the manual feed opening side is set to be substantially parallel with a regulation surface positioned on the discharge opening side in inserting a sheet in the manual feed opening.

5. The sheet processing apparatus according to claim 4 , wherein when the one of the neat alignment plates on the manual feed opening side shifts to a manual feed opening-side limit position in a movable range, the surface positioned on the manual feed opening side regulates the sheet inserted in the manual feed opening.

6. The sheet processing apparatus according to claim 5 , further comprising:
a neat alignment control section adapted to set, a position in the width direction of the one of the neat alignment plates positioned on the manual feed opening side in the pair of neat alignment plates, on the discharge opening side rather than the manual feed opening side, in a mode for allowing the binding processing to be performed on sheets supported by the sheet support surface.

7. The sheet processing apparatus according to claim 4 , further comprising:
a neat shaft member supported by a neat housing;
a rotation drive mechanism disposed inside the neat housing to rotate the pair of neat alignment plates around the neat shaft member; and
a neat alignment control section adapted to control operation of the width-direction drive mechanism and the rotation drive mechanism.

8. The sheet processing apparatus according to claim 7 , wherein in a mode for allowing the binding processing to be performed on sheets supported by the sheet support surface, the neat alignment control section controls the rotation drive mechanism so that the neat alignment plates are positioned in retract positions.

9. The sheet processing apparatus according to claim 7 , wherein in a mode for allowing the binding processing to be performed on sheets supported by the sheet support surface, the neat alignment control section controls the rotation drive mechanism so that the neat alignment plates are positioned in operation positions.

10. The sheet processing apparatus according to claim 1 , wherein the neat alignment plates are provided in a neat housing attached above the discharge opening and the manual feed opening, on the downstream side in the transport direction, outside the main body housing.

11. The sheet processing apparatus according to claim 1 , wherein a neat housing is provided with a scraping apparatus for scraping the sheet discharged from the discharge opening onto the load tray by a rotating member, and
a neat alignment control section controls the scraping apparatus.

12. An image forming system comprising:
an image forming apparatus adapted to form an image on a sheet and carry out the sheet with the image formed; and
the sheet processing apparatus according to claim 1 adapted to perform post-processing on the sheet carried out of the image forming apparatus.

13. An image forming system comprising:
an image forming apparatus adapted to form an image on a sheet and carry out the sheet with the image formed; and
the sheet processing apparatus according to claim 11 adapted to perform post-processing on the sheet carried out of the image forming apparatus.

14. A sheet processing apparatus comprising:
a transport path adapted to transport a sheet in a predetermined transport direction;
a processing tray adapted to place the sheet transported from the transport path;
a binding processing apparatus adapted to perform binding processing on sheets placed on the processing tray;
a discharge opening adapted to discharge the sheet from the processing tray to outside an apparatus main body housing;
a load tray provided on a downstream side of the processing tray in the transport direction to load sheets discharged from the discharge opening;
neat alignment plates provided outside the main body housing to shift in a width direction orthogonal to the transport direction of the sheet loaded on the load tray and align opposite sides of the sheet;
a sheet support surface provided in a different position adjacent to the processing tray in the width direction to support a sheet inserted from a manual feed opening provided outside the main body housing;
a sheet regulation surface for regulating an end of a sheet supported on the sheet support surface; and
a width-direction drive mechanism adapted to shift the neat alignment plates in the width direction,
wherein the binding processing apparatus shifts to the processing tray and the sheet support surface, and is provided to be able to perform the binding processing on sheets placed on the processing tray or the sheet support surface, and
the apparatus is further provided with a regulation member for regulating so that the neat alignment plates do not move beyond the sheet regulation surface in the width direction and are located at a side of the processing tray, during the binding processing for manually fed sheets on the sheet support surface.
