Abstract
A sheet post-processing apparatus includes plural trays arranged along a sheet conveyance direction, wherein a sheet is stacked, bridging between the plural trays, wherein a post-processing is effected to the sheet in a part of the plural trays; a controller for controlling the trays to provide a level difference between the trays by lowering another one of the trays than the one of the trays; and aligning device for laterally aligning the sheet stacked, bridging between the trays providing the level difference.
Claims15
A sheet post-processing apparatus, comprising:
- plural trays arranged along a sheet conveyance direction, wherein a sheet is stacked bridging between the plural trays, and wherein the sheet is post-processed in a part of the plural trays;
- means for controlling said trays to provide a level difference between a portion of the sheet on one of said trays and another portion of the sheet on another one of said trays by a lowering of said another tray in relation to said one of the trays;
- and
- aligning means for laterally aligning the sheet stacked, bridging between said trays providing the level difference.
A sheet post-processing apparatus, comprising:
- means for receiving a sheet on which an image has been formed;
- a processing tray, disposed downstream of said receiving means with respect to a conveyance direction of the sheet, to receive the sheet;
- a sheet accommodating tray, disposed downstream of said processing tray with respect to the same direction, to stack the sheet;
- means for substantially vertically moving said sheet accommodating tray;
- means, associated with said processing tray, to post-process the sheet;
- and
- control means for controlling said vertical movement means to lower said sheet accommodating tray to provide a level difference between said processing tray and said sheet accommodating tray when the sheet is stacked on and bridging the processing tray and the sheet accommodating tray for the post-processing.
An image forming apparatus, comprising:
- sheet feeding means for feeding a sheet;
- image forming means for forming an image on a sheet fed by said sheet feeding means;
- conveying means for conveying the sheet on which the image has been formed;
- means for receiving the sheet conveyed by said conveying means;
- a processing tray, disposed downstream of said receiving means with respect to a conveyance direction of the sheet, to receive the sheet;
- a sheet accommodating tray, disposed downstream of said processing tray with respect to the same direction, to stack the sheet;
- means for substantially vertically moving said sheet accommodating tray;
- means, associated with said processing tray, to post-process the sheet;
- and
- control means for controlling said vertical movement means to lower said sheet accommodating tray to provide a level difference between said processing tray and said sheet accommodating tray when the sheet is stacked on and bridging the processing tray and the sheet accommodating tray for the post-processing.
An image forming apparatus provided with a sheet post-processing apparatus, comprising:
- plural trays arranged along a sheet conveyance direction, wherein a sheet is stacked, bridging between the plural trays, wherein a post-processing is effected on the sheet in a part of the plural trays;
- means for controlling said trays to provide a level difference between a portion of the sheet on one of said trays and another portion of the sheet on another one of said trays by a lowering of said another tray in relation to said one of the trays;
- and
- aligning means for laterally aligning the sheet stacked, bridging between said trays providing the level difference.
