A sheet processing apparatus includes a first intermediate stacking portion which stacks a conveyed sheet and which performs process to the sheet, a stapler which performs process to the sheet on the first intermediate stacking portion, a second intermediate stacking portion which is located on an upstream side in a conveying direction of the stapler and which is capable of temporarily storing the conveyed sheet, and an intermediate roller pair which conveys the sheet on the second intermediate stacking portion to the first intermediate stacking portion. The sheet stacked on the first intermediate stacking portion and the sheet temporarily stored in the second intermediate stacking portion overlap each other.

An image processing apparatus ejects the sheet to witch image processing unit perform to an ejection tray or a staple stacker by a pair of ejection rollers and the like. A sheet path for guiding the sheet to the ejection rollers is opened and closed in conjunction with slide movement of the ejection tray when the ejection tray is attached to a main body of the apparatus, and the sheet path is opened and closed in conjunction with the slide movement of a staple stacker when the staple stacker is attached to the main body of the apparatus.

Provided are a post-processing device, an image forming apparatus having the post-processing device and an error handling method therefor. A conveyed sheet is temporarily stacked on a pair of slide guides (310, 311), and after post-processing such as stapling is conducted on the sheets, the slide guides (310, 311) are opened to drop down the sheets on a face-down discharge portion (125) on an upper surface of a printer (100). If the number of sheets temporarily stacked on the slide guides (310, 311) exceeds the post-processing possible number of sheets, the slide guides (310, 311) are opened to drop down the sheets on the face-down discharge portion (125). If the size of sheets to be post-processed is unsuitable for the post-processing, a flapper (301) is changed over so that the sheets transported from the printer main body (100) are discharged directly to the face-down discharge portion (125) and stacked thereon.

A cover for forming an outer appearance of a stapler unit for performing a stapling process to a sheet bundle serves also as a part of an outer shell of an apparatus body, and the stapler unit is provided selectively to the apparatus body movably between a position for stapling the sheet bundle and a position for replacing staple cartridges, to thereby make it possible to readily perform a jam process or staple replacement.
摘要:
A sheet processing apparatus including a stacking portion for stacking sheets, an alignment reference wall disposed in approximately parallel with a conveying direction of the sheet, an alignment moving wall for performing alignment by making an end portion of the sheet hit with the alignment reference wall, a processing mechanical section for carrying out binding with respect to the sheet bundle thus aligned, and a plurality of rotating pairs disposed in a widthwise direction approximately perpendicular to the conveying direction of the sheet for conveying the sheet bundle in a pinching manner. The sheet processing apparatus is capable of performing a process such as binding in the processing mechanical section after the sheet bundle which has been aligned by the alignment reference wall and the alignment moving wall is conveyed by a predetermined distance by the rotating pairs, and it is characterized in that each of the plurality of the rotating pairs disposed in the sheet widthwise direction has a pressure different from that of other rotating pairs for pinching the sheet.

A discharged sheet stacking apparatus includes a sheet feed-in device for pinching and feeding a sheet onto a sheet stacking portion on which a plurality of sheets are stacked and for causing a tip end of the sheet to abut against a sheet stopper. The sheet feed in device is disposed at a position spaced apart from the sheet stopper by a distance smaller than a length of the sheet. The sheet feed-in device continues the feeding operation while pinching a tail end of the sheet even after the tip end of the sheet abuts against the sheet stopper so that, after a loop is formed in the tail end of the sheet, the sheet is discharged onto the sheet stacking portion.

This invention relates to a sheet fastening apparatus comprising sheet bundle conveying means for conveying sheet bundles and sheet bundle fastening means for fastening sheet bundles. The sheet bundle fastening means is disposed on either side, of the sheet bundle, extending substantially parallel in a sheet conveyance direction and fastens the sheet bundle at least at a position upon stop of conveyance of the sheet bundle by the sheet bundle conveying means.
