The present invention relates to a sheet processing apparatus comprising an intermediate staking portion for aligning a sheet sent, a reference wall for positioning the sheet, a stapler form performing a binding operation with respect to a sheet bundle aligned by the reference wall, delivery means for delivering the sheet bundle from the intermediate stacking portion, a sheet stacking portion for stacking the sheet bundle and guide means provided above the sheet stacking portion and at an end portion on the stapler side of the end portions in the width direction of the sheet. The guide means supports an end portion on the stapler side of the sheet bundle when the sheet bundle is delivered from the delivery means in a staple mode in which the binding operation is preformed with respect to the sheet bundled.
摘要:
A sheet conveying apparatus including a conveying path changing device, the conveying path changing device having a main conveying path for conveying a sheet, a plurality of branched paths branched from the main conveying path, a plurality of oscillatable flappers for selecting between a changed position where the sheet is guided from the main conveying path to one of the branched paths and a retracted position permitting passage of the sheet, a single solenoid for oscillating the plurality of flappers, a single link for connecting the solenoid and the flappers, and a sensor confirming movements of the flapper by detecting a movement of the link.
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.
摘要:
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.

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.
