摘要： A sheet conveyance apparatus capable of detecting a sheet end portion in a short time period even if sheets are conveyed at a narrow interval and at high speed, thus making it possible to expedite the start timing of a subsequent sheet alignment operation. In accordance with results of detection by lateral registration detection sensors performed when a sheet reaches a lateral registration detection sensor unit, the sensor unit is moved in a width direction for sheet end detection. Based on a moving distance of the sensor unit from a standby position to a position where the sheet end is detected, a shift amount to be shifted the sheet in the width direction, i.e., a lateral registration error, is computed.

摘要： A sheet stacking apparatus which is capable of efficiently stacking sheets of various sizes while efficiently using space therein to thereby realize compactness thereof, and maintaining a high availability. Stacker trays for stacking sheets discharged from an image forming apparatus can be separately removed. It is detected whether any of the stacker trays is removed. When large-size sheets are stacked, a stacker control section causes the stacker trays to operate as one tray to stack the sheets in a state extending on the stacker trays, whereas when small-size sheets are stacked, the section causes one of the stacker trays to stack the sheets. Further, when one stacker tray is removed to make it impossible to stack the large-size sheets, the section causes a display section to display a guide message advising setting of the removed stacker tray.

摘要： A sheet processing system capable of performing lateral shift correction of a sheet in an upstream sheet processing apparatus based on an amount of lateral shift to be caused by conveying thereof into a downstream sheet processing apparatus. A side edge sensor of a stacker detects a lateral shift amount of a sheet conveyed into the stacker. A stacker controller corrects lateral shift of the sheet by a shift unit. A side edge sensor of a finisher disposed downstream of the stacker detects a lateral shift amount of a sheet conveyed into the finisher. The finisher sends the detected lateral shift amount to the stacker. The stacker receives the lateral shift amount from the finisher, and the stacker controller corrects lateral shift of subsequent sheets based on both the lateral shift amount detected in the stacker and the lateral shift amount sent from the finisher.

摘要： A sheet processing apparatus includes a folding roller pair, a sheet pushing member, a detection unit, and a control unit. The folding roller pair folds a sheet or a sheet bundle by a nip portion and conveys a folded sheet or a folded sheet bundle. The sheet pushing member performs a pushing operation in which a tip of the sheet pushing member pushes the sheet or the sheet bundle into the nip portion of the folding roller pair. The detection unit detects whether the tip of the sheet pushing member reaches a predetermined position in a moving direction of the sheet pushing member. The control unit controls driving of the sheet pushing member according to a result of detection by the detection unit such that the sheet pushing member repeats the pushing operation until the detection unit detects that the tip of the sheet pushing member reaches the predetermined position.

摘要： A sheet processing apparatus includes a folding roller pair, a sheet pushing member, and a detection unit. The folding roller pair folds a sheet or a sheet bundle by a nip portion. The sheet pushing member results in a tip pushing a portion between two ends of the sheet or sheet bundle into the nip portion and then performs a tip returning operation. The detection unit detects whether the tip reaches a predetermined position within a predetermined time. When the tip does not reach the predetermined position within the predetermined time, the sheet pushing member retries the pushing operation after performing the returning operation. When the tip reaches the predetermined position within the predetermined time, the sheet pushing member stops the pushing operation and controls rotation driving of the folding roller pair such that the folding roller pair starts to convey the sheet or sheet bundle.

摘要： A sheet processing apparatus which is capable of improving the productivity of sheet processing as much as possible. An image forming apparatus forms an image on a sheet. A finisher is connected downstream of the image forming apparatus and performs post processing on the sheet. The finisher moves at least one of the sheet and a punching unit to adjust a position for punching holes in the sheet. The finisher determines whether or not a post-processing apparatus connected upstream of the finisher is provided with a correction mechanism for correcting a position of a sheet in a direction orthogonal to a sheet conveying direction. When the post-processing apparatus is provided with the correction mechanism, the finisher causes the image forming apparatus to be set such that a sheet conveying interval becomes shorter than when the post-processing apparatus is not provided with the correction mechanism.

摘要： A sheet processing apparatus includes a pushing member, a drive device, a first conveyance unit, a second conveyance unit provided on a downstream side of the first conveyance unit, a first detection unit, a second detection unit, and a control unit. The drive device moves the pushing member to push a portion of a sheet bundle to fold the sheet bundle. The first conveyance unit uses a roller pair to convey the folded sheet bundle folded. The second conveyance unit conveys the sheet bundle. The first detection unit detects an amount by which the pushing member is moved by the drive device. The second detection unit detects an amount by which the sheet bundle is conveyed by the first conveyance unit. The control unit separates the roller pair based on the amounts detected by the first and second detection units.
