| 20080296826 | INTERMEDIATE CONVEYING APPARATUS - A conveyance control device of an intermediate conveying apparatus calculates the number of sweets finished in terms of processing, based on information about the number of superposed sheets for one set and about the number of sets finished in terms of processing received from the post-processing apparatus, and controls to transmit the calculated number of sheets to the aforesaid image forming apparatus. | 12-04-2008 |
| 20100171256 | Sheet Processing Apparatus and Image Forming Apparatus - The present invention provides a sheet processing apparatus that can prevent, with higher certainty, lift of the trailing end of each sheet placed in sheet stacking portion. This apparatus includes a first holding member and a second holding member that prevent lift of the trailing end of each sheet from an intermediate stacking portion. When introduced to the intermediate stacking portion, the subsequent sheet comes into contact with the first holding member, so that the first holding member moves to the retracting position. As the subsequent sheet continues to be conveyed, the subsequent sheet comes into contact with the second holding member, so that the second holding member moves from the restricting position to the retracting position. As the trailing end of the sheet is introduced, the first holding member moves from the retracting position to the restricting position, to hold down the trailing end of the sheet. | 07-08-2010 |
| 20110031675 | STAPLING UNIT, SHEET FINISHING APPARATUS, AND STAPLING METHOD - Certain embodiments provide a stapling unit including a stapler, a processing tray, a stapler moving mechanism, a sensor configured to scan sheets in a sheet width direction, and a controller configured to drive the stapler. The controller measures sheet width of the sheets according to an output of the sensor. The controller calculates a center position between other two sheet edges each orthogonal to a sheet edge where the stapler drives staples into stapling positions. The controller allocates the stapling positions in the two places with reference to the center position. The controller moves the stapler moving mechanism to the stapling positions. | 02-10-2011 |
| 20160052320 | PRINTING APPARATUS AND METHOD OF CONTROLLING THE SAME, AND STORAGE MEDIUM - A technique by which when printing is initiated, printed sheets remaining in a large-volume stacker and sheets printed in a subsequent job are not mixed in the large-volume stacker is provided. A printing system in which a printing apparatus and a post-processing apparatus for receiving a sheet printed by the printing apparatus and performing post-processing are connected, upon activation of the printing system, when detecting that a sheet is stacked in the post-processing apparatus, instructs the processing apparatus to discharge the remaining sheet. | 02-25-2016 |
| 20160185563 | SHEET PROCESSING APPARATUS, METHOD FOR CONTROLLING SHEET PROCESSING APPARATUS, AND STORAGE MEDIUM - A sheet processing apparatus includes a stapler that executes a stapling process on sheets set in a sheet insertion opening by a user, and a sheet detecting sensor that detects the sheets set in the sheet insertion opening. The sheet processing apparatus displays a setting screen for setting a time until the staple process is executed, and causes the stapler to execute the stapling process according to elapse of the set time after the sheet detecting sensor detects the sheets. | 06-30-2016 |
| 270580030 | Mis-fed sheet sensor | 5 |
| 20080308987 | SHEET PROCESSING APPARATUS AND SHEET PROCESSING METHOD - A sheet processing apparatus includes a first detecting unit including a first sensor and a second sensor arranged at a predetermined spacing from each other on a line orthogonal to a conveying path through which a sheet is conveyed, and a hole punching section provided downstream at a predetermined distance from the first detecting unit and arranged orthogonally to the conveying path of the sheet. The quantity of skew of the sheet is detected in accordance with a difference between time when a forward edge or a rear edge of the sheet passing through the conveying path passes the first sensor and time when the forward edge or rear edge passes the second sensor. Position information of the sheet with respect to the hole punching section is calculated in accordance with information of timing when the first sensor and the second sensor detect the passage of the sheet edge, and the conveying speed of the sheet. | 12-18-2008 |
| 20090243179 | POCKET MANAGEMENT SYSTEM - A system uses a plurality of sensors to detect and manage conditions within a moving pocket, such as a pocket carrying a flat product from one location to another. The system is particularly useful in connection with a newspaper insert machine. One sensor detects whether the product has been opened properly at a particular time; another sensor detects whether the product has been properly gripped by a gripper at a particular time; another sensor detects whether the pocket is empty at a particular time and another sensor detects whether the pocket is open or closed at a particular time. In the event an error condition is detected, the error condition is corrected by a control system. | 10-01-2009 |
| 20090243180 | SHEET PROCESSING APPARATUS AND IMAGE FORMING SYSTEM - An image forming system which is capable of preventing paper jam from occurring in a sheet processing apparatus to thereby maintain the stability of the system. An alignment plates of an alignment unit movable in a lateral direction each sheet are brought into abutment with opposite side edges of sheets stacked on the sheet stack unit to laterally align the sheets. A lateral registration sensor unit detects a lateral position of the sheet being conveyed. When the detected lateral position of the sheet is beyond a predetermined position, the CPU of the apparatus changes the standby positions of the alignment plates such that spacing therebetween in the lateral direction the sheet is widened by a predetermined amount, and extends the conveying interval of sheets in the image forming apparatus by a predetermined time period. | 10-01-2009 |
| 20090267282 | SHEET PROCESS APPARATUS - Provided is a shift transport device for transporting a sheet to a sheet transport direction upstream side of a sheet process tray and for shifting the sheet. The shift transport device offsets the sheet and the sheets are stacked on a sheet process tray. Then, the sheets stacked on the sheet process tray in a state of being offset are aligned by an aligning member. | 10-29-2009 |
| 20220135362 | SHEET CONVEYING APPARATUS - The present invention is to provide a sheet conveying apparatus capable of reliably detecting a full-load state of a storage section for storing sheets discharged from a sheet conveyance path when an abnormality such as multi feed is detected, a sheet feed apparatus is provided with a multi feed sheet storage section disposed below a common conveyance path to store multi-fed sheets with multi feed detected, and a flap member rotating between a first rotation position for supporting a sheet in the common conveyance path to be able to convey to the downstream side in a conveyance direction, and a second rotation position for guiding to the multi feed sheet storage section, and determines that the multi feed sheet storage section is in a full-load state in detecting that the flap member does not return to the first rotation position. | 05-05-2022 |
