Even if a user sets an erroneous setting to a sheet, in order to provide an image formation system which can recycle sheets and improve operability without executing incorrect processing to the sheet, a reference value, which is referred in confirming an abnormal state of the sheet to be conveyed, before a generation of sheet size information is made to differ from the reference value after the generation of the sheet size information on the basis of a sheet detected result. In accordance with the sheet size information to be confirmed and the sheet size information acquired according to an instruction from an operator, processing corresponding to the instruction from the operator to the sheet is invalidated. An image formation operation is interrupted in accordance with the sheet size information to be confirmed and the sheet size information acquired according to the instruction from the operator.

An image forming apparatus has a sheet processing unit for feeding a cover sheet and a folder for folding the cover sheet with a bundle of recording sheets. The sheet processing unit has a cover sheet feeder for feeding a cover sheet facing upward toward an image forming unit, a reversing unit for reversing the cover sheet so that the cover sheet faces downward, and a conveyor for conveying the reversed cover sheet to the folder in a switchback manner so that the front face of the cover sheet faces the folding roller pair. The folder has a thrusting member for thrusting the bundle of sheets toward the folding roller pair and discharging the folded bundle to a discharge tray.

A sheet processing apparatus is provided, which is capable of achieving high quality processing and maintaining high productivity without giving rise to problems such as sheet jam or damage of sheets even when various sheets having different attributes are conveyed. A buffer roller 505 is inhibited from carrying out a sheet staying operation in accordance with the type of sheets conveyed from an upstream side of the apparatus, to be conveyed to a downstream side of the apparatus via the buffer roller 505.

An image forming apparatus has a sheet processing unit for feeding a cover sheet and a folder for folding the cover sheet with a bundle of recording sheets. The sheet processing unit has a cover sheet feeder for feeding a cover sheet facing upward in a first direction, a reversing unit for reversing the cover sheet so that the cover sheet faces downward, a conveyer for conveying the cover sheet in a second direction opposite the first direction and then conveying the cover sheet to the folder in the first direction. The folder has a thrusting member for thrusting the bundle of sheets toward the second direction and a folding roller pair for folding the bundle thrust by the thrusting member and discharging the folded bundle in the second direction.

To maintain high productivity and performing high-grade processes while minimizing deviation of a sheet process position in a direction at a right angle to a sheet conveying direction whatever types of sheets are to be processed, timing for starting detection of an end position of each of the sheets is controlled so as to execute the detection of the end position of each of the sheets at a vicinity of a sheet processing position on the sheet at which a sheet process is executed.

A sheet processor has a sheet transportation path, a punching unit for performing a punching operation on the sheets, the punching unit including a punch slide having a punch mechanism thereon, a moving device for moving the punch slide between a sheet punching operation position and a punch slide home position, the movement occurring in a direction transverse to the sheet transportation direction, and a detector for detecting completion of the punching operation by the punching unit. When the detector detects the completion of the punching operation, the moving device moves the punching unit to the punch slide home position.

Sheet processing apparatus including a process tray for stacking sheets received from an image forming apparatus, a jogger for jogging the sheet stacked on the process tray at one of two jogging positions, a discharge unit for discharging the sheet stacked on the process tray, and a discharge tray for stacking the sheets discharged by the discharge unit. The sheet processing apparatus includes a stapler for stapling the sheets stacked on the process tray, and a controller for controlling the stapler to staple the sheets at a stapling position corresponding to the jogging position by the jogger.
摘要:
A sheet processing apparatus, such as a finisher, to be used in an image forming device, has a sheet conveying device for allowing conveyance and temporary stopping conveyance to place the sheet in a waiting state, a sheet-conveying-condition detector for detecting a conveying condition for each sheet, a first mode of conveying a sheet by driving the sheet conveying device without placing the sheet conveying device in a waiting state, a second mode of conveyance which places the sheet conveying device in the waiting state, thereafter releasing the waiting state of the sheet conveying device in accordance with conveyance of a succeeding sheet, and conveying preceding and succeeding sheets in a superposed state, and a third mode of conveyance, placing the sheet conveying device in the waiting state, thereafter releasing the waiting state of the sheet conveying device, and conveying the preceding sheet separately from the succeeding sheet. A controller switches the sheet conveying device to the third mode when the sheet-conveying-condition detector has detected that a sheet having a different condition is included within a plurality of sheets to be discharged from the sheet conveying device in a superposed state in the second mode.
