At the point in time when it is determined that the number of sheets constituting one sheet bundle exceeds the maximum number of sheets that can be crimp-bound, a sheet bundle that has already been shifted to a crimp-binding position is discharged to a crimp-binding discharge position without being subjected to crimp-binding. Thereafter, succeeding sheets are shifted as a bundle to the crimp-binding position and discharged to the crimp-binding discharge position without being subjected to crimp-binding.

A postprocessing apparatus includes a horizontal alignment plate, a binder, a tray, and a shift actuator assembly. The horizontal alignment plate is positioned to align sheets in a sheet width direction. The binder binds sheets to form bound sheet bundles. The bound sheet bundles are stacked on the tray. The shift actuator assembly shifts the bound sheet bundles in the sheet width direction. A postprocessing controller controls the shift actuator assembly to shift the bound sheet bundles such that swollen portions of the bound sheet bundles are shifted inward of the horizontal alignment plate in the sheet width direction when the processed sheets are piled on the tray to the vicinity of the horizontal alignment plate.

A sheet discharging apparatus includes a stacking portion, a first conveyance portion, a detection portion, a second conveyance portion, a third conveyance portion, and a control portion. The control portion is configured to execute a discharge operation by causing the sheet discharging apparatus to reverse a conveyance direction of a first sheet conveyed from the first conveyance portion to the second conveyance portion and deliver the first sheet to the third conveyance portion by using the second conveyance portion, convey the first sheet toward the second conveyance portion by the third conveyance portion, and discharge the first sheet and the second sheet to the stacking portion by using the second conveyance portion in a state where the first sheet and the second sheet are superimposed on each other.

A paper sheet S is intermittently transported by a transport mechanism 6 and each processing unit 7, 8 operates while the transport mechanism pauses the transport operation. An information acquisition unit 9 obtains paper information from the paper sheet. A control unit 10 stores the paper information of the paper sheet to be processed for each processing unit, updates the data of the memory in a manner such that the paper information of the paper sheet associated with the previous processing unit is associated with the next processing unit every time the transport mechanism transports, and configures the settings of each processing unit for the next processing operation based on the paper information every time the processing operation of the processing unit is completed.

A stacker includes a medium stacking portion for receiving and stacking a medium processed and discharged by a processing unit, a medium butting portion for aligning the medium by contacting a leading end of the medium, and a paddle that includes a feeding portion and is for transporting the medium received by the medium stacking portion in a direction toward the medium butting portion by rotating. Furthermore, the stacker has a first mode in which the paddle stops in a state in which the feeding portion does not contact the medium on the medium stacking portion and a second mode in which the paddle stops in a state in which the feeding portion comes into contact with the medium on the medium stacking portion and is deformed.

The present invention relates to a transfer module (26) for a folder-gluer machine (1), the transfer module comprising a lower conveyor (36) and an upper conveyor (38) adapted to receive a folding box (2) therebetween and to transport the folding box in a direction of transportation (D) towards a downstream-located loading surface (90) in a stacker module. The upper conveyor (36) of the transfer module extends further in the direction of transportation than the lower conveyor (38) and the lower conveyor comprises a first conveyor belt (38a) and second conveyor belt (38b), each having an inlet end (67a, 67b) and an outlet end (65a, 65b), and wherein the outlet ends are displaceable in the direction of transportation.

A sheet processing device includes a stacking member configured to stack a sheet, a discharging member configured to discharge the sheet stacked on the stacking member, a discharging tray on which the sheet discharged by the discharging member is stacked, a pushing-out member configured to push out the sheet from the stacking member toward the discharging member by being moved in a pushing-out direction, and a controller configured to select, on the basis of information of the sheet stacked on the stacking member, whether to move the pushing-out member to which position of a first position and a second position positioned on a side downstream of the first position with respect to the pushing-out direction.

The inkjet image forming device comprises a post-processing device to post-process the paper ejected from the print engine, wherein the post-processing device comprises a loading part in which the paper conveyed from the print engine is to be loaded, and an air blower including an air blowing part to blow air toward the loading part, and a shutter to be rotatable between a closed position and an open position in the air blowing part to adjust an amount of air to be blown from the air blowing part.

A post-processing device includes a loading unit on which a sheet is loaded, a first transport unit configured to apply, to the sheet loaded on the loading unit, a transport force toward an alignment unit, a second transport unit located between the first transport unit and the alignment unit, and configured to apply, to the sheet, a transport force toward the alignment unit, a control unit configured to control rotation operation of the second transport unit, and a post-processing unit configured to perform post-processing on the sheet transported to the alignment unit, wherein the post-processing unit is configured to execute a plurality of types of the post-processing, and the control unit is configured to control the rotation operation of the second transport unit in accordance with the type of the post-processing.

A sheet alignment apparatus includes a supporting portion configured to support a sheet, a first alignment member configured to abut an end portion in a first direction of the sheet supported by the supporting portion and align a position of the sheet in the first direction, a first moving unit configured to move the first alignment member in the first direction, a second alignment member configured to abut an end portion in a second direction of the sheet supported by the supporting portion and align a position of the sheet in the second direction, the second direction being perpendicular to the first direction, and a second moving unit configured to move the second alignment member in the second direction, wherein the first moving unit is disposed below the supporting portion, and wherein the second moving unit is disposed above the supporting portion.
