摘要:
A sheet processing apparatus which is capable of accurately superimposing or aligning sheets discharged from an image forming apparatus during buffering even when the space intervals between the sheets are reduced. A sheet processing apparatus sequentially receives sheets discharged from an image forming apparatus and carries out post-processing on the sheets. During execution of the post-processing on the sheets, a plurality of sheets are discharged successively from the image forming apparatus and superimposed one upon another around a buffer roller. The conveying speed of the sheets is controlled such that a conveying time period over which a sheet preceding a final one of the sheets to be superimposed one upon another around the buffer roller is conveyed over a predetermined path section is shorter than a conveying time period over which the final one is conveyed over the predetermined path section.

A sheet handling apparatus is provided, which is comprised of a plurality of inserter trays for stacking thereon insert sheets to be inserted between recording sheets having images formed thereon. Sheet feeding modes for feeding insert sheets include two kinds, i.e. S-stacking mode and F-stacking mode, that can be set by a mode key displayed on a sheet feeding mode setting screen view. In the S-stacking mode, only first-page insert sheets are stacked on a first inserter tray, and only second-page insert sheets and third-page insert sheets are stacked on second and third inserter trays, respectively. In the F-stacking mode, insert sheets are stacked in order of page on an inserter tray. Sheet feeding is suitably controlled by stacking insert sheets on inserter trays in manners corresponding to respective selected stacking modes.

A sheet-thickness detector device has a sheet guide with a sheet-guide surface for guiding a sheet between a magnetic field sensor and a magnetic guide element. The magnetic field sensor, having an approach-guide plane disposed upstream in a sheet conveying direction for guiding the sheet to a detection surface, comes into direct contact with the sheet. By the structure mentioned above, the thickness of a sheet is detected so as to determine sheet double feeding and the like without producing sheet jamming.

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.
摘要:
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:
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.
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.
