[0037] As shown, FIG. 7 gradually increasing the post-processing until the post-processing time of the chromatic mode T ₁ from 0 to X ₀ in, constant driving from T ₁ to a slight front of T ₃ of T ₂ a panel rate X _0, from T ₃ to T ₂ are gradually reduced to X2, it is discharged by driving at a constant X2 from T ₂ to T ₄ after slightly. According to the drive control modes of the respective motors, the set sheets are discharged onto the stacking tray without any looseness.

As described above, even in the single sheet mode, the sheet is first discharged to the collecting tray and then discharged to the stacking tray. In the post-processing mode for two or more sheets, the sheets discharged to the collecting tray are aligned. After that, post-processing such as binding is performed, the sheets are ejected as a set, and stacked on a stacking tray. Even in the non-post-processing mode, the sheet is once discharged to the editing tray, discharged after being set in the paper alignment, and stacked on the stacking tray.

Thus, regardless of the presence or absence of post-processing,
A sheet in a correct posture and aligned set is discharged onto the stacking tray, which facilitates subsequent handling by the operator.

As described above, according to the present invention,
Even when the mode in which post-processing is not performed is selected, a plurality of sheets can be discharged to the stacking tray in a state where the sheets are aligned, that is, the sheets are aligned, and even if only one sheet is copied, the sheets are aligned and discharged. It is possible to provide a high-speed and compact sheet post-processing apparatus that can perform the processing.

Claims (3)

[Claims] 1. A sheet post-processing apparatus for performing post-processing such as binding or punching on a sheet discharged from an image forming unit, comprising: a sheet shifting paddle and a sheet for aligning the sheet discharged from the image forming unit. An editing tray having at least an alignment plate, a sheet post-processing machine installed at a rear end of the editing tray, a loading tray for loading sheets discharged from the editing tray, and an loading tray installed above the editing tray And a set discharging device for discharging a sheet set aligned on the editing tray to the stacking tray, and irrespective of whether or not the sheet discharged from the image forming unit is post-processed by the sheet post-processing machine. A sheet post-processing device, wherein the sheet is set and discharged to the stacking tray via an editing tray. 2. A paper post-processing control method for performing post-processing such as binding or punching on paper discharged from an image forming unit, wherein the first controller controls the image forming unit based on set image forming parameters. A second controller that controls a sheet post-processing device according to parameters set in the first controller, a post-processing control unit that controls the post-processing machine, a paddle control unit, a matching plate control unit, A set ejection control unit; and a paper press control unit. The first controller operates the paddle control unit and the matching plate control unit in the post-processing non-operation mode in the same manner as in the post-processing mode. A sheet post-processing control method characterized by operating a discharge control means. 3. The apparatus according to claim 2, further comprising a set discharge speed changing unit for changing a discharge speed of the set discharge control unit, wherein the discharge speed of the set discharge control unit is changed to a plurality of values during the set discharge. Characteristic paper post-processing control method.
