The recording medium bundle subjected to the saddle stitching process and the half-folding process from the recording medium post-processing apparatus 100 enters the cutting unit 51 with the folding part at the top. When the sensor 54 provided upstream of the cutting means 51 detects the leading end portion of the recording medium bundle, the clamping means moving motor 24 of the moving means 2 determines the position based on the sheet size information and the cutting length information of the recording medium bundle. The conveyance roller pair 30 is rotated by the conveyance drive motor 33 of the recording medium conveyance means 3 after a fixed amount of rotation.
Next, based on the leading edge detection information of the recording medium bundle P of the recording medium detection sensor 34, the recording medium bundle is stopped when a predetermined amount is conveyed by the conveying roller pair 30. As shown in FIG. 5A, the stop position is at the nip portion of the additional folding roller 521 with the folded portion of the recording medium bundle, and the small edge at the rear end of the recording medium bundle has a predetermined amount of cutting length. It is a secured position. That is, the cutting amount of the recording medium bundle by the cutting unit 51 can be adjusted by changing the distance between the cutting position of the cutting unit 51 and the folding position of the additional folding unit 52.
Next, the additional folding operation by the additional folding roller 521 is started, and then the trimming operation is performed by the trimming means 51 to trim the fore edge. After the trimmer operation by the cutting means 51 is completed, the additional folding unit 52 moves in the direction of the discharge roller pair 53 in the direction of the arrow (E) shown in FIG. 5B while performing the additional folding operation by the additional folding roller 521. I do.
When the additional folding operation by the additional folding roller 521 is finished, the transport drive motor 33 that has been stopped rotates to transport the recording medium bundle toward the discharge roller pair 53, and the discharge roller pair 53 is also driven to record. The medium bundle is discharged in the direction of the arrow (F) shown in FIG.
