Zusammenfassung: | To prevent misalignment when performing a predetermined post-processing out of multiple post-processing procedures.SOLUTION: A post-processing device is configured such that it is possible to select either a bookbinding process mode (first mode) in which a saddle stitch process (first post process) is performed on a sheet P and then a center folding process (second post process) is performed, or a center folding process mode (second mode) in which a center folding process is performed on the sheet P without the saddle stitch process. And when the bookbinding process mode is selected, before the sheet P to be saddle stitched is received, the position of aligning devices 84, 85 in the transport direction is adjusted by a moving mechanism 110, and when the center folding process mode is selected, the positions of the aligning devices 84, 85 in the transport direction are adjusted by the moving mechanism 110 before the sheet P to be center-folded is received.SELECTED DRAWING: Figure 6
【課題】複数の後処理のうち所定の後処理をおこなう場合に、揃え不良が生じにくくする。【解決手段】シートPに対して中綴じ処理(第1の後処理)を施した後に中折り処理(第2の後処理)を施す製本処理モード(第1モード)と、シートPに対して中綴じ処理を施さずに中折り処理を施す中折り処理モード(第2モード)と、のうちいずれかを選択可能に構成されている。そして、製本処理モードが選択された場合には、中綴じ処理の対象となるシートPが受入れられる前に移動機構110によって揃え装置84、85の前記搬送方向の位置を調整し、中折り処理モードが選択された場合には、中折り処理の対象となるシートPが受入れられる前に移動機構110によって揃え装置84、85の搬送方向の位置を調整している。【選択図】図6 |
