Further, since the sheet bundle moving means can be positioned and stopped at a position facing the plurality of aligning trays,
Since it is not necessary to move the alignment tray storing the sheet bundle or the sheet bundle itself until the binding of the sheet bundle is completed and the sheet bundle is handled, it is possible to reliably prevent the alignment disorder of the sheet bundle.

Further, since the bookbinding apparatus is provided with the sheet automatic sheet feeder capable of automatically feeding the sheet bundle on which the image has been formed so that it can be carried into the alignment tray, the online apparatus connected to the image forming apparatus or the like can be used. Even in the bookbinding device, the bookbinding device can be used independently, and the bookbinding device can be used online.
You can bind books both offline.
