A saddle stitching binding device includes an additional folding roller unit that presses a fold line portion of a folded sheet bundle and performs additional folding, and a unit movement mechanism that causes the additional folding roller unit to reciprocate in the width direction of the sheet bundle. The saddle stitching binding device further includes a sheet supporting device that is located on a movement path of the additional folding roller unit and supports the lower surface side of the sheet bundle when the sheet bundle after pressed is conveyed to the downstream side. In the saddle stitching binding device, a supporting position at which the sheet supporting device supports the sheet bundle and a retreat position at which the sheet supporting device permits the additional folding roller unit to move are set to the sheet supporting device.

A sheet processing device includes a sheet processing unit that is moved to perform sheet processing on a sheet; a sheet-processing moving unit that moves the sheet processing unit; a drive-mode determining unit that determines a drive mode of the sheet-processing moving unit; and a drive control unit that drives the sheet-processing moving unit in accordance with the drive mode. The drive-mode determining unit determines the drive mode such that the sheet processing unit is moved at combination acceleration that is a combination of first acceleration and second acceleration with a shift of time that is determined based on the cycle of the natural vibration that occurs during acceleration of the sheet processing unit.

According to an embodiment, an ADF that feeds and conveys original document sheets one sheet by one sheet from a tray unit to a read position on a document glass by motive power from a driving motor includes: an opening/closing unit operable to open and close relative to the document glass; an open/close detection sensor that detects an open/closed state of the opening/closing unit; a first interlock switch, which is arranged between a power source and the driving motor, that is on when the opening/closing unit is closed, and vice versa; and a control circuit that determines the open/closed state of the opening/closing unit based on detection outputs of the first interlock switch and the open/close detection sensor. The control circuit determines that the opening/closing unit is in the closed state when the first interlock switch is on and the open/close detection sensor is detecting the closed state.
