摘要:
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.

A sheet processing apparatus includes: a folding unit that folds a sheet bundle; a pressing unit that presses a fold part of the sheet bundle, which has been folded by the folding unit, in a thickness direction of the sheet bundle to enhance folding of the fold part; and a moving unit that advances and returns the pressing unit in a width direction of the sheet bundle. The pressing unit starts pressing from a predetermined position in the width direction of the sheet bundle during advancing movement, and releases pressing after going past one end of the sheet bundle. The pressing unit starts pressing from the predetermined position during return movement and goes past the other end of the sheet bundle.

There are provided bookbinding apparatuses that wrap a bundle of sheets with a cover and form back corners, and have a detecting unit for detecting a wave amount of a bundle of sheets. A type of such an apparatus includes a controller to control a time period to form back corners, based on a result of detection by the detecting unit. Another type of such an apparatus includes a controller to control a pressure applied to form back corners, based on a result of detection by the detecting unit. Still another type of such an apparatus includes a controller to control a time period and pressure applied to form back corners, based on a result of detection by the detecting unit.
