Abstract: A sheet processing device includes a pressing unit that includes a first pressing member and a second pressing member, the first pressing member opposing and pressing a fold of a sheet, the second pressing member nipping the fold, being positioned opposite to the first pressing member, and pressing the fold; a sheet placement unit that is provided below the pressing unit, the sheet being placed on the sheet placement unit; and a moving unit that moves a position of at least one of the first pressing member and the second pressing member of the pressing unit and causes the sheet whose fold has been pressed by the pressing unit to move to the sheet placement unit by self weight of the sheet.

Abstract: A film releasing device includes at least one transport member configured to transport a stack of a substrate and a film and to discharge the stack, a negative-pressure-generating unit provided on a discharge side of the transport member and configured to attract the film with a negative pressure generated on a surface of the film, and a communicating portion communicating with atmosphere and provided in a region of the film that is on a side facing the substrate, the region overlapping a part of a negative-pressure-generated area of the film. The film is released from the substrate in such a manner as to be guided in a direction that is different from a direction of discharge while the film is attracted to the negative-pressure-generating unit.
