Abstract:
1. A sheet processing device comprising: a stacking unit that is used to stack a bundle of sheets that are placed upon each other with first edge portions of the sheets being aligned with each other; a first binding unit that binds the first edge portions of the bundle of sheets stacked upon the stacking unit; a second binding unit that is provided integrally with the first binding unit in a direction along the first edge portions of the bundle of sheets stacked upon the stacking unit, the second binding unit binding the first edge portions by a binding method differing from a binding method of the first binding unit and the second binding unit being a stapleless binding unit; and an angle changing mechanism that is capable of changing an angle of the first binding unit with respect to the bundle of sheets when binding the first edge portions with the first binding unit, wherein the angle changing mechanism is capable of changing an angle of the first binding unit with respect to the first edge portions so that the angle of the first binding unit with respect to the first edge portions when the first binding unit binds a corner of each sheet is different from that when the first binding unit binds a portion of each sheet other than the corner, and wherein the first binding unit and the second binding unit are connected to each other so that an angle between the first binding unit and the second binding unit is changeable, and wherein the angle changing mechanism rotates the first binding unit to change the angle of the first binding unit with respect to the bundle of sheets while maintaining the connection between the first binding unit and the second binding unit.
