Abstract:
A sheet postprocessing apparatus comprising:a magazine unit including a magazine for storing staple sheets and a driver which is vertically movable relative to the magazine, each of the staple sheets being formed by connecting straight staples together in a form of a sheet; a clincher unit including a clincher holder and a driving mechanism for vertically moving the clincher holder, said clincher unit being disposed vertically opposite to said magazine unit; and a driving source for driving the driving mechanism of said clincher unit, wherein a material to be stapled is inserted between said magazine unit and said clincher unit, and the clincher holder of said clincher unit is moved closer to said magazine unit by using said driving source such that the clincher unit moves said magazine unit from a first position to a second position with the second position being further from an initial position of the clincher unit than the first position in order to make the driver relatively drive a staple of the staple sheet to pass through the material and bend.
