Abstract
In a stapling device capable of automatically inserting one or more staples into piled sheets discharged from an image producing device or the like to bind the sheets, a staple driver unit for inserting the staple into the sheet and a clinching unit for bending the leg parts of the staple piercing the sheets are opposed to each other astride a sheet passage and operated to perform stapling by a simple stapling drive having a single power source. By operating the staple driver unit and the clinching unit by the single power source, the precise and stable stapling operation can be carried out with exquisite timing without using a high-level controlling system.
