Abstract
In a stapling device for sheet stacks 9 in which at least one stapling head 1 is provided whose drive 11 is actuated by a switching mechanism, the switching mechanism cooperating with a sensor sensing the thickness of the sheet stack to be stapled. The sensor has a movable sensing element in the form of a pressure member 17, 25 which, during sensing movement, presses a broadside of sheet stack 9 against an abutment 27 so that the thickness of sheet stack 9, positioned between the abutment 27 and the pressure member 17, 25, limits the path length of the sensing movement of the pressure member 17, 25.
