ABSTRACT:
In a stapling machine, an ejector blade can be moved to eject a staple through a staple ejection slot towards an anvil adapted to clinch the ends of the arms of the staple. The staple ejector blade is moved by an actuator element. A toggle is provided which maintains the actuator element in a first position until a predetermined force has been applied to the actuator element. The toggle then releases the actuator element permitting the actuator element to move the ejector blade to eject a staple through the staple ejection slot towards the anvil.
