Abstract
An electric stapler has a stapling mechanism which is connected to a power source through a switch and staples a sheet stack inserted into a throat. An actuator is adapted to abut against an edge of a sheet stack at a plurality of positions along the edge of the sheet stack and to be moved by the sheet stack in response to insertion thereof to an operative position where it operates the switch to actuate the stapling mechanism. A sub-actuator is positioned in front of the actuator and is movable between an erected position where it stands into the sheet stack insertion passage to abut against a sheet stack when the sheet stack is inserted into the throat and a horizontal position where it is retracted from the sheet stack insertion passage not to abut against a sheet stack. The sub-actuator is adapted to abut against a pair of adjacent edges of a sheet stack forming a corner of the sheet stack when it is in the erected position and is movable to drive the actuator to the operative position pushed by the sheet stack as the sheet stack is further inserted into the throat.
