Document Type and Number:
Japanese Patent JP3554632
Kind Code:
B2
Abstract:
An electric stapler (1) has a stapling mechanism which is connected to a power source through a switch and staples a sheet stack (3) inserted into a throat (4). An actuator (7) is adapted to abut against an edge of a sheet stack (3) at a plurality of positions along the edge of the sheet stack (3) and to be moved by the sheet stack (3) in response to insertion thereof to an operative position where it operates the switch (11) to actuate the stapling mechanism. A sub-actuator (20) is positioned in front of the actuator (7) and is movable between an erected position where it stands into the sheet stack insertion passage to abut against a sheet stack (3) when the sheet stack (3) is inserted into the throat (4) and a horizontal position where it is retracted from the sheet stack insertion passage not to abut against a sheet stack (3). The sub-actuator (20) is adapted to abut against a pair of adjacent edges (3b,3c) of a sheet stack forming a corner of the sheet stack (3) when it is in the erected position and is movable to drive the actuator (7) to said operative position pushed by the sheet stack (3) as the sheet stack (3) is further inserted into the throat (4).
