Abstract
An electric stapler is provided which comprises a stapler body (10) having a driving-out portion (720) and a driver (321) for driving a staple from the driving-out portion (720) into, for example, sheets of paper while reciprocating. The stapler body (10) includes a table (100) which reciprocates in conjunction with a driving mechanism by which the driver (321) is reciprocated. The sheets of paper are held between the table (100) and the driving-out portion (720) when the table (100) reciprocates. Clinchers (401, 402) are disposed on the table (100). The clinchers (401, 402) clinch the ends of the staple which is driven by the driver (321) and has passed through the sheets. After the sheets of paper are held between the table (100) and the driving-out portion (720), the driver (321) drives the staple into the sheets, and the clinchers (401, 402) are then actuated.
