An electric stapler is provided. In this electric stapler, a driver arm is made to oscillate by making a toggle link mechanism operate by a connecting rod that performs a crank operation by a driving gear driven to rotate by a motor. A staple is put into sheets of paper by means of a driver provided at a top end of the driver arm by downward movement of the driver arm. A clinch arm is made to oscillate by a cam provided in the driving gear. Both legs of the staple penetrating through the sheets of paper are clinched by means of a clincher by upward turning of the clinch arm caused by a paper-thickness adjusting spring provided between the clinch arm and the toggle link mechanism. Due to this structure, driving load can be reduced and formation precision of each component does not affect clinching precision directly.
