Abstract:
A stapler (1) is provided with a frame (3) and a head assembly (5) pivotally disposed in the frame (3) between a first open position and a second clamped position. These operative elements include a staple driving mechanism (33), a motor (83) fixed to the head assembly (5), a cam member (105) connected to the motor (83) and rotated thereby. The cam member (105) contains at least three surfaces that simultaneously form and drive staples, pivot the head assembly (5) in the frame (3), and actuate a microswitch (88) controlling power to the motor (83). The cam member (105) cooperates with a first bar (121) disposed between the frame (3) and a spring assembly (129) to permit the first bar (121) to flex to accommodate varying thicknesses or amounts of paper to be stapled.
