Abstract
A compact, electric, spring energized desktop stapler having a unitized housing providing both an external movable enclosure and a support frame for internal parts is disclosed. The internal power train is preferably elongated with the motor at the rear, a gear set toward the center, and low profile lever and power spring assembly at the front. The lever engages a striker with a normal upper rest position where the power spring is deflected and energized. A cam roller mounted to a final gear holds down the rear of the lever until the system is activated when the final gear rotates and the cam roller rolls off the end of the lever. In the unitized body, the base is pivotally attached to the body at the rear. A base lever selectively links to a cam roller or equivalent structure to move the body downward toward the base during a cycle.
