Abstract
The disclosed stapler has a manual actuator that is depressed to force a staple magazine against papers on an anvil, charging a leaf spring that carries a staple driver. A stop arrests the staple driver during this operation of the actuator. The staple driver is released by the actuator near the end of the actuator's stroke, to drive a staple through the paper and to cause the anvil to set the staple's legs. The manual actuator releases the staple driver for spring-impelled operation by deflecting the staple driver off the stop.
