The stapler motor (4) drives both the driver plate (12) and homing plates (13) toward the
clincher. The driver plate and homing plates separate and feed the staples to the clincher
(2) that performs the stapling.
The pressure of the plunger (11) feeds the next staple for firing. A staple supply pawl below
the staple sheet moves to the front and back to assist in staple supply. The plunger feeds
only one staple at a time, but the staple supply pawl can feed up to 10 staples.
