Punch Unit Driving Sequence
When the paper feed motor drives, the driving force is transmitted
through punch unit drive gear to the clutch gears of the punch unit.
Since the punch clutch is normally opened OFF, the driving force is
not transmitted to the driving shaft. When the punch clutch turns ON,
it is closed and unlocked. The driving force is then transmitted from
the clutch gears to the driving shaft. As the shaft turns, the rotation
of the cam causes the paper to be hole-punched. Immediately after
one turn of the shaft, the punch clutch turns OFF, and the drive shaft
stops.
