The entrance guide mylar [A] holds the originals against the pick-up roller [B]
to facilitate paper feed.
The pressure release cam [C] lobe pushes the lever [D] upward to release
the pressure mylar [E]. This makes it easier to set the originals.
During paper feed, the cam rotates and the pressure mylar pushes down the
entrance guide mylar by the force of the return spring.
The pressure mylar lever stops at the stopper [F] to prevent over pressure
being applied.
A heart-shaped cam [G] is installed on the pick-up roller shaft. When the cam
follower [H] drops into the depressed portion of the heart- shaped cam, the
pick-up roller stops. At this time, the flat surface of the pick-up rollers is level
with the original table.
