Normally, the upper second feed roller [A] is not in contact with the lower
second feed roller [B]. When the second feed roller sector gear [C] is moved,
the upper second feed roller moves against the lower second feed roller to
feed paper to the drum section.
When the sector gear [C] turns clockwise, the bearing of the lever [D] moves
down from the top of the cam [E] mounted behind the sector gear, and the
lever [D] and the upper roller shaft [F] turn clockwise.
As the upper roller shaft [F] is an eccentric shaft, the upper second feed roller
[B] contacts the lower second feed roller and the upper second feed roller is
turned by the friction of the lower second feed roller. Springs [G] apply
tension to both the right and left sides of the upper second feed roller.
