[D] [B]
The lower second feed roller [A] is driven by the sector gear [B] and the
gear [C]. When the paper feed solenoid [D] turns on, the link [E] combined
with the paper feed roller sector stopper [F] is pulled and the second feed
roller sector stopper [G] turns counterclockwise.
When the bearing [H] of the sector gear comes to the top of the lower sec-
ond feed roller cam [I], the stopper [G] is released from the sector gear [B]
as a clearance is formed between the pin of the sector gear and the stop-
per. Therefore, the bearing of the sector gear moves along the second feed
roller cam face.
When turning the gear [C] counterclockwise, its rotation is not transmitted to
the lower second feed roller due to the one-way clutch bearing press-fit into
the gear [C].
When the bearing [H] of the sector gear moves up from the bottom of the
second feed roller cam [I], the sector gear turns counterclockwise and gear
[C] turns clockwise. As the rotation of the gear [C] is transmitted to the
lower second feed roller, the lower second feed roller turns clockwise to
feed the paper to the drum section.
