5.6 SECOND FEED ROLLER MECHANISM

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 second 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 stopper. 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.
