C. Feeding Document Only into Film Cartridge
1. The SG motor mounted at the right of the chassis runs to rotate the Control cam
gear (also mounted at the right of the chassis) to its prescribed position.
2. As the Control cam gear rotates, the LF change shaft is rotated to its prescribed
position by the cam on the Control cam gear.
3. A cam is mounted on the LF motor end of the LF change shaft (at the left of the
chassis). As the LF change shaft rotates, this cam rotates the two Gear holders at
the left of the chassis, which transmit the LF motor drive as shown in the diagram.
4. As a result of steps 1 to 3 above, the drive is transmitted to the Paper feed roller
only. A document is fed into the Film cartridge by the Paper feed roller as the LF
motor rotates.
