These components operate as follows:
i) Clutch gear B is driven by the paper feed gear.
ii) When the "paper feed signal" is given, the rotation of clutch gear B is conveyed to the
paper feed cam through the paper feed Cam control clutch.
iii) The paper feed cam rotates and depresses the up -down arm.
iv) The pickup arm pivot shaft is rotated by the up-down control arm in the direction
shown in Fig. 4-59 because the shaft is secured to the arm by a setscrew.
v) At the same time the up-down actuator on the pickup arm pivot shaft is turned in the
the same direction with the shaft.
vi) The up-down actuation lever turns and raises up the pickup arm brace.
