CHAPTER 5 PICK-UP/FEEDING SYSTEM
w When the lift arm lowers, the pick-up roller shaft moves down, pushing the lift-up
releasing arm to free the lift-up cam. At the same time, the lift arm is locked to the
pick-up roller shaft fixing arm, stopping the pick-up roller shaft at a specific position.
e When the lift-up cam is freed, the lift-up cam starts to rotate so that the lift-up arm
pushes up the lifter gear by a distance equivalent to a single tooth. These opera-
tions are repeated to move up the cassette holding plate.
