CHAPTER 5 PICK-UP/FEEDING SYSTEM
5-11 P
2.2 Lifter Movement
2.2.1 Outline
When the deck or the cassette is pushed in, the cassette open/closed sensor turns on and,
at the same time, the pickup roller moves down. The condition causes the light-blocking
plate to move away from the lifter sensor, consequently turning on the cassette lifter motor
to move up the lifter.
The lifter keeps moving up unitil the lifter sensor detects the surface of paper. In the case
of the right/left deck, a limiter is mounted to prevent the lifter from moving farther up than
the lifter sensor.
When the open button of the deck or the cassette is pressed, the drive transmission gear of
the lifter becomes free, allowing the lifter to move down on its own weight.
