When the deck or the cassette is slid in, the cassette open/closed sensor turns on and, at the same time, the pickup roller starts to move down, causing the light-
blocking plate to leave the lifter sensor, driving the cassette lifter motor and, ultimately, moving up the lifter.
The lifter keeps moving up until the lifter sensor detects the surface of paper. (In the case of the deck right/left, a limiter is mounted to stop the lifter if it fails to
stop moving up.)
When the deck or cassette open button is pushed, the drive gear of the lifter becomes free to let the lifter move down on its own weight.
