Teminal Description
LCD driver serial 1/0 terminal group.
LC75852 is used.
ON/OFF control output terminal of APC amplifier for laser
output control"L”: laser “ON”
Chucking SW input terminal.
This terminal detects chucking completion of the disc.
When a disc is loaded and chucking SW is ON, “L” is input.
Control terminal of loading motor.
Disc is loaded and ejected.
