5. Ejection Detection Mechanism (X92-3780-XX)
In order to enable reloading of a disc after it has been ejected, It is required to detect the position of the disc in the standby
condition.
The ejected disc position is detected by the "reload detect switch, which Is turned on/off by the DET lever assy.
Standby condition
When the disc is in the standby condition, the detection
sWItch Is turned ON by the disc so reloading is possible.
(Figure A)
When the disc is taken Out, the DET lever assy is separated
from the disc, and the reload detect switch is turned OFF,
thereby detecting the absence of the disc. (Figure B)
