1. Laser Interlock Mechanism
The position of the switch (S601) for detecting loading
completion is detected by the system microprocessor, and
the design prevents laser diode oscillation when the
switch is not in LPS1 terminal side (when the mechanism
is not clamped and LPS1 signal is high level.) Thus, the
interlock will no longer function if the switch is deliberately
set to LPS1 terminal side. (if LPS1 signal is low level).
In the test mode* the interlock mechanism will not
function.
Laser diode oscillation will continue, if pin 19 or 20 of
µPC2510 (IC50) on the MAIN board assy connected to
high level, or else the terminais of Q50 or Q51 are shorted
to each other .
2. When the cover is opened, close viewing of the objective
lens with the naked eye will cause exposure to a Class 1
laser beam.
