MECHANISM OPERATION DESCRIPTION
There is the motor
above the big gear.
The pin drawn the dot
line travels with the big
gear to the arm.
The turning direction
of the shortest route
is choosed by the
rotary motor.
<DISC LOADING>
The Holder M(Stocker Rotary)
stops to turn at the choosed
disc number.The turning force
of the loading motor(LM) is to
carry the disc to the holder
and the disc is clamped.
This holder clamps
and loads the disc.
The slider travels by
the turning force of
the big gear.The force
is linked to the holder.
The disc clamp is done
by the arm movement.
