There is the motor
above the big gear.
The disc clamp is done
by the arm movement.
1"!3
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.
The slider travels by
the turning force of
the big gear. The force
is linked to the holder.
This holder clamps
and loads the disc.
<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.

How to Assemble Mechanism.
1. Remove the lever(Q) with the spring (@).
2. Slide the actuator assy(_)+®) to the
fully frontward.
3. Set the gear(Q) to meet with the mark of
its and the actuator assy(_+®).
4 Set the guide(Q_) to meet the mark of its
and the gear(@).
5. Load the lever(_) with the spring (@)
to the guide(@) after sliding the actuator
assy(_+®) slightly backwards.
