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.

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.
