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.

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.

How to Assemble Mechanism.

1. Remove the lever(ª) with the spring ( ).

2. Slide the actuator assy(1+9) to the fully frontward.

3. Set the gear(•) to meet with the mark of its and the actuator assy(1+9).

4. Set the guide(≠) to meet the mark of its and the gear(•).

5. Load the lever(ª) with the spring ( ) to the guide(≠) after sliding the actuator assy(1+9) slightly backwards.
