2. MECHANISM DESCRIPTIONS

- Loading actions

1. When a disc is inserted, SW Arm L and R rotate. Due to the rotation of Arm L, SW1 is switched from ON to OFF and

the Load Carriage Motor starts.

2. If the disc is 12cm-disc, when it is carried to the position shown with the dotted line in the drawing, SW 3 switches

to ON due to such rotation of Arm. Then, the microcomputer judges that the disc is 12cm-disc.

3. In case of 8cm-disc, the disc cannot reach such dotted line position, and from such limitation of approach, the

microcomputer judges that the disc is 8cm-disc and simply triggers clamp actions.

(Movement of SW Arm L and R are connected together. So, if pushing force is fed to only one arm, the distance

between tow arms cannot be widened beyond the specific degree, because the coupling part is locked in such case.)

- Disc centering mechanism

1. In case of 12cm-disc, the 12cm-Disc Detection Arm rotates, and with such rotation, it raises the Centering Arms to

retreat the arms from disc's trace. The disc passes through under the arms, and at the inner part, it is centered.

2. In case of 8cm-disc, it is just centered at the position where its edge touches the front portion of the Centering Arm.
