2. MECHANISM DESCRIPTIONS

- Loading actions

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

When SW1 is switched from ON to OFF, the Load Carriage Motor is started and the rubber roller rotates.

2. If the disc is a 12cm-disc, SW3 is turned ON with SW Arm, and the microcomputer determines that the disc is a

12cm-disc.

3. In case of an 8cm-disc, SW3 is not turned ON, a clamp action is triggered, and the microcomputer determines that the

disc is an 8cm-disc.

(The left and right of SW Arm are coupled, and when only one side is pushed, the coupled joint will lock, and the arms

will not open more than a certain width (SW3 will not be turned ON).)
