In the following description, the whole changer block is referred to as "CDM82" and the disc

chucking mechanism block is referred to as "CDM80".

1. Ejecting the Disc

(1) Ejecting the disc in the stocker block

If you rotate the PULLEY (LOD MOTOR) on the side surface of the mechanical block after

removing the CDM82 from the set, the stocker block moves slightly forward.

(Refer to the first figure in "3-15 Arm Section" on page 20.)

Gently pull out the stocker block that has been moved slightly forward, to reveal the LOADING

MOTOR (page 112, M871). Pull out the stocker block as far as possible. Rotate, with your fingers

the PULLEY(page 112, 956) around which the loading motor belt is wound, to rotate the stocker by

90 degrees.

Press the levers beside the disc insertion slots of the respective trays to remove the discs. Pressing

the levers will make the discs pop out. Be careful not to damage the discs.

After removing the discs, reverse the above procedure. No particular adjustment of the mechanism

block is required.

(2) Ejecting the disc chucked in the CDM80

First, remove the CDM80 from the CDM82.

Slide the stocker block forward. (Refer to 3-15 on page 20.)

Rotate the PULLEY (ELV MOTOR) to move the CDM80 to the uppermost position, where the

CDM80 can be removed. (Refer to 3-16 on page 21.)
