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.)
