The turning forceof the loading motor(LM) is tocarry the disc to the holderand the disc is clamped.This holder clampsand loads the disc.The slider travels bythe turning force ofthe big gear. The forceis linked to the holder.The disc clamp is doneby the arm movement.CD-223M/DPF-J3010(K) COVER( 98.4.25 11:00 AM yW 6CD-223M/224M/DPF-J3010/J50104DISASSEMBLY FOR REPAIR: Ref.
