The Holder M(Stocker Rotary) stops to turn at the choosed disc number. The turning force of the loading motor(LM) is to carry

10、the disc to the holder and the disc is clamped. This holder clamps and loads the disc. The slider travels by the turning force of the big gear. The force is linked to the holder. The disc clamp is done by the arm movement. CD-223M/DPF-J3010(K) COVER( 98.4.25 11:00 AM yW 6 RadioFans.CN 收音机爱 好者资料库 CD-
