DOPPELEINLEGESPERRE FUER EINEN PLATTENSPIELER

摘要

A disc player is disclosed which comprises a casing (1) having a disc insertion opening (2), a turntable (29) driven by a spindle motor (30), and a clamper arm (32) operating means (33) for operating the clamper arm in cooperation with the turntable. A centering mechanism (12) guides a disc (106) from the disc inserting opening onto the turntable, the centering mechanism including a pair of centering arms (13, 14) each having contact portions (18, 19) which come into contact with the circumferential edge of the disc. The centering arms are pivotally movable at a predetermined distance in the disc inserting opening. A detecting lever (41, 42) detects when the disc is laid on the turntable, and a double insertion preventing lock linkage (43, 58) prevents another disc from being inserted into the casing through the disc inserting opening when the first-mentioned disc is already located on the turntable, by latching the disc centering mechanism. <IMAGE>
