1. A compact disc (CD) player, comprising playback substrates (7) and (50), a conveying roller (10), CD sensors (11) and (15), a CD stopper (8), a first trigger member (17), frame members (31) and (53), cam members (32) and (54), and moving members (9), (16) and (45), wherein the playback substrates (7) and (50) freely movably supported in a frame (1); the conveying roller (10) configured to convey a CD from an insert (4) of the frame to the playback substrate; the CD sensors (11) and (15) driven to rotate by the CD inserted into the insert; the CD stopper (8) provided with a major axis (8c) and abutting portions (8a) and (8b) disposed at both ends of the axis and configured to abut against a minor-diameter CD (A) conveyed by the conveying roller, being perpendicular to a centerline of a CD conveying path, and rotating around the axis; the first trigger member (17) rotating when the minor-diameter CD stopping at a mountable position on a turntable (5) via the CD stopper; the frame members (31) and (53) driven to move after receiving the movement of the first trigger member and the power of a motor; the cam members (32) and (54) coupled with the frame members to enable a chuck (21) to be far away from the turntable; the moving members (9), (16) and (45) receiving the rotation of the CD sensor and moving along the outside diameter of the CD; and wherein
the moving members provided with clamping portions (16c) and (45b) and abutted portions (9d), (9e) and (45a) configured to be clamped with the abutting portions; clamped portions (18b) and (54c) configured to abut against the clamping portions disposed on the cam members or an actuating member (18) coupled with the cam members at mobile terminals of the cam members; and the moving members enabling the abutting portions to stop at positions, at which the abutting portions abut against the minor-diameter CD, via the clamping connection of the abutting portions and the abutted portions, and driving the axis of the CD stopper to rotate via the abutting connection of the clamping portions and the clamped portions, so that front ends of the abutting portions can rotate towards the outside from the periphery of the minor-diameter CD.
