Claims

[Claims for Utility Model Registration] (1) Raise or lower the clamp member with respect to the turntable, load the disk onto the turntable with the clamp member in the raised position, and load the disc on the turntable with the clamp member in the lowered position. In the disc clamping mechanism of the disc playback device, the clamp member and the turntable cooperate to clamp the disc to the turntable, in which a clamp holder that pulls up the clamp member is moved up and down using a vertical axis provided on the chassis as a guide. A guide shaft is provided on the arm part hanging from the clamp holder in a horizontal direction and in a direction perpendicular to the loading direction, and oblique cam grooves are provided on the upper and lower sides with which the guide shaft engages. A disk clamp mechanism for a disk playback device, characterized in that a cam member is provided to be slidable in the loading direction, and the clamp holder is moved to a raised or lowered position by sliding the cam member. (2) A disk clamp mechanism for a disk playback device according to claim 1, wherein the clamp member has approximately the same diameter as the disk. (3) The disc playback device according to claim 1 or 2, wherein the cam member is drivingly connected to a clamp motor, and the cam member is moved by driving the clamp motor. Disc clamp mechanism.
