Abstract
The invention aims to reduce the size of a disk clamp mechanism to be built into a disk player. The clamp mechanism comprises: a disk clamp portion formed integrally with a turntable; a clamper; and a clamper holder for holding the clamper via a clamper mounting shaft adapted to hold the clamper in rotatable fashion, wherein a flange portion provided at an end of the clamper mounting shaft is placed within a space formed inside the clamper. The clamper comprises a peripheral portion and a chamber portion in which the space is formed, and the disk clamp portion has a recessed groove portion engageable with the chamber portion, the structure being such that, when the disk is clamped, the end portion of the chamber portion is accommodated into the disk clamp portion, thus achieving a size reduction by reducing the height in a direction perpendicular to the disk.
