Abstract: The present invention provides a disk reproducing device with a disk clamp mechanism capable of securely grasping a disk and making the device smaller. An inclined portion and a clamper supporting annular portion are formed in a clamper support plate, and a clamper is mounted in an opening formed in the inner circumference of the damper supporting annular portion. Thereby, even if an upper brim portion is located in the middle of the inclined portion when a disk is removed, the upper brim portion slides down along the inclined portion so that the clamper is placed on the damper supporting annular portion. When the disk is again inserted and rotated, the disk can be securely grasped between the clamper and a turntable without a displacement of the clamper. Further, the inclined portion can improve the strength of the damper supporting annular portion, thereby making it possible to thin the clamper supporting annular portion.
