摘要 PURPOSE:To contrive to miniaturize the entire device by using a small spiral cam member so as to move a support member supporting freely turnably a depressing member. CONSTITUTION:A support member 38 supporting freely turnably a pressing member 52 provided freely movably in a plane nearly perpendicularly to a disk support face of a turntable 37 to press an information recording disk 22 toward a disk support face and a drive means moving the support member 38 are included and the drive means consists of a cam member 53 provided freely turnably around the rotary center shaft nearly perpendicularly to the disk support face, formed around the rotary center shaft and having a spiral cam in slide contact with a part of the support member 38 and a torque provision means giving a torque to the cam member 53.
