Claims

[Scope of utility model registration request]

A disk storage casing is provided with a disk mounting plate on which a disc-shaped information recording medium is placed, and is provided with a driven means, a guide means for guiding the disk storage casing, and a drive means for driving the driven means. A drive mechanism for horizontally moving the storage case, a lowering means for lowering the disk mounting plate, a disk pressing means for pressing the information recording medium, and a turntable that is driven to rotate with the disk placed thereon. and a disc-shaped information recording medium reproducing apparatus comprising a drive means for driving the drive mechanism and operating the lowering means and the disk pressing means, wherein a first drive means is configured to lock the lowering means and prevent the lowering operation. a second locking portion that locks on the disk pressing means to prevent the pressing operation; and an operating portion that abuts the guide means, and the disk storage case is located at a predetermined position. When the disc is in a position other than the above, the first locking part locks with the lowering means, the second locking part locks with the disk pressing means, and the disk storage case is in a predetermined position. In a reproducing apparatus for a disk-shaped information recording medium, the operating part is configured to be locked to the guide means and the first and second locking parts are unlocked at some time. Safety device.
