Claims

[Scope of utility model registration request] ■ Recording disc storage that stores the recording disc in an upright position.
a recording disk player having a turntable disposed below the storage section and rotatable in a vertical plane; It is arranged to be freely rotatable in the plane, and during playback, the recording disk is placed on the supporting portion to support it at the upper limit of rotation, and in this supported state, the recording disk rotates downward with downward movement due to its own weight. An automatic recording disk reproducing device comprising: a disk carrying arm that supplies the recording disk to the turntable of the playback machine, and rotates upward to return the recording disk to the storage section when playback is finished. 2. The storage section further includes a stopper that is movable in conjunction with the disk carrying arm and normally locks the recording disk in the storage position, and the disk carrying arm is rotated upward to pick up the recording disk. When the movement limit is reached, when the support section lifts the recording disk to an upper position slightly above the storage position, the stopper escapes and is displaced to allow the recording disk to move downward, and the arm moves toward the recording disk. When the upper rotation limit for feeding the disk is reached, and when the recording disk is moved past the storage position to the upper position, the stopper is displaced back and locks the recording disk in the storage position. An automatic recording disc reproducing device according to claim 1 of the utility model registration claim, which is configured to enable the following.
