Claims

[Scope of utility model registration request]

a retraction mechanism that pulls a desired tray with a disk-shaped recording medium of a predetermined size placed in a recording medium placement recess around the opening from a disk introduction part to a position above the turntable along a guide body; When the disc-type recording medium is pulled to an upper position, the guide body is lowered and the disc-type recording medium is placed on the turntable, and then
a guide body lowering mechanism that separates the tray from the disk-type recording medium; a clamper that presses the disk-type recording medium placed on the turntable against the turntable; and the retraction mechanism;
In a disk-type recording medium loading device that includes a guide body lowering mechanism and a drive mechanism that operates a clamper at a predetermined timing, the tray includes a plurality of types with different sizes of the recording medium mounting recesses, and the guide body a detachment prevention member located above the recording medium placement recess of the minimum size to prevent the recording medium from coming off the tray; and a spring member that elastically presses the detachment prevention member against the guide body. and a separating member provided in the drive mechanism to separate the detachment prevention member from the guide body against the elastic force of the spring member before the tray is separated from the disk-type recording medium. Disc-type recording medium loading device with special features.
