Claims

[Claims for Utility Model Registration] (1) An information recording medium in which a disk carrier is movably disposed between a disk storage section and an information recording/reproduction processing section to process information on a disk, which is a disc-shaped information recording medium. In the automatic selection processing device, the frame of the disk carrier rotatably supports the shaft of the disk holder that holds the edge of the disk, and a sliding body is attached to the frame, and the disk holder is moved forward and backward in the axial direction on this sliding body. An information recording medium automatic selection and processing device characterized in that a cam for moving the disk holder is provided, and a rack gear meshed with a pinion gear fitted to the shaft of the disk holder is floatingly supported on a sliding body. (2) The cam of the sliding body retracts the disk holder to a position outside the edge of the disk at both end positions of the sliding stroke, and the rack gear moves the frame body in a range other than both end positions of the sliding stroke of the sliding body. The movement range is regulated by a stopper provided at the disk holder, and the distance from one moving end to the other moving end is 1
The information recording medium automatic selection processing device according to claim 1, characterized in that the information recording medium automatic selection processing device is set to correspond to rotation of 80 degrees.
