OPTICAL DISK DEVICE

PROBLEM TO BE SOLVED: To contrive the extension of the applicable range for various kinds of terminal equipments in the manner of thinning a device by optimally designing a clamper mechanism in an optical disk device utilizing a drawer system. SOLUTION: Inside the main body part capable of loading/unloading a tray mounted with the disk 101, the clamper 104 and a disk drive device 102 are respectively furnished at the position corresponding to the upper and lower sndes of the disk 101, and when the tray is drawn out from the main body part, the clamper 104 is ascended and set to the position retreated from the disk 101, and also the disk 101 is put in no relation with the disk drive device 102, and when the tray is housed, by means of descending the clamper 104 linked therewith, the disk 101 is made to be restrictive to the disk drive device 102.
