Abstract:
A disk device which conveys circular disks of different sizes and cartridge-stored disks used in cartridge-stored form, loads said disks onto a turntable and ejects said disks from said turntable, said disk device comprising:a single drive motor which is driven by insertion of said circular disk or said cartridge-stored disk; a first type disk conveying mechanism having a conveying roller which performs uptake and ejection of the circular disk by a drive force of the drive motor; a clamp mechanism which clamps said circular disk by a clamp lever which is operated from an initial position to said turntable together with uptake of said circular disk to a fixed position by the conveying roller of the first type disk conveying mechanism; a clamp lever rotation mechanism which is driven by said drive motor when the cartridge-stored disk is inserted and displaced to a position which does not impede the uptake or ejection of the cartridge-stored disk, said clamp lever rotation mechanism rotating said clamp lever back to an initial position during ejection of the cartridge-stored disk; an second type disk conveying mechanism connected to said clamp lever by a link mechanism, for performing the uptake of the cartridge-stored disk together with refuge of the clamp lever away from the turntable and for performing the ejection of said cartridge-stored disk together with return of said clamp lever to an initial position; and an second type disk placing mechanism which places the cartridge-stored disk on said turntable together with the uptake of said cartridge-stored disk to a fixed position by said second type disk conveying mechanism.
