Abstract:
A disk device which conveys circular disks of different sizes and cartridge-stored disks in cartridge-stored form, loads said disks onto a turntable and ejects said disks from said turntable, said disk device comprising:an optical pickup for reading information recorded on said circular disk; a CD feed mechanism having a feeding roller for performing the uptake and ejection of circular disks; a clamp mechanism for pressing a central section of a circular disk taken up by said CD feed mechanism from above and mounting said disk on said turntable; an MD conveying mechanism for performing the uptake of a cartridge-stored disk, mounting of said cartridge-stored disk onto said turntable, and ejection of said cartridge-stored disk from said turntable in a state where said cartridge-stored disk is inserted into said MD holder, by the movement of a conveying arm which forms a section of a link mechanism; a clamp lever refuge mechanism for refuging said clamp lever of said clamp mechanism to a position which does not interfere with the uptake and ejection of said cartridge-stored disk when said cartridge-stored disk is taken up and ejected by said MD feed mechanism; and a feed roller displacement mechanism for displacing a position of said feed roller to a position lower than an initial position when a circular disk is inserted and further towards the direction of disk insertion than said optical pickup, said mechanism performing such displacement when said circular disk taken up by said CD feed mechanism is mounted on said turntable, said feed roller mechanism returning a position of said feed roller from a position lower and further towards the direction of disk insertion than said optical pickup to an initial insertion position when said circular disk is ejected from said turntable.
