Abstract:
1. A disk device, having a case and an insertion slot formed in a front of said case, for disk loading and disk unloading of a disk of any one of two types different in a diameter, comprising: a chuck head, disposed in a middle of said case, for chucking and rotating said disk loaded in a chuck position; plural arms for contacting a peripheral edge of said disk to guide said disk, said arms guiding said disk toward said chuck position for said disk loading upon partial entry of said disk in said case though said insertion slot, said arms guiding said disk for said disk unloading from said chuck position toward an ejection position where said disk partially protrudes through said insertion slot to appear externally; a disk support arm, movable pivotally, for supporting said peripheral edge of said disk, said disk support arm being set in a ready position for said disk loading, for receiving said peripheral edge of said disk entered through said insertion slot, said disk support arm being shifted back with said disk when said disk moves to said chuck position, wherein said disk support arm, upon completion of said disk loading, is kept in a separate position away from said peripheral edge of said disk in said chuck position, and is then shifted from said separate position to press and move said disk toward said ejection position and further shifted to an advance position during said disk unloading; and an arm driving component for pivotally shifting said disk support arm and said arms, said arm driving component being actuated when said disk support arm shifts back from said ready position for said disk loading, for shifting said disk support arm to said separate position pivotally, wherein said arm driving component is actuated for said disk unloading, for shifting said disk support arm pivotally from said separate position to said advance position, and for shifting back said disk support arm from said advance position to said ready position that is offset toward said chuck head by predetermined distance.
