Abstract:
A disk device comprising:a conveying roller for conveying circular disks of differing sizes; a disk guiding section facing said conveying roller and guiding said disk; a disk selection mechanism having projections which are provided in proximity with said conveying roller, said projections being disposed at predetermined positions of said disk guiding section for selectively abutting with a surface of the disk inserted between said conveying roller and said disk guiding section depending on an outer radius of the disk, thereby changing an angle of said disk in the conveying direction depending on the outer radius wherein a large radius disk is angled away from the disk selection mechanism and wherein the angle of a disk of a small radius is maintained or changed by the projections based on the position the small radius disk is inserted in the disk guiding section; and a positional determination mechanism for positioning the disk, an angle of which is regulated by said disk selection mechanism, at respective predetermined positions preset in accordance with the outer radius of said disk.
