Abstract
A disk device includes a traverse chassis (20) that supports a turn table (30) or the like, and a main chassis (10) that rotatably supports the traverse chassis (10). The traverse chassis (20) has two coaxial bosses (21a, 21b). The main chassis (10) has two boss supporting portions (1a, 1b) that support the bosses (21a, 21b) of the traverse chassis (20). Protrusions (22a, 22b) are formed on the tips of the bosses (21a, 21b). The protrusions (22a, 22b) abut against the boss supporting portions (1a, 1b), so as to prevent the deformation of the boss supporting portions (1a, 1b) in the directions away from each other, with the result that the dropping of the traverse chassis (20) from the main chassis (10) is prevented.
Claims5
A disk device comprising:
- a traverse unit including a turn table that holds and rotates a disk medium, an optical pickup that performs at least one of writing and reading of information on said disk medium, and a traverse chassis that supports them;
- a carrier that carries said disk medium between a loading position and an unloading position;
- and
- a main chassis supporting said traverse unit so that said traverse unit is capable of rotating, allowing said traverse unit to move toward and away from said disk medium,
- wherein said traverse chassis has a pair of coaxial rotation shafts for said rotating, and said main chassis has a pair of supporting portions respectively supporting said rotation shafts, and
- wherein said supporting portions include groove portions that open in a direction substantially parallel to the carrying direction of said disk medium carried by said word carrier, and resiliently deformable position-regulating members that regulate the positions of said rotation shafts so as to prevent said rotation shafts from being dropped out of said groove portions.
