Abstract
A disc device in which, when a driving unit including a self-chucking-type rotatable table is moving towards the front, a disc is transported by a transporting roller, and is sent between the rotatable table and a guiding plate. At this position, a driving unit moves upward, causing the disc to be sandwiched between the rotatable table and the guiding plate, so that the disc is clamped to the rotatable table. Thereafter, the driving unit moves downward, and moves further towards the back side of a housing in order for the disc to be drawn into the housing. A disc device using a self-chucking-type rotatable table requires a complicated mechanism for pushing a disc against the rotatable table, so that it is difficult to reduce the size of the disc device.
