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.
Claims19
A disc device comprising:
- a rotatable table including a disc-receiving portion for receiving a surface of a disc, a protrusion for insertion into a center aperture of the disc, and a disc-holding means for holding a disc on the rotatable table by elastically applying pressure to an inner peripheral edge surrounding the center aperture of the disc;
- a pressing member opposing the disc-receiving portion of the rotatable table;
- and
- a pressing driving means for driving at least one of the rotatable table and the pressing member in a direction in which the rotatable table and the pressing member move towards each other in a manner that causes the disc-holding means to engage the inner peripheral edge of the disc.
A disc device comprising:
- a rotatable table including a disc-receiving portion for receiving a surface of a disc, a protrusion for insertion into a center aperture of the disc, and a disc-holding means for elastically applying pressure to an inner peripheral edge surrounding the center aperture of the disc;
- a plate member opposing the disc-receiving portion of the rotatable table;
- a driving chassis for supporting the rotatable table, the driving chassis being movable relative to the plate member;
- and
- a pressing driving means for driving the rotatable table toward the plate member in a manner that causes the disc-holding means to engage the inner peripheral edge of the disc;
- wherein a disc-passage space is formed between the plate member and the rotatable table when the plate member and the rotatable table are separated from each other;
- and
- wherein the plate member functions as a guide plate for the disc that passes into the passage space.

- a pressing member opposing the disc-receiving portion of the rotatable table;
- a pressing member support shaft rotatably supporting the pressing member;
- and
- a pressing driving means for driving the pressing member toward the rotatable table in a manner that causes the disc-holding means to engage the inner peripheral edge of the disc.
