Optical disk drive having a carrying roller that contacts a surface of an optical disk
View Patent ↗Provided is an optical disk drive including a carrying roller for carrying an optical disk in a first direction. The carrying roller includes a first roller portion and a second roller portion which are aligned in a second direction along the optical disk and orthogonal to the first direction and which are so disposed as to make contact with a surface on one side of the optical disk. An axis of the first roller portion is so inclined that a distance between the axis of the first roller portion and the one-side surface of the optical disk gradually increases toward a central portion of the carrying roller. An axis of the second roller portion is so inclined that a distance between the axis of the second roller portion and the one-side surface of the optical disk gradually increases toward the central portion.
1. An optical disk drive comprising
a carrying roller configured to carry an optical disk in a first direction;
the carrying roller including a first roller portion and a second roller portion which are aligned in a second direction along the optical disk and orthogonal to the first direction and which are so disposed as to make contact with a surface on one side of the optical disk;
an axis of the first roller portion being so inclined that a distance between the axis of the first roller portion and the one-side surface of the optical disk gradually increases from an end portion on one side of the carrying roller in the second direction toward a central portion of the carrying roller in the second direction;
an axis of the second roller portion being so inclined that a distance between the axis of the second roller portion and the one-side surface of the optical disk gradually increases from an end portion on the other side of the carrying roller in the second direction toward the central portion of the carrying roller in the second direction.
2. The optical disk drive according to claim 1 ,
wherein the first roller portion and the second roller portion are so supported that the first roller portion and the second roller portion can move independently from each other in a third direction orthogonal to both the first direction and the second direction.
3. The optical disk drive according to claim 2 ,
wherein the first roller portion is supported by a first bracket,
the second roller portion is supported by a second bracket,
the first roller portion and the second roller portion are each movable between a first position where to make contact with the optical disk for carrying the optical disk and a second position spaced from the first position, and
the first bracket and the second bracket are pressed by a common movable member so that the first roller portion and the second roller portion are moved from the first positions toward the second positions.
4. The optical disk drive according to claim 2 ,
wherein the first roller portion is supported by a first bracket,
the second roller portion is supported by a second bracket, and
one of the first bracket and the second bracket has a shutter portion for covering an insertion port for inserting the optical disk therethrough.
5. The optical disk drive according to claim 1 ,
wherein the carrying roller has a coupling shaft disposed between the first roller portion and the second roller portion so as to transmit a rotational force from one to the other of the first roller portion and the second roller portion.
6. The optical disk drive according to claim 1 ,
wherein the first roller portion and the second roller portion each include a cylindrical core portion and a cushion portion formed at an outer peripheral surface of the core portion, and
the core portion and the cushion portion are formed by two-color molding of resin.
