The invention relates to an optical disk drive, and in particular to an optical disk drive with a clamp holder.
The conventional optical disk drive has a complicated inner structure, a great number of components, large volume, and low reliability, thus an optical disk drive capable of ameliorating the described disadvantages is desirable.
The invention discloses an optical disk drive. The optical disk drive for operating an optical disk which is bi-directionally transported along a center axis of the optical disk drive includes a shield, a tray and a holder. The tray is movably connected to the shield. The holder pivots on the tray to form a cantilever with a free end. A space is defined between the free end and the center axis, and the optical disk is clamped between the tray and the holder.
The optical disk drive may further comprise a pickup mechanism connected to the shield, moving along the center axis with respect to the tray and the holder, passing through the space.
The holder may comprise a shaft pivoted on the tray. The tray may comprise a connection portion projecting upward therefrom. The shaft of the holder pivots on the connection portion.
The optical disk drive may further comprise a resilient member disposed between the tray and the shaft, providing a force to the holder to secure the optical disk in place. The resilient member may comprise a torsion spring.
The optical disk drive may further comprise a protrusion protruding toward the tray. The holder may comprise an actuating portion. When the tray moves to a position with respect to the shield, the protrusion abuts the actuating portion, and the holder rotates via the shaft, releasing the optical disk.
The optical disk drive may further comprise a damper disposed on the tray, and the optical disk is clamped between the holder and the damper.
The holder may be parallel to a surface of the tray and project toward the center axis.
Accordingly, an extension direction of the holder may be perpendicular to the center axis.
The invention further discloses an optical disk drive. The optical disk drive for operating an optical disk which is bi-directionally transported along a center axis of the optical disk drive comprises a shield, a tray, and two holders. The tray is connected to the shield and movable between a first position and a second position. The holders are symmetrically disposed on the tray and project toward the center axis. The optical disk is clamped between the tray and the holders.
The holders may be parallel to the tray. Each holder is a cantilever with a free end, and a space is defined between the free ends.
The optical disk drive may further comprise a pickup mechanism connected to the shield, moving along the center axis with respect to the tray and the holders, passing through the space.
Each holder may comprise a shaft pivoted on the tray. The tray may comprise two connection portions symmetrically arranged according to the center axis and projecting upward from a surface of the tray. The shafts of the holders are pivoted on the connection portions.
The optical disk drive may further comprise two resilient members disposed between the tray and the shafts, providing a force to the holders to secure the optical disk in place. The resilient members may be torsion springs.
The optical disk drive may further comprise two protrusions protruding toward the tray. Each holder may comprise an actuating portion. When the tray moves to the second position, the protrusions abut the actuating portions, and the holders rotate via the shafts, releasing the optical disk.
The optical disk drive may further comprise two dampers disposed on the tray, and the optical disk is clamped between the holders and the dampers.
Accordingly, an extension direction of the holders may be perpendicular to the center axis.
The invention can be more fully understood by reading the subsequent detailed description in conjunction with the examples and references made to the accompanying drawings, wherein:
When the tray 22 locates at the second position II, the center hole 101 of the optical disk 10 is aligned with the spindle 241 of the pickup mechanism 24, and the holder 23 release the optical disk 10. Thereafter, the optical disk drive may read and/or write information on the optical disk 10.
The resilient members 25 (such as a torsion spring) are respectively and symmetrically disposed on the posts 224 of the tray 22 with respect to the center axis C. One end of the resilient member 25 abuts the shaft 231 of the holder 23, and the other end abuts the tray 22 so that the resilient members 25 provide force on the holders 23 to clamp the optical disk 10.
When ejecting the optical disk, the driving mechanism drives the tray 22 to move in direction B (along the center axis C) to the first position I. Meanwhile, the tray 22 starts moving, the actuating portions 232 separate from the protrusions 242, and the holders 23 then rotate toward the tray 22 due to force provided by the resilient member 25 to again clamp the optical disk. Finally, the tray 22 moves back to the first position I as shown in
As mentioned, the structure of the optical disk drive of the invention is simpler, has fewer components, and reduced size. The tray, the holder and the resilient member are assembled without screws. The space is defined between the free end of the holder and the center axis, and the thickness of the tray is reduced. Thus, the tray, the holder and the optical disk are movable between the first position and the second position without interference with the pickup mechanism. In other words, the optical disk drive of the invention does not move down the tray and thus prevents interference between the tray, the holder and the pickup mechanism.
While the invention has been described by way of example and in terms of preferred embodiment, it is to be understood that the invention is not limited thereto. On the contrary, it is intended to cover various modifications and similar arrangements as would be apparent to those skilled in the art. Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
