BACKGROUND OF INVENTION  
         [0001]    1. Field of the Invention  
           [0002]    The present invention relates to an optical disk drive system, and more particularly, to a disk force-ejection and force-loading device for use in an optical disk drive.  
           [0003]    2. Description of the Prior Art  
           [0004]    A slot-in optical disk drive allows users to easily load and eject optical disks. Slot-in optical disk drives can be used in many electric appliances, such as lap-top computers, audio players, optical disk drives for computers, and car CD players. And the conventional slot-in optical disk drive can offer a user-friendly loading and ejecting mechanism.  
           [0005]    Please refer to FIG. 1. FIG. 1 is a drawing showing an optical disk  9   a  loaded into a slot  92  of a slot-in optical disk drive  9   b.  However, the optical disk  9   a  may not be ejected from the optical disk drive  9   b  if the loading mechanism fails, the circuitry of the optical disk drive  9   b  fails, power of the optical disk drive  9   b  fails, or the motor of the optical disk drive  9   b  fails. Under this circumstance, the only way to remove the stuck disk from the drive  9   b  is to disassemble the optical disk drive  9   b  and it is very inconvenient. Especially for car-use slot-in optical disk drives, it is also too difficult for common users to disassemble the optical disk drive  9   b  for removing the optical disk  9   a.  Thus, there is a need to design a force-ejection mechanism in the slot-in optical disk drive.  
         SUMMARY OF INVENTION  
         [0006]    It is therefore an objective of the claimed invention to provide a disk force-ejection and force-loading device for ejecting optical disks from an optical disk drive or loading optical disks into the optical disk drive when the loading mechanism fails, the circuit of the optical disk drive fails, power of the optical disk drive fails, or the motor of the optical disk drive fails.  
           [0007]    According to the claimed invention, a disk force-ejection and force-loading device for use in an optical disk drive is proposed. The optical disk drive includes an active gear of a drive motor for loading and ejecting an optical disk and a housing including a position hole nearby the active gear of the drive motor. The disk force-ejection and force-loading device includes a drive element installed on one end of the disk force-ejection and force-loading device for connecting and driving the active gear of the drive motor via the position hole, a motivity provider for rotating the drive element, and a power provider for providing electric power to the motivity provider.  
           [0008]    These and other objectives of the claimed invention will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment, which is illustrated in the various figures and drawings.

     DETAILED DESCRIPTION  
       [0017]    The embodiments according to the present invention are related to a slot-in optical disk drive. In fact, the present invention can be used in all kinds of optical disk drives including CD-ROM, CD-RW, half-height drives, combo drives, DVD-R/RW, external drives, optical players, and so on.  
         [0018]    Please refer to FIG. 2 and FIG. 3. FIG. 2 and FIG. 3 show a disk force-ejection and force-loading device  8  used in an optical disk drive according to the present invention. Please refer to FIG. 2. The disk force-ejection and force-loading device  8  includes a drive element  2 , a position element  3 , a motivity provider  4 , and a power provider  5 . The drive element  2  is for connecting and driving an active gear of a drive motor of the optical disk drive. The active gear of the drive motor can drive correlative components via a transmission gear to load or eject optical disks. The position element  3  is for fitting into a position hole on a housing of the optical disk drive so as to connect the drive element  2  with the active gear of the drive motor precisely. The power provider  5  provides electric power to the motivity provider  4  to rotate clockwise or counterclockwise so as to drive the drive element  2  to rotate clockwise or counterclockwise. Then the transmission gear can be driven to load or eject optical disks. Please refer to FIG. 3. The disk force-ejection and force-loading device  8  further includes a control switch  6  and an outer covering  7 . The control switch  6  is for switching the motivity provider  4  to rotate clockwise or counterclockwise. The outer covering  7  is for covering the motivity provider  4  and the power provider  5 .  
         [0019]    Please refer to FIG. 4 and FIG. 5. FIG. 4 and FIG. 5 show the optical disk drive and the disk force-ejection and force-loading device  8 . The optical disk drive includes a housing  1  including a position hole  11  for matching the position element  3  to precisely connect the drive element  2  and the active gear of the drive motor. The disk force-ejection and force-loading device  8  according to present invention can be plugged into the front of the housing  1  (A direction) or the side of the housing  1  (B direction) depending on the design of the position hole  11 . In a preferred embodiment, the terminal end of the active gear of the drive motor is toward to the side of the housing  1  (B direction). Please refer to FIG. 6. FIG. 6 illustrates a drive motor  9  and an active gear  91  of the drive motor  9  of the optical disk drive. The drive motor  9  and the active gear  91  of the drive motor  9  are located on a side of the optical disk drive. Please refer to FIG. 7 and FIG. 8. FIG. 7 and FIG. 8 show relationships of the drive motor  9  and a transmission gear  10 . Please refer to FIG. 9 and FIG. 10. FIG. 9 and FIG. 10 also show relationships of the drive motor  9  and the transmission gear  10 . The active gear  91  of the drive motor  9  can drive the transmission gear  10  to drive related components so as to load or eject an optical disk. The relationship of the drive motor  9  and the transmission gear  10  is changeable and can be designed in accordance with well-know principles.  
         [0020]    When the optical disk cannot be ejected from the optical disk drive because the loading mechanism fails, the circuit of the optical disk drive fails, power of the optical disk drive fails, or the motor  9  of the optical disk drive fails, the disk force-ejection and force-loading device  8  can be plugged into the position hole  11  according to the present invention. Please refer to FIG. 4. When the position hole  11  is on the front of the housing  1 , the disk force-ejection and force-loading device  8  is plugged into the front of the housing  1  (A direction). Please refer to FIG. 11. FIG. 11 shows the relationship of the drive element  2  and the active gear  91  of the drive motor  9  according to FIG. 4. A side of the drive element  2  engages a side of the active gear  91  of the drive motor  9 , and the direction of the major axis of the drive element  2  is perpendicular to the direction of the major axis of the active gear  91  of the drive motor  9 . The drive element  2  can be above or below the active gear  91 . Please refer to FIG. 5. When the position hole  11  is on the side of the housing  1 , the disk force-ejection and force-loading device  8  is plugged into the side of the housing  1  (B direction). Please refer to FIG. 12. FIG. 12 shows the relationship of the drive element  2  and the active gear  91  of the drive motor  9  according to FIG. 5. A terminal end of the drive element  2  is connected to a terminal end of the active gear  91  of the drive motor  9 . Alternatively, a side of the drive element  2  engages a side of the active gear  91  of the drive motor, and the direction of the major axis of the drive element  2  is parallel to the direction of the major axis of the active gear  91  of the drive motor  9 . After the drive element  2  engages the active gear  91  by the connection of the position element  3  and the position hole  11 , the power provider  5  can provide electric power to the motivity provider  4  to act according to the control switch  6 . Thus the motivity provider  4  can drive the drive element  2 , and the drive element  2  can drive the active gear  91  of the drive motor  9  to rotate in a disk-ejection direction. The active gear  91  of the drive motor  9  can drive the transmission gear  10  to drive related components so as to eject an optical disk.  
         [0021]    Furthermore, if a user wants to load an optical disk into the optical disk drive when the loading mechanism fails, the circuit of the optical disk drive fails, power of the optical disk drive fails, or the motor  9  of the optical disk drive fails, the disk force-ejection and force-loading device  8  can be plugged into the position hole  11  according to the method previously mentioned. After the drive element  2  engages the active gear  91  by the connection of the position element  3  and the position hole  11 , the power provider  5  can provide electric power to the motivity provider  4  to act according to the control switch  6 . The motivity provider  4  can drive the drive element  2 , and the drive element  2  can drive the active gear  91  of the drive motor  9  to rotate in a disk-loading direction. The active gear  91  of the drive motor  9  can drive the transmission gear  10  to drive the related components so as to load an optical disk.
