Description:
BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to a keystroke apparatus for an optical disk drive, and more particularly to a keystroke apparatus for an optical disk drive that operates an optical disk drive conveniently. 
   2. Background of the Invention 
   An optical disk drive is an important component in a computer system for copying data, playing movies and dealing with data. Such optical disk drives may be, for instance, CD-ROM/DVD-ROM drives, CD-RW/DVD-RW drives or other similar devices. Service life of an optical disk drive has relations to quality of an optical disk drive, safe use and good maintenance of computer users. As for quality of the optical disk drive, computer users have no measure to control. However, safe use and good maintenance are two effective methods to improve service life of an optical disk drive for computer users. 
   A conventional keystroke apparatus is directly disposed on an optical disk drive. Referring to  FIG. 7 , a keystroke  4  of an optical disk drive  1  is exposed outside. A gap may be formed between a mating hole  3  of a front panel  2  of the optical disk drive  1  and the keystroke  4 . Thus, dust may enter easily into the optical disk drive  1  to cause reduction of service life of the optical disk drive  1 . In addition, before a tray  5  of the optical disk drive  1  enters into the optical disk drive  1 , it is inconvenient to press the keystroke  4  below the tray  5 . Sometimes, the tray  5  may be damaged accidentally. Understandably, some attempts have been taken to introduce a keystroke apparatus for operating an optical disk drive conveniently. 
   What is needed, therefore, is a keystroke apparatus for an optical disk drive operating an optical disk drive conveniently. 
   SUMMARY 
   A keystroke apparatus for an optical disk drive in accordance with a preferred embodiment of the present invention includes a computer bezel, an optical disk drive having a keystroke, a pressing member movably attached to the computer bezel and at least one spring causing the pressing member to come back to an original position. The pressing member has a resisting portion for abutting against the keystroke. When the pressing member is pressed, the resisting portion drives the keystroke to open or close the optical disk drive. 
   Other advantages and novel features of the present invention will be drawn from the following detailed description of preferred embodiment of the present invention with the attached drawings, in which:

   The optical disk drive  10  may be a CD-ROM drive or other devices, such as a DVD-ROM drive, a CD-RW drive, a DVD-RW drive and so on. The optical disk drive  10  includes a front panel  11  and a tray  14 . A keystroke  12  is attached to the front panel  11 . A cover  41  is pivotably attached to the computer bezel  40  at an upper portion. The computer bezel  40  has a flange  42  with a through hole  422  defined. 
   Referring to  FIG. 2 , a groove  43  is defined in an inner side of the computer bezel  40 . A pair of generally L-shaped positioning blocks  44  extends from the groove  43 . A stopping block  46  also extends vertically from an inner side of the computer bezel  40  adjacent to the groove  43 . A post  462  extends from the stopping block  46 . The cover  41  is pivotably mounted on the computer bezel  40  by a plurality of springs (not labeled). 
   Referring to  FIG. 3 , the pressing member  20  is slidably mounted to the computer bezel  40 . A pressing portion  21  is formed at one end of the pressing member  20 . A pair of protrusions  23  extends outwards from a middle portion of the pressing member  20 . A pair of opposite resisting portions  25  is formed on the pressing member  20 . Each resisting portion  25  has a slanted face for abutting against the keystroke  12 . A post  27  is formed on the pressing member  20  between the two resisting portions  25 . 
   Referring also to  FIG. 4 , in assembly of the pressing member  20 , the pressing portion  21  of the pressing member  20  extends transversely through the through hole  422  of the flange  42  of the computer bezel  40 . The two protrusions  23  are received into the two generally L-shaped positioning blocks  44  of the computer bezel  40 . The spring  30  is disposed around the post  27  of the pressing member  20  and the post  462  of the stopping block  46  of the computer bezel  40 . Thus, the pressing member  20  is movably mounted to the computer bezel  40 . The spring  30  is compressed. 
   When the pressing portion  21  of the pressing member  20  is pushed inwards, the resisting portion  25  of the pressing member  20  abuts against the keystroke  12  of the optical disk drive  10 . The tray  14  is actuated to extend out from the optical disk drive  10 . Then, the tray  14  of the optical disk drive  10  pushes the cover  41  of the computer bezel  40  to pivot outwards. When the pressing portion  21  of the pressing member  20  is pushed inwards again, the resisting portion  25  of the pressing member  20  abuts against the keystroke  12  of the optical disk drive  10  again. The tray  14  of the optical disk drive  10  enters into the optical disk drive  10 . Then, the cover  41  of the computer bezel  40  comes back to an original position due to a plurality of springs for preventing from entrance of dust. 
   Referring to  FIGS. 5 and 6 , a keystroke apparatus for an optical disk drive in accordance with a second preferred embodiment of the present invention includes the optical disk drive  10 , a pressing member  20 ′, two springs  30 ′, a computer bezel  40 ′. In the second preferred embodiment of the present invention, above-mentioned members such as the optical disk drive is the same to the first preferred embodiment of the present invention, therefore, the label of members is not changed and follows the label of members of the first preferred embodiment of the present invention. 
   The pressing member  20 ′ is slidably mounted to the computer bezel  40 ′. A pressing portion  21 ′ is formed at a front end of the pressing member  20 ′. A sliding portion  23 ′ is formed in a middle portion of the pressing member  20 ′. A stopping block  24 ′ is formed at one end of the sliding portion  23 ′. A resisting portion  25 ′ with a slanted face extends vertically from the stopping block  24 ′. A pair of posts  27 ′ extends vertically from the stopping block  24 ′ at right side and left side of the resisting portion  25 ′. A pair of protrusions  28 ′ extends outwards from a rear portion of the pressing member  20 ′. 
   A cover  41 ′ is pivotably mounted on the computer bezel  40 ′ by a plurality of springs (not labeled). The computer bezel  40 ′ has a flange  42 ′ with a through hole  422 ′ defined. A pair of hooks  43 ′ is formed on the computer bezel  40 ′. A groove  45 ′ is defined in an inner side of the computer bezel  40 ′. A stopping block  47 ′ also extends vertically from the inner side of the computer bezel  40 ′ adjacent to the groove  45 ′. A pair of posts  472 ′ extends from the stopping block  47 ′. 
   In assembly of the pressing member  20 ′, the pressing portion  21 ′ of the pressing member  20 ′ extends transversely through the through hole  422 ′ of the flange  42 ′ of the computer bezel  40 ′. The sliding portion  23 ′ of the pressing member  20 ′ is received into the two hooks  43 ′ of the computer bezel  40 ′. The rear portion of the pressing member  20 ′ is received into the groove  45 ′ of the computer bezel  40 ′. Two springs  30 ′ are disposed around the post  27 ′ of the pressing member  20 ′ and the post  472 ′ of the stopping block  47 ′ of the computer bezel  40 ′. Thus, the pressing member  20 ′ is movably mounted to the computer bezel  40 ′. The two spring  30 ′ are compressed. 
   When the pressing portion  21 ′ of the pressing member  20 ′ is pushed inwards, the two protrusions  28 ′ are stopped by the two posts  472 ′ of the stopping block  47 ′ to prevent the pressing member  20 ′ from tilting. Simultaneously, the resisting portion  25 ′ of the pressing member  20 ′ abuts against the keystroke  12  of the optical disk drive  10 . The tray  14  is actuated to extend out from the optical disk drive  10 . Then, the tray  14  of the optical disk drive  10  pushes the cover  41 ′ of the computer bezel  40 ′ to pivot outwards. When the pressing portion  21 ′ of the pressing member  20 ′ is pushed inwards again, the resisting portion  25 ′ of the pressing member  20 ′ abuts against the keystroke  12  of the optical disk drive  10  again. The tray  14  of the optical disk drive  10  enters into the optical disk drive  10 . Then, the cover  41 ′ of the computer bezel  40 ′ comes back to an original position due to a plurality of springs for preventing from allowing access to dust.
