Concrete implementation content
The present invention discloses a kind of fulcrum arrangement of CD, and this fulcrum arrangement is used in the CD-ROM drive, for loading and moving CD.
See also Fig. 1 a, Fig. 1 a is the synoptic diagram of the embodiment of the invention one.CD-ROM drive 100 comprises a supporting arm (loading arm) 10, one clamping part (holding device) 20,1 first guide rod 31 and one second guide rail (guide rail) 32.Supporting arm 10 has one first end 11, one second end 12 and one the 3rd end 13.First end 11 and second end 12 be socket first guide rod 31 and second guide rail 32 respectively.Because the guide function of first guide rod 31, second guide rail 32, so supporting arm 10 moves along first guide rod 31, second guide rail 32.In addition, clamping part 20 rotatably is arranged at the 3rd end 13, for clamping one CD 50.Thus, CD 50 is still rotatable after being held on the clamping part 20, and by supporting arm 10 carryings and mobile.
CD-ROM drive 100 also has a drive unit (driving device) 30.If the first above-mentioned guide rod 31 is a lead screw (lead screw), then drive unit 30 can drive this first guide rod, 31 rotations, and then makes supporting arm 10 move and rotate along first guide rod 31.
Fig. 1 b is the cut-open view of I-I line segment among Fig. 1 a.Clamping part 20 also comprises a gripper jaw 21 and a reference column 22.Gripper jaw 21 is in order to chucking optical disk 50, and reference column 22 is in order to be positioned clamping part 20 on the rotation platform 40.This rotation platform 40 is driven by a whirligig 41, makes rotation platform 40 drive CD 50 rotations.And about reference column 22 and rotation platform 40, then be the magnetic material that can attract each other, for example magnet and iron are so located and are fixed on the rotation platform 40 in order to help clamping part 20.
In addition, rotation platform 40 in present embodiment one is motionless in CD-ROM drive with the stationkeeping of whirligig 41, therefore, when CD 50 will withdraw from CD-ROM drive 100, clamping part 20 needs upwards to promote earlier to break away from rotation platform 40, so could further CD 50 be withdrawed from outside the CD-ROM drive 100, to avoid mutual bump.So one second guide rail 32 of present embodiment has a warp architecture 321.When supporting arm 10 when warp architecture 321 moves, second end 12 of supporting arm 10 upwards promotes gradually, so can change the height of clamping part 20.Therefore, when clamping part 20 breaks away from rotation platform 40, can avoid CD 50 in moving process, to collide rotation platform 40.
In addition, load and unload CD 50 for making things convenient for the user, supporting arm 10 also comprises one collapsible (foldableunit) 14.This collapsible 14 can upwards be overturn outside supporting arm 10 withdraws from CD-ROM drive 100 time, make clamping part 20 can be revealed in the angle that makes things convenient for the user to load and unload CD 50, shown in Fig. 1 c.
See also Fig. 2 a and Fig. 2 b, Fig. 2 a and Fig. 2 b are respectively II-II line segment cut-open view among the synoptic diagram of the embodiment of the invention two and Fig. 2 a.CD-ROM drive 200 comprises a supporting arm (loading arm) 10, one clamping part (holding device) 20,1 first guide rod 31, one second guide rail (guide rail), 32, one drive unit (driving device), 30, one rotation platform (turn table), 40 and one whirligig (turningdevice) 41.
Supporting arm 10 has one first end 11, one second end 12 and one the 3rd end 13.First end 11 and second end 12 be socket first guide rod 31 and second guide rail 32 respectively.Because the guide function of first guide rod 31, second guide rail 32, so supporting arm 10 can move along first guide rod 31, second guide rail 32.Clamping part 20 rotatably is fixed in the 3rd end 13, for clamping one CD 50.Thus, CD 50 is still rotatable after being held on the clamping part 20, and by supporting arm 10 carryings and mobile.First guide rod 31 comprises a lead screw (lead screw), and then drive unit 30 can drive this first guide rod, 31 rotations, and then supporting arm 10 is moved along first guide rod 31 and second guide rail 32.
Clamping part 20 also comprises a gripper jaw 21 and a reference column 22.Gripper jaw 21 is in order to chucking optical disk 50, and reference column 22 is in order to be positioned clamping part 20 on the rotation platform 40.This rotation platform 40 is driven by whirligig 41, makes rotation platform 40 further drive CD 50 rotations.And about reference column 22 and rotation platform 40, then be the magnetic material that can attract each other, for example magnet and iron are so located and are fixed on the rotation platform 40 in order to help clamping part 20.Same, loading and unloading CD 50 for making things convenient for the user, sway brace 10 also has one collapsible 14, in order to upset clamping part 20.
Different with embodiment one is that these whirligig 41 may command rotation platforms 40 rise and descend.Therefore, second guide rail 32 there is no warp architecture 321, and second end 12 of supporting arm 10 can upwards not promote in moving process yet.So when supporting arm 10 withdrawed from CD-ROM drive 200, rotation platform 40 can descend earlier, shown in Fig. 2 c, makes clamping part 20 separate with rotation platform 40, so, in the process of advance and retreat CD-ROM drive 200, CD 50 just can not collide rotation platform 40 in supporting arm 10.
By the above detailed description of preferred embodiments, can know more and describe feature of the present invention and spirit, and be not to come category of the present invention is limited with above-mentioned disclosed preferred embodiment.On the contrary, its objective is that hope can contain various changes and have in the category that is arranged in the claim that the present invention will apply for of equality.
