Fig. 8 shows the vertical view of the pedestal 40 of known CD-ROM device, does not wherein demonstrate laser disc pallet 1.Usually assemble ray machine module (TRAVERSE), Spindle Motor and traditional laser disc on the pedestal 40 of CD-ROM device and carrying unloading system.Rotating disk 51 is contained on the axle of Spindle Motor, be formed with on the housing of pedestal 40 left and right guide block 41-1 to 41-6 and left and right guide card 42-1 to 42-6.Left and right guide groove 18-1, the 18-2 compounding practice at the structure of aforementioned guide block and guide card and laser disc pallet 1 back side keep linear displacement when making pallet 1 turnover CD-ROM device, and left and right pin 44,43 are set in position.Also assemble driving gear set on the pedestal 40, comprise first gear 46, second gear 47 and the 3rd gear 48, and three gears are each other through tooth portion 49 mutual interlinkages, as shown in Figure 8, and rotate by CD-ROM drive motor 50 driven gears.The tooth portion 49 of first gear 46 and the tooth portion 18 mutual interlinkages of pallet 1 drive pallet 1 turnover CD-ROM device to reach.The present invention is mainly at pedestal 40 (or the fixed body of CD-ROM device; As: shell) further form second projection 45 on the ad-hoc location.To between the clamping device to second projection 45 and pallet 1 detailed explanation be arranged below.
Then with reference to figure 9,10 and 11, wherein Fig. 9 shows that the pallet 1 that carries CD-RW discsCD-RW is assemblied in the situation of the maximum released amount on the pedestal 40.At this moment, on the left and right lever 44,43 that the left and right stopper section 10-2 of pallet 1,10-1 are resisted against pedestal 40 respectively, the tooth portion 49 of first gear 46 and the tooth portion 18 of pallet 1 interlinkage each other.The operator can utilize the edge (or hand) of CD-RW discsCD-RW 30 to push clamping limb 20 its clamping parts 21 that protrude in breach 17 open and put into this CD-RW discsCD-RW 30 when placing CD-RW discsCD-RW 30.The clamping part 21 leading edge A of clamping limb 20 impose on radially holding force (please cooperate earlier figures 7 related description) of CD-RW discsCD-RW 30 1, thus when CD-RW discsCD-RW 30 is not carried than pallet 1 in the position of clamping limb 20 to rank wall L
3Outside skew, but the still outstanding rank wall L of the leading edge of clamping part 21
3Inboard (be laser disc put district in), and the flexible tongue-and-groove 22 of clamping limb 20 also has one section displacement apart from first projection 11.When CD-ROM device was carried out the action of video disc loading, driving gear set was driven motor 50 drivings and by the tooth portion 49 of first gear 46 and tooth portion 18 interlinkages of pallet 1 pallet 1 is entered in the CD-ROM device.During this is written into,, CD-RW discsCD-RW 30 enters in the CD-ROM device because being subjected to pallet 1.During this is written into, restrains and to make it can be parallel to pedestal 40 reposefully to advance towards rotating disk 51 because CD-RW discsCD-RW 30 is subjected to the radially clamping of pallet 1.Relative position when the inclined-plane 25 of clamping limb 20 and second projection 45 touch first is shown among Figure 10.And among Fig. 9 and Figure 10, clamping limb 20 is identical with the relative position of 11 of first projections.When pallet 1 continuation is mobile, the center pit 31 of CD-RW discsCD-RW 30 continues to advance towards rotating disk 51, and,, make clamping limb 20 to rank wall L so the inclined-plane 25 of the clamping limb 20 of pallet 1 its clamping device in moving will touch second projection 45 because second projection 45 is to be fixed on the pedestal 40
3Outside skew, as shown in figure 11.When pallet 1 entered in the pedestal 40 fully, the leading edge of clamping part 21 broke away from the edge of CD-RW discsCD-RW 30, and withdrawed from laser disc to put the district fully and do not hinder the rotation of CD-RW discsCD-RW.Therefore, CD-RW discsCD-RW 30 no longer is subjected to restraining of clamping device, but the side of CD-RW discsCD-RW 30 is subjected to the restriction of holding piece 52, and the lower edge of laser disc 30 has the rank wall L of pallet 1
2, L
3Provide support, so CD-RW discsCD-RW 30 can not break away from pallet 1 and put the district by being attached to laser disc reposefully.At this moment, the ray machine module moves closer to " loaded " position, and the rotating disk 51 of holding piece 52 and Spindle Motor adsorbs mutually and video disc 30 is fixed on the rotating disk 51, finishes video disc and loads action, as shown in figure 11.The release of aforementioned radial force and rotating disk 51 carrying CD-RW discsCD-RW almost are that synchronization is finished.
Continuation is with reference to Figure 11, and CD-RW discsCD-RW 30 is fixed on after the rotating disk 51, during rotation the edge of CD-RW discsCD-RW 30 not can with rank wall L
1, L
2, L
3Between cause interference.Simultaneously, after pallet 1 is loaded into the location fully, be noted that the relative position of each other between second projection 45, clamping limb 20 and first projection 11.At this moment, the position that second projection 45 is installed on the pedestal 40 just makes the clamping part 21 of clamping limb 20 be pushed away laser disc storing district, and the position of clamping limb 20 can't cause flexible tongue-and-groove 22 and first projection 11 that is installed in pallet 1 back side that the situation of buckle is arranged.In other words, when CD-ROM device is carried out when moving back the action of sheet, but the clamping limb 20 radially holding force recovered CD-RW discsCD-RW 30 of mat torque spring 12 still.
When ESC Escape was pressed, the ray machine module broke away from " loaded " position immediately, and the rotating disk 51 of Spindle Motor leaves CD-RW discsCD-RW 30, and was subjected to the restriction of above-mentioned clamping machine to CD-RW discsCD-RW 30, made it can not break away from pallet 1.At this moment, clamping device will recover the radially holding force to CD-RW discsCD-RW 30 with the inverted sequence action of aforementioned load module, and withdraw from pallet 1 smoothly to maximum released amount, as shown in Figure 9, will repeat no more video disc at this and withdraw from action.
With reference to Figure 12, demonstrate the inoperative state of clamping device of pallet 1.When CD-ROM device is installed with horizontality, the operator can manual mode be offset clamping limb 20 toward first projection 11, form the buckle state up to its flexible tongue-and-groove 22 and first projection 11, and the torsion of torque spring 12 can't make clamping limb 20 remove aforementioned buckle state.So, laser disc pallet 1 will carry out the action of forward/back sheet in the mode of tradition.Uprightly (edge-on) erecting bed is fashionable when CD-ROM device is applied to, and the operator still can manual mode remove aforementioned buckle state, and recovers the radially clamping strength of clamping device.
The embodiment system of above-mentioned pallet reaches the purpose of radially clamping CD-RW discsCD-RW in point-to-area mode.Figure 13 shows that laser disc pallet of the present invention has another embodiment of point-to-point radially method of clamping.And point-to-point radially clamping means the mode that video disc is stressed, is not to refer to 2 stressed situation.In upright (edge-on) attitude, only be subjected to 2 the application of force still may have the anxiety of rotation in CD-RW discsCD-RW, and firm inadequately.Therefore point-to-point force way has at least the CD-RW discsCD-RW application of force reached balance person at 3, can obtain stable clamp position.Among Figure 13, utilize above-mentioned clamping limb 20 to be disposed at D point place among the figure, so will make CD-RW discsCD-RW 30 that stress shown in Figure 14 is arranged.Be applied to CD-RW discsCD-RW 30 1 radial force F at the D point
D, and push it against rank wall L
1, L
2And obtain reacting force F at 2 E, F
E, F
F, so on D, E, F, obtain balance at 3 with three radial forces and firm CD-RW discsCD-RW 30 on pallet, wherein at E, F place, the reliability of rubber with the raising clamping device can be installed.
In addition, be disposed at the clamping limb 20 that D is ordered in another embodiment, when having the clamping part of arcwall face, can on the edge of CD-RW discsCD-RW, bestow the radial force of the mode of " face ", and still can obtain reacting force F at 2 E, F
E, F
F, so also can implement radially method of clamping in the face of point.The arcwall face of aforementioned clamping part can have the curvature identical with the CD-RW discsCD-RW edge, and more shape is tight to make therebetween contact.
In addition, the enforcement of radial force still has aspectant mode.Please refer to Figure 15, the radially clamping force mechanism of pallet 1 can change by aforementioned clamping device 60 with arcwall face to be implemented.When CD-RW discsCD-RW is placed on the pallet 1, can bestow radial effect power by the surface of arcwall face clamping device 60, and at rank wall L
1The surface obtain radial reaction force and come this CD-RW discsCD-RW of clamping.This is the radially clamping embodiment of acting force-reacting force.Then with reference to Figure 16, can dispose two or more radially clamping devices in position on the pallet 1, among Figure 16 radially clamping device 60,61 can bestow radial effect power and this CD-RW discsCD-RW of clamping to CD-RW discsCD-RW simultaneously, this is cancel out each other the radially clamping embodiment of balance of acting force.Similarly, aforementioned and the cambered surface of CD-RW discsCD-RW contact can have the curvature identical with it or in addition rubber processing to improve the reliability of clamping device.
Behind the various radially method of clamping of understanding the present invention, still just like the embodiment among Figure 17.Laser disc pallet 1 can be formed directly in the clamping limb 65 with flexible portion 66 on the wall L3 of rank, the design of this mode also can provide the embodiment of point-to-area as described above radially clamping.
The disc bearing device of being implemented according to the present invention with level/upright (edge-on) mode that CD-ROM device can be required is installed, improves the surcharge of CD-ROM device, promotes the market competitiveness of CD-ROM device.CD-RW discsCD-RW is in disc bearing device of the present invention, when CD-ROM device is installed with upright (edge-on) attitude, its radial force imposes on relative two places at CD-RW discsCD-RW edge at least, firm CD-RW discsCD-RW, make CD-ROM device in the process of carrying out the forward/back sheet, guarantee that CD-RW discsCD-RW passes in and out CD-ROM device and unlikely disengaging pallet in the mode that is parallel to pedestal; When CD-ROM device was installed with horizontal attitude, the operator can manual mode removes the radial force of pallet clamping device, recovered to carry in a conventional manner to unload action.
In sum, after describing various embodiment of the present invention in detail, being familiar with this technology personage can be well understood to, the present invention can carry out various variations and change not breaking away under following claim scope and the spirit, for example do not establish the flexible tongue-and-groove and first projection, can make CD-ROM device be exclusively used in uprightly (edge-on) installation occasion.
