As shown in Figs. 2 to 6, the optical disk drive device 1 of the present invention drives the operation of, for example, a 12 cm cm large-sized optical disk advance and retract. If not, when the large-sized optical disc C is inserted into the optical disc drive unit 1 , the width of the disc drive unit 10 is slightly larger than the diameter of the large-size optical disc c, and one side of the sheet C will abut against the side of the optical disc drive unit 10. The other two user thrusts first contact the feeding unit 50 and push the feeding pulley f 21 to gradually open the insertion lever 52 laterally, and the moving elongated shape drives the second driving tip 515 to slide. The auxiliary transmission rod 513 drives the transmission temple 51, the anti-return spring 53, rotates around the fixed center 511, and rotates the main lever 512 to let the first transmission tip 514 thereon drive the slot in the sliding member. , sliding along the third driving slot 434, under the non-moving slider 43, is moved from the second drive, the communication end of the slot 433 to the communication end of the first driving slot 432. _ As the optical disc C is gradually inserted, the optical disc C then touches the positioning unit 6〇θ' to simultaneously contact and push the first positioning rod 62 and the second positioning rod 63 with the arc edge thereof, so that the first positioning rod 62 The resisting limit spring 64 rotates around the rotating shaft of the i-shaped gear 611, and drives the positioning gear set 61 to rotate synchronously by the sector gear 611 to drive the gear set 612 to rotate synchronously, so as to fix the second positioning of the gear at the end of the positioning gear set 61.

The communication end of the slot 452 is moved toward the first guide slot 451. At the same time, the sector gear that rotates with the first positioning rod 62

The detector 81 is in the state of 0N. When both the first sensor 81 and the second sensor 82 are in the state of 0N, the optical disc drive device 1 can sense the inserted 1300554 611, and the edge will first touch the first The second sensor 82 is in an ON state although the second sensor 82 is turned on. However, the ejection lever 71 of the retractable unit 70 is only pushed by the optical disc C, and is retracted along the substrate 20. The sheet chute 22 is rotated, the first sensor 81 has not been touched by the eject lever 71, and is in an OFF state, and the disc drive device 1 has not yet discerned the size of the inserted disc C. As shown in FIG. 3, when the optical disc C is continuously inserted, the first positioning rod 62 and the second positioning rod 63 are gradually rotated by the positioning of the positioning gear set 61, and are gradually opened at the same distance from the spindle motor 31. When the two sensors 82 are in the state of 0N, the center of the guiding optical disc C is linearly moved to the spindle motor 31, and the ejection lever 71 is further pushed inwardly, so that the ejection lever 71 touches the first photosensitive disc into a large-sized optical disc. Slice C. When the optical disc c continues to be inserted, the first sensor 81 is maintained in the 0N state and moved to the end of the ejection lever 71, the positioning tip 621 of the first positioning rod 62 follows the positioning chute 21 and the third guiding groove 453 ' It is moved by the second guiding groove 452 to the communication end of the first guiding groove 451. At the same time, a driving end 514 is swung, and also along the third driving groove 434, and is connected to the end by a driving groove 432. The film lever 52 / moon wheel 521 also crosses the widest position of the disc c ^ ^ (: the outer edge of the arc. The blade position is fastened to the disc when the disc C continues to be inserted, and the first sensor 81 is retracted. In the 〇FF-like dry, 7 [away from the first sensor 81, the detector 82 is at 0N, and the first, as shown in Figure 4. In the second photosensitive disc drive device 1 will be established ^ = 2 When the device 81 returns to the state, the transmission motor 41 rotates the transmission motor 41 of the transmission gear set 40, and moves the slider 43. The first, driving rack 431 of the transmission rod 51 moves outwardly through the slot 432' and follows the first The driving slot 514 enters the first drive and the second transmission tip 515 moves in the elongated slot 522, and drives the input lever 52 to 1300554 via the auxiliary transmission rod 513 9 to push the optical disc C into the pulley 521 At the same time, the sliding member 43 also drives the column sliding slot 435 and the plate sliding slot 436 to move outward, forcing the protruding tip 441 and the guiding tip 454 to slide along the column sliding slot 435 and the plate sliding slot 436, wherein the protruding portion 441 first along the sliding member 43 In the axial direction, the sliding column 44 is maintained in the home position, and the guide tip 454 is laterally displaced along the oblique plate chute 436, and the sliding plate 45 is moved sideways along the chute 11. The positioning rod 621 is slid into the first guiding groove 451, so that the first positioning rod 62 resists the limiting spring 64, continues to rotate around the rotating shaft of the sector gear 611, and drives the positioning gear set 61 to rotate synchronously, so that the second positioning rod 63 is rotated. As the positioning gear set 61 rotates synchronously, the equidistance continues to open the linear guide optical disc C to the position. At the same time, the optical disc c also pushes the ejection lever 71 to rotate the rotary member 72. As shown in Fig. 5, when the transmission motor 41 continues to rotate. When the slider 43 is moved outward, the first driving slot 432 drives the first driving tip 514, so that the blade lever 52 continues to push the disk c into the blade with the pulley 521. The guiding 454 follows the plate slot 436. Sliding 'to make the sliding plate 45 continue to move sideways along the chute ,, the first guiding groove 451 drives the positioning tip 621 to move, so that the first positioning rod 62 drives the second positioning rod 63 to rotate synchronously, and continues to open the straight line at equal distances. The disc finally reaches the position of the embedded spindle motor 31, and a switch (not shown) is activated to start the movement 30 to rise, and the spindle motor 31 is embedded in the center hole of the optical disc (: while the convex tip 441 is also along the column chute. 435 oblique chute, lateral = The sliding column 44 is moved, and the optical disc C pushes the ejection lever 71 to rotate. The circle; r is not embedded in the center of the optical disc C? [After, the transmission motor 41 continues to rotate and moves outwardly to slide ===: pass 4 = let The two slider positioning pin 621+ moves, so that the first position lever 62 drives the two-step rotation to continue to open to disengage from the periphery of the contact optical disc c. At the same time, the dry slide '12 1300554 = 2 belt 435 'drives the convex tip 441 into the step The lateral movement slide = ^, so that the h-moving column 44 is tipped 442, just inserted into the first contact f of the rotating member 72, and the filament motor piece C is driven by the large-size optical disk Q-sheet process without the foregoing description. When the film is ejected, the if disc G is first separated from the wire motor 3b and then the drive motor 41 is reversed, so that the 41 reverse push the slider 43 to move inwardly, by the slider 43, the drive slot 432, the column chute 435 And the plate chute 436, respectively, drives the t-drive tip 514, the sliding column 44 and the sliding plate 45 to reset, so that the input button ίί2 is first retracted to the side, and the first positioning rod 62 drives the second positioning rod 63 to rotate and close simultaneously. The rotary drive motor 41 reversely rotates the ejection lever 7 to feed the optical disk C. Therefore, by using the optical disk drive device 1 of the present invention, the large-sized optical disk C can be smoothly positioned to complete the advance and retract. As for a small-sized optical disc of, for example, 8 cm, the film driving process of the present invention is as shown in Figs. 7 to 11 . As shown in FIG. 7, before the small-sized optical disc D is inserted into the optical disc drive device 10, the optical disc drive device 1 is in an initial state, that is, the transmission rod 51 is pulled by the return spring 53, so that the input lever lever is maintained at the deflecting machine. 30 piece position. The first positioning rod 62 causes the second positioning rod 63 to be interlocked by the positioning gear set 61, and the limited position is restrained, and the first positioning rod > 62 and the second positioning rod 63 are extended to the exit direction. The spindle motor 31 is equidistant on both sides. The one end of the ejecting rod 71 also extends toward the exit direction, is located near one side of the spindle motor 31, is retracted from the first positioning rod 62 and the second positioning rod 63, and is close to the spindle motor 31, so that the retracting rod 71, the first A positioning rod 62 forms an arc with the tab end of the second positioning rod 63 to wait for the tab. As shown in FIG. 8, when the small-sized optical disc jp is inserted into the optical disc drive unit 1 , since the width of the optical disc drive unit 10 is larger than the diameter of the small-sized optical disc D, the optical disc D lacks a side support and cannot push the pulley 52i. The 1300554 piece lever 52 is fully opened laterally, and even if the user pushes the push lever 52, the first positioning rod 62 is driven to touch the second sensor 82, because the small size optical disc detection switch It is assumed that the first sensor 81 is in the ON state, so that the w-second sensor 82 is in the ON state, the optical disc drive device 1 does not discriminate the disc size, and the drive motor 41' is erroneously activated to cause the card. Therefore, under the early pure blade thrust, the diaphragm D entering the optical disc drive device 1 is in contact with the first positioning sample 62 and the second positioning rod 63 with its arcuate edge/the center of the optical tablet D is automatically aligned. The spindle motor 31 and the pulley 52 of the input lever 52 are also urged against the optical disk D by the outer peripheral edge of the over-diameter, and the first transmission 514 is located at the communication end of the second driving groove 433. When the optical disc is continuously inserted, the optical disc D pushes the first positioning rod 62 against the limit spring 64 to rotate around the rotation axis of the gear 611, and drives the positioning gear set 61 to be tilted to fix the positioning gear set 61. The two positioning rods 63 move the second positioning rods 631 from the support slots 622 and the second positioning rods 62 and the second positioning rods 63 on both sides of the spindle motor 31, as the positioning gear set 61 generates synchronous interlocking rotation. Under the synchronous rotation of the positioning gear set 61, the spindle motor 31 is gradually opened at the same distance, so that the disc D of the optical disc D is directly moved to the position of the spindle motor. While the optical disc D pushes the first positioning rod (10) to rotate, the positioning tip 621 of the first position rod 62 is also positioned to slide along the overlapping substrate 20: 'and the third guide groove 453 of the sliding plate 45, moving to the second guide At the same time, since the arc of the small-sized optical disc D is curved and the diameter is small, the distance of the L-disc D to push the ejecting lever 71 on the path is greater than the distance of the ejecting of the first positioning rod 62, so that the distance is increased. The ejection lever 71 is larger than the first sensor 81. = Fig. 9 ^ When the optical disc D continues to be inserted, the eject lever 71 touches the second sensor 81, so that the first sensor 81 is in the (10) state, and the first positioning=62 still does not touch the second sensor 82, In the FF state, it is discriminated that the size of the inserted optical disc D is a small-sized optical disc, and the transmission motor 14 is immediately activated, so that the transmission motor 41 rotates the transmission gear set 42, and the drive rack 431 moves the slider 43 outward. The first driving end 514 of the transmission rod 51 is inserted into the second driving groove 433 and slid along the second driving groove 433, and the second driving end 515 is moved in the elongated slot 522 via the auxiliary transmission rod 513 to drive the input lever 52. Rotating, pushing the disc D into the sheet by the pulley 521. At the same time, the sliding member 43 also drives the column chute 435 and the plate chute 436 to move outward, forcing the protruding end 441 and the guiding end 454 to follow the column chute 435 and the plate chute. The 436 slides, wherein the protrusion 441 first slides along the sliding member 43 in the axial direction, the sliding column 44 is maintained in the original position, and the guiding end 454 is moved laterally with the oblique plate sliding groove 436, so that the sliding plate 45 is along the sliding path. 11 follows the side shift, so that the positioning tip 621 slides into the second guiding slot 452, so that the first positioning rod 62 resists the limit.箦64, continuing to rotate around the rotating shaft of the sector gear 611, and driving the positioning gear set 61 to rotate synchronously, so that the second positioning rod 63 rotates synchronously with the positioning gear set 61, and continues to open the linear guiding optical disc D to the same distance to At the same time, the optical disc j) also pushes the ejection lever 71 to rotate the rotary member 72. As shown in Fig. 10, when the transmission motor 41 continues to rotate and moves the slider 43 outward, the second drive slot 433 drives the first transmission tip. 514, let the tablet dial 52 continue to push the disc with the pulley 521]), and the guide 454 slides along the sliding slot 436, so that the sliding plate 45 continues to move along the slide 11 side, f enough = guide slot 452 drives the positioning pin 62丨 to move, so that the first positioning rod 62 belt=, the second county fixed f-bar 63 synchronously rotates 'equal distance to continue to open the straight line guide optical disc husband ^^ Iff reaches the position of the embedded spindle motor 31, and touches a switch (The figure "hole rfi core rises from 30" allows the spindle motor 31 to be embedded in the disc D: two-motion = 435 oblique chute, lateral rotation. After the disc D pushes the eject lever 71 to drive the rotary member 72, the shaft motor 31 is inserted into the center hole driving groove 433 of the optical disc D to drive the second member 43, so that the second slightly 514 allows the pulley 15 of the blade lever 52 15 1300554 Leaving the periphery of the disc D. The guide 454 continues along the plate to cause the sliding plate 45 to continue to move sideways along the slide U, so that the first "j move m" is opened to disengage the peripheral edge of the optical disc D. The same as the u 43 drives the column chute 435, driving the protrusion 441 column 44, so that the sliding column 44 is tipped 442, just inserting the rotation direction to the disengagement hole 722, and pushing the rotating member π to further rotate, and the upper edge of the disc is 'to complete the positioning, so that the disc two D: Without touching other components, it is rotated by the spindle motor 31. The foregoing description drives the process of feeding the small-sized optical disc D. The retreat = disc D is separated from the spindle motor 31, and then the drive motor 41 is reversed, so that the 41 reverse push slides # The first driving slot 433, the column sliding slot 435 and the plate sliding slot 436 respectively drive the first driving slot 514, the sliding column 44 and the sliding plate to be reset, so that the first positioning test is performed. 62 drives the second positioning rod 63 to synchronously rotate and close, and rotates the ejection lever 71 to rotate the ejection lever 71 to send the optical disc d. Therefore, the optical disc driving device of the present invention can synchronize the two positioning rods by positioning the gear set Simultaneously, the spindle motor is opened or closed synchronously, and is connected to the tab. The circular arc of the optical disc enables the optical discs of different sizes to automatically align the spindle motor and linearly enter the embedded positioning to enhance the positioning accuracy of the optical disc to reduce the optical disc drive device and avoid damage to the optical disc drive or the optical disc. At the same time, the driving groove, the column sliding groove and the plate sliding groove are formed on a single sliding member, which not only simplifies the structure of the driving unit of the optical disk drive device, saves assembly time and reduces cost, and can drive the two positioning rods to be synchronously closed, The optical disc driving method of the present invention is as shown in FIG. 12, and the steps of the control flow are as follows: Step S1: Insert the optical disc into the optical disc drive device to start the film feeding operation. 16 l3〇 〇 554 Step S2: detecting whether the first sensor 8i (SW1) is in an ON state.
