Description of the invention: [Technical field to which the invention pertains] The present invention relates to a type of optical disc, which is particularly concerned with inhalation <disc, heart, movement to guide the movement of the optical disc into the direction of the optical disc. [Prior Art] w meaning. After the human disc player is inserted into the disc player by human power, the number of positioning rods in the clever disc is used to automatically drive the disc to reach the playing position, and the direction of the disc is not correctly inserted into the disc, so that the disc is made. The dry tn shows that the conventional optical drive 10 is inserted into the r12 of the first disc 11 and the second disc has the upper and lower movements: the cover 15, the third motor has a spindle motor 14, and the movement 13 has a Protection inside _ near? extension end i6, position disk drive ig entrance π (four) moving picture / display), start the suction type CD player from the spindle tab 螭 guide the optical disc 11 to the spindle motor 14 positioning, = two rotation = piece 11 'When reading and writing the coffee disc π, "; = the extended end 16 is in a horizontal state, when the uninserted light entrance d 13 falls to a lower position in the casing 12, approximately at the exit and thus enters the suction in the optical disc 11 The 1 〇 channel of the CD-ROM drive, when it is inserted into the inlet and outlet 18, will cause the front end of the optical disk 11 to cause the optical disk to be on the lower edge of the positioning rod 17'. Not only the disk drive 10 automatically drives H; f correctly pushes the rotation 17 to initiate the suction. Light-input optical disc drive 1 misrepresents ii1 to positioning, even touching other components, guide In the suction structure, there is still a problem that the temple solves the death. Therefore, the conventional suction type optical disc drive 10 is in the present invention. The object of the present invention is to provide a disc drive movement to avoid the card P disc. The reliability of the operation of the horse. « : The purpose of the disc movement protection groove of the present invention is - the end is: round hole ' - the long hole extends from the circumference of the round hole to the other end of the = in the actuating groove The end of the end forms a bend, and then extends to form a platform-like extension end. The extension end is close to the lower end of the population of the suction-type optical disc drive, and is inclined from the entrance and exit to the inner slope of the suction optical disc drive to the tab end of the positioning rod. The use of the bevel angle [Embodiment] The invention is based on the technical means and the potting effect, and the preferred embodiment is described below with reference to the following figure. /, Please refer to Fig. 2 ' The optical disc drive core 2 of the present invention has a package 21, a protective cover 22, a spindle motor 23 and an optical pickup 24. Among them, the 框架 的 frame of the ϊ ® 分散 分散 分散 分散 分散 分散 分散 分散 分散 数 数 数 数 数 数 数 数 数 数 数 数 数 数 数 数 数 数 数 数 数 数 数The protective cover 22 is a flat plate covering the upper surface of the body 21, The cover 22 is axially excavated - the actuating groove 22 is formed as a double circular hole 222, and the long hole 223 is extended from the periphery of the circular hole 222 to the other end of the groove 221. The protective cover 22 forms a bend at the end of the actuating groove 221. Folding 22 ί, ΐϊ or extension constitutes a platform-like extension end, the extension end 225 is toward the end & the downward slant angle - angle Θ (please refer to Figure 3). The spindle motor 23 is mounted in the circular hole 222 'for Rotating a disc 25 (refer to FIG. 3), and the head 24 is disposed in the elongated hole 223 and can slide back and forth along the long hole. As shown in FIG. 3, the optical disc of the present invention is installed. The machine movement 2 is driven by the suction machine 30. The inhalation disc drive 3 includes an access port 31 and a positioning rod 32 for the light guide disc 25. The optical disk drive 2 is disposed in the suction optical disc drive 3〇200811838, and the extended end 225 is close to the lower side end of the entrance and exit 31, so that the downward oblique angle, 6►, and the extended end 225' are moved from the entrance and exit 31 to the suction optical disc drive. The inner side of the 3 逐渐 is gradually raised, and its oblique angle 0 is just extended to the tab end 33. Further, the spindle motor 23 is located on the inner side of the suction disk unit 3〇. The positioning lever 32 is fed from the rear side of the optical disk drive 30 over the spindle motor 23, with its tab end 3 3 extending toward the entrance and exit 31. When the optical disc 25 is inserted into the entrance and exit of the optical disc drive, the front end of the optical disc 25 is guided by the extended end 225 of the protective cover 22, and is inserted along the extending end 225 of the protective cover 22 by an angle θ, and is inserted in the upward tilt direction. In the optical disc drive 30, the front end of the optical disc 25 is directly moved to the tab end 33 of the positioning rod 32, contacts the tab end 33, and is guided by the positioning rod 32 to enter the suction disc player 30 to position the optical disc 25. Therefore, the optical disc movement cover of the present invention protects the extension end of the crucible by tilting the movement, so that the extension end is directed from the entrance and exit toward the rear side of the optical disc drive, and is inclined at an angle to the dead end, so that the inclined end of the extended end is inclined to the positioning rod. In order to guide the angle of insertion of the light stone=the piece, the front end of the optical disk piece is moved toward the f-piece end of the positioning rod along the inclined surface of the extending end, so as to avoid the insertion of the lower edge of the tab end 33, and the optical disc is prevented from being scratched by the tab end. At the same time, it can also ensure that the front edge of the optical disc is moved to the end of the tab, and the positioning of the positioning rod is guided to the positioning to improve the reliability of the operation. 10^············································································ The inclined extension end and the protection hole ^ ^ knife open, in order not to be fixed on the movement, or directly forming the extension end in the machine = death, can achieve the object and effect of the present invention, all of which belong to the technology of the present invention The present invention is not limited to the preferred embodiments, and any modifications made in accordance with the present invention are included in the present invention without departing from the spirit of the present invention. The scope of the patent application. 200811838 [Simplified description of the drawings] Fig. 1 is a schematic view showing the operation of a conventional slot-loading optical disc drive inserted into an optical disc. 2 is a perspective view of the protective cover of the optical disc drive of the present invention.
