When the light X ^ Α ο ^ sin near the slot-in disc drive 10 out of the center insertion day, the retractable lever 13 can be pushed back and rotated. Inhalation - The sensing disc D is extended to a suitable depth, that is, the opening (7) is rotated to enable the disc D to be fed into the slot-in disc drive 1 on the side of the pop-up. At the same time, by: piece; Γ3 =, positioning #17 at the rear end of the suction-type first-disc machine 10, the circumference of the rear end of the two-disc D' and guiding = the core 18 of the engine is raised, so that the m on the raft is moved to the boat 11 Then take the disc and play it.丨 丨 9 clips disc D, and however, 'inhalation type disc player 〗 〇 initially developed only for the diameter of 12 cm 1342013 large-size discs, in order to expand the scope of application, add discriminating size discs and other institutions, in order to apply 8 Centimeters small size disc D. However, the small-sized optical disc D is small, and the inhaled light that originally used the 12-cm large-sized optical disc is inserted into the space with a large size of the machine, so that the insertion path cannot be strictly limited. ^ When the small-sized optical disc D is inserted into the slot-type optical disc drive at the position shown in FIG. ,, the ejecting lever 16 and the ejecting lever 13 of the forward-extending A angle, the forces acting on the periphery of the optical disc D are respectively Η and F2. And the force? 1 and the opposite side and the direction is almost opposite, causing the force of the input rod 16 to dial the disc D to be offset by the ejecting rod 13 to cause the disc D card to malfunction, and the optical disc machine ig is reliable. degree. Therefore, there is still a problem in the reliability of the conventional suction type disc player to be solved. SUMMARY OF THE INVENTION The object of the present invention is to provide a suction type optical disc drive and a driving member thereof, which is provided with a retaining wall by a driving member, which limits the initial forward angle of the ejecting lever and avoids the first disc card to improve the inhaling. The reliability of the CD player. $Inventive--The purpose is to provide a driving part of the suction type optical disc drive, and part of the gear teeth on the moving rack (4) stop point, and the cutting is stopped. In order to achieve the object of the foregoing invention, the suction type optical disc drive of the present invention and the end of the drive member are provided with a rack 'relative drive member in the position of the stop point in the suction 1, 'disc machine' A plurality of gear teeth are cut away from the half 旳I, and the 彖 is protruded by one or two degrees. The detachment unit protrudes from the guide 1342013 into the guide groove, and the retaining wall is located at the start of the guide. In the last path of the position, when the suction-type optical disc drive is in the starting position, the guide tip is placed on the retaining wall 'via the unloading sheet ^, so that the tab end of the ejecting rod extends forward, 'maintains a small forward extension ANGLE ^ [Embodiment] The present invention is directed to the above-described (four), the rib means used and the effect thereof, and the preferred embodiment will be described below with reference to the drawings. Referring to Fig. 2, there is shown the internal structure of the portable optical disc drive (10) of the present invention. The slot-loading optical disc drive 100 mainly includes a casing 110, a transmission unit 丨2〇, a driving member 130, a feeding unit 14〇, and a ejecting unit 15〇. A driving unit το 120 is provided in the casing to supply power, and the driving member 13 is driven to slide back and forth. The driving unit 130 is connected to the feeding unit just connected to the unloading unit 150 to advance and retract the sheet. Among them, the inside of the machine 110 is hollow, the front end is the inlet and outlet 1丨丨, and the inner 112 of the inner machine 112 is disposed at the inner side of the casing ho near the inlet and outlet η], so that the movement 112 can be rotated and set in the movement. 112 the other end = the shaft motor 113 ' can rise or fall. The transmission unit 12() is disposed on the near-machine " and the U-shaped inlet and outlet 11 includes the transmission motor 121 and the gear set 122. The transmission motor 121 is a rotating power source. The gear set 122 is composed of a worm wheel 123, a w-th wheel 124, a second gear 125 and a third gear 126. The worm wheel 123 2 is coupled to the rotating shaft of the transmission motor 121, and the first gear 124 is After the worm wheel 123 is engaged, the second gear 125 and the third gear 126 are sequentially engaged. When the transmission motor 121 is rotated, the power may sequentially rotate the third gear 126 via the first gear 124 and the second gear 125 of the gear set 122. The driving member 丨 30 is in the shape of a rod, and is disposed on one side of the suction type optical disc drive 丨 00. The driving member 1 is provided with a rack at the rear end, and the rack 131 is cut by about half of the teeth on the front and rear teeth. Front cutting teeth 132 and rear cutting # 133. The teeth: 1 and only the second gear 126 is worn, driven by the third gear 126, and the driving member 130 is slid back and forth along the side of the suction disc drive 1 来回. The guide groove 130 is provided at the near end of the movable member 130, and the bottom edge of the guide groove 134 protrudes in the guide groove 34 to form a retaining wall 135. Further, the film feeding unit 4 is disposed on the side of the driving member 13A, and includes a sliding plate 14 and a feeding rod 142. The side of the sliding plate 14 is connected to the side of the driving member 30, and can be slid back and forth with the driving member. The sliding plate hi is provided with a plurality of sliding slots 144, and the connecting rod 142 is rotatably fixed to the end of the casing U〇' The chute 144 slides to drive the other end to rotate. The ejector rod 14 γ-end is rotatably fixed to the side of the optical disk drive ,, and the inside of the ejector lever < actuation groove 145, for the rotation end of the linkage rod M2 to slide therein, so that the driving member 130 is driven by the sliding plate 141 The lever 142 is interlocked to drive the blade to rotate into the disk D. The retraction piece 150 is disposed on the rear side of the casing 11〇, and includes a first corpse 15b second link 152 and a ejector rod 153. The first link 151 is movably disposed on the casing 110 at the rear end side of the driving member 13 at the other end, and the other end has a - first connection 154 and a protruding guide 155, and a guide 155 The inside of the recess 134 slid along the guide groove 134. The coupling shaft 154 of the second link 152 is coupled, and the other one is 祀ώ ^ + , and the reverse "rise / mate - two connecting shaft 156" extends to the other side of the machine. The ejector rod 153 - The end is rotatably fixed by the support shaft 157 to the rear end of the front side of the forehead 110, and the ejecting rod 153 is connected to the splicing joint 56, and the other is slanted to form a tab end 158. The driving member 13(4) can guide and push the movement/tip 155, so that the guiding rod 155 rotates the first connecting rod (5), and the moving rod 152' causes the second connecting rod 152 to drive the ejection rod 153, (4) the cup (5) The carriage is rotated by 157, and the tab end 158 is rotated. Therefore, when the slot-in disc drive 100 completes the advance and retreat, the element
