The driving member 130 has a rod shape and is disposed on the side f of the suction type optical disc drive 100. A rack 131 is disposed on the back surface of the front end of the driving member 130. The rack 131 is cut in the front and rear: about half of the teeth, and the front cutting teeth 132 and the rear cutting teeth 133 are formed. 131 "131 and is coupled with the second gear 126, driven by the third gear 126, the heng drive member 130' is slid back and forth along the side of the suction-type optical disk drive 1 前后 back and forth. The guiding groove 134, the guiding end of the guiding groove 13 protrudes inwardly to form a retaining wall 135. In addition, the image sheet 70 140 is disposed on the side of the driving member 130, and includes a sliding plate 141 and a movable cup 142. And the slide rod 143. One side of the slide plate 141 is coupled with the side of the drive member, and can slide back and forth with the drive member 130. The slide plate 141 is provided with a plurality of sliding slots 144, and the linkage rod 142 is centrally and rotatably fixed to the machine. The shell u〇, the end slides along the chute 144 to drive the other end to rotate. The 143-end is rotatably fixed to the side of the optical disc drive 1 , and the actuating slot 145 is disposed in the insert rod The rotation end of the continuation 142 is moved at (10), and the driving member 130 drives the linkage rod 142 via the sliding plate 141 to drive the feeding rod (4) to rotate and enter the optical disc D.
