It 151 = i is the case where the optical disc drive 10 draws out the optical disc. The moving horse rotating member 153 moves forward, so that the sliding plate 141 slides in along with the first guiding end 1422 of the swinging rod 142 and drives the feeding lever 143 along the third guiding groove κ η Disc 'Because the disc D is being pulled away, the disc D cannot continue. ί2: ΪΖί The end of the positioning lever 173. The ejecting lever 163 ^ rotates to drive the second link 162 and the first link 161, and the movable end 1611 cannot be rotated. The forward sliding member 153 simultaneously releases the second 1611 to release the leaf spring 1531, and causes the slider 1532 to restrict the second one, 1611 from entering the side of the first slot 1539 of the first slot 1533, and the length of the first link 161 is rotated. Under the limit, the block 1538 is blocked, and the I-disc disc D is positioned to the third chute 1535. In addition, the slider 153 driven by the transmission 5 is also prevented by the first driving tip 1611 from being stopped by the stopper 1538 to raise the anger 13 ' to avoid the slow-drawn optical disc D, which is scratched by the ascending movement 13 or Pressure loss. The movement of the slider I53 is blocked, the slider 153 cannot move forward to release the first sensing switch 192 to stop the start of the transmission motor 151 and the counting time, when the timing of starting the transmission motor 151 exceeds the predetermined time, about 1-3 seconds, The predetermined time is the number of turns of the optical drive 1 〇 under normal conditions, the drive horse 13 1328799 reaches 151, enough to drive the slider 153 to shift to the position of the optical disc D, and move forward to release the second sensing switch 192. Time, ''If the second sensing switch 192 is released within a predetermined time, it means that the optical disk drive is operating normally, otherwise it is abnormal. When the predetermined time is exceeded, the driving motor 151 is reversed, and the sliding member 153 is driven to move backward, and the driving and unloading is driven. The rod 163 is rotated outwardly, and the film is reversed. The slider 153 operates the third sensing switch 193 to reset the advance and retract mechanism to the position of FIG. 4, and then stops the driving motor 151 to feed the disc player 10 next time. As shown in FIG. 7, it is a state in which the small-sized optical disc c is abnormally fed. When, for example, an optical disc C of 8 cm is inserted obliquely into the optical disc drive as indicated by the arrow, the optical disc C can push the tab end of the ejecting lever 163 to cause the push-retracting lever 163 to rotate and be set. The tip 1631 applies a force to the second link 162, rotates the first link 161, moves the first driving tip 1611 away from the initial slot 1539, and moves the second link 162 to release the second contact 1622 thereon. The sensing switch 191 is in the "off" state, and the optical disk drive 10 will immediately start the transmission & the motor 151 'rotate the gear set 152' to drive the slider 153 to move forward while starting to count the time when the transmission motor 151 is started. ° Since the small-size optical disc C completely falls into the optical disc drive 1 , the retractable lever 163 cannot be pushed continuously, and the first drive end 1611 is driven by the initial slot 1539 to pass the stop 1538 even after the transmission motor 151 is started. The motor 151 continues to drive the slider 153 to move forward, so that the slider 141 moves forward, and the first guiding end 1422 of the transmission rod 142 slides in and slides along the third guiding slot 1413 to drive the rotating transmission rod 142. The film lever 143 is rotated toward the dialing disk. However, the small-sized optical disk C moves the filming lever 143 by a distance, and the small-sized optical disk c can no longer be pushed to continue to push the blade 163 and the positioning bar.接3's tab end. The ejection lever 163 cannot be rotated, and the second link 162 and the first link 161 are continuously driven, and the first driving tip 1611 cannot be rotated continuously to move forward of the sliding member 153, and the stopper 1538 is blocked from the first driving. = Tip 1611, under the rotation limit of the first link 161, the first driving tip ΐ6ΐι 1328799 cannot be moved to the 达 杜 L L L ― β slot 1534 driven by the fixed 151 of the small-sized optical disc c.
