Machines, all of them ^; Insert a disc to read the disc = / recorded onto the disc. 4 will be poor in the sea, 'when using the CD player' when the disc is placed: the disc opportunity has a - piece structure to clamp the disc to the rotating motor of the disc player, and the rotating motor will have The design of the magnet allows the tablet member 15 to be attached to the rotary motor to clamp the optical disc. The tablet member is made of a material that can be adsorbed by the magnet. Therefore, the rotary motor rotates at a high speed 4, and the optical disc is There will be no falling off. On the other hand, when the optical disc is to be ejected from the optical disc drive, the optical disc has a design of a lifting mechanism which lifts the pressing member and releases the pressing member from the rotating horse 20 to create a space for the optical disc to be ejected from the optical disc. However, due to design problems, the lifting mechanism of the conventional optical disc drive will cause the pressing piece to tilt when it is lifted. Thus, the tilting design will increase the space occupied by the lifting mechanism in the optical disc drive and have insufficient space. That is, the overall size of the optical disc drive must be increased, but the optical disc drive has its fixed specifications, and there must be a space limitation problem in 5 • 1294116. Therefore, in a limited space, the optical disc drive mechanism can be fully raised and It does not affect the exit of the disc, but it is a question that must be considered by the designers of each CD player. [Invention] The present invention enables the above-mentioned actions to be performed in the optical disc drive room when the tableting member in the optical disc drive is detached from the rotary motor in the optical disc drive and then disengaged from the disc in the optical disc drive. The disc does not make it 10 15 20 because: 匕, the optical disc drive with the lifting mechanism of the present invention is used for reading a disc-frame, a sliding member, a first-rotating member, a - lifting-lowering And at least one second rotating member.

Please refer to FIG. 2 and FIG. 2 for a preferred embodiment of the present invention before being actuated; and FIG. 3 is a cross-sectional view of the present invention - the preferred embodiment is not actuated: 61 has been placed The main mechanism of the optical disc drive mechanism of the lifting mechanism, and the pressing piece 4 is in contact with and pressed against the disc 61, wherein the pressing piece ^ 15 is made of a material that can be adsorbed by the magnet, so that the pressing piece 4 can be lifted Referring to the drawings, FIG. 4 is one of the top views of the preferred embodiment of the present invention, FIG. 5 is a cross-sectional view of FIG. 4, and FIG. 6 is a comparison of the present invention. The preferred embodiment is exemplified in the top view of FIG. 2 and FIG. 7 is a cross-sectional view of FIG. 6. When the sheet member 4 is to be lifted, the first rotating member 2 is first rotated (this is the first step and 20 turns). The first contact portion 32 of the first lifting member 3 is slid upward along the first rotating member 2^the second contact portion 21, and the fifth socket portion 51 of the second rotating member 5 is attached to the first rotating member 2 The front portion 221 slides, and the first lifting member 3 slides up along the first socket portion lu of the frame 1, and moves the tablet member 4 upwards 13 I294116 Ϊ (Fig. 7^1 segment lifting action), FIG. 6 is a top view of the present invention. FIG. 8 is a cross-sectional view of the present invention. After the above operation, the second rotation of the second rotating guide member 2 of the second rotating member 5 is expanded and the splicing 邛 54 is the first opening of the rotating shaft toward the frame 1; The three contact portions 52 correspond to the fourth connection 10 15 of the pressing piece 4, and the upper pressing portion 4 continues to move upward (this is the second stage lifting movement). As shown in Figure 8 and Figure 9. The above-mentioned structure is used for the action of the flute, and the tableting member 4 can perform the _th-stage lifting and lowering==stage lifting operation, and the pressing piece 4 is detached from the optical disk drive, and is further separated from the optical disk drive. The foregoing actions are performed in the space, and can be prevented from being damaged by the pressing member 4 when exiting. 〃 The above embodiments are merely exemplified for convenience of explanation and the claims have been claimed. The range (4) described above is in the above embodiment. Rather than being limited to 20, FIG. 1 is an exploded view of a preferred embodiment of the present invention. Figure 2 is a top plan view of a preferred embodiment of the present invention before it is actuated. Figure 3 is a cross-sectional view of a preferred embodiment of the present invention before it is actuated. Figure 4 is a top plan view of a preferred embodiment of the present invention. Figure 14 is a cross-sectional view of Figure 4. Figure 6 is a cross-sectional view of Figure 6 showing a preferred embodiment of the present invention. Figure 8 is a top view of the present invention. Figure 9 is a cross-sectional view of Figure 8.
