Embodiment Construction
[0055] Refer to attached below Figure 3-5 , to describe in detail an embodiment of the optical pickup substrate elevating device of the optical disc drive according to the present invention.
[0056] like image 3 as well as Figure 4 As shown, the shape of the main substrate 30 is formed as a rectangle, which constitutes the skeleton of the optical disc drive. The center of the main board 30 is formed in a rectangular shape penetrating up and down, and the optical pickup board 40 is mounted on this part.
[0057] Then, a tray (not shown) for moving the disc between the disc ejection position and the disc playback position is mounted on the main base 30 . The tray is located on the upper portion of the optical pickup substrate 40 .
[0058] The rear end of the optical pickup substrate 40 is supported on the main substrate 30 through the anti-vibration area 42 . The anti-vibration area 42 is formed of an elastic material, and while supporting the optical pickup substrate ...

An optical pick-up substrate elevating device of an optical disc drive mainly includes a main substrate and an optical pick-up substrate inside. The optical pickup substrate is supported by the main substrate through the shockproof area on both sides of its rear end. The spindle motor, rotary table and optical pickup are installed on the optical pickup substrate. There is a lifting linkage area at the front end of the optical pickup substrate. The interlocking area protrudes forward to form an interlocking protrusion, and the front end of the main substrate corresponding to the interlocking protrusion is equipped with a lifting guide rail. The lifting cam guided by the protrusion has a concave groove formed on the upper end of the lifting cam, and the anti-vibration zone support interlocking protrusion is installed, and the interlocking protrusion cuts off the transmission of noise and vibration between the main substrate and the optical pickup substrate. In the optical pickup substrate of the present invention, the lifting cam of the lifting guide rail is directly supported by the interlocking protrusion, so no additional lifting substrate is needed.
Description
(1) Technical field [0001] The present invention relates to an optical pickup substrate lifting device for an optical disc drive, in particular to an optical pickup substrate lifting device for an optical disc drive that lifts and lowers the front end of the optical pickup substrate corresponding to loading and unloading operations of an optical disc. (2) Background technology [0002] see figure 1 , 2 , figure 1 is a plan view showing the configuration of an optical disc drive according to the prior art, figure 2 It is a diagram schematically showing the configuration of a lifting optical pickup board of an optical disc drive according to the prior art. [0003] like figure 1 As shown, the main substrate 1 forms the skeleton of the optical disc drive. A substantially quadrangular through hole is formed in the center of the main substrate 1, and the optical pickup substrate 3 is mounted on the through hole. [0004] The rear end portion of the optical pickup substrate...
