Description of the invention (2) The disc is moved back and forth in the radial direction ::: Flat :: The write head cannot keep the decision. It may be combined, and the worker should read it here. There are two possibilities for the read / write head ^ ^ ^ ^ ^ Η, ^ ^ # The difference is that the operating direction of the read / write head cannot be kept flat; errors may occur; transportation is caused: the direction is inclined rather than perpendicular to the flat f of itself may occur. And because of reading and writing masterpieces; ^ film orientation,-vertical above the second guide. That is to say, the main spindle guide fish 1 in the two J disk players may cause the reading error of the reading and writing head, and the relative position of this is incorrect. At this time, the light cannot be read normally. ^ = Data is being recorded or copied. The quality of the data read from the disc: Therefore, the possibility of causing errors on the disc can be increased by:]: However, although this is free, it actually reduces I = Therefore, in order to avoid the problem, in order to make the read-write head = ^ there is still a certain limit. Take or write the data in the disc ^ surely move, and also to read and adjust the two guide rods in the disc drive, There is a guide bar adjustment device to take the error. To avoid the read-write head from reading 10 packs: W-relative-degree, in the adjustment device disclosed by J :: 768248, several guide bars of the optical disc drive are set to 0, 7 a master? Guide rod 103, a pair of shaft guide rods 105, eight, report, clothing 107, and a turntable device 1 0. As shown in Figure 1 = Palace: 1m disc (not shown) is placed on the turntable device 109 When reading from above,] Ά Γ must be level between the main shaft guide 〇3 and the countershaft guide 〇5 ^ Return = can read every data in the disc (not shown) accurately. Therefore, 'in the conventional optical disc drive 10, several guide rod adjustments are used to adjust the main shaft 1 ^ 7 The relative height of the guide rod 103 and the countershaft guide rod 105. However, the structure of the conventional guide rod adjustment device 107 is complicated, and its volume is the same. Page 6 571295 5. The invention description (3) is relatively large. Therefore 'The present invention provides a simple, practical and low-cost adjustment device to adjust the relative height of the two guide bars in the optical disc drive. Another brief description of the invention ^ In view of the above, in order to achieve the purpose of easily adjusting the relative height of the two guide bars in the optical disc drive, the present invention The invention provides an adjustment device for a read-write head guide rod, a guide rod for fine adjustment in the vertical direction. The adjustment device of the invention comprises a body, a retaining wall, an elastic piece, and an adjusting screw. The method is set on the base body. The adjusting wire fixes the elastic piece on the base body. The ## — the end presses and guides one end to provide a lateral force, and the end of the guide rod is pressed against the retaining wall. Adjustment device by tightening or loosening The whole screw deforms the elastic piece, and indirectly allows the guide bar to move along the retaining wall. The purpose and advantages of this creation after January and related illustrations will be more clear with reference to the following detailed description of the invention. The detailed description of the invention, has reached The present invention provides a guide rod adjustment device for easily adjusting the two inside the optical disc drive. In this consistent embodiment, the adjustment device of the present invention is finely adjusted in the vertical direction. The guide rod 21 has one end portion 571295 5 Explanation of the invention (4) 211. The adjusting device of the present invention includes a body 23, a retaining wall 25, an elastic piece 27, and an adjusting screw 29. As shown in FIG. The base body 23. One end of the elastic piece 27 presses the end portion 211 of the guide rod 21 to provide a lateral force, and presses the end portion 211 of the guide rod 21 against the retaining wall 25. In addition, the adjusting screw 29 fixes the elastic piece 27 on the base 23. The adjusting device of the present invention deforms the elastic piece 27 by tightening or loosening the adjusting screw 29 to indirectly move the guide rod 21 along the retaining wall 25 to achieve the purpose of finely adjusting the vertical height of the guide rod 21. As shown in FIG. 3, the elastic piece 27 of the present invention includes a first plate portion 271, a link portion 273, and a second plate portion 275. The first plate portion 271 has a first end 2711 and a second end 2713. A socket 277 is disposed in the first end 2 711 and is formed by bending the first end 2 7 11. The second plate portion 2 7 5 has a first end 2751. A first end 2731 of the link portion 273 is connected to a second end 2713 of the first plate portion 271. A second end 2733 of the link portion 273 is connected to a first end 2751 of the first plate portion 275. Here, the elastic piece 27 has a screw hole 2 7 9 in the center for the adjustment screw (not shown) to pass through. In addition, the first plate portion 2 71, the link portion 2 7 3, and the second plate portion 2 7 5 connected to the elastic sheet 2 are substantially Z-shaped. Although in this embodiment, the structure of the shrapnel 27 is substantially Z-shaped / however, the shrapnel 27 can be easily changed to other implementations in addition to the implementation of the above structure, which will not be described in detail here. As shown in FIG. 4, the adjusting screw 29 passes through a screw hole (not shown) in the elastic piece 27 and presses the first plate portion 271. At the same time, the first end 2711 of the first plate portion 271 presses the end portion 211 of the guide rod 21 to provide a lateral force, and the end portion 211 of the guide plate 21 is pressed against the retaining wall 25. The second plate portion 275 abuts the seat body ^

Description of the invention (5) ^ j, due to the action of the connecting rod portion 273, when the adjusting screw 29 is tightened or loosened ^ 2, the elastic piece 27 is squeezed and deformed, and the guide rod 21 is indirectly caused along the retaining wall 25. 1Move vertically. At this time, the first plate portion 271 and the second plate portion 275 remain substantially parallel. First, the adjustment of the present invention can only achieve the purpose of adjusting the vertical height of the guide rod 21 by using only an elastic piece 27 and a retaining wall 25 with a set screw 29. Due to the large volume and complicated structure of the conventional adjusting device 107, the device of the present invention can indeed achieve the purpose of simplifying the design and reducing the cost. As shown in Fig. 5, in this embodiment, three adjustment devices of the present invention are provided in an optical disc drive 20], 3, and 5. The optical disc drive 20 has a main shaft 2 and a secondary shaft guide 24. The adjusting device i is disposed on the main shaft guide rod, and the entire adjusting devices 3 and 5 are respectively disposed on the front and rear ends of the auxiliary shaft guide rod 24. The elastic pieces 13, 33, and 53 in the clothes sets 1, 3, and 5 respectively abut on the base 26 of the optical disc drive 20. The adjustment screws u, 31, = in the adjustment devices 1, 3, and 5 respectively press the elastic pieces 13, 33, and 53. And by tightening or loosening the adjusting screws 31, 51, the elastic piece 27 is deformed by pressing to change the degree of the elastic piece 13, 33, 53. At this time, by deforming the elastic pieces 13, 33, and 53, the main shaft guide 22 and the auxiliary shaft guide 24 are indirectly moved in the vertical direction along the retaining wall 28, respectively. Therefore, with the adjusting devices i, 3, and 5 of the present invention, the main shaft guide 22 and the counter shaft guide 24 in the optical disc drive 20 can arbitrarily adjust the relative vertical Gauls of each other.
