The second elastic member 5 is a second guide hole 313 which is abutted against the second frame 31, and the top plate of the base unit 1 12, the second frame is kept in contact with the second nut block 33. In the embodiment, the first and second elastic members 4, 5 are compression springs. The drive unit 6 has A screw 61 located in the base unit 1 and a motor 62 for driving the screw 61 to be pivoted and fixed to the bottom plate 13. The screw 61 has a first externally threaded section 611 that passes through the first through hole 212 and is screwed with the first internal thread 231 of the first nut block 23, and passes through the second through hole 312 and the second The second internal thread 331 of the nut block 33 engages with the threaded second externally threaded section 612. In this embodiment, the motor 62 is a stepping motor mounted in the base unit, and the first and second externally threaded segments 611 and 612 respectively have external threads of different pitches, and the first external thread. The outer diameter of the segment 6ι is greater than the outer diameter of the second outer thread segment 612. The guiding unit 7 is connected to the base unit 丨 and has an anti-rotation guide 71, an axial guiding member 72, and a guiding member 73. The anti-rotation guide 71 is located in the base unit , and can cooperate with the first and second anti-rotation guides 232 and 332 of the first and second nut blocks 23 and 33 to prevent the first The first nut blocks 23, 33 rotate with the screw 61. In this embodiment, the anti-rotation guide 71 is a guiding groove located in the base unit 1 , and the first and second anti-rotation guiding portions 232 and 332 are protruded from the first and the first Two nut blocks 23, 33 and bumps that can be guided by the guiding grooves. The axial guiding member 72 is disposed between the top and bottom plates 12 200903027 and 13 of the base unit ,, and the first and second axial guiding portions 211 corresponding to the first and second frames η and η. And 311, wherein the first and second frames 21 and 31 are guided to move parallel to the optical axis z. In this embodiment, the axial guiding member 72 is a guiding shaft connected to the top of the base unit 1 and the bottom plate 12, 13 parallel to the optical axis Z, and the first and second lens units 2' The first and second axial guiding portions 211, 311 of the 3 are all grooves through which the guiding shaft can pass. The guiding rod 73 is disposed between the top and bottom plates 12 and 13 of the base unit i parallel to the optical axis Z, and passes through the first and second frames 21 and 31. The guiding holes 213 and 313 are configured to guide the first and second frames 21 and 31 to move parallel to the optical axis z. The guiding rod member 73 is sequentially fixed to the top plate 12 by the bottom plate 13 through the first elastic member 4, the first guiding hole 213, the second guiding hole 313 and the second elastic member 5. Next, the principle of focusing operation of the present invention will be described in detail as follows: When the motor 62 is driven by a power source (not shown), the screw 61 is rotated, because the first and second nut blocks 23 and 33 respectively The first and second anti-rotation guides 232, 332 are engaged with the anti-rotation guide 71, so that the first and second nut blocks 23, 33 will not rotate with the screw, but The screw 61 is screwed in and screwed back. When the first and second nut blocks 23, 33 are moved toward the top plate 12, an elastic position of the first elastic member 4 can push the first frame 21 to push the first frame 21 constant. Touching the first nut block 23, at the same time, the second nut block 33 pushes the second frame body 31, so that the second frame body 31 compresses the second elastic member 5, and the second elastic member 5 is thus stored— The elastic potential energy, whereby the first and second frames 21, 31 are broken and away from the bottom plate 13, and the first and second lenses 22, 32 are therefore 200903027 away from the photosensitive element 11. Conversely, when the screw 61 is driven to rotate in the opposite direction to move the first and second nut blocks 23 and 33 toward the bottom plate 13, the elastic position of the second elastic member 5 can push the second frame. 31, the second frame 31 is constantly attached to the second nut block 33, and the first nut block 23 is pushed against the first frame 2 to compress the first frame 21 to compress the first elastic member. 4, the first elastic member 4 thus stores the elastic potential energy, whereby the first and second frames 21, 31 are driven while approaching the bottom plate 13, and the first and second lenses m are therefore close to the photosensitive element. The first and second externally threaded segments 611, 612 of the Tianyu child screw 61 have different pitch threads, so when the screw 61 rotates, the first and second frames 21, 31 move in the same time. The length of the trip is also different. The operator who produces the lens can design the pitch of the first and second externally threaded segments 6ιι, 6ΐ2 according to the optical characteristics of the first and second lenses (four) and the like, and then drive the first, The second lenses 22, 32 follow the ratio to move relative to the photosensitive element 11, causing the lens to perform a focusing operation. When the _ lens unit 2 is configured as the focusing lens unit 3 as a zooming lens group, the second element 2, 3 is moved relative to the photosensitive element 11 to achieve ambiguity (including focusing and squeezing, ..., ",, force month b, g the first and second lens units" - both as zoom lens groups enable early 7L 2, 3 with the photosensitive element 11 < η β - set in the first lens unit 2 horse, * 对焦 土 的 的 ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( 对焦 对焦 对焦 对焦 对焦 对焦 对焦 对焦 对焦 对焦 对焦 对焦 对焦 对焦 对焦 对焦 对焦 对焦 对焦 对焦 对焦 对焦 对焦 对焦 对焦 对焦 对焦 对焦The zoom function can be achieved. 10 200903027 ~ By the above description, the present invention has an advantage in that the first and second lens units 2 can be driven simultaneously by using only one drive motor 62. 3 Simultaneous movement to achieve the focusing function, so that the structure of the invention is more simplified without the need for complex suction fittings. Therefore, the production, the stand and the cost of the parts can be effectively reduced, and the volume of the lens can be reduced. The design change of the invention can be: The first and second The number of the sheets 22, 32 is one, and is integrally formed with the first and second frames 21, m M 31. However, the number of the first and second lenses 22, 32 may also be greater than - (not shown) And the first and second lenses 22 and 32 can also be separately molded and then mounted on the first and second frames 21 and 31 respectively, instead of being formed. 2. When the lens is produced and assembled, The first lens unit 2 is first threaded through the second outer thread segment 612, and then screwed into the first outer thread segment 6 ιι, and then the second lens unit 3 is screwed into the second outer thread segment M2. And the outer diameter of the first threaded section is larger than the outer diameter of the second outer threaded section 612. However, if the motor 62 of the driving unit 6 and the screw Μ are not assembled (not shown) and the first lens 2 is screwed from the first external thread segment 611, and the second lens unit 3 is screwed from the external thread segment 612 of the first Hurricane, and then the motor 62, 4 of the drive unit 6 is < 1 , the bolt 61 is assembled, in this case, the outer diameter of the second outer thread segment 612 can be dimpled to be specific to or larger than the first outer thread segment The outer diameter of 611.

The first elastic members 4, 5 are configured to absorb the backlash (f 61 is to refer to the fresh lens driving module of the present invention, wherein the first and second externally threaded segments 611, 612 are respectively associated with the first, The second nut blocks 23, 33 are screwed together to drive the first and second lenses 22, 32 to move at the same time to adjust the focus, which can be reduced for the sake of simplification: the structure of the lens is more integrated, and the production assembly is effectively reduced. And the cost of the parts, so 12 200903027 can indeed achieve the purpose of the invention. However, the above is only the preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, the application according to the present invention is advantageous. The simple equivalent changes and modifications made by the description of the invention are still within the scope of the present invention.
