Reversible storage mechanism. [Prior Art] A telescopic (imaging) lens of an optical device such as a digital camera is generally a zoom lens, that is, a zooming effect is achieved by changing the relative positions of a plurality of groups of mirrors relative to each other. This kind of lens can be fully retracted when the optical device is closed, and it is extended when it is opened. Therefore, it has the advantages of being light and thin and portable compared to a large fixed zoom lens. In conventional retractable photographic lenses, one, one or more sets of movable mirror groups can only be moved in the direction of the photographic optical axis. However, after retracting the retractable lens, its length cannot be less than the total thickness of all optical components, and thus the thickness of the body cannot be further reduced. In view of the above, Japanese Laid-Open Patent Publication No. Hei 07-199019 discloses a lens barrel which can shorten the length of the lens. The figure is a summary of a conventional lens barrel disclosed in Japanese Patent Laid-Open No. 00 07-199019. In FIG. 1, when the lens is in a sinking state, the internal conversion lens 11 is away from the optical axis, and the internal conversion lens 11 is inverted to the side of the second lens 5 with the rotation axis of the vertical optical axis. 2A is a cross-sectional view showing the conventional lens barrel in a wide-angle shooting state; FIG. 2B is a cross-sectional view showing the conventional lens barrel in a medium-focus shooting state; and FIG. 2C is a schematic view showing the conventional lens barrel. A section view of the long focus shooting state. The internal conversion lens 11 is inverted on the optical axis by the axis of the vertical optical axis, and is positioned between the first lens 1 and the second lens 5. However, in the shooting state, insertion or removal of the internal conversion lens 11 causes a temporary interruption of the image; and the internal conversion lens 11 is inserted between the first lens 1 and the second lens 5 between 0757-A21238TWF(N2); O0105261 5 1273302. It is necessary to be coaxially aligned with the optical axes of the first lens 1 and the second lens 5, and if the grip portion 12b holding the internal conversion lens 11 is not coaxial during operation, the captured image is blurred. Therefore, in order to overcome the defects of the above-mentioned prior art, it is necessary to provide an innovative optical component storage mechanism which can reduce the length and thickness of the retractable optical device to achieve the purpose of thinness and shortness, and has a simple structure. Easy to assemble. SUMMARY OF THE INVENTION A primary object of the present invention is to provide a reversible storage lens set and a method of turning the same.

After the external gear set is driven by a motor (not shown), the rotary cylinder 70 rotates in the direction of the optical axis OA in the space of the fixed cylinder 80 and the base 90. Then, the rotary cylinder 70 is transmitted to the operation through the inner cylinder 60. The cylinder 50 is caused to cause a rotary motion of the operating cylinder 50 in the inner cylinder 60 in the direction of the optical axis OA. The operation cylinder 50 drives the first lens barrel 20 and the second lens barrel 30 to linearly move in the optical axis direction, whereby the distance between the first lens barrel 20 and the second lens barrel 30 changes to a zoom function. On the base 90, there is a third lens group 91 that moves in the direction of the optical axis OA and can be inverted about the axis of the vertical optical axis OA, φ, and a drive that drives the third lens group 91 to move in the direction of the optical axis OA and is inverted about the axis of rotation. Part 93. Fig. 4 is a view schematically showing an exploded view of the base of the reversible storage lens unit of the present invention and the third lens unit. Referring to Figure 4, the third lens group 91 is adjacent to the imaging surface for modulating the back focus to maintain the image plane position on the CCD (not labeled). The third lens group 91 includes a moving frame 911 that moves in the optical axis OA direction, a third lens group 912, an inner frame 913 that fixes the third lens group 912, and a torsion spring 914. When the image of the object is captured, the inner frame 913 is carried by the moving frame 911, so that the inner frame 913 linearly moves in the direction of the optical axis ΟA. 0757-A21238TWF(N2); O0105261 9 1273302 In a specific embodiment of the present invention, the moving frame 911 has four frames 911 A, 911B, 91TC, and 911, wherein a frame edge 911A has a radial direction perpendicular to the optical axis OA. The platform 9112 has a first through hole 9113 and a second through hole 9114 penetrating in the optical axis OA direction. Further, on the side of the frame, there is a third through hole 9115 penetrating in the direction of the vertical optical axis OA. The inner frame 913 also has a frame wall 9131 extending from the frame wall at least one arm 9132, and a pivot 9133 perpendicular to the arm is formed at the end of the arm 9132; the pivot 9133 passes through the torsion spring 914 and is inserted into the frame After the three through holes 9115 are held by the third through holes 9115, the inner frame 913 can be rotated about the axis of the pivot 9133. In a preferred embodiment of the invention, the pivot 9133 has a shaft bore and provides a shaft 9135 through the third bore 9115 and the pivot 9133. In addition, the pivot 9133 and the rotating shaft 9135 can also be integrated. The third lens group 912 includes at least one lens 912A and is fixed to the inner frame 913. In other words, when the image of the object is captured, the inner frame 913 does not rotate about the axis of the pivot 9133, and the inner frame 913 moves linearly in the direction of the optical axis OA by moving the frame 911. Therefore, when an image of an object is taken, the arm 9132 of the inner frame 913 is substantially perpendicular to the optical axis OA. Fig. 5 is a perspective view showing the combination of the driving unit and the third lens unit. Referring to FIG. 4 and FIG. 5, the driving portion 93 includes a motor 931, a gear set 935 coupled to the motor 931 and mounted on the base 90, a lead screw 933 coupled to the gear set 935, and a lead screw 933 disposed therein. The compression spring 934 and the swing nut 932 that is screwed to the lead screw 933. After the one end of the lead screw 933 is coupled with the gear set 935 mounted on the base 92, the pressure 篑 934, the first through hole 9113 of the platform 9112 of the moving frame 911, and the tilting nut 932 are sequentially fitted into the lead screw 933. In a specific embodiment of the present invention, the platform 9112 of the moving frame 911 can be clamped therein by using a compression spring 934 and a tilting nut 932; further, when the motor 931 drives the gear set 935 and transmits to the lead screw 933, The moving frame 911 platform 9112 of the door will be moved in the direction of the optical axis ΟA by the rotational movement of the swaying nut 932 by the squeezing nut 932 and the compression spring 934 of 0757-A21238TWF (N2); 〇0105261 10 1273302. Figure 8 is a partial enlarged perspective view of the base. Referring to FIG. 4, FIG. 5 and FIG. 3, the base 92 has an obstruction frame 921 which is vertically coupled with the base 92 along the optical axis OA direction. Alternatively, the base % and the track frame 921 are integrally formed and mutually vertical. Further, one of the frame frames 921 has a straight groove 9211 extending in the optical axis direction; the lead screw 933 is perpendicular to the base 92, one end of which is coupled to the road frame 921 and the other end is coupled to the base 92. The tilting nut 932 has a protruding portion 9321, and after the tilting nut 932 is connected to the lead screw 933, the protruding portion 9321 of the rolling nut 932 is engaged in the straight groove 9211; when the lead screw 933 is rotated, The obstruction frame 921 restricts the tilting nut 932 from moving linearly in the direction of the optical axis 〇A and cannot be rotated. Figure 7A and Figure 7b show a perspective view of the base at different angles. Referring to FIG. 4, FIG. 7A and FIG. 7B, the base 9A has a protrusion 923 having a track surface 9231, wherein one end of the track surface 9231 is parallel to the base and the other end is perpendicular to the base, and A curved surface 9231 is connected to both ends. The inner frame 913 has a cam block 9134, and the cam block 9134 generally abuts the track surface 923A. The nut 932 has a pressing portion 9322, and the pressing portion 9322 abuts against the frame 9131 of the inner frame 913. When the distance between the rivet nut 932 and the base 92 is higher than a predetermined height ,, the pressing portion 9322 of the cocking nut 932 abuts the frame 9131 of the inner frame 913, and the cocking nut 932 is pressed. The spring 934 clamps the moving frame 911. Therefore, the motor 931 drives the lead screw 933 to rotate, and the moving nut 932 and the compression spring 934 drive the moving frame 911 and the inner frame 913 to move in the optical axis direction. When the distance between the cocking nut 932 and the base 92 is lower than the predetermined height ,, the pressing portion 9322 of the cocking nut 932 presses the frame 9131 of the inner frame 913 in the direction of the optical axis ;; when the lead screw 933 continues When the drive moves 0757-A21238TWF(N2); 〇0105261 1273302, when the screw 932 moves toward the base 92, the cam block 9134 of the inner frame 9i3 abuts the track surface 9231, and the self-existing surface 9231 is parallel to the base end 9231B. The arc/face 9231A slides to the track surface 9231 and the vertical end C of the base is the same as the same time. The tilting nut 932 continues to move with the compression spring 934 to move the moving frame 911 toward the base 92, and the perforation 9115 of the moving frame 911 is moved. The pivot 9133 of the inner frame 913 is held to rotate the inner frame 913 in the axial direction of the pivot 9133. Further, the frame plane of the inner frame 913 which is initially perpendicular to the optical axis 〇A is inverted to the outer side of the optical axis 〇A; at this time, the frame plane of the inner frame 913 and the frame plane of the moving frame 911 are mutually parent. Conversely, the inner frame 913 can also be flipped from the outer side of the optical axis 〇A such that the frame plane of the internal busy 913 is substantially parallel to the frame plane of the moving frame 911; at this time, the third lens group 912, the first lens barrel 20, and the second The lens barrel 3 is aligned with the optical axis and constitutes a photographable state. Figure 8 outlines the motion pattern of the moving frame moving in the direction of the optical axis. Referring to FIG. 4 and FIG. 8 , the platform 9 Π 2 has a second through hole 9114 ′ extending through the optical axis 〇 A direction. A main axis 936 parallel to the optical axis 〇 A direction passes through the second through hole 9114 and is fixed by the track frame 921 . The spindle 936. In addition, the base 92 has a counter shaft 922 extending along the optical axis 0A direction; and the other frame side of the moving frame 911, such as the moving frame side 911B opposite to the frame side 911A having the platform 9112, has a grip portion 9116 The sub-shaft 922 is sleeved by the grip portion 9116. Thereby, the moving frame 911 is used as a guide member for stably moving in the direction of the optical axis 〇A by the main shaft 936 and the counter shaft 922. Figure 9 outlines the assembly diagram of the torsion spring combined with the inner frame and the moving frame. Figure 10 shows the torsion spring action diagram of the inner frame flipping process. Referring to Figures 9 and 10, the torsion spring 914 has a pair of support ends 9141, 9142, a support end 9141 is secured to the inner frame 913 and another support end 9142 is secured to the moving frame 911. When the frame plane of the inner frame 913 is perpendicular to the optical axis OA, the angle between the pair of support ends 9141, 9142 is 0757-A21238TWF(N2); O0105261 12 1273302 is the maximum value; when the frame plane of the inner frame 913 is flipped to When the optical axis OA is outside, the torsion spring " 914 is subjected to torsional compression so that the angle Θ between the pair of support ends 9141, 9142 occurs to a minimum. Referring to FIG. 4, in the specific implementation method of the present invention, the third lens group 912 sequentially includes at least one lens 912A and a low-pass filter 912A from the object side. When the image of the object is not captured, the third lens group 91 is driven to rotate about the axis of the vertical optical axis by the driving portion 93, so that the third lens group 91 is away from the optical axis and is located in the first and second lens barrels 20, 30. One side. Since the low-pass filter 912 邻近 adjacent to the imaging end is also flipped over to the optical axis, it is accommodated; therefore, the present invention can further achieve the effect of shortening the length of the lens.
