several :: at the same time or alternately. It is called position, which is not conducive to quickly and accurately adjust the relative position of the same axis. U.S. Patent No. 5,424,873 discloses another lens fine adjustment device which is provided with a male thread around the lens barrel, and the mirror has a plurality of sets of female threads having different sets of female threads coaxial with the lens barrel. The center disk mirror of the other groups of female threads =: offset: 俾 can be corrected by the optical axis of the lens by selecting the lens cylinder to lock on the "female thread". However, such a design using multiple sets of lions = adjusting the axis does not only result in an increase in the length of the barrel, but the correction range is limited to the specific position corresponding to the yin, and accurate fine adjustment correction cannot be provided. In addition, U.S. Patent No. 4,989,950 discloses a lens adjustment device that utilizes an eccentric pin for adjustment, which utilizes an adjustment operation of an eccentric pin disposed radially to provide displacement of the lens relative to the central axis of the sleeve. . However, the design of the patented front does not provide radial fine-tuning of the lens. Japanese public open 60-15051 No. 1 practical new case reveals another - kind of profit 18614 6 1292498 = partial pin to adjust the lens such as the device, mainly used - $ center lucky by the life of 4 / L strike + Bo Yi ^ meat The setting of the heart lock: the lens provided to the lens is located at: έ, 1 I and the central axis are parallel to each other, when needed to adjust to 1 敕 π; ~ and between the mirror groups, due to the adjacent mirror group Obstruction, making = positive tools are difficult to access the eccentric pin and can not be adjusted, thus resulting in a huge limit on its library. The use of this technology must be carried out on the edge of the lens. The U-groove is used to observe the adjustment distance, and additional processing costs are added. Lens: This:: How to open - the ability to solve the above shortcomings of the prior art == set: to achieve cost reduction, reduce the installation space, reduce the time the lens is placed in the lens core, and can make the lens centering, apply Between the Yu and the Mirror Group, it is currently the subject of resolution. SUMMARY OF THE INVENTION In view of the above disadvantages of the prior art, the present invention provides a lens assembly with low cost and high integration. The other is to provide a lens alignment device with a well-defined position. #This reduces the difficulty of lens alignment, shortens the lens alignment, and this time in July - the purpose is to provide - not only It is suitable for single lens sets and can be applied to lens alignment devices between multiple mirror sets. Another object of the present invention is to provide a mirror alignment device that can reduce the installation space. For the purpose of the present invention and other objects, the present invention provides a lens alignment device for applying a lens on a support frame having a support end for adjusting the relative position of the central axis of the lens light reduction frame.调心装18614 7 1292498 - The system includes at least: 笫一-outer edge and the carrier, and the second rim is disposed on the lens in the relative position of the lens-direction: mouth = shaft acoustic carrier central axis The outer edge of the lens and the frame of the carrier are disposed opposite to the second direction of the lens in the second direction: micro: the optical axis of the lens and the axial center of the carrier; and the holding member is connected in a direction The first direction moves and raises two phases: eight:, use? Twisting the lens along the optical axis, the frame system can have the elastic force of the two directions. Positioning part of the adjustment. And the first recess and the portion for providing the first and second microend surfaces include, for example, a support for both the second and second trimming members. The first and the:== outer end faces can be respectively provided for driving to rotate and for example, the second micro-weeks are in the case of the lucky father, and the first fine-adjusting member and the second peripheral member respectively have The positioning portion and the eccentric portion of the mutual eccentricity may be a cylinder, and the acting portion may be a cam. "疋制今寺: The cow has a first-elastic element for pressing the lens to limit the movement, ^ / by the direction; the holder has two second elastic elements ★ Xuan No. 1! " For the opposite of the elastic force of the first and second directions. Preferably, the elastic members are respectively selected from the ones of the spring and the spring: in addition, the outer side of the retaining member has a fixing portion for the folding of the outer portion of the retaining member. Buckle, eight: The external part is provided with a convex part corresponding to the position for fastening. The first and the second 'the first direction and the second' are provided by the first fine direction member and the second fine adjustment member to provide the lens in the first and second directions of the first and second directions. Two == between 6. Degree angle to 12. Between the angles. Preferably, the 'different angle of the brother's angle is 90 degrees. Because of the lens alignment device proposed by Ben Sheming, the lens is finely adjusted by using a parallel to the mirror to lie between the outer edge of the brother and the carrier, for example, the eccentric pin, -:, the destructive member, It only needs to be equivalent to the eccentric pin diameter and space, and can use the thickness of the existing pipe wall, for example, the frame of the lens barrel. Therefore, the space of the lens alignment device can be reduced, so that the cost can be reduced. Reduce lens size and increase integration. X, the first, the fine adjustment member is provided with a groove on the outer end surface thereof to make it have directivity, and in the process of the imitation adjustment, the nominal position of the lens is easily determined, and the nominal position is used as the starting point of the lens fine adjustment, Effectively reduce the time of lens alignment. In addition, since the first and second fine adjustment parts are respectively disposed between the outer edge of the mirror 2 and the carrier parallel to the lens, they can be disposed in any application of the mirror group to overcome the lens in the prior art. When located between two sets of mirrors, the adjustment tool > is difficult to access the axially placed eccentric pin, which makes the lens alignment very difficult. It can be seen from the above that the application of the lens centering device of the present invention can be used to solve the various defects of the known technology, and the above-mentioned various substantial effects are enhanced and the value of the industrial utilization of the south is innocent.

The first major diameters 3〇d, 40d of the first and second fine adjustment members 3〇, 4〇 are abutted against the end surface 1〇a of the lens barrel 10, and the second large diameter 3〇e, 40e is passed through the first concave portion. I〇b, i〇d and so that the grooves 30a, 40a can be seen from the outside of the lens barrel to facilitate the operation of an adjustment tool (not shown) such as a screwdriver. 4A to 4C @ is a lens alignment device according to an embodiment of the present invention. 18614 1292498 ^The orientation of the target @然叙片2G is not adjusted to the previously disclosed embodiment, and is limited to the central axis of the lens barrel 1 It is also possible to set the second one according to the actual mirror group: the side axis is biased to the center axis. Further, the setting direction of the first fine adjustment member 30 and the first::: member 40 are at a mutual angle of 9 degrees. The traverse = can be between 6G degree and m degree angle, that is, the interlaced angle between the first direction and the first direction of the 系 is preferably between the degree angle and the degree angle, and the optimum line is 9 degrees. Angle. The mirror system provided by the present invention is disposed between the outer edge 2〇a of the lens 20 and the lens barrel 2〇 parallel to the lens 20 and is, for example, the first and second fine adjustment members 30, 40. The lens is finely adjusted, and only the space corresponding to the diameter of the eccentric pin is provided, and the installation space can be provided by using the thickness of the existing official wall such as the surface of the lens barrel, so that the lens can be reduced, and the installation space can be relatively reduced. The cost, and the reduction of the lens limb body machine and the improvement of the integration of the purpose of miniaturization. Moreover, the first and the U-thick members 30 and 40 are provided with grooves 3〇a and 4〇a on the outer end surface thereof to make the direction of the f-direction, and in the fine adjustment process, the nominal position of the lens 2〇 is easily determined. By using this public position as the starting point for lens fine adjustment, the time for lens alignment can be effectively reduced. In addition, since the first and second fine-tuning members respectively lie on the lens alignment device between the outer edge of the lens and the carrier, the lens is fine-tuned (four), so that it can be set in any mirror The group not only applies the application; the application of the lens alignment in the early-mirror group, but also applies to the mirrors between the mirror groups. Thus, it is difficult to overcome the conventional technique in which the lens is located between the two groups of mirrors. Close to the axially placed eccentric pin makes the lens alignment difficult and difficult. 18614 14 1292498 - [Second Embodiment] - Referring to Figure 5, there is shown a cross-sectional view of a second embodiment of the lens alignment device of the present invention.
