More specifically _ the technology of the focal length of the lens module, and the invention is in the image capturing device of the digital camera or the like. [Previous technology] 10 With the popularity of digital video, the global market camera: and the multi-function mobile phone that provides camera function =: 曰, the camera provides the camera function The group consists of a compact camera module (CCM, ϋη·r). For example, the miniature camera 包含 group includes an AF actuator, a lens assembly, a 1 module, and a shutter assembly. Since the purpose of use is mostly portable, the miniaturization of the overall structure is very high. Among them, the lens assembly is composed of a plurality of lenses for focusing on the sensor. For the purpose of smooth focusing, the lens assembly and the sense line are arranged along the optical axis, and the passage between the lens assembly and the sensor has a great influence on the sharpness of the image. And parallel Figure 1 is an exploded view of a conventional lens module 1 。. The lens module 2 includes: a sensor 20 for detecting an image to generate a signal, and a 1 package 20 is disposed on a carrier 1; a lens assembly 5, including a plurality of The device is configured to receive one of the sensor 20 and its carrier w, a brother (not a connection device 70' interposed between the sensor 20 and the lens assembly 60; for connecting the carrier 10 On the carrying area 60. Between the sensors 2A, ° and the lens 6 1380684, the assembly 50 may further comprise an elastic rubber 30 and a glass 40 for stopping. In general, there are two Common factors may cause poor image clarity. One of them is that the distance between the lens assembly and the sensor is too large or too small for the light to focus on the sensor. The other is the lens. The poor level between the 5 pieces and the sensor causes the light to pass through the lens in the lens assembly and deviate from the optical axis, which also causes the image to become blurred. In the conventional lens module shown in Figure 1. Must be controlled by precisely controlled B machining accuracy and assembly errors. In order to improve the shortcomings of this type of lens module, it is also known that the sensor is first mounted on an adjustment device, and then the image is adjusted to the best, and then fixed. However, the size of these adjustment devices is too large, which is quite unfavorable for products with high requirements for miniaturization of the overall structure. In order to solve the problems that cannot be solved by the prior art, it is desired to have a new and improved lens. The module can optimize the spacing and parallelism between the lens assembly and the sensor by using an adjusting device, and does not increase the overall volume of the lens module. [Invention] 20 To solve the aforementioned problem, One object of the present invention is to improve the shortcomings of the conventional art by using a lens module with an adjustment member, and to improve the production yield of the lens module. Another object of the present invention is to The adjustment of the extra volume is not added to improve the shortcomings of the miniaturization of the overall structure of the prior art, so that the lens module should be 7
