Description of the Invention: [Technical Field] The present invention relates to an image capturing mechanism used in a camera or other optical product, and more particularly to an image capturing mechanism having a smaller overall volume. [Prior Art] _Photographing in groups (4), or taking pictures in situations where the environment will shake, often causing blurring of the image due to shaking of the camera. Therefore, most cameras currently have an image stabilization function (Image StabiHzer), which makes the image feel The detector is arranged in a movable platform group, and is matched with a gyro sensor for measuring the degree of camera shaking, thereby controlling the platform group to move the image sensor according to the state of the camera. When the camera is turned on, the camera's internal telescopic lens will extend out of the body and receive external light to the image sensor in a stable manner to keep the image clear. When the camera is turned off, the lens groups of the extension head are stacked one on another and housed inside the body at a position adjacent to the platform group. As the camera becomes more and more lightweight, the size of each component of the camera must also change. 'Common methods are to make the structure design smaller and smaller, or as disclosed in the Japanese Patent Application No. 7 patent. The lens group of the telescopic lens is designed as a reversible structure, so that the lens group after storage can more effectively utilize the limited space in the body. Although the telescopic lens can reduce the volume by means of the above-mentioned changing mechanism design, in order to prevent the telescopic lens from interfering with the platform group for stabilizing the image, 201232027 still has a gap between the telescopic lens and the platform group to avoid unstable operation or It is a damaged situation' but the above gap also increases the overall size of the camera, making the camera unable to shrink. SUMMARY OF THE INVENTION It is therefore a primary object of the present invention to provide an image manipulation mechanism that has a thin overall thickness after being housed to reduce the space occupied by the inside of the camera. In order to achieve the above object, the image capturing mechanism provided by the present invention includes a platform group and a two lens holder, and the platform group is provided with an image sensor, and the platform is movably disposed on a base. The platform group has a top portion; the two lens holders are movably adjacent to or away from the platform group - the lens holder has a positioning portion, and when the lens holder having the positioning portion is adjacent to the platform group, the positioning portion Pushing against the top portion of the platform group causes the platform group to move to form a retreat space between the lens holder and the base. Another lens holder can be moved into the retreat space. In order to enable the platform group to be displaced, the top portion has a first oblique surface. The positioning portion has a second inclined surface. The oblique direction of the second inclined surface corresponds to the oblique direction of the first inclined surface. When the portion abuts against the top portion, the first slope contacts the second slope, so that the platform group is pushed and displaced and fixed. The detailed construction, features, assembly or use of the present invention will be described in the following detailed description of the embodiments. However, it should be understood by those of ordinary skill in the art that the present invention is described in the specification of range.
