Multi-pixel CCD image sensor

The utility model relates to a multiple-pixel number CCD image sensor, which comprises three single-sheet linear array CCD image sensors, a split joint platform which can fix the three single-sheet linear array CCD image sensors and heat conducting pipes arranged on the back sides of the single-sheet linear array CCD image sensors, wherein the heat conducting pipes clings to the back sides of the single-sheet linear array CCD image sensors through a fixed sheet which is connected with the split joint platform, the three single-sheet linear array CCD image sensors are sequentially and parallelly overlapped in Chinese character 'ping' or in step shape. The multiple image source CCD image sensor solves technical problems of the exist single-sheet linear array CCD image sensor that requirements of using the pixel numbers, the resolution factor and the capacity can not be satisfied, and the sensor has the advantages of more pixel numbers, simple structure, high imaging accuracy, optional structure size and good im
