Abstract: A carriage module for scanner comprises a case, an image sensor, a mirror set and a lens set. The image sensor, the mirror set and the lens set are arranged in the case and used to guide a reflected light from a document to be scanned as well as convert the reflected light to an electrical counterpart. The case composed of a first shell and a second shell with a larger length than that of the first shell. The second shell is movably arranged in the first shell and can be moved along a horizontal direction.

Abstract: The present invention provides an image scanning module including a first unit, a second unit, and a third unit. The first unit having a light source is used for retrieving a first image. The second unit is used for generating a second image by focusing the first image. The third unit is used for generating an electric signal responsive to the second image. The first unit, the second unit, and the third unit are modules discrete from each other.
