Focusing module
A focusing module for scanners includes a body which holds a lens and a transmission device on one side thereof to move the lens linearly and adjust a desired scanning focal length. Therefore the diaphragm may be enlarged to increase the scanning speed without reducing the depth of field and dropping Modulation Transfer Function, and to achieve a faster scanning speed and a desired scanning quality.
