摘要： An image sensor system having very long Depth Of Focus (DOF) on the document plane and very short optical distance from the document plane to the image plane provides the advantages of both a lens reduction image sensor system and a contact type image sensor system. The inventive image sensor system thus provides a Long depth of Focus Contact type Image Sensor (Lf-cis) system that can be assembled in a compact and light weight module that is suitable for use in current image scanning systems (for example, flatbed type, paper feeder type, and handheld type). The invention also provides a compact and light weight flatbed type image scanning system. The CIS module may be modified such that two ends of the module higher than the rest of the module, a steel bracket holds the module and maintains the optical path in alignment, and a metal carriage having metal spring holds the module. The CIS module is self aligned to the bottom of the scanner glass. No optical adjustment or mechanical adjustment is required on the scanner assembly line. A central guideway and a low power stepping motor are provided to drive the entire module.
