Abstract
A modularized carriage having a plurality of shock absorber struts is provided to allow a contact type image sensor module (CIS module) to contact tightly with the bottom surface side of the sheet table. The carriage has a plurality of holes formed on its bottom side. The bottom ends of the shock absorber struts are fixed to the bottom of the carriage. The shock absorber struts pass through the holes for supporting the CIS module in a manner such that the CIS module can contact tightly with the bottom surface side of the sheet table. Thus, while the CIS module is driven along the sheet table, the inventive carriage can absorb the vertical vibration of the CIS module and allow a document to stay within the scene depth of the CIS module. Since the present invention is a modularized carriage which is adaptable for various types of CIS modules and transmission mechanisms, the present invention can simplify the assembly and readjustment procedures of a CIS scanner. Moreover, the modularized carriage also helps to simplify the inner structure of the CIS scanner and reduces the size of the CIS scanner.
