ABSTRACT:
The present invention discloses a new information reading apparatus which employs a CIS module for reading the image information from a sheet. The invention is characterized by using a single guiding device for guiding and supporting a CIS carriage in balance while contacting tightly with the bottom surface side of the sheet table. Since the space between the CIS module and the sheet table can be controlled this way, we can assure the sheet in focus. Consequently, the picture quality of the images generated by the CIS scanner can be improved.
