ABSTRACT:
An elastic fixing screw valve body is provided on a wall of a frame of an image-reading apparatus. The valve body allows a carriage fixing screw to be passed through the through-hole in the wall and the valve body when the image-reading device is prepared for transport to a new location so as to secure one or more carriages within the frame to the wall. The valve body also allows the carriage fixing screw to be removed when the image-reading device is prepared for normal scanning operation after being transported to the new location. In addition, the valve body acts to seal the interior space of the frame from invasion by dust via the through-hole when the carriage fixing screw is removed from the through-hole and normal scanning operation of the image-reading apparatus is resumed at the new location.
