Patent attributes
When an image-reading module moves along and scans a glass plate of an original document bed, a flexible wiring connecting the image-reading module to a fixing point takes various shapes depending on the position of the image-reading module so as to come close to or apart from a second metallic casing of an image-reading apparatus and a first metallic casing accommodating a signal processing unit. Since insulating members are provided on the first metallic casing, a predetermined or more distance between the wiring and the surface of the first metallic casing can be always kept constant, so that an analog signal transmitting through a conductive member within the wiring can be prevented from being largely affected by changes in electrostatic capacitance.
