In an image scanner having a flat bed type structure and an automatic document feeding type structure, the scanner includes: an image read unit at least including a lamp, a mirror and CCD sensors to read a manuscript which is put on the structure; an image control unit operatively connected to the image read unit to process an image read by the image read unit; a host computer operatively connected to the image control means; and the image control unit including a main printed-circuit board provided for the original functions of the image scanner, a main connector connecting the image control means to the host computer, a user printed-circuit board selectively provided by a user as an extended slot and the board being mounted within the image control unit, and a user connector connecting the main printed-circuit board to the user printed-circuit board. Further, the image scanner has a function of correction for a difference in an image output between the FB type and the ADF type by adjusting a change rate from the white/black reference level, the gain of the amplifier, the lamp current, or a predetermined conversion formula.
