A flat-bed-type document scanner and an automatic-paper-feed-type document scanner are assembly integrally by use of first through third components to fabricate an image scanner. The first component is an assembly component which is prepared as a component which constitutes the automatic-paper-feed-type document scanner or a component to be attached to the automatic-paper-feed-type document scanner. The second component is an assembly structure member having a squarish U-shaped cross section and is adapted to be fitted onto a casing of the flat-bed-type document scanner. The assembly structure member has an engagement portion used for positioning of the assembly component, and a fixation portion used for fixation of the assembly component. The third component is a cover member disposed to cover the assembly structure member and the assembly component, and is fixed to the assembly structure member.
