Claim:
1. An image reading apparatus comprising: a scanner housing including a bottom wall surface, a frame spaced from and extending substantially parallel to the bottom wall surface, and a peripheral wall protruding from both of the bottom wall surface and the frame, the frame having an inner peripheral edge, the peripheral wall defining, with the bottom wall surface and the frame, an accommodation area within the scanner housing; a document support member supported by the scanner housing such that the document support member covers the accommodation area, the document support member having a flat surface and a document support surface opposite to the flat surface, the flat surface facing the bottom wall surface of the scanner housing at least inside the inner peripheral edge of the frame, the document support member being configured to support a document on the document support surface; a reader disposed in the accommodation area defined within the scanner housing and extending in a first direction parallel to the document support surface, the reader being configured to read an image of a document supported on the document support surface; a movable member holding the reader and configured to reciprocate in the accommodation area defined within the scanner housing in a second direction orthogonal to the first direction and parallel to the document support surface; and a flat cable connected to the reader at one end, the flat cable having a facing surface facing the flat surface of the document support member, wherein the peripheral wall of the scanner housing includes a particular wall extending in the second direction and a third direction orthogonal to the document support surface and defining one side of the accommodation area, wherein the facing surface of the flat cable has a first edge and a second edge opposite to the first edge in the first direction, the first edge being disposed along the particular wall extending in the second direction, the second edge being located overlapping the document support member at a position closer to a center of the document support member than a first segment of the inner peripheral edge of the frame of the scanner housing when viewed in the third direction, the first segment being closer to the particular wall than a second segment opposite the first segment in the first direction, wherein the particular wall of the peripheral wall of the scanner housing includes a restricting portion protruding from the particular wall in the first direction, the restricting portion being located between the frame of the scanner housing and the first edge of the facing surface of the flat cable in the third direction such that the restricting portion restricts the facing surface of the flat cable from contacting the flat surface of the document support member by contacting an outer portion, closer to the first edge than to the second edge, of the facing surface of the flat cable, and wherein the restricting portion protruding from the particular wall in the first direction includes a restricting surface located closer to the bottom wall surface of the scanner housing than the flat surface of the document support member, the restricting surface extending substantially parallel to the flat surface of the document support member such that, when the movable member reciprocates in the second direction, the outer portion of the facing surface of the flat cable contacts the restricting surface.
