Patent ID: 8724181

Claim:
An image reading apparatus comprising: a main body including a document receiving portion configured to receive a document from which an image is to be read; an image reader configured to move, along an under surface of the document receiving portion, between a first position located below a first end of the document receiving portion and a second position located below a second end, opposite to the first end, of the document receiving portion, the image reader being configured to read the image of the document received on the document receiving portion while moving in a predetermined direction; a controller disposed in the main body and configured to control image reading operations of the image reader; a cable having a first end fixed to a bottom surface of the main body below the second position and connected to the controller, and a second end connected to the image reader, wherein the cable includes an extension portion extending along the bottom surface of the main body in a direction parallel to a moving direction of the image reader when the image reader is in the first position; and a pair of protrusions in predetermined positions on the extension portion, one of the pair of protrusions protruding outward from one side of the cable in a width direction thereof and the other one of the pair of protrusions protruding outward from the other side of the cable in the width direction, wherein a regulation protrusion protrudes upward to a predetermined height from the bottom surface of the main body and is disposed in a position that is closer to the first position than the second position, and wherein the regulation protrusion is disposed outside the cable in the width direction such that no portion of the regulation protrusion overlaps the cable as viewed in a direction perpendicular to both the width direction of the cable and the moving direction of the image reader, and further such that, when the image reader moves toward the second position, the regulation protrusion regulates parallel movement of the pair of protrusions along the bottom surface of the main body and allows at least one of the pair of protrusions to move past an upper portion of the regulation protrusion in the moving direction of the image reader.
