An image reading apparatus comprising:

• a reading unit configured to read an image of a document placed on a platen while moving along the document, the reading unit comprising a light source and image sensor, the light source being configured to radiate light onto the document through the platen, the image sensor being configured to receive light radiated from the light source and reflected on the document and convert the received light into image data;
• a body configured to accomodate the reading unit therein, the body comprising a bottom surface and a side surface configured to extend perpendicularly to the bottom surface;
• a control unit configured to coim 1 the reading unit;
• and
• a flexible flat cable comprising image data transmitting wires configured to transmit the image data from the reading unit to the control unit,
• wherein the flexible flat cable is divided into a first region and a second region by a slit, the first region and the second region being at least partially overlapped with each other in an overlapping portion of flexible flat cable when viewed in a thickness direction of the flexible hat cable, and the overlapping portion of the flexible flat cable is arranged along the side surface in the body, and changes its position with movement of the reading unit without being in contact with the bottom surface of the body, and
• wherein the image data transmitting wires are provided on the first region and are not provided on the second region.
