PROBLEM TO BE SOLVED: To provide an image reader and an image forming device which prevent slippage of a wire to prevent blurring of an image read and are miniaturized. SOLUTION: A driven pulley B306, which is fixed to a frame and is rotated to guide a wire 300 is made fixed so as not to be rotated, the wire 300 stretched in the second round is held by the frictional force of the pulley B306 which is not rotated, and this suppresses the slip of the wire 300 stretched in the second round around a second mirror base pulley 304, even if the wire 300 stretched in the second round is pulled by the wire 300 stretched in the second round around the second mirror base pulley 304.
