Abstract: A document size detecting device with the arm which folds by interlocking with the reciprocating motion of the optical system of the image forming apparatus and extends and contracts by interlocking with the reciprocating motion of the optical system. The optical sensor for detection of the document size is installed at a prescribed position of the arm and the feeder line for the light source is held.
