PURPOSE:To reduce a blast and cost by driving a state changeover operating member by the abutting of an exposure device, original platen, or associative member and then switching a separation pawl to the 1st state. CONSTITUTION:A cam plate 26 is pivoted on a couple of slide blocks 23 of the exposure device rotatably around a shaft 25 parallel to the axis P of rotation of a photosensitive body 3 and a stopper 27 which controls the free end side of the cam plate 26 to a forward slanting attitude during the reciprocal exposure of the exposure device is provided. On the other hand, the state changeover operating member 24 which switches the separation claw 10 from the 2nd state Y to the 1st state X by sliding a rod 22 is provided in the reciprocal movement track Q of the cam plate 26. Then, the operating member 24 is lifted by the cam plate 26 during the reciprocal exposure of the exposure device and while the operating member 24 is lifted and driven, the claw 10 is switched from the 2nd state Y to the 1st state X.
