ABSTRACT:
An apparatus and method wherein a strip of photographic printing paper which has been subjected to exposure in a printer is intermittently fed by feeding rollers. The side edges of the foremost end part of the printing paper are inserted into an area between a rotational member and pressure contact arms which come in and out of contact with both the side edge portions of the rotational member. Then, the rotation member is rotated by an angular distance equal to an amount of feeding of the printing paper with the aid of the feeding rollers. The pressure contact arm comes in contact with the rotational member at the beginning time of rotation so that the foremost end part of the printing paper is clamped therebetween. After the rotational member rotates by a predetermined angle, it is stopped to form a loop of the printing paper. The rotational member is rotated again after a required amount of storage in the form of a loop is obtained so that the foremost end part is transported toward a delivery roller disposed on a developing machine side and at the same time the pressure contact arm is displaced away from the rotational member. Then, the pressure contact arms are displaced beyond both the side edges of the foremost end part of the printing paper which is located on the delivery roller so that they return to the initial stationary waiting position. Now, the rotational member which is kept in the stationary waiting state and the contact arms wait for coming of the foremost end part of the next printing paper.
