Abstract: An automatic photographic paper processing apparatus wherein between an exposure unit (2) for printing a photographic paper and a transferring means (9) for discharging an exposed photographic paper a discharge accumulating unit (A2) for accumulating temporarily the exposed photographic paper is provided, so that when an amount of the photographic paper accumulated at the discharge accumulating unit (A2) is decreased the photographic paper is cut by operating a cutter unit (20) arranged at the downstream of the exposure unit (2) and then the transferring speed at the transferring means (9) is increased.An automatic photographic paper processing apparatus wherein a paper accumulating unit (102) for accumulating temporarily sensitive photographic materials fed from an exposure unit (2) is provided at a position preceding a developing processing unit (103) consisting of a plurality of processing tanks (131, 132, 133, 134).
