To provide a photographic processing apparatus equipped with a print sorting device in which even when large prints and small prints are mixed, they can be accumulated with high sorting property and are easily taken out by a worker, and high-quality prints without scratches or curling can be provided.

A print sorting device 11 is provided with a regulating guide 112 so that when a small print is conveyed, the print is accumulated by the regulating guide 112 in a side of a tray 110 where a worker takes out the print and that when a large print is conveyed, the regulating guide 112 retreats and the print is accumulated on the tray 110. Thus, sorting property on accumulating prints is improved. A release portion 114 is formed in a stop plate 113 so as to prevent a small print from pinched between the tray 110 and the stop plate 113 when the small print leans against the stop plate 113.
