(57) A reversal film inspecting apparatus is arranged such that a roll of photographic paper which has already been subjected to printing is successively fed from one of the takeup menas to the other, and has a print paper inspection board disposed between these takeup means. A moving means receives a reversal film slide from a desired one of a plurality of reversal film slide housing pockets formed in a magazine and moves the received slide to an observation window, and a reloading means returns a reversal film slide which has been observed at the window to the associated pocket in the magazine. Thus, it is possible for the operator to check pictures on a roll of photographic paper on the inspection board and to unload from the magazine a reversal film slide corresponding to a picture which needs to be re-printed for observation and further to input correction information required for re-printing in accordance with need.
