Abstract

A photographic image exposing apparatus capable of surely cutting off light leaked from an exposing head to avoid deterioration of quality of an image after projected. The photographic image exposing apparatus includes a first exposing section, provided at a position over a transporting path of a photographic paper, for projecting an image of a negative film on an area of the photographic paper to expose the photographic image thereon; and a second exposing section, provided at a position over the transporting path of the photographic paper, for exposing a photographic image captured as image data on a different area of the photographic paper from the area of the photographic paper exposed by the first exposing section, said second exposing section comprising a light source; an exposing head for outputting light of the light source onto the photographic paper to expose the photographic image thereon; and a light shielding mask for opening and closing an optical path between the light source and the exposing head.
