ABSTRACT:
An improved negative film carrier for a disc film adapted to be mounted on a handling board in a photographic printer in which images on negative films fitted into a number of film frames arranged along the periphery of the disc film in an equally spaced relation are printed one by one onto a photographic printing paper as the disc film is intermittently turned, said handling board including an exposure opening formed thereon through which light beam passes, is disclosed, wherein the improvement consists in that the negative film carrier essentially comprises a negative film mask plate serving as a base section for mounting the negative film carrier on the handling board, an exposure opening of said negative film mask plate being located in vertical alignment with the exposure opening of the handling board, a negative film mask holder adapted to be fitted on the negative film mask plate and including a negative film mask portion of which exposure opening is located in vertical alignment with the exposure opening of the negative film mask plate, a disc film holder turnably supported on the negative film mask holder in parallel to the upper surface of the latter and including means for intermittently turning the disc film by an angular distance corresponding to one pitch of film frames and a negative film retainer holder adapted to turn about a support shaft on an extension part extending rearward of the negative film mask plate and including a mask-shaped negative film retainer plate fixedly secured to the bottom of the fore part thereof.
