Abstract

A photographic apparatus for producing a visible image on a photosensitive nit including a photosensitive film mounted on a film mount. The apparatus includes: a first member having a supplying station, an exposure station, a developing station and a fixing station provided on a principal surface thereof; two transfer means, one for transferring the unit from the supplying station to the exposure station and or for transferring the unit from the exposure station to the developing station, and from the developing station to the fixing station; and driving means for driving the two transfer means. A latent image of an original is formed on the film at the exposure station, the latent image is developed at the developing station, and the developed image is fixed at the fixing station. The feature of this apparatus is that the function of holding the unit and guiding it to each of said stations is achieved by the first member, and independently the function of transferring the unit is achieved by the two transfer means, whereby the transfer of the unit from one station to another can be carried out securely without fail, and the mechanism of the apparatus can be simplified.

A photographic apparatus for producing a visible permanent image on a photosensitive film in a photosensitive unit which comprises a film mount and said photosensitive film mounted on said film mount, said photographic apparatus including:

a first member having a supplying station, an exposure station, a developing station and a fixing station provided along a path on a principal surface thereof, said photosensitive unit being supplied to said supplying station;
driving means;
first transfer means operatively coupled to and driven by said driving means and reciprocally movable thereby in a plane parallel to and spaced from said principal surface of said first member at a distance slightly larger than the thickness of said photosensitive unit for transferring said photosensitive unit along said principal surface from said supplying stataion to said exposure station by a first movement thereof;
exposure means operatively coupled to and driven by said driving means for subjecting said photosensitive film of said of photosensitive unit at said exposure station to a light reflected from an original from which said visible permanent image is to be produced, so as to form a latent image of said original on said photosensitive film;
second transfer means operatively coupled to and driven by said driving means and reciprocally movable thereby between said exposure station and said developing station and for transferring said photosensitive unit along said principal surface from said exposure station to said developing station;
developing means operatively coupled to and driven by said driving means for developing said latent image at said developing station so as to form a developed image, said first transfer means further transferring said photosensitive unit along said principal surface from said developing station to said fixing station by a second movement thereof;
and fixing means operatively coupled to and driven by said driving means for fixing said developed image at said fixing station so as to form said visible permanent image.
