ABSTRACT:
A combined camera and viewer capable of operating selectively under camera and projector modes one at a time, and being, when under the camera mode, operable to expose image information on a photosensitive film having a plurality of frames, and being, when under the projector mode, operable to project onto a screen an image recorded on the photosensitive film, which apparatus comprises a film transporting mechanism for transporting the film to bring any one of the frames to one of exposing and projecting positions, a detector for detecting whether or not such any one of the frames has been brought to such one of the exposing and projecting positions, and a discriminator for discriminating whether or not the image has been recorded on any one of the frames. When the apparatus is under the camera mode and the discriminator determines that the image information has been recorded on any one of the frames, such one frame is inhibited from being brought to the exposing position, and when the apparatus is under the projector mode and the discriminator determines that the image information has not yet been recorded thereon, such one frame is inhibited from being brought to the projecting position.
