ABSTRACT:
A rotary camera for photographing an original image on a document sheet so that a photographed image is formed on a frame of a microfilm roll. The document sheet is fed from a document feed port onto a rotary drum which comprises a hollow cylinder having an outer periphery provided with multiple small through-holes and suction means for sucking air through the multiple through-holes so that at least a zone of the document sheet exposed to photographing light is closely fitted over the outer periphery of the hollow cylinder. The photographed document sheet is stripped from the hollow cylinder by document stripping means disposed downstream of the suction means and then discharged through a document discharge port. Preferably, a buffer zone is provided between the suction means and the document stripping means to facilitate smooth stripping and preventing folding of the document sheet. The document feed port and the document discharge port is disposed through the front wall of the casing so that the operator can feed the document sheet while observing the image-bearing face of the document sheet. A film unit containing therein a microfilm roll is mounted on the rear side of the top wall of the casing and an optical system for passing the image-bearing light to the film unit is disposed rearward of the rotary drum, so that there is no risk that the image-bearing light is interfered by the lights entering from the document feed and discharge ports.
