  • Patent number: 4975733
    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.
