Abstract: A rotary camera for photographing a plurality of original documents on microfilm and for recording information relating to the photographed original documents together with data concerning the conditions for photographing additional necessary data. The rotary camera has an exposure roller on which images of the original documents are focused to be photographed and unidimensionally arranged light emitting elements opposed to the exposure roller. The light emitting elements are selectively energized so that the microfilm is exposed to the data-writing lights forming any desired images of the data in the form of letters, numerals or marks while moving in contact with the exposure roller. The data to be recorded is designated and is put into the control system through a keyboard. A jam-mark may be recorded on the microfilm as the data in response to an output from a jamming detector.
