摘要： A copying machine has a camera unit and a developer unit connected through a coupler, wherein the coupler includes feed paths along which a length of film is fed before and after exposure to a focused image of an original; a film cassette located adjacent to the feed path; a film carrier for supplying a length of unexposed film to the photographic or camera section, the film carrier being capable of running to and fro along a portion of the feed paths; an overlay sheet holder provided in opposite to the film carrier and movable in synchronism therewith; a transparent platen on which the film is placed with an overlay sheet covered thereon to shut out extraneous light; and a film sucking means mounted on the film carrier whereby a length of film after exposure is fed to the developer unit by being held by suction at its terminating end.
