Abstract
An automatic film developing apparatus for developing a photographic film being guided by a leader, comprising a film separating and forming mechanism for separating the developed film conveyed from the developing section of the apparatus from the leader, and forming the separated portion of the film into a specified shape. The developed film is automatically separated from the leader by the film separating and forming mechanism, and, at the same time, the separated portion is formed in a predetermined shape so as not to be caught in the guide of the negative mask or in a predetermined shape so as to be easily wound up in the cartridge, thereby saving the labor and enhancing the job efficiency.
