Abstract
A film transporting device transports photographic film by driving a spool of a cartridge and a takeup spool which takes up the photographic film supplied from the cartridge by means of a single motor which is rotatable forward and backward. Unidirectional rotational driving force is transmitted from the motor to the spool and the takeup spool via one planet gear mechanism, and the photographic film is supplied from the cartridge, and then the takeup spool takes up the photographic film. The rotational driving force from the motor in the other direction is transmitted to the spool via the planet gear mechanism, and the photographic film is rewound into the cartridge. When the takeup spool takes up the photographic film, a one way clutch can absorb a difference of the transport speed between the takeup spool and the spool of the cartridge.
